Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4A fixed bracket for laser engraving shown in the figure includes a workbench 1, a transmission cavity is opened in the workbench 1, two sliding holes are opened on the top of the transmission cavity, two sliding blocks 2 are slidably installed in the two sliding holes through sliding components, a rectangular plate 7 is installed on the top of the two matching sliding blocks 2, square holes are opened on the sides of the two rectangular plates 7, square sliding columns 8 are slidably installed in the two square holes, limiting plates 9 are fixedly installed on the sides of the two square sliding columns 8, first clamping plates 10 are fixedly installed on the other sides of the two square sliding columns 8, reset components are provided on the sides of the two first clamping plates 10, two side holes are opened on the sides of the two rectangular plates 7, second clamping plates 12 are slidably installed in the four side holes, and the four second clamping plates 12 are connected to the two limiting plates 9 by connecting components.

[0023] With the help of the above structure, when in use, the workpiece to be engraved is placed on the top of the workbench 1, and then the four sliders 2 are driven to move synchronously through the sliding assembly, so that the two rectangular plates 7, the two square slide columns 8, and the two first clamps 10 move toward each other synchronously. When the two first clamps 10 are in contact with the workpiece to be engraved, the two square slide columns 8 make the two first clamps 10 remain relatively still, and the two rectangular plates 7 move toward each other. When the two rectangular plates 7 continue to move, the two second clamps 12 are driven to move toward each other synchronously under the action of the two connecting components, and the workpiece to be engraved is pushed and clamped synchronously by both sides. When one side is clamped and fixed, it will drive the workpiece to be engraved to move horizontally synchronously until the other side realizes the clamping and fixing function, realizes the center alignment function, and the clamping and fixing operation is simple and practical.

[0024] like Figure 3 As shown, the sliding assembly includes two bidirectional screw rods 3, both ends of which are rotatably mounted on the opposite inner walls of the transmission chamber, and the two bidirectional screw rods 3 are connected by a transmission unit. Four sliders 2 are respectively threadedly mounted on the two bidirectional screw rods 3. The advantage of such an arrangement is that, through the arrangement of the two bidirectional screw rods 3, the function of driving multiple sliders 2 to move synchronously can be realized, thereby clamping and fixing the engraved workpiece.

[0025] like Figure 3 As shown, the transmission unit includes two sprockets 4, which are respectively fixedly sleeved on two bidirectional screw rods 3, and a chain 5 is installed on the two sprockets 4 in meshing relationship. A driving motor 6 is fixedly installed on the side of the workbench 1, and the output shaft of the driving motor 6 is connected to the end of one of the bidirectional screw rods 3. The advantage of such an arrangement is that the function of driving the two bidirectional screw rods 3 to rotate synchronously can be achieved through the arrangement of the two sprockets 4 and the chain 5.

[0026] like Figure 3As shown, the reset assembly includes a reset spring 11, one end of the reset spring 11 is fixedly mounted on the side of the first clamping plate 10, and the other end of the reset spring 11 is fixedly mounted on the side of the rectangular plate 7. The advantage of this arrangement is that, through the arrangement of the reset spring 11, when the squeezing function of the first clamping plate 10 is released, the reset function can be achieved under the elastic action of the reset spring 11.

[0027] like Figure 3 As shown, the connecting assembly includes a connecting rod 13, one end of the connecting rod 13 is rotatably mounted on the side of the second clamping plate 12, and the other end of the connecting rod 13 is rotatably mounted on the side of the limit plate 9. The advantage of such an arrangement is that, through the arrangement of the connecting rod 13, when the limit plate 9 is fixed and the rectangular plate 7 continues to move, the two second side plates 12 can be driven to move toward each other synchronously under the action of the two connecting rods 3.

[0028] like Figure 3 As shown, the sides of the first clamping plate 10 and the second clamping plate 12 are both provided with protection pads 14. The advantage of such a configuration is that the two protection pads 14 can protect the sculpture during the clamping process to prevent damage during the clamping process.

[0029] like Figure 4 As shown, a purification box 15 is fixedly installed on the side of the workbench 1, and a plurality of air inlet holes 16 are evenly opened on the inner wall of one side of the purification box 15, and an air outlet pipe 17 is arranged on the inner wall of the other side of the purification box 15, and an air pump 18 is arranged on the air outlet pipe 17. A mounting groove is arranged on the top of the purification box 15, and an activated carbon filter plate 19 is slidably installed in the mounting groove, and a pull ring 20 is arranged on the top of the activated carbon filter plate 19. The advantage of such an arrangement is that, through the arrangement of the purification box 15, the air pump 18 and the activated carbon filter plate 19, the smoke and gas generated during engraving can be absorbed to prevent the irritating gas from affecting the staff.

[0030] The practical working principle of the present invention is as follows: when in use, first place the workpiece to be engraved on the top of the workbench 1, then start the driving motor 6 to drive one of the two-way screw rods 3 to rotate, and then drive the two two-way screw rods 3 to rotate synchronously under the meshing action of the two sprockets 4 and the chain 5, thereby driving the four sliders 2 to move synchronously, and then make the two rectangular plates 7, the two square slide columns 8, and the two first clamping plates 10 move toward each other synchronously. When the two first clamping plates 10 are in contact with the workpiece to be engraved, the two square slide columns 8 make the two first clamping plates 10 remain relatively still, and make the two rectangular plates 7 move toward each other. When the two rectangular plates 7 continue to move, the two second clamping plates 12 are driven to move toward each other synchronously under the action of the two connecting rods 13, and the workpiece to be engraved is pushed and clamped synchronously by both sides. When one side is clamped and fixed, it will drive the workpiece to be engraved to move horizontally synchronously until the other side realizes the clamping and fixing function, realizes the center alignment function, and the clamping and fixing operation is simple and practical.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
