[0025] The utility model adopts four arc-shaped linkage plates 8, and drives the clamping mechanism 9 to rotate through the driving mechanism 7. The clamping mechanism 9 can drive the four arc-shaped linkage plates 8 to rotate around the axis of the rotating drum 61, and utilizes the cutting teeth 81 at the bottom of the four arc-shaped linkage plates 8 to cut the mortar, thereby improving the effect of cutting the mortar. After the cutting is completed, the four arc-shaped linkage plates 8 are driven to move synchronously through the clamping mechanism 9, and the four arc-shaped linkage plates 8 can quickly clamp the cut mortar.

[0026] The driving mechanism 7 includes an L-shaped bracket 71, a first motor 72, a gear 73 and a ring gear 74. The L-shaped bracket 71 is arranged on the top of the support plate 6, and the first motor 72 is vertically arranged on the L-shaped bracket 71. The gear 73 is fixedly connected to the output end of the first motor 72, and the ring gear 74 is fixedly installed on the outer wall of the rotating drum 61 near its top, and the ring gear 74 is meshed with the gear 73.
