Detailed Description

For a better understanding of the technical solutions of the present invention, the following preferred embodiments of the present invention are described in conjunction with the specific examples, but it should be understood that the descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1, the air-conditioning hole core drill guide according to the present embodiment includes:

the locator 10, the locator 10 includes the locating shaft 11, there is a connector 12 making it realize the vertical fixation with the wall on one end of the locating shaft 11;

the guide wheel 20 is connected to the positioning shaft 11 in a rotating mode, the guide wheel 20 and the positioning shaft 11 are arranged coaxially, and the connector 12 is located in a construction circle formed by the outer contour of the guide wheel 20.

Further, the connector 12 is an expansion bolt; the expansion bolt comprises an expansion bolt 121 connected with the positioning shaft 11, an expansion sleeve 122 arranged on the expansion bolt 121, and a pushing nut 123 in threaded connection with the expansion bolt 121.

Preferably, the guide wheel 20 is a nylon guide wheel.

In this embodiment, a drill is used to punch a positioning hole at the center of the pre-drilled air conditioning hole, then the connector 12 (i.e., an expansion bolt) on the positioner 10 is plugged into the positioning hole, the pushing nut 123 is rotated to push the expansion sleeve 122, and under the action of the expansion bolt 121, the connector 12 is fixed to the positioning hole, so that the positioning shaft 11 is vertically fixed to the wall surface, and at this time, the guide wheel 20 is rotatably connected to the positioning shaft 11, thereby completing the installation of the hollow drill guide. Then, a hollow drill for drilling the air conditioning hole is taken out, and the hollow drill is sleeved on the guide wheel 20 to drill the wall surface.

Example 2

Further, the connector 12 is a tip structure (not shown) for hammering the other end of the positioning shaft 11 to be driven into a wall surface.

Preferably, the guide wheel 20 is a nylon guide wheel.

In this embodiment, the other end of the positioning shaft 11 is hammered, and the connector 12 with the pointed end is driven into the wall surface at the center of the pre-drilled air conditioning hole, so that the positioning shaft 11 and the wall surface are vertically fixed, and at this time, the guide wheel 20 is rotatably connected to the positioning shaft 11, and the installation of the hollow drill guide is completed. Then, a hollow drill for drilling the air conditioning hole is taken out, and the hollow drill is sleeved on the guide wheel 20 to drill the wall surface.
