Embodiment Construction

[0013] see figure 1 , with reference to figure 2 , image 3 , Figure 4 , the built-in rail quick clip wrench of the present invention includes a handle 1, a fixed pliers body 2, a movable pliers body 3 and a push button 4. The handle 1 and the fixed pliers body 2 are integrated. The fixed pliers body 2 is provided with a step-shaped slide hole 21 for the movable pliers body 3 to slide, and the periphery of the slide hole forms a built-in guide rail 22 of the movable pliers body, and a chute connecting the slide hole 21 is provided on one side of the fixed pliers body twenty three. The movable pliers body 3 is embedded in the stepped sliding hole 21 of the fixed pliers body and can slide along the built-in guide rail 22 . The handle 1 is embedded with a strip-shaped tooth plate 5 at its connection end with the fixed pliers body 2, and the tooth plate forms the bottom plate of the stepped sliding hole 21, and the end surface of the movable pliers body 3 that contacts the ...

Abstract

The invention relates to a guide rail built-in fast-clamping spanner, which comprises a handle, a fixed clamp body, a movable clamp body and a pushing button used for pushing the movable clamp body to move, which are connected into a whole. The fixed clamp body is provided with a step-shaped sliding hole through which the movable clamp body can slide, a built-in guide rail of the movable clamp body is formed on the periphery of the sliding hole, and the movable clamp body is embedded in the step-shaped sliding hole of the fixed clamp body and can slide along the built-in guide rail; and a piece of rectangular tooth board is embedded at the connecting end of the handle and the fixed clamp body, and the tooth board forms a bottom board of the step-shaped sliding hole. A contacting end face of the movable clamp body and the bottom board can be divided into three sections in the movable clamp body moving direction: the inner section is a flat-board section, the middle section is a groove section, and the outer section is a rack section. The guide rail built-in fast-clamping spanner has the advantages of simple structure, high adjusting speed and single hand operation, and the movable clamp body can form a locking state when clamping workpieces, without looseness.

Description

technical field [0001] The invention relates to a hand tool used for tightening nuts and other parts, in particular to a quick clip wrench with a built-in guide rail. Background technique [0002] The adjusting wrench of the prior art generally includes a handle and a fixed pliers body connected to the front end of the handle, a movable pliers body and a worm and gear mechanism. The worm and gear mechanism is used to control the movement of the movable pliers body to achieve different openings. Time to rotate the worm gear; or to make the jaws closer, use a motorized adjustable wrench, which uses a battery-driven motor to speed up the movement of the jaws to adjust the opening and closing of the jaws, saving the need to adjust the jaws time. Both of the above tools require some mechanical drive or transmission for the adjustment function. Either the structure is complex, or the adjustment speed is slow. The requirements of simple structure and fast adjustment speed cannot...
