Referring to fig. 3 and 5, in the present embodiment, the length of the mounting groove 35 is equal to that of the sliding groove 22, and when the lifting shaft 19 moves to the upper end along the length direction of the sliding groove 22, the connecting shaft 31 at this time also abuts against the top wall of the sliding groove 22; after the reinforcing structure is used, the operator can rotate the output column of the driving motor 23 again, so that the lifting shaft 19 moves downwards along the length direction of the sliding slot 22, the connecting shaft 31 is abutted against the top wall of the mounting slot 35, and then the connecting shaft 31 synchronously moves downwards along the length direction of the sliding slot 42. When the lifting shaft 19 moves downwards along the length direction of the sliding groove 22, the possibility that the connecting shaft 31 is clamped in the tooth groove 41 and cannot fall back downwards is reduced.

The implementation principle of the balance and reinforcement structure of the drilling machine in the embodiment of the application is as follows: in order to keep the body of the drilling machine balanced, the structure is arranged at one end of the body of the drilling machine, which is possible to deviate from the gravity center, at the moment, an operator can rotate an output shaft of the driving motor 23, the output shaft of the driving motor 23 rotates and simultaneously drives the first rotating disc 24, the connecting rod 26 and the second rotating disc 25 to rotate, the relative position of the arc-shaped groove 28 can be changed by the rotation of the second rotating disc 25, so that the lifting shaft 19 moves along the arc length direction of the arc-shaped groove 28, and further the lifting rod 18 is driven to move upwards; in the process that the lifting rod 18 moves upwards, the connecting shaft 31 can also move upwards synchronously, the connecting shaft 31 slides along the inclination direction of the convex teeth 39 at the moment, and the elastic deflector rod 37 elastically deforms until the connecting shaft 31 is aligned with the opening of the tooth groove 41 in the horizontal direction, so that the connecting shaft 31 extends into the tooth groove 41, and the lifting rod 18 is fixed; by rotating the output shaft of the drive motor 23, the lift lever 18 is raised to abut against the drill body, and the lift lever 18 is fixed to the drill body.

After fixed, when the focus of rig body takes place the skew, can make the sliding column 13 receive the power of downstream, and then make the power dispersion of sliding column 13 to dwang 14, under the effect of dwang 14, joint piece 10 has the trend that slides along the incline direction of spigot surface 9, further bracing piece 2 has the trend of outwards opening, and the locking through three bracing piece 2 and mounting 6, the triangular pyramid stability that makes its formation is higher, namely, sliding column 13 receives the decurrent power more big more, make bracing piece 2 support more firm.

When the center of gravity of the drilling machine body shifts to enable the sliding column 13 to move downwards in a small range, the operator can start the driving motor 23 again to enable the lifting rod 18 to move upwards, so that the possibility that the center of gravity is changed due to the shifting of the sliding column 13 is compensated, and the balance and the stability of the drilling machine body are further improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
