second guiding mechanism (5) include second L type supporting shoe (51), and a plurality of second L type supporting shoe (51) are fixed respectively and set up first guide way (11) both sides of lateral wall around base (1), the other end of second L type supporting shoe (51) rotates and is equipped with second round pin axle (52), the tip of second round pin axle (52) rotates and is equipped with second guide roller (53), and second guide way (22) have all been seted up to both sides lateral wall around two protective cover (2), second guide roller (53) roll and set up inside same one side second guide way (22).

10. A method for protecting a storage case for a precision measuring tool, which comprises the step of using the storage case for a precision measuring tool according to claim 1, comprising the steps of:

a1, placing the precision measurement tool to be circulated and carried on a base (1), butting the two protective covers (2) together and then covering the protective covers on the base (1), namely, storing the precision measurement tool by utilizing a storage space formed by the inner sides of the two protective covers (2) and the upper end face of the base (1);

a2, the first guide mechanism (3) is utilized to ensure that the two protective covers (2) can slide relatively and oppositely, namely the two protective covers (2) are attached together and separated from each other, and the two protective covers (2) cannot be distributed in a staggered way;

a3, after the precision measurement tool is placed in the storage space, the four limit pieces (4) are distributed at the four corner positions of the precision measurement tool, so that the limit purpose of the precision measurement tool is realized, and the collision between the precision measurement tool and the inner wall of the protective cover (2) is avoided.
