[0028] The polishing sheet 2 is arranged on a reciprocating polishing machine through the base 1, and the reciprocating polishing machine drives the polishing sheet 2 to reciprocate to polish the workpiece. The polishing sheet 2 is triangularly arranged, which is beneficial to polishing the edges and corners of the workpiece.

Multiple groups of fixing blocks 22 arranged on the back surface of the polishing sheet 2 are fixed on the base 1 by matching with the connecting component 3 arranged on the base 1, which is convenient to be further connected with the grinding machine through the base 1. The multiple groups of fixing blocks 22 are respectively arranged at the three vertex angles of the polishing sheet 2, which is beneficial to supporting the end of the polishing sheet 2 far from the base 1 through the connecting component 3 to ensure the stable fixation of the polishing sheet 2. The first telescopic component 11 can be made of an electric telescopic rod. The two ends of the first telescopic component 11 are respectively connected with the connecting component 3 and the base 1. Driving the connecting component 3 to move through the first telescopic component 11 is beneficial for the connecting component 3 arranged on the base 1 to be mutually matched and connected with the fixing blocks 22 arranged on polishing sheets 2 of different specifications, enabling the base 1 to install multiple polishing sheets 2 of different specifications, while preventing the base 1 from being too large to interfere with the grinding of the edges and corners; or the base 1 is too small to support and fix the part of the polishing sheet 2 far from the base 1. The fixing groove 32 that is mutually clamped and matched with the fixing block 22 is arranged on the fixing plate 31 in the connecting component 3, which is convenient for fixing the polishing sheet 2 and the connecting component 3. The first elastic member 34 and the second elastic member 36 can be made of springs. Driving the first abutting plate 33 and the second abutting plate 35 to move towards the fixing block 22 respectively through the first elastic member 34 and the second elastic member 36, so that they are mutually abutted and matched with the fixing block 22, is beneficial for the connecting component 3 to fixedly connect the polishing sheet 2 through the fixing block 22.
