Description

Gun drill with brush

Technical Field

The utility model belongs to the technical field of electric tools, and particularly relates to a brushed pistol drill.

Background

The electric drill is an electric tool driven by a motor to drive an output shaft, is widely applied to industries such as building, decoration, furniture and the like, and is used for perforating or penetrating objects on articles.

The existing pistol drill is easy to cause the problem of hand fatigue of a user due to the influence of vibration factors of an internal motor in the drilling process. It is therefore necessary to relate to a brushed pistol drill.

Disclosure of Invention

Aiming at the problems, the utility model provides the brushed pistol drill, which can effectively improve the anti-seismic effect.

In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a brush pistol drill, includes the casing and arranges drill bit and brush motor in the casing in, and this brush motor one end is provided with the brush, brush motor's output shaft passes the brush and connects in the meshing tooth, the meshing tooth meshing is connected in rotating the tooth, the spacing assembly of drill bit is in the middle of rotating the tooth, the casing comprises antidetonation composite sheet, and this antidetonation composite sheet includes antidetonation layer and antidetonation sponge.

Preferably, one end of the brush motor is electrically connected through an electric wire.

Preferably, a key is further arranged in the shell, and the key is electrically connected with the brush motor.

Preferably, the anti-seismic layer is made of synthetic rubber.

Advantageous effects

Compared with the prior art, the utility model has the beneficial effects that:

when the pistol drill vibrates, the vibration sense is transmitted to the anti-vibration composite board of the shell, and is weakened through the anti-vibration layer and the anti-vibration sponge, so that the vibration sense transmitted to a user is further reduced, and the problem of hand fatigue of the user is effectively solved.

Detailed Description

The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, which are schematic structural views of a brush gun drill according to a preferred embodiment of the present utility model, the embodiment includes a casing 10, a drill bit 20 and a brush motor 30 disposed in the casing 10, one end of the brush motor 30 is provided with a brush 31, an output shaft of the brush motor 30 is connected to a meshing tooth 50 through the brush 31, the meshing tooth 50 is connected to a rotating tooth 40, the drill bit 20 is limitedly assembled in the middle of the rotating tooth 40, the casing 10 is composed of a shock-resistant composite plate 11, the shock-resistant composite plate 11 includes a shock-resistant layer 111 and a shock-resistant sponge 112, and when the gun drill vibrates, shock is transmitted to the shock-resistant composite plate 11 of the casing 10, and is weakened by the shock-resistant layer 111 and the shock-resistant sponge 112, so as to further reduce shock transmitted to a user, thereby effectively solving the problem of hand fatigue of the user.

In this embodiment, one end of the brush motor 30 is electrically connected by an electric wire, and the brush motor 30 starts to work after being electrified, so as to drive the drill bit 20 to rotate.

In this embodiment, a key is further disposed in the casing 10, and is electrically connected to the brush motor 30, and the brush motor 30 works when the key is powered on after being pressed, so as to ensure normal use of the pistol drill.

In this embodiment, the shock-resistant layer 111 is made of synthetic rubber, and the shock feeling is effectively weakened by the elastic force of the rubber.

The foregoing is a further elaboration of the present utility model in connection with the detailed description, and it is not intended that the utility model be limited to the specific embodiments shown, but rather that a number of simple deductions or substitutions be made by one of ordinary skill in the art without departing from the spirit of the utility model, should be considered as falling within the scope of the utility model as defined in the appended claims.
