Decorative strip cutting device

The invention discloses a decorative strip cutting device which comprises a clamping mechanism. The clamping mechanism comprises a profiling sliding block, a clamping driving mechanism, a fixing base and a clamping assembly. The hinged end of the clamping assembly is hinged to the fixing base. The movable end of the clamping driving mechanism is hinged to the hinged end of the clamping assembly and connected with the fixing base in a relative sliding mode, and the clamping driving mechanism is used for controlling opening and closing of the clamping assembly. The clamping assembly comprises a female die and a male die opposite to the female die. The profiling sliding block is connected with the male die in a relative sliding mode, and when the female die and the male die are assembled and the profiling sliding block abuts against the end, away from the clamping driving mechanism, of the female die, the profiling sliding block, the female die and the male die form a clamping gap matched with a workpiece to be
