When the multimeter 1 is used up and needs to be collected and sorted, first, the two data lines 6 are pulled out from the jacks 5, then the two test pens 7 are respectively clamped in the mounting grooves 83 on the two mounting blocks 82, and then the data lines 6 at one ends of the two test pens 7 are wound around the winding posts 84. After the winding is completed, the fixing plate 85 is rotated so that the fixing plate 85 contacts and presses on the test pens 7 and the data lines 6. Then the bolt 94 is threadedly connected to the mounting plate 81 until the bolt 94 is threadedly connected to the fixing plate 85. At this time, when the multimeter 1 is in use, it can be better collected and sorted, and the data lines 6 are not easily entangled and knotted, nor are the data lines 6 and the test pens 7 easily lost, which is convenient for the next use of the multimeter 1 and improves the working efficiency and use effect of the diode conduction test.

[0030] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in the figure, in this embodiment: A rotating handle 87 is fixedly connected to one side surface of the bolt 94. A number of anti-slip protrusions are provided on the surface of the rotating handle 87. Through the setting of the rotating handle 87, when the bolt 94 rotates to fix the fixing plate 85, it is more convenient and fast, improving the convenience of winding the data lines 6 and the test pens 7. A reinforcing plate 88 is fixedly connected to one side surface of the fixing plate 85. The reinforcing plate 88 is a rubber plate. Through the setting of the reinforcing plate 88, the contact friction between the fixing plate 85 and the data lines 6 and the test pens 7 is increased, and further improves the use effect of the fixing plate 85.

[0031] Refer to Figure 1 、 Figure 2 andFigure 3 As shown in the figure, in this embodiment: on one side of the winding post 84 on the surface of the mounting plate 81, a limiting plate 811 is fixedly connected. A number of uniformly distributed anti-slip stripes are provided on one side surface of the limiting plate 811. Through the arrangement of the limiting plate 811, when the data cable 6 is wound around the winding post 84, it is more firmly wound and not prone to loosening, improving the use effect of the fixing device 8.

[0034] Working principle: When the multimeter 1 is being collected and sorted after use, first pull out the two data lines 6 from the jack 5, then respectively snap the two test pens 7 into the mounting grooves 83 on the two mounting blocks 82, then wind the data lines 6 at one end of the two test pens 7 around the winding posts 84. After the winding is completed, rotate the fixing plate 85 so that the reinforcing plate 88 on one side of the fixing plate 85 contacts and presses on the test pen 7 and the data line 6.

[0035] When the multimeter 1 is stored idle, pull the operation block 93 to rotate the protection plate 92, so that the protection plate 92 rotates on the rotating shaft frame 91 until the protection plate 92 shields the surface of the jack 5. Then thread-connect the screw 86 to the multimeter 1 so that the screw 86 is engaged with the inner wall of the fixing groove 95 on the surface of the protection plate 92. At this time, when the multimeter 1 is stored idle, dust and impurities are not easily introduced into the jack 5, thus ensuring the stable insertion of the data line 6, so that the multimeter 1 can be used normally and conduct the diode conduction test efficiently and stably.
