A positioning block 24 is fixedly connected to the side of the positioning frame 22. A positioning pin 25 is inserted into the positioning block 24. A leveling seat 3 flush with the lower side of the positioning frame 22 is fixedly connected to the side of the positioning frame 22. The leveling seat 3 is threadedly connected with a lifting rod 4.

[0028] Adopting the technical solution of this embodiment, the drilling rig device 1 is used for drilling holes in the rock and soil, the auxiliary positioning mechanism 2 is used to make the drill bit 11 of the drilling rig device 1 vertical, the spirit level 222 is used to observe whether the positioning frame 22 is placed horizontally, the positioning ring 23 is used for making a preliminary reference for the drilling position, and then facilitating the adjustment of the position of the drill bit 11. The positioning block 24 is used to connect with the positioning pin 25, and the leveling seat 3 is used to connect the lifting rod 4. When working on flat ground, the lifting rod 4 is located above the positioning frame 22. When the working ground is uneven, by rotating the lifting rod 4 at the concave point downward, the positioning frame 22 can be kept horizontal. After leveling the positioning frame 22, the positioning pin 25 is drilled into the soil layer to prevent the position of the positioning frame 22 from shifting during the drilling process of the drill bit 11.

[0029] Referring to Figure 1 : The positioning blocks 24 are located at the front and rear edges of the positioning frame 22, and two are symmetrically arranged on the front and rear sides.

In this embodiment, when the working frame is kept horizontal by adjusting the height of the lifting rod 4, and then the positioning pin 25 is inserted into the rock, the positioning pin 25 is driven deep into the ground by rotating the rotating cap 251 to prevent the positioning frame 22 from moving. A tool matching the rotating groove is matched with the rotating groove to drive the rotating cap 251 to rotate.

[0031] Referring to Figure 2: Two leveling seats 3 are provided on both the left and right sides of the positioning frame 22, and the two leveling seats 3 are symmetrically arranged on the left and right sides. In this embodiment, the leveling seat 3 is used to install the positioning pin 25.

A rotating ring 41 is fixedly connected to the upper part of the lifting rod 4, and a support plate 42 is fixedly connected to the lower side of the lifting rod 4 on the leveling seat 3. In this embodiment, the working height of the lifting rod 4 is adjusted by rotating the rotating ring 41, and the support plate 42 is used to increase the support surface at the lower end of the lifting rod 4.

[0033] Refer to Figure 1 : A connecting rod 221 is fixedly connected between the positioning ring 23 and the positioning frame 22.

[0034] Refer to Figures 1-2 : The connecting piece 21 is located at the four corners of the drilling rig device 1 and the positioning frame 22, and the cross-section of the connecting piece 21 is right-angled. In this embodiment, the connecting piece 21 is located at the four corners of the drilling rig device 1, which is convenient for observing the position of the drill bit 11.
