The device limits the main body through the groove of the bottom plate, and fixes the main body through the cooperation of the extension rod inside the groove and the connecting block. The equidistantly arranged extension rods make the main body more stable during use. The groove positions the main body, replacing manual positioning to make it more convenient for workers to install, effectively improving their work efficiency. The support rod supports the bottom plate, making the bottom of the main body suspended, allowing it to dissipate heat through the bottom during use, effectively preventing the device from being too stable, and effectively improving its work efficiency.

In the process of rotating, connecting rod 5 also drives internal hex nut 7 to move downward, thereby extruding spring 9 through circular ring 8, the springback force of spring 9 provides an upward thrust to internal hex nut 7, so that the top surface of each thread of connecting rod 5 and thread groove 6 is in close contact, effectively preventing the self-rotation of connecting rod 5.

[0032] As shown in Figure 4 , the side of the two extrusion plates 2 close to each other is provided with a plurality of positioning grooves 13, and the push plate 11 is clamped in the positioning groove 13; the two push plates 11 are inserted into each other and used for limiting the main body 101; the push plate 11 is inserted into different positioning grooves 13 to limit the main body 101 of different sizes.
