Embodiment is substantially as shown in Figures 1 and 2：
A kind of Quick Release attachment structure, is mainly made up of fixed seat 301, flange head 302 and latch 303, is provided with fixed seat 301 logical
Hole, is provided with drive mechanism in through hole, the end of flange head 302 is stretched into and fixed by latch 303 in the through hole of fixed seat 301,
Transmission mechanism is installed in flange head 302, drive mechanism and transmission mechanism are detachably connected.
Drive mechanism is made up of drive shaft 304 and the actuating sleeve being connected in drive shaft 304 341, and transmission mechanism is by passing
Moving axis 305 and the drive sleeve 351 being connected on power transmission shaft 305 are constituted, be machined with actuating sleeve 341 and drive sleeve 351 for
Mutually circumferential spacing limiting section.The concrete form of limiting section can be spline tooth, or ratchet, or other shapes
The bulge-structure of formula.For spline is socketed and gap coordinates, interference fit on power transmission shaft 305 between drive sleeve 351 and power transmission shaft 305
Limited location set, is connected with support spring 306, the He of the drive shaft 304 between the stop collar in drive sleeve 351 and power transmission shaft 305
For spline is socketed and interference fit between actuating sleeve 341.Realized using spline circumferential spacing, gap coordinates and ensure that transmission
It is slidably connected between set 351 and power transmission shaft 305, interference fit ensure that the fixed company between drive shaft 304 and actuating sleeve 341
Connect, spline builds connection compared to common, and its strong point increases, connection is more firm, stabilization, and reduces the concentration of stress.Drive
Moving axis 304 and power transmission shaft 305 are connected with each other by the cooperation of actuating sleeve 341 and drive sleeve 351, using actuating sleeve 341 and transmission
The circumferential limiting section of set 351 is mutually spacing, is capable of achieving being rapidly separated for drive shaft 304 and power transmission shaft 305.Drive mechanism and transmission
Clutch is installed, clutch has the attacker 307 being rotatably connected in fixed seat 301, one end of attacker 307 between mechanism
Offseted with drive sleeve 351, the other end of attacker 307 is connected with bracing wire.Attacker 307 is pulled to rotate by bracing wire, attacker 307 pulls
Drive sleeve 351 is slided to depart from actuating sleeve 341, so as to realize being rapidly separated for power transmission shaft 305 and drive shaft 304, disconnects transmission.
As shown in figure 3, being machined with mounting hole in fixed seat 301, latch 303 is inserted in mounting hole and the outer wall of latch 303 reveals
In in the through hole of fixed seat 301, latch 303 is through mounting hole and mounting hole, the external part threaded connection of latch 303 are stretched out in end
There is the nut 336 for axial limiting, limiting plate 332 is fixedly connected with the latch 303.It is exposed in through hole on latch 303
Outer wall be provided with the first deep-slotted chip breaker 333, the outer wall of flange head 302 is provided with second arc corresponding with the first deep-slotted chip breaker 333
Groove 321.By the position for rotating latch 303 to adjust the first deep-slotted chip breaker 333, when the position dorsad second of the first deep-slotted chip breaker 333
When deep-slotted chip breaker 321 overlaps, latch 303 is located in the second deep-slotted chip breaker 321, realizes the spacing of flange head 302, flange head 302 and solid
Reservation 301 cannot be separated；When the first deep-slotted chip breaker 333 and the second deep-slotted chip breaker 321 overlap, flange head 302 departs from the limit of latch 303
Position, enables flange head 302 and fixed seat 301 easily to separate, and realizes dismounting, and the structure operation is efficient and convenient, spacing accurate.Limit
Position plate 332 is provided with ball recess, and fixed seat 301 is provided with blind hole, blind hole and is provided with limit spring 335 and limit from bottom to up
Position ball 334.Spacing ball 334 is pushed against under the support of limit spring 335 to limiting plate 332, when rotation latch 303 to ball recess
When being overlapped with spacing ball 334, certain positioning action can be played to latch 303, prevent latch 303 from rotating.The upper end of latch 303
It is provided with handle 331.It is easy to user to hold to take, the convenient latch 303 that swings manually is rotated.
The implementation process of the structure：During installation, latch 303 is rotated by handle 331, make the first arc on latch 303
Towards in through hole, the inner surface contour alignment of the first deep-slotted chip breaker 333 and through hole, latch 303 does not play position-limiting action now to groove 333, will
The carrying transmission mechanism of flange head 302 is inserted in fixed seat 301 together, and the spline tooth alignment on actuating sleeve 341 and drive sleeve 351 is matched somebody with somebody
Close.Latch 303 is rotated, by the first deep-slotted chip breaker 333 dorsad the second deep-slotted chip breaker 321, latch 303 coordinates in the second deep-slotted chip breaker 321
Carry out spacing, prevent flange head 302 from coming off.When restraining position is turned to, spacing ball 334 just falls into limiting plate to latch 303
In spherical groove on 332, prevent latch 303 from rotating.When disassembly is desired, bracing wire is pulled, actuating sleeve 341 and drive sleeve is made in advance
351 depart from, and disconnect and driving.Latch 303 is rotated, the first deep-slotted chip breaker 333 and the second deep-slotted chip breaker 321 is overlapped, flange head 302 departs from
Latch 303 is spacing.
Above-described is only embodiments of the invention, and the general knowledge such as known concrete technical scheme was not made herein in scheme
Many descriptions.It should be pointed out that for a person skilled in the art, on the premise of technical solution of the present invention is not departed from, may be used also
To make some improvement, these should also be considered as protection scope of the present invention, these effects implemented all without the influence present invention
And practical applicability.This application claims protection domain should be defined by the content of its claim, it is specific in specification
Implementation method etc. records the content that can be used for explaining claim.
