[0026] Specifically, the threaded rod 2 is rotated to drive the pushing block 3 to translate, and the pushing block 3 translates and drives the first connecting rod 5 and the second connecting rod 7 to rotate. The rotation of the second connecting rod 7 drives the clamping block 10 to translate forward and backward. The clamping block 10 translates and drives the third connecting rod 11 to rotate, thereby clamping the pneumatic component and preventing the pneumatic component body 13 from shaking during work, causing the dust cover to fall off.

[0028] Specifically, the sliding block 15 is manually slid inside the shell 14, and the sliding block 15 stretches the tension spring 16 under the restriction of the fixed plate 17. The sliding block 15 drives the rack 19 to translate, and under the restriction of the gear 20 and the limit plate 18, the rack 19 is prevented from being offset during translation.
