[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 5 In the embodiment of the utility model, the handle steering limit mechanism includes a transmission shaft 7, which is characterized in that: the transmission shaft 7 is L-shaped, and external threads 16 are arranged on the outer sides of both ends of the transmission shaft 7. A rotating sleeve 10 is sleeved on one end of the transmission shaft 7, and a second self-locking nut 14 is threadedly connected to the end of the transmission shaft 7 and the corresponding part of the rotating sleeve 10. The second self-locking nut 14 fits with the rotating sleeve 10. A first elastic cylindrical pin 8 is arranged on the transmission shaft 7, and a sleeve 11 is sleeved on the outer side of the other end of the transmission shaft 7. A second gasket 4 is slidably connected to the outer side of the transmission shaft 7 and located on one side of the sleeve 11. A spring 3 is provided on the outside of the transmission shaft 7 and on one side of the second gasket 4, and a first gasket 2 is fixedly installed on one end of the spring 3. A first self-locking nut 1 is threadedly connected to the outside of one end of the transmission shaft 7 through an external thread 16. A through groove 12 for the transmission shaft 7 to pass through is provided on the sleeve 11. Four limiting grooves 13 are provided on the transmission shaft 7 and are located on the outside of the through groove 12 along the circumferential direction. A second elastic cylindrical pin 15 is fixedly installed on the transmission shaft 7 and at a position corresponding to two of the limiting grooves 13. The second elastic cylindrical pin 15 is inserted into the inside of two symmetrical limiting grooves 13.
