Description

[Technical Field]

[0001] The present invention relates to an electric hand drill, and more particularly to an electric hand drill equipped with an illumination unit. [Background technology]

[0002] Traditionally, a power hand drill is a portable tool that uses an electric motor to rotate a drill bit to drill holes in wood, metal, plastic, and other materials.

[0003] Some such electric hand drills use a level to ensure the accuracy of the drilling direction, as described in Patent Document 1, for example. This allows the user to work while visually checking the vertical or horizontal position of the drill. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 60-004308 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the electric hand drill described in Patent Document 1, the operator must look at the level while working, which poses a risk when drilling a rotating object. Furthermore, in low-light conditions or complex work environments, it is difficult to grasp the exact position of the drill. [Means for solving the problem]

[0006] (1) The electric hand drill of the present invention includes a drill section that extends linearly to drill a hole, a main body section having a motor that rotates the drill section, and an illumination section that irradiates light that includes the tip of the drill section in its light range, and the illumination section irradiates light so that the tip of the drill section is located in the center of the light range in the left-right direction. [Effects of the Invention]

[0007] According to the present invention, the lighting unit allows the worker to easily identify the position and direction of the tip of the drill. This improves work safety, work efficiency, and work accuracy compared to the conventional method using a level. In addition, it makes it possible to clearly identify the position of the drill even in a low-light environment. [Brief explanation of the drawings]

[0008] [Figure 1] 1 is a perspective view showing an electric hand drill according to an embodiment of the present invention; [Figure 2] 1 is a schematic view showing a state in which the electric hand drill according to the first embodiment is used. [Figure 3] 1 is a plan view showing the relationship between light from an irradiation unit of an electric hand drill according to a first embodiment and the tip of the drill. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] An electric hand drill D according to an embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the direction of the tip of the drill unit 1 is referred to as the forward direction, the opposite of the forward direction is referred to as the rearward direction, the extending direction of the grip portion 23 of the main body 2 is referred to as the up-down direction, the left side of the tip of the drill unit 1 as viewed from the main body 2 is referred to as the leftward direction, and the right side of the tip of the drill unit 1 as viewed from the main body 2 is referred to as the rightward direction.

[0010] As shown in Figure 1, the electric hand drill D according to the present invention comprises a drill unit 1, a main body unit 2, and a lighting unit 3. As with a typical electric hand drill D, the drill unit 1 comprises a drill bit for drilling holes in various materials. The drill bit extends in a straight line.

[0011] The main body 2 includes a holder 21 that replaceably holds the drill unit 1 (drill bit), a motor unit 22 that includes an electric motor for rotating the drill bit held in the holder 21, a handle 23 for holding the main body 2 by hand, and a battery unit 24 that supplies power to the electric motor. The handle 23 is shaped to make the electric hand drill D easy to hold and operate.

[0012] The lighting unit 3 is an illumination device consisting of an LED light or the like installed near the tip of the drill unit 1. The lighting unit 3 is designed so that the tip of the drill unit 1 is accurately positioned relative to the work surface, and can brightly illuminate a wide area in a circular pattern. The area onto the work surface onto which light is irradiated is referred to as the light area L. In this embodiment, the lighting unit 3 may also include an adjustment unit that adjusts the direction (angle) of the irradiated light.

[0013] As shown in Fig. 2, the electric hand drill D is held so that the drill unit 1 is perpendicular to the work surface to drill a hole in the work surface. At this time, as shown in Fig. 3, the illumination unit 3 irradiates light so as to form a circular light area L on the work surface.

[0014] As shown in Figure 3, the operator of the electric hand drill D holds the electric hand drill D so that the tip of the drill part 1 is positioned in the center in the left-right direction of the circular light area L, and drills a hole. This allows the drill to drill a hole perpendicular to the work surface without swinging left or right.

[0015] Regarding vertical swing, the electric hand drill D is held so that the tip of the drill unit 1 is positioned at a predetermined vertical position in the light area L, and a hole is drilled. The predetermined vertical position of the light area L can be determined by adjusting the light of the illumination unit 3, for example, so that it is positioned at the upper 1 / 4 of the wide area in the vertical direction. Alternatively, a shadow-like mark can be formed in the light of the illumination unit 3 to indicate the predetermined position. [Industrial Applicability]

[0016] The present invention can be used in an electric hand drill D. [Explanation of symbols]
