[0032] The leather drilling device 100 also includes a tool holder 50, which is installed on the end of the pressure plate 24 away from the fixed seat 31, and the cutter 40 passes through the tool holder 50; the sensor 34 is installed on the tool holder 50; when not in use, the tool holder 50 is sleeved on one end of the cutter 40 to prevent the cutter 40 from being accidentally touched.

[0033] In one embodiment, a locator is installed at the bottom of the slider 32, and the locator is used to sense the leather. Optionally, the locator is an infrared sensor, which is a prior art. When the conveyor belt conveys the leather to the slider 32, the locator senses the leather and the conveyor belt stops conveying.

[0034] During use, the conveyor belt conveys the leather to the marking station, and the lifting power element 35 drives the slider 32 to descend until the pen tip of the brush 33 touches the leather, and the telescopic power element 37 then drives the telescopic block 36 to move, thereby driving the pen tip to move and completing the marking; then, the leather continues to be conveyed along the guide strip 28 until the sensor 34 senses the marking on the leather. At this time, the drilling power element 26 drives the lifting plate 23 to descend until the pressure plate 24 touches the leather to prevent the leather from moving; as the lifting plate 23 continues to descend, one end of the connecting rod 27 passes through the lifting plate 23, and at the same time, the lifting plate 23 compresses the elastic part, and the punch 25 presses down the leather, thereby completing the drilling; the waste generated by drilling enters the collection box 29 through the through hole 211 and the through hole; in addition, as the lifting plate 23 descends, the cutter 40 presses down the leather to complete the slitting.

[0035] The leather drilling device 100 of the present invention uses a paintbrush 33 to draw a line on the leather. As the leather is conveyed, when the sensor 34 senses the line, the pressing plate 24 presses down the leather on the supporting plate 21, and the punching needle 25 punches the leather again to complete the punching; at the same time, the cutter 40 presses down and cuts the leather to complete the slitting; the leather drilling device 100 is easy to use and has accurate positioning, and integrates slitting and drilling.
