The specific embodiment is as follows:

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, in the embodiment of the utility model, the special vernier for CT image measurement includes a positioning fixture block 1, a positioning plate 2, a sliding main scale 3 and a cursor 4, wherein a clamping groove 11 for clamping the edge of the CT image 5 is provided on one side of the positioning fixture block 1 facing the positioning plate 2, the head end of the positioning plate 2 is connected with the positioning fixture block 1, the positioning plate 2 is in a strip shape, the sliding main scale 3 is slidably connected with the positioning plate 2, a row of main scale lines are provided on the lower edge of the sliding main scale 3, a first measuring claw 31 is provided on the left end of the lower edge of the sliding main scale 3, a cursor 4 is slidably mounted below the sliding main scale 3, an indexing scale line is provided on the upper edge of the cursor 4 corresponding to the sliding main scale 3, and a second measuring claw 41 is provided on the left end of the lower edge of the cursor 4.
