[0002] Pliers are a kind of mechanical tool, which is often used in model making. They are used to cut the joints of plastic or metal, which is more time-saving and labor-saving than twisting by hand. Pliers are shaped like scissors, but the head is smaller and thicker than ordinary scissors, just like the back half of the pliers head. Pliers are one of the hydraulic shears used in emergency rescue. Pliers are made of aerospace high-strength lightweight alloy, with light weight, strong shearing ability, short opening and closing time, and accelerate the rescue process. They are used in highway, railway and other traffic accident rescue, earthquake disaster and building collapse rescue, air and sea accident rescue, and convert small external force (such as hand force applied to the pliers arm) into large power, so that the pliers can effectively clamp or shear the plate.

[0003] When the existing plate shearing pliers are used, a part of the plate will fall directly to the ground after being cut off, and if you are not careful, the plate will fall down and hit your feet;

[0004] Therefore, it is particularly important to design a plate shearing pliers to solve the above technical defects and improve the practicability of the overall plate shearing pliers. Utility Model Content

[0005] The purpose of the utility model is to provide a plate shearing pliers, which can first limit and fix the plate through an L-shaped limit block, and then shear the plate through a first shearing head and a second shearing head.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A plate shearing pliers, comprising a first shearing head 1 and a second shearing head 2, wherein the first shearing head 1 and the second shearing head 2 are respectively connected with a first handle 5 and a second handle 6 via a first connecting plate 3 and a second connecting plate 4, and a shearing assembly 7 is provided between the first connecting plate 3 and the second connecting plate 4;

[0025] Among them, a plurality of L-shaped limit blocks 101 are fixedly connected to one side of the first shearing head 1 and the second shearing head 2, and the first shearing head 1, the second shearing head 2 and the plurality of L-shaped limit blocks 101 are symmetrically designed in structure;

[0026] The outer sides of the first handle 5 and the second handle 6 are both covered with a layer of anti-skid cover 501 made of rubber material, and the outer sides of the first handle 5 and the second handle 6 are both fixedly connected with anti-skid protrusions 502;

[0027] Specifically, when the user presses the first handle 5 and the second handle 6 with his hands, the first handle 5 and the second handle 6 are brought close to each other, and then the first handle 5 drives the first cutting head 1 to move through the first connecting plate 3, and the second handle 6 drives the second cutting head 2 to move through the second connecting plate 4, and the first cutting head 1 and the second cutting head 2 are brought close to each other through the cutting assembly 7, and the plate is cut by the first cutting head 1 and the second cutting head 2. At the same time, the L-shaped limit blocks 101 inside the first cutting head 1 and the second cutting head 2 limit the plate to prevent the plate from falling, and the anti-slip sleeves 501 and the anti-slip protrusions 502 on the outside of the first handle 5 and the second handle 6 increase the friction between the user's palm and the first handle 5 and the second handle 6.

[0028] Also, see Figure 1-Figure 3 , a shear assembly 7 is provided between the first connecting plate 3 and the second connecting plate 4;

[0029] The shearing assembly 7 is used to control the opening and closing between the first shearing head 1 and the second shearing head 2. The specific structure of the shearing assembly 7 is as follows:

[0030] The shearing assembly 7 includes a rotating ring 701, a connecting block 702, a connecting frame 703, a sliding block 704, a first connecting seat 705, a second connecting seat 706, a first connecting ring 707, a first connecting column 708, a second connecting column 710 and a moving ring 711. The rotating ring 701 is rotatably connected between the first connecting plate 3 and the second connecting plate 4. The rotating ring 701 is connected to the connecting frame 703 through the connecting block 702. The connecting frame 703 is respectively connected to the first shearing head 1 and the second shearing head 2 through two sets of sliding blocks 704. The first connecting seat 705 is fixedly connected to the outer side of the first shearing head 1 and the side close to the first handle 5. A second connecting seat 706 is fixedly connected to the outside of the second cutting head 2 and located on the side close to the second handle 6. The first connecting seat 705 is rotatably connected to the first connecting column 708 through the first connecting ring 707. The second connecting seat 706 is rotatably connected to the second connecting column 710 through the second connecting ring 709. The first connecting column 708 and the second connecting column 710 are rotatably connected to the connecting frame 703 through the moving ring 711. The connecting frame 703 is designed in a T-shaped structure. Sliding grooves are provided inside the connecting frame 703 and at positions corresponding to the sliding block 704, the first connecting ring 707, the second connecting ring 709 and the moving ring 711.

[0031] Specifically, the opening and closing of the first shearing head 1 and the second shearing head 2 are controlled by the shearing assembly 7. When the user presses the first handle 5 and the second handle 6 by hand, the first connecting plate 3 and the second connecting plate 4 are rotated through the rotating ring 701 at the same time. The first handle 5 and the second handle 6 control the first shearing head 1 and the second shearing head 2 to approach each other through the first connecting plate 3 and the second connecting plate 4, so that the first shearing head 1 drives the first connecting ring 707 to move through the first connecting seat 705, and the second shearing head 2 drives the second connecting ring 709 to move through the second connecting seat 706, and then the first connecting column 708 and the second connecting column 710 are respectively driven to move through the first connecting ring 707 and the second connecting ring 709, so that the first connecting column 708 and the second connecting column 710 are rotated through the moving ring 711, and then the moving ring 711 is moved on the connecting frame 703, and at the same time, the first shearing head 1 and the second shearing head 2 are respectively moved on the connecting frame 703 through the two groups of connecting blocks 702, and at the same time, the rotating ring 701 is moved on the connecting frame 703 through the sliding block 704.

[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the user presses the first handle 5 and the second handle 6 with his hands, the first handle 5 and the second handle 6 are brought close to each other, and then the first handle 5 drives the first cutting head 1 to move through the first connecting plate 3, and the second handle 6 drives the second cutting head 2 to move through the second connecting plate 4, and the first cutting head 1 and the second cutting head 2 are brought close to each other through the cutting assembly 7, and the plate is cut by the first cutting head 1 and the second cutting head 2. At the same time, the L-shaped limit blocks 101 inside the first cutting head 1 and the second cutting head 2 limit the plate to prevent the plate from falling. The anti-slip sleeve 501 and the anti-slip protrusion 502 on the outside of the first handle 5 and the second handle 6 increase the friction between the user's palm and the first handle 5 and the second handle 6. Compared with the existing plate cutting pliers, the utility model can improve the overall practicality of the plate cutting pliers through design.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
