Liquid crystal displays are widely used in various electronic products, such as mobile phones, computers, and the like. During the production and operation of the liquid crystal display, static charges are accumulated on the surface of the liquid crystal display. In order to discharge static charges, a metal back plate is usually attached to a surface of the lcd to electrically connect the metal back plate and the lcd, so that the static charges accumulated on the lcd can be discharged through the metal back plate.

At present, a conductive film is generally used to electrically connect the metal back plate and the liquid crystal display, and in order to facilitate the conductive film to be attached to the metal back plate and the liquid crystal display, a side edge of the metal back plate is beyond an edge of the liquid crystal display, so a step structure is formed between the side edge of the metal back plate and the edge of the liquid crystal display, the step structure includes a first step surface and a second step surface, wherein the first step surface is located on the metal back plate, the second step surface is located on the liquid crystal display, and one side of the conductive film is adhered to the first step surface of the step structure, and the other side of the conductive film is adhered to the second step surface of the step structure.

In the conductive film attaching process, the conductive film on the first step surface is pre-pressed, the bottom film on the conductive film is torn off, and the conductive film on the second step surface is subjected to pressure maintaining, so that the conductive film is attached.

Therefore, the second mounting hole a2 is connected with any one of the first mounting holes a1 through the first fastener, so that the trachea fixing sleeve 160 is fixed with the bracket 150, the structure is simple, and the installation is convenient. In addition, the second mounting hole a2 is connected to a different first mounting hole a1, so that the position of the outlet of the gas blowing pipe 132 can be adjusted along the longitudinal direction of the base film 300, and the gas blown from the outlet of the gas blowing pipe 132 can accurately act on the bonding portion between the base film 300 and the conductive film 301 of different specifications.

As shown in fig. 5, the upper surface of the tracheal tube fixing sheath 160 is extended in a direction away from the stage 110 to form a connection protrusion, and the second mounting hole a2 is located on a side wall of the connection protrusion.
