Description

Clamp spring pliers with inner and outer clamp rapid gear shifting and converting functions Technical Field The utility model relates to the technical field of manual hardware tools, in particular to a clamp spring clamp with an inner-outer clamp rapid gear shifting function. Background The clamp spring pliers are special tools for installing and detaching clamp springs (also called check rings or retaining rings). The snap spring is used as a fastener and is arranged in a shaft groove or a hole groove of the component so as to restrain the axial movement of the component. The clamp spring pliers are special tools for installing and detaching clamp springs, and belong to the sharp-nose pliers in appearance, and pliers heads can be in the forms of inner straight, outer straight, inner bending, outer bending and the like. The clamp spring pliers are mainly divided into an outer clamp spring pliers and an inner clamp spring pliers. The outer clamp spring pliers are also called shaft clamp spring pliers and are used for disassembling and assembling the shaft external clamp springs, and the inner clamp spring pliers are also called hole clamp spring pliers and are used for disassembling and assembling the hole clamp springs. At present, the clamp spring pincers on the market often have single functions, and most clamp spring pincers only support single inner clamp or outer clamp functions and cannot be rapidly switched according to actual requirements, so that the application range of the clamp spring pincers is limited. Therefore, it is important to develop a snap spring clamp with quick switching of the functions of the inner clamp and the outer clamp. Disclosure of Invention Aiming at the existing defects, the utility model provides the clamp spring pliers with the function of quick gear shifting of the inner clamp and the outer clamp, the clamp spring pliers are convenient to operate, various in functions, suitable for clamp spring installation and disassembly work under various operation environments, stability and multifunctionality in the operation process are realized through the innovative structural design, and the working efficiency and the user experience are greatly improved. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The clamp spring pliers with the inner and outer clamping rapid gear shifting function comprise a fixed body and a movable body, wherein a circular positioning hole is formed in the position, close to the upper end, of the fixed body, a gear shifting pin matched with the positioning hole is arranged in the positioning hole, and a gear boss of an integrated structure is arranged at the rear end of the gear shifting pin; The movable body is close to the gear shifting adjustment groove of upper end department equipped with gear shifting pin looks adaptation, and one side of fixed body is provided with shift button, shift button internal fixation has the spring, the one end of spring and the side fixed connection of fixed body, and the one end of gear shifting pin passes the locating hole in proper order, shifts adjustment groove and spring, and is connected with shift button. Further, the gear shifting adjusting groove of the movable body is v-shaped, and an outer clamping gear concave table and an inner clamping gear concave table are arranged on the movable body and positioned at two ends of the adjusting groove.
