[0003] According to the search, the Chinese utility model patent with the patent application number CN202122599775.3 discloses a folding saw, which comprises a handle and a saw blade. The handle is provided with a containing cavity. The handle comprises a first handle part and a second handle part. One end of the first handle part is rotatably connected to one end of the second handle part. The first handle part and the second handle part can be rotated to open the containing cavity or be rotated to close the containing cavity. The saw blade is rotatably connected to the first handle part. The saw blade can be rotated into the containing cavity or be rotated to the outside of the handle. The second handle part is provided with a limiting structure. The saw blade is provided with a first limiting part. When folding, the saw blade is rotated and stored in the containing cavity, and the first handle part and the second handle part are rotated to close the containing cavity. The folding is convenient, and the saw blade can be effectively covered to improve safety. When unfolding, the saw blade is rotated to the outside of the handle, and the first handle part and the second handle part are rotated to close. The limiting structure on the second handle part can cooperate with the first limiting part to limit the rotation of the saw blade, improve the stability of the saw during use, and facilitate the use of the saw.
[0004] For example, the Chinese utility model patent with the patent application number CN202321073052.2 discloses a foldable saw, which comprises a handle, a saw blade, and a blocking pin.

DETAILED DESCRIPTION
[0018] The specific embodiments of the utility model are further explained in combination with the drawings. It needs to be explained here that the explanation of these embodiments is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.
[0019] In the description of the utility model, it needs to be understood that the orientation or position relation indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" are based on the orientation or position relation shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as the limitation to the utility model that the indicated device or element must have the specific orientation, be constructed and operated in the specific orientation.
[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0021] like Figs. 1-2 As shown, the easily lockable saw includes a handle 1 and a blade 2 rotatably connected to the handle 1. The blade 2 has several serrations. A blade sleeve 3 is fitted onto the outside of the handle 1, and a locking sleeve 4 is fitted onto the outside of the blade sleeve 3. The blade sleeve 3 is fixedly connected to the handle 1 via a pin 5. A limiting screw 6 is installed on the handle 1. The locking sleeve 4 has a limiting through hole that matches the limiting screw 6. The end of the limiting screw 6 protrudes from the limiting through hole 7. The locking sleeve 4 is rotatably fitted onto the outside of the blade sleeve 3. It can be understood that the blade 2, blade sleeve 3, locking sleeve 4, pin 5, and limiting screw 6 can all be made of stainless steel, etc.
[0022] Specifically, the outer side of the blade 2 is provided with a first pin through hole 8 that matches the pin 5, the outer side of the handle 1 is provided with a second pin through hole 9 that matches the pin 5, and the outer side of the blade sleeve 3 is provided with a third pin through hole 10 that matches the pin 5. The end of the pin 5 passes through the first pin through hole 8, the second pin through hole 9, and the third pin through hole 10. The inner side of the locking sleeve 4 is provided with an inner groove 11 that matches the end of the pin 5. The inner groove 11 is located outside the end of the pin 5 to prevent the locking sleeve 4 from rubbing against the pin 5 during rotation. The outer side of the blade sleeve 3 is provided with a limiting screw through hole 12 that matches the limiting screw 6. The limiting screw 6 passes through the limiting screw through hole 12 and is fixedly connected to the handle 1.
