[0006] Furthermore, heat-resistant rubber strips are connected and fixed on two parallel side surfaces of the sheath, and plug-in grooves matching the heat-resistant rubber strips are opened on two opposite inner walls of the rectangular groove. The heat-resistant rubber strips are inserted in the plug-in grooves, and the heat-resistant rubber strips are in contact with the inner walls of the plug-in grooves.

[0007] Furthermore, the middle position of the upper surface of the pressure ring is recessed downward to form an annular groove, a first sealing ring is provided in the annular groove and fits with the pressure ring, a second sealing ring is installed on the inner surface of the pressure ring, and the second sealing ring is sleeved on the lampshade and fits with the outer surface of the lampshade.

[0008] Furthermore, an outer sleeve connected to the lamp holder is installed on the lower surface of the lamp holder, an inner sleeve is inserted in the outer sleeve, the lower end of the inner sleeve is connected and fixed to a chassis, two fixing holes are symmetrically provided on the upper surface of the chassis, a threaded hole is provided on the outer surface of the outer sleeve, and a limit bolt for limiting the relative position of the outer sleeve and the inner sleeve is threadedly connected to the threaded hole.

After the screw passes through the pressure ring, it is connected to the plastic block in a self-tapping manner to complete the assembly of the pressure ring and the ring edge. When the screw head cannot be stuck by common tools due to rust, use an open flame to heat the plastic block so that the plastic block melts due to heat, thereby facilitating the separation of the screw and the plastic block. When the screw head cannot be stuck by common tools, it can be disassembled without damaging the lamp holder and other parts, reducing the difficulty of replacing the bulb after the screw is rusted.

[0013] 2. Insert the sheath into the rectangular groove, and then insert the plastic block into the sheath. When the plastic block is heated and melted, a part of the melted plastic block will adhere to the inner wall of the sheath and be taken out of the rectangular groove together with the sheath, thereby preventing the melted plastic block from remaining on the inner wall of the rectangular groove and affecting the insertion of the new plastic block.
