Abstract

A kind of ratchet spanner, it includes spanner handle, ratchet and end cap;There is ring-shaped groove on the rounded nose surface of the spanner handle, and is hollow structure, and its internal fixation is evenly equipped with ratchet and spring, and spring press against ratchet all the time;The ratchet center of circle is hexagon through hole, and gear teeth tooth form is right-angled trapezium;The end cap can be stuck in the ring-shaped groove of spanner handle, and ratchet is clamping in centre.This spanner can be realized in limited space, by small angle rotation spanner, repeatedly on set in the case of hex bolts or nut, part can just not tightened, convenient and swift.

Description

A kind of ratchet spanner
Technical field
The utility model is related to a kind of spanner, more particularly to a kind of ratchet spanner, belongs to machining tools art.
Background technology
In daily life, hex bolts and hex nut are fastened and space that spanner can be rotated again very When limited, general spanner needs operator to remove spanner after turning an angle, then put again again bolt or Person's nut is to continue to tighten, with this repeatedly, is inconvenient.
The content of the invention
The purpose of this utility model is to provide a kind of ratchet spanner, can very easily without extract repeatedly bolt and Just it can continuously be tightened in the case of nut, it is convenient and swift.
In order to realize this purpose, the utility model employs following proposal:A kind of ratchet spanner, it is characterised in that:It Including spanner handle, ratchet and end cap, the end cap is identical two, can be stuck in two annulars on spanner handle In groove, it is clipped in the middle so that ratchet is fixed.
The spanner handle is in having ring-shaped groove, inside to be on two identical symmetrical member compositions, its rounded nose Hollow structure, can load ratchet, and fixation is evenly equipped with ratchet and spring, and spring press against the gear teeth that ratchet is attached to ratchet all the time On.
The center of circle of the ratchet is hexagonal through hole, and gear teeth tooth form is right-angled trapezium.
The beneficial effects of the utility model are:When rotation space is by limited time, rotate in an anti-clockwise direction spanner, and bolt or Nut is then remained stationary as, and can just be continued to tighten part clockwise after turning an angle, be put again without removing repeatedly Hex bolts or nut, improve operability, improve efficiency.
Brief description of the drawings
Fig. 1 is outside drawing of the present utility model.
Fig. 2 is A-A directions view in full section.
Fig. 3 is B-B directions view in full section.
Fig. 4 is end cap schematic diagram.
Wherein:1st, spanner handle;2nd, ratchet;3rd, ratchet;4th, spring;5th, hexagon through hole;6th, end cap;7th, ring-shaped groove.
Embodiment
As Figure 1-4, in use, hexagon through hole 5 is enclosed on the hex bolts or nut for needing to tighten, spring 4, which press against ratchet 2, is stuck on the right-angle side of the gear teeth of ratchet 3, when rotating clockwise spanner handle 1 with hand, ratchet 2 and spring 4 with Spanner handle 1 is rotated, and is also rotated clockwise so as to head on ratchet 3;When space is limited, turn to after certain angle, turn counterclockwise Wrench handle 1, and 3 sets of ratchet hex bolts or nut then remain stationary as, ratchet 2 is under the pressure effect of spring 4 with pulling Hypotenuse of the handle 1 along the gear teeth of ratchet 3 is slided counterclockwise, after certain angle is gone to, and ratchet 2 is under the pressure effect of spring 4, again On the right-angle side that the gear teeth of ratchet 3 can be withstood, continue to rotate clockwise spanner handle 1, then ratchet 2, which may proceed to head on ratchet 3, rotates, from And tighten hex bolts or nut.
