The inner wall of the fixture 10 is provided with a clearance groove 20. The inner wall of the clearance groove 20 is fixedly connected with a third spring 21. The other end of the third spring 21 is fixedly connected to the first positioning plate 22. The front surface of the first positioning plate 22 is fixedly connected with a displacement rod 23. The front end of the displacement rod 23 slides through the front surface of the fixture 10. The interior of the fixture 10 is provided with a second cavity 24.

[0027] Working principle: When the jig 10 needs to be quickly replaced to replace the marked product, the button 17 is pressed by the side of the two palms. When the button 17 is pressed, the horizontal plate 16 is moved synchronously. When the horizontal plate 16 moves, it will simultaneously compress the second spring 15 and drive the unlocking sleeve 18 to move. After the unlocking sleeve 18 moves, it contacts the upper surface of the block 8, and uses the inclined surface of the upper side of the block 8 to make the block 8 move toward the inside of the cavity 6, thereby making the block 8 disengage from the annular groove 13. At this time, the palm of your hand contacts the jig 10 and lifts the jig 10 together with the mounting plate 9 for quick disassembly. When installing, align the vertical rod 12 with the locking groove 5 and insert it. After insertion, the vertical rod 12 again uses the inclined surface of the block 8 to squeeze the block 8 to move and compress the spring 7. When the annular groove 13 is aligned with the block 8, the spring 7 is used. The elastic force pushes the block 8 into the inside of the annular groove 13, and then locks the vertical rod 12 with the help of the plane of the lower surface of the block 8. When the product is placed for marking, the displacement rod 23 is first pulled outward. When the displacement rod 23 moves, it will synchronously drive the first positioning plate 22 to move, and when the first positioning plate 22 moves, it will also synchronously compress the third spring 21, and when the displacement rod 23 moves, the second positioning plate 29 can be synchronously pulled to move with the help of the cable 28. When the second positioning plate 29 moves, the fourth spring 32 will be synchronously compressed with the help of the sliding rod 30. At this time, the product to be marked is placed inside the fixture 10, and then the displacement rod 23 is released. Under the action of the third spring 21 and the fourth spring 32, the second positioning plate 29 and the first positioning plate 22 move, thereby positioning and clamping the marked product.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
