Furthermore, to provide the public with a better understanding of this application, certain specific details are described in detail below. However, this application can be fully understood by those skilled in the art even without these detailed descriptions.

[0012] See Figure 1 A general-purpose positioning and marking fixture includes a support plate 1 and a marking assembly. A first left-right helical trapezoidal screw assembly is disposed below the support plate 1, and a second left-right helical trapezoidal screw assembly is disposed below the first left-right helical trapezoidal screw assembly. The first left-right helical trapezoidal screw assembly includes a first screw 2, a first handwheel 5 connected to the first screw 2, and a left pressure plate 3 and a right pressure plate 4 respectively disposed on the left and right sides of the support plate 1. The first screw 2 is threadedly connected to a first left-hand nut and a first right-hand nut. The left pressure plate 3 and the right pressure plate 4 are respectively mounted on the first left-hand nut and the first right-hand nut. The second left-right helical trapezoidal screw assembly includes a second screw 6, a second handwheel 7 connected to the second screw 6, and a front pressure plate 8 and a rear pressure plate 9 respectively disposed on the front and rear sides of the support plate 1. The second screw 6 is threadedly connected to a second left-hand nut and a second right-hand nut. The front pressure plate 8 and the rear pressure plate 9 are respectively mounted on the second left-hand nut and the second right-hand nut.

[0013] The marking assembly includes a base plate 10, two guide shafts 11, a mounting plate 12, a connecting frame 13, a guide rail 15, a manual slide 16, and a stamp mounting plate 17. The bottoms of the two guide shafts 11 are connected to both ends of the base plate 10, and the tops of the two guide shafts 11 pass through both ends of the mounting plate 12. The connecting block 12 is connected to the guide shafts via linear bearings. Springs 14 are fitted on both guide shafts 11. The top of the springs 14 is connected to the mounting plate 12, and the bottom of the springs 14 is connected to the base plate 10. The guide rail 15 is mounted on the mounting plate 12. The manual slide 16 is slidably mounted on the guide rail 15. The connecting frame 13 is mounted on the manual slide 16. The connecting frame 13 is provided with a sliding groove, and the stamp mounting plate 17 is slidably mounted in the sliding groove.

[0014] The left pressure plate 3 is connected to the first left-hand nut via a left moving block, the right pressure plate 4 is connected to the first right-hand nut via a right moving block, the front pressure plate 8 is connected to the second left-hand nut via a front moving block, and the rear pressure plate 9 is connected to the second right-hand nut via a rear moving block.

[0016] In use, the stamp is mounted on the stamp mounting plate, and the product to be stamped is placed on the tray. The first and second handwheels are rotated to position the left, right, front, and rear pressure plates on the product. Then, the manual slide and stamp mounting plate are moved so that the stamp is directly above the desired stamping position. The plunger is pressed down, causing the stamp to move downwards and stamp the product. After stamping, the stamp returns to its position above the product due to the spring force. The mounting plate has a plunger mounting bracket, allowing the plunger to be placed in the bracket after use.
