Abstract
This practical new model makes an improved binding machine known to the public, which includes main body, handle, ratchet wheel, roller, fastening belt, latch reed spring, control plate. Among them, the handle's side board is linked with the main section's side board through torsion spring. In this manner, when the fastening belt needs to be tightened as the binding machine is being used, the user can press down the handle which will resume its initial position with the bounce force of the torsion spring. It is not necessary for the user to push it back to the initial position after pressing the handle down. It is very easy and labor-saving with higher efficiency. Furthermore, it can also set a coil spring in the outside end of the roller. The fastening belt can withdraw inside the main section automatically, which is very convenient.
