[0024] Embodiment 2:

[0025] See also Figure 1 , 2, 4, 5, based on Example 1, the ends of the two supporting legs 2 that are away from each other are fixedly connected with a rotating column 200, and the rotating column 200 is rotatably connected to the mounting block 300.

Specifically, the upper end of the armrest 6 is symmetrically fixedly connected with a fixing part 7, and the rotating handle 8 is rotatably connected to the fixing part 7.

[0026] The working principle of the utility model is:

[0027] When the utility model is used, the mounting block 300 is connected to the track by the limiting wheel 301, and then the driving member 10 is turned on to grind the surface of the track by the grinding block 5, wherein the pressure spring 903 will always give a downward pressure to the grinding block 5, so that the grinding block 5 can be closely in contact with the track surface;

[0028] When it is necessary to adjust the grinding angle, first press down the rotating handle 8 with your hand to drive the traction rope 203 to pull the limit rod 201 to compress the reset spring 202. At this time, the limit rod 201 will disengage from the limit groove 303. When the limit rod 201 disengages from the limit groove 303, the angle of the entire grinding seat 1 can be adjusted by directly rotating the armrest 6, so as to grind the side of the track. When it is necessary to lock the grinding angle, release the rotating handle 8 so that the limit rod 201 can be inserted into the limit groove 303 again under the action of the reset spring 202. In this way, the angle of the grinding block 5 can be easily adjusted, thereby improving the grinding efficiency.
