The rotation of the threaded rod drives the extrusion groove to move toward the back side, so that it enters the second card slot. When the extrusion groove moves toward the back side, the second extrusion block will first contact the second card slot. At the same time, the plug-in block will continue to move toward the back side, and then the limiting block will be squeezed by the second extrusion block, so that it moves out of the plug-in block and enters the second card slot, completing the connection between the connecting block and the extension rod, ensuring that the electric extension rod can be restarted to push the extension arm to move and rotate.

[0021] The present invention sets an extension rod and rotates a rotating ring. The rotation of the rotating ring drives the telescopic tube to rotate, and then the extension rod is rotated out by rotating the telescopic tube to make it enter the connecting block. When the extension rod moves outward, it will be limited by the fixed ring so that it cannot rotate. The extension rod is rotated out by rotating the rotating ring so that it can be connected to the connecting blocks at different positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Furthermore, the limiting assembly 202 includes a docking ring 202a arranged inside the mounting ring 201b, a slot 202b arranged on the docking ring 202a, an extrusion groove 202c arranged above the docking ring 202a, a clamping rod 202d arranged inside the extrusion groove 202c, a spring 202e arranged on the outside of the clamping rod 202d, and a sliding member 202f arranged above the clamping rod 202d.

[0039] Furthermore, the sliding member 202f includes a sliding groove 202f-1 disposed above the extrusion groove 202c, an extrusion block 202f-2 disposed inside the sliding groove 202f-1, and a limiting plate 202f-3 disposed below the extrusion block 202f-2.

[0040] Operation process: When the staff starts to install the device, they first push the electric telescopic rod 201c into the installation ring 201b. When the electric telescopic rod 201c enters the installation ring 201b, it will drive the docking ring 202a to enter synchronously, and then push the extrusion block 202f-2 to the back, so that the extrusion block 202f-2 slides along the sliding groove 202f-1, and at the same time squeezes the card rod 202d to move downward.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Operation process: rotate the rotating ring 301b, the rotating ring 301b rotates to drive the telescopic tube to rotate, and then the extension rod 301d is rotated out through the rotation of the telescopic tube to make it enter the connecting block 201d. When the extension rod 301d moves outward, it will be limited by the fixed ring 1 301e, so that it cannot rotate. After the extension rod 301d enters the connecting block 201d, the threaded rod 302a is rotated again, and the threaded rod 302a rotates to drive the limit block 302b to move to the back side, so that it enters the second slot 302c When the limit block 302b moves to the back, the extrusion block 303a will first contact the second card slot 302c, and at the same time, the plug-in block 303c will continue to move to the back and squeeze the second spring 302e, and then the limit block 302b will be squeezed by the extrusion block 303a to move it out of the plug-in block 303c and into the second card slot 302c, completing the connection between the connecting block 201d and the extension rod 301d, ensuring that the electric telescopic rod 201c can push the extension arm 102 to move and rotate when it is started.

[0047] Example 3

[0048] Reference Figure 1-7 This embodiment is different from the above embodiments in that the extension rod 301d is movable, so that it can be adjusted according to the position of the connecting block 201d.

[0049] Specifically, a band switch is selected at one end of the electric telescopic rod 301c. After the vehicle body is leveled to meet the requirements, the telescopic arm can be folded and opened. First, confirm that the folding base is located at the tail of the X-axis and close to one end of the electric telescopic rod 301c. Select the arm flip position on the band switch 1, and press it to make the electric telescopic rod 301c start to extend to open or fold the telescopic arm.
