In order to solve the problems of the technologies described above, the technical solution of the utility model is: combination wrench is twisted in a kind of two-way automatic control, comprise handle, be arranged on the spanner and the controlling organization that turns to of controlling spanner of handle end, described spanner comprises the outer wheel case that is fixed on handle end, in described outer wheel case, be provided with the wheel disc that portion rotates within it, in the outer peripheral sidewall of described wheel disc, be provided with two-way draw-in groove, the middle part of described wheel disc is provided with the groove that through hole swivel nut is installed, described wheel disc is on end face, to be also hinged with four for blocking the card of through hole swivel nut, describedly turn to controlling organization to comprise to be hinged on the fork on handle, the both sides of described fork hinged place are provided with elastic force snib, described elastic force snib comprises that one end is connected to the spring on fork, the other end of described spring is connected with snib, the other end of described snib is resisted against on the two-way draw-in groove of wheel disc under the effect of spring, the both sides of one end of described fork are provided with the location hook being arranged on handle, on this end, place of described fork, be provided with for hooking the locating hole on location hook.
Further, the through hole of described through hole swivel nut is hexagon or quincunx.
Further, described handle is telescopic telescoping handle.
Compared with prior art, the utlity model has following beneficial effect:
1, the limitation of spatial limitation can be effectively lowered, and the stabilized structure of the solid nut workpiece of cover can be reached;
2, structure is simple and direct, easy to operate, cheap for manufacturing cost;
3, run into the firm nut bolt such as get rusty, can enlarging moment, easily turn on, twist nut bolt easily, can shorten handle, it is handy to use;
4, there is multi-purpose use effect, quite there is industrial utilization.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-telescoping handle, 2-spanner, the outer wheel case of 21-, 22-wheel disc, the two-way draw-in groove of 23-, 24-through hole swivel nut, 25-card, 3-turns to controlling organization, 31-fork, 32-spring, 33-snib, 34-location hook, 35-locating hole.
The specific embodiment
Embodiment mono-: as shown in Figure 1, combination wrench is twisted in a kind of two-way automatic control, comprise telescoping handle 1, what be arranged on the spanner 2 of telescoping handle 1 end and control spanner turns to controlling organization 3, described spanner 2 comprises the outer wheel case 21 that is fixed on telescoping handle 1 end, in described outer wheel case 21, be provided with the wheel disc 22 that portion rotates within it, in the outer peripheral sidewall of described wheel disc 22, be provided with two-way draw-in groove 23, the middle part of described wheel disc 22 is provided with the groove that through hole swivel nut 24 is installed, described wheel disc 22 be on end face, be also hinged with four rotating for blocking the card 25 of through hole swivel nut 24, the described fork 31 that turns to controlling organization 3 to comprise to be hinged on telescoping handle 1, the both sides of described fork 31 hinged places are provided with elastic force snib, described elastic force snib comprises that one end is connected to the spring 32 on fork 31, the other end of described spring 32 is connected with snib 33, the other end of described snib 33 is resisted against on the two-way draw-in groove 23 of wheel disc 22 under the effect of spring 32, the both sides of one end of described fork 31 are provided with the location hook 34 being arranged on telescoping handle 1, on this end, place of described fork 31, be provided with for hooking the locating hole 35 on location hook 34.
In the present embodiment, the through hole of described through hole swivel nut 24 is hexagon.
