[0049] ② In the electric drive device 10, the electric drive device 10 includes a mounting seat 11, a motor 12, a transmission rod 13 and a transmission gear set 14; the mounting seat 11 is connected to the first-stage support tube 20; the motor 12 is arranged in the mounting seat 11; the transmission rod 13 is rotatably arranged in the mounting seat 11 and one end is connected to the first-stage drive tube 30; the transmission gear set 14 is arranged in the mounting seat 11 and is respectively connected to the other end of the transmission rod 13 and the output end of the motor 12; the motor 12 can drive the transmission rod 13 to rotate through the transmission gear set 14, so as to drive the drive tube 30 to rotate;

[0050] Specifically, the mounting base 11 is provided with a locking button and an unlocking button, which trigger the switch on the control panel accordingly; taking the conversion of the supporting foot from the retracted state to the extended state as an example for explanation, when the unlocking button is pressed, the control panel sends a command to the motor 12, and the motor 12 drives the transmission rod 13 to rotate after the deceleration of the transmission gear set 14, and the transmission rod 13 drives the first-level driving tube 30, the second-level driving tube 30 and the third-level driving tube 30 to rotate, and then drives the third-level supporting tube 20, the second-level supporting tube 20 and the first-level supporting tube 20 to rotate step by step, thereby driving the third-level locking assembly 40, the second-level locking assembly 40 and the first-level locking assembly 40 to unlock step by step, that is, the restrictions between the third-level supporting tube 20 and the third-level driving tube 30, between the third-level supporting tube 20 and the second-level supporting tube 20, and between the second-level supporting tube 20 and the first-level supporting tube 20 are gradually released;

[0051] When the support legs are fully unfolded, the locking button is pressed, and the control panel sends a command to the motor 12. The motor 12 drives the transmission rod 13 to rotate in the opposite direction after the speed reduction of the transmission gear set 14, and the above process is reversed, thereby limiting the rotation between the support tubes 20 again through the three-level locking assembly 40, thereby maintaining the unfolded state.

[0052] ③It should be noted that the structure of the locking assembly 40, the connection structure between the locking assembly 40 and the driving tube 30, and the connection structure between the locking assembly 40 and the support tube 20 can all adopt existing structures; and the driving tubes 30 and the driving tubes 30 can achieve extension and contraction while achieving synchronous rotation by means of the cooperation of guide grooves and guide blocks, and the guide grooves and guide blocks extend along the length direction of the driving tube 30; they will not be elaborated here, nor shall they be considered as limitations on the present invention.

[0054] Specifically, when the motor 12 fails or there is no external power supply or the battery is dead, the planetary carrier 62 can be rotated to drive the planetary gear 64 to rotate, and then the sun gear 63 can be used to drive the transmission rod 13 to rotate (in one embodiment, the sun gear 63 is installed on the transmission rod 13), and then the drive tube 30 is driven to rotate, and finally manual locking and releasing are achieved, which serves as a safety function.
