Description

12 jiaos of coupling box spanners

Technical field

The utility model relates to the spanner technical field, specifically is a kind of 12 jiaos of coupling box spanners.

Background technology

One comprises 12 jiaos of coupling box spanners wrench body and pulls mouth, and the said mouth of pulling is located at the wrench body end, and the said endoporus of pulling mouth is to be used for the rectangular opening that matches with 12 jiaos of plum blossom bolt heads.There is following shortcoming in 12 jiaos of coupling box spanners of above prior art: at some special occasions; Box spanner is not when having enough spatial rotational; Can only box spanner be changed angle again from the bolt head taking-up is inserted in; More likely can't be inserted in and can not use, this has brought inconvenience for normal the use.

The utility model content

The technical problem that the utility model will solve is to provide a kind of at the also employable 12 jiaos of coupling box spanners of the special occasions that does not have enough rotation spaces.

The technical scheme of the utility model is, a kind of 12 jiaos of coupling box spanners with following structure are provided, and comprises wrench body and plays the part of mouth; It also comprises sour jujube seat, very heavy spring, very heavy; The center of said sour jujube seat is provided with interior 12 jiaos of plum blossom holes, said sour jujube seat axial limiting in playing the part of the hole of mouth, and with play the part of mouth and be rotatably connected; A said very heavy end is rotatably connected in playing the part of the groove of mouth, and its other end offsets with the periphery of sour jujube seat through very heavy spring all the time.

A said very heavy end is rotatably connected and in playing the part of the groove of mouth, is meant, said very heavy being installed in through rotating shaft in the groove of playing the part of mouth, said very heavy spring is socketed in the rotating shaft, said very heavy spring one end is fixed on plays the part of on the mouth, the other end be against mutually very heavy on.

Said sour jujube seat axial limiting is meant in playing the part of the hole of mouth; The middle part of said sour jujube seat is provided with radial ringed convexity; Said sour jujube seat is embedded in the stepped hole of playing the part of mouth, and the opening part of said stepped hole of playing the part of mouth is also removable to be connected with capping, and the outer face of the radial protrusion of said capping and sour jujube seat offsets.

The end of said wrench body also is socketed with sheath.

After adopting said structure, the utility model compared with prior art has the following advantages: through the effect of very heavy and very heavy spring; Make sour jujube seat ability one-directional rotation; And oppositely skid, such 12 jiaos of coupling box spanners also can use at the special occasions that does not have enough rotation spaces, need not to make sleeve to extract and change angle again from bolt head and are inserted in; Guarantee normally easy to usely, scope is wide.

As improvement, a said very heavy end is rotatably connected and in playing the part of the groove of mouth, is meant, saidly very heavyly is installed in the groove of playing the part of mouth through rotating shaft; Said very heavy spring is socketed in the rotating shaft, and said very heavy spring one end is fixed on plays the part of on the mouth, the other end be against mutually very heavy on; Simple in structure, compactness.

As improvement; Said sour jujube seat axial limiting is meant that in playing the part of the hole of mouth the middle part of said sour jujube seat is provided with radial ringed convexity, and said sour jujube seat is embedded in the stepped hole of playing the part of mouth; The opening part of said stepped hole of playing the part of mouth is also removable to be connected with capping; The outer face of the radial protrusion of said capping and sour jujube seat offsets, easy accessibility, good stability.

As improvement, the end of said wrench body also is socketed with sheath, increases the sense that grips of receiving.

Accompanying drawing 1 is the generalized section of 12 jiaos of coupling box spanners of the utility model.

Accompanying drawing 2 is schematic top plan view of 12 jiaos of coupling box spanners of the utility model.

As shown in the figure: 1, wrench body, 2, play the part of mouth, 3, the sour jujube seat, 4, capping, 5, very heavy spring, 6, very heavy, 7, sheath.

The specific embodiment

Be described further below in conjunction with 12 jiaos of coupling box spanners of accompanying drawing the utility model.

Like Fig. 1, shown in Figure 2,12 jiaos of coupling box spanners of the utility model comprise wrench body 1 and play the part of mouth 2; It also comprises sour jujube seat 3, very heavy spring 5, very heavy 6, and the center of said sour jujube seat 3 is provided with interior 12 jiaos of plum blossom holes, and said sour jujube seat 3 axial limitings are in the hole of playing the part of mouth 2; And with play the part of mouth 2 and be rotatably connected; An end of said very heavy 6 is rotatably connected in the groove of playing the part of mouth 2, and its other end end offsets with the periphery of sour jujube seat 3 through very heavy spring 5 all the time, and sour jujube seat 3 is under very heavy 6 effect like this; The ability one-directional rotation, and oppositely skid.

An end of said very heavy 6 is rotatably connected and in the groove of playing the part of mouth 2, is meant, said very heavy 6 are installed in the groove of playing the part of mouth 2 through rotating shaft, and said very heavy spring 5 is socketed in the rotating shaft, and said very heavy spring 5 one ends are fixed on plays the part of on the mouth 2, and the other end is against on very heavy 6 mutually.

Said sour jujube seat 3 axial limitings are meant in the hole of playing the part of mouth 2; The middle part of said sour jujube seat 3 is provided with radial ringed convexity; Said sour jujube seat 3 is embedded in the stepped hole of playing the part of mouth 2; The opening part of said stepped hole of playing the part of mouth 2 is also removable to be connected with capping 4, and said capping 4 offsets with the outer face of the radial protrusion of sour jujube seat 3.

The end of said wrench body 1 also is socketed with sheath 7.
