The ground is circumferentially arranged on the outer wall surface of the cylinder 51.

With the above-mentioned design, as shown in FIG. 5, when a worker uses the positioning and guiding device AA and the hole extractor 50 of the present invention to perform drilling operations, the hole extractor 50 is first to be connected to the set of rods. 52 is installed on an electric rotating tool 61.

Further referring to Fig. 6, then the worker holds the positioning and guiding device AA in one hand, and faces and abuts the front side of the outer bottom plate 11 of the positioning base 10 against a to-be-drilled object 62. The anti-slip layer 111 provided on the front side of the outer bottom plate 11 can assist in fixing the position of the positioning and guiding device AA, and prevent the positioning and guiding device AA from sliding randomly.

Further referring to FIG. 7, then the worker holds the electric rotating tool 61 with the other hand, and inserts the hole extractor 50 assembled on the electric rotating tool 61 axially through the bearing 40 and the inner sleeve 30 in sequence. The bottom plate 31, the liquid storage sponge 20, and the perforation 111 of the outer bottom plate of the positioning base 10 make the cutting portion 53 of the hole taker 50 abut on the object 62 to be drilled, and the cylinder of the hole taker 50 The abutting portion 511 of the body 51 abuts against the inner ring 42 of the bearing 40, and then the electric rotating tool 61 can be activated to drive the hole extractor 50 to rotate, so that the cutting portion 53 is ground on the object 62 to be drilled , Cutting, thereby forming an opening 621.

As shown in Figure 7, during the gradual drilling process of the hole extractor 50, the stop protrusion 54 of the hole extractor 50 will abut against the bearing 40 and push against the bearing 40 as the drilling depth increases. The inner sleeve 30 gradually moves toward the outer bottom plate 11 of the positioning base 10. During this process, the liquid-storing sponge 20 will be squeezed by the inner bottom plate 31 of the inner sleeve 30 and the outer bottom plate 11 of the positioning base 10, and liquid will flow out. The high temperature can also flush the dust generated during the drilling process, so as to maintain the drilling effect of the cutting portion 53.

The positioning and guiding device AA of the present invention can be used to assist in fixing the position of the hole extractor 50, 50A during drilling, and prevent the hole extractor 50 from moving freely on the surface of the hard or smooth object 62 to be drilled. The operation threshold is effectively lowered, so that people with little experience in drilling with the controller 50 can quickly get started, and at the same time, it can also ensure that the hole extractor 50 can accurately drill the extraction hole at the predetermined position.
