Abstract
A pair of symmetrical positioning clamps are provided for use in a table-top circular saw. Each positioning clamp essentially comprises a support plate with an increasing width toward an abutment plate which is connected to the support plate at right angles. Also, an elongated slot is formed approximately along the center line of the support plate. Furthermore, the support plate is arranged obliquely relative to the abutment plate so that the center line of the elongated slot is at an angle of 60.degree. to the abutment plate. The two positioning clamps are fixed to both wing portions of the circular saw by tightening wing bolts inserted into holes in the wing portions via the elongated slots. To clamp a work piece, the wing bolts are loosened with the work piece pressed against a fence of the circular saw. Then, the abutment plates are slid until they firmly abut on the work piece. Subsequently, the wing bolts are tightened again to secure the clamps with the support plates extended at an angle to the work piece.
