At this time, the handle on the electric vehicle head drives the driving wire 163 to move, and the driving wire 163 pulls the driving plate 162 to deflect. At this time, the driving plate 162 drives the hook plate 165 to deflect through the connecting rod 164, and at the same time stretches the tension spring 167. At this time, the second lock shaft 23 can be clamped in the position of the clamping groove 166, and the first lock shaft 22 is clamped between the first guide block 17 and the second guide block 18. At this time, the connection between the front connecting member 1 and the rear connecting member A2 is completed. After releasing the handle, the driving wire 163 is relaxed, and at the same time, the tension spring 167 releases its elastic force to drive the hook piece 165 to reset. The hook piece 165 is now in a locked state, locking the second lock shaft 23. At the same time, due to the inclined setting of the first guide block 17 and the second guide block 18, the first lock shaft 22 cannot be moved out at the same time, so that the connection between the front connecting member 1 and the rear connecting member A2 is reliable. Similarly, when the wheelchair and the electric head are disassembled, the driving wire 163 pulls the hook piece 165 to rotate and give way, which facilitates the separation of the second lock shaft 23, thereby completing the disassembly of the electric head from the wheelchair.

[0039] The above specific embodiment is only an optional embodiment of the present invention.
