The second spring 41 pushes the inclined block 42 to insert the inclined block 42 into the slot 34, thus fixing the locking tooth 33. The inclined block 42 can be pulled from the outside by the pull rope 43 to remove it from the slot 34.

[0030] The working principle of this utility model is as follows: The object to be carved is placed on two rotating rollers 11. The motor 13 drives the second gear 14 to rotate, and the rotating rollers 11 on both sides rotate through transmission, which in turn drives the object to be carved to rotate. When the object to be carved is placed on the rotating rollers 11, the rectangular column 23 extends and retracts, so that the two ends of the object contact the two fixed plates respectively. By pressing and pulling the plate 32, the locking teeth 33 are inserted into the tooth groove 25, and the inclined block 42 is squeezed into the slide groove 4. When the locking teeth 33 are inserted into the tooth groove 25, the locking groove 34 engages with the inclined block 42. The second spring 41 pushes the inclined block 42, so that the inclined block 42 is inserted into the locking groove 34, thus fixing the locking teeth 33. The fixed plates clamp and fix the object. When it is necessary to drive the object to rotate, the electric telescopic rod 2 drives the first fixed plate 21 to retract, thus releasing the fixation of the object.
