[0018] Please refer toFigures 1-4 , the utility model provides a technical solution: including a base 1, a support base 2 is fixed at the rear side of the upper end of the base 1, a mounting plate 3 is slidably connected to the front side of the support base 2, a drilling rig main body 4 is fixed at the upper end of the mounting plate 3, the output end of the drilling rig main body 4 passes through the mounting plate 3 and is fixed with a rotating plate 41, a glass drill bit 5 is installed at the bottom of the rotating plate 41, a docking plate 51 is fixed at the upper end of the glass drill bit 5, a pressure sensor 52 is fixed at the center position of the upper end of the docking plate 51, a group of telescopic grooves 53 are opened at the outer periphery of the upper end of the docking plate 51, a telescopic rod 54 is slidably connected in the telescopic groove 53, the upper end of the telescopic rod 54 is fixed at the bottom of the rotating plate 41, a controller 7 is fixed on the outer side wall of the support base 2, support frames 11 are fixed on the base 1 and on both sides of the support frame 11, anti-slip rubber pads are fixed on the support frames 11, and a groove 24 is opened at the front side of the support base 2 and at the position aligned with the upper end of the support frame 11.

[0019] A lifting groove 21 is opened in the support base 2, a threaded rod 23 is rotatably connected in the lifting groove 21, a lifting block 22 is slidably connected in the lifting groove 21, the lifting block 22 is fixedly connected with the mounting plate 3, the threaded rod 23 passes through the lifting block 22 and is threadedly connected with the lifting block 22, the upper end of the threaded rod 23 extends out of the lifting groove 21 and is installed with a rocker 6, a clutch assembly is arranged between the rocker 6 and the threaded rod 23, the clutch assembly includes a connecting sleeve 61 and a telescopic cylinder 63, the telescopic cylinder 63 is electrically connected with the pressure sensor 52, the connecting sleeve 61 is fixed at the bottom of the rocker 6, the upper end of the threaded rod 23 is rotatably connected in the connecting sleeve 61, the telescopic cylinder 63 is fixed on the side wall of the connecting sleeve 61, a fixed gear 26 is fixed at one end of the threaded rod 23 located in the connecting sleeve 61, an arc-shaped toothed plate 62 is installed on the side wall of the connecting sleeve 61, the arc-shaped toothed plate 62 is meshed with the fixed gear 26, the output end of the telescopic cylinder 63 is fixed on the arc-shaped toothed plate 62, and guide rods 25 are fixed on the front side of the support base 2 and at the positions aligned with the four corners of the mounting plate 3, the guide rods 25 pass through the mounting plate 3 and are slidably connected with the mounting plate 3.

[0020] Working principle: First, install a device to connect to an external power supply. Then, place the glass on the support frame 11 so that the drilling position is aligned with the glass drill bit 5. Next, turn on the drill body 4 and drive the pressing of the mounting plate 3 downward. During this process, the lower end of the glass drill bit 5 abuts against the glass, which will push the docking plate 51 upward and squeeze the pressure sensor 52. The squeezing force is the same as the pressure applied to the glass, thereby achieving the purpose of monitoring the downward pressure and reducing the risk of glass breakage. When driving the mounting plate 3 downward, use the rotation of the rocker 6 to drive the rotation of the connecting sleeve 61. At this time, the arc-shaped toothed plate 62 meshes with the fixed gear 26, so it will drive the threaded rod 23 to rotate synchronously, causing the lifting block 22 to move up and down. Until the pressure reaches a predetermined value, drive the output end of the telescopic cylinder 63 to contract, thereby disconnecting the meshing of the arc-shaped toothed plate 62 and the fixed gear 26. The rotation of the rocker 6 will not drive the threaded rod 23 to rotate synchronously, thereby achieving the drive to stop pressing and further improving the operation safety.
