A stabilizing elastic connecting plate 34 is provided on the lower opening and closing swing notch 33, and the two ends of the stabilizing elastic connecting plate 34 are respectively connected to the side walls on both sides of the lower opening and closing swing notch 33. The clamping driving member can tighten the size of the lower opening and closing swing notch 33 by pressing the driving end so that the two clamping jaws 4 are away from each other.

[0026] The arrangement between the swing fulcrum portion 35 and the two swing portions 36 allows the two swing portions 36 to swing around the swing fulcrum portion 35 , and the two swing portions 36 are symmetrically arranged on both sides of the central axis through the upper opening and closing swing notch and the lower opening and closing swing notch 33 .

[0027] By stabilizing the elastic connecting plate 34, the stability of the swinging of the two swinging parts 36 can be effectively guaranteed, acting as a ligament connection, ensuring the stability of the two swinging parts 36 during long-term use, providing a stable pulling force, and avoiding the clamping position from being biased to the left or right during long-term use.

[0028] The number of the lower swing grooves 32 is two, and the shapes of the two groups of lower swing grooves 32 are U-shaped.

When the moving end of the first driving cylinder 5 contracts, the driving end lacks the action of external force, and restores to the initial state under the action of the clamping force elastic part and the material of the clamping part 3 itself, and the two clamping jaws 4 clamp the material.

[0046] The tightening portion is a tightening inclined surface arranged on the side walls on both sides of the driving groove 61, and a driving inclined surface 40 matching the tightening inclined surface is arranged on the outer side of the driving end.

[0047] Through the cooperation of the tightening slope and the driving slope 40, during the rising process of the moving end of the first driving cylinder 5, the tightening slope continuously squeezes the tightening slope, so that the lower opening and closing swing gap 33 is tightened toward the central axis, that is, the lower part of the swing degree swings toward the central axis, realizing the process of the clamping jaws releasing the material.

[0048] As can be seen from the above, the beneficial effect of the utility model is that: adopting its mechanism can effectively solve the problem of the clamp in the prior art that the clamp is prone to loosening of the jaws after long-term use, resulting in the clamping being biased to the left or right, affecting the concentricity of the clamped material processing.
