The roller 106 is provided, and the lower surface of the roller 106 is in contact with the ground, so that the movable base 107 is convenient to move.

[0036] Please refer to the attached Figure 3-6 The transmission assembly includes a fixed frame 3, which is fixedly connected to the lower surface of the fixed seat 1, and a driving motor 301 is fixedly connected to the outer wall of the fixed frame 3, and a main shaft 302 is rotatably arranged on the inner wall of the fixed frame 3, and the output end of the driving motor 301 is fixedly connected to one end of the main shaft 302, and a first pulley 303 is fixedly sleeved on the outer surface of the main shaft 302, and a second pulley 304 is fixedly sleeved on the outer surface of the rotating shaft 101, and the first pulley 303 and the second pulley 304 are connected by a transmission belt. Through the transmission assembly, when the driving motor 301 is working by turning on the wireless switch 201, its output end drives the main shaft 302 to rotate, thereby driving the first pulley 303 and the first sprocket 401 on the surface of the main shaft 302 to rotate, so that the backrest 103 rotates backward while the support seat 104 rotates upward until it is adjusted to the most comfortable angle for the user, which is more convenient for the user to adjust.

[0037] The transmission assembly also includes a transmission shaft 4, which is rotatably connected to the inner wall of the fixed frame 3.

[0042] When the first sprocket 401 rotates, the second sprocket 402 starts to rotate through the chain 403. When the second sprocket 402 rotates, the transmission shaft 4 and the transmission gear 404 are driven to rotate simultaneously. Since the transmission gear 404 is meshed and connected with the transmission rack 405, the transmission rack 405 is driven to slide on the inner wall of the fixed frame 3 toward the movable base 107, pushing the first connecting ring 406 and the second connecting ring 407, and then pushing the movable base 107 to move toward the support base 104, so that the support base 104 pushes the sliding block 105 to slide in the sliding groove 108, and at the same time, the support base 104 rotates upward;

[0043] Therefore, the backrest 103 rotates backwards while the support seat 104 rotates upwards until it is adjusted to the most comfortable angle for the user, making it more convenient for the user to adjust;

[0044] When the backrest 103 and the support seat 104 need to return to their initial positions, the wireless switch 201 is turned on again to make the drive motor 301 work, and the output end of the drive motor 301 rotates in the reverse direction, and the above-mentioned action is repeated, so that the rotating shaft 101 rotates in the reverse direction and the backrest 103 rotates upward, so that the transmission rack 405 slides in the reverse direction, and then the movable base 107 is pulled through the first connecting ring 406 and the second connecting ring 407 to move away from the support seat 104, so that the support seat 104 rotates downward until it returns to the initial position.

[0058] Therefore, the backrest 103 rotates backwards while the support seat 104 rotates upwards until it is adjusted to the most comfortable angle for the user, making it more convenient for the user to adjust;

[0059] When the backrest 103 and the support seat 104 need to return to the initial position, the wireless switch 201 is turned on again to make the drive motor 301 work, and the output end of the drive motor 301 rotates in the reverse direction, and the above-mentioned action is repeated, so that the rotating shaft 101 rotates in the reverse direction, and the backrest 103 rotates upward, so that the transmission rack 405 slides in the reverse direction, and then the movable base 107 is pulled away from the support seat 104 through the first connecting ring 406 and the second connecting ring 407, so that the support seat 104 rotates downward until it returns to the initial position;

[0060] When the wireless switch 201 is not needed, the handle 208 is pulled upward again, and the above action is repeated to move the protective cover 207 to the top of the placement slot, and then the handle 208 is released to move the protective cover 207 downward and fit into the placement slot. At this time, the protective cover 207 blocks the wireless switch 201 to prevent children or the elderly from accidentally touching it and driving the device to work, causing injuries.
