Description

Pliers

The invention relates to a clamp.

In auto repair related fields, there is often a need to clamp ring parts. Because the clamp will become the neck after the clamp, in order to accommodate a larger head, the clamps used to clamp are often two The front end of the clamping jaw is additionally protruding to form a clamping edge, so that when the clamping edges are in contact with each other, there is still a gap between the two clamping jaws to accommodate the head of the clamped part.

The patents TW D193158 and TW D189624 disclose the typical structure of this type of pliers, which includes a main handle and a pivot that are pivoted to each other. The front ends of the main handle and the pivot are respectively equipped with clamping blocks, and the front edge of the clamping block protrudes. A clamping edge is formed, and when the main handle and the pivot handle are relatively pivoted, the clamping edges can be close to each other to clamp the parts.

However, the clamping edge of this type of pliers is located on the side of the pliers, that is to say, the pliers must be perpendicular to the clamped place to perform the clamping operation. If there is a lack of operating space, the clamping operation will not be possible. It is difficult to apply force. At this time, it is necessary to use another clamp with clamping edges in different directions to perform the operation, which is very inconvenient, and the cost of preparing multiple tools is high, and it is also not conducive to storage.

The main purpose of the present invention is to provide a pliers that can easily switch the position and direction of the clamping portion, and can operate the clamping action in different holding directions.

To achieve the above objective, the present invention provides a pliers including a main handle, a pivot handle and two clamping blocks.
