[0028] As attached Figure 1 To the attached Figure 7 As shown:

[0029] The utility model provides a crack width electromagnetic testing device, including a sensor body 1, a processor body 2 and a connecting line 3. A mounting seat 101 is installed at the top of the sensor body 1, and a mounting groove 102 is penetrated through the top of the mounting seat 101. A threaded rod 103 is rotatably installed in the mounting groove 102. The circumferential side of the threaded rod 103 is threadedly connected to a connecting ring 104. Four support rods 105 are equidistantly installed at the bottom end of the connecting ring 104. A ball 106 is installed at the bottom end of the support rod 105. A protective component is installed at the bottom end of the sensor body 1, an elastic band 201 is installed at the bottom end of the processor body 2, and an extension block 301 is installed at one end of the connecting line 3.

[0030] A slot 107 is provided through the middle of the threaded rod 103 to facilitate inserting the connecting line 3 into the sensor body 1 and connecting the sensor body 1 and the processor body 2 together.

[0031] Among them, the protective component includes an annular slide 108 and a protective cover 109. The annular slide 108 is opened at the bottom end of the sensor body 1, and four second slide grooves 110 are equidistantly arranged on the circumference of the annular slide 108. A slider 111 is slidably installed in each second slide groove 110, and one end of the slider 111 extends to the outside of the second slide groove 110. The slider 111 is provided with a spherical protrusion at one end located outside the second slide groove 110. An annular clamping block 112 is installed on the top of the protective cover 109, and four grooves 113 are equidistantly arranged on the inner side of the annular clamping block 112. The protective cover 109 can protect the sensor body 1 to prevent foreign objects from touching the lens part of the sensor body 1 and causing wear on the lens during carrying. When the sensor body 1 needs to be used, the staff can rotate the protective cover 109 so that the inner side of the annular clamping block 112 squeezes the slider 111 and disengages from the groove 113, and then pulls the protective cover 109 downward to remove the protective cover 109.

[0032] Among them, the slider 111 is installed with a compression spring 114 at one end located inside the second slide groove 110, and the other end of the compression spring 114 is connected to one side of the second slide groove 110. Through the rebound of the compression spring 114, the slider 111 can be fixed in the groove 113 and the protective cover 109 is fixed.

[0033] The size of the annular clamping block 112 matches the size of the annular chute 108 , so that the annular clamping block 112 can enter the annular chute 108 .

[0034] The position and size of the groove 113 respectively match the position and size of the side of the slider 111 provided with the spherical protrusion, so that the slider 111 can enter the groove 113.

[0035] The sensor body 1 and the processor body 2 are electrically connected via a connecting line 3 .

[0036] The working principle of the embodiment is as follows: when the crack width electromagnetic testing device is used, the staff first connects the sensor body 1 and the processor body 2 together through the connecting line 3, then rotates the threaded rod 103, since the supporting rod 105 is limited by the mounting seat 101 and the supporting rod 105 is connected with the connecting ring 104, at this time, the connecting ring 104 moves downwards on the threaded rod 103 and drives the supporting rod 105 and the ball 106 to move downwards, so that the ball 106 can contact the two sides of the crack, after the position of the ball 106 is adjusted, the staff rotates the protective cover 109, so that the inner side of the annular clamping block 112 extrudes the sliding block 111 and is separated from the groove 113, then the protective cover 109 is pulled downwards, the protective cover 109 is removed, and the sensor body 1 is used to measure the crack width, after use, the staff re-inserts the annular clamping block 112 into the annular sliding groove 108 and rotates the annular clamping block 112, so that the groove 113 is moved to the position aligned with the sliding block 111, at this time, under the action of the elastic recovery of the compression spring 114, the sliding block 111 enters the groove 113 and fixes the protective cover 109.
