Ball orbit groove 6-6 structure and the course of work may be referred to a kind of patent of invention " drawing and pulling type spiral module " (Shen
Please number：201610586990.0) description in, does a briefly introduction herein：As shown in Fig. 4, Fig. 6, Fig. 7, ball orbit groove
6-6 includes the locking track, connection track and circular orbit of connection combination, and three kinds of tracks are fluted body.In the association of upper lid 11
Under same-action, ball 10 is rolled in three kinds of tracks, carries out locking or the unblock of runner 6.
Circular orbit sets two, respectively positioned at the both sides up and down of wind spring accommodating chamber 6-3 outer circumference surface, locking track,
Connection track is respectively provided with more than two, and alternating is distributed between two circular orbits, connects two circular orbits；Circular orbit point
To reclaim track and drawing trajectory, the height for reclaiming track is less than drawing trajectory.
Locking track in "<" type, it is divided into locking track and lower locking track, utilizes corner's locking ball.
It is in bias type to connect track, and incline direction is consistent with lower locking orbital direction.
From the bottom up, ball successively along lower circular orbit, lower locking track, upper locking track, upper circular orbit list
To rolling.From top to bottom, ball successively along upper circular orbit, connection track, lower circular orbit single roll.
Wire rod 5 is stretched out, runner 6 rotates forward and tightens up wind spring 8, ball 10 is maintained in lower circular orbit and rolled
Move, or ball 10 is entered in lower circular orbit by upper circular orbit through connecting track, and it is maintained at rolling in lower circular orbit
It is dynamic；Stop stretching wire rod 5, wind spring 8 drives runner 6 to reversely rotate, ball 10 is entered locking track by lower circular orbit and blocked
Runner 6 is prevented to invert around the corner, runner 6 is locked out.
The preset distance of wire rod 5 is stretched out again, runner 6 is rotated forward, ball 10 enters upper circular rails by locking track
In road, runner 6 is unlocked by rotation, now discharges wire rod 5, and ball 10 is maintained in circular orbit and rolled, and runner 6 is reversely rotated
Withdraw wire rod 5；Or outside continued extension wire rod 5 again, runner 6 rotates forward, and ball 10 enters upper annular by locking track
In track, and enter through connecting track in lower circular orbit, be maintained in lower circular orbit and roll, runner 6 is unlocked.
As shown in Fig. 4, Fig. 7, escape groove 6-1 is provided with wind spring accommodating chamber 6-3 inwall, the movable end of wind spring 8 is set
Have in kink, kink insertion escape groove 6-1, it is spacing by escape groove 6-1.

Clamping.
The capping of wind spring accommodating chamber 6-3 upper ports has Upper gasket 9, drives Upper gasket 9 to rotate together when runner 6 rotates.Upper pad
Piece 9 uses metal material, such as copper alloy or stainless steel.
As shown in Fig. 4, Fig. 8, wind spring is provided with Upper gasket 9 and fixes armstand 9-1, wind spring fixes armstand 9-1 insertion wind springs 8
Kink, the kink of wind spring 8 is fixed in the escape groove 6-1 on wind spring accommodating chamber 6-3 inwall.So it is achieved that
The movable end of wind spring 8 is connected with wind spring accommodating chamber 6-3 inwall, drives wind spring 8 to carry out elastic deformation when runner 6 rotates.
Wind spring fixes the vertical body of Upper gasket 9 of armstand 9-1, and it is also in arc-shaped that wind spring, which fixes armstand 9-1, can and escape groove
6-1 formation coordinates.
As shown in Fig. 4, Fig. 6, Fig. 7, wind spring accommodating chamber 6-3 upper ports are provided with stopper slot 6-2 and install Upper gasket 9, wind spring
Accommodating chamber 6-3 upper ports set stopper slot 6-2 position stepped.
Limited location otch 9-2 and stopper slot 6-2 is set to coordinate on Upper gasket 9, spacing otch 9-2 is located at wind spring and fixes armstand
9-1 both sides.So it is achieved that Upper gasket 9 is connected with runner 6, drives Upper gasket 9 to rotate together when runner 6 rotates.
Upper gasket 9 is installed into after stopper slot 6-2, and upper surface is less than wind spring accommodating chamber 6-3 upper ports, or holds with wind spring
Chamber 6-3 upper ports of receiving maintain an equal level.So design can allow the top of runner 6 not have unnecessary height, fully reduce the axial direction of spiral module
Size.
As shown in figure 8, the middle part of Upper gasket 9 is provided with centre bore 9-3, the upper end of main shaft 4 can be passed from centre bore 9-3.
As shown in Figure 2, Figure 3, Figure 4, drawing and pulling type spiral module also includes upper lid 11, and upper lid 11 is arranged on wind spring accommodating chamber 6-
3 tops, upper lid 11, which is provided with vertical elastic arm, elastic arm, is provided with guide groove, and ball 10 is provided with guide groove, elasticity
Ball 10 is clamped in ball orbit groove 6-6 by arm.
The structure and the course of work of upper lid 11 can also refer to a kind of patent of invention " drawing and pulling type spiral module " (application number：
201610586990.0) in description, be not explained herein.
Wind spring accommodating chamber 6-3 bottom is provided with lower gasket 7, and wind spring 8 is located on lower gasket 7.Lower gasket 7 uses metal material
Matter, such as copper alloy or stainless steel.Lower gasket 7 can be born during the elastic deformation of wind spring 8 to wind spring accommodating chamber 6-3 bottoms
Friction.
Embodiment 2
In this embodiment, as shown in Figure 6, Figure 7, escape groove 6-1 extends downwardly into wind spring accommodating chamber 6-3 bottom,
Groove is formed on wind spring accommodating chamber 6-3 bottom, or escape groove 6-1 penetrates downwards wind spring accommodating chamber 6-3 bottom, and wind spring is fixed
Armstand 9-1 is downwardly into wind spring accommodating chamber 6-3 bottom groove or open-work.
So design, enabling to wind spring to fix armstand 9-1 will not deviate from from escape groove 6-1, to the movable end of wind spring 8
It is spacing more firm.
The other structures of drawing and pulling type spiral module are in the same manner as in Example 1 in the present embodiment, and description is not repeated herein.
The embodiment of the present invention is these are only, under the above-mentioned teaching of the present invention, those skilled in the art can be with
