The invention discloses a power pressing plate structure comprising a pressing plate body. The pressing plate body is formed by two spliced plate bodies. The two plate bodies are both equipped with transverse reflection devices. One end of each reflection device is connected with the pressing plate body. The other end of each reflection device is fixed to a reflection material installing seat. Both sides of the pressing plate body are provided with connection devices. The connection devices and the pressing plate body are integrally connected. One connection device of the pressing plate body is connected with a wire pipe. A transistor is vertically installed in the wire pipe. A conductive plate is installed on the top of the wire pipe and is connected with the transistor through a built-in wire. The power pressing plate structure has good using performance and conductive performance, facilitates wire passing and the installation of reflection materials, achieves tight component connection and good self-protection, effectively reduces hidden dangers such man-made operation faults and adverse judgment, further decreases adverse use risk, and facilitates checking and overhauling.
