Between the portion 321 and the second pivot portion 322, the elastic member 36 is different from the end of the second clip 32 and is connected between the two ends of the first grip 21. The elastic member 36 is also the second clip. The cymbal 32 and the first grip 21 provide a pulling force, and the elastic member 36 is a tension spring in this embodiment.

The second holder 30 further includes a release member 37 pivotally disposed on the second handle 31, and the release member 37 is located on the top handle 33 and the second handle 31. Between ends 312.

Please refer to FIG. 6 again, which is a use state diagram of the pliers for quickly adjusting the clamping force of the present invention. When the pliers 10 are gripping the object, the pivoting effect of the pivoting member 34 on the first gripper 20 and the second collet 32 can be achieved.

When the pliers 10 clamps the object, the second clamping jaw 32 clamps the object and is also subjected to a reaction force to form a positive pressure. The second clamping jaw 32 has a specific friction coefficient with the object when the user When the pliers are turned, the second clamping jaw 32 forms a frictional force with the object, and the frictional force acting on the second clamping jaw 32 drives the second clamping jaw 32 to move inwardly adjacent to one side of the object. The structure of the first holder 20 and the second clamping frame 32 is pivoted by the pivoting member 34, and the pivoting member 34 is pivotable relative to the first holder 20, thereby enabling the second clamping member The opening between the 32 and the first jaw 22 is further reduced, and the clamping force of the forceps can be raised to continue the above trend. After the clamping force is increased, the positive pressure of the second jaw 32 is increased, and the friction is increased. The force will also increase, eventually forming a cycle as described above, resulting in a tighter grip. The angle A in the present embodiment is in the range of 70 degrees or more and 90 degrees or less. When the angle A is the above angle, the effect of the pinch 10 is more optimal.

As far as the above is concerned, it can be concluded that the present invention has the following advantages:

1. The pliers of the present invention which are more tightly clamped, wherein the pliers comprise a first gripper and a second gripper, the first gripper comprising a first grip, a first gripper and An adjusting member, the first handle is provided with a connecting end and a holding end different from the connecting end, the first clip is fixedly connected to the connecting end of the first grip, and the first clip is adjacent to the A first clamping portion is disposed between one end of the first handle and an end different from the first handle, and the adjusting member is screwed to the holding end of the first handle, the second The holder includes a second handle, a second clamp, a top member and a pivot member, the second handle is provided with a connecting end and a holding end different from the connecting end, the first A first pivot portion and a second pivot portion are disposed at one end of the second clamp, and the first pivot portion of the second clamp is pivotally connected to the connection end of the second handle, the second a second clamping portion is disposed between the end of the clamping jaw adjacent to the second grip to the end different from the second grip, the second The first clamping portion and the first clamping portion are opposite to each other, and a first virtual reference line is disposed between the first clamping portion and the second clamping portion, and one end of the top member is pivotally disposed on the second handle Between the two ends, the top member is different from the end of the second handle against the adjusting member, the pivot member includes a first pivot portion and a second pivot portion, and the first pivot of the pivot member a second pivot portion pivotally disposed on the second clamp, the second pivot portion of the pivot member being pivoted to the first holder, the pivot member having a second virtual reference line, the second virtual reference line The first virtual reference line intersects the second virtual reference line and forms an angle therebetween by a pivot center of the first pivot portion of the pivot member and a pivot center of the second pivot portion of the pivot member.
