[0017] The utility model will be further described below in combination with the drawings and specific embodiments.

[0018] Embodiment 1

[0019] As Figure 1 Shown, the curved arm clamping mechanism in the example includes lifting mechanism 1112, fixed seat 1111, curved arm 1115, connecting rod 1114, mounting seat 1113, sliding block 1116, fixed seat 1111 is fixed lifting mechanism 1112, lifting mechanism 1112 is like the mechanism that the object connected can move in longitudinal direction, commonly like telescopic cylinder, gear and rack lifting, screw lifting etc., in the example, telescopic cylinder is shown by example.

[0020] The moving end of lifting mechanism 1112 is fixed mounting seat 1113, and the opposite position on mounting seat 1113 is respectively hinged connecting rod 1114, and the other end of connecting rod 1114 is connected with the first end of curved arm 1115, specifically, the first end of connecting rod 1114 is hinged with the side position on mounting seat 1113, the tail end of connecting rod 1114 is hinged with the first end of curved arm 1115, and the middle of curved arm 1115 is hinged with fixed seat 1111. Preferably, mounting seat 1113 is slidably connected with fixed seat 1111, which helps to improve the stability of movement.

[0021] The fixing base 1111 is connected with the sliding block 1116 in a relative sliding mode, and a waist hole 1117 is formed at the tail end of the curved arm 1115, and the curved arm 1115 is hinged with the corresponding sliding block 1116 through the waist hole 1117. In use, the cutter 111 is installed at the end faces of the two sliding blocks 1116 facing each other, the lifting mechanism 1112 moves the mounting seat 1113 up and down in the longitudinal direction, and the sliding blocks 1116 are moved towards or away from each other under the transmission of the connecting rod 1114 and the curved arm 1115.
