Then, the clamping blocks 203 are moved to the opposite side until the outer surface of the clamping blocks 203 is in close contact with the inner wall of the clamping groove 202, so as to fix the monitor 1 on the fixing base 201.

[0042] refer to Figure 3 As shown, a rebound component 4 is disposed inside the clamping block 203, and two rebound components 4 are provided. The two rebound components 4 include:

[0045] The above scheme is adopted: when the clamping block 203 moves to the opposite side, the clamping block 203 moves inward along the outer surface of the sliding rod 401, squeezing the telescopic spring 402 during movement, and the telescopic spring 402 generates elastic force. When the clamping block 203 enters the clamping groove 202, the telescopic spring 402 releases the elastic force, pushing the clamping block 203 to move to the opposite side.

When the right gear 701 rotates, it engages with the left gear 701, so that the left gear 701 rotates clockwise. The rotation of the two gears 701 drives the travel groove 6 on the surface to rotate together.

[0056] refer to Figure 2 As shown, the drive assembly 8 includes:
