Carpet Air Kicker

Abstract

A carpet air kicker comprises a body, a rod, a spring and a controlling switch. The body defines an interior chamber including a front chamber and a rear chamber. A front end and a rear end of the rod have a gripping head and a piston respectively. The piston is located in the interior chamber such that the front chamber is not communicated with the rear chamber. A piston assembly of the body is connected to the rod and located between a front end of the body and the front chamber. The spring is installed in the rear chamber. A communicating hole is communicated with the front chamber. The controlling switch controls the front chamber communicated with external air such that the spring pushes the rod moving forward or communicated with an air compressor such that an air pressure pushes the rod moving backward.
