Problems solved by technology

[0002] Hand saws are popular because of their lightness, flexibility, quickness and practicality, and become household items and essential items. However, general hand saws use nuts to tighten the saw blade, and the tightening force varies from person to person. Sometimes the power is insufficient, which can easily lead to the breakage of the saw blade, and its frame is generally made of steel material, which makes the whole manual saw heavy in weight, which is not conducive to carrying, and even increases the labor intensity of the user

[0003] The society also has a kind of hand saw that changes saw blade more conveniently at present, as the patent No. ZL200410066603.8 Chinese Invention Patent "Handsaw for Immediately Changing Saw Blade" (Notice No. is CN1586778A) is exactly this kind of design; The swing cover is connected with the saw blade; although this design can realize the quick replacement of the saw blade, the swing cover is set on the bottom side, and the fastening is realized by the connecting rod pierced in the round hole of the swing cover, which is easy to cause Slippage of the saw blade, and the opening and closing of the swing cover are inconvenient due to the short arm; at the same time, the back bend part hinged with the swing cover has no wear-resistant block or hard object at the place where it conflicts with the frame beam. , so that the two conflicts are easy to wear, reducing the service life and accuracy of the manual saw
