Specifically, the sliding shell is slidably mounted on the probe body, under the action of spring pressure in a natural state, the lower end of the magnetic ring is close to the lower end of the probe body, under the action of magnetic force between the magnetic ring and a workpiece to be detected, the probe is adsorbed on the surface of the workpiece to be detected, when the probe needs to be moved or removed, the sliding shell and the magnetic ring can be driven to move upwards by pressing the lower ring upwards, the magnetic ring is separated from the workpiece, the magnetic adsorption force is reduced, the probe is convenient to move or remove, the lower ring is released after the probe is moved to a new position, and the probe can be adsorbed on the surface of the workpiece. The upper end of the upper sleeve can be abutted against the lower end face of the upper ring after the lower ring is pressed in place, so that the probe can be conveniently held.

According to another embodiment of the present invention, it further comprises a bellows sleeve connected between the upper ring and the lower ring, wherein the bellows sleeve is sleeved outside the spring. Through setting up the ripple cover, including the spring parcel, make the probe appearance more pleasing to the eye, and avoid the spring extrusion finger during the use.

According to another embodiment of the present invention, further comprising the lower ring being threadedly connected to the upper housing. Through the lower ring that sets up threaded connection, can adjust the position of lower ring on last cover, according to the extension of using habit adjustment spring to the pressing resistance size of adjustment lower ring makes the probe use more comfortable.

According to another embodiment of the utility model, the lower ring is abutted with a locking ring, and the locking ring is in threaded connection with the upper sleeve. Through setting up the locking ring, support the lower ring with the locking ring after the ring position is down adjusted, it is not hard up to avoid the lower ring when using.

According to another embodiment of the utility model, the functional part is provided with a rubber ring on the upper shoulder surface. When can slow down the release lower ring through setting up the rubber circle, the impact of sliding sleeve and probe body reduces the collision noise, uses the rubber circle of different thickness simultaneously can adjust the clearance of magnetic ring and workpiece surface to the adsorption affinity size of adjustment probe and work piece makes things convenient for the probe to use.

The utility model has the advantages that the adjustable magnetic ring structure is arranged, so that the end face of the probe is abutted against the surface of the workpiece, the detection accuracy is improved, particularly the detection on the inner wall surface which is inconvenient to press in the workpiece is improved, the hand fatigue of an operator during the detection operation is reduced through the automatic adsorption force between the probe and the workpiece, and the working efficiency is improved.
