Abstract
The invention discloses an improved electric hand drill which comprises a shell, a drill chuck, a handle and a gripping handle. A motor is disposed inside the shell provided with an air inlet. The improved electric hand drill is characterized in that a silencing device which is a silencing tube is disposed on the upper portion of the shell, the silencing tub comprises an inner tube and an outer tube, silencing cotton is filled between the inner tube and the outer tube, and a plurality of reinforcing ribs are disposed inside the handle. The improved electric hand drill has the advantages of reasonable structure, low noise and long service life.
Description
Technical field
The present invention relates to a kind of electric tool, relate in particular to a kind of improved electric hand drill.
Background technology
Electric tool use is in daily life comparatively general.Electric tool in use can produce very large noise, on around personnel and user can cause very large impact.In addition, electric tool, in the process of using, because torsion is large, can produce very large vibration, and long-time operation not only can affect service life of electric tool, also can impact user's health.Therefore, should provide a kind of new technical scheme to address the above problem.
Summary of the invention
The object of the invention is: for above-mentioned deficiency, provide a kind of rational in infrastructure, noise is little, the improved electric hand drill of long service life.
For achieving the above object, the technical solution used in the present invention is:
A kind of improved electric hand drill, comprise housing, drill chuck, handle and gripping handle, described enclosure interior is provided with motor, described housing is provided with air inlet, the top of described housing is provided with silencing means, and described silencing means is hush pipe, and described hush pipe comprises inner layer pipe and outer tube, between described inner layer pipe and outer tube, be filled with silencing cotton, described handle inside is provided with many reinforcements.
The bottom of described gripping handle is provided with holder, and described holder is connected with the bottom of gripping handle.
The bottom of described holder and gripping handle is threaded connection.
A kind of improved electric hand drill of the present invention, top at housing is provided with silencing means, described silencing means is hush pipe, described hush pipe comprises inner layer pipe and outer tube, between inner layer pipe and outer tube, be filled with silencing cotton, such structural design can be so that the noise producing in the electric hand drill course of work obtains elimination to a certain extent, the harmful effect of avoiding it to cause operating personnel and surrounding environment.Handle inside is provided with many reinforcements, has strengthened durable degree and the service life of electric hand drill of the present invention.The bottom of gripping handle is provided with holder, and holder is connected with the lower thread of gripping handle, some findings etc. can be put in this holder, has strengthened practicality of the present invention.
Advantage of the present invention is: rational in infrastructure, noise is little, long service life.
