Under the action of the reset spring, the telescopic slider is pulled back to reset itself after the pressure in the main air platform is deflated.

[0008] Preferably, a rubber clamping end is fixedly mounted on the outer end of the telescopic slider, which can effectively avoid scratching the surface of the copper bushing and increase the clamping friction.

[0009] Preferably, the hollow screw is provided with threads, and the airtight inner screw hole rod is provided with threads that mesh with the hollow screw. The working height of the hollow screw can be adjusted by rotating the hollow screw, which is more convenient.

[0010] Preferably, there are at least three sliding arms.

[0011] The advantages and positive effects of the utility model are: the clamping height can be adjusted, copper sleeves of different specifications can be clamped without loss, the clamping response is rapid, and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS
