Description
Technical field
The present invention relates to a kind of ratchet spanner.
Background technology
Please refer to " Reversible Ratchet Wrench " patent case of No. the 7278339th, U.S. Patent number, it is a kind of reversing ratchet wrench.This ratchet spanner utilizes a ring (ring) to drive the change in location that a conversion assembly (switching member) produces both direction, and the conversion assembly front end is provided with and compresses assembly (pressing member) and elastic parts (elastic element) and come flexible promotion pawl (pawl), described pawl can be controlled between two positions move, and be engaged on the runner assembly (drivemember).
Described existing structure still has the many places shortcoming in practicality, because the ring of this ratchet spanner is hubbed on the runner assembly, so the pivot of this ring is and the same axle center of described runner assembly, but conversion assembly is hubbed in a containing hole of ring, so the pivot of the pivot of conversion assembly and ring is not or not same axle center.That is to say that ring becomes complicated with conversion assembly commutation action between the two in control, and the untrue problem of start takes place easily.
The pivot of the pivot of described conversion assembly and ring is not or not same axle center again, under the project organization of present twocouese operating position, when utilizing this conversion assembly to produce extra operating position, the space of ratchet spanner has been subjected to very big restriction, be not only that a containing hole just can address this problem, therefore caused the ratchet spanner head to become big problem and taken place.
Moreover, described pawl is that the control that is subjected to conversion assembly can produce change in location, and conversion assembly to drive the formed camber line of motion track compress assembly be opposite track with the formed camber line of the motion track of pawl, therefore the described assembly that compresses must be made and can stretch in conversion assembly, can drive pawl moves, but utilize opposite arc trajectory to drive the design of pawl like this, also cause the problem that has some setbacks of process of commutation start, and cause the too much shortcoming of spare part.
