FIG. 1 is a view of the structure of the drilling apparatus of the present invention;

FIG. 2 is a drawing of a second embodiment of the drilling apparatus of the present invention;

FIG. 3 is a third drawing showing the construction of the drilling apparatus of the present invention.

Detailed Description

Embodiment 1, as shown in fig. 1, 2 and 3, this embodiment is a drilling device that can drill holes on walls, ceilings, etc. during decoration, and is actually an electric drill, as shown in fig. 1, the drilling device includes a drill bit 1, a main body 2 that drives the drill bit 1 to rotate, and actually, a motor is provided in a main body housing, the motor drives the drill bit 1 to rotate at a high speed, and the drill bit 1 can drill into the walls or ceilings to drill holes on the walls or ceilings. The main body 2 is provided with a handle 3 for operating the drilling device, and a worker holds the handle 3 for operation. The drill bit 1 extends out of the shell of the main machine 1 and is fixed with an output shaft of a motor in the main machine; in this embodiment, in order to guarantee in the work progress, the environment is clean and tidy, the dust that produces when preventing that the electric drill from drilling flies upward, cause environmental pollution or injury workman, especially when workman's handheld electric drill drills to the ceiling that pushes up, prevent that the dust that produces from entering into workman's eyes, still include dust collection device, dust collection device includes bowl-shaped dust arrester 4, bowl-shaped dust arrester 4 is fixed on the host computer, it is exactly to set up the dust arrester 4 of a bowl-shaped at the electric drill head and catch the dust that produces in fact, consequently, bowl-shaped dust arrester 4 should be around drill bit 1, still include dust collecting sleeve 5, dust collecting sleeve 5 overlaps drill bit 1 outside, the bowl mouth sealing connection of bottom and bowl-shaped dust arrester 4. In this embodiment, the dust collecting sleeve 5 is a silica gel sleeve, which is sleeved around the drill bit, and when the drill bit 1 drills, it extends from the top of the silica gel sleeve, and the silica gel sleeve is provided with a plurality of folds to facilitate contraction, such as an accordion bellows, which is a telescopic sleeve. In addition, a dust box 10 is further included, and the dust box 10 communicates with the bowl-shaped dust collector 4 through a duct 11. This embodiment uses a flexible glue pipe with dust collection box 10 and the intercommunication of bowl shape dust arrester 4, like this, the dust of collecting in the bowl shape dust arrester 4 just can be through flexible glue pipe flow to dust collection box 10 in, these dusts are the dust that produces when electric drill drilling mainly. In this embodiment, the bowl-shaped dust collector 4 and the dust collecting sleeve 5 are sleeved on the electric drill bit 1, and the end of the bowl-shaped dust collector 4 is provided with an outlet connected with the plastic hose. One end of the plastic hose is fixed at the end of the bowl-shaped dust collector 4, and the other end is connected with the dust box 10, so that dust (dust) is guided into the dust box 10 in real time.

In this embodiment, in order to guarantee that the dust can smoothly flow into dust collection box 10 from bowl shape dust arrester 4 in, after bowl shape dust arrester 4 installation, still adopt filter screen 6, filter screen 6 is the disc, and the excircle is sealed with collection dirt cover 5 inner walls, and the centre utilizes sealing washer 7 cover outside drill bit 1, still is provided with clamping ring 8 and hole retaining ring 9 between sealing washer 7 and filter screen 6, and clamping ring 8 presses on sealing washer 7, and hole retaining ring 9 installs between filter screen 6 and clamping ring 7.

In use of the drill of this embodiment, the bowl-shaped dust collector 4 is passed through the drill bit 1 and secured to the drill body. The dust collecting cover 5 is fitted over the bowl-shaped dust collector 4 to form a closed space for collecting dust. The filter screen 6 is buckled on the bowl-shaped dust collector 4 and can be freely assembled and disassembled in a clockwise direction and a counterclockwise direction.
