The control gear 611 is partially protruded from the fixed handle 110, so that an operator can conveniently hold the rotation control gear 611. The control gear 611 rotates to drive the rack 613 to move through the guide gear 612, and the rack 613 drives the sliding assembly 620 to move toward or away from the upper wall 431.
The sliding component 620 comprises a supporting rod 621 and a plurality of pushing rods 622, one end of each pushing rod 622 is fixedly connected with the supporting rod 621, the pushing rods 622 are distributed on one side of the supporting rod 621 facing the limiting strip 410 in parallel array, through holes are formed in the lower wall 432 of the limiting strip 410 between two adjacent limiting blocks 440, the pushing rods 622 are connected with the through holes in a sliding mode and used for turning up sliding blocks 490 located between the two limiting blocks 440, the hook-shaped ends of the buckling plug-in units 450 are clamped with the clamping grooves 462, and the sliding blocks 490 can directly slide towards the direction of the clamping mechanism 300.
The implementation principle of the embodiment 2 is as follows: during the process of controlling the clamping mechanism 300 to clamp the foreign matter by the operator, the guiding portion 122 drives the guiding rod 220 to move towards one end away from the clamping mechanism 300. At this time, the locking member 460 drives the slider 490 to move along the guiding curved surface 441 of the limiting block 440, and when the slider 490 moves to the gap between the two limiting blocks 440, the limiting curved surface 442 degree slider 490 plays a limiting role, so that the clamping mechanism 300 is in the current clamping state or the continuously closed state, the stroke of the clamping mechanism 300 is reduced, and the macro spring 510 is pressed to retract the slider 490 to have a macro adjustment stroke of 1mm-1.5mm between the two limiting blocks 440. The three groups of limiting blocks 440 can limit the travel of the clamping mechanism 300 three times to maintain the clamping state of the clamping mechanism 300, and at this time, an operator can cancel the external force to avoid damage to the clamping mechanism 300 caused by excessive external force. Between any two limiting blocks 440, an operator can rotate the control gear 611 and drive the push rod 622 to ascend through the guide gear 612 and the rack 613, and the push rod 622 pushes the slide block 490 to ascend, so that the locking piece 460 rotates until the clamping groove 462 of the locking piece 460 is clamped with the buckling plug 450, thereby disengaging from the limiting function of the limiting blocks 440. The operator pushes the slider 490 to the separation ramp 411, and the separation ramp 411 forces the locking member 460 to separate from the buckle insert 450, thereby causing the slider 490 to abut the stopper 440, such that the slider 490 again enters the limitable state.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
