Detailed Description
The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.
As shown in fig. 1 to 5, the present invention provides a transportation positioning device used in a dust-free environment, which includes a supporting frame 1 and a driver 6, wherein the supporting frame 1 is i-shaped. Even there are two relative first riser 2 and the second riser 13 that sets up on support frame 1, and the shape of first riser 2 and second riser 13 is the rectangular bodily form, and first riser 2 and second riser 13 and support frame 1 welded fastening.
