Description
Technical field
The utility model belongs to a kind of tool, specifically, more particularly to a kind of hole ratchet spanner living.
Background technology
Spanner is common tool in production activity.But in the occasion of some narrow spaces, sometimes using common wrench
It is inconvenienced, because tightening a bolt or many circles of nut needs rotation, and common spanner cannot rotate 360 degree, need
Spanner is removed from bolt or nut, then the suitable angle repetitive operation of reselection, such to pull not only process
Complexity, inefficiency, and the revolution of bolt either nut may be caused to keep elasticity bolt or nut very inconvenient.Cause
There are some ratchet spanneres in the prior art in this, can control spanner and only make unidirectional movement without causing to turn round.It is existing
It is singly reversely rotated by ratchet structure realization inside ratchet spanner on the market, but it twists the nut of different model
It must be by the sleeve of different model.Therefore the shortcomings that current ratchet spanner：(1) dependence is big, and the nut for twisting different model must
It must be by corresponding sleeve, if will be helpless without corresponding sleeve；(2) existing ratchet spanner internal structure is complicated, adds
Work process is complicated, higher to required precision, also just improves the requirement to processing machine and staff；(3) spine with sleeve
Wheel spanner is not suitable for due to increasing sleeve in narrow Space-Work.
Utility model content
The utility model aim is to provide a kind of work hole ratchet spanner that can arbitrarily adjust clamping range size, to overcome
Drawbacks described above existing for ratchet spanner with sleeve in the prior art.
The utility model is realized using following technical scheme：
The work hole ratchet spanner, including handle and wrench body, the wrench body include shell, the shell is
Bottom opening structure, the enclosure interior are equipped with ratchet and chuck assembly, and the ratchet is connect with click-fit realizes ratchet list
To rotation, the chuck assembly includes more than two claws, jaw adjustment disk and claw positioning disk, before the jaw adjustment disk
Face is equipped with rotation regulating part, and the back side is equipped with screw thread A, and the claw positioning disk is equipped with the guiding slot port of installation claw, the card
Pawl is equipped with the screw thread B being connected with the screw thread A of jaw adjustment disk, and the claw positioning disk is fixedly connected with ratchet.
The handle inner is hollow structure, and pawl and spring is arranged in the handle.
The utility model further includes adjusting tool, and the adjusting tool includes that adjusting rod and fixation are located at adjusting rod one end
Bevel pinion.
The rotation regulating part is bevel gear wheel, and bevel gear wheel is for engaging connection with bevel pinion.
The upper part of the housing is equipped with adjustment hole, and adjustment hole is used to pass through adjusting tool.
The upper part of the housing is equipped with peep hole, and claw and nut cooperation are observed by observation panel when peep hole is used for work
Situation.
Compared with prior art, the utility model has the beneficial effects that：
(1) the utility model can change size due to the structure contacted with nut, so need not can by sleeve
To twist the nut of different model, this also just solves the disadvantage that the existing ratchet spanner with sleeve cannot work in narrow space；
(2) the utility model internal structure is simple, so manufacturing simple, reliability height.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, hole ratchet spanner living described in the utility model, including handle 1 and wrench body 2, spanner
Ontology 2 includes shell 3, and shell 3 is bottom opening structure, and shell 3 is internally provided with ratchet 6 and chuck assembly, ratchet 6 and pawl 10
It is connected and realizes limitation 6 single direction rotation of ratchet, chuck assembly includes more than two claws 11, jaw adjustment disk 7 and claw
Positioning disk 8,7 front of jaw adjustment disk are equipped with rotation regulating part, and the back side is equipped with screw thread A13, and claw positioning disk 8 is equipped with installation card
The guiding slot port of pawl 11, claw 11 are equipped with the screw thread B14 being connected with the screw thread A13 of jaw adjustment disk 7, claw positioning disk
8 are fixedly connected with ratchet 6.
1 inside of handle is hollow structure, pawl 10 and spring 9 is arranged in handle 1, pawl 10 is under the effect of 9 elastic force of spring
It is contacted with ratchet 6 so that ratchet 6 can only be along the counter-rotating in screw tightening direction.
3 top of shell is equipped with peep hole 4, can observe the case where claw 11 coordinates with nut by peep hole 4 when work,
The person of being conveniently operated according to circumstances adjusts the size of 11 survivor of a murder attempt of claw.
