21 one end, and hook portion 22 can be vertically arranged with bar portion 21.
Shank drive division 3 is arranged for driving 2 opposing substrate 1 of shank and rotates, to change hook portion 22 relative to substrate 1
Position, so that hook portion 22 is suitable for being moved to the position for hooking and holding part 20 to be removed, for example, when mobile shank drive division 3, hook
Bar drive division 3 promotes shank 2 to rotate, in this way, the hook portion 22 of 2 one end of shank can catch on part 20 to be removed, in order to
When pulling shank 2, hook portion 22 can drive part 20 to be removed to move together, so that by part 20 to be removed from target parts (example
Such as the rear end of motor 30) on disassemble.
Further, since bar portion 21 is rotatably connected on substrate 1, therefore distance of the hook portion 22 away from part 20 to be removed is adjustable
Section, thus can make the extracting tool 10 of the utility model meet the part to be removed 20 of different dimensions, so as to improve dismounting
The versatility of instrument 10.
Substrate drive division 4 is arranged for drive substrate 1 and drives shank 2 to be translatable along the axial direction of substrate drive division 4.Change speech
It, operator can be made drive substrate 1 drive shank 2 to move, under the action of shank 2, be treated by operation substrate drive division 4
Synchronizing moving occurs for demolition part 20, thus can realize the dismounting of part 20 to be removed.
Below exemplified by dismantling splined shaft 201 using the extracting tool 10 of the utility model, illustrate making for extracting tool 10
Use process.As shown in Fig. 2, raised circle 202 is provided with the length direction of splined shaft 201, and raised circle 202 and splined shaft 201
It is fixedly linked, when dismantling splined shaft 201 using the extracting tool 10 of the utility model, the hook portion 22 of shank 2 catches on raised circle
202 lower face, and the upper surface of hook portion 22 and the lower face of raised circle 202 fit closely, and substrate drive division 4 withstands on motor
On 30 rear end face (i.e. upper surface in Fig. 2), operator adjusts substrate drive division 4 manually, can make substrate 1 drive shank 2,
Shank 2 drives raised circle 202 together along the axial to the direction translational away from motor 30 of substrate drive division 4, such as to the upper of Fig. 2
Fang Yidong, thus can be by whole substrate 1, shank 2, shank drive division 3 together with 202 outside (tops i.e. into Fig. 2) of protrusion circle
Pull, until splined shaft 201 is disassembled, it is easy to operate, time saving and energy saving.

32, regulation handle 32 is fixed on the side of the remote substrate 1 of drive division body 31, and drive division body 31 drives shank 2 with respect to base
Plate 1 rotates.With reference to shown in Fig. 1, regulation handle 32 is fixed on the upside of drive division body 31, regulation handle 32 and drive division body
It can be fixed between 31 by welding manner, operator can drive drive division body 31 synchronous by turning regulation handle 32
Movement.Alternatively, regulation handle 32 is configured to T-shape handle, and person easy to operation grips, force.
Further, drive division body 31 is truncated cone-shaped, and the shape of drive division body 31 is tapered, and drive division body 31
Miner diameter end is close to substrate 1 and bigger diameter end is away from substrate 1.With reference to shown in Fig. 2, when drive division body 31 moves downward, driving
The bigger diameter end of portion's body 31 struts the upper end of shank 2, and the middle part due to shank 2 and substrate 1 are hinged, under shank 2
End can gather, tighten, thus the lower end hook portion 22 of shank 2 can catch on splined shaft 201 protrusion circle 202, and with it is convex
The lower face for playing circle 202 fits closely, and so, the connection reliability between shank 2 and raised circle 202 is higher.
In some embodiments of the utility model, shank drive division 3 can also include：Threaded rod 33 and threaded hole, ginseng
According to shown in Fig. 3-Fig. 5, the threaded rod 33 for being provided centrally with extending towards drive division body 31 of substrate 1, drive division body 31
Be provided with towards the end face of substrate 1 with threaded rod 33 coordinate threaded hole, drive division body 31 can threadingly bar 33 move with
Change the contact position of drive division body 31 and shank 2, so that 2 opposing substrate 1 of shank rotates.Due to drive division body 31
Threadingly bar 33 moves, therefore drive division body 31 can rest on the optional position on threaded rod 33, in this way, 2 lower end of shank
It can keep specifically gathering state, so as to further increase the connection reliability between shank 2 and raised circle 202.
In addition, threaded rod 33 can also play guiding role so that the movement of drive division body 31 is relatively reliable.Pass through tune
The length of fit of whole drive division body 31 and threaded rod 33, thus it is possible to vary the distance between drive division body 31 and substrate 1, and then
Change 2 lower end of shank gathers degree, to adapt to the protrusion circle 202 of different-diameter, thus, the extracting tool 10 of the utility model
Available for the splined shaft 201 for dismantling different dimensions, the versatility of extracting tool 10 is improved.
Further, threaded rod 33 and substrate 1 are perpendicular, thus, the direction of motion of drive division body 31 by with substrate 1
Center line overlaps.Preferably, threaded rod 33 is located at the center of substrate 1, can be by welding side between threaded rod 33 and substrate 1
Formula is fixed or is integrally formed, or is fixed by screw connection manner.

Threaded hole, threaded rod 33 can threadingly hole movement be to change the contact position of drive division body 31 and shank 2, so that shank
2 opposing substrates 1 rotate.Preferably, threaded rod 33 is located at the center of drive division body 31, to ensure drive division body 31
The direction of motion is overlapped with the center line of substrate 1.Alternatively, can be consolidated between threaded rod 33 and drive division body 31 by welding manner
Determine or be integrally formed, or fixed by screw connection manner.
Alternatively, with reference to shown in Fig. 4, substrate 1 has multiple support arms 11, and multiple shanks 2 are separately positioned on multiple support arms 11
On, each shank 2 is hinged with support arm 11., can be to avoid adjacent branch by the way that substrate 1 is arranged to the form with multiple support arms 11
There is excess stock between arm 11, substrate 1 need not be arranged to completely circular structure form, so can effectively mitigate the weight of substrate 1,
Be conducive to light-weight design.
Further, substrate drive division 4 can include adjusting screw rod, and adjusting screw rod includes screw body 41 and force side
42, screw body 41 is threadedly coupled with substrate 1, and specifically with reference to shown in Fig. 1, Fig. 4, driving threaded hole is offered on each support arm 11
12, screw body 41 coordinates with driving threaded hole 12, when rotary screw body 41, thus it is possible to vary screw body 41 and substrate 1
Relative position.Force side 42 can be configured to outer-hexagonal structure, thus facilitate operator to apply the instruments such as spanner.Certainly, apply
The structure at power end 42 is not limited to outer-hexagonal, can also be flat structure of interior hexagonal structure, Double Milling etc..
Alternatively, adjusting screw rod is multiple that multiple adjusting screw rods are separately positioned on multiple support arms 11.As shown in Fig. 2, work as
After shank 2 is bonded with the lower face of the protrusion circle 202 of splined shaft 201, adjusting screw rod is rotated, splined shaft 201 can be pulled out upwards.
When using the extracting tool 10 of the utility model, same operator turns multiple adjusting screw rods, Huo Zheduo successively
A operator turns multiple adjusting screw rods at the same time, to complete the dismounting of splined shaft 201.
