When the front transparent panel 121 opens the opening 10b, it allows the object to be engraved to pass through the opening 10b. When the front transparent panel 121 closes the opening 10b, it seals the receiving space 10a, thereby separating the receiving space 10a from the external environment of the laser engraving machine 100. While the user can view the laser module 40 in the receiving space 10a, external foreign objects are prevented from directly contacting the laser module 40, thus achieving external protection for the laser module 40.

[0056] Please refer to the attached document. Figure 3 In this embodiment, when the front transparent panel 121 is rotatably connected to the support portion 13, the front transparent panel 121 is connected to the support portion 13 via a pivot and rotates along the axis of the pivot to swing relative to the reinforcing beam 131; the front transparent panel 121 is provided with a rotating hole, and the rotating hole and the pivot are fitted with a clearance, so that the front transparent panel 121 can rotate relative to the support portion 13 through the rotating hole and the pivot.

[0057] One end of the front transparent panel 121 is connected to a bending member 14. The bent part of the bending member 14 overlaps the bottom of the reinforcing beam 131 to maintain the front transparent panel 121 in a closed state relative to the opening 10b. The overlap between the bending member 14 and the reinforcing beam 131 makes the connection between the front transparent panel 121 and the support part 13 more secure, improves the overall strength of the housing 10, and prevents external foreign objects from directly impacting the laser module 40.

[0058] Please refer to the attached document. Figures 1-4In this embodiment, the front transparent panel 121 is arranged in an L-shape. The front transparent panel 121 is provided with a first protrusion 1211, and the first protrusion 1211 is connected to a magnetic component 1212.
