[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1-2As shown, the utility model provides a technical solution for a telescopic hand saw: it includes a shell 1, the shape of the shell 1 is arc-shaped, a long groove 2 is opened on one side of the shell 1 along the length direction of the shell 1, the long groove 2 is a through groove, a saw blade 3 is slidably connected in the long groove 2, the saw blade 3 slides along the length direction of the long groove 2, and saw teeth are arranged on the bottom surface of the saw blade 3. When the saw blade 3 is not in use, the saw blade 3 is moved into the long groove 2. On the one hand, the situation that the saw blade 3 hurts the user is reduced, and on the other hand, it is convenient to carry, and the user can adjust the length of the saw blade 3 at any time according to the actual situation.

[0022] In this embodiment, an arc-shaped groove 4 is opened on one side of the shell 1 along the length direction of the shell 1, and the arc-shaped groove is connected with the long groove 2. A bolt 5 is slidably connected in the arc-shaped groove 4 along the length direction of the arc-shaped groove 4. At the same time, a threaded hole is opened on one side of the saw blade 3. The bolt 5 is threadedly connected to the threaded hole and one end extends out of the arc-shaped groove 4. When moving the saw blade 3, the user holds the bolt 5 in his hand, which is convenient for the user to pull the saw blade 3.

[0023] In this embodiment, in order to facilitate the user to hold the bolt 5, a grip block 6 is installed at the outer end of the bolt 5, and the grip block 6 is cylindrical in shape.

[0024] In this embodiment, a hook 7 is installed on one side of the saw blade 3. When the hand saw is not in use, the hook 7 is hung on the user's waist or at a pre-set position to facilitate the user's carrying and placement of the hand saw.

[0025] In this embodiment, a hanging ring 8 engaged with the hook 7 is hinged on one side of the saw blade 3. When the hand saw is hung, the hanging ring 8 increases the connection strength between the hook 7 and the placement position, reducing the possibility of the hand saw falling.

[0026] In this embodiment, a hand grip shell 9 is inserted into the outer shell 1, friction lines are arranged on the top surface of the hand grip shell 9, and a limit block 10 is integrally formed and installed on the top surface of the hand grip shell 9. The hand grip shell 9 is convenient for the user to hold the hand saw and makes the hand saw more beautiful.

[0027] In this embodiment, a weight-reducing hole 11 is provided on one side of the housing 1 and is located below the long groove 2. The weight-reducing hole 11 reduces the weight of the entire hand saw, making it convenient for outdoor use and carrying.
