[0032] With such a design, when in use, the top plate 2 is first driven down to a suitable height by the lifting electric push rod 3 to lower the height of the PTC electric heater during installation, and then the PTC electric heater is placed on the top plate 2 by hoisting or other means, and then the top plate 2 is raised to the required height by the lifting electric push rod 3, and then the power plate 5 is driven to move by the power electric push rod 4, and the power plate 5 drives the two sliding blocks 7 to move through the two connecting rods 6, and the corresponding clamping parts are driven to move by the sliding blocks 7, and the PTC electric heater is clamped and fixed by the clamping parts.

[0033] It should be noted that the support unit and the connecting frame are fixed by bolts, so during transportation, the two support units and the connecting frame can be disassembled to achieve modular assembly and disassembly, thereby reducing the space occupied during transportation.
