The outer surface of the sliding rod 8 is fixedly connected with a support block 18, and multiple groups of sliding rods 8 can be connected through the support block 18, which can increase the stability of the sliding rod 8 when working.

[0027] A stabilizing block 17 is fixedly connected inside the fixed cylinder 7, and the outer surface of the stabilizing block 17 is slidably connected to the inside of the pressing plate 9. The stabilizing block 17 can support the upper part of the pressing plate 9 to prevent the pressing plate 9 from being damaged due to excessive pressure when pressing downward.

[0028] The sliding rod 8 is located between the pressure plate 9 and the inner wall of the fixed tube 7 and is covered with a spring 19 on the outside.
