BACKGROUND OF THE INVENTION
Please refer to FIG. 11, which shows a perspective view of a carpet kicker of conventional technology. A carpet kicker 9 comprises a rod 90, a gripping head 91 and a knee pad 92. The gripping head 91 is located in a front end of the rod 90. The knee pad 92 is located in a rear end of the rod 90. A user uses his hand(s) to hold the rod 90. The gripping head 91 engages a carpet 93. And then the user uses his knee to kick the knee pad 92 to install the carpet 93. The conventional carpet kicker 9 needs manpower for carpet 93 installation.
