[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a convenient DC resistance rapid tester, comprising a box body 1, the inner wall of the box body 1 is provided with a mainframe outer shell 2, the interior of the mainframe outer shell 2 is provided with a wire storage bin 3, the interior of the mainframe outer shell 2 is rotatably connected with a rotating rod 7, the outer wall of the rotating rod 7 is fixedly connected with a rotating sleeve 5, the outer wall of the rotating sleeve 5 is fixedly connected with a rotating block 4, the outer wall of the rotating block 4 is slidably connected to the interior of the mainframe outer shell 2, the outer wall of the rotating sleeve 5 is fixedly connected with an arc-shaped toothed plate 6, the outer wall of the rotating rod 7 is sleeved with a torsion spring 8, one end of the torsion spring 8 is fixedly connected to the interior of the mainframe outer shell 2, the other end of the torsion spring 8 is fixedly connected to the inner wall of the rotating sleeve 5, the interior of the rotating block 4 is fixedly connected with a telescopic rod 9, the outer wall of the telescopic rod 9 is sleeved with a telescopic spring 10, one end of the telescopic spring 10 is fixedly connected to the interior of the rotating block 4, the other end of the telescopic spring 10 is fixedly connected to a limiting block 11, the outer wall of the limiting block 11 is slidably connected to the interior of the mainframe outer shell 2, and a storage component is provided inside the mainframe outer shell 2;

[0023] Specifically, first, place the lead on the limit block 11 and press it down lightly. The limit block 11 will slide to both sides after being pressed, and will be closely connected to the rotating block 4 through the telescopic rod 9. When the limit block 11 slides, it will drive the rotating block 4 to rotate inside the main housing 2 with the rotating sleeve 5 as the center. When the rotating block 4 rotates, it will drive the arc-shaped toothed plate 6 and the torsion spring 8 to rotate together. The arc-shaped toothed plate 6 here plays a key role, so that when the arc-shaped toothed plate 6 on one side rotates, the arc-shaped toothed plate 6 on the other side will also rotate synchronously, so that the arc-shaped toothed plate 6 on both sides can rotate synchronously. The limit block 11 can maintain a consistent rotation speed and direction. When the lead completely passes over the limit block 11, the torsion spring 8 that was previously reversed will rebound quickly and return to its original state, driving the two limit blocks 11 to fit tightly together again, thereby effectively preventing the lead from moving out from between the limit blocks 11. Then, the limit block 11 and the rotating block 4 are pulled closer together through the telescopic spring 10, so that the limit block 11 can better clamp multiple leads to prevent them from moving at will. If the leads are frequently rubbed during storage, their service life will be seriously affected.

[0024] Reference Figure 1 and Figure 2The storage component includes a storage bin 12, the storage bin 12 is opened inside the mainframe outer shell 2, a handle 13 is fixedly connected to the upper surface of the mainframe outer shell 2, a terminal 14 is fixedly connected to the upper surface of the mainframe outer shell 2, a rotating shaft 15 is fixedly connected to the outer wall of the box body 1, a sealing box body 16 is fixedly connected to the outer wall of the rotating shaft 15, four anti-collision blocks 17 are fixedly connected to the outer wall of the sealing box body 16, a handle 21 is fixedly connected to the upper surface of the sealing box body 16, a buckle 18 is fixedly connected to the outer wall of the buckle 18, a plurality of ventilation holes 19 are opened inside the mainframe outer shell 2, a plurality of filters 20 are fixedly connected to the inside of the mainframe outer shell 2, a sealing ring 22 is fixedly connected to the upper surface of the mainframe outer shell 2, and the sealing ring 22 fits the box body 1;

[0025] Specifically, firstly, various tools and accessories required for testing can be neatly placed in the storage bin 12. Secondly, in order to facilitate users to conduct regular inspection and maintenance of the equipment, the storage bin 12 is designed with a convenient handle 13, which can easily pull the equipment body out of the box body 1. In addition, the sealed box body 16 and the box body 1 are cleverly combined with the hinge 15 through the buckle 18, so that users can easily open and close the box body, effectively preventing the invasion of dust and other impurities. The main body outer shell 2 is equipped with ventilation holes 19 and filter screen 20. The ventilation holes 19 can effectively introduce external air into the equipment, while the filter screen 20 can prevent dust and other impurities from entering the equipment, ensuring the cleanliness of the internal air. The equipment can maintain a stable operating temperature during the test, thereby improving the reliability and stability of the equipment. Finally, the handle 21 allows users to feel comfortable and stable when carrying the equipment.

[0026] Working principle: When you need to use the convenient DC resistance fast tester, you can first put the used lead on the limit block 11 and press down. At this time, the limit block 11 slides to both sides under the pressure, thereby driving the rotating block 4 to rotate inside the main body shell 2 with the rotating sleeve 5 as the center through the telescopic rod 9, and then driving the arc-shaped toothed plate 6 and the torsion spring 8 to rotate. The rotation of the arc-shaped toothed plate 6 drives the arc-shaped toothed plate 6 on the other side to rotate synchronously, so that the limit blocks 11 on both sides rotate synchronously. When the lead passes over the limit block 11, the torsion spring 8 is no longer subjected to force and rebounds, thereby driving the two limit blocks 11 to fit again. , prevent the lead from moving out, and then the limit block 11 and the rotating block 4 can be pulled closer by the extension and contraction of the telescopic spring 10, so that multiple leads can be clamped to prevent the leads from moving at will, causing friction to reduce the service life of the leads, and then the tools needed for testing can be placed inside the storage bin 12, and the main body can be pulled out through the handle 13 for easy maintenance, and then the sealed box body 16 can be opened and closed through the buckle 18 and the rotating shaft 15, and the interior of the main unit outer shell 2 is filled with clean air for heat dissipation through the cooperation of the ventilation hole 19 and the filter 20, and finally the box body can be conveniently carried through the handle 21.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
