Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0036] Example 1, such as Figure 1-4 As shown, this utility model provides a small drilling tool for the renovation of historical buildings, including: a housing 1, which houses a drive motor 101 and has a drill rod 102 connected to its front end; the output end of the drive motor 101 has an installation structure, including a fixed mounting plate 1011 and a threaded mounting part 1012 thereon; the drill rod 102 is detachably connected to the threaded mounting part 1012 through a mounting sleeve 103, and the mounting sleeve 103 has grooves 1031 on both sides for limiting and preventing loosening; a plurality of positioning holes 1021 are provided at one end of the drill rod 102 for adjusting the working angle of the drill bit or limiting the depth, which is suitable for precise drilling operations on traditional materials such as bricks, stones, and wood during the renovation of historical buildings.

[0037] In this embodiment, the drill rod 102 is embedded inside the hollow sleeve 1013. When the drill rod 102 contacts the inclined surface of the positioning pin 1015, the two ends of the spring 1014 are respectively connected to the surfaces of the hollow sleeve 1013 and the positioning pin 1015 to provide a reset for the positioning pin 1015. This facilitates the positioning pin 1015 being embedded in the positioning hole 1021. By embedding the positioning pin 1015 in different positions, drilling work at different depths in historical buildings can be satisfied, and the operation is simple.

[0038] In Example 2, the output end of the drive motor 101 is connected to a mounting plate 1011, which has a threaded mounting part 1012 on one side. The drill rod 102 is quickly locked by driving the positioning pin 1015 through a hollow sleeve 1013 and multiple springs 1014. One end surface of the drill rod 102 has multiple positioning holes 1021 for axial positioning in cooperation with the positioning pin 1015. A mounting sleeve 103 is provided around the drill rod 102, and a sliding groove 1031 is provided symmetrically on the sleeve. A guide rod 1032 and a slider 1033 are provided in the sliding groove 1031. The slider 1033 is driven by a spring 1034 and connected to a protective cover 1035. The protective cover 1035 has a conical structure and is movably fitted around the outer periphery of the mounting sleeve 103 to collect drilling debris and improve operational safety.

[0039] In this embodiment, the mounting sleeve 103 is threaded along the surface of the threaded mounting part 1012, so that the inner wall of the hollow sleeve 1013 is connected to the outer surface of the positioning pin 1015 for auxiliary positioning. The two ends of the spring 1034 are respectively connected to the surfaces of the slide groove 1031 and the slider 1033, which facilitates the reset of the protective cover 1035 on the surface of the slider 1033. Therefore, when the drive motor 101 inside the housing 1 is working, the mounting plate 1011 drives the drill rod 102 to rotate, and the protective cover 1035 is in contact with the surface of the historical building in a vertically upward direction. It can move as the drilling depth is increased, thereby preventing debris from flying and affecting its normal use. When the work is completed, it can be disassembled and cleaned.

[0040] Working principle: Before use, the drill rod 102 is embedded inside the hollow sleeve 1013. When the drill rod 102 contacts the inclined surface of the locating pin 1015, the two ends of the spring 1014 are respectively connected to the surfaces of the hollow sleeve 1013 and the locating pin 1015, providing a reset for the locating pin 1015. This facilitates the locating pin 1015 being embedded in the locating hole 1021. By embedding the locating pin 1015 in different positions, drilling work at different depths in historical buildings can be satisfied, and the operation is simple. In addition, the mounting sleeve 103 is threaded along the surface of the threaded mounting part 1012, so that the hollow sleeve 1012... The inner wall of 013 is connected to the outer surface of the positioning pin 1015 for auxiliary positioning. The two ends of the spring 1034 are respectively connected to the surfaces of the slide groove 1031 and the slider 1033, which facilitates the reset of the protective cover 1035 on the surface of the slider 1033. Therefore, when the drive motor 101 inside the housing 1 is working, the drill rod 102 is rotated by means of the mounting plate 1011 and, together with the protective cover 1035, it is in contact with the surface of the historical building in a vertically upward direction. It can move as the drilling depth is increased, thereby preventing debris from flying and affecting its normal use. When the work is completed, it can be disassembled and cleaned.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
