A counterweight is placed in the counterweight placement groove 7 to prevent the support platform from being touched and moved due to being too light. The entire support platform body is made of EPE pearl cotton material, which has strong flexibility and can protect the tool product. Even if the blade falls and collides with the support platform during clamping, the cutting edge will not be damaged.

[0031] The spacer bead placement groove 6 is used to place a large number of spacer beads. A large number of cutting tools to be clamped are pre-placed on the upper right part of the upper platform 2. The gear-shaped base 10 is placed on the lower platform 1, and the support bar 9 blocks the gear-shaped base 10. The gear-shaped base 10 is partially embedded in the wedge-shaped mouth of the pearl cotton to prevent the gear-shaped base 10 from moving at will.
