When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a centering mark tool comprises a substrate 1, the substrate 1 includes a central plate 11 and a plurality of diffusion plates 12, the central plate 11 is circular, a plurality of diffusion plates 12 are evenly spaced around the central plate 11, a through hole 111 is formed in the center of the central plate 11, a chute 121 is formed in the diffusion plates 12, a vertical plate 122 is arranged at one end, far away from the central plate 11, of the diffusion plates 12, one end of a guide rod 3 is connected with the vertical plate 122, the guide rod 3 is arranged at intervals side by side with the chute 121, a spring 4 and a sliding block 5 are sleeved on the guide rod 3, one end of the spring 4 is connected with the vertical plate 122, the other end of the spring is in butt joint with the upper end of the sliding block 5, the lower end of the sliding block 5 is movably clamped on the chute 121, a locking rod 6 is further arranged on the sliding block 5, the lower end of the locking rod 6 sequentially penetrates through the sliding block 5 and a bearing 7, and the outer peripheral wall of the bearing 7 is movably in butt joint with the side wall of a workpiece.
