[0012] (1) In this solution, when installing different types of monitoring components, the support component can directly place the bases of different types of monitoring components on the top of the support seat to first contact with multiple groups of suction cups. As the monitoring components are squeezed, the suction cups can be adsorbed into the circular grooves and the bottom of the monitoring components can be in contact with the surface of the support seat. At this time, the control screw shaft can be turned by turning the head to make the piston inside the air pipe move downward to draw pressure, so that the suction cups and the connecting air holes can adsorb and fix the bottom of the monitoring components to ensure the stability of the monitoring components. In this way, the top of the support component can quickly connect and install different types of monitoring components through the support seat, thereby improving the practical effect of the support component.

[0013] (2) After the bottom of the monitoring component is connected to the support component through the support top seat, the bottom of the support component can be placed and supported on the ground through the support base, and the feet at the bottom of the support base can increase the support stability between the support base and the bottom surface. The bottom of the support component can be rotated and adjusted inside the spherical groove by the spherical clamp, and the support component can be adjusted to a horizontal state in conjunction with the horizontal component. At this time, the spherical clamp can be squeezed and fixed by adjusting the fixing screw shaft to ensure the adjustment stability of the support component, thereby achieving the effect of convenient horizontal adjustment according to different installation environments.

[0014] (3) The support assembly is composed of a storage tube and an adjustable screw shaft that are connected and telescopically matched. When the support assembly is used, the adjustable screw shaft can be rotated to allow the adjustable screw shaft to rotate and extend from the inside of the storage tube. After use, the adjustable screw shaft can be rotated and stored in the storage tube in the same way, thereby reducing the overall length of the support assembly, thereby achieving the effect of convenient storage and carrying.
