[0004] However, during the storage process of the above detector, the following problems will occur:

[0005] Generally, there are two display screens on the detector. One is located on the handle and can be used by the user to select detection frequencies, detection methods, etc. The other is located on the detection head and can conveniently display the source and intensity of detection signals, etc. When storing the detector, since the display screen is a relatively fragile component, it is easily scratched, collided or damaged physically in other forms by other hard objects, resulting in scratches or even damage to the display screen. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1 - 5, a non-linear node detector, comprising a holding rod 1, a display screen 13 and a detection head 12 mounted at the front end of the holding rod 1. One end of the holding rod 1 close to the display screen 13 is connected with a support assembly, the other end of the support assembly is connected with a shielding cover 5, the bottom surfaces on both sides of the shielding cover 5 are connected with reset assemblies, the other ends of the two reset assemblies are both connected with a bottom cover 9, and the other ends of the two bottom covers 9 abut against each other. Among them, the detection head 12 is located inside the two bottom covers 9, the display screen 13 is located inside the shielding cover 5, and a limiting assembly is connected between the outer walls of the two bottom covers 9.

[0024] A non-linear node detector in the present utility model is similar in structure to the existing non-linear node detector, such as a non-linear node detector disclosed in the patent with the publication number CN212696110U. As Figures 1 to 5 shown, when folding the detection head 12 of the non-linear node detector in the present utility model for storing the entire detector, it is only necessary to rotate the shielding cover 5 towards the display screen 13 through the support assembly, and then through the two reset assemblies, rotate and merge the two bottom covers 9 towards the middle respectively, and then limit the position through the limiting assembly, so that the two bottom covers 9 will not unfold automatically. Furthermore, the display screen 13 and the detection head 12 can be protected by the shielding cover 5 and the two bottom covers 9. And because the two bottom covers 9 are limited by the limiting assembly and cannot unfold, the shielding cover 5 cannot unfold at this time either, so as to avoid external objects damaging the display screen 13 and the detection head 12 during storage. A power supply is provided inside both the display screen 13 and the detection head 12, and data is transmitted between the two through wireless communication; it can also be connected by wires, and the wires will not interfere with other structures; the above connections are all prior arts.

[0025] Please mainly refer to Figure 5 , the reset assembly includes an elastic component, two L-shaped blocks 6 and two rotating blocks 7. One ends of the two L-shaped blocks 6 are fixedly connected to the bottom surface of the shielding cover 5, the lower ends of the two rotating blocks 7 are fixedly connected to the upper end of the bottom cover 9, and the adjacent ends of the two L-shaped blocks 6 and the two rotating blocks 7 are sleeved on the outer wall of the elastic component.

[0026] More specifically, the reset assembly is provided, so that when normal detection needs to be carried out through the detection head 12, it is only necessary to loosen the limiting assembly. At this time, the two bottom covers 9 can automatically unfold to both sides under the action of the two reset assemblies, thus saving the time for rotating and opening the bottom cover 9.

[0027] The specific steps are as follows: when the limiting assembly is loosened, the elastic component lacks the limiting pressure at this time, and thus can apply a thrust to both the shielding cover 5 and the bottom cover 9 at the same time. Furthermore, the bottom cover 9 can rotate with the elastic component as the axis, so that the bottom cover 9 rotates and opens.

[0028] Please mainly refer to Figure 5, the elastic component includes a rotating shaft 16 and a torsion spring 8. The rotating shaft 16 passes through the torsion spring 8, two L-shaped blocks 6 and two rotating blocks 7. The outer wall of the rotating shaft 16 is fixedly connected to the inner walls of the two L-shaped blocks 6, and the outer wall of the rotating shaft 16 is rotatably connected to the inner walls of the two rotating blocks 7. The two ends of the torsion spring 8 are respectively fixedly connected to the side walls of the shielding cover 5 and the bottom cover 9.

[0029] More specifically, when protecting the display screen 13 and the detection head 12, due to the action of the limiting component at this time, the two bottom covers 9 are pressed against each other, and at this time the torsion spring 8 is compressed. When the limiting component is released, since the torsion spring 8 lacks external pressure at this time, it can, according to its own characteristics, rotate and open the bottom cover 9 towards the shielding cover 5 with the rotating shaft 16 as the axis. After that, just rotate the shielding cover 5 towards the holding rod 1 to expose the display screen 13 and then normal detection can be carried out.

[0030] Please mainly refer to Figure 1 , Figure 3 and Figure 4 , the support component includes a support ring 2, a connecting block 4 and a U-shaped support rod 3. The support ring 2 is sleeved and fixedly connected to the outer wall of the holding rod 1 near one end of the display screen 13. The two ends of the U-shaped support rod 3 are respectively fixedly connected to the two sides of the outer wall of the support ring 2. One end of the connecting block 4 is sleeved and rotatably connected to the middle of the U-shaped support rod 3, and the other end of the connecting block 4 is fixedly connected to the outer wall of the shielding cover 5.

[0031] More specifically, by setting the support component, a supporting force can be provided for the shielding cover 5, the bottom cover 9, etc.

[0032] The specific steps are as follows: Supported by the support ring 2 and the U-shaped support rod 3, when the shielding cover 5 needs to be rotated, just rotate it to one side, that is, the shielding cover 5 can be opened with the connecting block 4 sleeved in the middle of the U-shaped support rod 3 as the axis.

[0033] Please mainly refer to Figure 2 , Figure 3 and Figure 5 , sponge pads 14 are fixedly connected to the inner side walls of the shielding cover 5 and the two bottom covers 9.

[0034] More specifically, by setting the sponge pads 14, it can be avoided that the inner side walls of the shielding cover 5 and the bottom cover 9 rub against the surfaces of the display screen 13 and the detection head 12.

[0035] Please mainly refer to Figure 5 , the limiting component includes a first magic tape 10 and a second magic tape 15. The outer wall of one of the bottom covers 9 is fixedly connected to the second magic tape 15, and the outer wall of the other bottom cover 9 is fixedly connected to one end of the first magic tape 10. The other end of the first magic tape 10 surrounds the two bottom covers 9 and is bonded to the second magic tape 15.

[0036] More specifically, when it is necessary to limit the positions of two bottom covers 9, after the two bottom covers 9 are combined, just bypass the first magic tape 10 from below the two bottom covers 9 and stick it on the second magic tape 15 of the other bottom cover 9, which is convenient and easy to operate.

[0037] Please refer mainly to Figure 1 and Figure 5 , magnets 11 are fixedly connected to the outer walls of both the shielding cover 5 and the holding rod 1, and the two magnets 11 attract each other.

[0038] More specifically, by setting the magnets 11, after the shielding cover 5 is rotated and opened to one side, the shielding cover 5 can be stood on the holding rod 1 by the magnets 11, preventing the shielding cover 5 from rotating back by itself during normal detection.

[0039] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
