Pair of self-adaptive labor-saving crimping pliers

Abstract

The invention relates to a pair of self-adaptive labor-saving crimping pliers, which comprise a long handle, a movable handle and a pliers head arranged at one end of the long handle and one end of the movable handle. One end of the long handle is forked, and a connecting arm and an elastic supporting arm are formed at the end of the long handle. The connecting arm is rotationally arranged on thepliers head and forms linkage fit between the long handle and the pliers head. One end of the movable handle is forked, and a movable connecting arm and an elastic driving arm are arranged at the end.The movable connecting arm is rotationally arranged on the pliers head and forms linkage fit between the movable handle and the pliers head, the elastic driving arm is rotationally arranged on the elastic supporting arm and forms rotating connection fit between the movable handle and the long handle, the elastic supporting arm is provided with a limiting portion, and a tension spring is arrangedbetween the limiting portion and the movable handle. A shaft sleeve matched with pressing teeth is arranged on a pin shaft. The pair of self-adaptive labor-saving crimping pliers has the advantages ofbeing simple in structure, stable and reliable in performance and convenient to operate.

Description

technical field [0001] The invention relates to a wire crimping pliers, in particular to an adaptive labor-saving crimping pliers. Background technique [0002] Crimping pliers are tools used to crimp terminals and wires. Different crimping pliers are selected for crimping according to different terminals. The existing crimping pliers for crimping tubular terminals generally do not have self-adaptive function, and need to adjust the size according to the size of the terminal before crimping. The operation is cumbersome, the application area is narrow, and it is not universal. The manual wire crimping pliers include a pliers head for crimping terminals, a long handle, a moving handle, and a transmission mechanism arranged between the long handle and the moving handle. The structural design of the transmission mechanism of the pliers head of the existing wire crimping pliers is different Reasonable, the structure of the transmission mechanism is relatively complicated, result...

Problems solved by technology

The existing crimping pliers for crimping tubular terminals generally do not have self-adaptive function, and need to adjust the size according to the size of the terminal before crimping. The operation is cumbersome, the applicable area is narrow, and it is not universal.

The manual wire crimping pliers include a pliers head for crimping terminals, a long handle, a moving handle, and a transmission mechanism arranged between the long handle and the moving handle. The structural design of the transmission mechanism of the pliers head of the existing wire crimping pliers is different Reasonable, the structure of the transmission mechanism is more complicated, resulting in a larger volume of the entire crimping tool, and the operator is more laborious when using it, which increases the labor intensity of the operator

And this crimping tool also has the defects of complex structure, unreliable performance and convenient operation
