The lock hole 11.1 is adapted to the first lock rod 8.2.

[0024] In the embodiment, when the rotating lock rod 8 rotates downward, the end of the first lock rod 8.2 is inserted into the lock hole 11.1 on the rotating disc 11, so that the wheel 18 stops rotating. At this time, the second lock rod 8.3 is separated from the first pipe hole 5.1 and the second pipe hole 6.1 due to the downward rotation of the rotating lock rod 8, so that the longitudinal steel pipe 5 can slide more stably when the wheel 18 is locked.

When the threaded inserting rod 9 rotates to the right, the rack 10 below the threaded inserting rod 9 moves downward together with the threaded inserting rod 9, thereby driving the rotating lock rod 8 to rotate downward through the gear 8.1, when the threaded inserting rod 9 rotates to the left, the rack 10 below the threaded inserting rod 9 moves upward together with the threaded inserting rod 9, thereby driving the rotating lock rod 8 to rotate upward through the gear 8.1, at this time, the rotating lock rod 8 can be controlled to rotate by rotating the threaded inserting rod 9, the operation is convenient, and the bottom end of the threaded inserting rod 9 is conical.

[0026] In the embodiment, when the threaded inserting rod 9 rotates to the right and the first lock rod 8.2 is inserted into the lock hole 11.1 on the rotating disc 11, the wheel 18 is locked and cannot rotate, at this time, the threaded inserting rod 9 is continuously rotated to the right, the bottom of the threaded inserting rod 9 contacts the slope surface of the slope 15, the conical end of the bottom of the threaded inserting rod 9 makes the threaded inserting rod 9 more easily inserted into the ground, when the threaded inserting rod 9 is continuously inserted and rotated to the right, the number of the rack 10 on the third connecting block 9.1 at the bottom of the threaded inserting rod 9 is set, so that after the first lock rod 8.2 is inserted into the lock hole 11.1 on the rotating disc 11, the upper plane of the rack 10 only contacts the gear 8.1 and does not drive the gear 8.1 to rotate, thereby making the first lock rod 8.2 always keep the inserted state, after the threaded inserting rod 9 is inserted into the slope surface of the slope 15, the whole device can be more stably stopped at the original position, at this time, the longitudinal steel pipe 5 can slide in the longitudinal pipe sleeve 6 by being pulled or released by the steel wire rope 14, the included angle between the front frame 1 and the rear frame 2 is adjusted, the electric DTH drill 16 reaches the drilling angle required by the construction, the whole process only needs to be controlled by rotating the threaded inserting rod 9, the operation is more convenient, the working efficiency is improved, and the device is more stable during the adjustment.

[0027] The electric DTH drill is arranged on the base 17, the top of the base 17 is rotatably connected with the cross beam steel pipe of the front frame 1, the bottom of the base 17 is welded above the front wheel shaft 3, and the electric DTH drill 16 can slide on the base 17.

[0028] In the embodiment, after the drilling angle is adjusted, the relative position between the longitudinal steel pipe 5 and the longitudinal pipe sleeve 6 can be locked by rotating the second lock rod 8.3 only by rotating the threaded inserting rod 9, thereby making the electric DTH drill 16 stable at the desired angle, at this time, the electric DTH drill 16 is started to slide on the base 17, the drilling depth is controlled, the controllability is further improved in the whole process, and the operation is more convenient.

[0029] The technical scope of the utility model is not only limited to the content in the above description, and the person skilled in the art can make various deformations and modifications to the above implementation manners without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the range of the utility model.
