As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12, FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17, FIG. 18, FIG. 19, and FIG. 20, an embodiment of the present disclosure provide a retractable pickup device, including: a telescopic rod subassembly 10, a control handle subassembly 20 mounted at one end of the telescopic rod subassembly 10, a chuck subassembly 30 mounted at the other end of the telescopic rod subassembly 10, and a driving subassembly 40 mounted in the chuck subassembly 30. The driving subassembly 40 is in driving connection with the chuck subassembly 30. The control handle subassembly 20 is in driving connection with the driving subassembly 40, so that the control handle subassembly 20 drives the chuck subassembly 30 to be closed and opened through the driving subassembly 40 to achieve picking and placement of an object.

A clamp device that is complex in both structure and operation on the market is improved. By means of disposing the control handle subassembly 20, the driving subassembly 40 that is in driving connection with the control handle subassembly 20, and the chuck subassembly 30 that is in driving connection with the driving subassembly 40, in actual operations, the control handle subassembly 20 is operated to drive the chuck subassembly 30 to be closed and opened through the driving subassembly 40, so as to achieve picking and placement of the object. Therefore, the retractable pickup device after the improvement is simple in both structure and operation, which further improves the operation experience of a user.

Specifically, the chuck subassembly 30 includes a clamping jaw body 31, and clamping jaw heads 32 which are symmetrically arranged on two sides of the clamping jaw body 31 and are in pivot-hinge to the clamping jaw body 31. A linkage part 321 is arranged at a tail of each clamping jaw head 32. The linkage part 321 extends into the driving subassembly 40.

During an operation, after the driving subassembly 40 slides towards a position away from the clamping jaw heads 32, the driving subassembly 40 drives the clamping jaw heads 32 to be closed through the linkage parts 321. After the driving subassembly 40 slides towards the clamping jaw heads 32, the driving subassembly 40 drives the clamping jaw heads 32 to be opened through the linkage parts 321.

In order to make the chuck subassembly 30 stabler when it clamps an object, an antiskid pad 322 is arranged on the inner side of each clamping jaw head 32, and an antiskid protrusion 3221 is arranged on the antiskid pad 322; and the antiskid pads 322 are used for increasing a friction force when the clamping jaw heads 32 clamp the object. Therefore, when the chuck subassembly 30 clamps the object, the antiskid pads 322 can further clamp the object so that it is difficult for the object to fall off, which further improves the stability of clamping the object by the clamping device.

In the present disclosure, the driving subassembly 40 includes: the driving subassembly includes a driving member body 41, a driving connecting rod 42 mounted on the driving member body 41, and an elastic reset member 43 sleeved on the driving connecting rod 42. The linkage parts 321 extend into the driving member body 41. One end of the elastic reset member 43 resists against the driving member body 41, and the other end of the elastic reset member 43 resists against the clamping jaw body 31.

In the operation process, after the driving connecting rod 42 is driven to drive the driving member body 41 to slide towards the position away from the clamping jaw heads 32, the clamping jaw heads 32 are closed, and the elastic reset member 43 is compressed and generates elastic restoring force. After the driving force disappears, the elastic restoring force pushes the driving member body 41 and the diving connecting rod 42 towards the clamping jaw heads 32, so that the clamping jaw heads 32 are opened.

In order to cause the driving member body 41 to be able to slide in the clamping jaw body 31, a driving member sliding chute 311 is provided at a position, corresponding to the driving member body 41, on the inner side of the clamping jaw body 31, and the driving member sliding chute 311 is used for allowing the driving member body 41 to slide.

In the present disclosure, the control handle subassembly 20 includes a handle 21, a trigger 22 mounted on the handle 21, and a clockwork spring box 23 which is in driving connection with the trigger 22. A pull rope 50 is arranged between the clockwork spring box 23 and the driving connecting rod 42. When the trigger 22 is pulled, the clockwork spring box 23 is driven to withdraw the pull rope 50 into the clockwork spring box 23, so that the pull rope 50 pulls the driving connecting rod 42 to move towards a direction away from the clamping jaw heads 32. When the trigger 22 is released, the clockwork spring box 23 drives the trigger 22 to be reset, and the elastic reset member 43 drives the driving connecting rod 42 to be reset. The driving connecting rod 42 pulls out the pull rope 50 from the clockwork spring box 23.

In order to enable the clockwork spring box 23 and the trigger 22 to drive each other, an axis of the clockwork spring box 23 is provided with an engagement gear 231. A position of the trigger 22 corresponding to the engagement gear 231 is provided with an engagement part 221. The engagement part 221 can be engaged with the engagement gear 231.

In the operation process, when the trigger 22 is pulled, the engagement part 221 is engaged with and drives the engagement gear 231 to drive the clockwork spring box 23 to be rolled back. When the trigger 22 is released, the engagement gear 231 of the clockwork spring box 23 is engaged with and drives the engagement part 221 of the trigger 22 to reset the trigger 22.

In the present disclosure, since one end of the telescopic rod subassembly 10 is provided with the control handle subassembly 20, and the other end of the telescopic rod subassembly 10 is provided with the chuck subassembly 30, the pull rope 50 passes through the telescopic rod subassembly 10, and the telescopic rod subassembly 10 is used for adjusting a distance between the control handle subassembly 20 and the chuck subassembly 30, which is convenient for a user to pick up objects spaced apart from the user at different distances.

Specifically, the telescopic rod subassembly 10 includes: an outer connecting rod 11, an inner connecting rod 12 plugged to the outer connecting rod 11 to do extend-retract motion, and a locking member 13 capable of restraining the inner connecting rod 12 from doing the extend-retract motion relative to the outer connecting rod 11. The locking member 13 includes an elastic self-locking member 131 mounted on the outer connecting rod 11 and a nut 132 sleeved on the inner connecting rod 12. The inner connecting rod 12 passes through the elastic self-locking member 131 and extends into the outer connecting rod 11.

In the operation process, the inner connecting rod 12 does the extend-retract motion relative to the outer connecting rod 11 to adjust the length of the telescopic rod subassembly 10. The nut 132 is then tightened on the elastic self-locking member 131 to enable the elastic self-locking member 131 to resist against the inner connecting rod 12, so that the inner connecting rod 12 is locked relative to the outer connecting rod 11. When the length of the telescopic rod subassembly 10 is required to be adjusted again, the nut 132 is loosened from the elastic self-locking member 131 to enable the elastic self-locking member 131 to be released from the inner connecting rod 12, so that the inner connecting rod 12 is unlocked relative to the outer connecting rod 11. Therefore, the length of the telescopic rod subassembly 10 can be adjusted again.

In order to enable the inner connecting rod 12 not to rotate when the outer connecting rod 11 does the extend-retract motion, the elastic self-locking member 131 is provided with a limiting protrusion 1311. A position of the inner connecting rod 12 corresponding to the limiting protrusion 1311 is provided with a limiting slot 121. The limiting protrusion 1311 is clamped in the limiting slot 121 and can slide in the limiting slot 121, so as to restrain the inner connecting rod 12 from rotating relative to the outer connecting rod 11.

The implementation modes of the present disclosure are described in detail above in conjunction with the accompanying drawings, but the present disclosure is not limited to the described implementation modes. For those skilled in the art, various changes, modifications, alterations, and transformations are made to these implementation modes without departing from the principle and spirit of the present disclosure, and shall still fall within the protection scope of the present disclosure.
