Description
Technical field
The utility model is related to hardware tool, more particularly to a kind of reversed power-assisted screwdriver.
Background technology
In the actual work, it is frequently encountered screw difficulty in the work of dismounting mechanical equipment and unloads problem, especially exist
It is more difficult in the case of one word or cross notch are incomplete to unload, if it is the more to unload the more poor to continue to twist by force, encounters and become rusty for a long time
It is also unusual difficulty that the screw of erosion, which is removed, often helpless, needs that technical professional is looked for tear open using specific purpose tool
It removes, can even generate damage to equipment sometimes.
Invention content
The purpose of this utility model is to propose a kind of reversed power-assisted screwdriver, utilizes setting sliding block and a band in casing
There is spiral shell button stress round bar to be mutually fitted, stress round bar is connect with driver bit, drives driver bit to rotate backward by ramming pipe
Realize the dismounting for tearing screw open to hardly possible.
To achieve the goals above, the technical solution of the utility model is：A kind of reversed power-assisted screwdriver, including stress circle
The front end of bar, stress round bar is screwdriver connector, wherein circumferentially surface is provided with and the screw of being unloaded the stress round bar
The identical spiral notch in spiral shell button direction of rotation, the spiral angle of spiral notch is not less than 45 degree, and a handle sleeve is sleeved on
On the stress round bar, it is provided with boss slider on the handle sleeve madial wall, boss slider is caught in spiral notch, is unloaded
When screw, driver bit is caught in after screwdriver connector to notch driver bit withstood on the screw terminal for wanting removal screw
In, grasp taper knob and do not turn, using hammer handle sleeve top, on handle sleeve madial wall circular arc boss slider to
Under move compressing stress round bar along spiral notch and reversely rotated along to unload screw precession direction, screw is screwed out.
Scheme is further：The stress round bar includes a metal sleeve and a solid metal, solid metal
It is inserted into metal sleeve to be fixedly connected, the front end of metallic rod is provided with screwdriver connector, sets in described sleeve pipe upper edge circumferential surface
It is equipped with the backpitch notch opposite with the screw socket direction of rotation for the screw of being unloaded.
Scheme is further：The handle sleeve includes inner and outer tubes, and open-work is provided in said inner tube, uses circle
Cylinder is inserted into open-work and forms the boss slider, and said inner tube is nested with outer tube and is fixedly connected.
Scheme is further：The handle sleeve outer surface is provided with anti-skidding prismatic or groove.
Scheme is further：The backpitch notch is arranged one or continuous more along the stress round bar circumferential surface
Item, at least two pieces of the boss slider, two pieces of boss slider opposite faces are arranged in the stress round bar backpitch notch.
The advantageous effect of the utility model compared with prior art is：Special purpose machine tool processing is not needed, it is hand-made simple,
It is not only applicable to the dismounting of the screw of a word or cross notch, the dismounting of interior side's screw, behaviour are applied also for after replacement driver bit
Make simple, success rate height, does not need special technical training.
The utility model is described in detail with reference to the accompanying drawings and examples.
Description of the drawings
Fig. 1 is the utility model structural profile illustration；
Fig. 2 is the usage state diagram after the utility model assembling.
Specific implementation mode
A kind of reversed power-assisted screwdriver, as shown in Figure 1, the reversed power-assisted screwdriver includes stress round bar 1, stress round bar
Front end be screwdriver connector 2, wherein the stress round bar circumferentially surface be provided with the spiral shell button for the screw of being unloaded rotation
The spiral angle a of the identical spiral notch 101 in direction, spiral notch is not less than 45 degree, between 45 degree to 60 degree, this implementation
Really 50 degree of example, a handle sleeve 3 is sleeved on the stress round bar 1, is provided on 3 madial wall of the handle sleeve convex
Sliding block 4 is played, boss slider 4 is caught in spiral notch 101, when unloading screw, is connected as shown in Fig. 2, driver bit 5 is caught in screwdriver
Driver bit is withstood in the notch on the screw terminal for wanting removal screw after interface 2, taper knob is grasped and does not turn, use hammer
Handle sleeve top 301 is struck, since taper knob does not turn, boss slider 4 is downwards along spiral notch on handle sleeve madial wall
Movement can oppress stress round bar along to unload the reverse rotation of screw precession direction, and screw is screwed out.
In order to easy to make, without upper lathe skilled worker, but use and made by hand of existing parts, the present embodiment makes
With a preferred scheme：As shown in Figure 1, the stress round bar 1 includes a metal sleeve 102 and a solid metal
103, metal sleeve 102 and solid metal 103 are all easy to find in some waste and old components, and solid metal is inserted into metal
Casing is fixedly connected, using welding or riveting；The front end of metallic rod is provided with screwdriver connector, and connector is an a variety of works
The connector of tool is suitable for the screwdriver etc. of square nut, before solid metal is inserted into metal sleeve, in described sleeve pipe
Circumferentially surface hacksaw and file processing according to open, be rasped to file circular arc be arranged to be formed with the screw socket rotation side for the screw of being unloaded
To opposite spiral notch, this is very easy for general pincers worker, and solid metal 103 is then being inserted into fixation.
Equally：As shown in Figure 1, the handle sleeve includes inner tube 301 and outer tube 302, it is thus processing handle sleeve 3
It is provided with boss slider 4 on madial wall to bring conveniently, open-work is provided with by drilling in said inner tube, first by stress round bar
It reuses cylinder insertion open-work after 1 insertion to be welded and fixed to form the boss slider, then by said inner tube and outer tube phase
Set is fixedly connected to form an integral handle casing 3.Its rotation is prevented since handle sleeve 3 needs to hold, in embodiment：
The handle sleeve outer surface is as shown in Fig. 2, be provided with anti-skidding prismatic or groove 302.
Wherein, in the stress round bar 1, circumferentially the spiral notch 101 of surface setting can be arranged in half periphery
One or axially disposed a plurality of, or it is arranged one or more in complete circumferential surface, that is：The spiral shell
Stress round bar circumferential surface described in spin slot opening's edge is arranged one or continuous a plurality of, correspondingly, the boss slider at least two
Block, two pieces of boss slider opposite faces are arranged in the stress round bar backpitch notch, and evenly, effect is more preferable for such stress.
