Fig. 5 is the diagrammatic cross-section of the decoder shown in Fig. 1, refers to Fig. 1 and Fig. 5, during installation, first by decoder main body
21 install, it is necessary to positioned to the bearing 211 of decoder main body 21, then, flange 12 are sheathed on axle 11 so that method
The sleeve 122 of orchid 12 is contained in the groove 111 of axle 11, and the flange 121 of flange 12 is posted by bearing 211, but not to bearing 211
Apply active force；Then, nut 13 is threadedly coupled with the sleeve 122 of flange 12 in a manner of right-handed thread connects, then by spiral shell
Line connection component 14 is threadedly connected on sleeve 122, because the internal thread of the screwed hole 161 of base 16 is levogyrate inner thread, bottom
Seat 16 is threadedly coupled using left hand thread with sleeve 122, and the part of supporting piece 18 is inserted in the storage tank 132 of nut 13,
Under the elastic force effect of spring 17, inclined plane and the inclined plane in storage tank 132 of supporting piece 18 offset.Due to nut 13 and spiral shell
Line connection component 14 is threadedly coupled with the sleeve 122 of flange 12, and nut 13 and screwed assembly 14 can be received to a certain extent
Tight set cylinder 122, the setting of the breach 123 on sleeve 122 can facilitate sleeve 122 to be tightened up to center, so as to which sleeve 122 can hold axle tightly
11。
In the course of work, when decoder 20 vibrates repeatedly, right-handed thread is used between the sleeve 122 of nut 13 and flange 12
Connection, when nut 13 is by revolving force to the left, the meeting relative sleeve 122 of nut 13 loosens；Due to supporting for screwed assembly 14
The storage tank 132 of part 18 and nut 13 offsets, when nut 13 is by revolving force to the left, screwed assembly 14 also accordingly by
Revolving force to the left is arrived, and is connected between screwed assembly 14 and the sleeve 122 of flange 12 using left hand thread, screwed assembly
14 by revolving force to the left when, what can be spirally connected with sleeve 122 is tighter, and whole screwed assembly 14 moves to the side of nut 13, supports
The active force that gripping member 18 is held in the inwall of 13 storage tank of nut 132 is bigger, can prevent nut 13 from, to anticlockwise, avoiding nut 13
Loosen, nut 13 is close proximity on the flange 121 of flange 12, it is ensured that the position of flange 121 is motionless；Due to flange 121 and decoding
The bearing 211 of device main body 21 reclines, and the position of flange 121 is motionless can to position bearing 211.
It should be noted that in the present embodiment, being connected between nut 13 and sleeve 122 using right-handed thread, it is threadedly coupled
Connected, can used in other embodiments, between nut 13 and sleeve 122 left-handed using left hand thread between component 14 and sleeve 122
Threaded connection, correspondingly, is connected between screwed assembly 14 and sleeve 122 using right-handed thread；In this case, nut 13
During by revolving force to the right, the meeting relative sleeve 122 of nut 13 loosens；When nut 13 is by revolving force to the right, because screw thread connects
The supporting piece 18 of connected components 14 offsets with the storage tank 132 of nut 13, and screwed assembly 14 is also accordingly by right rotation
Power, and connected between screwed assembly 14 and the sleeve 122 of flange 12 using right-handed thread, screwed assembly 14 is by the right
During revolving force, what can be spirally connected with sleeve 122 is tighter, and whole screwed assembly 14 moves to the side of nut 13, and supporting piece 18 supports
It is bigger in the active force of the inwall of 13 storage tank of nut 132, it can prevent nut 13 from, to anticlockwise, avoiding nut 13 from loosening, flange
The position of 12 flange 121 is motionless, so as to realize the positioning to bearing 211.
The structure of screwed assembly 14 is not limited with the embodiment shown in Fig. 3, but needs to meet：Screwed assembly 14 to
Small part is contained in storage tank 132 and is held in the inwall of storage tank 132, and is used between screwed assembly 14 and flange 12
Threaded connection, for example, in other embodiments, spring 17 can omit, base 16 and supporting piece 18 are integrally formed.
The present invention also provides a kind of encoder, and the encoder includes above-mentioned tool locating structure 10, tool locating knot
Structure 10 can position to the bearing of encoder.
The present invention proposes a kind of motor again, and the motor includes above-mentioned encoder or decoder 20, tool locating structure
10 can position to the bearing of motor.
It should be noted that the application of the tool locating structure 10 of the present invention is not with decoder 20, encoder and electricity
