Detailed Description

Example (b): an anti-collision point collection type magnetic particle flaw detector probe is shown in figures 1 and 2 and comprises a probe handle 1, wherein one end of the probe handle 1 is fixedly connected with a plurality of probe bodies 2. When in use, the probe handle 1 is held, the probe body 2 is pressed against a workpiece to be detected, and then the region of the workpiece can be detected.

As shown in fig. 1 and 2, the probe handle 1 is slidably connected with side baffles 11 parallel to the plane of the probe handle 1 at the positions corresponding to the two sides of the probe body 2. The surfaces of the probe handle 1 close to the two side baffles 11 are fixedly connected with supporting rods 111 which are perpendicular to the plane where the side baffles 11 are located, and the cross sections of the supporting rods 111 are arranged in a square shape. Support holes 112 are formed in the positions, close to the support rods 111, of the side baffles 11, and the support rods 111 can be connected to the support holes 112 in a sliding mode along the length direction of the support rods 111. The support holes 112 are elongated holes, the support holes 112 are arranged along the length direction of the probe body 2, and the support rods 111 can be slidably connected in the support holes 112 along the length direction of the probe body 2. The positions of the mutually close surfaces of the baffles 11 at the two sides, which correspond to the probe body 2, are fixedly connected with protective layers 114 with the cross sections larger than that of the probe body 2, and the protective layers 114 are made of soft materials such as sponge and the like. When the probe body 2 is not needed, the two side baffles 11 can slide oppositely, the protective layer 114 on the two side baffles 11 is used for clamping the probe body 2, the probe body 2 is protected, when the probe body 2 is needed to be used for detection, the side baffles 11 can slide towards one end far away from the probe body 2, so that the probe body 2 is exposed, and the detection process cannot be influenced by the side baffles 11 when the probe body 2 is ensured to be detected. Meanwhile, the side baffle 11 can effectively reduce the impact of the collision on the probe body 2.

As shown in fig. 1 and 2, the side guard 11 is provided with a stopper mechanism 12.
