The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1, reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a novel voltage level selectable electroscope, the device comprises a switching mechanism 100, including a protection box 101, a lifting part 102 arranged inside the protection box 101, a positioning part 103 arranged on the lifting part 102, a switching part 104 arranged on the lifting part 102 and the positioning part 103, a pressing part 105 arranged on the protection box 101 and the switching part 104, and a measuring part 106 arranged on the switching part 104 and the protection box 101;

[0034] The quick release mechanism 200 includes a threaded interface 201 which is disposed on the outer shell of the protective box 101 and is away from the lifting part 102 .

[0035] One end of the switching part 104 is connected to the input interface of the measuring part 106 , and the other end is connected to the lifting part 102 . A positioning part 103 is provided inside the lifting part 102 . The switching part 104 and the pressing part 105 are slidably connected.

[0036] When in use, the switching part 104 drives the input ports of the lifting part 102 and the measuring part 106 to rise or fall at the same time, so that the input port of the measuring part 106 is close to different voltage measurement modules according to actual needs, so that the voltage level measured by the electroscope can be switched, which is convenient to use and reduces the operation difficulty and use cost. When the required measurement voltage range is selected, the squeezing part 105 drives the switching part 104 and the measuring part 106 to move back and forth and automatically insert into the voltage measurement module. At the same time, the positioning part 103 fixes the lifting part 102 and the measuring part 106 to prevent the measuring part 106 from being displaced and affecting the normal use of the electroscope. In addition, the thread 202 set on the measuring part 106 can be threadedly connected with the threaded interface 201 on the protective box 101, so that the measuring part 106 can be quickly disassembled for convenient and quick use.

[0037] Example 2, reference Figure 2 to Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the lifting part 102 includes a lifting guide rail 102a arranged inside the protective box 101, and a lifting bracket 102b arranged on the lifting guide rail 102a.

[0039] Furthermore, the switching part 104 includes a connecting rod 104a arranged on the lifting bracket 102b, the connecting rod 104a is arranged in three pieces, a fixing plate 104b arranged on the connecting rod 104a, a switching paddle 104c arranged at the other end of the connecting rod 104a, and a limiting groove 103f arranged on the outer shell of the protective box 101, the limiting groove 103f is adapted to the connecting rod 104a, and the switching paddle 104c is located on the outside of the protective box 101.

[0040] Furthermore, the pressing portion 105 includes a second spring 105a disposed on the connecting rod 104a, and the second spring 105a is slidably connected to the connecting rod 104a.

[0041] Furthermore, the measuring part 106 includes an adapter socket 106a arranged on the fixed plate 104b and away from the side of the connecting rod 104a, a voltage measuring module 106b arranged on the protective box 101, a telescopic rod 107 arranged on the top of the protective box 101, and a voltage contact 106c arranged on the telescopic rod 107. The voltage contact 106c and the adapter socket 106a are electrically connected through a spring cable 106d.

[0042] Furthermore, two matching through holes 104d are correspondingly provided on the lifting bracket 102b near the middle connecting rod 104a, and the connecting rod 104a is slidably connected in the through holes 104d.

[0043] Among them, the lifting bracket 102b is slidably connected on the lifting guide rail 102a and performs vertical lifting movement. The number of positioning grooves 103a is set to two, and the number of extrusion plates 103c inside each positioning groove 103a is set to two, and a plurality of first springs 103d are arranged between the two extrusion plates 103c. The extrusion plates 103c are slidably connected in the positioning grooves 103a, and the positioning blocks 103b are slidably connected in the positioning through holes 103e. Three positioning holes 103f are arranged in each row from top to bottom, and The position corresponds to the voltage measuring module 106b, the limiting groove 103f is set to three, and each limiting groove 103f is slidably connected to a connecting rod 104a, the second spring 105a is set to two, which are respectively installed on the two outermost connecting rods 104a, and one end of the second spring 105a is against the fixing plate 104b, and the other end is against the inner wall of the protection box 101, and the voltage measuring module 106b is set on the shell of the protection box 101 away from the switching paddle 104c.

[0044] When in use, by switching the paddle 104c and the three connecting rods 104a, the adapter socket 106 on the other side of the fixed plate 104b is driven to move up and down. At the same time, three height-inconsistent positioning holes 103f are opened on the lifting guide rail 102a, and the three positioning holes 103f and the positions correspond to the three voltage measuring modules 106b. Therefore, when the lifting bracket 102b drives the adapter socket 106a to move to the corresponding voltage measuring module 106b, the two extrusion plates 103c inside the positioning groove 103a are squeezed by the multiple first springs 103d, so that the positioning block 103b extends out from the positioning through hole 103e, and the positioning block 103b is stuck in the positioning hole 103f opened on the lifting guide rail 102a, thereby moving the positioning grooves 103a, The lifting bracket 102b and the adapter socket 106a are fixed, and at the same time, the second spring 105a applies pressure to the fixed plate 104b, so that the adapter socket 106a is inserted into the input interface of the voltage measuring module 106b, so that the position of the conversion interface 106a can be switched at will, and different voltage measuring modules 106b can be switched according to actual needs, so that the electrical testing measurements of multiple voltage levels can be taken into account at the same time, which not only simplifies the operation difficulty, but also reduces the cost of electrical testing. In addition, among the three connecting rods 104a, the middle connecting rod 104a is slidably connected to the through hole 104d on the inner side of the lifting bracket 102b, so that when the connecting rod 104a moves horizontally, it will not drive the lifting bracket 102b to move horizontally, thereby causing interference with the movement of the connecting rod 104b.

[0045] Example 3, reference Figure 8-Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a thread 202 is provided on the voltage measuring module 106b.

[0046] Furthermore, the telescopic rod 107 is provided with a fixing hole 108 , and a fixing bolt 109 is inserted into the fixing hole 108 .

[0047] Furthermore, a handle 110 is fixed to one end of the protective box 101 away from the telescopic rod 107 , and the handle 110 is covered with a magic sticker 111 .

[0048] There are three voltage measurement modules 106 b, which are vertically distributed up and down. The voltage measurement module threads 202 are matched with the threaded interface 201 . Each section of the telescopic rod 107 is provided with a plurality of equidistant fixing holes 108 .

[0049] When in use, a thread 202 is provided on the voltage measuring module 106b, and three threaded interfaces 201 are correspondingly installed on the protective box 101. Therefore, the voltage measuring module 106b can be quickly disassembled through the threaded connection between the two, so that the user can quickly replace the voltage measuring module 106b with different low voltages for electrical testing according to usage requirements, which greatly improves the practicality of the electrical tester. In addition, telescopic rods 107 and handles 110 are respectively installed at the upper and lower ends of the protective box 101. Corresponding fixing holes 108 with the same distance are provided on each level of the telescopic rod 107, which are matched with matching fixing bolts 109, and then the appropriate working length can be selected according to actual needs.
