Description
Technical field
The utility model relates to a kind of spanner, particularly a kind of ratchet spanner.
Background technology
Ratchet wrench is the hand tools that cooperatively interacts and use with sleeve, is used for tightening and unscrews screw or nut.The patent No. is that the Chinese patent " ratchet spanner " of CN91226650 discloses a kind of ratchet spanner, and feature is: the ratchet spanner commutation adopts driving lever commutation, sleeve exchanging to finish for the button mode, and this ratchet spanner is mainly by the handle sleeve, stop collar, driving lever, ratchet, parts such as ratchet side's tenon axle are formed.The turning handle sleeve drives stop collar and driving lever gently, and driving lever rotates the sour jujube bar, the same ratchet engaged of ratchet, and commutation is finished.The replacing of sleeve is pressed by button, in the steel ball side of the being retracted into tenon axial trough, changes the relieving button that finishes.Its weak point is, this spanner has only a working head, the environment of complicated station in the time of can not adapting to operation screw or nut, and turning screw or nut moment is less, and in the time of need being screwed into fast or back-outing, still to operate long handle, influenced operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of novel ratchet spanner is provided, and it has a plurality of working heads, the environment of various complicated stations in the time of well adapting to operation screw or nut, high efficiency.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of multiheaded ratchet wrench, comprise handle, spheric seat, the extension of described spheric seat is connected in an end of described handle by pin, it is characterized in that: the ratchet tool bar is arranged in described spheric seat, described ratchet tool bar is fixed in the spheric seat by interstage sleeve, there is working head at the two ends of described ratchet tool bar, also have ratchet pawl to be connected on the spheric seat in the described spheric seat by ratchet wheel pawl pin, ratchet engaged on described ratchet pawl and the described ratchet tool bar, on the described spheric seat opening is arranged, the operating side of ratchet pawl is exposed the spheric seat surface at busy hour fixed by described opening, in one end of the extension of described handle connection spheric seat spring and steel ball are arranged, the triangle end engagement of described steel ball and ratchet pawl, the other end of described handle has working head, constitutes T type work structuring with the working head at described ratchet tool bar two ends.
For optimizing technique scheme, the measure that the utility model is taked also comprises:
Described working head is a changeable type ring wrench seat.
Described working head is the hexagonal spanner.
Described working head is the fixed muffle spanner, and described ratchet tool bar has hollow-core construction.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, a plurality of working heads that have T type structure, the environment of various complicated stations in the time of well adapting to operation screw or nut, high efficiency;
2, the instrument use can both be done in three ends of T type, and can join the instrument of difformity different size;
3, T type ratchet spanner can be fixedly specification and two kinds of forms of combined type.When T type ratchet spanner was the fixed muffle specification, the ratchet tool bar was a hollow-core construction, can avoid the extension elongation of screw rod during to the long bolt operation, reached the convenient working function.When T type ratchet spanner was combined type, three kinds of different size tool heads can be joined in three ends, and three kinds of different size screws are carried out operation, reached the convenient function of using.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Embodiment 1:
With reference to Fig. 1~Fig. 4, the utility model comprises handle 8, spheric seat 1, and the extension 11 of described spheric seat 1 is connected in an end 10 of handle 8 by pin 9.1 li ratchet tool bar 2 is arranged at spheric seat, described ratchet tool bar 2 is fixed on 1 li of spheric seat by interstage sleeve 15.There is ring wrench seat 14 at the two ends of ratchet tool bar 2, constitute T shape with handle 8, and steel ball on the ring wrench seat 14 and spring structure can fixedly the instrument of different size be pullover easily.Spheric seat also has ratchet pawl 3 for 1 li, and ratchet pawl 3 is connected on the spheric seat 1 by ratchet wheel pawl pin 4, and ratchet pawl 3 can rotate around ratchet wheel pawl pin 4.Be connected with ratchet 19 on the ratchet tool bar 2, ratchet 19 engagements on cat's paw on the ratchet pawl 3 and the ratchet tool bar 2 make ratchet 19 can only make folk prescription to rotation.Opening 13 is arranged on the spheric seat 1, and the operating side 12 of ratchet pawl 3 is exposed spheric seat surface 16 at busy hour fixed by described opening 13, is convenient to switch operation.In one end 10 of the extension 11 of handle 8 connection spheric seats 1 spring 7 and steel ball 6 are arranged, described steel ball 6 meshes with the triangle end 5 of ratchet pawl 3, and under the effect of spring 7 and steel ball 6, ratchet pawl 3 is positioned at working position, makes ratchet 19 can only make folk prescription to rotation.Press the operating side 12 of ratchet pawl 3, ratchet pawl 3 rotates around ratchet wheel pawl pin 4, ratchet pawl 3 can be positioned at another working position, thereby changes ratchet 19 rotating directions.The other end 18 of handle 8 also is provided with ring wrench seat 14, constitutes T type work structuring with the working head 14 at described ratchet tool bar 2 two ends.
