The first feeding space and the second feeding space are the spaces where the pushing structure 3 is located after the first feeding step and after the second feeding step.
When the pliers are used, the driving handle 4 is pulled, so that the first feeding mechanism 5 drives the pushing structure 3 to move until the pushing structure 3 is positioned in the first feeding space, the pliers head 1 is in a semi-closed state, and the driving handle 4 rotates by about 15 degrees. The driving handle 4 is pulled continuously, when the driving handle 4 rotates about 25 degrees, the binding clip 1 is opened again, and then the driving handle 4 is pulled, so that the second feeding mechanism 6 drives the pushing mechanism 3 to move until the pushing mechanism 3 is positioned in the second feeding space, at this time, the binding clip 1 is in a clamping state, and at this time, the driving handle 4 rotates about 42 degrees. Therefore, the invention realizes two-step clamping of the binding clip 1 by using the first feeding mechanism 5 and the second feeding mechanism 6, the first feeding mechanism 5 finishes the first step to clamp the binding clip 1 to a certain opening degree, thus the amplitude of the automatic flicking action of the tissue clip can be effectively reduced when the tissue clip is pushed out, and then the second feeding mechanism 6 is used for slowly clamping to be completely closed, so the invention is more suitable for the tissue clip which can flick out automatically when being pushed out.
Specifically, the first feeding mechanism 5 is located at the front end of the second feeding mechanism 6, and the driving handle 4 is rotated, so that the first feeding mechanism 5 pushes the propelling structure 3 before the second feeding mechanism 6.

In use, the drive handle 4 is rotated to press the first push block 51 against the first push assembly 52 to push the push structure 3. After a certain angle, due to the forward movement of the pushing structure 3 and the change of the angle of the first pushing block 51, the distance between the first pushing block 51 and the first pushing assembly 52 is increased, the first pushing block 51 and the first pushing assembly 52 are separated from each other, and the feeding in the first step is completed.
Specifically, the first pushing assembly 52 includes a mounting base 53 fixedly connected to the pushing structure 3 and a first force-bearing pushing block 54, one end of the first force-bearing pushing block 54 is rotatably connected to the mounting base 53, the other end of the first force-bearing pushing block extends in a direction close to the driving handle 4, and the torsion spring 55 is sleeved on the first force-bearing pushing block 54. Therefore, when a large force is applied, the first stressed pushing block 54 can be turned over, so that after the clamping is completed, the first pushing block 51 returns to the rear end of the first stressed pushing block 54 from the front end of the first stressed pushing block 54.

When the mistaken clamping is to be prevented, the locking bolt 73 extends to a position between the second pushing block 61 and the second stressed pushing block 62, and when the driving handle 4 is rotated, the second pushing block 61 is pressed on the bottom surface of the locking bolt 73 and is blocked, so that the second stressed pushing block 62 cannot be pushed. When the operation needs to be performed normally in the operation process, the operation button 71 is pressed, the operation button 71 drives the swing arm 75 to swing, one end of the swing arm 75 is pressed on the sliding block 76, the sliding block 76 drives the bolt 73 to synchronously slide away from the second feeding mechanism 6, and at the moment, the return spring 77 is compressed.
