Further, the operation block, the dotting rod and the connecting ring are coaxially arranged, and accuracy of a final dotting position is guaranteed.

Further, the connecting ring is welded on the positioning plate.

Furthermore, the end of the dotting rod is sleeved with a magnet block, and the magnet block is used for fixing the positioning plate on the wall of the cargo compartment.

Furthermore, the positioning holes are horizontally and symmetrically formed in the positioning plate.

Has the advantages that: compared with the prior art, the utility model, possess following advantage:

1. a plurality of dotting operations and marking operations can be synchronously realized, and dotting and marking efficiency is improved.

2. Through the matching design of the positioning holes and the dotting devices, the relative positions of adjacent dotting points are determined, precision errors caused by dotting operation errors and marking errors are eliminated, the accuracy of all dotting positions is ensured, and the smooth installation of subsequent insulating plates is ensured.

3. Can realize drawing a line through drawing a line opening, but solve the big problem of error that the marking off mode of current experience and operation exists, promote the marking off precision, ensure the marking off degree of accuracy.
