Vibrating tamper for constructional engineering

The utility model belongs to the technical field of constructional engineering, and particularly relates to a vibrator for constructional engineering, which comprises a vibrator body and a dismounting component mounted on the surface of the vibrator body, the dismounting component is arranged on the vibrator, and a user firstly pulls a connecting rod through the dismounting component and then pulls the connecting rod through the connecting rod. According to the device, the vibrating rod which is damaged after being used for a long time can be quickly replaced, the motor in the vibrator body and the vibrating rod do not need to be integrally replaced, a large amount of resource waste is reduced, and the working efficiency is improved. A pulling assembly is additionally arranged on the mechanism, a pull rod on the surface of one side of a connecting block is pulled firstly, the pull rod drives a fixing plate to move, the pull rod drives a protective cover to move in the moving process, concrete is prevented fro
