[0023] See also Figure 1-5 The utility model provides a technical solution: a shielding cover structure that is easy to position and install, comprising a circuit board 1 and a shielding cover body 2, wherein a fixing seat 11 is symmetrically arranged on the upper end surface of the circuit board 1, an axle seat 12 is arranged on the upper end surface of the fixing seat 11, a semicircular block 13 is arranged on the upper end surface of the axle seat 12, and a limiting ring 14 that can slide up and down is sleeved on the outer wall of the axle seat 12;

[0032] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements.
