Abstract

The utility model provides a cajon beating device, comprising a pedal plate, a first stand, a first strut, a line casing, a second stand, a second strut, a beating rod and a fixed rack. A tow line is threaded in the line casing. The tow line has a start end and a tail end. The first stand and the second stand are respectively equipped with a first rotating pole and a second rotating pole, which are capable of rotating reciprocatingly. The pedal plate drives the first rotating pole to rotate. Two ends of the first strut are fixed on the first rotating pole and the start end of the tow line, respectively. Two ends of the second strut are fixed on the second rotating pole and the tail end of the tow line, respectively. The beating rod is fixed to the second rotating pole. A cajon is clamped and fixed by the fixed rack. In this way, when the pedal plate is trodden to link the beating rod to beat the cajon, through the lever effect of the first strut and the second strut, the displacement of the tow line can be increased, and meanwhile the instant torque force is enhanced, thereby overcoming the friction between the tow line and the line casing and making the treading more smooth.
