[0024] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale.

[0025] Example 1
[0026] Reference Figures 1 to 4 , this embodiment provides a loop auxiliary verification structure, including,
[0027] The housing 100 is provided with a first slot 101 and a second slot 102 . A first side slot 101 a is provided on the left side of the first slot 101 , and a second side slot 102 a is provided on the right side of the second slot 102 .
[0028] It should be noted that the first slot 101 and the second slot 102 are used to electrically connect to a conductive test lead or a conductive test clamp. Since the existing test leads are one red and the other black, and the positive and negative poles are distinguished only by color, sometimes the wrong insertion occurs. Under certain detection items, the reverse connection of the positive and negative poles will cause the equipment to burn. In order to avoid this situation, the structure of the first slot 101 and the second slot 102 is adjusted so that the first slot 101 and the second slot 102 are chirally symmetrical, so that under normal use, the test lead can only be connected to its corresponding slot.
[0029] Furthermore, it also includes a first test lead 201, which is provided with a first insulating head 201a, a first holding rod 201b is provided on the side of the first insulating head 201a, a first conductive ring piece 201c is provided at one end of the first holding rod 201b, and a first side block 201d is provided on the left side of the first conductive ring piece 201c.
[0030] The first test lead 200 is black, and a black mark is painted in the first side groove 101 a.
[0031] The second test lead 202 is provided with a second insulating head 202a, a second holding rod 202b is provided on the side of the second insulating head 202a, a second conductive ring piece 202c is provided at one end of the second holding rod 202b, and a second side block 202d is provided on the right side of the second conductive ring piece 202c.
[0032] The second test lead 300 is red, and a red mark is painted in the second side groove 102 a.
[0033] The first test lead 202 is inserted into the first slot 101, and the second test lead 202 is inserted into the second slot 102. Under normal circumstances, when taking the first test lead 202 and the second test lead 202 for plugging, the first holding rod 201b and the second holding rod 202b must be taken for convenience, and the loop auxiliary detection structure as a whole is also held upright. Therefore, in this state, the first insulating head 201a cannot be inserted into the second slot 102, and can only be inserted into the first slot 101, thereby avoiding the situation of reverse insertion.
[0034] A first annular groove 201 e is provided at the other end of the first test lead 201 , and a second annular groove 202 e is provided at the other end of the second test lead 202 .
[0035] The structure of the first annular groove 201e corresponds to the combined structure of the first insertion slot 101 and the first side groove 101a; and the structure of the second annular groove 202e corresponds to the combined structure of the second insertion slot 102 and the second side groove 102a.
[0036] The housing 100 is provided with a connecting bar 103 , and a dust cover 104 is connected to the connecting bar 103 . The dust cover 104 has a dust plug 105 provided on one side thereof.
[0037] It should be noted that the structures of the connecting strip 103, the dust cover 104 and the dust plug 105 are also provided in two groups, which correspond to the structures of the first slot 101 and the second slot 102 respectively. When the verification structure is not in use, the dust covers 104 are respectively plugged in the first slot 101 and the second slot 102 for dust prevention. When the verification structure is in use, the first test lead 200 and the second test lead 300 are respectively inserted into the first slot 101 and the second slot 102. At this time, dust plugs are correspondingly embedded in the first annular groove 201e and the second annular groove 202e to play a fixing role.
[0038] The housing 100 is also provided with a display screen 300 , a knob 400 and a button 500 .
[0039] The display screen 300 is used to display information, the knob 400 and the button 500 are used for adjustment, and a processing module is set inside the shell 100. The display screen 300, the knob 400 and the button 500 are connected to the processing module. The processing module adopts existing technology and is used for electrical measurement, which will not be repeated here.
[0040] A battery box 106 and a movable bracket 107 are provided at the bottom of the housing 100. The movable bracket 107 is hingedly connected to the housing 100 and can support the housing 100 when unfolded.
[0041] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
