Double-snap reversing ratchet wrench

Abstract

The invention relates to a double-snap reversing ratchet wrench to solve the problems of the conventional ratchet wrench that a clutch device is complicated in structure, a plurality of components are arranged to cause low loading torsion, parts are positioned in a single way to cause high processing cost and the service life is short. The double-snap reversing ratchet wrench comprises a handle and a wrench body connected to one end of a stress application rod, and is characterized in that a ratchet perpendicular to the stress application rod is arranged in the wrench body; one end, facing the stress application rod, of the ratchet is provided with a direction switch; the direction switch comprises a direction handle and a steering body which is positioned below one end of the direction handle and is perpendicularly connected with the direction handle; two sides of the steering body are respectively provided with a snap; the bottom end of the steering body is provided with a spring hole seat; the wrench body at one end of the spring hole seat is provided with a cover plate. The double-snap reversing ratchet wrench is provided with a few parts, and is simple in structure and compact in integral structure, the positioning way between the components is flexible, a single component has sufficient strength design space, and the double-snap reversing ratchet wrench transfers large torque and is reliable, wear-resistant, easy to assemble and maintain, and easy and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a double-clip reversing ratchet wrench. Background technique [0002] Because the ratchet wrench is rotatably connected to the end of the operating rod, it can be used to rotate bolts or nuts placed in narrow or inaccessible positions. It is easy to use and widely used. There are many existing ratchet wrench structures, each with its own characteristics. . For example, the patent publication number is CN101618531A, which discloses a ratchet wrench, including a main body, a driving part, a locking part, a reversing device, and a pushing device. The reversing device of this structure includes a control part and a toggle part, and the control part can be The rotating part is set in the shaft hole of the driving part. One end of the control part is provided with a card part, and a push-up device is arranged inside. The push-up device elastically pushes against the positioning...
