2 are installed together；When movable junction is located at the second position, movable junction is separated with guiding walls 152, the first location structure 15
It is separated with the second location structure 24, sleeve assembly 1 and driving assembly 2 separate.
Shown in Figure 6, movable junction is steel ball 242, and moving member 243, and tool in protrusion 241 are equipped in protrusion 241
There is 243 mobile space of moving member, protrusion 241 is radially provided with the accommodation groove 244 of perforation, and one end of accommodation groove 244 extends to protrusion
241 outer walls, 244 other end of accommodation groove are connected to mobile space, and steel ball 242 moves radially in accommodation groove 244 and steel ball 242
Do not deviate from accommodation groove 244, and the inner and outer wall of protrusion 241, moving member can be moved and partially protruded from accommodation groove 244
243 can push steel ball 242 to protrude from raised 241 outer walls and steel ball 242 is kept to be held in guiding walls 152.Moving member 243 is in movement
When space is mobile, moving member 243 pushes steel ball 242 to protrude from raised 241 outer walls, and steel ball 242 is held in guiding walls 152.Wherein,
The cell wall of accommodation groove 244 can be arc, and the diameter of 244 liang of mother rib lateral rotundums of accommodation groove is less than the maximum gauge of steel ball 242, prevents steel ball
242 abjection accommodation grooves 244, while make again steel ball 242 can partially protrude from protrusion 241 inner and outer wall.Similarly, other two
The slotted hole structure that side opening is less than 242 maximum gauge of steel ball can also be used as the structure of accommodation groove 244.
It is connected automatically when the first location structure 15 and the second 24 male-female engagement of location structure to realize, the second location structure
24 further include the cylinder barrel 245 connecting with protrusion 241, and cylinder barrel 245 passes through piping connection air feeder, air supply
Device connects controller, and controller controls the air inlet and outlet cylinder cylinder 245 of air feeder；Distinguish at the both ends of moving member 243
In protrusion 241 and cylinder barrel 245, moving member 243 is located at one end in cylinder barrel 245 with sliding with 245 inner wall of cylinder barrel
Move the piston head 246 of connection；The side that moving member 243 is located in cylinder barrel 245 is set with second spring 247, second spring
247 between 245 wall of cylinder barrel and piston head 246.Specifically, referring to Fig. 6, after piston head 246 is located at moving member 243
End, the front of moving member 243 have voussoir and positioned at the pushing parts of voussoir front end, and the cross section of voussoir from back to front is gradually increased
To identical as the cross section of pushing part, the cross section of pushing part is constant, and raised 241 inner walls are close in pushing part.
Wherein, the first location structure 15 and the connection of the second location structure 24 and the isolated course of work are as follows:
When protrusion 241 is inserted into groove 151, second spring 247 is in compressive state, and controller controls in cylinder barrel 245
Air returning air feedway, under the action of 247 elastic force of second spring, moving member 243 is moved back, voussoir with moving back,
The state that the side wall of voussoir never contacts steel ball 242 slowly protrudes from protrusion by promotion to steel ball 242, steel ball 242 is slowly contacted
241 outer walls, with moving back for moving member 243, when steel ball 242 is contacted with pushing part, the cross section of pushing part is constant, keeps steel
The position of ball 242 is constant, so that steel ball 242 be kept persistently to be held in guiding walls 152, and then realizes the first location structure 15 and the
Two location structures 24 are fixedly connected, and the output end and interconnecting piece 121 of drive shaft 22 are mating, and sleeve assembly 1 is installed to drive
On dynamic component 2, docking is sent close to switch 25 and completes signal to controller.
When the needs of sleeve assembly 1 are separated with driving assembly 2, it is defeated to cylinder barrel 245 that controller controls air feeder
Air is sent, moving member 243 moves forward, and voussoir is separated with Forward, the side wall of voussoir with steel ball 242, the locking of steel ball 242 is released,
Groove 151 and protrusion 241 separate, so that sleeve assembly 1 and driving assembly 2 separate.
It is shown in Figure 7, provide a kind of drive sleeve 12 and schematic cross-section when drive shaft 22 connects, drive shaft 22 it is defeated
