[0025] Furthermore, the external structure size of the piston rod 5 is designed to correspond to the internal structure size of the guide tube 3. An electric telescopic rod is provided on the top of the connecting block 2. The driving end of the electric telescopic rod extends to the inside of the guide tube 3 and is fixedly connected to the piston rod 5. The piston rod 5 is slidably connected to the guide tube 3 so that the electric telescopic rod can be connected to the guide tube 3. When the electric telescopic rod is in operation, the piston rod 5 can be driven to move. Starting the electric telescopic rod to drive the piston rod 5 to move allows the piston rod 5 to squeeze the gas inside the guide tube 3 and guide the glue inside the guide tube 3. The air pressure opens the second closing piece 16, so that the glue can be discharged from the inside of the guide tube 3, and the amount of glue discharged is controlled. When the glue inside the guide tube 3 is discharged from the inside of the guide tube 3, the air pressure is generated so that the air pressure inside the storage box body 1 and the guide tube 3 are not uniform, so that the glue inside the storage box body 1 can open the first closing piece 7, be introduced into the inside of the guide tube 3, and reset the piston rod 5. The first closing piece 7 and the second closing piece 16 can be reset through two sets of torsion springs to prevent excessive glue inside the guide tube 3. When applying glue, it is prevented that excess glue seeps out and causes waste.

The internal structure size of the sliding groove is designed to correspond to the external structure size of the sliding rod. The movable part 20 is slidingly connected to the sliding rod through the sliding groove. The sliding groove and the sliding rod are slidingly connected so that the movable part 20 can be slidingly connected to the sliding rod.
