[0032] As Figure 3 , 5As shown in FIG. 6, the elastic assembly 12 further comprises a clamping shaft 121 arranged on the mounting plate 102, a first knob 122 arranged at one end of the clamping shaft 121, a second knob 123 arranged at one side of the first spring 120, a first washer 124 arranged at one side of the second knob 123, a second washer 125 arranged at one side of the mounting plate 102, and a limiting piece 126 arranged at one side of the second washer 125. The first knob 122 is used to limit the first spring 120 in cooperation with the limiting block 103, and the second knob 123 is used to limit the first spring 120 in cooperation with the adjusting block 113. The clamping shaft 121 is used to cooperate with the mounting plate 102 to link the elastic assembly 12 with the supporting unit 2. Specifically, the first spring 120 is arranged on the clamping shaft 121 through a spring sleeve 127. One end of the clamping shaft 121 is provided with a first anti-rotation segment, which is used to drive the first knob 122 and the second knob 123 to rotate synchronously.

When the elastic assembly 12 is assembled, first, the clamping shaft 121 is passed through the connecting shaft seat 210 of the supporting member 21, and the round shaft is sleeved into the connecting shaft seat 210. Then, the second washer 125, the limiting piece 126, and the second washer 125 are stacked and sleeved into the clamping shaft 121. Then, the mounting member 10 is sleeved into the clamping shaft 121, and then the first washer 124 is sleeved into the clamping shaft 121. Then, the second knob 123 is sleeved into the clamping shaft 121. Then, the spring sleeve 127 is sleeved into the clamping shaft 121. Then, the first spring 120 is sleeved outside the spring sleeve 127. Then, the first knob 122 is sleeved into the clamping shaft 121. The assembly of the elastic assembly 12 is completed.

The limiting piece 126, the first knob 122, and the second knob 123 are clamped and connected with the first anti-rotation segment of the clamping shaft 121, and cannot rotate relative to each other. One side of the second knob 123 is clamped and connected with the first extending end of the first spring 120. The second extending end of the first spring 120 is in abutting contact with the adjusting block 113. One side of the first knob 122 is clamped and connected with the second extending end of the first spring 120. When the connecting unit 1 and the supporting unit 2 rotate relative to each other clockwise, the first knob 122 compresses the first spring 120 in cooperation with the limiting block 103, so as to generate a torque on the first knob 122 through the rebound reaction force, so as to keep the connecting unit 1 and the supporting unit 2 in force balance. Of course, when the connecting unit 1 and the supporting unit 2 rotate relative to each other counterclockwise, the second knob 123 compresses the first spring 120 in cooperation with the adjusting block 113, so as to generate a torque on the second knob 123 through the rebound reaction force, so as to keep the connecting unit 1 and the supporting unit 2 in force balance. Therefore,The relative rotation angle of the connecting unit 1 and the supporting unit 2 is different, and the compression amount of the first spring 120 also changes, and the elastic force generated by the first spring 120 can always keep the connecting unit 1 and the supporting unit 2 in force balance in the corresponding state (when there is no external force interference).
