The working principle is as follows:
when a workpiece needs to be clamped, firstly, the horizontal section of the movable jaw 2 slides on the vertical section of the jaw body 1, the horizontal section of the jaw body 1 is pressed on the top of the workpiece, the presser foot 16 of the horizontal section of the connecting plate 3 is pressed on the bottom of the workpiece, then the movable jaw 2 and the top of the movable handle 5 are gripped, the movable handle 5 moves inwards, the bottom of the movable handle 5 pushes the downward inclined section of the connecting plate 3 to rotate downwards through the handle rivet 6, the tension spring 13 is in a stretching state, and under the action of the support plate rivet 4, the horizontal section of the connecting plate 3 drives the presser foot 16 to rotate upwards to clamp the workpiece. In the process that the movable handle 5 moves inwards, the movable handle 5 can drive the support plate 7 to move inwards through the lifting piece 10, when the two support plate rivets 8 of the support plate 7 and the handle rivets 6 of the movable handle 5 are in a straight line, the support plate 7 can support and position the movable jaw 2, the movable handle 5 and the connecting plate 3 in the process due to the matching limiting effect of the arc-shaped limiting part 12 of the lifting piece 10 and the protruding part 9 of the support plate 7, and the workpiece can still be clamped when the movable jaw 2 and the top of the movable handle 5 are loosened.
When the clamping force needs to be adjusted, the adjusting screw 19 is adjusted, and when the adjusting screw 19 moves inwards, the rotating angle of the support plate 7 is reduced, so that the opening angle between the movable handle 5 and the downward inclined section of the connecting plate 3 is reduced, the opening amount between the movable handle 5 and the movable jaw 2 is reduced, and the clamping force is reduced; when the adjusting screw 10 moves outwards, the opening angle between the movable handle 5 and the downward inclined section of the connecting plate 3 is increased, the opening amount between the movable handle 5 and the movable jaw 2 is increased, and the clamping force is increased.
When a workpiece needs to be loosened, the top of the lifting piece 10 is pressed towards the direction of the movable handle 5, the top of the lifting piece 10 rotates towards the direction of the movable handle 5, under the action of the lifting piece rivet 11, the arc-shaped limiting part 12 at the bottom of the lifting piece 10 can inwards push the protruding part 9 of the support plate 7, the bottom of the support plate 7 can outwards rotate around the support plate rivet 8, the movable handle 5 can be opened under the action of the reset force of the tension spring 13, the downwards inclined section of the connecting plate 3 upwards rotates, under the action of the support plate rivet 4, the horizontal section of the connecting plate 3 can drive the presser foot 16 to downwards rotate to loosen the workpiece, and therefore quick tightness of the workpiece is achieved.
The above-described embodiments should not be construed as limiting the scope of the utility model, and any alternative modifications or alterations to the embodiments of the present invention will be apparent to those skilled in the art.
The present invention is not described in detail, but is known to those skilled in the art.
