After the plastic bolt 300 adopts the above-mentioned assembly structure, the nut end and the nut of the plastic bolt 300 are respectively disposed on the outer surface of the reflection plate 100 and the outer surface of the signal receiving plate 200.

When it is necessary to lock the plastic bolt 300, it is necessary to first clamp the nut with one wrench and then turn the screw of the plastic bolt 300 with a screwdriver or another wrench, which can accomplish the locking of the nut. In the process of locking the plastic bolt 300, the assembling tool (wrench and screwdriver) is held by the left hand and the right hand, and the tool held by the left hand and the right hand is required to be accurately acted on the plastic bolt 300, and the tool acting forces on the left hand and the right hand are required to be stably coordinated (the acting forces are not stably coordinated, which easily causes the shift of the video transmission antenna and affects the locking process of the plastic bolt 300), so the operation of locking the plastic bolt 300 is very complicated, which greatly affects the convenience and efficiency of the assembly of the video transmission antenna.
Therefore, it is necessary to redesign the structure of the video transmission antenna.
