[0042] To dismantle low-voltage household lines, the cables are directly cut through equipment for removal. However, in places where the circuits are more complicated, workers need to pass through multiple layers of low-voltage lines to dismantle them. During the removal process, they all use handheld tools. This method of removal poses a great safety hazard. If workers are electrocuted during the removal process, there is a risk of falling from the air.

[0043] In view of this, the present embodiment provides a wire cutter 100, a tester 200 and a cable cutting tool 300. The wire cutter 100 can prevent an operator from touching the cable when cutting the cable.

[0044] See also Figure 1 , a wire cutter 100, comprising: a connecting plate 10, a driving assembly 20, and a pair of scissors 30;

[0045] The driving assembly 20 is disposed on the connecting plate 10 , and the scissors 30 are disposed on the connecting plate 10 . The driving assembly 20 is used to drive the scissors 30 to open or close.

[0046] The above-mentioned wire cutter 100 is provided with scissors 30 on the connecting plate 10, and the scissors 30 are driven to open or close by the driving component 20, so that the scissors 30 can automatically cut the cable. Specifically, when cutting is required, the scissors 30 are driven to expand by the driving component 20, so that the cable can be placed between the blades of the scissors 30, and then the scissors 30 are driven to close by the driving component 20 to cut the cable. In this process, the operator does not need to touch the cable to cut the cable, which can greatly reduce the safety accidents caused by electric shock to the operator.

[0047] See also Figure 2 In some embodiments, the wire cutter 100 includes a scissors mounting rod, and the drive assembly 20 includes: a housing 21, a driving member 22, a first gear 23, a second gear 24, a transmission shaft 25, and a rotating member 40; the housing 21 is fixed at the upper end of the scissors mounting rod.

[0048] The connecting plate 10 is disposed in the housing 21, and the connecting plate 10 divides the housing 21 into a first cavity and a second cavity. The driving member 22, the first gear 23, and the second gear 24 are all disposed in the first cavity, and the rotating member 40 is rotatably disposed in the second cavity.

[0049] The first gear 23 is connected to the driving member 22, and the second gear 24 is rotatably arranged on the connecting plate 10. The first gear 23 is meshed with the second gear 24, and the second gear 24 is connected to the transmission shaft 25, and the transmission shaft 25 passes through the connecting plate 10 and is connected to the rotating member 40; when the transmission shaft 25 rotates, the rotating member 40 is driven to rotate; wherein, the axis of the first gear 23 is perpendicular to the axis of the second gear 24. In a specific application, the first gear 23 is located at the upper end of the scissors mounting rod, and the first gear 23 can be coaxially arranged with the scissors mounting rod, and the axis of the first gear 23 can be parallel to the connecting plate 10, and the driving member 22 can be a motor, which can be directly connected to the first gear 23 or connected to the first gear 23 through a reduction transmission mechanism (such as a reduction gear set). The first gear 23 and the second gear 24 can be bevel gears, and the diameter of the first gear 23 is smaller than the diameter of the second gear 24 to amplify the transmission torque. The axis of the second gear 24 is perpendicular to the connecting plate 10, the first gear 23 and the second gear 24 are vertically meshed, the driving member 22 (motor) can be built into the part near the upper end of the scissors mounting rod, and the scissors mounting rod can also be provided with a battery module and a control device (button or knob, etc.). The structure is compact. Of course, the driving assembly 20 can also use a motor and a worm gear to drive the scissors 30 to open and close.

[0050] It can be understood that the housing 21 is provided with a connecting plate 10, and the connecting plate 10 divides the housing 21 into a first cavity and a second cavity, wherein the first gear 23 and the second gear 24 are both arranged in the first cavity, and the axes of the first gear 23 and the second gear 24 are arranged vertically, and the driving member 22 is arranged below the first gear 23, that is, the housing 21 is as shown in FIG. Figure 2 As shown below, the driving member 22 is fixedly connected to the first gear 23. When the driving member 22 rotates, the first gear 23 can be driven to rotate. The second gear 24 is arranged on the connecting plate 10, and the second gear 24 is meshed with the first gear 23. In this way, when the driving member 22 rotates, the first gear 23 is driven to rotate, and then the second gear 24 is driven to rotate.

[0051] It can be understood that in order to enable the second gear 24 to drive the scissors 30 to open or close, a transmission shaft 25 is provided on the second gear 24, and the transmission shaft 25 extends through the connecting plate 10 to the second chamber. A rotating member 40 is provided on the side of the transmission shaft 25 away from the second gear 24, and the rotating member 40 can be driven by the second gear 24 to rotate, so that the scissors 30 can be driven to open or close. The above-mentioned rotating member 40 can rotate forward by a preset angle, and when the rotating member 40 rotates by the preset angle, the rotating member 40 can drive the scissors 30 to unfold, and the rotating member 40 can also rotate reversely by a preset angle, and when the rotating member 40 rotates reversely by a preset angle, the first shear 31 can be closed to cut the cable, so that the cable can be cut.

[0052] See also Figure 3 In some embodiments, the scissors 30 include: a first cutting piece 31 and a second cutting piece 32;

[0053] The second shearing piece 32 is fixedly arranged on the connecting plate 10, the first shearing piece 31 is movably arranged on the second shearing piece 32, the first shearing piece 31 is provided with a protrusion 33, the rotating member 40 is rotatably arranged on the housing 21 and is arranged on one side of the protrusion 33, and the rotating member 40 cooperates with the protrusion 33 to drive the second shearing piece 32;

[0054] The first cutting piece 31 has a first preset position and a second preset position, and the driving assembly 20 is used to drive the first cutting piece 31 to switch between the first preset position and the second preset position.

[0055] It can be understood that the scissors 30 include a first cutting piece 31 and a second cutting piece 32, the second cutting piece 32 is fixedly arranged on the connecting plate 10, and the first cutting piece 31 is movably arranged on the second cutting piece 32, and the first cutting piece 31 and the second cutting piece 32 are closely fitted, so that a good shearing force can be provided for the scissors 30. A protrusion 33 is provided at the part of the first cutting piece 31 close to the driving assembly 20, and the protrusion 33 is for the convenience of cooperating with the rotating member 40. Specifically, when the rotating member 40 rotates in the forward direction, the rotating member 40 can contact with the protrusion 33, and the protrusion 33 is pushed to move by the rotation of the rotating member 40, so that the first cutting piece 31 is rotated, so that the first cutting piece 31 and the second cutting piece 32 are separated, so that there is an opening between the first cutting piece 31 and the second cutting piece 32. After the cable is installed between the first cutting piece 31 and the second cutting piece 32, the rotating member 40 is rotated in the reverse direction, so that the rotating member 40 drives the first cutting piece 31 to rotate, and gradually closes, so that the first cutting piece 31 and the second cutting piece 32 cooperate to cut the cable.

[0056] It can be understood that when the first clip 31 is located at the first preset position, an opening is formed between the first clip 31 and the second clip 32, and the cable can be placed in the opening. When the first clip 31 is located at the second preset position, the first clip 31 and the second clip 32 are closed, and the cable can be cut by closing.

[0057] It can be understood that the working principle of the first shear 31 when it is located at the first preset position is: the driving member 22 rotates, driving the first gear 23 to rotate, the first gear 23 drives the second gear 24 to rotate, the second gear 24 drives the transmission shaft 25 to rotate, and the transmission shaft 25 drives the rotating member 40 to rotate. The first shear 31 can be driven to move relative to the second shear 32 (away from the second shear 32) through the rotating member 40, so that an opening is formed between the first shear 31 and the second shear 32.

[0058] The working principle when the first shearing piece 31 is located at the second preset position is as follows: the driving member 22 rotates in the opposite direction to drive the first gear 23 to rotate, the first gear 23 drives the second gear 24 to rotate, the second gear 24 drives the transmission shaft 25 to rotate, and the transmission shaft 25 drives the rotating member 40 to rotate. The first shearing piece 31 can be driven to move relative to the second shearing piece 32 (close to the shearing piece) through the rotating member 40, so that the first shearing piece 31 and the second shearing piece 32 are closed to achieve shearing.

[0059] See also Figure 3 or Figure 5 In some embodiments, the cutting edge of the second cutting blade 32 is configured to be an ellipse protruding away from the cutting back, and the cutting edge of the first cutting blade 31 is configured to be an arc-shaped recessed toward the cutting back. In specific applications, the cutting edge of the second cutting blade 32 may also be provided with an arc-shaped (e.g., semicircular) wire-cage groove, in which the cable may be partially clamped. When the first cutting blade 31 cuts the cable relative to the second cutting blade 32, the cable is limited by the wire-cage groove and is not easy to slip, which is conducive to ensuring one-time cutting.

[0060] It can be understood that the cutting edge of the second cutting blade 32 is set to be oval, and its specific shape is as follows: Figure 3 As shown, the cutting edge of the second cutting piece 32 is set to be an arc shape that is concave away from the first cutting piece 31. Setting the second cutting piece 32 to be an ellipse allows the first cutting piece 31 to achieve a larger shearing force with a smaller driving force when cooperating with the second cutting piece 32, and also can clamp the cable to prevent the cable from bursting out of the wire cutter.

[0061] It is understandable that the blade portion of the first shearing blade 31 is smaller than the blade handle portion, which can further provide a greater shearing force for the wire cutter 100. This is because the design of the wire cutter 100 is based on the lever principle, in which the blade length is equivalent to the resistance arm, and the handle length is equivalent to the force arm. By lengthening the handle length, a labor-saving effect can be achieved.

[0062] See also Figure 4 In some embodiments, the rotating member 40 includes: a first rotating portion 41, a connecting portion 42, and a second rotating portion 43;

[0063] The first rotating portion 41 and the second rotating portion 43 are arranged at intervals on both sides of the connecting portion 42 . The connecting portion 42 is connected to the transmission shaft 25 . The first rotating portion 41 and the second rotating portion 43 are both used to drive the second shearing blade 32 .

[0064] It can be understood that the rotating member 40 includes a first rotating part 41, a second rotating part 43 and a connecting part 42, wherein the first rotating part 41 and the second rotating part 43 are spaced apart on opposite sides of the connecting part 42; the connecting part 42 is used to connect with the transmission shaft 25, so that when the transmission shaft 25 rotates, it can drive the first rotating part 41 and the second rotating part 43 to rotate; specifically, when the first shearing piece 31 needs to be located at the first preset position, the first rotating part 41 cooperates with the protrusion 33 to drive the first shearing piece 31 to be located at the first position, and when the first shearing piece 31 needs to be located at the second preset position, the second rotating part 43 cooperates with the protrusion 33 to drive the first shearing piece 31 to be located at the second preset position.

[0065] Optionally, a support rod is provided under the shell 21, and a button is provided on the support rod, which can control the forward, reverse and stop of the motor 231. In this way, the wire cutter 100 can be supported by the support rod to keep the operator away from the cable. Then, the motor 231 can be controlled to rotate forward or reverse by controlling the button provided on the support rod, so that the scissors 30 can be opened or closed, thereby realizing remote control.

[0066] See also Figure 6 , the present invention also provides an electroscope 200, comprising: a body 210, a support member 220, a lifting mechanism 230, and a locking member 240;

[0067] The lifting mechanism 230 is disposed in the support member 220, and the lifting mechanism 230 is fixedly connected to the locking member 240. The lifting mechanism 230 is used to drive the locking member 240 to rise and fall; the main body 210 is disposed on the locking member 240, and the locking member 240 is used to cooperate with the support member 220 to clamp the cable.

[0068] The above-mentioned electroscope 200 includes a main body 210, a support member 220, a lifting mechanism 230, and a locking member 240, wherein the lifting mechanism 230 is arranged in the support member 220, and the locking member 240 is arranged at the lifting end of the lifting mechanism 230. When the lifting mechanism 230 is lifted or lowered, the lifting mechanism 230 can drive the locking member 240 to move. The locking member 240 is arranged on the main body 210. In this way, when the lifting mechanism 230 drives the locking member 240 to lift or lower, it can also drive the main body 210 to lift or lower.

[0069] It can be understood that the locking piece 240 can cooperate with the support piece 220 to fix the cable between the locking piece 240 and the support piece 220. Specifically, when the lifting mechanism 230 is lifted or lowered, a gap is generated between the locking piece 240 and the support piece 220. In this way, the cable can be installed on the support piece 220 through the gap. Then, the lifting mechanism 230 is lowered to press the locking piece 240 on the cable, so that the cable can be fixed. After the cable is fixed, the main body 210 is in the same position as the cable. In this way, the main body 210 can determine whether the cable is energized. At the same time, the tester 200 can also support the cable so that the cable will not fall after being cut, thereby improving the safety of the cable after being cut.

[0070] See also Figure 7 In some embodiments, the lifting mechanism 230 includes: a motor 231, a screw rod 232, and a slider 233;

[0071] The motor 231 is disposed on the support member 220, the lead screw 232 is connected to the motor 231, the slider 233 is disposed on the lead screw, and the slider 233 is connected to the locking member 240, and the lead screw is used to drive the slider 233 to move, thereby driving the locking member 240 to move.

[0072] It can be understood that the motor 231 is arranged in the support member 220, the middle part of the support member 220 is a hollow part, the screw rod 232 is arranged in the hollow part, and the slider 233 is also arranged in the hollow part; the motor 231 is connected to the screw rod 232, the slider 233 is arranged on the screw rod 232, and the slider 233 is connected to the locking member 240, so that when the motor 231 rotates, the motor 231 can drive the screw rod 232 to rotate, and the rotation of the screw rod 232 can drive the slider 233 to move, and then the slider 233 drives the locking member 240 to move, so that the locking member 240 is away from the support member 220 or the locking member 240 is close to the support member 220.

[0073] See also Figure 7 In some embodiments, the locking member 240 includes: an extending portion 241, a locking portion 242, and a limiting portion 243;

[0074] The extending portion 241, the locking portion 242, and the limiting portion 243 are connected in sequence, wherein the extending portion 241 is connected to the slider 233, the locking portion 242 is located above the limiting portion 243, and the locking portion 242 is used to cooperate with the limiting portion 243 to limit the movement of the cable.

[0075] It can be understood that the locking member 240 includes an extension portion 241, a locking portion 242, and a limiting portion 243, and the extension portion 241, the locking portion 242, and the limiting portion 243 are connected in sequence, wherein the extension portion 241 is used to be fixedly connected with the slider 233. In some embodiments, the slider 233 in the lifting mechanism 230 can be removed, and the extension portion 241 is set to a shape with threads and adapted to the screw rod 232, so that the extension portion 241 can be directly driven to move by the screw rod 232;

[0076] The locking portion 242 is the portion located at the top of the support member 220. The locking portion 242 can cooperate with the support member 220 to limit the displacement of the cable. A limiting portion 243 is provided on one side of the locking portion 242. The limiting portion 243 is used to limit the cable from leaking out of the locking portion 242, so that when the locking portion 242 fixes the cable, the cable can first contact the limiting portion 243. During the lifting and lowering process of the lifting mechanism 230, the cable can be located between the support member 220 and the locking portion 242 through the limiting portion 243.

[0077] In specific applications, the locking member 240 is thin-walled, and can be formed by stamping a metal plate, or can be an integrally formed plastic member. The lower end of the extension portion 241 is connected to the slider 233 located below the groove portion 224, and the extension portion 241 is close to one side of the groove portion 224, the upper end of the extension portion 241 is higher than the upper end of the groove portion 224, the first end of the locking portion 242 is integrally connected to the upper end of the extension portion 241, and a wire clamping groove is formed on the inner side of the locking portion 242, and its cross section is n-shaped or arc-shaped (semicircular), the opening of the wire clamping groove faces the upper side of the groove portion 224, and the opening width of the wire clamping groove is adapted to the width of the groove portion 224, so that the locking member can cover both sides of the groove portion 224. The limiting portion 243 is integrally connected to the second end of the locking portion 242, and the limiting portion 243 is arranged obliquely downwardly outwardly toward the opening of the wire clamping groove to form a flared structure. When the locking member 240 is downwardly engaged with the groove portion 224, the locking member 240 can cover the groove portion 224, and the two sides of the groove portion 224 can be abutted against the inner wall of the locking portion 242 to form a closed wire clamping groove to prevent the cable from loosening. In a specific application, the locking member 240 is first raised upward so that there is a sufficient distance between the limiting portion 243 and the groove portion 224 (such as Figure 7As shown in the figure, the cable enters from the gap under the locking portion 242, the locking member 240 descends, and the gap between the limiting portion 243 and the groove portion 224 is reduced.
