[0024] A through groove 11 is provided on the surface of the pressing plate 6. The through groove 11 is located below the punching drill bit 5 and is arranged to penetrate the pressing plate 6 from top to bottom. The punching drill bit 5 and the inner side of the through groove 11 are adapted to each other. The punching seat 3 is driven down by the telescopic cylinder 4 so that the punching drill bit 5 passes through the through groove 11 to punch holes in the sealing strip. At this time, the spring 9 is in an extruded state. When the telescopic cylinder 4 drives the punching drill bit 5 to be lifted, the spring 9 drives the pressing plate 6 to keep pressing the sealing strip until the punching drill bit 5 is completely separated from the sealing strip, effectively preventing the sealing strip from being lifted up when the punching drill bit 5 is lifted.

[0025] A motor 12 is fixedly installed at the front end of the positioning platform 1, and the output end of the motor 12 extends to the interior of the positioning platform 1 and is fixedly installed with a bidirectional lead screw 13.
