Polishing tool

Abstract

The invention provides a polishing tool. The polishing tool comprises a bottom plate assembly, a machine shell assembly, a driving mechanism and a supporting frame, wherein the bottom plate assembly comprises a bottom plate and a polishing part fixed to the bottom plate; the machine shell assembly is arranged on the bottom plate and comprises a machine body machine shell; the driving mechanism is arranged to drive the bottom plate assembly to move; the supporting frame is arranged between the machine body machine shell and the bottom plate and comprises a supporting seat, a center releasing part and a floating connecting arm; the supporting seat is arranged between the machine body machine shell and the bottom plate; the center releasing part is directly or indirectly fixedly connected to the bottom plate; and the floating connecting arm is connected between the center releasing part and the supporting seat and allows the supporting seat and the center releasing part to move relatively when the supporting frame is subjected to axial and / or radial acting force.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a grinding tool. Background technique [0002] Grinding tool is a kind of commonly used electric tool, realizes polishing and grinding on the surface of materials such as wood, plastics, stone, metal through the swing of bottom plate. On the basis of satisfying the grinding function, the hand-held grinding tool should usually have a small volume and dead weight, so as to meet the user's expectation of convenient operation and user experience. [0003] The function of the vibrating support in the grinding tool is to support the fuselage and the bottom plate, and make the bottom plate swing with the eccentric parts under the premise of the machine body not moving. The existing vibrating support generally includes a base, a top seat, and a vertical or curved connection. The support bar between the top base and the base, where the base and the top base are fixed to the bottom...

Problems solved by technology

[0003] The function of the vibrating support in the grinding tool is to support the fuselage and the bottom plate, and make the bottom plate swing with the eccentric parts under the premise of the machine body not moving. The existing vibrating support generally includes a base, a top seat, and a vertical or curved connection. The support bar between the top base and the base, where the base and the top base are fixed to the bottom plate and the fuselage respectively. When vibration occurs due to grinding during work, the vibration support will twist along with the bottom plate. At this time, the vibration support will be subjected to vertical direction and horizontal direction, so if the vibration support is set low, it is easy to break during use and the service life is low; if the vibration support is set high, although the service life is met, the height of the whole machine is high, and then The position of the center of gravity of the whole machine is raised, which affects the portability of the user's operation and is not conducive to improving the user's sense of control
