Embodiment Construction

[0031] As shown, there is shown a dust extraction device 100 of the present invention attached to a hand-held power tool such as a hand drill 10 for removing the work of the hand drill 10 when used in conjunction with an external household vacuum cleaner 30 dust and / or debris from the The hand drill 10 has a plastic body 11 including an integral pistol handle 12 at its rear end and a front end 13 from which a chuck 14 projects forwardly for holding a drill bit 15 . The hand drill 10 is combined with a separate plastic handle 20 that includes a metal ring 21 that snaps around the front end 13 of the hand drill 10 so that the hand drill 10 can be held stably in both hands of the user.

[0032] The suction device 100 has an elongated horizontal metal body 110 formed from a front metal tube 120 and a rear metal tube 130 telescopically connected together so as to form a coextensive passage within the metal body 110 . The cross section of the front pipe 120 is circular, and the cro...

Abstract

The dust collector for electric hand drill with bit and handle has an elongated body with front inlet and back outlet; an adaptor matched with the handle; a cover with side extendnig part, inner terminal connected to the front inlet, outer terminal extending beyond the bit and front end for pushing against wall and sealing drill area; and hose connected to the outlet of the vacuum dust collector. The passage to the inside of the cover produces suction to remove dust produced while drilling. The elongated body has back tube and front tube connected telescopically to the back tube. The elongated body has also a brake fixed on the front tube and with adjustable position, and the brake is near the back tube to limit its elongation with the front tube being capable of being withdrawn into the back tube.

Description

technical field [0001] The present invention relates to a dust suction (or suction) device for a hand-held power tool such as a hand drill, which can remove dust and / or debris generated when the power tool is in operation. Background technique [0002] Dust suction devices of this type are generally known for electric hand drills. One type incorporates a suction device into the drill body and is actuated by the hand drill's motor to generate suction. Its structure is very complex and the additional load limits the performance of the motor. Another type is to use the suction device with the external vacuum cleaner through the handle of the drill, but this configuration is still complicated. [0003] The object of the present invention is to solve or at least alleviate the above-mentioned problems by proposing an improved dust suction device. Contents of the invention [0004] The invention provides a dust suction device for a hand-held power tool. The hand-held power too...
