The actuating component 112 is received in a space S of the driving component 111 and abuts against the driving component 111, so as to bias the driving component 111 to rotate around a rotating axis R0. The abutting kit 113 is configured to engage with the driving component 111 for stopping rotation of the driving component 111. The first ratchet component 114 is coaxially rotatable relative to the driving component 111. The driving source 13 is coupled to the first ratchet component 114, so as to drive the first ratchet component 114 to rotate. The second ratchet component 115 is coaxially rotatable relative to the driving component 111 and configured to be driven by the first ratchet component 114 to rotate. The abutting kit 113 is biased to engage with the driving component 111 for stopping rotation of the driving component 111 and is driven to disengage from the driving component 111 by the first ratchet component 114 or the second ratchet component 115 for allowing the actuating component 112 to drive the driving component 111 to rotate. The driven component 116 is movably engaged with the driving component 111, and the inserting component 117 is disposed on the driven component 116. The driven component 116 is configured to be driven by the driving component 111 to move when the driving component 111 is driven to rotate by the actuating component 112, and the inserting component 117 is movable together with the driven component 116 when the driven component 116 is driven to move by the driving component 111.

However, the present invention is not limited to this embodiment.
Please refer to FIG. 5. FIG. 5 is a diagram illustrating the driving source 13 is coupled to the inserting assembly 11 according to the first embodiment of the present invention. As shown in FIG. 5, the driving source 13 is coaxially connected to the first ratchet component 114 by a shaft coupling 118, e.g., a rigid coupling or a flexible coupling. However, the present invention is not limited to this embodiment. For example, in another embodiment, the driving source can be connected to the first ratchet component by a belt pulley drive mechanism or a gear drive mechanism.
Please refer to FIG. 2 and FIG. 4 to FIG. 12. FIG. 6 is a diagram of the first ratchet component 114 and the second ratchet component 115 according to the first embodiment of the present invention. FIG. 7 and FIG. 8 are diagrams of the inserting assembly 11 in a first used state at different views according to the first embodiment of the present invention. FIG. 9 and FIG. 10 are diagrams of the inserting assembly 11 in a second used state at different views according to the first embodiment of the present invention. FIG. 11 and FIG. 12 are diagrams of the inserting assembly 11 in a third used state at different views according to the first embodiment of the present invention. As shown in FIG. 2 and FIG. 4 to FIG. 6, the second ratchet component 115 is resiliently deformed and not driven by the first ratchet component 114 when the first ratchet component 114 rotates along a first rotating direction R1, and the second ratchet component 115 is driven by the first ratchet component 114 to rotate together with the first ratchet component 114 along a second rotating direction R2 opposite to the first rotating direction R1 when the first ratchet component 114 rotates along the second rotating direction R2.
As shown in FIG. 2, FIG. 5 and FIG. 6, in this embodiment, a cooperating portion 1141 can be formed on the first ratchet component 114, and the second ratchet component 115 can include a resilient arm 1151 configured to cooperate with the cooperating portion 1141. When the first ratchet component 114 rotates along the first rotating direction R1, the resilient arm 1151 can be resiliently deformed by an inclined structure 1141A of the cooperating portion 1141, such that the second ratchet component 115 is not driven by the first ratchet component 114. When the first ratchet component 114 rotates along the second rotating direction R2, the resilient arm 1151 can be abutted by an erecting structure 1141B of the cooperating portion 1141, such that the second ratchet component 115 is driven by the first ratchet component 114 to rotate together with the first ratchet component 114 along the second rotating direction R2.
Furthermore, when the inserting assembly 11 is in the first used state as shown in FIG. 7 and FIG. 8, the actuating component 112 biases the driving component 111 to rotate along the second rotating direction R2 around the rotating axis R0, and the abutting kit 113 engages with the driving component 111 at a first position P1 for stopping the driving component 111 from rotating away from the first position P1 along the second rotating direction R2. When the first ratchet component 114 rotates along the first rotating direction R1, the first ratchet component 114 drives the abutting kit 113 to disengage from the driving component 111 at the first position P1 as shown in FIG. 7 and FIG. 8, such that the actuating component 112 drives the driving component 111 to rotate from the first position P1 as shown in FIG. 7 and FIG. 8 to a second position P2 as shown in FIG. 9 and FIG. 10 around the rotating axis R0 along the second rotating direction R2. As shown in FIG. 9 and FIG. 10, when the actuating component 112 drives the driving component 111 to rotate from the first position P1 to the second position P2 along the second rotating direction R2, the abutting kit 113 engages with the driving component 111 at the second position P2 for stopping the driving component 111 from rotating away from the second position P2 along the second rotating direction R2.
Afterwards, when the first ratchet component 114 rotates along the second rotating direction R2, the second ratchet component 115 is driven by the first ratchet component 114 to rotate together with the first ratchet component 114 along the second rotating direction R2, such that the second ratchet component 115 drives the abutting kit 113 to disengage from the driving component 111 at the second position P2. When the second ratchet component 115 drives the abutting kit 113 to disengage from the driving component 111 at the second position P2, the actuating component 112 drives the driving component 111 to rotate from the second position P2 as shown in FIG. 9 and FIG. 10 to a third position P3 as shown in FIG. 11 and FIG. 12 around the rotating axis R0 along the second rotating direction R2.
As shown in FIG. 2, FIG. 4 and FIG. 5, in this embodiment, the first ratchet component 114, the second ratchet component 115 and the driving component 111 are arranged along the rotating axis R0, and the second ratchet component 115 is located between the first ratchet component 114 and the driving component 111. The abutting kit 113 is located at a position corresponding to an outer periphery of the first ratchet component 114, an outer periphery of the second ratchet component 115, and an outer periphery of the driving component 111.
Furthermore, as shown in FIG. 4 to FIG. 12, the abutting kit 113 includes a first abutting portion 1131, a second abutting portion 1132 and a connecting portion 1133 integrally connected between the first abutting portion 1131 and the second abutting portion 1132 and sleeved on a mounting structure of the case 12, which is not shown in the figures. The first abutting portion 1131, the second abutting portion 1132 and the connecting portion 1133 can be made of resilient material. The first abutting portion 1131 is biased to cooperate with a stopping protrusion 1111 of the driving component 111 and a first pushing protrusion 1142 of the first ratchet component 114, and the second abutting portion 1132 is biased to cooperate with the stopping protrusion 1111 of the driving component 111 and a second pushing protrusion 1152 of the second ratchet component 115. Besides, in order to allow the first pushing protrusion 1142 to push the first abutting portion 1131 only, an end of the first abutting portion 1131 protrudes beyond an end of the second abutting portion 1132 along a direction from the second ratchet component 115 to the first ratchet component 114, i.e., the end of the second abutting portion 1132 is located at a position lower than the first pushing protrusion 1142 along a height direction parallel to the rotating axis R0.
As shown in FIG. 7 to FIG. 12, the driving component 111 drives the driven component 116 to move along an inserting direction D1 for driving the inserting component 117 to move together with the driven component 116 along the inserting direction D1 when the actuating component 112 drives the driving component 111 from the first position P1 to the second position P2. The driving component 111 drives the driven component 116 to move along a retracting direction D2 opposite to the inserting direction D1 for driving the inserting component 117 to move together with the driven component 116 along the retracting direction D2 when the actuating component 112 drives the driving component 111 to rotate from the second position P2 to the third position P3.
Please refer to FIG. 8, FIG. 10, FIG. 12 and FIG. 13. FIG. 13 is a diagram of the driving component 111 and the driven component 116 according to the first embodiment of the present invention. As shown in FIG. 8, FIG. 10, FIG. 12 and FIG. 13, in this embodiment, the driving component 111 includes an inserting inclined surface 1112 and a retracting inclined surface 1113. The inserting inclined surface 1112 and the retracting inclined surface 1113 are connected to each other. The inserting inclined surface 1112 is configured to abut against the driven component 116 for driving the driven component 116 to move along the inserting direction D1 when the actuating component 112 drives the driving component 111 to rotate away from the first position P1 and toward the second position P2 around the rotating axis R0, and the retracting inclined surface 1113 is configured to abut against the driven component 116 for driving the driven component 116 to move along the retracting direction D2 when the actuating component 112 drives the driving component 111 to rotate away from the second position P2 and toward the third position P3 around the rotating axis R0.
Detailed description for operational principle of the automated injection system 1 is provided as follows.
When it is desired to use the automated injection system 1, the driving source 13 can be activated to drive the first ratchet component 114 to rotate along the first rotating direction R1 to drive the first pushing protrusion 1142 to push the first abutting portion 1131 of the abutting kit 113 to move outwardly to disengage from the stopping protrusion 1111 of the driving component 111, for allowing the actuating component 112 to drive the driving component 111 to rotate from the first position P1 as shown in FIG. 7 and FIG. 8 to the second position P2 as shown in FIG. 9 and FIG. 10 around the rotating axis R0 along the second rotating direction R2. When the actuating component 112 drives the driving component 111 from the first position P1 to the second position P2, the driving component 111 drives the driven component 116 to move along the inserting direction D1 by a cooperation of the inserting inclined surface 1112 of the driving component 111 and the driven component 116 for driving the inserting component 117 to move together with the driven component 116 along the inserting direction D1, so as to achieve insertion of the inserting component 117 into a patient's skin. In addition, when the actuating component 112 reaches the second position P2 as shown in FIG. 9 and FIG. 10, the abutting kit 113 engages with the stopping protrusion 1111 of the driving component 111 for stopping the driving component 111 from rotating away from the second position P2 along the second rotating direction R2. It should be noticed that during the aforementioned process, the first ratchet component 114 can continuously rotate along the first rotating direction R1 or stop rotating after disengaging the first abutting portion 1131 of the abutting kit 113 from the stopping protrusion 1111 of the driving component 111.
Afterwards, the driving source 13 can be further operated to drive the first ratchet component 114 to rotate along the second rotating direction R2. When the first ratchet component 114 rotates along the second rotating direction R2, the second ratchet component 115 is driven by the first ratchet component 114 to rotate together with the first ratchet component 114 along the second rotating direction R2 to drive the second pushing protrusion 1152 of the second ratchet component 115 to push the second abutting portion 1132 of the abutting kit 113 to move outwardly to disengage from the stopping protrusion 1111 of the driving component 111, for allowing the actuating component 112 to drive the driving component 111 to rotate from the second position P2 as shown in FIG. 9 and FIG. 10 to the third position P3 as shown in FIG. 11 and FIG. 12 around the rotating axis R0 along the second rotating direction R2. When the actuating component 112 drives the driving component 111 from the second position P2 to the third position P3, the driving component 111 drives the driven component 116 to move along the retracting direction D2 by a cooperation of the retracting inclined surface 1113 of the driving component 111 and the driven component 116 for driving the inserting component 117 to move together with the driven component 116 along the retracting direction D2, so as to achieve retraction of the inserting component 117 out of the patient's skin. Besides, when the actuating component 112 reaches the third position P3 as shown in FIG. 11 and FIG. 12, the driven component 116 is abutted by an end portion of the retracting inclined surface 1113, such that the driving component 111 is stopped from rotating away from the third position P3 along the second rotating direction R2. It should be noticed that during the aforementioned process, the first ratchet component 114 can continuously rotate along the second rotating direction R2 or stop rotating after disengaging the second abutting portion 1132 of the abutting kit 113 from the stopping protrusion 1111 of the driving component 111.
Understandably, in another embodiment, the second ratchet component can be omitted, and in order to achieve retraction of the inserting component driven by the driving component, the abutting kit can be driven to disengage from the driving component at the second position by another mechanism rather than rotation of the first ratchet component along the second rotating component.
