Vibrator for constructional engineering

The utility model provides a vibrator for constructional engineering, which comprises a tray, a motor, a handle and a vibrating rod. And the handle and the motor are both arranged on the tray. And thetray is connected with the vibrating rod through a linkage rod. And the plane vibration mechanism is arranged on the vibration rod. The plane vibration mechanism comprises a vibration disc and a sliding sleeve. And the sliding sleeve is in sliding fit with the vibrating rod. According to the vibrator for the constructional engineering, the tray, the motor, the handle, the vibration rod, the vibration disc and the sliding sleeve are arranged in a matched mode. Therefore, the concrete vibrating machine can have double functions of vibrating a concrete plane and vibrating the interior of concrete. And moreover, when the two parts are switched, the switching operation is faster and smoother by using the device disclosed by the utility model. And the use efficiency of the device is greatly improved. Meanwhile, due to
