This type of tool usually involves tying an electric drill to a telescopic rod, and manually controlling the electric drill to drill holes on the bottom plate of the structure. However, this type of device cannot effectively control the verticality of the hole, and due to the vibration of the electric drill during drilling, the drilling position is often offset, resulting in failure to meet construction requirements.

[0030] The use principle of this new model:

[0031] like Figure 1 , 4 As shown, when in use, according to the height of the structural top plate, adjust the relative position of the sleeve and the top rod, and lock it with the positioning bolt. At this time, place the device on the structural bottom plate, rotate the sleeve, and level the support plate according to the indication of the bubble level. At this time, the drill bit is in a vertical posture, start the electric push rod, the drill bit moves upward and contacts the position where the hole is to be drilled on the top plate, adjust the depth of the screw into the bottom plate, so that the bottom end of the screw also contacts the structural bottom plate. At this time, Figure 4 As shown, the device achieves stable support with the base plate through six points, that is, 3 screws and 3 sleeves jointly support the device to keep the device stable. At the same time, the sleeve moves vertically under the action of the guide sleeve, and the guide positioning of the guide tube and the support column ensures the stable vertical positioning of the drill bit (avoiding the vertical instability caused by the positioning of the guide sleeve alone).

Due to pressure, the bottom end of the screw is further pressed against the base plate, ensuring that the drill bit will not deviate during the drilling process. The electric drill is started to complete the drilling operation.
