Fast device damage is bigger, or even scraps.
Utility model content
In order to solve to extract retarder by force by tool violence in the prior art, big, operation that there are labor intensity of workerss is not
Convenient, the problem of retarder damage is bigger or even scraps, the utility model provide a kind of safety-type worm type of reduction gearing and take
Tool is used out.
To achieve the goals above, the utility model uses following technical scheme:
A kind of safety-type worm type of reduction gearing taking-up tool, including driver plate, mandril and fixing bolt, the center of driver plate
Corresponding with the installation axle of worm type of reduction gearing and perforative first threaded hole is offered, in the driver plate of the first threaded hole surrounding
On offer several perforative second threaded holes, fixing bolt passes through the second threaded hole setting on driver plate and slows down in worm and gear
On device, mandril is spirally connected and extends the installation axle of the first threaded hole and worm type of reduction gearing and is oppositely arranged.
When the utility model at work, the mounting hole for being suitble to the retarder is first found on driver plate, it will using fixing bolt
Together with driver plate is securely fixed with retarder, it is ensured that the first threaded hole is corresponding with the installation axle of worm type of reduction gearing.Then
Mandril is spirally connected in the first threaded hole, mandril is rotated, by the threaded function on mandril by mandril constantly to worm and gear
The direction of the installation axle of retarder is mobile, and under the action of mandril, retarder and axis are separated.
Further, the mandril is equipped with chuck, the mandril in one end of the installation axle far from worm type of reduction gearing
It is integrally formed with chuck.The setting of chuck is easy to use tool to carry out spinning in and out to mandril, improves efficiency.
Further, the cross section of the chuck is polygon.It can be selected as triangle, quadrangle according to actual needs
Or pentagon etc..
Further, the chuck offers auxiliary rotating handle on the end face far from mandril.The effect for assisting rotating handle is to work as
When chuck causes chuck and tool that slipping phenomenon occurs since knob power is excessive, it can be cooperated by auxiliary rotating handle and tool to top
Bar carries out spinning in and out.
Further, second threaded hole is equipped with 8 groups, and 8 group of second threaded hole is in rice by the center of circle of the first threaded hole
Font is distributed on driver plate.Increase the quantity of the second threaded hole, convenient for fixing driver plate and retarder quickly through fixing bolt
Together.
Further, the fixing bolt at least 3.3 fixing bolts, which form triangle, can make driver plate more steady
Fixed is fixed on retarder.
The utility model has the beneficial effect that compared with prior art
The utility model first finds the mounting hole for being suitble to the retarder on driver plate, using fixing bolt by driver plate and deceleration
Device securely fixes together, it is ensured that the first threaded hole is corresponding with the installation axle of worm type of reduction gearing.Then mandril is spirally connected
In the first threaded hole, mandril is rotated, by the threaded function on mandril by mandril constantly to the peace of worm type of reduction gearing
The direction for filling axis is mobile, and under the action of mandril, retarder and installation axle are separated.Realizing can easily, conveniently, efficiently
It is separated to what retarder and installation axle did not damage.

Specific embodiment
Below with reference to embodiment, the utility model will be further described, and described embodiment is only that this is practical new
Type a part of the embodiment is not whole embodiment.Based on the embodiments of the present invention, the ordinary skill people of this field
Member's other embodiments used obtained without making creative work, belong to the protection model of the utility model
It encloses.
Embodiment 1:
As shown in Figure 1, a kind of safety-type worm type of reduction gearing takes out the tool of using, including driver plate 2, mandril 3 and fixed spiral shell
Bolt 7, the center of driver plate 2 offer first threaded hole 8 corresponding and perforative with the installation axle 6 of worm type of reduction gearing 1,
Several perforative second threaded holes 9 are offered on the driver plate 2 of one threaded hole, 8 surrounding, in the present embodiment, the second threaded hole 9 is set
There are 8 groups, and 8 group of second threaded hole 9 is that the center of circle is distributed on driver plate 2 in rice font with the first threaded hole 8, as shown in Figure 2.Increase
The quantity of second threaded hole 9, convenient for making driver plate 2 and retarder 1 be fixed together quickly through fixing bolt 7.Fixing bolt 7 is worn
The second threaded hole 9 on driver plate 2 is crossed to be arranged on worm type of reduction gearing 1, mandril 3 be spirally connected and extend the first threaded hole 8 with
The installation axle 6 of worm type of reduction gearing 1 is oppositely arranged.The fixing bolt 7 of the utility model at least 3.3 fixing bolts 7
Forming triangle can make driver plate 2 more be stably fixed on retarder 1.
The mandril 3 of the utility model is equipped with chuck 4, the top in one end of the installation axle 6 far from worm type of reduction gearing 1
Bar 3 and chuck 4 are integrally formed.The cross section of the chuck 4 of the utility model is polygon.It can be selected as three according to actual needs
Side shape, quadrangle or pentagon etc..
When the utility model at work, the mounting hole for being suitble to the retarder 1 is first found on driver plate 2, use fixing bolt 7
Together with driver plate 2 is securely fixed with retarder 1, it is ensured that the first threaded hole 8 is opposite with the installation axle 6 of worm type of reduction gearing 1
It answers.Then mandril 3 is spirally connected in the first threaded hole 8, rotates mandril 3, it is by the threaded function on mandril 3 that mandril 3 is continuous
Direction from the installation axle 6 to worm type of reduction gearing 1 it is mobile, under the action of mandril 3, retarder 1 and installation axle 6 are divided
