Angle-adjustable electric tool

Abstract

The invention discloses an angle-adjustable electric tool. The angle-adjustable electric tool comprises a working unit; a driving device is arranged in the machine body unit and used for driving the working unit to work; the handle unit is used for holding the electric tool; the machine body unit is connected with the handle unit through a second connecting mechanism, and the second connecting mechanism comprises a first connecting structure connected with the machine body unit; the second connecting structure is connected with the handle unit, and the first connecting structure is rotatably connected with the second connecting structure; the third locking unit is connected with the first connecting structure and / or the second connecting structure, and when the third locking unit is locked and / or unlocked, the connecting state of the machine body unit and the handle unit is switched between the positioning state and the adjustable state. According to the angle-adjustable electric tool, the angle between the handle unit and the machine body unit can be flexibly adjusted, the limitation caused by fixed connection of the handle unit and the machine body unit in the prior art is solved, and the angle-adjustable electric tool is simple in structure and good in flexibility.

Description

[0001] The present invention is a divisional application, its parent application number is 202011347926X, the application date is November 26, 2020, and the name is an electric tool with adjustable angle. technical field [0002] The invention relates to the field of tools, in particular to an electric tool with adjustable angle. Background technique [0003] Existing hand-held electric tools such as polishing machines generally include three components: a fuselage unit, a handle unit and a polishing work unit, wherein the polish work unit is connected with one end of the fuselage unit and is used to drive the The motor and other driving devices of the polishing work unit are often arranged in the handle unit, and then the output power of the motor and other driving devices is transmitted to the body unit and the polishing work unit by using a series of gear transmission structures arranged between the fuselage unit and the handle unit , used for polishing paint surfaces on ...

AI Technical Summary

Problems solved by technology

[0005] Existing hand-held electric tools of this type have the following deficiencies: (1) Since this type of electric tool itself is relatively large and heavy, and requires a high degree of control over strength during polishing, it is often thrown away when the strength is too high. Wearing the painted surface of cars, ships, etc., the force is too small and cannot achieve a good polishing effect. Therefore, when using this type of electric tool to polish, it is often affected by its own body shape and structure and has certain requirements for the operating space. The position of the bevel gear and other intersecting shaft transmission structures between the handle unit and the fuselage unit needs to be fixed, so that the handle unit and the fuselage unit can only be arranged at right angles or other fixed angles, which is inconvenient in some complex-structured operating spaces (2) Since the driving device is set in the handle unit, it is necessary to transmit the power of the driving device through intersecting shaft transmission structures such as bevel gears that cooperate with each other between the fuselage unit and the handle unit. The structure is complex; (3) The transmission structure of intersecting shafts such as bevel gears needs to be highly coordinated, so there is often a problem with the fit between the angle and position of the parts in the handle unit and the parts in the fuselage unit during production and processing or product assembly. Higher requirements, higher difficulty in production, processing or product assembly
