Electric hammer drill capable of preventing displacement

Abstract

The invention discloses an electric hammer drill capable of preventing displacement. The electric hammer drill capable of preventing displacement is characterized in that a sleeve is arranged in a shell, an impact hammer is arranged in the sleeve, the impact hammer is fixed in the sleeve through a bearing, one side of the impact hammer is connected with a rotating shaft, the rotating shaft is connected with a connecting rod mechanism, the connecting rod mechanism is connected with a transmission shaft, the transmission shaft is connected with a rotary motor through a transmission gear and a driving gear, the sleeve is connected with a muzzle, and the other side of the impact hammer is connected with a drill bit. According to the electric hammer drill capable of preventing displacement, twopairs of positioning feet can be installed on the muzzle, the drill bit is assisted by the operator to fix the drill bit on the drill point under the condition that the drill bit is aligned with thedrilling point, so that the phenomenon that the drill bit does not move when the drill bit works is guaranteed.

Description

Technical field [0001] The invention relates to an electric hammer drill device, in particular to an electric hammer drill capable of preventing displacement. Background technique [0002] Today, after many years of practice in the construction field, the construction field has been subdivided into many branch fields for in-depth research. With the development of modern technology, many highly professional tools have appeared in different fields. Electric drill hammers are the home improvement field in the construction field. One of the commonly used tools, the electric drill hammer can work well on the wall, and the suitable size mounting holes are drilled on the wall for fixing various objects and equipment on the wall. However, the existing electric hammer drill When drilling the wall, the operator is required to continuously apply force to the electric hammer drill with both hands to ensure that during the drilling process, the drill bit will not shift in position due to the ...

[0002] Today, after many years of practice in the field of construction, the field of construction has been subdivided into many branches for in-depth research. With the development of modern technology, many highly professional tools have appeared in different fields. One of the commonly used tools, the electric hammer drill can work well on the wall, and drill out the installation holes of suitable size on the wall, so that various items and equipment can be fixed on the wall, but the existing electric hammer drill When drilling on the wall, the operator needs to continuously apply force to the electric hammer drill with both hands to ensure that the drill bit will not shift due to the impact force generated during drilling. This not only requires It consumes a lot of physical strength of the operator, and there is no guarantee that the drill bit will not deviate. Once the deviated drilling hole is damaged, it will not only make the equipment unable to be installed, but also affect the appearance of the wall
