Abstract

The invention discloses a buffering variable frequency impact type multifunctional electric tool comprising a housing (13) and a handle (1), wherein the handle (1) is mounted on one side at the upper end of the housing (13); an in-handle transmission shaft (2) is mounted in the handle (1); one end of the in-handle transmission shaft (2) is connected with a crankshaft (4); the crankshaft (4) is mounted at the upper end of the housing (13) through a bearing (6); a plug hammer (7) is arranged in the middle section of the housing (13); the top of the plug hammer (7) is connected with the middle of the crankshaft (4) through a connecting rod (5); a double-spring oscillator is mounted at the lower section of the housing (13); and the lower end of the oscillator (8) of the double-spring oscillator is connected with a tool piece (16). According to the multifunctional electric tool, the problem that a handheld external power tool cannot perform a high-frequency vibration impacting function is solved; the weight is light; the structure is durable; and functions of hammering, shoveling, riveting, matting, cutting, carving, chiseling and the like can be realized.

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 striking 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. Hit, and existing pneumatic tools can't cushion when encountering hard objects during work, and the tool head can't be driven in, and reaction force can make tool itself bounce back, and may cause harm to human body. Contents of the invention [0003] The technical problem to be solved by the present invention: Aiming at the problems that the hand-held external power tools on the market cannot realize ...
