[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a portable laser marking device, including a device body 1 and a scanning galvanometer 2, and the device body 1 and the scanning galvanometer 2 are used together. The device body 1 is provided with a shielding mechanism 3 that works with the scanning galvanometer 2, and the bottom of the device body 1 is provided with a moving mechanism 4 that works together.

[0020] The shielding mechanism 3 includes a mounting ring 31, which is fixedly mounted on the device body 1. A sleeve 32 is fixedly fitted on the outer side of the mounting ring 31. One end of the sleeve 32 has a through hole 312, and the mounting ring 31 is fixedly inserted into the through hole 312. The through hole 312 ensures a stable connection between the mounting ring 31 and the sleeve 32. The sleeve 32 is fixedly fitted on the outer side of the scanning galvanometer 2, and a through groove 33 for use with the scanning galvanometer 2 is opened through the sleeve 32. One end of the sleeve 32 has a through hole 34, and a rotating rod 35 is rotatably inserted into the through hole 34. A wristband 310 is fixedly fitted to the end of the rotating rod 35. The outer wall of the 0 has an array of grooves 311. The grooves 311 are designed to increase friction and facilitate operation. A rotating cylinder 36 is fixedly sleeved on the outer side of the rotating rod 35, and the rotating cylinder 36 is rotatably sleeved on the sleeve 32. A through groove 37 is opened through the rotating cylinder 36 to cooperate with the through groove 33. The inner diameter of the through groove 37 is larger than the inner diameter of the through groove 33, thus ensuring the normal use of the scanning galvanometer 2 when the through groove 33 and the through groove 37 are docked. A spring 38 is fixedly installed on one side of the sleeve 32, and a retaining ring 39 is fixedly connected to the end of the spring 38. The spring 38 is in a compressed state, and the retaining ring 39 slides against the inner wall of the rotating cylinder 36.

[0021] By adopting the above technical solution, when laser marking is required, the wristband 310 needs to be held and rotated, which can drive the rotating rod 35 to rotate, which in turn can drive the rotating cylinder 36 to rotate, and further drive the slot 2 37 to rotate. During this period, the side of the abutment ring 39 away from the spring 38 is always in close contact with the inner wall of the rotating cylinder 36 under the elastic force of the spring 38. When the wristband 310 is rotated 180 degrees, the rotation of the wristband 310 is stopped. At this time, the slot 2 37 will be connected with the slot 1 33, so that the scanning galvanometer 2 is exposed and can operate normally. When the laser marking operation is completed, the slot 2 37 can be reset.

[0022] The assistive mechanism 4 includes a rotating shaft 41, which is rotatably inserted at the four corners of the bottom end of the device body 1. A rotating plate 42 is fixedly sleeved on the rotating shaft 41. Symmetrically arranged rotating holes 13 are opened through both sides of the bottom end of the device body 1, and the rotating shaft 41 is rotatably inserted into the adjacent rotating holes 13. The rotating holes 13 provide a guarantee for the stable rotation of the rotating shaft 41. A roller 43 is rotatably inserted on the rotating plate 42, and a spring 44 is fixedly installed on one side of the rotating plate 42. A slip ring 45 is fixedly connected to the end of the spring 44, and the slip ring 45 slides... The device body 1 is mounted on the rotating shaft 41. A plug 46 is fixedly installed on one side of the slip ring 45. Symmetrically distributed insertion holes 11 are opened through both sides of the bottom end of the device body 1. The plug 46 can be slidably inserted into the insertion hole 11. A push post 47 is fixedly installed at one end of the plug 46. The push post 47 can be slidably locked on the device body 1. An arc groove 12 is opened through between adjacent insertion holes 11. The push post 47 can be slidably locked in the arc groove 12. The cooperation between the push post 47 and the arc groove 12 provides convenience for the easy pushing of the plug 46.

[0023] By adopting the above technical solution, when the laser marking device needs to be moved, the four push pins 47 need to be pressed in sequence, which can drive the corresponding insertion pin 46 to move, and then drive the corresponding slip ring 45 to move and squeeze the corresponding spring 44. When the insertion pin 46 is separated from the corresponding insertion hole 11, the corresponding roller 43 is rotated 90 degrees and the corresponding push pin 47 is released. At this time, the corresponding spring 44 will drive the corresponding insertion pin 46 to reset and insert into another corresponding insertion hole 11. Then, the corresponding laser marking device can be easily moved to a suitable position with the help of the four rollers 43. After moving to the suitable position, the four rollers 43 can be reversed and reset to fix it.

[0024] Working principle: When using the laser marking operation, the wristband 310 needs to be held and rotated, which will drive the rotating rod 35 to rotate, which in turn will drive the rotating cylinder 36 to rotate, and further drive the slot 2 37 to rotate. During this period, the side of the abutment ring 39 away from the spring 38 is always in close contact with the inner wall of the rotating cylinder 36 under the elastic force of the spring 38. When the wristband 310 is rotated 180 degrees, the rotation of the wristband 310 is stopped. At this time, the slot 2 37 will be connected with the slot 1 33, so that the scanning galvanometer 2 is exposed and can operate normally. When the laser marking operation is finished, the slot 2 37 can be reset.

[0025] In addition, when the laser marking device needs to be moved, the four push pins 47 need to be pressed in sequence, which can drive the corresponding insertion pin 46 to move, and then drive the corresponding slip ring 45 to move and squeeze the corresponding spring 44. When the insertion pin 46 separates from the corresponding insertion hole 11, the corresponding roller 43 is rotated 90 degrees and the corresponding push pin 47 is released. At this time, the corresponding spring 44 will drive the corresponding insertion pin 46 to reset and insert into another corresponding insertion hole 11. Then, the corresponding laser marking device can be easily moved to a suitable position with the help of the four rollers 43. After moving to the suitable position, the four rollers 43 can be reversed and reset to fix it.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
