Abstract
The utility model discloses a gear ring positioning device of a ratchet wrench, which comprises a wrench body, a gear ring and a clamp spring, wherein a mounting hole is arranged at the front end of the wrench body, the gear ring is arranged in the mounting hole, and a cavity used for placing a stop dog meshed with the gear ring is arranged on the wrench body. The gear ring positioning device is characterized in that a protective cover covers the cavity, a first clamping groove is arranged in the gear ring , a second clamping groove corresponding to the first clamping groove in position is arranged on the inner side of the mounting hole, the clamp spring is clamped in both the first clamping groove and the second clamping groove, and two end parts of the clamp spring are pressed on the protective cover; and the gear ring positioning device has the following advantages: the clamp spring is directly clamped between the gear ring and the wrench body to position the gear ring, so that the traditional seal cover is omitted, and processing is simple; and in addition, poking holes are arranged at two end parts of the clamp spring, so that mounting and dismounting of the clamp spring are facilitated.
Description
Technical field
The utility model relates to a kind of ratchet spanner, relates in particular to a kind of gear ring positioner of ratchet spanner.
Background technology
At present, the gear ring of a lot of ratchet spanneres, be to fix gear ring by capping and a jump ring that is enclosed within on gear ring on the market.But this fixed form is higher to the concentricity requirement between capping endoporus and outer ring, has caused the difficulty of processing of spanner to increase.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of gear ring positioner of processing simple ratchet spanner.
the utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of gear ring positioner of ratchet spanner, comprise and pull body, gear ring and jump ring, the described front end of pulling body is provided with installing hole, described gear ring is arranged in described installing hole, the described inner chamber that is provided with on body for placing the block that is meshed with described gear ring of pulling, be coated with over cap on described inner chamber, be provided with the first draw-in groove on described gear ring, the inboard of described installing hole is provided with position second draw-in groove corresponding with described the first draw-in groove, described jump ring is connected in described the first draw-in groove and described the second draw-in groove simultaneously, the both ends of described jump ring are pressed on described over cap.
The both ends of described jump ring are provided with respectively pulling hole.
Compared with prior art, the utility model has the advantages that owing to jump ring directly being stuck in gear ring and pulling the location of carrying out gear ring between body, saved traditional capping, make its processing simple; And the both ends of jump ring are provided with respectively pulling hole, facilitate the dismounting of jump ring.
