Electric hammer with drill bit cut-off and anti-throwing function

Abstract

The invention discloses an electric hammer with a drill bit cut-off and anti-throwing function. The electric hammer structurally comprises an electric hammer, a triangular mounting frame, an auxiliaryhandle, an adsorption device, a telescopic rod, wherein the adsorption device is composed of a pipe body, a deflation mechanism, a suction disc mechanism, a sealing cover and a surface plastering mechanism, and the working of the electric hammer is stabilized by utilizing the negative pressure principle, dust or garbage on the wall surface is cleaned through the surface plastering mechanism, thesucker mechanism is more stable during working, the adsorption capacity of the sucker cannot be influenced due to the fact that the wall surface rubbish or dust is large, the air is extracted according to the recovery performance after deformation of the air pressure ball, the residual air in the suction cup is extracted, the adsorption capacity of the sucker mechanism is further improved, the phenomenon that the electric hammer is suddenly broken in the rotating working state is avoided, the inertia throwing force is large, and the situation that the wrist sprain and even falls off and the like during operation of workers is caused.

Description

technical field [0001] The invention relates to the field of electric hammers, in particular to an electric hammer with the ability to prevent the drill bit from being thrown out. Background technique [0002] Some structures on the construction site cannot be completed at one time, such as wall planting, floating board planting, line planting, etc., all of which require secondary completion of the project, and electric hammers are required to drill holes when planting bars. The hammer uses the movement of the piston, and the compressed gas impacts the drill bit, which can drill holes in the concrete. However, due to the high strength of the concrete, the drill bit will rub against the concrete at high speed and generate heat, so it is easy to break and be thrown out. The throwing force is very large, and it is easy to cause the staff to sprain the wrist or even fall and get injured during the operation. In order to avoid this kind of situation, there is an urgent need for a...

[0002] Some structures on the construction site cannot be completed at one time, such as wall planting, floating board planting, line planting, etc., all of which require secondary completion of the project, and electric hammers are required to drill holes when planting bars. The hammer uses the movement of the piston, and the compressed gas impacts the drill bit, which can drill holes in the concrete. However, due to the high strength of the concrete, the drill bit will rub against the concrete at high speed and generate heat, so it is easy to break and be thrown out. The throwing force is very large, and it is easy to cause the staff to sprain the wrist or even fall and get injured during the operation. In order to avoid this kind of situation, there is an urgent need for a hammer that can prevent the electric hammer from being thrown out during work and increase the stability of the work.
