When the head of the pliers is in a closed position, the shearing blade of the upper jaw is positioned in the channel of the lower jaw.

[0004] The disadvantages of the existing patents are that when the existing shearing tools apply a large shearing force to the objects being sheared, there is a problem that the objects being sheared are ejected and fly around, and there are certain safety hazards during the operation process.

The buffer 2 that is relatively opened and closed clamps the sheared object through the clamping surface 2.1, so that the sheared object can be clamped between the two relatively opened and closed buffers 2 before and after being sheared, thereby preventing the sheared object from being ejected and flying around when the shearing tool applies a large shearing force to the sheared object, causing harm to the operator.

A mounting groove 1.2 is provided on the side wall of the clamping part 1, and the buffer 2 is fixed in the mounting groove 1.2 by a locking member 3 or glued in the mounting groove 1.2. The mounting groove 1.2 is located on the side wall of the clamping part 1, and the buffer 2 is fixed in the mounting groove 1.2 by a locking member 3 or glued in the mounting groove 1.2, so that the buffer 2 can be stably fixed in the mounting groove 1.2. The provision of the mounting groove 1.2 facilitates the installation and positioning of the buffer 2 on the one hand, and prevents the buffer 2 from increasing the thickness of the clamping part 1 on the other hand. The outer wall of the buffer member 2 is flush with the outer wall of the corresponding clamping portion 1, so that the buffer member 2 and the surface of the clamping portion 1 can be smoothly connected.

[0041] In order to prevent the buffer 2 from deforming when clamping the sheared object and affecting the shearing edge 1.1, a gap is provided between the buffer 2 and the shearing edge 1.1 on the corresponding clamping part 1.

The cavity 4 prevents the debris generated during the shearing process of the sheared object from being stuck between the buffer 2 and the shearing blade 1.1, causing the shearing blades 1.1 to be stuck or the buffer 2 to be deformed, resulting in reduced shearing performance. The cavity 4 can temporarily transfer the debris generated during the shearing process to prevent the debris from causing the shearing performance of the shearing blade 1.1 to be reduced.

Figure 5 As shown, a gap is provided between the buffer 2 and the shearing blade 1.1 on the corresponding clamping part 1. This prevents the buffer 2 from deforming and affecting the shearing blade 1.1 when clamping the object to be sheared. The buffer 2 is arranged along the extension direction of the shearing blade 1.1 on the corresponding clamping part 1. The buffer 2 is arranged along the extension direction of the shearing blade 1.1 on the corresponding clamping part 1, so that the shearing blade 1.1 can be sheared over the entire length range, so that the clamping range length of the buffer 2 is basically consistent with the length of the shearing blade 1.1, and the anti-splashing function can be achieved at any position of the shearing blade 1.1 of the clamping part 1.
