[0002] In the field of construction engineering, secondary component drilling and rebar installation are frequently required. The traditional method involves workers erecting a scaffold, and after the scaffold passes inspection, workers stand on it and use a hand-held electric drill to drill. Working on a scaffold is far less stable than working on the ground, posing safety risks. Furthermore, traditional drilling methods, requiring hand-held drills, are time-consuming and labor-intensive, while existing auxiliary drilling tools are complex in structure, costly to manufacture, and difficult to process. Therefore, further research is needed to design an efficient and convenient simplified tooling for auxiliary drilling. Utility Model Content

The adjustment structure is provided with a fastening bolt. The lower end of the support structure is fitted onto the adjustment structure. The lower end of the support structure has a through threaded hole. The fastening bolt passes through the threaded hole at the lower end of the support structure and is tightened onto the adjustment structure.

[0005] Preferably, the support structure includes an upper adjusting rod and a support rod, the support rod being arranged perpendicular to the upper adjusting rod, and the bottom of the support rod being welded to the upper end of the adjusting rod.

[0006] Preferably, the upper adjusting rod is a hollow square steel or round tube, and the number of threaded holes penetrating the lower end of the adjusting rod is greater than one.

[0007] Preferably, the adjustment structure includes a lower adjustment rod and a pedal, the pedal being welded to the side of the adjustment rod, and the bottom of the pedal being flush with the bottom of the adjustment rod.

[0008] Preferably, the lower adjusting rod is a hollow square steel or round tube, and the shape and size of the lower adjusting rod match those of the upper adjusting rod.

[0009] Preferably, the threaded hole at the lower end of the adjusting rod is opened at an angle relative to the length direction of the adjusting rod, and the fastening bolt is tightened in the threaded hole, with the angle between the length direction of the fastening bolt and the length direction of the adjusting rod being less than 90 degrees.

[0010] The beneficial technical effects of this utility model are: (1) The raw materials are easy to obtain, the structure is simple, it is easy to manufacture, and the manufacturing cost is low. (2) It is easy to operate, and can be used after a simple briefing for the staff, without maintenance costs. (3) The working length can be easily and quickly adjusted for different heights, which can save time and complete the drilling work quickly and efficiently. Attached Figure Description

[0014] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1

[0015] like Figure 1 and Figure 2 As shown, the simple tooling for auxiliary drilling includes a support structure and an adjustment structure. The support structure includes an upper adjusting rod and a support rod. The support rod is set perpendicular to the upper adjusting rod, and its bottom is welded to the upper end of the adjusting rod. The support structure is mainly used to install and fix the electric drill. The bottom of the electric drill is pressed against the support rod, and the back of the electric drill is pressed against the upper adjusting rod. The electric drill is then installed and fixed to the support structure using bolts or clamping tools. The electric drill is not shown in the figure.

[0016] The adjustment structure includes a lower adjusting rod, a pedal, and fastening bolts. The pedal is welded to the side of the bottom of the adjusting rod, and the bottom of the pedal is flush with the bottom of the adjusting rod. Both the lower and upper adjusting rods are hollow square steel or round tubes, and the shape and size of the lower adjusting rod match that of the upper adjusting rod. In this embodiment, both the lower and upper adjusting rods are hollow square steel, and the lower end of the upper adjusting rod is fitted onto the lower adjusting rod.

[0017] In this embodiment, the lower end of the upper adjusting rod has two through threaded holes. The fastening bolt passes through these threaded holes and is tightened within them. This causes the fastening bolt to press against the surface of the lower adjusting rod, preventing the upper adjusting rod and the electric drill from moving downwards. Since the electric drill generates a downward impact force on the support rod and the upper adjusting rod during drilling, it is difficult to prevent the upper adjusting rod from moving downwards simply by tightening the fastening bolt perpendicularly to the surface of the lower adjusting rod. Therefore, in this embodiment, the threaded holes at the lower end of the adjusting rod are angled downwards relative to the length direction of the adjusting rod. The angle between the length direction of the fastening bolt and the length direction of the adjusting rod is less than 90 degrees, significantly increasing the resistance to the upper adjusting rod and effectively preventing it from moving downwards.

[0018] The specific operation of this embodiment is as follows: First, fix the bottom and back of the electric drill to the support rod and the upper adjustment rod respectively. Place the pedal on the ground and step on it. Then loosen the two fastening bolts, start the electric drill, and then raise the upper adjustment rod by hand until the electric drill reaches the drilling height and position. Then tighten the two fastening bolts, step on the pedal, and hold the upper adjustment rod firmly until the drilling is completed.

[0019] Obviously, any improvements or modifications made without departing from the principles described in this utility model should be considered within the scope of protection of this utility model.
