[0024] Specifically, the fixed angle assembly 4 includes an active cavity 41, a positioning column 42, a return spring 43, a limit ring 44, a cylindrical slider 45, a truncated cone block 46, and an adjusting knob 47.

[0025] 41 is hollow and arranged in the hinge column 2, and a truncated cone block 46 is sleeved in the movable cavity 41. One end of the truncated cone block 46 is coaxially rotatably connected to one end of the adjusting knob 47. The adjusting knob 47 is connected to the hinge column 2 through a threaded structure. The two sides of the truncated cone block 46 respectively abut against one end of a cylindrical slider 45, and the other end of the cylindrical slider 45 is respectively fixedly connected to one end of a positioning column 42. The positioning column 42 is slidably connected to the hinge column 2. A return spring 43 is movably sleeved outside the positioning column 42. One end of the return spring 43 is fixedly connected to the inner wall of the movable cavity 41, and the other end of the return spring 43 is fixedly connected to a limiting ring 44. The limiting ring 44 is fixedly sleeved on the positioning column 42, and the positioning column 42 is engaged with the card slot 31.

[0026] When used for detection, according to the angle of the detection position, adjust the angle between the L-shaped rod 5 and the center line of the detector body 1 to a suitable position, and then operate the adjustment knob 47 of the fixed angle component 4. When the adjustment knob 47 is rotated, the threaded structure drives the truncated cone block 46 to move, and the truncated cone block 46 contacts the cylindrical slider 45. The cylindrical slider 45 drives the fixed positioning column 42 to be inserted into the slot 31, thereby limiting and fixing the hinge ring 3 to keep the position of the L-shaped rod 5 fixed.

[0027] Specifically, the inner walls on both sides of the storage slot 8 are respectively recessed with a plurality of cylindrical slots 81, and the middle of the cylindrical slots 81 are provided with movable slots 82. The movable slots 82 are set through, and the through setting facilitates the movement of the movable column 74 of the positioning component 7, and then determines the length of the lifting strap 6, which is convenient for use by inspection personnel with different arm circumferences.

[0028] Specifically, the positioning assembly 7 includes a connecting tube 71, a tightening spring 72, a columnar clamping block 73, a movable column 74, and a pressing plate 75. The connecting tube 71 is slidably arranged in the storage groove 8. The connecting tube 71 is respectively fixedly connected to the two ends of the pulling belt 6. The two sides of the connecting tube 71 are respectively slidably sleeved with the columnar clamping block 73. The opposite ends of the columnar clamping block 73 are respectively fixedly connected to the two ends of the tightening spring 72. The tightening spring 72 is movably arranged in the connecting tube 71. The opposite ends of the columnar clamping block 73 are respectively coaxially fixedly connected to one end of the movable column 74, and the other end of the movable column 74 is fixedly connected to the pressing plate 75.

The movable column 74 drives the column block 73 to be received into the connecting tube 71, and the column block 73 is disengaged from the clamping of the column slot 81. Then the pressing plate 75 is moved to drive the movable column 74 to move in the movable slot 82, so that the lifting belt 6 is extended from the storage slot 8, and the arm of the inspector is extended between the lifting belt 6 and the detector body. After the lifting belt 6 is tied outside the arm, the pressing plate 75 is released, and the elastic force of the tightening spring 72 drives the column block 73 to be clamped into the column slot 81, thereby fixing the length position of the lifting belt 6, and then the detector body 1 is tied to the arm of the inspector with the lifting belt 6, so as to facilitate the detection work.

[0031] Example 3

When in use, the lifting belt 6 forms a straight-line structure, and the two ends of the lifting belt 6 are respectively stored in the storage groove 8. The lifting belt 6 is a fiber belt or a plastic belt, which is inelastic. After being pulled into a straight-line structure, it cooperates with the L-shaped rod 5 to facilitate the detection personnel to carry the detector body 1 by hand. When used for detection, according to the angle of the detection position, the angle between the L-shaped rod 5 and the center line of the detector body 1 is adjusted to a suitable position, and then the adjustment knob 47 of the fixed angle component 4 is operated. When the adjustment knob 47 is rotated, the threaded structure drives the truncated cone block 46 to move, and the truncated cone block 46 contacts the cylindrical slider 45. The cylindrical slider 45 drives the fixed positioning column 42 to be clamped into the clamping groove 31, thereby limiting the hinge ring 3. The locking cam 73 is then released and the locking cam 74 is in the locked state, so that the locking cam 73 is locked and the locking cam 73 is in the locked state.
