Detailed Description

The utility model is further elucidated below in conjunction with the accompanying drawings.

The orientations referred to in the present specification are all based on the orientations of the depth gauge of the present utility model when the depth gauge is in normal operation, and are not limited to the orientations during storage and transportation, but only represent relative positional relationships, and not absolute positional relationships.

Embodiment one:

as shown in fig. 1 and 2 together, a depth gauge comprises a frame 1 and a blade 2 slidably mounted on the frame 1, wherein scales are correspondingly arranged on the frame 1 and the blade 2, so that numerical values can be read. The both sides of the degree of depth measurement face 11 of chi frame 1 are fixed with backup pad 3, and the bottom and the degree of depth measurement face 11 parallel and level of backup pad 3 are provided with the slide on the backup pad 3, and extension board 4 slidable mounting is in the slide. The side wall of the supporting plate 3 is further provided with a bolt hole, the bolt hole penetrates through the side wall of the supporting plate 3, the locking bolt 31 is installed in the bolt hole in a matched mode, and after the locking bolt 31 is screwed down, the inner end portion of the locking bolt 31 abuts against the extension plate 4.
