[0012] Preferably, a stepped groove is provided on the outer circle of the suspended groove, and the depth of the stepped groove is 5 mm.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a positioning groove and a positioning mechanism on the upper cover. When the chip needs to be transferred, the chip is placed horizontally on the positioning mechanism. Then, through the existing negative pressure adsorption technology (the negative pressure adsorption equipment is fixed in the suspended groove), the chip on the positioning mechanism is negatively adsorbed from the inside of the suspended groove through the first through hole and the second through hole, so that the chip remains fixed, so that the chip will not shake or shift during the transfer process, and the fixture is prevented from directly contacting the chip and generating squeezing force on the chip, so that the chip will not be damaged or scratched on the chip surface.
