The through hole 34 is opened in the middle of the fixing plate 30. The adjusting screw 35 is screwed in the through hole 34, and the pressure plate 36 is rotatably connected to the lower end of the adjusting screw 35.

[0035] The pressure plate 36 is located between the fixing plate 30 and the connecting frame 31, and the lower surface is movably connected to the upper end of the sensor probe 14;

[0036] The fixing plate 30 plays a supporting role, the connecting frame 31 plays a connecting role, the first groove 32 plays a limiting role, the metal tie 33 plays a fastening role, the through hole 34 plays a connecting and adjusting role, the adjusting screw 35 plays an adjusting role, and the pressure plate 36 plays a connecting role.

[0037] Working principle:

[0038] The sensor probe 14 is bonded to the end face of the bolt 20 , the connecting frame 31 is held, and the lower end of the connecting frame 31 is attached to the end face of the bolt 20 , the metal tie 33 is stuck in the first groove 32 and tightened and fixed, and the adjusting screw 35 in the through hole 34 is rotated to drive the pressure plate 36 to move downward and fit closely to the upper surface of the sensor probe 14 .

[0039] This step ensures the stability of the connection of the sensor probe 14 and facilitates later disassembly.

[0040] See also Figure 3 , Figure 5 This embodiment is based on the above embodiment and further includes:

[0041] The splicing assembly includes a clamping plate 44 and a second groove 45. The clamping plate 44 is movably connected to the middle of the lower end of the frame 31, and the second groove 45 is opened in the middle of the outer side of the clamping plate 44;

The torsion spring 42 is sleeved on both ends of the connecting shaft 41, and one end is fixed to the side of the U-shaped fixing frame 40, and the other end is fixed to the side of the L-shaped connecting plate 43.

[0045] Working principle:

[0046] When the end face of the bolt 20 is smaller than the sensor probe 14 and the internal position of the connecting frame 31 is larger, the clamping plate 44 is rotated to drive the L-shaped connecting plate 43 to rotate around the connecting shaft 41 between the U-shaped fixing frame 40, so that the clamping plate 44 is close to the side of the end face of the bolt 20, and is clamped in the second groove 45 with the metal cable tie 33 and tightened and fixed. At this time, the sensor probe 14 can be pressed by the adjusting screw 35 and the pressure plate 36. When the larger bolt 20 is connected, the clamping plate 44 and the L-shaped connecting plate 43 are rotated 180 degrees in the opposite direction around the connecting shaft 41 under the action of the torsion spring 42, so that the clamping plate 44 is connected to the outside of the connecting frame 31, that is, it does not affect the connection between the connecting frame 31 and the bolt 20.
