[0025] In this embodiment, Figure 1 and Figure 2As shown, the external thread of the threaded rod 14 is connected to a threaded sleeve 15, and the threaded sleeve 15 is fixedly connected to the rectangular plate 8. The rotation directions of the threads at both ends of the threaded rod 14 are opposite. A socket 10 is opened in the top plate 3, and a steel plate 13 is slidably connected in the bottom plate 1. A micro cylinder 12 is installed on the top of the steel plate 13, and an insertion rod 11 is fixedly connected to the side of the micro cylinder 12. The insertion rod 11 passes through the socket 10 and extends into the rectangular plate 8.

[0026] Among them, the threaded rod 14 is driven to rotate under the power of the driving motor 18, and the limit ring 5 and the extrusion plate 7 are driven to move through the threaded connection between the threaded rod 14 and the threaded sleeve 15. The chip is clamped and fixed by the extrusion plate 7, and the extrusion force exerted on the chip body 6 is monitored under the pressure monitoring of the pressure sensor 16 to avoid damage to the chip body 6 due to a large extrusion force.

[0027] In this embodiment, Figure 3 and Figure 4 As shown, the bottom of the steel plate 13 is hinged with a vertical plate 23 through a rotating rod 24, and the top of the vertical plate 23 is fixedly connected to a connecting plate 22. A bottom groove 21 is provided at the bottom of the bottom plate 1, and the connecting plate 22 extends into the bottom groove 21 and is slidably connected to the bottom groove 21.
