The gear 17 engages with the tooth plate 18 through the teeth, driving the cross bar 6 to move. The baffle 19 prevents the gear 17 from driving the tooth plate 18 to move excessively, causing the tooth plate 18 and the gear 17 to fall off. By adding lubricating oil to the storage tank 21, the lubricating oil is extracted from the storage tank 21 through the action of the pump 22, and the lubricating oil is sent to the rotating rod 16 and the gear 17 by the liquid outlet pipe 23 to prevent the gear 17 from rusting and affecting the clamping effect of the clamp. The movable plate 7 is driven to move through the cross bar 6, and at the same time, the hydraulic push rod 11 drives the clamping hand 12 to clamp the object.
