Description

Technical Field

[0001] The utility model relates to the technical field of wire crimping pliers, in particular to a wire crimping pliers with replaceable jaws. Background Art

[0002] Crimping pliers are tools used to press the connection between wires and terminals. Common telephone line connectors, network cable connectors, and connectors between wires and devices are all crimped with crimping pliers. Since there are many types and models of wiring, corresponding crimping pliers need to be matched. For electricians, carrying a large number of crimping pliers of different models will not only waste manpower, but also may cause the loss of crimping pliers. Therefore, the use of crimping pliers with replaceable jaws is undoubtedly the best technical solution.

[0003] In the existing crimping pliers with replaceable jaws, the jaws are placed on the clamping end of the crimping pliers body, and the positioning is completed for clamping. However, after using such crimping pliers for a period of time, the jaws and the crimping pliers body are easily adhered or stuck together, and are not easy to disassemble. It is often necessary to use tools to remove the jaws, which is not only time-consuming and labor-intensive, but also may cause damage to the jaws. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a wire crimping pliers with replaceable jaws.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A crimping pliers with replaceable jaws, comprising a crimping pliers body and jaws, wherein one end of the crimping pliers body is a handle, and the other end is a clamping end, a groove is provided at the port of the clamping end, at least one spring is installed at the inner end of the groove, the jaws are inserted into the groove, and the inner end of the jaws and the spring form a conflict, a rotatable shaft is provided in the groove, a rotating cap is provided at one end of the shaft and is placed outside the clamping end, a socket is provided on the jaws, a circular hole is provided at the bottom of the socket, an elliptical locking block is provided at the position of the shaft corresponding to the socket, the minimum diameter of the locking block is smaller than the diameter of the socket, and the maximum diameter of the locking block is larger than the diameter of the socket but smaller than the diameter of the circular hole.

[0007] Preferably, the spring sheet is in a "C" shape, and a flat surface is provided at one end of the spring sheet close to the jaws.

[0008] Preferably, a limiting groove having a shape corresponding to that of the spring sheet is provided at the bottom of the groove, the spring sheet is placed in the limiting groove, and one end of the spring sheet having a flat surface is placed outside the limiting groove.

[0009] Preferably, a slot is provided in the limiting groove, and the other end of the spring piece opposite to the one provided with the plane is embedded in the slot.

[0010] Preferably, the spring sheet is a metal spring sheet.

[0011] Due to the adoption of the above scheme, the utility model directly inserts the jaws into the groove, and through the rotation of the shaft rod, the elliptical cylindrical locking block on the shaft rod is locked with the circular hole, thereby meeting the design requirements for the replacement of the jaws. At the same time, combined with the spring sheet, a force is provided to push the jaws outward all the time, which can provide a tightening force when the jaws are locked to avoid a loose feeling, and the jaws can be directly ejected after being disengaged, thereby facilitating and quickly replacing the jaws.

[0019] like Figures 1 to 3 As shown, a crimping pliers with replaceable jaws provided in this embodiment comprises a crimping pliers body 1 and a jaw 2, wherein one end of the crimping pliers body 1 is a handle 11, and the other end is a clamping end 12, a groove 13 is provided at the port of the clamping end 12, at least one spring 14 is installed at the inner end of the groove 13, and the spring 14 is a metal spring, the jaw 2 is inserted into the groove 13, and the inner end of the jaw 2 forms a conflict with the spring 14, a rotatable shaft 15 is provided in the groove 13, a rotating cap 16 is provided at one end of the shaft 15 and is placed outside the clamping end 12, a socket 21 is provided on the jaw 2, a circular hole 22 is provided at the bottom of the socket 21, an elliptical locking block 17 is provided at the position of the shaft 15 corresponding to the socket 21, the minimum diameter of the locking block 17 is smaller than the diameter of the socket 21, and the maximum diameter of the locking block 17 is larger than the diameter of the socket 21 but smaller than the diameter of the circular hole 22.

[0020] The present embodiment mainly inserts the jaws 2 directly into the grooves 13, and rotates the shaft 15 to lock the elliptical locking block 17 on the shaft 15 with the circular hole 22, thereby meeting the design requirements for replacement of the jaws 2. At the same time, the spring 14 is combined to provide a force to push the jaws 2 outward, which can provide a tightening force when the jaws 2 are locked to avoid a loose feeling, and can also directly pop out the jaws 2 after being disengaged, thereby facilitating and quickly replacing the jaws 2.

[0021] In specific operation, when the jaw 2 needs to be installed, the jaw 2 is selected, and then the inner end of the jaw 2 is inserted along the groove 13, and the smallest diameter surface of the locking block 17 is aligned with the socket 21, so that the socket 21 can smoothly form a docking with the locking block 17. After being inserted to the innermost position, the spring piece 14 is compressed, and the locking block 17 just enters the circular hole 22, and then the external force acts on the rotating cap 16 to rotate the shaft 15, and the locking block 17 also rotates in the circular hole 22. After the rotation, the longest diameter surface of the locking block 17 corresponds to the socket 21, so that the locking block 17 will not be able to detach from the socket 21, and combined with the elastic force of the spring piece 14, the locking block 17 is tightly attached to the inner wall surface of the circular hole 22, thereby completing the installation of the jaw 2. When it is necessary to replace another jaw 2 (different jaws 2 only have the jaw surfaces for crimping different from each other, and other parts need to be consistent), only external force is needed to act on the rotating cap 16 to rotate the shaft 15, generally 90°. At this time, the locking block 17 will dock with the socket 21 with the smallest diameter surface again. Under the elastic force of the spring piece 14, the jaw 2 will be ejected, so that the jaw 2 can be directly grasped. According to the above steps for installing the jaw 2, the required jaw 2 can be installed again. The overall installation is very simple and convenient.

[0022] Furthermore, with regard to the shape of the spring piece 14, the present embodiment specifically makes the spring piece 14 into a "C" shape, and the spring piece 14 is provided with a plane 141 at one end close to the jaw 2. The design of the plane enables the spring piece to better contact with the inner end of the jaw 2 to ensure sufficient contact.

[0023] Furthermore, in order to prevent the spring piece 14 from being separated from the groove 13 during the deformation process, a limiting groove 131 having a shape corresponding to the shape of the spring piece 14 is provided at the bottom of the groove 13 of the present embodiment, and the spring piece 14 is placed in the limiting groove 131, and one end of the spring piece 14 provided with the plane 141 is placed outside the limiting groove 131. In this way, the limiting groove 131 can provide a limiting effect on the spring piece 14, and in order to ensure that the spring piece 14 will not be separated, a slot 132 is provided in the limiting groove 131, and the other end of the spring piece 14 relative to the plane 141 is embedded in the slot 132. With this design, the stability of the installation of the spring piece 14 can be guaranteed.

[0024] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
