Problems solved by technology

[0004] Furthermore, in the past, when drilling, the operator could not accurately control the depth of the drilled hole, so the problem of insufficient or too deep drilling depth often occurred. Therefore, how to control the drilling depth has become another subject to be improved by the present invention.

Embodiment Construction

[0060] The following details are as follows according to the drawings:

[0061] Such as Figure 1-4 As shown, it reveals the structure of the first embodiment of the present invention. The dustproof cover 100 is implemented in conjunction with a hand-held electric drill 200 , which includes: a fitting part 1 , a supporting sleeve 2 , and a dustproof cover 3 .

[0062] The fitting part 1, like a hollow shaft sleeve, can penetrate the fixed part 201 and the rotating part 203 of the electric drill 200, one end of which can be positioned on the fixed part 201 of the electric drill 200, and the other end is connected to the support The sleeve 2 is screwed, and surrounds and isolates the rotating part 203 in front of the fixed part 201 without contact.

[0063] The supporting sleeve 2 is a ring sleeve with a perforated hole in the center, which allows the drill bit 202 of the electric drill 200 to pass through the perforated hole;

[0064] The dustproof cover 3 includes a telescop...

Abstract

The invention provides a dust cover matching a hand-held electric drill. The hand-held electric drill includes a nesting portion, a support sleeve and a dustproof sleeve; the nesting portion is positioned on a fixing portion in the front edge of the electric drill; the support sleeve is connected to the nesting portion and surrounds and isolates a rotation portion of the electric drill; the dustproof sleeve is connected to the other end of the support sleeve, and a drill bit of the electric drill is hidden in the dustproof cover; the dustproof sleeve includes a telescopic sleeve body and a spring; and a limiting device is added, and the limiting device includes a ruler strip parallel to the dustproof sleeve and a limiting block fixed on an outer edge side of the support sleeve. Accordingly, drilling cuttings and dust generated in a drilling process of the electric drill can be collected in the dustproof sleeve, and influence on environment and health due to drilling cutting and dust leakage can be avoided.

Description

technical field [0001] The invention relates to a dustproof cover for a hand-held electric drill, which is a device for collecting drill cuttings and dust during drilling. Background technique [0002] A hand-held electric drill is a small manual machine commonly used in drilling operations such as planks, walls, and ceilings, and its use has been very common. However, during the drilling process, a lot of drill cuttings and dust will be generated flying everywhere and falling to the ground. In addition to causing environmental pollution, they are more likely to be inhaled and affect health, or cause accidental damage to eyes. [0003] In view of this, some advanced people have developed a dust cover for a hand-held electric drill. For example, as shown in the following two patent documents, the dust cover 3 of Patent Document 1 has no spring, so it is not easy to be close to the wall or board surface and cause damage. The dust leaks outside, and the dustproof cover 3 and t...
