Description

Improved chuck structure

The present invention belongs to the technical field related to hand tools, especially refers to an improvement of the chuck structure.

According to the press, the pipe joints that connect two pipe fittings in automobile parts are often located in narrow spaces (such as engine rooms), or in the narrow gaps of various parts and equipment, so special clamping tools are often used in conjunction with them. operate.

For example, Chinese Patent No. I611877 "tool for dismantling pipe joints" is a special dismantling tool designed for specific pipe joints. The two clamping pieces are made to approach each other, so as to form clamping for the fasteners on both sides of the pipe joint, so as to achieve the purpose of releasing the pipe piece from the pipe joint.

Although the prior art can achieve the expected benefits of clamping the pipe joint, its structure has the following defects:

1. The clamping position cannot be determined: each clamping member of the prior art controls the two clamping members to be in the clamping state or the release state through displacement (submerged into the box body), so the clamping point is not the initial position of each clamping member. Instead, the aligned positions will be offset, so that the user needs to adjust the position several times to properly clamp the fasteners on both sides of the pipe joint.

2. Unable to perform blind disassembly: It is well known that the position of the pipe joint in the car may only be seen from a certain angle during the disassembly process, but when the clip is aligned with the pipe joint, it cannot be seen directly (you can touch it), a However, when the clamping point is displaced, the user cannot operate independently and safely, and needs the assistance of other people to watch.

Dispersion of the acting force: When the controller exerts force on the two clamping pieces, the clamping pieces and the box body form friction, which consumes the acting force and causes the components to wear.

In order to overcome the above-mentioned deficiencies in the structure, the industry has also proposed innovative designs, such as my country's M595023 "pipe joint dismantling tool" patent, which aims to improve the deficiencies in the previous case. However, although the patent M595023 can solve the deficiencies of the prior art, there are still imperfections; for example, during the recovery process of the elastic body (24) of the controller (20) in its structure, there is no Due to the restrained structure design, it is impossible to form a balanced distribution of the left and right clip bodies (12, 13), so the part of the left and right clip bodies (12, 13) protruding from the opening (116) of the box body (11) will Unpredictable left or right deflection is formed.

In view of the problems and deficiencies of the prior art, the main purpose of this creation is to provide an improvement in the chuck structure, and to solve the deficiencies of the prior art through the innovative design of the structure.

According to the above purpose of this creation, an improved chuck structure is proposed, which includes a box body, a left chuck body, a right chuck body, a left connecting rod, a right connecting rod, and a controller. The box system is composed of first and second shells, and a first and second guide parts are respectively formed on the first and second shells. The left and right clip bodies are pivotally connected to each other and assembled on the box body. One ends of the left and right connecting rods are pivotally connected to the left and right clamping bodies. The controller is pivotally connected with the same ends of the left and right connecting rods away from the left and right clamping bodies, and is slidably arranged on the first and second guiding parts. With the composition of the above components, the left and right connecting rods are pulled to move along the first and second guide parts by pulling the controller, and the left and right clamping bodies are synchronously connected to clamp or loosen the pipe joint, so as to achieve the separation of the pipe joint and the pipe fitting. .
