Description

The multiplex switching sleeve of electric wrench
Technical field
The utility model relates to the hardware & tools field, has related in particular to the multiplex switching sleeve of a kind of electric wrench.
Background technology
Electric wrench is to realize bolt, screw nut mounting machine tool efficient tool, but on the electric wrench function, exist can not dual-purpose to having cross and a word screw, tapping screw to tighten, the defect of unscrewing.Therefore, be necessary existing electric wrench structure is optimized.
Summary of the invention
The utility model, for the defect existed in prior art, provides a kind of simple in structure, and modern design is simple in structure, easily manufactured, has increased the multiplex switching sleeve of the use function of electric wrench.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The multiplex switching sleeve of electric wrench, comprise sleeve body and spring clip headgear, sleeve body comprises the first cylindrical shell and the second cylindrical shell, the first cylindrical shell and the second cylindrical shell are connected as a single entity, described the second cylindrical shell stretches in the spring clip headgear, described the second drum surface is provided with steel bead groove, places steel ball in steel bead groove, and the second cylindrical shell end is arranged with Compress Spring, pad, jump ring.
As preferably, described pad is set in the end face of Compress Spring.
As preferably, described the second barrel front end is provided with jump-ring slot, and described jump ring snaps in jump-ring slot.
As preferably, be provided with inwardly protruded fixture block in described spring clip headgear, the fixture block end contacts with the second drum surface; One side of described fixture block is inclined-plane, and described fixture block presses steel ball by its inclined-plane.
The utility model, owing to having adopted above technical scheme, has significant technique effect:
The utility model is simple in structure, easy to assembly, increased the use function of electric wrench, this installs an end is the square endoporus coordinates other end self-locking spring chuck with electric wrench, is that hexagonal internal bore is criticized handle with the standard bottle opener and coordinated, can be to cross, one word screw, tapping screw, handling, can also install hexagonal-handle twist drill and advance holing on various materials.Increase the multi-purpose function of electric wrench by multiplex switching sleeve, can realize a tractor serves several purposes.This device manufacturing process is simple, has very high practicality.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1 and specific embodiment, the utility model is described in further detail:
embodiment 1
The multiplex switching sleeve of electric wrench, as shown in Figure 1, comprise sleeve body 6 and spring clip headgear 1, sleeve body 6 comprises the first cylindrical shell 61 and the second cylindrical shell 62, the first cylindrical shell 61 and the second cylindrical shell 62 are connected as a single entity, and described the second cylindrical shell 62 stretches in spring clip headgear 1, and described the second cylindrical shell 62 surfaces are provided with steel bead groove 2, the interior placement steel ball of steel bead groove 23, the second cylindrical shell 62 ends are arranged with Compress Spring 4, pad 5, jump ring 7; Described pad 5 is set in the end face of Compress Spring 4.The second cylindrical shell 62 front ends are provided with jump-ring slot 71, and described jump ring 7 snaps in jump-ring slot 71.Be provided with inwardly protruded fixture block 11 in spring clip headgear 1, fixture block 11 ends contact with the second cylindrical shell 62 surfaces; One side of described fixture block 11 is inclined-plane, and described fixture block 11 presses steel ball 3 by its inclined-plane.
The assembly technology of the multiplex switching sleeve of described electric wrench is as follows:
A. 3 two upper some lubricating grease of steel ball, in the steel bead groove 2 on second cylindrical shell 62 of packing into;
B. spring clip headgear 1 chamfered end is inserted in to the second cylindrical shell 62, and pushes away forward until steel ball blocks;
C. Compress Spring 4 is inserted in to sleeve body 6 and the middle end of shifting onto, the space of spring clip headgear 1;
D. pad 5 is enclosed within to the end face of Compress Spring 4;
E. jump ring 7 is snapped in the jump-ring slot 71 of the second cylindrical shell 62.
Zhuan Luo Silk bottle opener is criticized and the hexagonal-handle twist drill operation principle
1. bottle opener is criticized in handle or the multiplex reducing sleeve front end of hexagonal-handle twist drill insertion electric wrench inner hexagonal hole and firmly advanced, because the stressed upward sliding of steel ball in hexagon ring moves forward collet, like this bottle opener is criticized to handle or hexagonal fried dough twist drillstock is inserted into the end, at this moment steel ball fall to just in time being stuck in that bottle opener is criticized or the draw-in groove of hexagonal fried dough twist drillstock in, bottle opener is criticized and hexagonal-handle twist drill can not come off like this.
2. when end-of-job will take out, the spring clip headgear is outwards pushed away, at this moment steel ball upwards has space.Bottle opener is criticized or the hexagonal fluted drill just can be pulled out.
3. electric wrench output shaft square toes are plugged multiplex switching sleeve, and other end loads onto hexagonal-handle twist drill as required or bottle opener is criticized.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
