Principle of work of the present utility model is: when locking state, described drive-connecting shaft is plugged in the endoporus of attaching parts, the connecting bore of drive-connecting shaft is relative with the through hole of attaching parts, described elastic component struts and makes the latch plug-in card to be located in the through hole of attaching parts, drive-connecting shaft is fixed with attaching parts be connected, thus the normal use of assurance stretcher; When needs are dismantled, can manually make elastic component to the compression of axle core, elastic component shrinks and makes latch break away from the through hole of attaching parts, and drive-connecting shaft can be extracted from the attaching parts endoporus, thereby has realized the dismounting of stretcher.Stretcher after extracting can also oppositely insert on the drive-connecting shaft, so that reduce the car load width, conveniently moves or deposits.
Because the employing of technique scheme compared with prior art, the utlity model has following advantage:
1. the utility model is under the mechanical strength that keeps drive-connecting shaft, drive-connecting shaft is transformed, be provided with the attaching parts of cooperation again, thereby realized the disassembled and assembled freely of stretcher, simple in structure, easy to operate, stretcher can oppositely be inserted in this stretcher on the inboard aperture of crank leg after separating the crank leg, thereby dwindled the car volume greatly, be more convenient for moving or depositing.
2. the utility model all is provided with the collar on drive-connecting shaft and attaching parts, and the collar connects by connection lead, thereby the stretcher of pulling down still can be connected on the crank leg, can not lose, and also has certain antitheft effect simultaneously.
3. the utility model is provided with 2～10 circumferential uniform through holes at the top of attaching parts, makes latch be easy to snap in the through hole of attaching parts, thereby has made things convenient for practical operation.
