[0036] In the disclosed embodiment, the auxiliary tool is composed of a mounting base 2, a lifting rod 3, a support rod 4, a connecting rod 5 and a telescopic rod 6. The lifting rod 3 and the support rod 4 are parallel to each other, and the connecting rod 5 and the telescopic rod 6 are parallel to each other. The lifting rod 3, the support rod 4, the connecting rod 5 and the telescopic rod 6 form a parallelogram frame structure. The mounting base 2 is installed at the top of the frame 1, and the drilling rig is installed at the top of the mounting base 2. By moving the telescopic rod 6 up and down, the position and height of the lifting rod 3 can be adjusted, and then the position and height of the drilling rig can be adjusted to achieve drilling of holes in the roof of the building; the length of the lifting rod can be adjusted by the length adjustment component, and the telescopic rod 6 can also be adjusted.

[0037] The present invention installs a drilling rig on a mounting base, and operates a telescopic rod to raise the drilling rig to drill holes at high places; the length of the lifting rod is adjusted by a length adjustment component, so that it is convenient to drill holes in buildings of different heights; and the working position of the operator is adjusted by adjusting the length of the telescopic rod, so that it is convenient to drill holes in buildings at different locations.

[0038] In one embodiment of the present disclosure, see Figure 2 The length adjustment assembly includes: a cavity 7, which is arranged in the lifting rod 3, and an opening 8 communicating with the cavity 7 is arranged at the top of the lifting rod 3; a first moving rod 9, which is movably arranged in the cavity 7, and the top of the first moving rod 9 extends out of the opening 8 and is connected to the mounting seat 2; a screw rod 10, which is vertically arranged in the cavity 7, and the screw rod 10 is threadedly connected to the first moving rod 9, and the bottom of the screw rod 10 extends out of the lifting rod 3 and is connected to the handle 11, and the screw rod 10 is rotatably connected to the lifting rod 3.

In this way, it is convenient for construction personnel to observe the drilling situation of the drilling rig, improve the drilling construction quality, and reduce the labor intensity of workers.

[0047] In one embodiment of the present disclosure, see Figure 4 and Figure 5, a drilling depth adjustment mechanism is provided on the lifting rod 3, and the drilling depth adjustment mechanism includes: a transmission box 22, which is arranged on the outer wall of one side of the lifting rod 3, and a rotating shaft 23 is rotatably arranged in the transmission box 22, one end of the rotating shaft 23 extends out of the transmission box 22 and is connected to the knob 24, and a gear 25 is provided on the rotating shaft 23; a rack 26 is vertically arranged on one side of the gear 25 and meshes with the gear 25, and both ends of the rack 26 extend out of the transmission box 22, and the rack 26 can reciprocate in the transmission box 22, and a plurality of scale lines are evenly distributed on the surface of the rack 26; a limiting groove body 27 is arranged on the outer wall of one side of the mounting seat 2, and the top of the rack 26 is penetrated The limit groove 27 is connected with the limit ring 28, and the limit ring 28 is located above the mounting seat 2. The bottom end of the limit ring 28 is provided with a dust box 29, and the bottom wall of the dust box 29 is provided with a through hole for accommodating the drill bit of the drilling rig; the limit rod 30 is rotatably arranged in the transmission box 22, one end of the limit rod 30 is in contact with the teeth of the rack 26, and the other end of the limit rod 30 is provided with a pressing head 31, and the pressing head 31 extends out of the transmission box 22 away from the end of the limit rod 30 and can reciprocate on the side wall of the transmission box 22, and one end of the spring 32 is connected to the end of the limit rod 30 away from the pressing head 31, and the other end of the spring 32 is connected to the inner wall of the transmission box 22. In this way, the depth of the drilling rig drilling can be adjusted and limited, the accuracy of the drilling can be improved, and drilling construction at different positions can be convenient.

[0048] Optionally, the dust box 29 is a detachable dust box without a cover, and the dust box 29 is detachably arranged at the bottom end of the limiting ring 28 to facilitate pouring out the collected dust.

[0049] It can be understood that when it is necessary to reduce the drilling depth, the knob 24 is manually rotated to drive the rotating shaft 23 and the gear 25 to rotate, and the gear 25 and the rack 26 are meshed and driven to move the rack 26 upward. The limit groove 27 is slidably connected with the rack 26, and the limit groove 27 limits the displacement of the rack 26 to prevent the rack 26 from turning over. The rack 26 drives the limit ring 28 to move upward, thereby reducing the size of the drill bit and the drilling depth. The limit rod 30 is used to prevent the rack 26 from sliding downward. When the hole depth is reached, the pressing head 31 is manually pressed to disengage the limiting rod 30 from the rack 26, compressing the spring 32, and rotating the knob 24 in the opposite direction to move the rack 26 downward, driving the limiting ring 28 to move downward, thereby increasing the size of the drill bit and increasing the drilling depth. When the position of the limiting ring 28 is adjusted, the pressing head 31 is released to allow the limiting rod 30 to abut against the rack 26 under the action of the spring 32, thereby fixing the rack 26. The dust box 29 moves with the limiting ring 28, and the dust box 29 is used to collect dust generated when the drill bit is drilling.
