When the second inclined surface 210 and the third inclined surface 730 form an isosceles trapezoid with a downward opening, the workpiece has a downward movement tendency after being clamped, and the workpiece is clamped by the clamping device after being contacted with the bottom surface adjacent to the second inclined surface 210; when the second inclined plane 210 and the third inclined plane 730 form an isosceles trapezoid with an upward opening, the fixed clamping block 200 is further provided with a boss above the second inclined plane 210, and after the workpiece is clamped, the workpiece has a tendency of moving upward, and after the workpiece is contacted with the boss, the workpiece can be clamped by the clamping device. By arranging the second inclined surface 210 and the third inclined surface 730 in the lever clamp, the workpiece is simultaneously subjected to forces in three directions to be fixed when being clamped and positioned, and a better clamping effect is achieved.

In some embodiments of the present invention, a spring 800 is further included, one end of the spring 800 is connected to the lower end of the pulling block 400, and the other end is connected to the bottom of the support 100. For example, as shown in fig. 1 and 2, one end of the spring 800 is disposed at the bottom of the holder 100, and the other end of the spring 800 abuts against the lower end of the first pulling block 410. By arranging the spring 800 in the lever clamping device, when a workpiece is loosened, only the force applied to the first lever 500 is required to be stopped, and the first long force arm 520 does not need to be manually controlled to move downwards, and the spring 800 is used for resetting the first lever. Specifically, when the lever clamping device clamps the workpiece, the pull block 400 moves downward integrally to compress the spring 800, when the workpiece is released, the force applied to the first lever 500 disappears, the pull block 400 is no longer subjected to a downward force, the spring 800 recovers to deform to jack the pull block 400 upward, and the movable slider slides rightward in the first sliding groove 110 to release the workpiece.

In some embodiments of the present invention, the first lever 500 is further provided with a limiting bolt 530. For example, as shown in fig. 1 and 2, a limiting bolt 530 is disposed on the first long moment arm 520, and a nut 531 is disposed on the limiting bolt 530. By arranging the limiting bolt 530 and the nut 531 matched with the limiting bolt on the first lever 500, the moving distance of the movable clamping block 300 during loosening can be reduced, and the clamping efficiency is improved. Specifically, after the force applied to the first long force arm 520 is removed, the first long force arm 520 moves downward under the action of its own weight, and the first short force arm 510 pushes up the pull block 400 to move the movable clamping block 300 to the right. At this moment, install limit bolt 530 additional on first long arm of force 520, first long arm of force 520 just can be supported by limit bolt 530 after a distance that descends, first long arm of force 520 can not direct and support 100 contact, when the distance that first long arm of force 520 descends reduces, the ascending distance of first short arm of force 510 that corresponds with it, the ascending distance of pull block 400 and the distance that moves clamping block 300 right all can reduce, when the lever clamping device who has installed limit bolt 530 additional presss from both sides the work piece, the stroke that moves left of moving clamping block 300 is also littleer than the lever clamping device who does not install limit bolt 530 additional, lever clamping device's clamping efficiency has been improved effectively. The user can adjust the length that the limit bolt 530 stretches out at the lower end of the first long force arm 520 to meet the requirements of different unclamping distances in actual production.

In some embodiments of the present invention, a cylinder 900 is further included, and the cylinder 900 is used for driving the first lever 500. For example, as shown in fig. 1 and 2, the cylinder 900 is disposed at the lower end of the support 100, and the cylinder 900 faces one end of the first long moment arm 520. When the cylinder 900 works, the first long force arm 520 is jacked up, the first short force arm 510 presses the second long force arm, the second long force arm drives the second short force arm to move downwards in the process of moving downwards, so that the pull block 400 is driven to move downwards, and the pull block 400 moves downwards to drive a subsequent series of movements so as to finish the clamping action of the workpiece. The cylinder 900 works stably and reliably and responds quickly, and the cylinder 900 is arranged in the lever clamping device, so that the lever clamping device can clamp a workpiece quickly and continuously provide reliable clamping force.
