Description

A kind of small wrench
Technical field
It the utility model is related to machine tool technical field, more particularly to a kind of small wrench.
Background technology
Spanner is a kind of conventional installation and extracting tool.Bolt, screw, nut and other spiral shells are twisted using lever principle Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is generally formed with clamping in the one or both ends of shank The opening or sets of holes of bolt or nut, threadingly direction of rotation applies external force in shank during use, with regard to that can twist bolt or nut.
Existing spanner structure is single, although different use heads can be changed constantly, structure is relatively fixed, it is impossible to Flexibly low arbitrarily assembling is used cooperatively.Meanwhile spanner design at present does not have inadequate hommization, it is not possible to carries with.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of small pull Hand, it is convenient for carrying, structure assembling is various, flexible and changeable, and convenient operation, using hommization, operating efficiency is high, saves the time, can Fully to meet the use of outdoor exercises person and mechanical user.
To achieve the above object, the utility model provides a kind of small wrench, it is characterised in that:Including replaceable head, low Head cylinder card, cylindrical drum card, main component, head, unilateral bearing, bearing card holder can be carried, the main component left and right directions is installed respectively One cylindrical drum card, the main component top installation can carry head, unilateral bearing, the one-way shaft installed inside the main component Hold and cylinder card of bowing is installed by bearing card holder.
A kind of above-mentioned small wrench, it is characterised in that:Replaceable head is installed on the cylinder card of bowing, cylindrical drum card.
A kind of above-mentioned small wrench, it is characterised in that:The head that carries is cube structure.
A kind of above-mentioned small wrench, it is characterised in that:Of different sizes interior six are set on six faces for carrying head Rib side.
A kind of above-mentioned small wrench, it is characterised in that:The unilateral bearing installs cylindrical drum card by bearing card holder.
A kind of above-mentioned small wrench, it is characterised in that:Installation can carry head on the cylindrical drum card.
The beneficial effects of the utility model are:
The utility model is convenient for carrying, and structure assembling is various, flexible and changeable, convenient operation, uses hommization, operating efficiency Height, the time is saved, can fully meet the use of outdoor exercises person and mechanical user.
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of as shown in figure 1, small wrench, it is characterised in that:Including replaceable first 1, cylinder card 2 of bowing, cylindrical drum card 3, master Body part 4, first 5, unilateral bearing 6, bearing card holder 7 can be carried, the left and right directions of main component 4 installs a cylindrical drum card 3 respectively, The top of main component 4 installation can carry first 5, and the inside of the main component 4 installation unilateral bearing 6, the unilateral bearing 6 passes through axle Hold card holder 7 and cylinder card 2 of bowing is installed.
In the present embodiment, replaceable first 1 is installed on the cylinder card 2 of bowing, cylindrical drum card 3.
In the present embodiment, described to carry first 5 be cube structure.
In the present embodiment, described carry sets interior six rib side of different sizes on first 5 six faces.
In the present embodiment, the unilateral bearing 6 installs cylindrical drum card 3 by bearing card holder 7.
First 5 can be carried by being installed in the present embodiment, on the cylindrical drum card 3.
Operation principle of the present utility model is:
It can be used cooperatively after being installed using replaceable first 1 on cylinder card 2 of bowing, cylindrical drum card 3, meet the spirit of spanner Usability living.Unilateral bearing 6 is unidirectionally used when can be fastened using its one-way to cylinder card 2 of bowing with replaceable first 1.It can take Taking the lead 5 can be used cooperatively with main component 4, can also be carried with, can carry set on first 5 six faces it is of different sizes Interior six rib side, to be fastened to different screws, it can be used using the narrow and small place of spatial dimension.Cylindrical drum card 3 can also It is used cooperatively with unilateral bearing 6, meets the flexibility of spanner.
The utility model is totally divided into three parts, and Part I is main component 4, secondly internal to be provided with unilateral bearing 6, meets The tightness of its single direction;Part II is cylindrical drum card 3, and it can be engaged with main component 4, also can be with itself phase interworking Close, in narrow and small elongated space, increase it and use length;For that can carry first 5, it is used cooperatively Part III with main component 4, Also can be used cooperatively with cylindrical drum card 3, and itself is individually used, and can be used in the minimum space of scope, and easily Can portable.
Be provided with main component 4 for install cylindrical drum card 3, can carry first 5 square groove, cylindrical drum card 3, can carry First 5 and the installation end of main component 4 be square spigot, the square groove cooperation with main component 4.Inside the other end of cylindrical drum card 3 Square groove is set, first 5 can be carried available for installation or continue that next extension length of cylindrical drum card 3 is installed.
Sum it up, the utility model can arbitrarily adjust use, lengthening or single use in different spatial dimensions, make With flexible, convenient.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area Member makes many modifications and variations without creative work can according to design of the present utility model.Therefore, all this technology necks Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
