The left and right connecting rods 5 are respectively connected with a clamping hand 6 through hinge seats. Meanwhile, the clamping hands 6 on the left side and the right side are respectively connected with a T-shaped guide rail 7, so that the clamping hands 6 and the guide rails 7 can horizontally slide on the shell 1. The end of the clamping arm 6 is connected with a clamping jaw device 8, and the positioning, clamping and carrying work of the object is realized through the clamping jaw device 8. When the device works, the cylinder 2 pushes the push rod 3 and the sliding block 4 to move downwards, and the clamping jaw devices 8 and the T-shaped guide rail 7 are fixed by the shell 1 and can only move horizontally, so that the push rod 3 moves downwards, the connecting rod 5 is opened, the left clamping jaw 6 and the right clamping jaw 6 move outwards together with the clamping jaw devices 8, and the process is the process of loosening objects. Conversely, the push rod is retracted upwards by the cylinder 2, the left and right clamping hands 6 and the clamping jaw devices 8 clamp objects inwards, and the clamping force is provided by the cylinder 2.
The operation of the jaws will now be described in detail with reference to figure 2. As shown in fig. 2, the jaw apparatus 8 includes a first clamping assembly 13, a second clamping assembly 14, a third clamping assembly 15, a base 12, a spring 11, a clamping push rod 17, a first-stage link a9, a first-stage link b19, a first-stage link c18, a second-stage link a9, a second-stage link b21 and a rotating shaft 20, wherein:
