AI Technical Summary
Current electric drills can usually only be held with one hand, which leads to unstable grip and affects drilling accuracy. In addition, they lack guiding and auxiliary mechanisms, which can easily result in drilling holes that are too shallow or too deep.
A drilling accuracy is ensured by using an auxiliary handle assembly and a guiding mechanism, including an adjustment hole, a scale rod, a limiting housing, a clearance channel, and a hexagonal nut, which are operated by both hands and adjusted by the scale rod.
It achieves stability for two-handed operation, avoids drilling too shallow or too deep, and improves drilling accuracy and stability.

[0020] Figure 3 is a schematic view of an auxiliary handle structure of an electric drill with auxiliary handle according to an embodiment of the present disclosure. Figure 2 is an enlarged schematic view of the A part in the middle.
[0021] The reference numerals in the drawings are specifically as follows:
[0022] 1, electric drill body;
[0023] 2, auxiliary handle assembly; 21, fixed collar; 22, rubber convex strip; 23, extension handle; 24, anti-skid sleeve;
[0024] 3, guiding auxiliary mechanism; 31, adjusting hole; 32, scale rod; 33, limiting shell; 34, avoiding channel; 35, hexagonal nut; 36, adjusting bolt. DETAILED DESCRIPTION
[0025] For descriptive purposes, the present disclosure can use spatially relative terms, such as "below", "beneath", "lower", "under", "above", "upper", "higher", and "side" (e.g., as in "side wall") to describe the relationship between one component and another component as shown in the drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture, for example, the component described as "below" or "beneath" another component or feature can subsequently be positioned "above" the other component or feature as a result of the device being turned over. Thus, the exemplary term "below" can encompass both an orientation of above and below. Furthermore, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0026] As shown in the drawings, the electric drill with auxiliary handle of the present disclosure can include the following components: electric drill body 1, auxiliary handle assembly 2, guiding auxiliary mechanism 3, etc. Figures 1-3 As shown in the drawings, the electric drill with auxiliary handle of the present disclosure can include the following components: electric drill body 1, auxiliary handle assembly 2, guiding auxiliary mechanism 3, etc.
[0027] Figure 2 As shown, in the present disclosure, the auxiliary handle assembly 2 comprises a fixed collar 21 which is sleeved on the outside of the body 1 of the electric drill, and a plurality of rubber protrusions 22 are bonded on the inner side of the fixed collar 21, and the rubber protrusions 22 are uniformly attached between the inner wall of the fixed collar 21 and the body 1 of the electric drill, and the fixed collar 21 is detachably sleeved on the outside of the body 1 of the electric drill through the friction between the body 1 of the electric drill and the rubber protrusions 22, and an extension handle 23 is fixedly arranged on the outside of the fixed collar 21, and a non-slip sleeve 24 is fixedly sleeved on the outer end of the extension handle 23.
[0028] Thus, in order to facilitate the drilling process, one hand holds the handle of the body 1 of the electric drill, and the other hand holds the non-slip sleeve 24, thereby improving the stability during drilling.
[0029] As shown, Figure 3 In a preferred embodiment, the guiding auxiliary mechanism 3 comprises an adjusting hole 31, a scale rod 32, a limiting shell 33, an avoiding channel 34, a hexagonal nut 35 and an adjusting bolt 36, wherein the adjusting hole 31 is throughly arranged on the extension handle 23, the scale rod 32 is slidingly arranged on the inside of the adjusting hole 31, the limiting shell 33 is fixedly arranged on the side of the extension handle 23, the avoiding channel 34 is opened on the right side of the limiting shell 33, the hexagonal nut 35 is clamped on the inside of the limiting shell 33 and is sleeved on the outside of the adjusting bolt 36, and the adjusting bolt 36 penetrates through the side wall of the limiting shell 33 and the extension handle 23 and extends to the inside of the adjusting hole 31.
[0030] Thus, before drilling, the adjusting bolt 36 is loosened, the end of the drill bit on the body 1 of the electric drill is attached to the wall, then the scale rod 32 is slid to the left end of the scale rod 32 attached to the wall, and finally the scale rod 32 is slid to the right side according to the estimated actual drilling depth, and during the sliding process, the scale marks on the scale rod 32 are referenced, and after the adjustment of the scale rod 32 is completed, the adjusting bolt 36 is tightened to lock the scale rod 32, and when the subsequent drilling operation is performed again, as the hole is continuously drilled, the scale rod 32 continuously approaches the workpiece, and finally stops at the surface of the workpiece to limit the movement of the body 1 of the electric drill and the drill bit, compared with the prior art, the present utility model can perform the drilling operation with both hands, and can avoid the situation of drilling too shallow or too deep, and the actual use effect is better.
[0031] It should be further pointed out that the adjusting hole 31, the limiting shell 33, the avoiding channel 34 and the extension handle 23 are integrally formed.
[0032] Thus, the production difficulty and cost of the auxiliary handle assembly 2 and the guiding auxiliary mechanism 3 are reduced.
[0033] It should also be noted that the content not described in detail in the present specification belongs to the prior art known to those skilled in the art.
[0034] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure.
