1. An assembly for carrying a chip, configured to fasten chips of different sizes, and comprising:
a rotatable vertical rod, provided with a gear that surrounds the rotatable vertical rod with gear teeth;
a cross beam, internally provided with a first through hole and a first chute, an extension direction of the first chute being consistent with an extension direction of the cross beam;
a first sidewall, a top of the first sidewall being connected to a first connecting rod located in the first chute; and
a second sidewall, spaced apart from the first sidewall, and configured to fasten a chip between the first sidewall and the second sidewall, a top of the second sidewall being connected to a second connecting rod spaced apart from the first connecting rod and located in the first chute, and a side surface of the first connecting rod close to the second connecting rod being provided with a plurality of first tooth grooves arranged linearly; and,
wherein the rotatable vertical rod is configured to rotate in the first through hole and drive the gear to rotate, so that the gear teeth of the gear are engaged with the first tooth grooves, to drive the first sidewall to be relatively close to the second sidewall or relatively distant from the second sidewall; and the assembly further comprises
a third sidewall, a top of the third sidewall being connected to a third connecting rod, the third connecting rod passing through the cross beam and the first through hole through a second chute formed in the cross beam; and
a fourth sidewall, spaced apart from the third sidewall, and configured to fasten a chip between the third sidewall and the fourth sidewall, a top of the fourth sidewall being connected to a fourth connecting rod spaced apart from the third connecting rod and located in the second chute, and a side surface of the third connecting rod close to the fourth connecting rod being provided with a plurality of third tooth grooves arranged linearly, wherein the rotatable vertical rod is configured to rotate in the first through hole and drive the gear to rotate, so that the gear teeth of the gear are engaged with the third tooth grooves, to drive the third sidewall to be relatively close to the fourth sidewall or relatively distant from the fourth sidewall.
