For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As shown in the accompanying drawings, the utility model includes a vehicle head traction assembly and a wheelchair connection assembly that can be quickly connected and disassembled. The vehicle head traction assembly includes a connecting sleeve 5, a vehicle head support frame 6 and a vehicle head traction rod 7. The vehicle head support frame 6 and the vehicle head traction rod 7 are respectively adjustable and mounted on the connecting sleeve 5;

[0021] The connecting sleeve 5 is movably connected to the frame of the tractor 1 , that is, when the frame rotates, the connecting sleeve 5 is relatively fixed. When the tractor 1 is not connected to the wheelchair 2 , the front support frame 6 can support the tractor 1 .

[0022] The wheelchair connection assembly includes a cross beam 15 and a connecting rod 16, one end of the connecting rod 16 is fixedly connected to the middle of the cross beam 15, and the other end of the connecting rod 16 is respectively provided with a fixed hook 17, a movable hook 18 and a locking hook 19 from front to back, and the opening of the fixed hook 17 is provided with a limiting locking rod 20 for limiting the bottom of the front traction rod 7, and the front traction rod 7 is provided with a pair of positioning shafts 21 respectively matched with the fixed hook 17 and the movable hook 18, and the two ends of the cross beam 15 are respectively provided with fixed pipe clamps 22 connected to the wheelchair frame.

[0023] One end of the connecting rod 16 is welded to the crossbeam 15, and the crossbeam 15 is fixed to the wheelchair frame of the wheelchair 2 by a fixed pipe clamp 22. When the tractor 1 is installed, the front traction rod 7 is inserted under the connecting rod 16, and the two positioning shafts 21 are respectively aligned to the corresponding fixed hooks 17 and movable hooks 18. In this case, there are two fixed hooks 17, movable hooks 18 and locking hooks 19, which are symmetrically located on both sides of the connecting rod 16, and the hooks are located at the bottom. The corresponding positioning shafts 21 also extend to both sides of the front traction rod 7 respectively, which are used to cooperate with the corresponding hooks. The locking hook 19 is located on the outside of the movable hook 18, that is, the positioning shaft 21 located at the front end enters the locking hook 19 and the movable hook 18 at the same time. The movable hook 18 and the locking hook 19 have a pulling force in opposite directions under the action of the spring, which is used to push the entered positioning shaft 21 upward so that the front traction rod 7 can be tightly attached to the connecting rod 16. After the connection is completed, the limit locking rod 20 is inserted to limit the bottom of the front traction rod 7, and the whole front traction rod assembly is completed. Conversely, when disassembling, just pull out the limit locking rod 20, pull the locking hook 19 forward, and then push the front traction rod 7 forward to quickly pull it out from the traction seat 8.

[0024] Furthermore, a connecting seat 9 is provided on the connecting sleeve 5, and one end of the front support frame 6 and the front traction rod 7 are respectively hinged on the connecting seat 9 through a rotating shaft. The front support frame 6 and the front traction rod 7 are both provided with pin shaft mounting holes, and the connecting seat 9 is provided with a group of adjustment positioning holes that match the pin shaft mounting holes of the front support frame 6 and the front traction rod 7 respectively.

[0025] That is, the front support frame 6 and the front traction rod 7 can both be adjusted in angle on the connecting seat 9. After the front traction rod 7 is connected to the connecting rod 16, the frame is pushed forward, adjusted to a suitable angle, and then fixed by the pin. After the handle 4 is pushed forward, the front support frame 6 will maintain a certain distance from the ground. The distance between the front support frame 6 and the ground should be maintained at not less than 100mm to avoid the front support frame 6 from scratching the ground during use.

[0026] Furthermore, the front support frame 6 is assembled by a fixed joint 10 and a telescopic joint 11. The telescopic joint 11 is movably inserted in the fixed joint 10. A limiting screw is provided on the fixed joint 10. A group of locking holes matching the limiting screw is provided on the telescopic joint 11. A transverse support rod 12 is provided at one end of the bottom of the telescopic joint 11. Anti-slip rubber sleeves are provided at both ends of the transverse support rod 12.

[0027] That is, the front support frame 6 is a telescopic rod structure, which can be adjusted in length. The transverse support rod 12 and the frame form a three-point support structure, so that the tractor can be parked stably, and the anti-skid rubber sleeve can effectively prevent the tractor from sliding and tipping over after parking.

[0028] Furthermore, the movable hook head 18 and the locking hook head 19 are both rotatably mounted on the connecting rod 16 via a pin shaft, and the top ends of the movable hook head 18 and the locking hook head 19 are tightened by a spring.

[0029] Preferably, the cross beam 15 is a hollow tube, a transverse adjustment rod 24 is provided inside the cross beam 15 , the transverse adjustment rod 24 is movably inserted into the cross beam 15 , locking screws are provided in the middle and both ends of the cross beam 15 , and the fixed pipe clamp 22 is detachably mounted on the transverse adjustment rod 24 .
