[0007] Optionally, the mounting base is connected to a snap-fit ​​block around its outer perimeter. One end of the snap-fit ​​block extends into the snap-fit ​​groove. A magnetic block is connected to the middle of one end of the snap-fit ​​block. Slide rods are connected to both sides of one end of the snap-fit ​​block.

[0027] Example

[0028] like Figures 1-3 As shown, the present invention proposes a quick-change fixture structure for chip testing, including a base 1. The upper end of the base 1 is provided with insertion holes 2 around its four sides. A fixture body 3 is snapped onto the upper end of the base 1. The upper end of the fixture body 3 is provided with a placement groove for placing and fixing the chip. The lower end of the fixture body 3 is provided with a groove 4. The inner side of the groove 4 is provided with a snap-fit ​​groove 5. Insertion rods 6 are connected around the lower end of the fixture body 3. The insertion rods 6 are located inside the insertion holes 2. The insertion rods 6 are inserted into the insertion holes 2. The fixing rod 806 moves into the fixing hole 7 to ensure a more secure connection between the fixture body 3 and the base 1. While facilitating quick disassembly of the fixture body 3, the fixing effect between the fixture body 3 and the base 1 is not affected. The outer side of the insertion rod 6 is provided with a fixing hole 7.

[0029] like Figure 4 As shown, a disassembly assembly 8 is connected to one side of the interior of the base 1. The disassembly assembly 8 includes a mounting seat 81 installed in the middle of the upper end of the base 1. The mounting seat 81 is located inside the groove 4. A rotating rod 82 is rotatably connected to one side of the interior of the mounting seat 81. The lower end of the rotating rod 82 extends through to the interior of the base 1. The lower end of the rotating rod 82 is rotatably connected to the bottom end of the interior of the base 1.

[0030] The rotating rod 82 is fitted with a rotating seat 83. The lower end of the rotating seat 83 is rotatably connected to the bottom of the base 1. The upper end of the rotating seat 83 is fixedly connected to a toothed plate 85. The rotation of the toothed plate 85 drives the second gear 801 and the rotating seat 83 to rotate simultaneously. Fixed units 86 are connected around the upper end of the toothed plate 85. A first gear 87 is meshed on one side of the upper end of the toothed plate 85. The rotation of the rotating shaft 88 drives the first gear 87 to rotate. The first gear 87 meshes with the toothed plate 85, thereby driving the toothed plate 85 to rotate. One end of the first gear 87 is connected to the rotating shaft 88, and one end of the rotating shaft 88 extends through to the outside of the base 1.

[0031] like Figure 5As shown, the rotating rod 82 has a threaded groove 89 on its outside. A movable plate 810 is threadedly connected to the outside of the threaded groove 89. With the threaded groove 89, when the rotating rod 82 rotates, the movable plate 810 moves the magnetic sleeve 812 upward or downward. The upper end of the movable plate 810 is connected to the magnetic sleeve 812. The magnetic sleeve 812 generates a magnetic attraction force to attract the magnetic block 815, which in turn causes the magnetic block 815 to move the snap-fit ​​block 813. Both sides of the upper end of the movable plate 810 are connected to round rods. Both ends of the round rods are connected to the inner walls of the mounting base 81. Snap-fit ​​blocks 813 are connected to the outer perimeter of the mounting base 81. One end of the snap-fit ​​block 813 extends into the snap-fit ​​groove 5.

[0032] like Figure 6 As shown, a magnetic block 815 is connected to the middle of one end of the snap-fit ​​block 813. Slide rods 816 are connected to both sides of one end of the snap-fit ​​block 813. A support plate 817 is connected to one end of each slide rod 816, providing support for the slide rod 816. One end of the support plate 817 is connected to one side of the inner wall of the mounting base 81. A circular plate 818 is connected to the other end of the slide rod 816, extending through the interior of the snap-fit ​​block 813. The circular plate 818 limits the movement of the slide rod 816, preventing it from detaching from the snap-fit ​​block 813. 6. An external spring 819 is provided. The spring 819 has elastic potential energy. When the magnetic sleeve 812 and the magnetic block 815 are in the same straight line, the magnetic block 815 moves towards the magnetic sleeve 812 and squeezes the spring 819, so that the spring 819 is in a compressed state. When the magnetic sleeve 812 is not in the same straight line as the magnetic block 815, the elastic potential energy of the spring 819 pushes the locking block 813 to move to its original position. One end of the spring 819 is connected to one side of the locking block 813, and the other end of the spring 819 is connected to one side of the support plate 817.

[0033] like Figure 7 As shown, the fixing unit 86 includes a second gear 801 meshing with the upper end of the toothed plate 85. One end of the second gear 801 is connected to a transmission rod 802. A support plate 803 is sleeved on the outside of the transmission rod 802. The support plate 803 provides rotational support for the transmission rod 802. The lower end of the support plate 803 is connected to one side of the inner wall of the base 1. A limit plate 805 is connected to one side of the inside of the transmission rod 802. The limit plate 805 limits the movement distance of the fixing rod 806 to prevent the fixing rod 806 from separating from the transmission rod 802.

[0034] One end of the limiting plate 805 is connected to a fixing rod 806. The fixing rod 806 moves into the fixing hole 7 under the drive of the lead screw 808 to fix the plug rod 6, ensuring that the fixture body 3 is easy to disassemble while the connection between it and the base 1 remains firm, preventing the fixture body 3 from shifting and affecting processing. One end of the fixing rod 806 extends through into the fixing hole 7. A threaded hole 807 is opened at one end of the fixing rod 806. The lead screw 808 is threadedly connected to the inside of the threaded hole 807. The lead screw 808 is threadedly connected to the threaded hole 807. When the lead screw 808 rotates under the drive of the transmission rod 802, the lead screw 808 drives the fixing rod 806 to move. One end of the lead screw 808 extends through into the transmission rod 802 and is connected to one side of the inside of the transmission rod 802.

[0035] The implementation principle of the quick-change fixture structure for chip testing in this application embodiment is as follows: In the initial state of use, the base 1 is fixedly connected to the fixture body 3, the snap-fit ​​block 813 is located inside the snap-fit ​​groove 5, and the fixing rod 806 is located inside the fixing hole 7. When it is necessary to disassemble and replace the fixture body 3, the rotating shaft 88 is rotated, which drives the first gear 87 to rotate. The rotation of the first gear 87 drives the gear plate 85 to rotate, and the rotation of the gear plate 85 drives the second gear 801 and the rotating rod 82 to rotate simultaneously. The rotation of the second gear 801 drives the transmission... When rod 802 rotates, lead screw 808 is threadedly connected to threaded hole 807. As lead screw 808 rotates, fixed rod 806 moves out of fixed hole 7. Fixed rod 806 is no longer fixedly connected to plug rod 6. Rotating rod 82 drives moving plate 810 to move upward along threaded groove 89. When magnetic sleeve 812 and magnetic block 815 are on the same horizontal plane, the snap-fit ​​block 813 moves into mounting base 81 under the attraction of magnetic sleeve 812, so that fixture body 3 is no longer fixed to base 1, making it easy to disassemble and replace fixture body 3.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
