[0012] A rapid demolition device of the present utility model will be further described in conjunction with the accompanying drawings.

[0013] A rapid demolition device of the utility model comprises two symmetrically arranged demolition pliers 1. The lower ends of the two demolition pliers 1 are formed with hinge parts 1-1. The two demolition pliers 1 are hinged through the hinge parts 1-1. A connecting component 2 is hingedly connected to the bottom of the two demolition pliers 1. The lower end of the connecting component 2 is connected with a manual hydraulic pump 3. The connecting component 2 comprises two symmetrically arranged transmission plates 2-1 and a Y-shaped connecting piece 2-2 hinged to the two transmission plates 2-1. The two transmission plates 2-1 are in a convex shape. An arc groove with an upward opening is formed at the upper end of each of the two transmission plates 2-1. The bottoms of the two demolition pliers 1 are respectively hingedly installed in the two arc grooves. The outer sides of the adjacent ends of the two transmission plates 2-1 are hinged through a pair of connecting pieces 2-3. An articulated groove with an obliquely outward opening is formed at the other end of each of the two transmission plates 2-1. The upper end of the Y-shaped connecting piece 2-2 is hinged in the two articulated grooves. The piston end of the manual hydraulic pump 3 extends upward out of the Y-shaped connecting piece 2-2 and the two connecting pieces 2-3 of the connecting component 2, and a work-shaped block 3-1 is fixed on the extending end.
