[0033] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 , the present application provides a steering device, including a steering rod 10 and a handle assembly 20 mounted on the upper part of the steering rod 10. The handle assembly 20 includes a fixing member 201 and two handle rods 202 symmetrically mounted at both ends of the fixing member 201. The two handle rods 202 are respectively rotatably connected to both ends of the fixing member 201. The fixing member 201 adopts a hollow tubular structure. The upper part of the steering rod 10 is fixedly connected to the middle part of the fixing member 201, and the steering rod 10 is internally communicated with the fixing member 201. A telescopic motor 101 is provided inside the steering rod 10. A telescopic motor refers to a driving device with a telescopable telescopic end, such as a telescopic electromagnet, a pen-type push rod motor, etc. The telescopic end of the telescopic motor 101 extends into the fixing member 201 and is connected to the two handle rods 202 through two connecting rods 102 respectively. One end of each of the two connecting rods 102 is rotatably connected to the two handle rods 202 respectively, and the other end is rotatably connected to the telescopic end of the telescopic motor 101. When the telescopic end of the telescopic motor 101 retracts, the two handle rods 202 are pulled to rotate downward relative to the fixing member 201 through the connecting rods 102, realizing the electric folding of the handle rods 202. When the telescopic end of the telescopic motor 101 extends, the two handle rods 202 are pushed to rotate upward relative to the fixing member 201 through the connecting rods 102, realizing the electric unfolding of the handle rods 202.

[0034] Referring to Figures 5 to 7, Further, a rotating connecting member 203 is provided at the end of the handle rod 202 close to the fixing member 201. The rotating connecting member 203 is in the shape of a long handle and protrudes outward from the handle rod 202. The fixing member 201 is provided with a rotating connecting block 204 adapted to the rotating connecting member 203. The rotating connecting member 203 and the rotating connecting block 204 are both provided with corresponding shaft holes 205. When the handle rod 202 is connected to the fixing member 201, the rotating connecting member 203 is inserted into the fixing member 201, and the rotating connection between the rotating connecting member 203 and the rotating connecting block 204 is realized by inserting a pin shaft 206 into the shaft hole 205. A rotating groove 207 is formed inside the rotating connecting member 203. Shaft holes 205 are provided on the side walls of the rotating groove 207 and at both ends of the connecting rod 102. The end of the connecting rod 102 close to the handle rod 202 is inserted into the rotating groove 207, and the rotating connection between the connecting rod 102 and the handle rod 202 is realized by inserting a pin shaft 206 into the shaft hole 205.
