Abstract
The article of the design is a rail fastening tool used to fasten a rail to a support such as a sleeper or track slab with a leaf spring, as shown in the reference drawings showing the functions of each part. When not in use, the arm fixing block and the fixing claw are closed (folded) on the arm side, as shown in the right side view showing the state before use, and when in use, the arm fixing block and the fixing claw are opened (deployed) from the arm side, as shown in the right side view showing the state in the middle of compressing the leaf spring. This rail fastening tool is inserted between the rail and the leaf spring, as shown in Reference Figure 1 showing the state in use, and compresses the leaf spring with the tip of the arm while pushing down the arm, as shown in Reference Figure 2 showing the state in use, and forms a gap for inserting an adjustment washer between the leaf spring and the fixing member, as shown in Reference Figure 3 showing the state in use.
