Embodiment 1

[0014] As shown in Figure 1, a hand saw that can prevent skin abrasion, said hand saw includes a saw blade 1 and a handle 3, the saw blade 1 and the handle 3 are connected by two screws 5, and one side of the saw blade 1 is provided with a serrated edge 2, The handle 3 is provided with a handle hole 4, and the outside of the handle hole 4 of the handle 3 has a through hole 6 with the same diameter arranged to form a rhombus. The through holes 6 are arranged to form a certain angle, which can reduce the heat between the handle and the hand. friction while saving material.

Embodiment 2

[0016] As shown in Figure 2, it is a schematic diagram of the structure of the hand saw embodiment 2. On the outside of the handle hole 4 of the handle 3, there are through holes 6 with the same diameter arranged to form a parallelogram. The through holes 6 are arranged in a straight line, and they are in the same plane. Arrangement allows for maximum cooling area during operation.

Embodiment 3

[0018] As shown in Figure 3, it is a schematic diagram of the structure of the hand saw embodiment 3. On the outside of the handle hole 4 of the handle 3, there are through holes 6 with the same diameter and arranged in an arc fan shape. The through holes 6 are arranged in an arc shape. On the plane, this arrangement is most in line with manual operation habits, and can adjust the shape of the handle in the palm and have a good heat dissipation effect, and can improve the positioning of the handle 3 .
