Abstract
A dustproof electric drill comprises a main machine and a rear handle below the main machine; a drill stem is connected with the output shaft of the main machine; a blade cover is sleeved outside the output shaft; the blade cover is located in an annular cavity; the annular cavity is connected with a protective shield through a conduit; the head of the drill stem passes through the protective shield; the lower side of the conduit is communicated with a hollow front handle. The dustproof electric drill is able to collect the dust generated in the usage process, thus ensuring the environment not to be polluted; and the health of the user cannot be affected.
Description
Technical field
The invention belongs to field of power tools, particularly the dust-proof bits electric drill of one.
Background technology
Electric drill is one of conventional electric tool, for boring, punching etc., has number of different types.But no matter which kind of electric drill, all can produce a large amount of dusts and scrap in the course of the work, not only contaminated environment, also cause very large infringement to the health of user.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of dust-proof bits electric drill, the dirt bits produced in use procedure can be collected, keep workplace neat and tidy, also protect the health of user simultaneously.
To achieve these goals, the technical solution used in the present invention is:
A kind of dust-proof bits electric drill, the rear handle 1 comprising main frame 2 and be positioned at below main frame 2, drilling rod 5 connects the output shaft of main frame 2, blade cover 4 is connected in the outer cover of described output shaft, blade cover 4 is arranged in toroidal cavity 5, toroidal cavity 5 connects guard shield 6 by conduit 7, and the head of drilling rod 5, through guard shield 6, is communicated with hollow front handlebar 9 below conduit 7.
The upper end connecting duct 7 of described front handlebar 9, lower end arranges plug 8.
Compared with prior art, the dust collecting that the present invention can will produce in use procedure, thus ensure that environment is not contaminated, also can not impact the health of user.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of dust-proof bits electric drill, the rear handle 1 comprising main frame 2 and be positioned at below main frame 2, drilling rod 5 connects the output shaft of main frame 2, is connected to blade cover 4 in the outer cover of described output shaft, and blade cover 4 is arranged in toroidal cavity 5, toroidal cavity 5 connects guard shield 6 by conduit 7, the head of drilling rod 5 is through guard shield 6, and the upper end connecting duct 7 of front handlebar 9, lower end arranges plug 8.
During use, main frame 2 drives drilling rod 5 rotation work, and the dirt bits boring movable property raw fall into guard shield 6.Blade cover 4 also rotates simultaneously, and in toroidal cavity 5, produce certain air-flow, the absorption affinity that air-flow brings acts on guard shield 6 by conduit 7, dirt bits are posteriorly inhaled dynamic, drops in hollow front handlebar 9, after a period of time, Shutdown Hosts, open plug 8 clear up in front handlebar 9 dirt bits.
