Abstract

The invention discloses a frequency-variable impact multifunctional electric tool, which comprises a shell (13) and a handle (1), wherein the handle (1) is arranged at one side of the upper end of the shell (13). The frequency-variable impact multifunctional electric tool is characterized in that an inner-handle transmission shaft (2) is arranged in the handle (1), one end of the inner-handle transmission shaft (2) is connected with a crankshaft (4), the crankshaft (4) is arranged at the upper end of the shell (13) by a bearing (6), a plug hammer (7) is arranged in the middle segment of the shell (13), the top of the shell (13) is connected with the crankshaft (4) through a connecting rod (5), dual spring oscillators are arranged at the lower segment of the shell (13), and the lower ends of oscillators (8) of the dual spring oscillators are connected with a tool piece (16). The frequency-variable impact multifunctional electric tool solves the problem that a handheld outer power tool can not realize the high-frequency vibration beating function, is light and durable, and can realize the actions of hammering, shoveling, riveting, matting, cutting, carving, chiseling and the like.

Description

technical field [0001] The invention relates to a hand-held electric vibrating tool. Background technique [0002] Electric hand-held tools currently on the market are all for the purpose of realizing the rotating function, such as electric drills, etc., but lack electric tools for realizing the hitting function. When actions such as hammering, shoveling, riveting, matte, cutting, chiseling, chiseling, etc. are required, it is usually done manually or with pneumatic tools, but pneumatic tools can only vibrate at low frequencies and cannot achieve high-frequency vibrations. beat. Contents of the invention [0003] The technical problem to be solved by the present invention: Aiming at the problem that the hand-held external power tools on the market cannot realize the high-frequency vibration striking function, a frequency conversion impact multifunctional electric tool is provided. [0004] Technical scheme of the present invention: [0005] A variable frequency impact m...
