DETAILED DESCRIPTION

[0022] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-3 The present invention provides a technical solution: a power safety IoT capacitive tester, comprising a tester circuit box 1, an insulating operating rod 2 and a handle 3, such as Figure 1 As shown, the electroscope circuit box body 1 is provided with a detection probe 4 and a display screen 5. Figure 2As shown, the electroscope circuit box body 1 includes a microcontroller module 6 and a self-test circuit module 7. The electroscope circuit box 1 is responsible for the detection function. During the detection, the detection probe 4 is brought into contact with the device to be detected, so that the detection result is displayed on the display screen 5. The insulating operating rod 2 includes a first sleeve 201, a second sleeve 202 and a third sleeve 203. The first sleeve 201, the second sleeve 202 and the third sleeve 203 are all tubular. The first sleeve 201, the second sleeve 202 and the third sleeve 203 are plug-in. The first sleeve 201, the second sleeve 202 and the third sleeve 203 can slide freely between them, so that the length of the insulating operating rod 2 can be changed, and the first sleeve 201, the second sleeve 202 and the diameter of the third sleeve 203 decreases successively. The handle 3 is fixed on the first sleeve 201. The handle 3 is also tubular, and an anti-slip cover can be provided on its outer surface for easy holding. A secondary display screen 8 is provided on the outer surface of the handle 3. The secondary display screen 8 is electrically connected to the display screen 5. The secondary display screen 8 can display the same content as the display screen 5. Therefore, when the insulating operating rod 2 is extended, the detection result can be observed by observing the secondary display screen 8. The first sleeve 201 and the second sleeve 202 are respectively provided with fastening devices 9. The fastening devices can fix the relative positions between the first sleeve 201, the second sleeve 202 and the third sleeve 203, thereby fixing the length of the insulating operating rod 2.

[0025] Specifically, if Figure 2 As shown, the fastening device 9 is a fastening bolt, which passes through the side walls of the first sleeve 201 and the second sleeve 202, and is threadedly connected to the first sleeve 201 and the second sleeve 202 respectively. When the fastening device 9 is tightened, the fastening device 9 is in close contact with the outer surfaces of the second sleeve 202 and the third sleeve 203 respectively, thereby fixing the relative positions of the first sleeve 201, the second sleeve 202 and the third sleeve 203.

[0026] Specifically, the fastening devices 9 are respectively located at one end of the first sleeve 201 and the second sleeve 202 away from the handle 3, so that when sliding between the first sleeve 201, the second sleeve 202 and the third sleeve 203, even if the sliding distance is relatively long, the fastening devices 9 can still play a role in fixing the relative positions between the first sleeve 201, the second sleeve 202 and the third sleeve 203.

[0027] Specifically, the auxiliary display screen 8 is connected to the display screen 5 via a wire 10 .

[0028] Specifically, a wire reel 11 is provided inside the insulating operating rod 2. Figure 3As shown, the wire reel 11 includes a shell 1101, and the shell 1101 is a closed cavity. Both ends of the shell 1101 are respectively provided with a first through hole 1102, and the diameter of the first through hole 1102 is slightly larger than the diameter of the wire 10. The inner wall of the shell 1101 is rotatably connected to a winding roller 1103, and a second through hole 1104 is penetrated at the center of the winding roller 1103, and the second through hole 1104 is arranged in the same direction as the axis of the insulating operating rod 2. A torsion spring is provided between the winding roller 1103 and the shell 1101, and the wire 10 passes through the first through hole 1102 and the second through hole 1104 respectively. Under the action of the torsion spring, the winding roller 1103 winds the wire 10 on its surface. When the insulating operating rod 2 is extended, the wire 10 pulls the winding roller 1103 to rotate, so as to prevent the wire 10 from being repeatedly bent and broken when the insulating operating rod 2 is repeatedly extended and shortened.

[0029] Working principle: When the present invention is in use, the fastening device 9 is rotated to loosen the fastening device 9, and then the insulating operating rod 2 can be stretched at will, that is, the first sleeve 201, the second sleeve 202 and the third sleeve 203 can slide relative to each other, thereby changing the length of the insulating operating rod 2. After adjusting the appropriate length, the fastening device 9 is screwed to fix the relative positions of the first sleeve 201, the second sleeve 202 and the third sleeve 203, so that the length of the insulating operating rod 2 is fixed, and then the detection probe 4 is brought into contact with the device to be tested to perform detection, the display screen 5 will display the detection result, and then the electrical signal will be simultaneously transmitted to the auxiliary display screen 8 through the wire 10, so that the staff can observe the detection result conveniently.

[0030] Example 2

[0031] See also Figure 4-5 The difference between this embodiment and embodiment 1 is that: the outer walls of the second sleeve 202 and the third sleeve 203 are respectively provided with sliders 12, and the inner walls of the first sleeve 201 and the second sleeve 202 are provided with sliding grooves 13 corresponding to the sliding grooves 12, and the sliding grooves 13 are arranged parallel to the axis of the insulating operating rod 2, so that the first sleeve 201, the second sleeve 202 and the third sleeve 203 will not rotate when they slide relative to each other.

[0032] Specifically, the fastening device 9 includes a sleeve 14, which is rotatably connected to the first sleeve 201 and the second sleeve 202 at one end away from the handle 3, and the sleeve 14 is coaxially arranged with the insulating operating rod 2. The inner wall of the sleeve 14 is provided with an internal thread, and the outer walls of the second sleeve 202 and the third sleeve 203 are respectively provided with external threads engaged with the sleeve 14. When the sleeve 14 is rotated, the first sleeve 201 and the second sleeve 202 are driven to slide through the threaded cooperation, thereby changing the length of the insulating operating rod 2. While facilitating adjustment, there is no need to lock after adjustment, and the operation is more convenient.

[0033] Specifically, the slider 12 is respectively located at one end of the second sleeve 202 and the third sleeve 203 close to the handle 3, so that the sliding distance of the first sleeve 201, the second sleeve 202 and the third sleeve 203 is longer and the adjustment stroke is larger.

[0034] Specifically, the auxiliary display screen 8 and the display screen 5 are connected by a conductive rail 15, and the conductive rail 15 is respectively arranged on the inner wall of the slide groove 13. When the first sleeve 201, the second sleeve 202 and the third sleeve 203 are sliding, the slider 12 is always located inside the slide groove 13. After the conductive rail 15 is arranged on the inner wall of the slide groove 13, the electrical connection between the auxiliary display screen 8 and the display screen 5 can be achieved by arranging a wire on the slider 12 to contact the conductive rail 15.
