The tester can be used in the following voltage levels: 6kV, 10kV, 35kV, 110kV, 220kV, 330kV, and 500kV AC voltage. Each voltage level is equipped with a tester of the corresponding voltage level.

[0003] Usually, the telescopic rod of a handheld electrometer is pulled out, and the testing part of the detection part is brought close to the area to be tested. When there is electricity in the tested area, an audible and visual alarm will be issued. A protective pad is provided at the front of the grip to prevent the hand from contacting the telescopic rod and causing electric shock.

[0004] However, during actual use, the hand may come into contact with the telescopic rod due to loss of strength or panic caused by excessive concentration, resulting in electric shock.

[0005] Based on this, it is necessary to propose a portable electroscope that can reduce the risk of electric shock caused by the hand moving toward the telescopic rod and contacting it. Utility Model Content

[0006] The purpose of the present utility model is to provide a portable electroscope to solve the above technical problems to at least a certain extent, so as to keep the hand in the gripping part, reduce the contact between the hand and the telescopic rod, and reduce the risk of electric shock.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-3 The utility model provides a technical solution: a portable electroscope, including a detection unit 100, an insulating unit 200 and a limiting unit 300. The detection unit 100 is an electric power detection part and is connected to the insulating unit 200. The detection unit 100 is a conventional electroscope equipped with an audible and visual alarm device, which will not be described in detail here. The insulating unit 200 and the limiting unit 300 are both rubber insulators.

[0031] The rubber-like settings of the insulating unit 200 and the limiting unit 300 can increase resistance, reduce current conduction, and prevent current from being conducted to the hand and causing clicking. In addition, the rubber-like settings of various components can reduce mutual wear and damage during use and extend the service life.

[0032] See Figure 1In a preferred embodiment, the insulating unit 200 includes a telescopic rod 210 connected to the detection unit 100, the telescopic rod 210 is insulated and connected parallel to the bottom of the detection unit 100, and the connection between the telescopic rod 210 and the detection unit 100 is surrounded by an annular sleeve.

[0033] The telescopic rod 210 is connected in parallel to the detection unit 100, which can maintain the pointing direction of the telescopic rod 210, that is, the pointing direction of the detection unit 100, without any angle deviation or detection position offset, and the connection between the two components is surrounded by an insulating ring sleeve to effectively prevent other objects from accidentally touching and causing an impact.

[0034] See Figure 3 In a further preferred embodiment, the end of the telescopic rod 210 away from the detection unit 100 is a gripping handle 220, and the outside of the gripping handle 220 is sleeved with an insulating sleeve 221. The end of the insulating sleeve 221 near the telescopic rod 210 is provided with a protective pad 2211 larger than the side area of ​​the insulating sleeve 221. The gripping handle 220 can be sleeved with the insulating sleeve 221 after being coated with glue, and the protective pad 2211 and the insulating sleeve 221 are integrally arranged on the gripping handle 220.

[0035] The insulating sleeve 221 can reduce the current transmitted to the telescopic rod 210 and move to the gripping handle 220, thereby reducing the contact between the current and the human body. The insulating protective pad 2211 can further slide the base of the palm forward, thereby reducing the forward sliding of the base of the palm onto the telescopic rod 210 to a certain extent. The insulating sleeve 221 can be coated with glue inside and then put on the gripping handle 220, thereby effectively improving the tightness of the connection between the insulating sleeve 221 and the gripping handle 220 and fully and effectively reducing the possibility of the insulating sleeve 221 falling off.

[0036] See Figure 1 In a preferred embodiment, the limiting unit 300 includes a limiting rod 310 integrally connected to the insulating sleeve 221, the limiting rod 310 passes through the limiting frame 330 outside the gripping handle 220, and is limited by the insulating hexagonal nut 320 outside the limiting rod 310, the limiting rod 310 is symmetrically installed on the insulating sleeve 221 and passes through the limiting frame 330 through the positioning holes on the limiting frame 330, the inner wall of the limiting frame 330 is rounded, and the upper and lower parts of the limiting frame 330 are both open.

[0037] The limit rods 310 on both sides of the insulating sleeve 221 pass through the limit frame 330, and are connected to the limit rods 310 through the insulating hexagonal nuts 320, so as to keep the limit frame 330 connected to the insulating sleeve 221 sleeved on the gripping handle 220. The frame-shaped setting of the limit frame 330 can keep the gripping handle 220 in it, and the positioning hole and the limit rod 310 allow the limit frame 330 to rotate to a certain angle. The limit frame 330 can be adjusted as needed in various situations. When the hand is in the limit frame 330, its rounded corner setting can effectively prevent greater wear and tear on the skin. Its softness that fits the skin better reduces damage. The opening setting of the limit frame 330 can effectively allow the palm to be in the limit frame 330 for gripping, preventing the hand from being squeezed too much due to too small a space.

[0038] See Figure 1 Preferably, the inner wall of the limit frame 330 is symmetrically connected to the limit ring 340, and the limit ring 340 is located on both sides below the gripping handle 220. The limit ring 340 is set as a through opening from top to bottom, and the corners of the limit ring 340 are rounded.

[0039] When the palm is on the gripping handle 220, the fingers bend downward and enter the finger limit ring 340, wherein the fingers hook the finger limit ring 340, and a force toward the palm can be applied to the finger limit ring 340, that is, forces are applied to the gripping handle 220 and the finger limit ring 340 from above and below respectively to grasp, and the rounded corner setting of the finger limit ring 340 can reduce wear on the skin, thereby reducing discomfort.

[0040] See Figure 1 In a preferred embodiment, a positioning opening 331 is provided on the side of the limiting frame 330 , and the corners of the positioning opening 331 are rounded.

[0041] When the hand is in a grasping state in the limit frame 330, the back of the hand and the hand bones are in the positioning hole 331 of the limit frame 330 and contact with its outer wall to generate friction. The rounded corner setting of the positioning hole 331 can reduce the interaction force directly generated on the hand, effectively reduce the point-to-surface force on the back of the hand, and can provide an upward supporting force for the limit frame 330, reducing the force that the fingers need to apply to the limit ring 340 when grasping, thereby improving the comfort when grasping.

[0042] See Figure 1 Preferably, the limiting frame 330 is provided with a bracket 350 near one end of the telescopic rod 210 and at the front end of the insulating sleeve, and the bracket 350 is an arc-shaped setting with a notch facing upward.

[0043] The telescopic rod 210 needs to be checked for cracks when in use to prevent dangerous behaviors such as leakage. The arc-shaped setting of the bracket 350 can effectively reduce and increase the contact area with the telescopic rod 210, effectively reduce the friction on the telescopic rod 210, and reduce the wear and tear on the telescopic rod 210.
