[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the embodiments of this application, please refer to Figure 1-2 As shown, the handle fixing structure of the cutting machine mainly includes: a main body 1 and a cutting assembly 2 installed on the main body 1 and at least rotatable, the cutting assembly 2 includes a housing 21, a motor 22 and a saw blade 23, the saw blade 23 is installed in the housing 21 and driven by the motor 22, and the housing 21 is provided with a handle 3, as shown in FIG. Figure 2 As shown, from a top view when the cutting machine is working, the handle 3 is placed directly above the saw blade 23 .

[0023] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0024] like Figure 3 As shown, the handle 3 includes a grip 31 and a handle 32. The grip 31 is extendedly arranged in the length direction of the shell 21, and the handle 32 is arranged at the outer end of the shell 21 for holding and pushing the cutting assembly 2 or moving the main body 1.

[0025] Specifically, a connecting support portion is provided at the outer end of the housing 21, and one end of the handle 32 is connected to the connecting support portion through a fastener.

[0026] Furthermore, a switch 311 is provided in the handle 32 for controlling the on and off of the motor 22 .

[0027] Furthermore, the housing 21 is formed with a covering area for covering at least a portion of the saw blade 23 and wrapping a portion of the saw blade 23 to prevent accidental contact with the saw blade 23 and improve safety.

[0028] Furthermore, a shield mechanism 4 is also provided in the shell 21. The shield mechanism 4 can be unfolded relative to the shell 21 to increase the coverage area of ​​the saw blade 23, so as to block the debris or dust generated during the cutting process. The shield mechanism 4 can automatically rotate and retract inwardly under the obstruction of the cutting material, so as to avoid blocking the normal cutting operation.

[0029] like Figure 4 As shown, the cutting assembly 2 is installed on the main body 1 through an adjusting mechanism 5, and the main body 1 includes a support arm 11. The adjusting mechanism 5 includes a slide rod 51, a sliding seat 52, and a hinge 53. The first end of the slide rod 51 is fixedly set on the support arm 11 and extends toward the saw blade 23 frame; the saw blade 23 frame is hingedly set on the sliding seat 52, and the sliding seat 52 is slidably mounted on the slide rod 51. The hinge 53 is installed between the sliding seat 52 and the support arm 11. The adjusting mechanism 5 is used to adjust the lateral movement of the cutting assembly 2 to achieve continuous mobile cutting.
