Claims

[Scope of utility model registration request]

A square chisel machine main body 1, which is equipped with a square chisel blade 4, a feed screw rod 5, and a motor for rotationally driving these, is guided in reciprocation by guide bars 9, 9 supported by a base 10, and is attached to the base. In the square chisel machine, which is provided so that the main body of the square chisel machine is held by clamping the workpiece 13 in the vise part 14, a support holder 6 is fixed to one end of the guide bar, and the feed A feed nut 21 externally screwed onto a threaded rod is installed so that it can slide only in the axial direction via a rotation prevention means 22, and the screw connection with the feed nut can be released at both ends of the movement range of the square chisel machine body. Thread missing parts 23 and 24 are respectively provided at both ends of the feed screw rod so that the feed nut and the feed screw rod are released at both forward and backward movement ends of the square chisel machine main body. A cutting feed device for a square chisel blade in a square chisel machine, characterized in that a spring 25 presses and biases the screw in the direction of screwing into the feed threaded rod.
