Abstract

The invention belongs to the technical field of electric tools and relates to a double-speed multifunctional electric hammer. It includes front-end and rear-end components; front-end components include front-end housing, base, transmission shaft assembly, impact shaft assembly, sliding pinion assembly, low-speed large gear, high-speed large gear, large gear return spring, inner and outer knobs, and low-speed slide plate , High-speed skateboards, skateboard springs, anti-rotation plates, etc. The invention realizes the conversion of five functions of the electric hammer, such as single hammer, neutral gear, hammer drill, low-speed drill, and high-speed drill, with one knob, and has reliable function and convenient installation and use. The method solves the problem that the efficiency of the existing electric hammer is not high when drilling small holes on steel and wood.

Description

technical field [0001] The invention belongs to the technical field of electric tools in the machinery industry, and in particular relates to a two-speed multifunctional electric hammer which uses a single knob to realize five functions of single hammer, neutral gear, hammer drill, low-speed drill and high-speed drill. Background technique [0002] Existing electric hammers have at most four functions, i.e. single hammer, neutral gear, hammer drill, and low-speed drill. The single hammer function is generally used to chisel wire grooves on cement and brick walls and shovel ceramic tiles; the neutral position is used to adjust the angle between the cutting edge of the flat chisel and the working surface, so that the operator can hold the electric hammer comfortably when working; The hammer drill function is generally used to drill holes in cement and brick walls; the low-speed drill function is generally used to drill holes larger than φ10 in steel and wood. However, the low...
