Utility model content
In view of the above technical problems, the utility model provides one kind and moving back pin mechanism.
One kind moving back pin mechanism, including：
The body of rod drives the rotation of its own by artificial or machine；
First end is fixedly connected with the body of rod, first end inner hollow, which is provided with one group it is axially right about the body of rod
The strip hole of title；
One rotation section a comprising threaded portion and a fixed part, the fixed part are placed in inside first end, pass through one
The connection of axis pin the realization rotation section and first end of above-mentioned strip hole and the fixed part is penetrated through simultaneously；The threaded portion is set
There is external screw thread.
Preferably, first end is integrally formed or welds with the body of rod.
Preferably, the outer end face of the first end extends the second end, is formed between first end and the second end
One ring ladder.
Preferably, the strip hole is ellipticity；The long axis of strip hole and the axis of the body of rod form an acute angle；The length
The tooth in angle and threaded portion external screw thread that the long axis and body of rod axis in hole are formed is consistent with the angle that body of rod axis is formed.
The utility model provides one kind and moving back pin mechanism, and rotation section is placed in first end by axis pin, and rotation section turns
It is dynamic, by axle sleeve precession wall or other be used to carry in the object of axle sleeve, when moving back pin, the second end withstands axle sleeve, and rotation section is returned
Rotation, realization move back pin, will not take axle sleeve out of, and mechanism can be used for lathe manually, can disposably complete whole flow process,
It avoids doing over again.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment：
Shown in Fig. 2 to 4, the utility model includes：The body of rod 1 drives the rotation of its own by artificial or machine；The body of rod 1
It is typically secured on lathe, or passes through manual rotation.
First end 2 is fixedly connected with the body of rod 1,2 inner hollow of first end, which is provided with one group about 1 axis of the body of rod
To symmetrical strip hole 22；First end 2 and the body of rod 1 can be integrally formed, and can also be welded together, and guarantee is fixedly connected i.e.
It can.
One rotation section 3 a comprising threaded portion 31 and a fixed part 32, fixed part 32 is equipped with through-hole 34, described solid
Determine portion 32 to be placed in inside first end 2, penetrates through the pin of 32 through-hole 34 of above-mentioned strip hole 22 and the fixed part simultaneously by one
Axis 33 realizes the connection of rotation section 3 and first end 2；The threaded portion 31 is equipped with external screw thread.
The outer end face of the first end 2 extends the second end 21, and one is formed between first end 2 and the second end 21
Ring ladder.
The strip hole 22 is ellipticity；The long axis of strip hole 22 forms an acute angle with the axis of the body of rod 1；The strip
The angle one that the tooth on 31 external screw thread of angle and threaded portion that the long axis and 1 axis of the body of rod in hole 22 are formed is formed with 1 axis of the body of rod
It causes.
Implementation principle：Axle sleeve is as shown in Figure 1, the threaded portion 31 of itself and rotation section 3 coordinates precession wall, the second end at this time
21 withstand axle sleeve, rotate backward the body of rod 1, and first end 2 is driven to circle round, and in the moment of rotation, the second end 21 withstands axle sleeve, turn
Dynamic portion 3 is moved in convolution, axis pin 33 in the body of rod 1 in strip hole 22, and mobile route is consistent with the route that rotation section 3 is turned round,
Can easily rotation section 3 and axle sleeve be detached from after the loosening of the threaded portion 31 and axle sleeve of rotation section 3, rotation section 3 loosen by realizing,
Pin is moved back in realization.
The utility model provides one kind and moving back pin mechanism, and rotation section 3 is placed in first end 2 by axis pin 33, rotation
Portion 3 rotates, by axle sleeve precession wall or other be used to carry in the object of axle sleeve, when moving back pin, the second end 21 withstands axle sleeve, turns
Dynamic portion 3 circles round, and pin is moved back in realization, will not take axle sleeve out of, mechanism can be used for lathe manually, can disposably complete whole
A flow avoids doing over again.
Various modifications to these embodiments will be apparent to those skilled in the art, herein
Defined General Principle can be real in other embodiments without departing from the spirit or scope of the present utility model
It is existing.
