The sliding block 320 is engaged with the sliding slot 120 and can move along the sliding slot 120, one end of the spring 330 is connected to the first fixing block 310, and the other end is connected to the sliding block 320. When an external force is applied to the first end of the top block 200 to make the first engaging portion push the second engaging portion, the sliding block 320 moves along the sliding slot 120 toward the first fixing block 310, and the spring 330 is in a compressed state. When the external force is removed and the top block 200 is reset, the reaction force generated by the compression of the spring 330 pushes the sliding block 320 to reset, thereby realizing the clamping and positioning of the to-be-clamped member 700.
By adopting the arrangement form, the structure is simple, and the processing is convenient.
Optionally, the sliding block 320 includes a body 321, a first sliding portion 322 and a first supporting portion 323, the first sliding portion 322 is located on the bottom wall of the body 321, the first sliding portion 322 is clamped in the sliding slot 120, and a second clamping portion is configured at a position corresponding to the first clamping portion; the first supporting portion 323 is located on the sidewall of the body 321 facing the second clamping assembly 400, and the first supporting portion 323 is located above the top block 200.
The bottom wall of the body 321 is provided with a first sliding part 322 adapted to the sliding chute 120, for being clamped to the sliding chute 120. In this way, the stability of the sliding block 320 during the movement along the sliding slot 120 can be effectively improved.
A first supporting portion 323 is disposed on a side wall of the body 321 facing the second clamping assembly 400, and the first supporting portion 323 is located above the top block 200. Thus, the first supporting portion 323 has a supporting function on the to-be-clamped member 700 placed in the clamping space, and further can effectively prevent the to-be-clamped member 700 from contacting with the top block 200, so that the to-be-clamped member 700 is driven to move due to the movement of the top block 200.
Optionally, a first card slot 210 is configured on a side of the top block 200 facing the first sliding portion 322, the first card slot 210 is adapted to the first sliding portion 322, so that at least a part of the first sliding portion 322 is located in the first card slot 210, and a first side wall of the first card slot 210 is configured as a first wedge-shaped surface 211; when an external force is applied to the first end of the top block 200, the first wedge-shaped surface 211 of the top block 200 pushes the second wedge-shaped surface 324 of the first sliding portion 322, so that the first sliding portion 322 moves toward the first fixing block 310 along the sliding slot 120; when the external force is removed, the first sliding part 322 is reset, the top block 200 is reset, and at least part of the first sliding part 322 is located in the first clamping groove 210; the first side wall of the top block 200 is located rearward of the second side wall in the advancing direction of the top block 200.
A first locking groove 210 is formed inward on the side of the top block 200 that slides, and the first locking groove 210 corresponds to the sliding groove 120 and is adapted to the first sliding portion 322, so that at least a part of the first sliding portion 322 is located in the first locking groove 210. Meanwhile, the first sidewall of the first card slot 210 is configured as a first wedge-shaped surface 211, i.e., a first card portion. The first sliding portion 322 is configured as a second wedge surface 324 corresponding to the first wedge surface 211, i.e. a second clamping portion. The first wedge surface 211 abuts the second wedge surface 324 when at least a portion of the first slider 322 is positioned in the first card slot 210.
When an external force is applied to the first end of the top block 200, so that the top block 200 moves toward the inside of the base 100 along the slide way 110, at this time, the first sliding portion 322 is clamped in the first clamping groove 210 of the top block 200, and due to the arrangement of the first wedge-shaped surface 211 and the second wedge-shaped surface 324, the first wedge-shaped surface 211 of the first top block 200 can push the second wedge-shaped surface 324 of the first sliding portion 322 to continuously move toward the inside of the base 100. The first wedge surface 211 pushes the second wedge surface 324 to provide a pushing force to the second wedge surface 324, so that the first sliding portion 322 can move toward the first fixing block 310. Further, when the top block 200 moves the sidewall of the top block 200 to block the sliding slot 120, at this time, it is the maximum distance that the sliding block 320 moves.
After the external force is removed, the top block 200 is reset, and when the sliding groove 120 of the top block 200 corresponds to the sliding groove 120, the sliding block 320 is reset, and at least a part of the first sliding part 322 is clamped into the first clamping groove 210, so that the clamping and the positioning of the to-be-clamped member 700 are realized.
With this arrangement, the first slot 210 on the top block 200 is engaged with the first sliding portion 322 through the top block 200, so that the top block 200 can push the sliding block 320. On the other hand, the first sliding portion 322 is clamped into the first clamping groove 210 of the top block 200, so that the top block 200 is limited, and the phenomenon that the top block 200 is separated from the slideway 110 due to the fact that the top block 200 moves too far when being reset is effectively avoided.
Optionally, the first clamping assembly 300 further includes a first stopper 340 and a second stopper 350, the first stopper 340 is disposed on a first side of the sliding block 320; the second stopper 350 is disposed on the second side of the sliding block 320, and the second stopper 350 and the first stopper 340 together enclose a sliding space, so that the sliding block 320 moves along the sliding groove 120 in the sliding space.
A sliding space is defined by the first stopper 340 and the second stopper 350, so that the sliding block 320 moves along the sliding groove 120 in the sliding space. In this way, the sliding block 320 is effectively prevented from deviating from the sliding slot 120 during the moving process, and the normal use of the positioning and clamping device is further prevented from being affected.
