Abstract
The utility model discloses a ratchet spanner, comprising a spanner body (1) and a ratchet device. The ratchet device is arranged at one end of the ratchet body (1); a through hole (9) is arranged on the ratchet device, and the ratchet device is detachable. The ratchet spanner has low use cost due to the detachable characteristic.
Description
Technical field
The utility model relates to a kind of hand-operated tools, specifically is a kind of ratchet spanner.
Background technology
The ratchet device that the ratchet spanner of prior art comprises wrench body and is located at Wrench head, whole ratchet device are arranged in the cavity, and promptly ratchet device is on-dismountable.Because this ratchet device is for fixing, non-removable, if therefore in use the parts of ratchet device break down, then can only abandon and buy new spanner, thereby cause the use cost of prior art ratchet spanner higher.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides a kind of use cost low ratchet spanner.
The technical scheme of the utility model is, a kind of ratchet spanner is provided, and comprises wrench body and ratchet device, and described ratchet device is located at an end of wrench body, and said ratchet device is provided with through hole, and described ratchet device is removable ratchet device.
Described removable ratchet device comprises housing, the ratchet that is rotatably assorted with housing, the jump ring that is used to limit the ratchet axial location, with offset very heavy of ratchet and the torsion spring that is used to limit very heavy rotation; One end and the housing of said ratchet offset, and the other end of said ratchet is in jump ring is limited to housing; Described very heavy and torsion spring are hinged on the inner walls; One resistance arm of said torsion spring and very heavy offseting, another resistance arm and the inner walls of said torsion spring offset; Also be provided with the opening that exposes jump ring two bayonet sockets on the described ratchet.
Described very heavy and torsion spring are hinged on the inner walls through alignment pin, and described alignment pin is threaded on the housing.
The cross section of described through hole is positive pentagon.
After adopting above structure, the utility model compared with prior art has the following advantages:
When the utility model ratchet spanner need be changed parts, through clamp being stretched into two bayonet sockets to take out jump ring and ratchet, promptly replaceable ratchet spun off alignment pin and can take out very heavy and torsion spring afterwards, and it is convenient in the extreme to use.Therefore if in use the parts of ratchet device break down or when needing to change ratchet, as long as change parts or the ratchet that breaks down, thereby make that the use cost of the utility model ratchet spanner is very low.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; A kind of ratchet spanner of the utility model comprises wrench body 1 and ratchet device, and described ratchet device is located at an end of wrench body 1; Said ratchet device is provided with through hole 9, and described ratchet device is removable ratchet device.
Described removable ratchet device comprises housing 2, the ratchet 3 that is rotatably assorted with housing 2, the jump ring 4 that is used to limit ratchet 3 axial locations, with ratchet 3 offset very heavy 5 and be used to limit very heavy 5 torsion springs 6 that rotate; One end and the housing 2 of said ratchet 3 offset; The other end of said ratchet 3 is in jump ring 4 is limited to housing 2; Be that annular edge in the housing 2 prop up ratchet 3 guaranteeing its position, described ratchet 3 other ends and housing 2 be equipped with the groove that supplies jump ring 4 placements with respect to the position; Described very heavy 5 are hinged on housing 2 inwalls with torsion spring 6; One resistance arm of said torsion spring 6 and very heavy 5 offsets, and another resistance arm of said torsion spring 6 and housing 2 inwalls offset, in order to limit very heavy 5 rotations and to reset very heavy 5; Also be provided with the opening 7 that exposes 4 liang of bayonet sockets of jump ring on the described ratchet 3, in order to put in clamp.
Described very heavy 5 are hinged on housing 2 inwalls through alignment pin 8 with torsion spring 6, and described alignment pin 8 is threaded on the housing 2, is threaded to be convenient to very much dismounting.
The cross section of described through hole 9 is positive pentagon, and this through hole 9 supplies bolt head to insert.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
