When working, the annular magnet is placed at the bottom of the detection chamber 1, and the insertion rod 17 passes through the threaded hole on the annular magnet, thereby limiting and fixing the annular magnet. When the threaded hole of the annular magnet is not compliant, it cannot pass through the insertion rod 17, which is convenient for rapid detection of the threaded hole of the annular magnet. Turning the handle drives the adjusting screw 12 to rotate, so that the adjusting slider moves inward and outward, driving the outer ring sleeve 14 to move, thereby limiting and fixing the annular magnet, further improving the stability of the placement of the annular magnet, and the first measuring ruler 11 plays a role in detecting the diameter size of the annular magnet.

[0023] The upper and lower end surfaces of the adjusting slider are installed with an annular sleeve 18, and the annular sleeve 18 is connected to the first measuring ruler 11 by a sliding fit. When working, the annular sleeve 18 moves with the adjusting slider, so that the value on the first measuring ruler 11 can be accurately read, thereby measuring the diameter of the annular magnet.

The second measuring ruler 21 structure is adopted to facilitate the precise adjustment of the position of the insertion rod 17, so that the adjustment positions of multiple insertion rods 17 remain consistent.

[0025] A bottom plate is installed at the bottom of the detection chamber 1, and a plurality of adjusting spring rods 26 are symmetrically installed on the left and right side walls of the bottom plate. An inner ring sleeve is installed at the other end of the adjusting spring rod 26.

When the threaded hole of the annular magnet is not compliant, it cannot pass through the rod 17, which is convenient for rapid detection of the threaded hole of the annular magnet. The handle is turned to drive the adjusting screw 12 to rotate, so that the adjusting slider moves inward and outward, and drives the outer ring sleeve 14 to move, so as to limit and fix the annular magnet, further improving the stability of the placement of the annular magnet. The first measuring scale 11 plays a role in detecting the outer diameter of the annular magnet.
