[0028] like Figure 8 and Figure 9As shown, the adapter adjustment component 4 includes an adjustment bolt 401 rotatably mounted on the rotating arm 301; an adjustment slider 402 is threadedly connected to the adjustment bolt 401; a gear is rotatably mounted on the adjustment slider 402; the adjustment slider 402 is slidably mounted in a groove on the rotating arm 301; the gear rotatably mounted on the adjustment slider 402 meshes with a synchronous toothed belt 403; the synchronous toothed belt 403 is driven by the drilling gear 306 and the linkage gear 307. Using the adapter adjustment component 4 for drilling power transmission, the adjustment is not affected by the position of the drilling component 3, allowing for rapid adjustment. To ensure the rationality of the structure, each drilling component 3 can achieve drilling power output. At the same time, the structure can be quickly adapted, reducing the cost of batch drilling and ensuring adjustability and flexibility.

[0029] like Figures 6 to 11As shown, the leveling adjustment component 5 includes an adjusting connecting cylinder 501 fixedly sleeved at the bottom of the insertion cylinder 201; a micro switch 502 is fixedly installed on the top of the adjusting connecting cylinder 501; a spherical groove is provided at the bottom of the adjusting connecting cylinder 501; a movable control disk 503 is slidably installed inside the adjusting connecting cylinder 501; a groove is provided at the bottom of the movable control disk 503; a spring is provided on the top of the movable control disk 503, and the spring on the top of the movable control disk 503 is located inside the adjusting connecting cylinder 501; the micro switch 502 is located on the movable control disk 503.

[0031] The working principle of the technical solution provided by this invention is as follows: First, place the gearbox housing on the support platform 104, then tighten the two positioning screws 702 for compression positioning. Slide the telescopic rod 302 to extend and retract, and adjust the angle in conjunction with the rotating arm 301. Rotate the positioning bolts 304 on both sides for positioning, and press the positioning telescopic rod 302 by rotating the positioning bolts 304. Control the drilling machine body 101 to lower the spindle gear 103. At this time, drilling can be performed through the drill bit installed at the bottom of the drill bit connecting column 305. When it is necessary to replace the drilling part 3, the replacement bolt 202 can be rotated directly to release the limiting plug tube 201. At this time, different plug tubes 201 and their matching components can be replaced. Different numbers and specifications of drilling parts 3 can be set on the plug tube 201. Rotate the adjusting bolt 401 to drive the adjusting slider 402 to move. Utilize the movable characteristic of the adjusting slider 402 to drive the gear on the adjusting slider 402 to match the synchronous toothed belt 403. Always keep the synchronous toothed belt 403 in close contact and drive between the drilling gear 306 and the linkage gear 307.

[0032] As the main shaft gear 103 descends, it causes the control detection frame 603 to adhere to the end face of the gearbox housing. As the main shaft gear 103 continues to descend, the tension spring 602 is stretched, and the detection frame 603 also elastically adheres to the end face of the gearbox housing. If the upper end face of the gearbox is tilted, the detection frame 603 will also tilt, causing the ball joint 504 to rotate in the spherical groove at the bottom of the adjusting connecting cylinder 501, which in turn causes the swing rod 505 to swing. The swing rod 505 can then press the moving control disk 503, which in turn can press the micro switch 502, thereby controlling the alarm light 1041 to light up and sound an alarm.
