Background

When a workpiece is ground or polished, a grinding device such as a grinder is commonly used, and is popular with users due to convenience and flexibility. The sander is arranged in the machine shell and is used for providing a driving force, the driving device is connected with the working bottom plate through a transmission device, and the bottom surface of the bottom plate is attached with sanding materials such as sand paper. When the polishing machine works, the driving device generally drives the bottom plate component to eccentrically move, the bottom plate accessory attached to the bottom plate component correspondingly moves, and the working surface is polished, so that the bottom plate component is smooth and flat.

For different sanding operation environments, sanding machine base plates with different shapes, such as rectangle, circle, triangle and the like, are usually selected on the base plate of the sanding machine to meet different sanding working conditions. But the bottom plate and the grinder of current grinder adopt the screw to be connected usually, have the installation and dismantle inconvenient, waste time and energy scheduling problem when changing different bottom plates, and work bottom plate is changing the in-process, need loosen the fastener earlier until can follow the main part with work bottom plate and dismantle or separate, and spare part loses easily, and the installation is loaded down with trivial details, work efficiency is low. For such a problem, related solutions are also disclosed in the prior art, such as chinese patent No. ZL201020157053.1, the publication date is 2010, 12 and 01, and the name of the invention is: the application relates to a quick-change structure for a sander base plate, which comprises a sliding block arranged on an eccentric shaft bracket of a sander and a locking groove arranged on the sander base plate and matched with the sliding block, wherein the sliding block can move between a first position and a second position, the sliding block is reset to a position where the sliding block is separated from the locking groove through an elastic element at the first position, and the sliding block is poked into the locking groove through a poking piece arranged on the base plate and is clamped with the locking groove at the second position; two sliders are arranged on a bearing support of the sander, after a base plate to be arranged is pushed upwards to a position, the rotating base plate center stirs 90 degrees, the two sliders fixed on the bearing support can be stretched out simultaneously and are locked in the groove of the inserted base plate, when the base plate is disassembled, the stirring piece rotates 90 degrees, the two sliders can automatically withdraw from the locking groove on the base plate under the action of spring force, and the base plate is separated. The quick change structure operation process in grinder bottom of this application is simple, and the structure is firm, adapts to the bottom plate of multiple shape, but this application adopts slider, locking groove, elastic element and dials the piece cooperation and uses, sets up comparatively complicated structure and realizes breaking away from or the joint, brings great trouble to the shaping of moulding, and need rotate many times when using, and rotatory in-process inner structure blocks easily, brings the difficulty for tearing open the process of changing. For another example, as shown in the Chinese patent No. ZL201720818161.0, the date of the authorized announcement is 2018, 02 and 13, and the name of the invention creation is as follows: a quick-mounting base plate of a sander and the sander using the same relate to a quick-mounting base plate of a sander and a sander using the same, which comprises a base plate body and a base plate accessory, wherein a buckling mechanism and a locking mechanism are arranged between the base plate body and the base plate accessory, the base plate accessory and the base plate body are locked by the locking mechanism after being buckled by the buckling mechanism, the locking mechanism comprises a locking rod arranged on the base plate subject and a clamping hook arranged on the base plate accessory, a working part of the locking rod is pivoted on the inner side of the base plate body, a buckling part which can be buckled with or separated from the clamping hook by rotating the locking rod is arranged on the working part of the locking rod, the locking rod is also provided with a rotating handle for driving the working part to rotate, the base plate accessory and the base plate body of the sander are simple to disassemble and assemble, the operation is flexible and quick, and the quick disassembly of the base plate accessory is realized by adopting the locking, the process of connecting the base plate to the sander is not simplified.

In view of this, how to provide an easily removable sander base plate is an important subject to be solved at present by improving a sander in the prior art, which has a complicated installation process and is inconvenient to use of the sander base plate.
