Description

Technical Field

[0001] The utility model relates to the technical field of working tools, and more specifically, to a multi-functional pliers. Background Art

[0002] As a manual tool widely used in daily life and industrial production, pliers have various different functions due to the diversity of the shapes of their jaws. When performing various repair, assembly or disassembly operations, people often need to prepare and use various types of pliers according to different requirements. For example, long-nose pliers are suitable for delicate operations, while bench vices are suitable for tightening wire. Therefore, during normal operations, in order to handle various different tasks, people often need to carry multiple pliers for emergencies.

[0003] However, when using pliers for operations, in addition to the pliers themselves, other auxiliary tools are also required to cooperate to ensure the smooth progress of the work. For example, a screwdriver is used to tighten or loosen screws, a voltage tester is used to detect whether an electric circuit is energized, and a utility knife can be used to cut or trim materials. These auxiliary tools play an indispensable role in operations, enabling the pliers to exert their maximum effectiveness.

[0004] In the prior art, in order to facilitate the carrying of these tools, people usually use a tool belt that wraps around the waist. This belt can be equipped with multiple pockets and hanging rings for placing and fixing various tools, enabling operators to easily carry the required tools with them. However, although this carrying method improves the portability of the tools to a certain extent, its carrying space is still limited and cannot accommodate too many tools. In addition, when carrying a large number of tools, the weight of the belt will increase, imposing a burden on the operator and possibly affecting the flexibility and comfort of their movement. Therefore, how to improve the tools to save carrying space has become an urgent problem to be solved. Summary of the Invention

[0005] In view of the problem of large space occupation when carrying a large number of tools in the prior art, this solution provides a multi-functional pliers. In this solution, accommodation spaces are provided in the first pliers and the second plier handle to carry and place auxiliary tools, reducing the space occupied by the auxiliary tools.

[0006] To achieve the above object, the technical solution provided by the utility model is as follows:

[0007] A multi-functional pliers, comprising

[0008] A first plier handle;

[0009] A second plier handle, hinged to the front end of the first plier handle;

[0010] The jaw head is detachably connected to the hinge joint of the first jaw handle and the second jaw handle;

[0011] A receiving space is provided on the first jaw handle and / or the second jaw handle, and an auxiliary tool is detachably connected inside it.

[0012] The jaw head is detachably connected to the hinge joint of the first jaw handle and the second jaw handle, and the jaw head and the jaw handle can be separately separated and replaced. During operation, only one multi-functional pliers and several jaw heads need to be carried to achieve different types of jaw head operations, thus achieving the purpose of reducing the carrying weight. In addition, a receiving space is provided on the first jaw handle or the second jaw handle, and common auxiliary tools are stored in the receiving space. When in use, they can be directly taken out from the receiving space of the pliers, and the saved space can be used to carry more other tools.

[0013] In the multi-functional pliers of the present application, further, the first jaw handle includes a front connecting portion and a rear connecting portion connected end to end, the receiving space is arranged along the axial direction of the front connecting portion, the auxiliary tool is fixedly connected to the end of the rear connecting portion, and the auxiliary tool is adapted to the shape and size of the receiving space.

[0015] In the multi-functional pliers of the present application, further, the conductive column of the electric pen is inserted into the receiving space and contacts the conductive block in the receiving space, and the conductive block is electrically connected to the jaw head.

[0016] During the process of using the pliers, the current will sequentially pass through the jaw head, the conductive block and into the conductive column of the electric pen, and it will be shown on the handle of the electric pen whether there is power. Therefore, when the electric pen can be separated from the pliers, while the pliers are operating, it can be checked whether the jaw head is electrified, without switching back and forth, which is convenient for the operator to operate and also improves the operation efficiency.

[0017] In the multi-functional pliers of the present application, further, the conductive block includes a flashlight, a connecting plate and a spring piece. The connecting plate is fixedly connected to the end of the flashlight, and one end of the spring piece is fixedly connected to the connecting plate obliquely. When the jaw head is engaged into the jaw head receiving area, the marble is retracted into the channel under the extrusion of the jaw head. When the jaw head is engaged in place, the marble is extruded into the depression of the jaw head arm under the extrusion of the elastic member, realizing the fixation of the jaw head.

[0018] In the multi-functional pliers of the present application, further, the rear connecting part is engaged in the L-shaped groove on the outer side surface of the front connecting part to form the same shape as the second plier handle. An L-shaped groove is provided on the upper surface of the front connecting part, so that the front connecting part can penetrate through the entire length of the second plier handle, increasing the strength of the second plier handle and avoiding breakage during the application of force.

[0019] In the multi-functional pliers of the present application, further, a magnetic attraction structure is provided at the contact surface between the front connecting part and the rear connecting part, so that the front connecting part and the rear connecting part are magnetically connected. The magnetic attraction structure can ensure that when the front connecting part is connected to the rear connecting part, it can be tightly adsorbed, and can also be firmly connected without falling off when the two are not under force.

[0020] In the multi-functional pliers of the present application, further, a protrusion and a strip-shaped groove adapted to the protrusion are respectively provided at the contact surface between the front connecting part and the rear connecting part, and the protrusion and the strip-shaped groove are engaged to limit the dislocation of the rear connecting part. A protrusion and a strip-shaped groove adapted to the protrusion are respectively provided at the contact surface between the front connecting part and the rear connecting part, which can limit the dislocation of the handle along the direction perpendicular to the force application direction, facilitating the pliers to hold the handle tightly when under force.

[0021] In the multi-functional pliers of the present application, further, the auxiliary tool is completely built into the accommodating space, and the entrance of the accommodating space is clamped with a cover plate. The auxiliary tool is completely built into the accommodating space, which can prevent the auxiliary tool from being exposed outside and reduce the risk of the auxiliary tool detaching from the pliers. The cover plate can open and close the accommodating space, facilitating the taking and placing.

[0022] In the multi-functional pliers of the present application, further, the cover plate includes a first sealing plate and a second sealing plate connected end to end with the first sealing plate, and a buckle is fixed under the first sealing plate; reinforcing ribs are fixed on the first sealing plate and the second sealing plate. The cover plate includes a first sealing plate and a second sealing plate connected end to end with the first sealing plate, so that the first sealing plate and the second sealing plate can present an L shape, which can improve the strength of the cover plate and prevent it from being too soft. In addition, the reinforcing ribs can also improve the connection strength of the cover plate to a certain extent and prevent the first sealing plate and the second sealing plate from being too soft.

[0023] In the multi-functional pliers of the present application, further, the auxiliary tool includes an electric pen. The conductive column of the electric pen is inserted into the accommodating space and contacts the conductive block in the accommodating space, and the conductive block is electrically connected to the plier head; a window communicating with the accommodating space is provided on the first plier handle. Similarly, without detaching the electric pen from the pliers, while the pliers are operating, it can be checked whether the plier head is electrified without switching back and forth. The current will sequentially pass through the plier head, the conductive block and enter the conductive column of the electric pen, and it can be directly observed through the window whether the handle of the electric pen shows power on.

[0024] In the multi-functional pliers of the present application, further, channels are provided in both the first plier handle and the second plier handle, and the channels communicate with the accommodation area of the plier head. An elastic member and a ball are sequentially fixed in the channels, and the elastic member elastically presses on the ball. When the plier head is engaged into the plier head accommodation area, the ball retracts into the channel under the extrusion of the plier head. When the plier head is engaged in place, the ball is extruded by the elastic member into the recess of the plier head arm to achieve the fixation of the plier head.

[0025] In the multi-functional pliers of the present application, further, a spring is connected between the first plier handle and the second plier handle. The spring can provide a rebounding force for the separation of the first plier handle and the second plier handle.

[0026] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0027] The multi-functional pliers provided by the present utility model detachably connect the plier head to the hinge joint of the first plier handle and the second plier handle, and the plier head and the plier handle can be separately separated and replaced. During operation, only one multi-functional plier and several plier heads need to be carried to achieve different types of plier head operations, thus achieving the purpose of reducing the carrying weight.
