The push-pull rod penetrates through the lower clamp seat and horizontally moves inside the lower clamp seat, and the other end of the push-pull rod is movably connected to the other end of the upper clamp short handle. Then, the cylinder drives the push-pull rod to move left and right inside the lower clamp seat, thereby driving the upper clamp to swing on one side of the upper plate.
[0005] Preferably, a first cylindrical pin is arranged between the upper clamp short handle and the second lower clamp arm, and the first cylindrical pin horizontally penetrates through the second lower clamp arm and the upper clamp short handle. The upper clamp short handle swings between the second lower clamp arms with the first cylindrical pin as a movable fulcrum.
[0006] Preferably, a second cylindrical pin is arranged between the upper clamp and the first lower clamp arm, and the second cylindrical pin horizontally penetrates through the first lower clamp arm and the upper clamp. The upper clamp swings between the first lower clamp arms with the second cylindrical pin as a movable fulcrum.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-3 , in the embodiment of the present invention, the new clamp includes a lower clamp seat 2. At the front and rear ends on one side of the lower clamp seat 2, the first lower clamping arms 1 are horizontally arranged. And between the first lower clamping arm 1 and the lower clamp seat 2, there is a second lower clamping arm 4. And both sides of the second lower clamping arm 4 are respectively connected to the first lower clamping arm 1 and the lower clamp seat 2. Horizontally arranged between the first lower clamping arms 1 is a lower plate 5, and the lower plate 5 is located on one side of the first lower clamping arm 1. The short handle 11 of the upper clamp is movably arranged between the second lower clamping arms 4, and one end of the short handle 11 of the upper clamp is movably connected to the upper clamp 6. The other end of the upper clamp 6 is movably arranged between the first lower clamping arms 1, and there is an angle between the upper clamp 6 and the lower plate 5. At the other end of the lower clamp seat 2, there is a cylinder 3, and on one side of the cylinder 3, there is a drive connection with a push-pull rod 8. The push-pull rod 8 penetrates the lower clamp seat 2, and the push-pull rod 8 moves horizontally inside the lower clamp seat 2. And the other end of the push-pull rod 8 is movably connected to the other end of the short handle 11 of the upper clamp. Thus, when the cylinder 3 pushes the push-pull rod 8 to move along the left side inside the lower clamp seat 2, the push-pull rod 8 drives the short handle 11 of the upper clamp to swing between the second lower clamping arms 4, and then drives the upper clamp 6 to swing between the first lower clamping arms 1, so that the tail end of the upper clamp 6 is raised and the front end is pressed down to clamp and fix the material on the lower plate 5. Or when the cylinder drives the push-pull rod to move along the right side inside the lower clamp seat 2, the push-pull rod 8 drives the short handle 11 of the upper clamp to swing between the second lower clamping arms 4, and then drives the upper clamp 6 to swing between the first lower clamping arms 1, so that the tail end of the upper clamp 6 is lowered and the front end is raised to release the material.
[0020] A first cylindrical pin 10 is arranged between the upper clamp short handle 11 and the second lower clamp arm 4, and the first cylindrical pin 10 horizontally penetrates through the second lower clamp arm 4 and the upper clamp short handle 11. The upper clamp short handle 11 swings between the second lower clamp arm 4 with the first cylindrical pin 10 as the moving fulcrum, so as to perform power traction on the upper clamp 6 subsequently.
[0021] A second cylindrical pin 14 is arranged between the upper clamp 6 and the first lower clamp arm 1, and the second cylindrical pin 14 horizontally penetrates through the first lower clamp arm 1 and the upper clamp 6. The upper clamp 6 swings between the first lower clamp arm 1 with the second cylindrical pin 14 as the moving fulcrum, so as to clamp the material on the lower plate 5 subsequently.
[0022] A second joint pin 12 is arranged between the upper clamp 6 and the upper clamp short handle 11, and the second joint pin 12 horizontally penetrates through the upper clamp 6 and the upper clamp short handle 11. The upper clamp 6 and the upper clamp short handle 11 are movably connected through the second joint pin 12, so that the upper clamp short handle 11 can perform movable traction on the upper clamp 6 subsequently.
[0023] A first joint pin 7 is arranged between the upper clamp short handle 11 and the push-pull rod 8, and the first joint pin 7 horizontally penetrates through the upper clamp short handle 11 and the push-pull rod 8. The upper clamp short handle 11 and the push-pull rod 8 are movably connected through the first joint pin 7, so that when the air cylinder 3 drives the push-pull rod 8 to perform left-right translation inside the lower clamp seat 2, the upper clamp short handle 11 can be swing-tractioned.
[0024] The upper plate 5 is provided with clamp limit pieces 13, and the clamp limit pieces 13 are vertically located at the front and rear ends of the upper plate 5. One end of the upper clamp 6 is located between the clamp limit pieces 13. Thus, when the upper clamp 6 clamps the material on the upper plate 5, it will not be displaced through the clamp limit pieces 13.
[0025] A connecting block 9 is arranged between the air cylinder 3 and the push-pull rod 8. One side of the bottom end of the connecting block 9 is connected to the push-pull rod 8, and one side of the top end of the connecting block 9 is connected to the air cylinder 3. Thus, when the air cylinder 3 drives the connecting block 9 to move back and forth, the push-pull rod 8 can be driven to perform left-right translation inside the lower clamp seat 2, so as to drive the upper clamp 6 to swing subsequently.
[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
