[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0027] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] Example 1

[0029] like Figure 1-4 As shown, the utility model provides a technical solution: a portable high-voltage line tester, comprising: a portable mechanism 1, a protective mechanism 2 is arranged on one side of the portable mechanism 1, the portable mechanism 1 comprises an instrument body 11, a slide groove 12 is provided inside the instrument body 11, a vertical rod 13 is provided on the inner surface of the slide groove 12, a horizontal plate 15 is provided on one side of the vertical rod 13, a screw rod 16 is arranged inside the horizontal plate 15, one end of the screw rod 16 is rotatably connected to one end of the side of the horizontal plate 15, and the slide groove 12 is provided with a vertical rod 13. A limit rod 14 is provided on the inner surface, a vertical rod 13 is provided on the outer side of the limit rod 14, an insertion rod 18 is provided inside the vertical rod 13, an instrument body 11 is provided at one end of the insertion rod 18, a recessed hole 17 is provided inside the instrument body 11, a connecting plate 19 is provided at one end of the insertion rod 18, a fixing rod 110 is provided on one side of the instrument body 11, a strap 111 is provided on the outer side of the fixing rod 110, a wear sticker is provided on one side of the strap 111, and the instrument body 11 is provided at one end of the strap 111.

[0030] In this embodiment, in order to prevent the high-voltage tester from being tested in a gripping manner during the test, the connecting plate 19 is dragged to one side so that the plug rod 18 releases the fixation of the vertical rod 13. At this time, the vertical rod 13 is pulled out from the bottom of the instrument body 11 so that the vertical rod 13 is extended. Subsequently, the two vertical rods 13 are brought close to the fixed object. At this time, the screw rod 16 on the horizontal plate 15 is rotated. During the rotation process, the two vertical rods 13 will gradually contact the fixed object and be fixed to the fixed object. Therefore, the instrument body 11 does not need to be tested in a handheld manner during use, which can reduce the shaking or instability caused by hand-holding, thereby making the test process more reliable and accurate, and reducing the accidental risks caused by hand-held operation.

[0031] Secondly, when the instrument body 11 is not in use, in order to prevent the instrument body 11 from falling off due to loosening, the palm is passed through the strap 111, and then the strap 111 is tightened on the fixing rod 110. The strap 111 is installed with a Velcro 112. After being tightened, the Velcro 112 can always keep the strap 111 in a tight state, thereby ensuring that the instrument body 11 will not fall off the palm, reducing the probability of damage to the instrument body 11, and increasing the stability and reliability of use.

[0032] Example 2

[0033] like Figure 1-4 As shown, the protection mechanism 2 includes a folding plate 21 , one side of the folding plate 21 is fixedly connected to one end of a spring 22 , and the other end of the spring 22 is fixedly connected to the inner wall of the instrument body 11 .

[0034] In this embodiment, a folding plate 21 is installed in the direction of the display screen of the instrument body 11, and a spring 22 is designed on one side of the folding plate 21. The folding plate 21 can serve as a protective layer when the instrument falls to reduce direct impact and scratches and reduce the possibility of damage to the display screen. The design of the spring 22 can absorb part of the impact force generated when falling, reduce the impact on the internal electronic components and display screen of the instrument, and thus reduce the possibility of damage.

[0035] Working principle:

[0036] like Figure 1-4 As shown, by dragging the connecting plate 19 to one side, the insertion rod 18 releases the fixation of the vertical rod 13. At this time, the vertical rod 13 is pulled out from the bottom of the instrument body 11 to extend the vertical rod 13. Subsequently, the two vertical rods 13 are brought close to the fixed object. At this time, the screw rod 16 on the horizontal plate 15 is rotated. During the rotation process, the two vertical rods 13 will gradually contact with the fixed object and be fixed to the fixed object, so that the instrument body 11 does not need to be tested in a handheld manner during use. Secondly, the palm position is passed through the strap 111, and then the strap 111 is tightened on the fixed rod 110. The strap 111 is installed with Velcro 112. After tightening, the Velcro 112 can always keep it in a tight state, thereby ensuring that the instrument body 11 will not fall off the palm and reducing the probability of damage to the instrument body 11.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0038] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
