Embodiment Construction

[0010] Attached below figure 1 The present invention will be further described.

[0011] The box wrench includes a casing 4, a shaft II 3 rotatably installed in the casing 4, and a worm wheel 5 rotatably installed in the casing 4. The bottom of the shaft II 3 is provided with a worm 7, and the worm 7 and the worm wheel 5 Mesh with each other, the sleeve 6 passes through the shell 4 and is fixed on the worm wheel 5, and the axis of the sleeve 6 coincides with the axis of the worm wheel 5. When in use, clamp the chuck of the pistol drill to the head end of the shaft II 3, then place the sleeve 6 on the nut or bolt head in the axial direction, and then press the switch of the pistol drill to make the drive shaft II 3 rotate , the shaft II 3 rotates to drive the worm wheel 5 to rotate by means of the worm 7, so that the sleeve 6 rotates to disassemble or install and tighten the nut or bolt head. Due to the engagement of the worm wheel 5 and the worm screw 7, the axis of the shaf...

Abstract

The invention relates to a socket spanner comprising a shell, a shaft II and a worm gear. The shaft II and the worm gear are rotatably disposed in the shell. A worm is arranged at the bottom of the shaft II, and is mutually meshed with the worm gear. A socket penetrates the shell to be fixed on the worm gear, and the axis of the socket mutually coincides with that of the worm gear. During use, the head end of the shaft II is clamped by a chuck of a piston drill, the socket is axially sleeved on a nut or a bolt head, a switch of the piston drill is pressed to drive the shaft II to rotate, the worm gear is driven to rotate by the worm, and the socket is driven to rotate to have the nut or the bolt head removed or screwed tightly. Due to the fact that the worm gear is meshed with the worm and the axis of the shaft II is mutually vertical to that of the socket, operation comfortableness and work efficiency are improved, and the problems that an open spanner is easy to slip and causes damage to the nut are solved.

Description

technical field [0001] The invention relates to a hardware tool, in particular to a socket wrench. Background technique [0002] Among the currently used socket tools, the axial socket wrench is commonly used. There is no socket wrench that changes from the axial direction to the vertical direction. question. Because the automobile manufacturing process is to lift the complete engine into the engine cabin to install and fix it after the complete engine is assembled, but it is a car-like repair during maintenance, and the engine cannot be lifted out of the engine room for maintenance, unless the engine can be lifted out of the engine room for overhaul. Nowadays, the engine compartment parts of the middle and high-end automobiles are very compact and narrow, and the space is limited, so it is very difficult to disassemble the bolts. At present, car maintenance basically uses handle sleeves, open-end wrench and ring wrench tools for disassembly and assembly. During the disass...
