[0038] The pulling arrangement (201) comprises a drive motor (201a) provided within the third storage plate (104c), a drive belt (201b) provided on the drive motor (201a), a first rotary plate (201c) provided between the first drive shaft (104c-1) and the third drive shaft (104b-1), and a second rotary plate (201d) provided between the second drive shaft (104c-2) and the fourth drive shaft (104b-2), wherein the first rotary plate (201c) is rotatably connected to the first drive shaft (104c-1) and the third drive shaft (104b-1), and the second rotary plate (201d) is rotatably connected to the second drive shaft (104c-2) and the fourth drive shaft (104b-2), wherein the drive belt (201b) is located between the drive motor (201a) and the first Drive shaft (104c-1).

[0039] The number of the first rotary plate 201c and the second rotary plate 201d is two, and two adjacent first rotary plates and the second rotary plate 201d are arranged symmetrically along the center line of the support shell 101. The two ends of the third drive shafts 104b-1 extend from the second rotary plate 104b to be connected to the two ends of the first drive shafts 104c-1 through the first rotary plate 201c, respectively. The two ends of the fourth drive shaft 104b-2 are connected to the two ends of the second drive shaft 104c-2 via the second rotary plate 201d, and the first rotary plate 201c and the second rotary plate 201d serve as important conversion components in the drive chain.

[0050] The limiting member (202e) comprises a first fixing post (202e-1) provided on the transmission gear disc (202d-1), a second fixing post (202e-2) provided on the transmission gear disc (202d-1), and a limiting pick (202e-3) provided on the first fixing post (202e-1).The transmission gear disc (202d-1) further comprises a pawl (202d-1a), a connecting sleeve (202d-1b), a return spring (202d-1c) and an upper block (202d-1d), wherein the pawl (202d-1a) is located on the inner wall of the side plate (202a), wherein the pawl (202d-1a) engages with the transmission gear disc (202d-1), and wherein the connecting sleeve (202d-1b) is located below the pawl (202d-1a), wherein the connecting sleeve (202d-1b) is hollow inside, wherein the return spring (202d-1c) is located inside below the connecting sleeve (202d-1b), and wherein the end portion of the upper block (202d-1d) is provided with the return spring (202d-1c).

[0051] Specifically, the first fixing post 202e-1 and the second fixing post 202e-2 are disposed on a side surface of the transmission gear disc 202d-1, and the rotating shaft 202c-1 is fixedly connected to a limit picker 202e-3 on the periphery of the rotating shaft 202c-1, which mates with the first fixing post 202e-1 and the second fixing post 202e-2. The second tray 104b is rotated to the right side of the third tray 104c while maintaining a horizontal state with the cooperation of the four rotating plates. The rotary shaft 202c-1 rotates clockwise relative to the second storage plate 104b under the cooperation of the second storage plate 104b and the first rotary plate 201c, and the rotary shaft 202c-1 drives the transmission gear disk 202d-1 to rotate counterclockwise by means of the chain, the first gear 202d-2 and the second gear 202d-3.The rotation of the transmission gear disc 202d-1 causes the first mounting post 202e-1 on the transmission gear disc 202d-1 to rotate counterclockwise around the center point. The counterclockwise rotation of the first mounting post 202e-1 presses the limit picker 202e-3, causing the limit picker 202e-3 to rotate clockwise around the first drive shaft. The rotation of the first drive shaft drives the support plate 202c-2 to rotate, keeping the support plate 202c-2 in a vertical state.

[0052] In order to lock the support plate 202c-2 when it is rotated to the two limit states of the first fixing post 202e-1 and the second fixing post 202e-2, a number of locking teeth are evenly arranged on the transmission toothed disk 202d-1, and a locking pawl 202d-1a is integrally formed and connected to the locking teeth on the periphery of the drive shaft on the inner wall of the side plate 202a. Inside the side plate 202a, there is a hollow connecting sleeve 202d-1b fixed at the position corresponding to the locking pawl 202d-1a, a return spring 202d-1c connected to the bottom of the hollow space of the connecting sleeve 202d-1b, and an upper block 202d-1d fixedly provided at the upper end of the return spring 202d-1c. An outer end of the upper block 202d-1d is provided with a pawl 202d-1a having a pointed, raised structure for engagement.When the second support plate 104b is in the correct position of the third support plate 104c, the locking pawl 202d-1a engages with the locking teeth of the transmission pulley 202d-1, the first mounting post 202e-1 engages with the limit pick 202e-3, and the support plate 202c-2 is in a stable vertical state. The rotation angle of the apex of the locking pawl 202d-1a is limited by the connecting sleeve 202d-1b, and the return spring 202d-1c presses the upper block 202d-1d, which can hold the locking pawl 202d-1a at a fixed angle.

[0053] Operation: The third drive shaft 104b-1 drives the transmission gear disc 202d-1 counterclockwise via the transmission chain 202d-4, the first gear 202d-2 and the second gear 202d-3, and the rotation of the transmission gear disc 202d-1 causes the first fixing post 202e-1 on the transmission gear disc 202d-1 to rotate counterclockwise around the center. The counterclockwise rotation of the first fixing post 202e-1 pushes the limit pick 202e-3 so that the limit pick 202e-3 rotates around the rotary shaft 202c-1 and drives the rotary shaft 202c-1 to rotate, and the rotation of the rotary shaft 202c-1 drives the pawl 202d-1a to rotate clockwise around the rotary shaft 202c-1.The rotation of the rotary shaft 202c-1 drives the rotation of the support plate 202c-2, and when the second tray plate 104b is rotated from the left side of the third tray plate 104c to the right side thereof, the support plate 202c-2 is accurately rotated from an inclined state to a vertical state;.

[0054] During the rotational movement of the second tray plate 104b in a horizontal state, the first electrically driven push rod 202b extends to assist the movement of the second tray plate 104b. When the second tray plate 104b reaches the position on the left side of the tray plate, the locking pawl 202d-1a engages with the locking teeth of the transmission gear plate 202d-1, the first fixing post 202e-1 engages with the limit picker 202e-3, and the support rod is in a stable vertical state, and the transport mechanism is in the second mode, in which the transport mechanism can support large loads.At this time, the lifting cylinder raises the lifting plate 103b, the lifting plate 103b drives the first storage plate 104a, the third storage plate 104c rises, the electrically driven telescopic rod 103c-2 extends, the first electrically driven push rod 202b extends to enable the transportation and handling of bulky loads, and the second electrically driven push rod 202c-3 extends to serve as an auxiliary support in handling loads of the large-volume goods.

[0055] The rotation angle of the apex of the pawl 202d-1a is limited by the connecting sleeve 202d-1b, and the return spring 202d-1c presses the upper block 202d-1d, so that the pawl 202d-1a can be held at a fixed angle in the first and second modes.

[0056] When the handling of the large-volume goods is completed, the lifting cylinder, the first electrically driven push rod 202b, the electrically driven telescopic rod 103c-2, and the second electrically driven push rod 202c-3 are retracted. Then, the drive motor 201a is reversed, and the second fixing post 202e-2 pushes the locking pawl 202e-3 counterclockwise, so that the support wheel 202c-4 is finally retracted as a whole.

[0057] The remaining structure is the same as in Embodiment 2.
