Of course, the front cushion column 14 and the rear cushion column 15 also have a deceleration effect, specifically as follows:

The first driving motor 7 is connected with a control circuit board, and can detect the current and control the start and stop and the forward and backward rotation of the first driving motor 7.

When cutting tiles, the cutter assembly 3 walks backwards along the cantilever beam 1. During the running of the cutter assembly 3, when the control circuit board detects an increase in current, the first drive motor 7 will automatically slow down, thereby adjusting the cutting speed.

When the cutter assembly 3 walks to the rear end of the cantilever beam 1, the rear cushion post 15 is firstly contacted with the rear support baffle 13, and the rear cushion post 15 is compressed to generate elastic deformation, so that the cutter assembly 3 is prevented from continuing to move backwards. At this time, the current of the first driving motor 7 increases due to the travel being blocked, and when the control circuit board detects that the current increases to a certain extent, the first driving motor 7 is controlled to stop, and the cutting is stopped. After waiting 5 seconds, the first drive motor 7 is again controlled to be started and reversed so that the cutter assembly 3 travels back to the front end of the cantilever beam 1.

When the cutter assembly 3 moves back to the front end of the cantilever beam 1, the front bumper post 14 is first contacted with the front support baffle 12, and the front bumper post 14 is compressed to elastically deform, so that the cutter assembly 3 is prevented from moving forward. At this time, since the travel is blocked, the current of the first driving motor 7 increases, and the control circuit board detects the current increase, the first driving motor 7 is controlled to be completely stopped, so that the cutter assembly 3 is stopped at the initial position.

More specifically, the gear 6 is a synchronous pulley, and the rack 5 is formed by expanding a synchronous belt. Namely, the utility model can use the synchronous pulley to replace the gear, and can use the unfolded synchronous belt to replace the rack 5, thus the cost is lower and the maintenance is convenient.
