[0028] Further, as Figure 1 , Figure 2 , Figure 4 shown, the middle part of the two side walls of clamping table 200 is provided with support shaft 210;The top of rack 100 is respectively provided with first optical axis support seat 410 and second optical axis support seat 420, and clamping table 200 is rotatably arranged between first optical axis support seat 410 and second optical axis support seat 420 by support shaft 210;First optical axis support seat is fixed to clamping part by bolt, and the required clamping force is maintained, and the clamping force of clamping part is adjusted by handle of second optical axis support seat;Two different locking modes of optical axis support seat are used to rotatably support and lock clamping table, the main clamping force is provided by first optical axis support seat, and the auxiliary clamping force is provided by second optical axis support seat, so that the clamping force can be changed by adjusting handle during subsequent use, the tightness is adjusted, and the placement position of clamping table is adjusted.

[0029] Further, as Figure 1 , Figure 4As shown, the first optical axis support seat 410 is provided with a support frame 500 on the side away from the center of the rack 100. The support frame is fixedly installed on the rack by bolts, and the support frame 500 is located outside the end of the support shaft 410. A plurality of first jacks 510 are arranged in a circular array around the axis of the support shaft on the support frame 500. A second jack 211 is provided on the end face of the support shaft 210 close to the support frame 500. When the clamping table is rotated to a specified angle position, the second jack corresponds to the position of one of the first jacks. The clamping table can be locked by inserting a plug into the first jack and the second jack, maintaining the angle. The plug includes but is not limited to a column, a long screw, a screwdriver, and other components with sufficient strength, which can be inserted into the first jack and the second jack to limit the clamping table from rotating. The structure design can achieve the effect of secondary locking of the clamping table, making it unable to rotate, especially for some heavy printing substrates, further expanding the applicability. It should be noted that the design and cooperation of the hole positions at least need to meet the locking and staying of the clamping table at 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315° positions, meeting the more common angle requirements.

[0030] Further, as shown in Figure 4 The clamping table 200 includes a support plate 220, and two support shafts 210 are fixedly arranged on the middle portions of the opposite two side walls of the support plate 220.

The stop block 241 is installed on the supporting plate 220 by a bolt, and the third supporting bolt 242 is threadedly connected to the stop block 241 and penetrates the blocking surface of the stop block. By adjusting the third supporting bolt outwardly extended as the blocking limiting part, the limiting range can be adjusted according to the printing substrate of different sizes, the limiting range is changed, and the application range is expanded.

[0035] Further, the number of the stop block assemblies is four, which are symmetrically distributed on the remaining two sides of the supporting plate in two groups.
