[0037] The upper arc-shaped shell 2012 and the lower fan-shaped shell 2022 are respectively fixed to one side of the upper mounting seat 2011 and the lower mounting seat 2021, and the upper arc-shaped shell 2012 and the lower fan-shaped shell 2022 are spliced ​​up and down and distributed on the grinding wheel 104, and the upper arc-shaped shell 2012 and the lower fan-shaped shell 2022 can shield the debris generated by the grinding of the grinding wheel 104;

[0038] The force balancing unit includes a horizontal seat 204 and a ball 205;

[0039] The horizontal seat 204 is symmetrically formed at the two ends of the bottom of the lower fan-shaped shell 2022, and the ball 205 is rotatably connected to the inner side of the horizontal seat 204 and protrudes from the upper and lower ends of the horizontal seat 204. There are multiple balls 205 evenly distributed horizontally along the track of the horizontal seat 204;

[0040] The lowest point of the grinding wheel 104 is lower than the lowest point of the ball 205. When the grinding wheel 104 is grinding, the bottom of the ball 205 rolls against the surface of the stainless steel product, so that the contact force between the grinding wheel 104 and the stainless steel product is uniform.

[0041] The adjustment unit includes an arc-shaped guide block 203, a handle 206, and a positioning screw 207;

[0042] The arc guide blocks 203 are symmetrically fixed to the inner sides of the upper mounting seat 2011 and the lower mounting seat 2021. The outer side of the fixing seat 102 is provided with a limiting ring groove 105 for the two arc guide blocks 203 to be inserted into. The arc guide blocks 203 cooperate with the limiting ring groove 105 to provide guidance for the rotation of the upper protective member 201 and the lower protective member 202.

[0043] The top of the upper mounting seat 2011 protrudes above the upper arc-shaped shell 2012, and the handle 206 is fixed to one side of the upper mounting seat 2011 and is parallel to the upper arc-shaped shell 2012, and the handle 206 is used for the operator to hold and grasp;

[0044] The positioning screw 207 passes through the arc guide block 203 from the top of the upper mounting seat 2011 to the inner side of the limiting ring groove 105. A plurality of locking holes 106 are provided in a ring shape at the bottom of the inner wall of the limiting ring groove 105. The bottom end of the positioning screw 207 is inserted into a locking hole 106 to lock the position of the upper protective member 201 and the lower protective member 202. The bottom of the positioning screw 207 is separated from the locking hole 106 to allow the upper protective member 201 and the lower protective member 202 to rotate.

[0045] In this embodiment, it should be supplemented that the grinding wheel 104 is a type that uses the end surface (i.e., the surface facing the upper arc-shaped shell 2012 and the lower fan-shaped shell 2022) for grinding, and the grinding surface has a certain degree of shrinkage, such as a polishing fiber wheel, a sandpaper-containing brass wire wheel, etc. The debris generated by the grinding wheel 104 is oriented toward the arc-shaped shell 2012 and the lower fan-shaped shell 2022 in the direction, thereby intercepting the debris;

[0046] When grinding stainless steel products, one hand can hold the handle 206 and the other hand can hold the body 101, and then the horizontal seat 204 is parallel to the surface to be grinded and close to it, and finally the ball 205 is attached to the surface to be grinded, and there is a certain squeezing force between the end face of the grinding wheel 104 and the surface to be grinded, and the end face of the grinding wheel 104 will deform to adapt to the position of the surface to be grinded, and the driving structure inside the body 101 drives the driving shaft 103 to rotate, driving the grinding wheel 104 to rotate to grind the surface of the stainless steel product, and at the same time, the whole device is moved, and the roller 205 can roll freely, so that the squeezing force between the end face of the grinding wheel 104 and the surface to be grinded is kept uniform, and then the grinding is more uniform, which can effectively improve the grinding uniformity and improve the grinding efficiency;

[0047] It is also necessary to add that: the rolling of the roller 205 enables the entire device to automatically move in the horizontal direction, which can well achieve all-round grinding of the horizontal surface of the stainless steel product;

[0048] If it is necessary to change the grinding position, that is, other surfaces of the stainless steel product, when the surface angle changes, the auxiliary component 2 can be adjusted according to the needs, so that the fuselage body 101 can be at a comfortable hand-held angle, and the operation steps are as follows:

[0049] By loosening the positioning screw 207 to move it upward, when the bottom of the positioning screw 207 is separated from the locking hole 106, the auxiliary component 2 can be rotated as a whole. When the plane of the horizontal seat 204 is flush with the surface to be polished, the position of the auxiliary component 2 is determined by judging whether the relative angle between the body 101 and the handle 206 is convenient for holding. When the angle is appropriate, the positioning screw 207 can be tightened so that the positioning screw 207 moves downward and engages with a locking hole 106, thereby achieving the position fixation of the auxiliary component 2.

[0050] Through the above operations, the grinding operations on surfaces at different angles can be better performed, so that a more comfortable hand-held posture can be maintained during the grinding process, which can reduce fatigue during the grinding process.

[0051] Please refer to Figures 2 to 5 The end faces of the upper mounting seat 2011 and the lower mounting seat 2021 are formed with mounting plates for bolts to pass through and achieve fixation, and the interior of the upper mounting seat 2011 is formed with a thread groove for threaded fixation of the positioning screw 207.
