Abstract
The utility model discloses a spanner that can use in narrow space, include: the flexible axle, the flexible axle overcoat is equipped with the bellows, the power input of flexible axle is connected with power device, the power take off end fixedly connected with dismouting sleeve of flexible axle, the dismouting sleeve rotates and installs in fixing sleeve, fixing sleeve fixed mounting in on the bellows. Because flexible axle and bellows can be crooked with arbitrary angle, therefore in the dismouting sleeve arranged narrow and small space in, the accessible flexible axle converted pneumatic motor's rotary power into dismouting telescopic battery temperature, drives screw or bolt or nut and rotates to realize the dismantlement or the fastening of screw or bolt or nut in the narrow space.
Description
Technical field
This utility model relates to spanner technical field, specifically, relates to a kind of spanner that can use in narrow space.
Background technology
Mostly traditional spanner is to be allowed nut fastening or demounting bolt by turning handle, spanner needs certain rotary space when rotating, but at some narrow spaces, such as modularized house is built, the inner space etc. of building machinery, spanner does not has the rotary space of abundance, it is impossible to by bolt fastening or dismounting.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of spanner that can use in narrow space.
For solving above-mentioned technical problem, the technical solution of the utility model is: the spanner that can use in narrow space, including: flexible axle, the power intake of described flexible axle connects dynamic device, the clutch end of described flexible axle is fixedly connected with dismounting sleeve, described dismounting sleeve rotates and is installed in fixing sleeve, and described fixing sleeve is fixedly installed on corrugated tube, and described bellows-sheathed is loaded on described flexible axle.
Preferably, described power set are air motor.
Preferably, the endoporus of described dismounting sleeve is tetragon or hexagon.
Preferably, described dismounting sleeve is rotated by ball roller bearing and is installed in described fixing sleeve.
Preferably, described corrugated tube is metal bellows.
After have employed technique scheme, the beneficial effects of the utility model are:
Owing to flexible axle and corrugated tube can be with arbitrarily angled bendings, therefore dismounting sleeve is placed in narrow space, by flexible axle, the power of power set can be converted to the rotation torque of dismounting sleeve, drive screw or bolt or nut to rotate, thus realize the screw in narrow space or bolt or the dismounting of nut or fastening.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the spanner that can use in narrow space of the present utility model；
In figure: 1-flexible axle；2-metal bellows；3-fixes sleeve；4-dismounts sleeve；5-ball roller bearing；6-power set.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, and is not used in restriction this utility model.
As shown in Figure 1, a kind of spanner that can use in narrow space, including flexible axle 1, metal bellows 2 it is set with on flexible axle 1, the power intake of flexible axle 1 connects dynamic device 6, the clutch end of flexible axle 1 is fixedly connected with dismounting sleeve 4, and dismounting sleeve 4 is installed in fixing sleeve 3 by two ball roller bearings rotations, and fixing sleeve 3 is fixedly installed in one end of metal bellows 2.
Wherein, the material of metal bellows 2 is preferably rustless steel.
Power set 6 may select air motor or hydraulic motor or motor, preferably air motor.
The internal via shape of dismounting sleeve 4 is suitable with the shape of screw or bolt or nut, preferably tetragon or hexagon.
When dismantling or fasten the screw in narrow space or bolt or nut, dismounting sleeve 4 is set on screw or bolt or nut, starts air motor, drive flexible axle 1 to rotate, drive dismounting sleeve 4 to rotate, thus realize screw or bolt or the dismounting of nut or fastening.Owing to flexible axle 1 and metal bellows 2 can arbitrarily angled bend, make to dismount sleeve 4 can extend in the space that conventional spanner is difficult to stretch into, simultaneously, flexible axle 1 is used to transmit the mode of power, ensure that dismounting sleeve 4 obtains enough rotation torques, it is ensured that screw or bolt or the dismounting smoothly of nut or fastening.
The above is the citing of this utility model preferred forms, and the part addressed the most in detail is the common knowledge of those of ordinary skill in the art.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation carried out based on technology of the present utility model enlightenment, also within protection domain of the present utility model.
Claims (5)
1. the spanner that can use in narrow space, it is characterized in that, including: flexible axle, described flexible shaft jacket is provided with corrugated tube, the power intake of described flexible axle connects dynamic device, the clutch end of described flexible axle is fixedly connected with dismounting sleeve, and described dismounting sleeve rotates and is installed in fixing sleeve, and described fixing sleeve is fixedly installed on described corrugated tube.
