During the detection, the base 31 can be abutted to the detected metal plate, the upper gap of the detection ruler 1 extends into the gap, the connecting rod 32 moves in the through groove, the connecting rod 32 also has the pointer function of the reading ruler 3, and the scales are read through the connecting rod 32.
Preferably, the device also comprises a spring 4 which is sleeved outside the shaft lever 2; the top of the shaft 2 forms an upper cover 5, and the spring 4 is located between the rod sleeve 33 and the upper cover 5. After the detection is finished, the detection ruler 1 can be automatically reset. The upper cover 5 is provided with a screw hole which is in threaded connection with the shaft lever 2. It will be appreciated that the upper cover 5 is a preferred embodiment, as long as it enables limiting the movement of the upper end of the spring 4 to be used in the present application, for example by providing a protruding shaft on top of the shaft 2 to block the spring 4.
The through groove is positioned at the part of the periphery of the shaft lever 2 to form an accommodating cavity. The accommodating cavity provides an accommodating space for the shaft lever 2, and also provides a space for the lever sleeve 33, so that the lever sleeve can be sleeved outside the shaft lever 2 and can slide relatively (certainly, slide along the axial direction) relative to the shaft lever 2 and the through groove of the detection ruler 1.
The reading scale also has a foot 34, although this is only a preferred embodiment, the foot 34 being shown in figure 1, fixedly attached to the underside of the base 31. In use, the foot 34 bears against the surface of the sheet metal being inspected. Preferably, the legs 34 may be provided with magnets to directly adhere to the metal plate to ensure stability.
