Problems solved by technology

[0003] Existing circlip pliers are designed with a single pliers head, either an inner caliper or an outer caliper; while in equipment maintenance, both an inner caliper and an outer caliper may be required. In order to avoid missing tools, it is usually necessary to insert The calipers and outer calipers are carried at the same time, causing inconvenience in carrying
[0004] The Chinese patent literature records a kind of snap ring pliers, the application number is 2017211293255, which can be switched between the inner calipers and the outer calipers through the detachable assembly structure, but the structure of the snap ring pliers is complicated, and the There are many parts, the disassembly and assembly are complicated, and it is easy to cause the loss of parts

Abstract

The invention discloses a dual-purpose circlip pliers, comprising a first pliers body and a second pliers body, the first pliers body includes a first pliers head, a first connecting part and a first handle, and the first handle faces away from the first The direction of the pliers head is set on the first connecting part; the second pliers body includes a second pliers head, a second connecting part and a second handle, and the first connecting part and the second connecting part are rotatably connected by a hinge shaft; it is characterized in that , an inner card mounting hole and an outer card mounting hole are arranged on the side of the second connecting part away from the second pliers head, and the second handle is detachably mounted on the inner card mounting hole or the outer card mounting hole; the inner card mounting hole and the outer card mounting hole are detachably installed The card mounting holes are distributed on both sides of the first handle along the circumferential direction of the hinge shaft, so that the inner card mounting hole and the second clamp head are respectively located on both sides of the first handle, and the outer card mounting hole and the second clamp head are located on the first handle. the same side of a handle. The invention has the advantages of simple and ingenious structural design, few disassembly and assembly parts, convenient and quick disassembly and assembly, and easy portability.

Description

technical field [0001] The invention relates to the technical field of maintenance tools, in particular to a dual-purpose snap ring pliers. Background technique [0002] Circlip pliers are divided into hole circlip pliers (also known as inner circlip pliers) and shaft circlip pliers (also known as outer circlip pliers). It is a special tool used to install the inner and outer circlips. It belongs to needle-nose pliers in appearance. The hole uses the circlip pliers to press the two ends of the hole with the circlip to disassemble it. The shaft uses the circlip pliers Spread the shaft with the two ends of the circlip to disassemble it. [0003] Existing circlip pliers are designed with a single pliers head, either an inner caliper or an outer caliper; while in equipment maintenance, both an inner caliper and an outer caliper may be required. In order to avoid missing tools, it is usually necessary to insert The caliper and the outer caliper are carried at the same time, the...
