In order to improve the stability of the screw rod 4 driving the sliding block 2 to slide, the one end of the screw rod 4 penetrating into the sliding block 2 is provided with a positioning plate 41, and a supporting spring 42 is arranged between the positioning plate 41 and the sliding block 2, the supporting spring 42 is sleeved on the screw rod 4, and one end of the supporting spring 42 abuts against the positioning plate 41, and the other end abuts against the sliding block 2. Through the buffering of the supporting spring 42 to the sliding block 2, the stability of the sliding block 2 sliding on the guide block 11 is improved.

[0028] With reference to Figs. 2-3 The driving motor 3 is provided with a driving gear 31, the screw rod 4 is provided with a driven gear 43, and the first transmission assembly comprises a transmission belt 51, the transmission belt 51 is sleeved on the driving gear 31 and the driven gear 43, and the transmission belt 51 is provided with teeth 52, and the teeth 52 are uniformly and spacedly arranged on the transmission belt 51. In use, the teeth 52 on the transmission belt 51 are engaged with the driving gear 31 and the driven gear 43. The driving motor 3 drives the driving gear 31 to rotate, the driving gear 31 drives the driven gear 43 to rotate through the transmission belt 51, and the driven gear 43 drives the screw rod 4 to rotate. In the process of use, the running mode of the transmission belt 51 is checked, the vibration absorption performance is good, the noise and impact can be effectively reduced, the transmission belt 51 has a certain elasticity and sliding property, and will slip in overload, so that the mechanical equipment is protected from damage, and the gear transmission may be damaged in overload.
