[0022] In the embodiment, the mounting base 1 is used for being mounted on the rack of the numerical control machine tool and is away from the worktable of the numerical control machine tool.

[0023] Specifically, the driver 3 is an extension cylinder, the number of the guide sliding grooves 5 is two, the driver 3 is fixed to the mounting base 1 through a fixing piece 11, the mounting base 1 is fixed with two sliding blocks, the two sliding blocks are respectively provided with the two guide sliding grooves 5, and the driver 3 and the two guide sliding grooves 5 are on the same side of the mounting base 1, so as to form a compact arrangement.

[0024] The guide rail 4 is limited by the connecting piece 8 and the guide sliding groove 5 on the mounting base 1, so as to realize the stable forward and backward linear sliding of the guide rail 4 under the driving of the extension cylinder, thereby ensuring the stability of the movement track of the tool setting sensor 2, and thus the tool setting precision of the tool setting gauge can be improved.
