The middle part of the second force rod 34 is connected with a third rotating shaft 341, the middle part of the third rotating shaft 341 is provided with a second pull groove 342, one end of the pulling spring 38 is hooked in the second pull groove 342, and the other end of the pulling spring 38 is hooked in the first pull groove 322, so that the pulling spring 38 can provide a pulling force for each of the second force rod 34 and the counterweight mechanism 33.

Referring to fig. 7, when the device is not opened, the rotating shaft in the machine body 1 is at a standstill, the entire probe fixing device 3 is at a standstill, and the probe 30 elastically connected to the side plate 355 is also at a standstill. At this time, the weight 331 is in contact with the second stopper 37 under the action of the pulling force of the pulling spring 38, the support seat 32 drives the hinge frame 353 and the side plate 355 to be away from the workpiece 4 to be detected through the two-force rod 34, and the probe 30 is also away from the workpiece 4 to be detected.
When the device is opened, the rotating shaft in the machine body 1 rotates, the magnetic circuit guide piece 2 is driven to rotate through the turntable seat 21, and then the probe fixing device 3 is driven to rotate accordingly. At this time, each component mechanism in the probe fixing device 3 generates an additional centrifugal force, and because the weight 331 and the probe 30 have larger mass, and the lever principle causes the partial acting force of the weight 331 and the probe 30 to be much larger than the centrifugal force of other components, the centrifugal force of other components is ignored during the stress analysis.
The supporting seat 32 is subjected to stress analysis, at the moment, the counterweight 331 is subjected to the action of centrifugal force F1 and the pulling force of the pulling spring 38, when the moment of the rotating center is larger than the moment of the pulling force F2 of the pulling spring 38 due to the centrifugal force F1, the supporting seat 32 has a rotating tendency, the two-force rod 34 is pressed at the moment, the supporting seat 32 is subjected to pressure F3 from the two-force rod 34, meanwhile, the hinged seat 353 can also be subjected to pressure F5 of the two-force rod 34, and the two forces are equal in magnitude and opposite in direction.
For the force analysis of the hinge seat 353, the side plate 355 and the probe 30 connected to one side of the side plate 355 are also subjected to centrifugal force, and the resultant force of the centrifugal force is F6. When the moment of the pressing force F5 to the rotation center is larger than the moment of the centrifugal force F6 to the rotation center, the hinge base 353 rotates until it stops moving when hitting the first shutter 36, and at this time, the probe 30 contacts the outer surface of the workpiece 4 to be detected.
When the device is shut down, the rotating shaft in the machine body 1 is decelerated and gradually stops, centrifugal forces F1 and F6 gradually disappear, and the device is restored to a non-opening state under the action of pulling force F2 of the pulling spring 38.
Through the above stress analysis, it can be known that, in the present invention, the probe fixing device 3 is installed inside the magnetic circuit guide 2 for elastically connecting the probe 30 of the workpiece 4 to be detected, so that the probe fixing device 3 and the probe 30 generate centrifugal force during the rotation operation of the rotating shaft in the machine body 1, the hinge seat 353 rotates, the side plate 355 at the top of the hinge seat 353 is driven to collide with the first baffle 36, and the probe 30 contacts the outer surface of the workpiece 4 to be detected. When the rotation shaft in the machine body 1 stops moving, the centrifugal force applied to the probe fixing device 3 and the probe 30 gradually disappears, the counterweight 331 contacts the second stopper 37 under the action of the pulling force F2 of the pulling spring 38, the support seat 32 drives the hinge frame 353 and the side plate 355 to be away from the workpiece 4 to be detected through the two-force rod 34, and the probe 30 is also away from the workpiece 4 to be detected. To sum up, the rotation axis rotation during operation in the organism 1 finally leads to probe 30 to contact the surface of waiting to detect work piece 4, when the rotation axis stop work or static in the organism 1, probe 30 keeps away from the surface of waiting to detect work piece 4, makes like this probe 30 and work piece 4 be in a good contact detection environment at the during operation, in time detects work piece 4, guarantees the rate of accuracy that the magnetic leakage detected, still has the effect of saving the power for whole magnetic leakage detection equipment.
