[0002] A hair dryer is a household appliance, mainly used to dry wet hair or clothes. It can also be used to blow away dust or dry paintings. It consists of a group of heating wires and a small fan with high speed. When powered on, the heating wires will generate heat, and the wind blown out by the fan will pass through the heating wires and become hot air. If only the small fan is rotating and the heating wire is not hot, then what is blown out is just wind but not heat. The wind blown out by the hair dryer is dry wind. If it is used for too long, it will easily cause water loss and cause heat damage.

[0035] Furthermore, the outer end of the bottom of the rack plate 11 is slidably connected to the bottom of the inner wall of the receiving box 7 .

[0036] During operation, after pressing the two pressing blocks 8, the first spring 14 is squeezed and contracted to generate elastic force, which can drive the gear 10 to rotate through the tooth groove 9. During the rotation of the gear 10, the two rack plates 11 can be driven to move away from each other. After the assembled shell 2 is spliced ​​with the main shell 1, the assembled shell 2 drives the mounting block 6 to extend between the two accommodating boxes 7, so that the two fixing ports 12 move to between the two rack plates 11. After the staff releases the pressing block 8, the elastic force of the first spring 14 pushes the two pressing blocks 8 to move away from each other. By utilizing the connection of the gear 10, the two rack plates 11 can be driven to approach each other, so that the inner end of the rack plate 11 is embedded in the interior of the fixing port 12, and then the mounting block 6 is fixed in the inner cavity of the main shell 1, and then the assembly between the assembled shell 2 and the main shell 1 is fixed for use.
