Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail.
As Figure 1-4, this utility model includes power transmission shaft 1, and it also includes axle sleeve 7, shell fragment 11, compression spring 9, spacing
Steel ball 3；Lower O-ring 2 is equipped with power transmission shaft 1, rotates against friction to reduce between power transmission shaft 1 and its upper end axle sleeve 7, with
When, reduce the radial fit gap between the two.The upper end of lower O-ring 2 is provided with compression spring 9；Compression spring 9 is three, three
Root compression spring 9 end to end formation turn successively.
Spacing steel ball 3 is three, and three spacing steel balls 3 are respectively arranged between adjacent two compression spring 9；Pressure bullet
Spring 9 is all fixed on axle sleeve 7 by spring catch 10；Spring catch 10 be arranged at the spacing steel ball 3 that compression spring 9 is adjacent it
Between.The middle setting of turn has shell fragment 11；Shell fragment 11 is nested with power transmission shaft 1；Shell fragment 11 can be to outer expansion after stress.
Axle sleeve 7 is placed on the upper end of power transmission shaft 1；Lower O-ring 2, turn are respectively arranged at the interior lower end of axle sleeve 7, interior
In the middle of portion；The inner upper end of axle sleeve 7 is provided with protecgulum 5；The inner upper end of protecgulum 5 is provided with locating ring 6；Locating ring 6 is nested with
On power transmission shaft 1, for protecgulum 5 is limited to power transmission shaft 1 in the axial direction.
One circle groove is offered on the outer wall of protecgulum 5；It is equipped with O-ring 4, upper O-ring 4 is used for reducing axle sleeve in groove
Rotate against friction between 7 and protecgulum 5, meanwhile, reduce the radial fit gap between the two.The middle setting of power transmission shaft 1 has
Fixing screws 8；Fixing screws 8 are arranged at the lower end of axle sleeve 7.
The inner side of axle sleeve 7 is provided with axle sleeve and stirs tooth 14；Axle sleeve is stirred tooth 14 and is three, and it is uniform that tooth 14 stirred by three axle sleeves
It is distributed on the inwall of axle sleeve；Axle sleeve is stirred tooth 14 and is plugged between the spacing steel ball 3 that compression spring 9 is adjacent；
The first stopper slot 12, the second stopper slot 13 is all offered on the axle sleeve 7 that adjacent axle sleeve is stirred between tooth 14；Axle sleeve
Stir tooth 14, the first stopper slot 12, the second stopper slot 13 successively by arranged clockwise.
In locking state, three spacing steel balls 3 are separately mounted in three the first stopper slots 12 this utility model, spacing
Steel ball 3 is limited jointly by compression spring 9, spring catch 10, shell fragment 11；Now, connect between accessory and protecgulum 5, spacing steel ball 3 with
Mutual asphyxia by external pressure on the chest and abdomen between protecgulum 5, between spacing steel ball 3 and power transmission shaft 1, very close to each other, thus accessory clamping will be connected；Now,
If directly connection accessory is pulled up from this device extremely difficult；
To pull down connecting accessory from this device, only axle sleeve 7 need to be rotated counterclockwise.To counterclockwise
During the rotary axle box 7 of direction, spacing steel ball 3 is because by protecgulum 5 and power transmission shaft 1 asphyxia by external pressure on the chest and abdomen, it is impossible to mobile, meanwhile, shell fragment 11 is dialled in axle sleeve
The promotion lower stress of dynamic tooth 14 opens, and chokes spacing steel ball 3 further.Therefore, after axle sleeve 7 rotation, spacing steel ball 3 and axle sleeve 7
Between radial clearance increase, shell fragment 11 outwards struts spacing steel ball 3 so as to drop into the second limit in the first stopper slot 12
In the groove 13 of position；Now, produce gap between protecgulum 5 and spacing steel ball 3 in the axial direction, then protecgulum 5 is connecting the work of accessory
With under (because protecgulum 5 be connected very tight before accessory, axial gap asphyxia by external pressure on the chest and abdomen), can be in the axial direction to leaving the side connecting accessory
To movement, so thus loosen therebetween, connecting accessory can easily unload, and reach the purpose of fast quick-detach.
This utility model has quick, the easy function of dismounting, connection accessory will be led to be destroyed because dismantling.This
Outward, this utility model have the advantages that structure simple, easy to use, stable and reliable for performance it is adaptable to various connection accessories fast
Quick-detach.
Above-mentioned embodiment is not to restriction of the present utility model, and this utility model is also not limited to the example above,
Change, remodeling, interpolation or replacement that those skilled in the art are made in the range of the technical solution of the utility model,
Also belong to protection domain of the present utility model.
