The stop wall 704 is located in a rotational direction of the eccentric piece 705 and is used to restrict a rotation angle of the eccentric piece 705. The clamping pin 707 rotates along the step 709 and may enter the fourth groove 703 during rotation. The eccentric piece 705 is sleeved with a compression spring 708, also referred to herein as a fifth elastic reset device. One end of the compression spring 708 abuts against the connecting portion 101, and the other end abuts against the handle 706. The compression spring 708 has an elastic force when being compressed. The elastic force abuts against the handle 706 to enable the clamping pin 707 to abut against the connecting portion 101. For example, the clamping pin 707 needs to move out of the fourth groove 703 to abut against the step 709. The compression spring 708 needs to be pressed to enable the elastic force of the compression spring 708 to further increase. In this case, the clamping pin 707 abuts against the connecting portion 101 with a greater force. That is, when the clamping pin 707 abuts against the step 709, the clamping pin is more difficult to rotate than in the fourth groove 703, that is, the clamping pin is more stable.
The fastener box component 2 is provided with a first dovetail 710, also referred to herein as a stop block 710. The first dovetail 710 may be plugged in the first dovetail groove 701 and may slide in an extension direction of the first dovetail groove 701. The first dovetail 710 is provided with an eighth groove 711. The first dovetail 710 is plugged in the first dovetail groove 701. After the fastener box component 2 is installed in position, the eccentric piece 705 rotates by a particular angle to be partially plugged in the eighth groove 711. The eccentric piece 705 may block a first dovetail 711, to prevent the first dovetail 711 from exiting from the first dovetail groove 701, that is, prevent the fastener box component 2 from being detached. In this way, the fastener box component 2 may be locked to the connecting portion 101. In this embodiment, when the eccentric piece 705 is located in the eighth groove 711, and the clamping pin 707 is located outside the fourth groove 703 and abuts against the step 709. Therefore, when the eccentric piece 705 is located in a state of being locked at the fastener box component 2, a greater force is required to rotate the eccentric piece 705. The fastener box component 2 is locked more stably.
In this embodiment, the first dovetail groove 701 is both an embodiment of a connecting piece and an embodiment of a guide structure; and the first dovetail 710 is both an embodiment of a first alignment structure and an embodiment of a fitting structure. In addition, after the first dovetail 710 is provided with the fourth groove 703, the first dovetail 710 is divided into two convex blocks, constituting an embodiment of a second alignment structure. The eccentric piece 705 is an embodiment of a locking piece.
As shown in
The fastening member 21 in another embodiment may also be, for example, independent of the fastener box component 2 as in Embodiment 8, and before the fastener box component 2 is connected to the gun body 1, the fastening member 21 is connected to the power member 13 in advance.
As shown in
As shown in
During fastening, the other end of the lever 304 is pressed to enable the lever 304 to rotate around the shaft 305. The lever 304 rotates to enable the sliding block 302 to move upward and drive the elastic sheet 308 to deform. The lever 304 rotates to slide to the right relative to the shaft 305. At the same time when the sliding block 302 moves upward, the lever 304 slides to the right until the lever 304 moves out of the jack 3021 of the sliding block 302. The sliding block 302 moves downward under the effect of the elastic sheet 308 to perform fastening. After pressing is released, the lever 304 resets under the effect of the fifth spring 307, and an end portion is inserted in the jack 3021 again.
The solution in any foregoing embodiment may be used for a connection solution between the fastener box component 2 and the gun body 1. As shown in the figures, referring to the connection solution between the fastener box component 2 and the gun body 1 in Embodiment 1, the connecting portion 101 in this embodiment is connected to a second locking hook 310. The second locking hook 310 has a V shape. An end portion of the second locking hook 310 is provided with a hook body (not shown in the figure). The hook body is used to hook the pin shaft 213 on the fastener box component 2. A second torsion spring 312 is further installed on the connecting portion 103. The second locking hook 310 rotates to enable the second torsion spring 312 to deform to generate an elastic force. The elastic force may enable the second locking hook 310 to reset to be kept in a state of hooking the pin shaft 213. During use, the second locking hook 310 hooks the pin shaft 213, and the connecting portion 101 is connected to the fastener box component 2. The second torsion spring 312 enables the second locking hook 310 to be kept in the state. The second locking hook 310 is pushed with a hand to rotate clockwise, and after a hook body 311 unhooks the pin shaft 213, the fastener box component 2 can be removed. In this case, the second torsion spring 312 deforms to generate an elastic force. The elastic force may enable the second locking hook 310 to reset and can help the second locking hook 310 to stably keep hooking at the position of the pin shaft 213.
In this embodiment, the first locking hook 107 and the second locking hook 310 are both locking hooks, and are generally referred to as a locking hook. The first torsion spring 108 and the second torsion spring 312 are respectively an embodiment of a sixth elastic reset device.
The power member 13 has an initial position and an end position during movement. The power member 13 shown in
When the fastening member 21 is first connected to the fastener box component 2 and is then connected to the power member 13, the initial position of the power member 13 overlaps the end position. When the power member 13 is located in the end position, the fastener box component 2 is then connected to the gun body 1 such that the power member 13 is connected to the fastening member 21 at the same time. During fastening, the power member 13 carries the fastening member 21 to move away from the initial position, and then returns to the initial position under the effect of power to implement fastening.
