When people need to use the equipment to screw the nut, firstly, people can take the plug 8 out of the slot 4 through the cross head 6, then people enable the third clamping block 22 to be positioned at the outer side of the nut, then people rotate the rotating block 502 in the positive direction, the rotating block 502 moves leftwards, the fixed rod 26 plays a role in guiding the movement of the rotating block 502, the rotating block 502 moves leftwards to drive the clamping rods 501 in the upper and lower directions to move oppositely, the elastic sheet 503 bends, the clamping rods 501 in the upper and lower directions move oppositely to drive the first clamping blocks 7 in the upper and lower directions to move oppositely, so as to drive the third clamping blocks 22 in the upper and lower directions to move oppositely, so that the nut is clamped by the third clamping blocks 22 in the upper and lower directions, then people rotate the handle 1 to drive the guide sleeve 3 to rotate through the guide rod 2, so as to drive the clamping rods 501 to rotate, the clamping rods 501 drive the third clamping blocks 22 to rotate through the first clamping blocks 7 until the nut is screwed out or screwed tightly, if people need to screw larger nuts, people can rotate the rotating block 502 in the opposite direction, so that the rotating block 502 moves rightwards, the fixing rod 26 plays a role in guiding the movement of the rotating block 502, under the action of the elastic sheet 503, the clamping rod 501 drives the third clamping block 22 to move away through the first clamping block 7, the distance between the upper and lower third clamping blocks 22 is increased, when people do not need to screw the nuts, people can move the third clamping block 22 leftwards, when the third clamping block 22 moves to a proper position, the upper third clamping block 22 moves downwards, the lower third clamping block 22 moves upwards, and the third clamping block 22 is taken out.
When people reuse the device, the L-shaped clamping block 24 can be rotated and moved forwards, the torsion spring 23 is twisted, after the L-shaped clamping block 24 leaves the clamping groove 25, people move the guide sleeve 3 leftwards or rightwards, after the guide sleeve 3 is adjusted to a proper position, people release the L-shaped clamping block 24, under the action of the torsion spring 23, the L-shaped clamping block 24 rotates backwards, the L-shaped clamping block 24 is clamped into the clamping groove 25, the position of the guide sleeve 3 is fixed, the position of the clamping rod 501 is fixed, and therefore the guide sleeve 3 can be prevented from sliding to affect the normal work of the device when people use the device.
It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
