It should be noted that the first through locking hole is slightly larger than the size of the slide rail 20, and the first blocking piece 34 may be formed by overlapping a plurality of plates.
In one example, the first handle 35 is rotatably disposed in the second clamping body 31, the top block 351 is disposed on the first handle 35, and when the first handle 35 rotates towards the first elastic member 36, the top block 351 abuts against the first blocking piece 34 and swings for a predetermined distance, and the predetermined distance is preferably that the first blocking piece 34 swings until the axial direction of the first locking through hole of the first blocking piece coincides with the length direction of the slide rail 20. The free end of the first handle 35 extends outside the second sandwich body 31 for manual operation.
In one example, two spring seats 361 are fixed in the second clamping body 31, the first elastic member 36 is a spring, one end of the spring is fixed in the spring seat 361, the other end of the spring is connected with the side surface of the first blocking piece 34, 362 is arranged at the other end of the side surface of the first blocking piece 34 opposite to the top block 351 to limit the position of the first blocking piece 34, and the spring can provide a reaction force for the first blocking piece 34 when the top block 351 pushes the first blocking piece 34 to deflect.

The second handle 38 is rotatably installed at a side of the second shutter 37, and the second handle 38 and the second elastic member 39 are respectively located at both sides of the second shutter 37, and the second shutter 37 is driven to be deviated by the rotation of the second handle 38.
It should be noted that the second locking through hole is slightly larger than the size of the slide rail 20, and the second blocking piece 37 may be formed by overlapping a plurality of plates.
The jointing clamp further comprises a retraction state and a propulsion state, in the retraction state, the second handle 38 acts to compress the second elastic piece 39, the second stop piece 37 swings backwards, and the inner wall of the upper part of the second locking through hole rubs with the sliding rail 20 and drives the sliding rail 20 to retract backwards; in the pushing state, the second blocking piece 37 is reset by the second elastic piece 39, and meanwhile, the second handle 38 is pushed to reset, and the second locking through hole pushes the sliding rail 20 to overcome the friction force between the first blocking piece 34 and the sliding rail 20, so that the second clamping body 31 moves forward relative to the sliding rail 20 by a predetermined distance.

The free end of the first handle 35 extends outside the second sandwich body 31 for manual operation.
It should be noted that the size of the mounting through hole is much larger than the external size of the slide rail 20, so that the second handle 38 does not contact the slide rail 20 when rotated.
In one example, a spring seat 361 is fixed in the second clamping body 31, the second elastic member 39 is a spring, one end of the spring is fixed in the spring seat 361, the other end of the spring is connected with the side surface of the second catch 37, and the other end of the second catch 37 is movably installed in the support 371, that is, the second catch 37 can move back and forth in the support 371.
