The multiple guide rollers 5221 roll relative to the inner wall of the bracket 521 so that the third movable seat 522 can move relative to the bracket 521 by means of the multiple guide rollers 5221, which improves the smoothness of the movement of the third movable seat 522 relative to the bracket 521 and at the same time avoids the third movable seat 522 from shifting its position during the movement.

[0077] Please refer to the attached document. Figure 8 The laser engraving module 42 is vertically and vertically connected to the second transfer module 52 and can be locked to the second transfer module 52 to adjust the position of the laser engraving module 42 relative to the second transfer module 52. This facilitates the height adjustment of the laser engraving module 42, enabling the laser engraving module 42 to move along the Z-axis, ensuring that the laser engraving module 42 can move in the X, Y, and Z-axis directions, further enriching the movement effect of the laser engraving module 42.

[0078] Please refer to the attached document. Figure 8A track 525 is provided between the third movable seat 522 and the outer shell 41. The track 525 is arranged in the vertical direction and is connected to the third movable seat 522. The outer shell 41 is movably connected to the track 525 so as to adjust the height position of the outer shell 41 relative to the track 525.

[0079] Please refer to the attached document. Figures 6-7 The laser engraving assembly 40 also includes a heat sink 43, which is disposed inside the housing 41. The laser engraving module 42 is installed on the heat sink 43 and exchanges heat with the heat sink 43 so that the heat generated by the laser engraving module 42 during operation can be conducted to the heat sink 43 to achieve the heat dissipation effect of the laser engraving module 42, reduce the temperature of the laser engraving module 42, and avoid the laser engraving module 42 from overheating.

[0080] Please refer to the attached document. Figures 6-7 The heat sink 43 and the outer casing 41 form a receiving groove 41a. The laser engraving assembly 40 also includes a focusing element 44, which is telescopically connected to the outer casing 41 and can retract or extend relative to the receiving groove 41a. This allows for adjustment of the position of the focusing element 44 relative to the outer casing 41, enabling multiple position adjustments and focusing at different heights. This avoids situations where the focusing element 44 cannot be adjusted to multiple positions relative to the outer casing 41. The focusing element 44 is locked to the outer casing 41 to maintain its position relative to the outer casing 41, ensuring positional accuracy and improving focusing precision. This also prevents accidental position adjustments of the focusing element 44 relative to the outer casing 41. Optionally, the bottom of the focusing element 44 can be a flat end, a beveled end, or a sharp end.

[0081] Please refer to the attached document. Figures 6-7 The outer casing 41 is provided with a through hole 41b, which connects to the receiving groove 41a. The laser engraving assembly 40 also includes an operating member 45, which passes through the through hole 41b to extend into the receiving groove 41a. The operating member 45 is connected to the focusing member 44 and is used for user operation or movement. This allows the user to operate or move the operating member 45 to extend or retract the focusing member 44, thereby facilitating the extension and retraction of the focusing member 44 relative to the receiving groove 41a under external force and improving the ease of extension and retraction of the focusing member 44. Optionally, the through hole 41b is an elongated hole.

[0082] Please refer to the attached document. Figures 6-7The operating component 45 is provided with an operating part 451 and a connecting part 452, with the connecting part 452 connected to the operating part 451. The operating part 451 is exposed on the outside of the housing 41 and is used for operation or movement by the user, so that the user can operate or move the operating part 451 in the external environment, thereby facilitating the user to operate or move the operating component 45 through the operating part 451. The connecting part 452 moves with the operation part 451 and is provided with a through hole 41b, so that the connecting part 452 extends into the receiving groove 41a through the hole 41b. The connecting part 452 is connected to the focusing component 44, so that the operating part 451 is connected to the focusing component 44 through the connecting part 452, thereby facilitating the extension and retraction of the focusing component 44 as the operating part 451 moves.

[0083] Please refer to the attached document. Figures 1-5 The laser engraving machine 100 also includes a display module 60, which includes a rotating component 61 and a display screen 62. The display screen 62 is used to display images. The rotating component 61 is located between the housing 10 and the display screen 62. The display screen 62 is connected to the housing 10 through the rotating component 61. The display screen 62 is swayably connected to the housing 10 to adjust the position of the display screen 62 relative to the housing 10, thereby facilitating the adjustment of the angle position of the display screen 62. The display screen 62 can be housed in the housing 10 or tilted relative to the housing 10, making full use of the housing 10's housing space relative to the display screen 62. This ensures that the display screen 62 can be housed in the housing 10 or tilted relative to the housing 10, allowing the user to view the display screen 62 in a tilted state. This avoids the situation where the display module 60 can only be housed in the housing 10 and cannot be tilted, thus combining the housing function and the tilting function.

[0084] Please refer to the attached document. Figures 1-5 The housing 10 has a display screen slot 10c; a rotating member 61 is connected to the display screen 62 and the housing 10, and is located within the display screen slot 10c; the display screen 62 swings relative to the housing 10 to adjust its position relative to the housing 10, and is accommodated in or detached from the display screen slot 10c. This fully utilizes the accommodating space of the display screen slot 10c relative to the display screen 62. When the display screen 62 is accommodated in the display screen slot 10c, it is able to be accommodated within the housing 10, thus facilitating full utilization of the accommodating space of the housing 10 relative to the display screen 62. When the display screen 62 is detached from the display screen slot 10c, it allows the display screen 62 to tilt relative to the housing 10, ensuring that the display screen 62 can be viewed by the user in a tilted state, avoiding the situation where the display module 60 can only be accommodated within the housing 10 without tilting, thus combining both accommodating and tilting functions. Optionally, the rotating member 61 is an elliptical rotating shaft.

[0085] Please refer to the attached document. Figures 1-5The housing 10 is provided with a hand-holding groove 10d, which is located on the lower side of the display screen groove 10c and is connected to the display screen groove 10c. When the display screen 62 is housed in the display screen groove 10c, the hand-holding groove 10d exposes the bottom of the display screen 62 and allows the user's hand to enter, so that the user's hand can pass through the hand-holding groove 10d and extend to the display screen groove 10c. This makes it easy for the user's hand in the display screen groove 10c to swing the display screen 62, so that the display screen 62 can swing relative to the connecting seat under the action of external force, ensuring that the display screen 62 is tilted for the user to view.
