Claims

[Scope of utility model registration request]

A main body 3 is fitted into an outer guide 2 having a vertically long oval shape with an open left side so as to be slidable in the left-right direction. When the main body 3 comes into contact with the left end surface of the main body 3, the left end surface of the main body 3 is located slightly inward from the left end surface of the outer guide. A through-hole 3A having a cross-sectional path is formed on the end surface of the main body 3, and an inner guide 4 is fitted into the through-hole 3A so as to be slidable in the left-right direction. A handle 5 is provided at the center of the right end, protruding toward the right, and a spring holder 6 is fixed to the handle 5, and a spring holder 6 is secured between the holder 6 and the two right walls of the outer guide 2. A first compression coil spring 7 is attached to the inner guide 4, and a shaft 8 protruding rightward from the right end surface of the inner guide 4 is inserted into the spring receiver 6 so as to be able to move forward and backward. A driving tool for preventing wood end splitting, characterized in that a second compression coil spring 9 is installed between the right end faces of the inner guide 4.
