Description
Technical field
The utility model relates to a kind of adjustable ratchet wheel spanner, belongs to wrench, spanner technical field.
Background technology
Certain moment of rotation is all needed during the use of prior art monkey wrench, if narrow space, use just extremely inconvenient, need first by the buckle of spanner and hex(agonal)screw or nut phase fit, then positively this monkey wrench of switching to certain angle, to rotate this hex(agonal)screw or nut, now, can not this traditional type monkey wrench of reverse switching, otherwise this hex(agonal)screw or nut and then will go back to original position.Therefore, the opening of this monkey wrench operationally just must be made first to depart from this hex(agonal)screw or nut, then fit and switching again, so repeatedly operate for several times, just can reach the object that this hex(agonal)screw or nut are screwed or unscrewed, this is rather inconvenience operationally.
Existing ratchet spanner comprise have extend handle wrench body and rotated the wrench be assemblied in wrench body head by ratchet and pawl arrangement, the center of wrench be provided with the through hole of nut form fit or be provided with the lateral open channel extending to inner peripheral surface from outer peripheral face at the head of the wrench body of ratchet spanner, wrench be provided with from outer peripheral face extend in it in hexagon through hole, corresponding with lateral open channel in side direction open channel.
Although ratchet spanner solves prior art split shed spanner need larger rotation space, the astomous problem of ratchet spanner, the size of spanner bayonet socket can not be regulated, make the spanner of a specification be only applicable to the nut of fixing model.
The wrench of existing adjustable ratchet wheel spanner and ratchet are made as one, the bayonet socket of wrench is arranged in ratchet, Wrench head volume is comparatively large, although solve the problem of the nut adapting to different size model, is not easy to extend in comparatively narrow and small groove or other positions and goes.
Utility model content
The technical problems to be solved in the utility model is, not enough for prior art, proposes one adjustable ratchet wheel spanner more easily.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of adjustable ratchet wheel spanner, comprise wrench body and Wrench head, described Wrench head comprises head shell, ratchet and pawl arrangement and wrench, described wrench comprises fixed jaw, described fixed jaw and described ratchet and pawl arrangement affixed, and described head shell is located between described fixed jaw and described ratchet and pawl arrangement; Described ratchet and pawl arrangement comprises pawl seat, the ratchet be fixedly arranged on described pawl seat, the first ratchet and the second ratchet, described first ratchet and described second ratchet interval be embedded in described Wrench head, described ratchet and pawl arrangement is provided with opening, and the spacing of described opening is less than the spacing of the first ratchet and the second ratchet; Described wrench is provided with boss, and described boss inserts in described ratchet.
The improvement of technique scheme is: described ratchet and pawl arrangement is provided with the some projections to described ratchet and pawl arrangement central elevation, and the side of described boss is provided with the groove with described male cooperation.
The improvement of technique scheme is: on the equally spaced madial wall being distributed in described ratchet and pawl arrangement of described projection.
The improvement of technique scheme is: described wrench also comprises lead screw transmission mechanism, described lead screw transmission mechanism is embedded in described wrench, described lead screw transmission mechanism comprises roller, movable jaw and is fixed in the interlock screw mandrel of movable jaw, described roller and described interlock screw mandrel are threaded connection, be provided with in described fixed jaw and allow the reciprocating through hole of described interlock screw mandrel, the fixed axis of described roller is fixedly arranged in described wrench.
The improvement of technique scheme is: described fixed jaw and described movable jaw are equipped with the inclined-plane that an inclination angle is 30 °.
The beneficial effect of the utility model employing technique scheme is: between the utility model first ratchet and the second ratchet, interval is greater than the open space of ratchet and pawl arrangement, and this makes the ratchet of opening can not depart from ratchet.
Of the present utility model by fixed jaw and described ratchet and pawl arrangement affixed make described wrench and described ratchet and pawl arrangement affixed, and the described head shell of sandwiched between, form a three-decker, this makes adjustable ratchet wheel spanner of the present utility model can be applied to more narrow occasion, groove as narrower in width.
Fixed jaw of the present utility model and movable jaw are equipped with the inclined-plane that an inclination angle is 30 °, with middle force easy to use.
