Abstract
The utility model discloses a removable telescopic ratchet spanner, including handle and sleeve, the sleeve middle part is provided with the ratchet, the handle front end is provided with the pawl, the pawl passes through bolt fixed connection on the handle, and the pawl is connected with the ratchet meshing in the sleeve, the handle other end seted up the plum blossom flywheel, the ratchet both sides all be provided with protruding structure, with this removable telescopic ratchet spanner, its adopts between pawl and sleeve ratchet the elasticity through the spring that compresses to reach full engagement to the other end card of pawl makes the sleeve can only unidirectional rotating on the handle, when changing the sleeve, as long as take off the bolt, make the pawl withdraw from the cavity, the sleeve can conveniently be changed, all is provided with protruding structure in ratchet both sides, is used for fixing sleeve's position making the sleeve can not take place radial movement, and stable sleeve can let ratchet spanner more laborsaving, easy operation, the practicality is strong, easily uses widely.
Description
Technical field
This utility model relates to ratchet spanner applied technical field, the ratchet spanner of a kind of interchangeable sleeve.
Background technology
Ratchet spanner is a kind of manual screw tightening tool, single head, double end many specifications movable handle double offset ring spanner with ratchet；Be the main plum blossom-like sheath by different specification size and from plum-blossom sleeve by the cloudy key of hinged key and sun key occlusion by the way of connect.Owing to a plum-blossom sleeve has the quincunx through hole of two specifications, make it may be used for the degree of tightness of two kinds of specification screws, thus expand range, save raw material and work time cost.
At present, it is strong that known ratchet spanner has the suitability, the features such as easy to use and cost is low, this ratchet spanner has single head and first two specification double, owing to a sleeve has the through hole of two kinds of specifications, although improve the suitability of spanner by ratchet mechanism, but ratchet spanner is only used for the degree of tightness of two kinds of specification screws, need to prepare the spanner of less model when twisting less kind screw, operation bothers very much.
Utility model content
Prior art is difficult to the needs of people, in order to solve the problem of above-mentioned existence, the utility model proposes the ratchet spanner of a kind of interchangeable sleeve, and it uses can be suitable for all size nut by different sleeves, reaches a multiplex effect of spanner.
For realizing this technical purpose, the technical solution adopted in the utility model is: the ratchet spanner of a kind of interchangeable sleeve, including handle and sleeve, is provided with ratchet in the middle part of described sleeve, and described handle front end is provided with ratchet；Described ratchet is bolted to connection on handle, and ratchet engages with the ratchet in sleeve and is connected, there is radial clearance in the groove that described ratchet installs ratchet with handle, described ratchet side is provided with spring, and spring one end and detent contact, the spring other end and handle contact internal walls, the described handle other end offers Flos Mume flywheel, and described ratchet both sides are provided with bulge-structure.
Compared with prior art, this utility model has the advantages that the ratchet spanner of this interchangeable sleeve, and it uses can be suitable for all size nut by different sleeves, reaches a multiplex effect of spanner；Between ratchet and socket ratchet, reach at a fully engaged by the elastic force of spring of compression, and the other end of ratchet is stuck on handle, make the sleeve can only one-directional rotation；When changing sleeve, as long as taking off bolt, making ratchet exit cavity, sleeve is the most conveniently replaced, is provided with bulge-structure in ratchet both sides, is used for fixing the position of sleeve, makes sleeve to move radially, and stable sleeve can allow ratchet spanner more laborsaving；Simple to operate, practical, it is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Figure of description 1-3, in this utility model embodiment, the ratchet spanner of a kind of interchangeable sleeve, including handle 1 and sleeve 2, in the middle part of described sleeve 2, it is provided with ratchet 3, described handle 1 front end is provided with ratchet 4；Described ratchet 4 is fixedly connected on handle 1 by bolt 5, and ratchet 4 engages with the ratchet 3 in sleeve 2 and is connected；There is radial clearance in the groove that ratchet installed by described ratchet 4 and handle 1；Described ratchet 4 side is provided with spring 6, and spring 6 one end contacts with ratchet 4, spring 6 other end and handle 1 contact internal walls；Described handle 1 other end offers Flos Mume flywheel 7；Described ratchet 3 both sides are provided with bulge-structure 8.
The ratchet spanner of this utility model interchangeable sleeve is at handle 1 head, ratchet 4 is connected with the groove installing ratchet 4 by bolt 5, gap is there is between ratchet 4 and groove, and enough allow ratchet unload, the opposite side of ratchet 4 places spring 6, during work, compression spring 6 makes ratchet 3 at a fully engaged with ratchet 4, it is provided with bulge-structure 8 in ratchet 3 both sides, and bulge-structure 8 is used for fixing the position of sleeve 2, when changing sleeve 2, take off bolt 5, make ratchet 4 deactivate face, ratchet 4 no longer props up 3, ratchet, and ratchet 3 can conveniently be dismantled；As long as it is certain to manufacture sleeve 2 outside dimension, endoporus is suitable for different size nut, by changing different sleeves 2 so that it is reach to be suitable for the ratchet spanner of all size nut.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent and improvement made above example according to technical spirit of the present utility model, within should be included in the protection domain of technical solutions of the utility model.
