The implementation principle of the above embodiment is as follows:

the operator is changing the polishing belt. The operator first turns off the power supply to stop the operation of the apparatus body 1.

Then, the operator rotates the solenoid 63, and the solenoid 63 moves downward along the linear direction of the third slide block 61 itself as the solenoid 63 rotates. The solenoid 63 simultaneously drives the pressing plate 64 to move, so that the pressing plate 64 is separated from the contact with the first fixing plate 21.

Next, the operator stops rotating the screw 63 and moves the screw 63, and the screw 63 drives the third sliding block 61 to move along the linear direction of the guide rod 212. The third slider 61 is separated from the second slider 213 and kept at a predetermined distance.

Next, the operator rotates the knob 35, the knob 35 drives the connecting rod 34 to rotate, the connecting rod 34 drives the second conical gear 33 to rotate, and the second conical gear 33 drives the first conical gear 31 to rotate.

The first slide block 22 drives the first driven shaft 13 to move, and changes the distance between the first driven shaft 13 and the first driving shaft 12. The polishing belt is not tensed at this time. The operator takes the old polishing belt away and replaces it with a new polishing belt.

Then, the operator slowly rotates the knob 35 in the reverse direction, the knob 35 drives the second bevel gear 33 to rotate, and the second bevel gear 33 drives the first bevel gear 31 to rotate in the reverse direction. The first conical gear 31 rotates the screw 24 in reverse around the first fixing rod 23. And moves the first slider 22 to the initial position. Because the first slider 22 is fixed to the second slider 213. The first slider 22 moves the second slider 213. When the first slider 22 returns to the initial position, the side of the second slider 213 comes into contact with the side of the inner wall of the first slide groove 211. The belt is now in tension.

Finally, the operator moves the third slider 61 so that the third slider 61 comes into contact with one side of the second slider 213. And the screw 63 is reversed, and the screw 63 drives the pressing plate 64 to move along the linear direction of the third sliding block 61. When the pressing plate 64 is in contact with the first fixing plate 21 and the coil 63 itself cannot rotate any more, the operator stops rotating the coil 63.

Specifically, the third slide block 61 has a rectangular upper cross section, a cross section width matching the cross section width of the first slide groove 211, and a circular bottom cross section of the third slide block 61.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
