During the clamping process, no deformation will occur between the two clamping jaws 2, and the design of the reset elastic member 3 can provide a stable holding force, ensuring that the clamp maintains a stable clamping state during operation.

[0032] The design of the protrusion 40101 of the present application can provide stable support and guidance, ensuring the stability and accuracy of the clamp 2 during the adjustment process. The Z-shaped clamp 2 can make the clamp more reliable and efficient during operation. The adjustment end of the clamp 2 is slidably connected to the inclined side wall of the protrusion 40101, and this design makes the adjustment process more stable and accurate, which is conducive to adjusting the spacing of the clamp and maintaining the stability of the clamp.
