[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1As shown, a multi-purpose pliers with bidirectional adjustment and self-locking functions includes a pliers body, wherein the number of the pliers bodies is 2 and they are symmetrically arranged. The pliers bodies are connected by a connecting shaft 5, and the connecting shaft 5 is responsible for connecting and providing a support point for the rotation of the pliers body. The pliers body includes a connecting circular plate 2, and the connecting circular plate 2 has a large coverage area, which ensures the integrity and stability of the connection of the pliers body. The connecting shaft 5 is connected as a whole with the connecting circular plate 2 located at the bottom. When the bottom pliers body is rotated, the connecting shaft 5 will rotate with it. A limiting layer 6 is provided on the upper surface of the connecting circular plate 2 located at the top, and the limiting operation is realized by the limiting layer 6. A limiting stopper 8 is provided on the connecting shaft 5. When the limiting stopper 8 is moved, the limiting stopper 8 rotates with the connecting shaft 5 when the pliers body is pinched and released. When it moves to a certain position, it will hit the limiting layer 6 to limit the angle range of the rotation of the pliers body.

[0024] The following is a detailed description of the design of the above key components:

[0025] The pliers body also includes a pliers handle 1 and a pliers clamp 3. The pliers handle 1 is used to hold and operate the pliers body, and is convenient to grasp. The front side of the pliers handle 1 is connected to the connecting circular plate 2, and the front side of the connecting circular plate 2 is connected to the pliers clamp 3. The number of pliers handles 1, connecting circular plates 2 and pliers clamp 3 is set to 2 corresponding to the number of pliers bodies. The pliers handle 1 is designed to be in a shape that conforms to human ergonomics, which is convenient for the operator to grasp and operate the pliers body. The front end of the pliers handle 1 is connected to the connecting circular plate 2, and the pliers handle 1, the connecting circular plate 2 and the pliers clamp 3 are firmly connected. The pliers clamp 3 is closed by holding the pliers body tightly to achieve clamping, which is convenient for the operator to operate the two pliers bodies at the same time.

[0026] The limiting layer 6 is C-shaped and arranged on the surface of the connecting circular plate 2. The limiting layer 6 is designed to be C-shaped and fixed on the surface of the connecting circular plate 2, wherein the opening direction of the C-shape faces downward. Through the setting of the limiting layer 6, the movement range of the clamp handle 1 is limited in cooperation with the limiting block 8. The design of the limiting layer 6 is simple and practical, and the limiting function is effectively completed.

[0027] The limit stopper 8 is arranged on the connecting shaft 5 through the locking shaft 7. The limit stopper 8 is arranged on the connecting shaft 5 through the locking shaft 7, and is used to limit the movement range of the clamp 3, and has a self-locking function, which can be locked and fixed at a certain position to prevent the clamp 3 from accidentally moving during operation, thereby improving the safety of operation.

[0028] A spring 4 is arranged inside the clamp handle 1, and the spring 4 is connected to the inside of another clamp handle 1. The spring 4 can limit the clamp handles 1 from being close to each other, so that the clamp 3 will not be in a clamping state for a long time.

[0029] The limiting layer 6 is fixed on the connecting circular plate 2 by a cross bolt 9. The cross bolt 9 ensures that the limiting layer 6 is fixed firmly and reliably. Through the design of the cross bolt 9, the limiting layer 6 can be easily installed and removed, and the limiting layer 6 with different opening models can be selected according to needs, thereby improving adaptability.

[0030] A multi-purpose pliers with two-way adjustment and self-locking functions, which has two functions of opening or clamping and can be freely switched. By adjusting the position of the limit stop block 8, when clamping or loosening the pliers handle 1, it has the function of limiting the rotation of the pliers body in both directions, reducing or eliminating loosening, and playing a good reverse rebound effect. It can reduce the physical strength of workers or operators, reduce the difficulty of operation, enhance the operation stability, and eliminate the occurrence of errors such as the flying off of the clamping parts from the source, avoid other derivative accidents caused by this, and maximize the safety of maintenance. It is suitable for various maintenance operations, improves work efficiency, reduces labor intensity and operation difficulty, and can effectively avoid other accidents.

[0031] The standard parts used in the utility model can all be purchased from the market, special-shaped parts can be customized according to the description in the specification and the drawings, the specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art, and the machinery, parts and equipment all adopt conventional models in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
