[0023] When the drilling operation is needed to be carried out on the subway wall, the base 3 is moved to the designated position, the height of the support column 4 is controlled by starting the lifting assembly 6, so that the drilling machine 1 can be moved to the designated height, the reversing assembly 5 is driven by the handle 2 to rotate on the top of the support column 4 through the rotating shaft 5.1, and the strip-shaped plate 5.2 is driven to rotate, when the strip-shaped plate 5.2 rotates, the sliding rod 1.4 can be driven to rotate, when the sliding rod 1.4 rotates, the moving box 1.2 can be driven to rotate, and the drill bit 1.1 is completed to change position, when the drill bit 1.1 changes position, the handle 2 is pressed down, the bottom end of the moving box 1.2 is pushed away from the handle 2, and the sliding rod 1.4 is slid in the strip-shaped groove 5.3, at this time, the drilling machine 1 can be pushed into the wall to complete the drilling operation on the wall.

[0024] The reversing assembly 5 further comprises a toggle lever 5.4, a connecting plate 5.5 and a spring 5.6, the connecting plate 5.5 is provided with two, and is respectively located on both sides of the handle 2, the two connecting plates 5.5 are respectively fixedly installed on the outer walls of both ends of the toggle lever 5.4, and one end of the connecting plate 5.5 away from the toggle lever 5.4 is fixedly installed on the rotating shaft 5.1.

[0025] When the toggle lever 5.4 rotates, the connecting plate 5.5 can be driven to rotate, when the connecting plate 5.5 rotates, the rotating shaft 5.1 can be driven to rotate, and the strip-shaped plate 5.2 can be driven to rotate, and the drilling machine 1 can be driven to change position.

When the pivot 2.3 is at the end of the strip-shaped slot 2.2, the plug rod 2.5 is inserted into the strip-shaped slot 2.2, which can prevent the pivot 2.3 from sliding inside the strip-shaped slot 2.2, and can keep the drilling machine 1 vertical or parallel to the ground, while allowing the knob 2 to stably rotate around the pivot 2.3.

[0036] The two sides of the support column 4 are provided with sliding grooves 4.1, which are arc-shaped. The two ends of the sliding groove 4.1 are connected with strip-shaped slots 4.2, and the two strip-shaped slots 4.2 are perpendicular to each other.
