When the rotating adjusting gear 3 moves leftwards, the driving side teeth I304 and the driven side teeth I502 are used for meshing transmission, so that the central gear 501 rotates, and the rotation of the central gear 501 is used for driving the transmission adjusting mechanism 6 to rotate around the axis of the adjusting gear 3. The axes of the output shaft of the motor I201, the adjusting gear 3, the central combined gear 5 and the connecting pipe III 606 coincide. When the central gear 501 rotates, the gear 601 rotates around the axis of the connecting pipe III 606, and as a result, the transmission adjusting mechanism 6 rotates around the axis of the connecting pipe III 606 as a whole. The axis of the main shaft 703 coincides with the axis of the connecting pipe III 606, and when the rotating adjusting gear 3 moves rightwards, the driving side teeth II 305 and the driven side teeth II 701 are engaged to drive the whole transmission adjusting assembly 7 to rotate around the axis of the main shaft 703. I.e. the side-to-side movement of the adjusting gear wheel 3, respectively, results in a movement pattern, the purpose of which is to make a high degree of freedom adjustment of the drilling mechanism 8. Further, when the adjusting gear 3 which performs rotation is driven by the dial frame 405 to move rightwards and is in meshed transmission with the driven side gear II 701, the bevel gear II 704 rotates. On the other hand, the incomplete stop plate 406 and the complete stop plate 407 move rightwards, the incomplete stop plate 406 is separated from the incomplete friction surface 702, the complete stop plate 407 is in contact with the complete friction surface 607, a friction force I is generated between the complete stop plate and the complete friction surface 607, the friction force I is used for enabling the connecting pipe III 606 to stop rotating, further the arm body II 608 becomes a machine frame, the bevel gear II 704 is used for driving the bevel gear I610 to rotate, the bevel gear I610 drives the turning extension shaft 801 to rotate around the axis of the shaft II 609, further the drill 803 can be enabled to rotate around the axis of the shaft II 609, and the angle of the drill. When the adjusting gear 3 which rotates is driven by the dial frame 405 to move leftwards and is in meshing transmission with the driven side tooth I502, the incomplete stop plate 406 and the complete stop plate 407 also move leftwards. The incomplete stop plate 406 is used for contacting the incomplete friction surface 702, and a certain friction force II is generated between the incomplete stop plate and the incomplete friction surface 702, the friction force II is used for enabling the helical gear II 704 to bear resistance to rotation, but the resistance does not influence the helical gear I610 to drive the helical gear II 704 to rotate through the power provided by the motor I201. This resistance is used to fix the angle at which the drill 803 drills when the motor i 201 is contracting the brake, without the shaft 703 rotating by the vibration generated when the drill 803 drills the earth.
