When the user uses the device, the first PVC protective layer 102 is connected to the second PVC protective layer 103 through the first PVC protective layer 102 and the second PVC protective layer 111. The two PVC protective layers 110 are used together to protect the plastic gear body 101. The inorganic coating 103 and the anti-corrosion layer 104 are used to prevent corrosion of the plastic gear body 101. The hydrophobic layer 105 can prevent water from remaining on the surface of the plastic gear body 101 and affecting the normal use of the plastic gear body 101. The high temperature protection layer 106 and the low temperature protection layer 108 are used together to reduce the phenomenon of thermal expansion and contraction caused by the plastic gear body 101 being in a high or low temperature environment for a long time.

The hydrophobic layer 105 can prevent water from remaining on the surface of the plastic gear body 101 and affecting the normal use of the plastic gear body 101. The high temperature protection layer 106 and the low temperature protection layer 108 are used together to reduce the phenomenon of thermal expansion and contraction caused by the plastic gear body 101 being in a high temperature or low temperature environment for a long time. The use of layer 107 allows for reserved space for thermal expansion and contraction, thereby reducing the possibility of damage to the plastic gear body 101. The use of the fireproof layer 109 reduces the impact of fire on the plastic gear body 101. When the user uses the device, the use of the ventilation groove 201 allows the heat to be dissipated from the friction points between the components of the plastic gear body 101, thereby accelerating the dissipation of temperature.
