Background
In the existing electric power construction, drilling is common construction.
At present, the drilling process usually comprises mechanical drilling and laser drilling, wherein the laser drilling has advantages in the aspects of high-density hole, blind hole, buried hole, micro-hole processing and the like, but the equipment cost is high, the quality of the hole wall is low, and the processed material is limited, so the drilling process still mainly takes mechanical drilling at the present stage, and the mechanical drilling is to drill holes in an electric control cabinet or a place needing to penetrate through the wall by using a drill under the conditions of high rotating speed and falling speed; in the drilling process, dust, impurities and the like are generated due to the high-speed running of the drill bit on the base material,
the traditional process for cleaning the drilled hole comprises the following steps: when drilling, a dust remover is adopted to adsorb dust, sundries and the like of the drill hole, or a fan is used to blow away the dust. When the dust remover is used for removing dust, the drill bit is filled with dust in the drill hole, so that the power is low, the dust is not removed completely, the power is high, and energy is wasted; the dust is blown away by an electric fan, which causes secondary pollution.
In the existing drilling process, the problem that the drilling depth cannot be controlled exists, so that the drilling is shallow, and the drilling needs to be repeated, so that the waste is caused.
The dust removal and depth control in the electric drilling construction seriously affect the physical and mental health of workers and the drilling quality, so that a new drilling device is urgently needed to realize dust removal and accurate drilling and solve the problems of environmental pollution and repeated waste.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., is typically an orientation or positional relationship based on a coordinate system shown in the front view of the device itself or the corresponding sub-component, and that the set of coordinate systems will not rotate with it when other directional views are discussed. In addition, in the case of a rod-like or elongated member, the term "front end" and the term "head" have the same meaning, and the term "rear end" and the term "tail end" and the term "end" have the same meaning. Rather, the foregoing directional terms are used merely to facilitate describing the present application and to simplify the description, and they do not indicate or imply that the apparatus or component being referred to must have a particular orientation or be constructed and operated in a particular orientation without having been stated to the contrary or otherwise specified, and therefore should not be considered limiting of the scope of the present application; further, the terms "inner and outer" with respect to orientation refer to the inner and outer relative to the profile of the respective component itself.

It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", etc. are used to define the components, and are only used to facilitate distinguishing the corresponding components, and if not stated otherwise, the terms have no special meaning, especially, have no special meaning in "main, secondary" or arrangement order, and therefore, should not be construed as limiting the scope of the present application.
