[0029] A shielding structure 6 is provided on the surface of the machine body 1 for temporarily shielding the steel bars 5 to be detected, and an auxiliary structure 7 is provided on the surface of the machine body 1 for temporarily protecting the control panel 4 .

[0030] In order to prevent the steel bars from flying out due to breakage, Figure 2-3 As shown, the shielding structure 6 includes a slide rail 601, which is fixedly connected to the body 1, and the inner wall of the slide rail 601 is slidably connected to a slider 602, the surface of the slider 602 is fixedly connected to a bending plate 603, the surface of the bending plate 603 is fixedly connected to a clamping plate 604, the surface of the clamping plate 604 is fixedly connected to a telescopic tube 605, a circular hole is opened on the surface of the slide rail 601, a screw 606 is threadedly connected to the surface of the slide rail 601, an end of the screw 606 away from the slide rail 601 is fixedly connected to a circular plate 607, and the screw 606 is threadedly connected to the slider 602.

[0031] When the shielding structure 6 is needed, the bending plate 603 is first pulled, and the bending plate 603 will drive the slider 602. At this time, the slider 602 moves to the specified position along the inner wall of the slide rail 601. When the slider 602 moves, it will also drive the slide bar 608. The slide bar 608 plays a role in assisting the movement of the slider 602, thereby preventing the slider 602 from positionally shifting during the movement. At this time, the bending plate 603 is continued to be pulled, and the bending plate 603 will also drive the card plate 604. The card plate 604 will drive the telescopic tube 605 until the telescopic tube 605 reaches the specified position and stops. At this time, the pulling frame 610 is pressed, and the pulling frame 610 will drive The telescopic tube 605 is telescopic and the pulling frame 610 facilitates the pulling and pressing of the telescopic tube 605 until the telescopic tube 605 completely covers the steel bar 5. The telescopic tube 605 can temporarily cover the steel bar 5. At this time, the rotating plate 612 is pressed, and the rotating plate 612 will drive the limit rod 611. The rotating plate 612 facilitates the pressing of the limit rod 611.

[0037] When the auxiliary structure 7 is needed, first pull the baffle 73, the baffle 73 will drive the moving block 72, and the moving block 72 will move to the specified position along the inner wall of the slide groove 71. When the baffle 73 moves, it will also drive the dustproof pad 74, and the dustproof pad 74 can quickly absorb the flying dust.
