[0019] 1. In this utility model, the mounting base, clamp arms, drive base, and transmission rod are combined to form a four-bar linkage. During use, the drive motor drives the two clamp arms to rotate relative to the mounting base through the four-bar linkage. The four-bar linkage has a simple structure, good stability, and high reliability. The production cost of this crimping clamp is low, and it is easy to assemble and produce.

[0020] 2. The detachable first and second clamping parts in this utility model help extend the service life of the clamp arms and allow users to easily replace them as needed, enabling the crimping pliers to process different wires. This makes it convenient for users to use. The positioning protrusions and positioning grooves facilitate the positioning and installation of the first and second clamping parts, making it easy to quickly assemble and use the crimping pliers. The crimping grooves and crimping protrusions of different specifications make it easy for the crimping pliers to process wires of different specifications. When crimping wires, the spacer grooves can form a stepped structure at the wire connection, which is beneficial to the stable connection of the wires.
[0021] 3. The movable groove in this utility model facilitates flexible control of the control component. When the control component is accidentally touched, it can rotate relative to the control component without triggering the start switch, thus preventing the crimping pliers from opening accidentally and improving the safety of the crimping pliers.

The first limit switch and the second limit switch facilitate the automatic stop or reverse movement of the drive seat when it reaches the limit position, preventing damage to the drive seat due to excessive force during use and extending the service life of the crimping pliers.
[0022] 4. The first and second driving components, which are slidably connected to the mounting base respectively, facilitate the processing and production of the driving base. This structure allows the control component to directly drive the clamp arm, enabling the crimping clamp to function normally even when there is no power. Furthermore, this structure allows for flexible combination of first and second driving components of different specifications, reducing production costs. The arrangement of the lever and driving rod facilitates the flexible assembly and use of the control component. This structure also reduces the movement of the lever when the driving rod slides along the movable groove, facilitating the triggering of the start switch by the lever. The arrangement of the first and second triggering parts allows for the triggering of the first and second limit switches respectively when the first and second driving components are separated, facilitating the use and control of the crimping clamp.
[0023] 5. The lubrication seat in this utility model helps to reduce friction during the movement of the first driving component and reduce noise during the use of the crimping pliers, which helps to extend the service life of the first driving component; the planetary gear set has a compact structure, which helps to reduce the size of the crimping pliers, and the planetary gear set has high transmission efficiency, which can reduce energy loss and improve the efficiency of the system.

Two transmission rods 5 are rotatably mounted on the drive seat 4, and each transmission rod 5 is rotatably connected to one of the clamping arms 2. The mounting base 1 and the clamping arms... 2. The drive seat 4 and the transmission rod 5 are combined to form a four-bar linkage. The drive motor 3 can control the output shaft 32 to rotate and make the drive seat 4 slide relative to the mounting seat 1. The mounting seat 1 can drive the clamp arms 2 to rotate relative to the mounting seat 1 through the transmission rod 5, so that the clamping parts on the two clamp arms 2 move closer or further apart. In this structure, the four-bar linkage is simple, stable, and reliable. The production cost of this crimping clamp is low and it is easy to assemble and produce. In addition, the torque output by the output shaft 32 can be increased through the reduction gear set 31, which is convenient to increase the force of the clamp arms 2 on the crimped items and is convenient for users to use.
[0041] Preferably, the reduction gear set 31 is a planetary gear set. The planetary gear set has a compact structure, which helps to reduce the size of the crimping pliers. In addition, the planetary gear set has high transmission efficiency, which can reduce energy loss and improve the efficiency of the system.
[0042] In this embodiment, the crimping clamp includes a housing 7, a mounting base 1 and a drive motor 3, all of which are disposed in the housing 7, and a battery pack 9 is detachably disposed on the housing 7.
[0043] The clamp arms 2 described in this invention include swing arms 21 rotatably connected to the mounting base 1. Each swing arm 21 of the two clamp arms 2 is detachably equipped with a first clamping member 22 and a second clamping member 23 for clamping items. The detachable first clamping member 22 and second clamping member 23 helps extend the service life of the clamp arms 2 and allows the user to easily replace the first clamping member 22 and second clamping member 23 as needed, enabling the crimping pliers to process different wires and facilitating user operation.
[0044] In this embodiment, both the first clamping member 22 and the second clamping member 23 are provided with positioning protrusions 221, and both clamping arms 2 are provided with positioning grooves 211 that are adapted to the positioning protrusions 221.

Releasing the control component 6, the first elastic element 63 can drive the control component 6 to slide along the movable groove 18. When the groove 18 is reset in the length direction, the control component 6 can trigger the emergency stop switch 81. The drive motor 3 drives the clamping parts on the two clamp arms 2 to move away from each other. The movable groove 18 facilitates the flexible control of the control component 6.
