Multifunctional handheld drilling machine for construction

Abstract

The invention discloses a multifunctional handheld drilling machine for construction. The multifunctional handheld drilling machine for construction structurally comprises a main hand shank, an auxiliary hand shank, a drilling machine perpendicularity auxiliary device, a drill bit, a snap ring, a machine body and a shoulder rest. One end of the machine body is connected with the shoulder rest, andthe other end of the machine body is provided with the drill bit. Compared with the prior art, the multifunctional handheld drilling machine for construction has the beneficial effects that the drilling machine can drill holes and collect drilling cuttings simultaneously, facilitate cleaning, effectively prevent the drilling cuttings from being splashed anywhere and from injuring an operator; thehand shanks adopt novel structures, the air can be circulated through the space to facilitate quick heat dissipation of the hands of the operator and the hand shanks, and heat of the hand shanks canbe prevented from being transferred to the drilling machine; hollow shank bodies can be cooled through cooling liquid, the hands are further prevented from getting hot and sweating, the hollow shank bodies can maintain cleanliness, antiskid outer shanks can keep dry to prevent bacterium breeding, and the service life of the drilling machine can be prolonged; and the multifunctional handheld drilling machine for construction is additionally provided with a noise reduction and shock attenuation device, has the shock attenuation and noise reduction functions, protects hearing of the operator against damage and prevents noise pollution.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a multifunctional hand-held drilling machine for building. Background technique [0002] Hand drill is a drilling tool powered by AC power supply or DC battery. [0003] Existing drilling machine has the following defects to be improved due to insufficient technology: [0004] (1) When the drilling machine is drilling, the drill cuttings will splash around and cannot be concentrated, which is not conducive to cleaning the drill cuttings, and if the sharp drill cuttings splash on the operator's face, because the facial skin is relatively fragile, Easily scratched by drilling cuttings; [0005] (2) In the hot summer, the operator holds the drilling machine for a long time for drilling operations, and the operation of the drilling machine motor will generate heat, because the normal body temperature of the human body is 36.3-37.2 degrees, and the high temperature in ...

AI Technical Summary

Problems solved by technology

[0004] (1) When the drilling machine is drilling, the drill cuttings will splash around and cannot be concentrated, which is not conducive to cleaning the drill cuttings, and if the sharp drill cuttings splash on the operator's face, because the facial skin is relatively fragile, Easily scratched by drilling cuttings;

[0005] (2) In the hot summer, the operator holds the drilling machine for a long time for drilling operations, and the operation of the drilling machine motor will generate heat, because the normal body temperature of the human body is 36.3-37.2 degrees, and the high temperature in summer will make the hands A certain amount of heat generated by holding the handle is transferred to the body, which is not conducive to the heat dissipation of the motor, which can easily cause the drilling machine to overheat and be damaged. For operators who are prone to sweating, holding their hands on the handle will cause sweat to flow On the handle, the moisture in sweat accounts for the vast majority, more than 99%, and the rest is solid components, mainly sodium chloride, which is easy to nourish bacteria and release sweaty odor, and water will also make the handle wet, which is easy to absorb dust. Makes the handle dirty and difficult to clean;

[0006] (3) The motor generates noise due to high-speed rotation, and the person holds the drilling machine, which makes the distance between the operator and the drilling machine relatively close, so that the noise is easy to cause damage to the operator's tympanic membrane, which affects the operator's hearing. Pollution will also affect the normal life of the surrounding residents
