[0021] The clamping assembly 5 includes a rotating shaft 51, which is rotatably mounted in the mounting plate 4. A gear 52 is fixedly connected to the rotating shaft 51, and a rack 53 is slidably connected to the mounting plate 4. The rack 53 is matched with the gear 52, and one end of the rack 53 is fixedly connected to the pressure plate 54 on the outside of the mounting plate 4. The two ends of the rotating shaft 51 are respectively fixedly connected to the gear 2 55 and the gear 3 56. The mounting plate 4 is slidably connected to the rack 2 57 and the rack 3 58. The rack 2 57 is matched with the gear 2 55. The rack 3 58 is meshed with the gear 3 56, and two mounting boxes 6 are symmetrically slidably installed on the mounting plate 4. The two mounting boxes 6 are fixedly connected to the rack 2 57 and the rack 3 58 respectively. The opposite ends of the two mounting boxes 6 are fixedly connected with a clamping plate 59. The blank is placed on the pressing plate 54. The pressing plate 54 drives the rack 1 53 to slide downward. The rack 1 53 drives the rotating shaft 1 51 to rotate by cooperating with the gear 1 52. The rotating shaft 1 51 drives the gear 2 55 and the gear 3 56 to rotate at the same time. Figure 3 As shown, the gear 2 55 cooperates with the rack 2 57 to drive the installation box 6 on the left to move, and the gear 3 56 cooperates with the rack 3 58 to drive the installation box 6 on the right to move, so that the two installation boxes 6 move toward or oppositely, so that the two installation boxes 6 respectively drive the two clamping plates 59 to move to clamp and fix the blank;

[0022] The two installation boxes 6 are both equipped with fixing components 7 .

[0023] The fixing assembly 7 includes a slide plate 71, a mounting groove 79 is opened in the mounting box 6, and the slide plate 71 is slidably installed in the mounting groove 79. A spring rod 72 is fixedly connected between the slide plate 71 and the inner wall of the mounting groove 79. The end of the slide plate 71 located on the outside of the mounting box 6 is fixedly connected to the cover plate 73, and the lower end of the slide plate 71 is fixedly connected to the touch rod 74. A slide plate 2 75 is slidably installed on the mounting groove 79, and the end of the slide plate 2 75 located on the outside of the mounting box 6 is fixedly connected to the baffle 76. A connecting rod 77 is slidably installed on the side wall of the mounting box 6, and the end of the connecting rod 77 located on the outside of the mounting box 6 is fixedly connected to the baffle 76, and the end of the connecting rod 77 located on the inside of the mounting box 6 is fixedly connected to the limit plate 78.

[0027] A plurality of sets of fixing bolts 14 are fixedly mounted on the base plate 1 , and the plurality of fixing bolts 14 can facilitate the fixed installation of the base plate 1 .

[0028] In the present invention, the blank is first placed on the anti-slip mat 10, the pressing plate 54 drives the rack 1 53 to slide downward, the rack 1 53 drives the shaft 1 51 to rotate by cooperating with the gear 1 52, and the shaft 1 51 drives the gear 2 55 and the gear 3 56 to rotate simultaneously. Figure 3As shown, gear 2 55 drives the installation box 6 on the left to move by cooperating with rack 2 57, and gear 3 56 drives the installation box 6 on the right to move by cooperating with rack 3 58, so that the two installation boxes 6 move toward or oppositely, so that the two installation boxes 6 respectively drive the two clamping plates 59 to move to clamp and fix the blank; during the operation of the clamping assembly 5, the baffle 76 contacts the blank and slides toward the inside of the installation groove 79 by cooperating with the slide plate 2 75. The baffle 76 drives the limit plate 78 to move through the connecting rod 77, so that the limit plate 78 cancels the limit on the touch rod 74. At this time, under the elastic force of the spring rod 72, the slide plate 1 71 drives the cover plate 73 to move downward, so that the cover plate 73 clamps and fixes the upper side of the edge of the blank, thereby further clamping and fixing the blank and improving the clamping and fixing stability of the device.
