When the second button 31 is pressed to move the sliding plate 32, so that the second stop opening 321 moves away from the stop block 112 to unlock, the shelf 12 can move left and right relative to the outer column 11.

[0041] like Figure 5-6 As shown, in this embodiment, the left and right adjustment component 3 is housed in the shelf 12. The front end of the shelf 12 has an opening to allow the second button 31 to extend, making it convenient for the user to press the second button 31 and then grasp the shelf 12 to move it left and right to adjust its position. The inner walls of both the left and right ends of the shelf 12 are provided with limiting blocks 122. The left and right sidewalls of the second button 31 abut against the limiting blocks 122 to make the structure more stable when the second button 31 slides.

[0042] Optionally, the sliding plate 32 is provided with a mounting groove 323 and a mounting post 324 at its front and rear ends, respectively. One end of the second button 31 is limited in the mounting groove 323 to push the sliding plate 32 to move and unlock. The left and right adjustment component 3 includes a spring 33, which is sleeved on the mounting post 324 to push the sliding plate 32 to reset and lock.

[0043] like Figure 6 As shown, in this embodiment, the shelf 12 is provided with an abutment part 123, and the two ends of the spring 33 abut against the sliding plate 32 and the abutment part 123 respectively. After the user presses the second button 31, the second button 31 pushes the sliding plate 32 to slide backward, and the sliding plate 32 squeezes the spring 33. At this time, the second gear position port 321 moves backward and away from the gear position block 112 along with the sliding plate 32, so that the gear position block 112 is unlocked. Then the user pushes the shelf 12 to move left and right to adjust the gear. When the second button 31 is released, the spring 33 drives the sliding plate 32 to rebound, so that the second gear position port 321 relocks the gear position block 112 to complete the left and right adjustment process.

[0044] like Figure 6 As shown, optionally, the sliding plate 32 is provided with a plurality of third protrusions 322, the protrusion direction of the third protrusions 322 is parallel to the pressing direction of the second button 31, and the second gear opening 321 is the gap between the left and right adjacent third protrusions 322.

[0045] Optionally, the upper end of the outer column 11 is provided with a positioning bolt 113, and the shelf 12 is provided with a limiting hole 121. The outer column 11 and the shelf 12 are connected by the positioning bolt 113, and the positioning bolt 113 and the limiting hole 121 are slidably connected left and right.
