[0013] As a further optimization of the present invention, a second ring is rotatably mounted on the end of the first ring, and the end of the second ring is provided with an arc-shaped groove corresponding to the moving groove.

[0014] As a further optimization of the present invention, a movable block is slidably installed on the inner wall of the arc-shaped groove, and the inner wall of the movable groove is slidably connected to the outer surface of the movable block.

[0019] As a further optimization of the present invention, a clamping block is engaged at the end of the positioning rod, the outer surface of the clamping block is engaged with the inner wall of the docking block, and a pressing block is fixedly installed at the end of the positioning rod away from the clamping block, the outer surface of the pressing block is engaged with the end of the tray.

[0020] As a further optimization of the present invention, the stretching assembly includes a flip plate movably connected to the main body, a power component is fixedly installed at the end of the flip plate, and a transmission belt is attached to the output end of the power component;

The excess wire is wound up by the winding rod.

[0023] Compared with the prior art, the comprehensive tester for testing power distribution automation terminals provided by the present invention has the following beneficial effects: when the protective plate moves, the lines at the connection interface are straightened to ensure that the connection end of the connection line will not be bent too much, avoiding damage caused by the large bending of the connection line when plugging and unplugging the connection line, thereby reducing the situation of unstable or interrupted signal transmission.

[0024] The end of the flip plate has a rotating connecting block, which is slidably installed on one side of the main body. It can be freely adjusted according to the operating status, so that the connecting line will not bend too much, reducing the risk of physical damage to the cable due to excessive bending, which would affect signal transmission or current carrying capacity. When the gear ring rotates, it drives the connecting line that is attached to the outer surface of the power rod to rotate around the outer surface of the winding rod, so that the connecting line is wound on the winding rod. This avoids the internal conductor of the cable being affected by excessive stretching, which could lead to poor contact or damage. Together with the protective components, the connecting line is protected as a whole, reducing wear and stress concentration, and preventing the joint from being damaged by excessive external force.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Example: Please refer to Figures 1-11A comprehensive tester for testing power distribution automation terminals includes a main body 1. One end of the main body 1 is provided with a guide rail 11, and an adjustment component 2 is slidably installed on the inner wall of the guide rail 11. At the same time, a connection end 12 is fixedly installed on one end of the main body 1 and on both sides of the guide rail 11, and is connected to the power distribution terminal through the connection end 12.

[0042] In this design, the guide rail 11 is used to limit the adjustment component 2, and the position of the adjustment component 2 can be adjusted according to the actual situation to make it suitable for different scenarios. At the same time, a storage slot is provided on one side of the main body 1 for storing the protective component 3, thereby reducing the risk of the protective component 3 being bumped or knocked during transportation.

[0043] Furthermore, the protective component 3 is assembled at the end of the adjusting component 2, and works with the adjusting component 2 to adjust the position of the protective component 3, while also limiting the connection line through the protective component 3; wherein, the protective component 3 includes a docking block 31, a telescopic rod 32 is fixedly installed at the end of the docking block 31, a fixing plate 33 is fixedly installed at the end of the telescopic rod 32, and an adjusting rod 331 is fixedly installed at the end of the fixing plate 33, and a protective plate 34 is fixedly installed at the end of the adjusting rod 331 away from the fixing plate 33.

[0044] In this embodiment, the outer surface of the docking block 31 is provided with a docking groove, and the inner wall of the docking groove is engaged with the outer surface of the clamping block 26, so that the protective component 3 is stably fixed at the end of the adjusting component 2 and moves with the adjusting component 2.

[0045] The telescopic rod 32 consists of a sleeve and a rod. The outer surface of the sleeve has multiple sets of through holes. After the sleeve and rod move to the appropriate position, the rod is locked by a screw set inside the through hole, thereby moving the fixing plate 33 to the designated position.

[0046] Meanwhile, the adjusting rod 331 is composed of a cylinder, a rod and a spring, and the inner wall of the cylinder is slidably connected to the outer surface of the rod. The spring is set between the cylinder and the rod to support the rod and ensure that the protective plate 34 set at the end of the rod is kept in a certain position.

[0047] A baffle is rotatably mounted on one side of the protective plate 34. When the baffle is open, the inner wall of the protective plate 34 is connected to the outside. When the baffle is closed, the protective plate 34 is isolated from the outside. A torsion spring is provided at the connection between the baffle and the protective plate 34 to support the baffle.

[0048] Furthermore, multiple sets of first support rods 332 are rotatably mounted on the end of the fixing plate 33, and the multiple sets of first support rods 332 are evenly distributed on the end of the fixing plate 33. At the same time, limit blocks 35 are rotatably mounted on the end of the first support rods 332.

[0049] The end of the protective plate 34 is rotatably mounted with a second support rod 341 corresponding to the first support rod 332. The end of the second support rod 341 away from the protective plate 34 is rotatably connected to the end of the limiting block 35. The inner wall of the limiting block 35 is slidably mounted with a positioning plate 351. The end of the positioning plate 351 is fixedly mounted with a locking block 352. The connection line is limited by the fixing plate 33, the protective plate 34 and the locking block 352.

[0050] Specifically, the end of the limiting block 35 is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected to the outer surface of the positioning plate 351, so that the protective plate 34 moves along the moving trajectory of the adjusting rod 331, and the limiting block 35 moves on the positioning plate 351 in conjunction with the second support rod 341 and the first support rod 332.

[0051] Simultaneously, as the protective plate 34 moves, the wiring at the connection interface is straightened, and after repeated movement of the protective plate 34, bending of the connection wiring is prevented. This avoids damage caused during plugging and unplugging.

[0052] Furthermore, a first ring 36 is fixedly installed on the end of the positioning plate 351 away from the locking block 352. Multiple sets of moving grooves 361 are opened at the end of the first ring 36, and the multiple sets of moving grooves 361 are evenly distributed at the end of the first ring 36.

[0053] A second ring 37 is rotatably mounted on the end of the first ring 36, and an arc-shaped groove 371 corresponding to the moving groove 361 is formed at the end of the second ring 37. A moving block 38 is slidably mounted on the inner wall of the arc-shaped groove 371, and the inner wall of the moving groove 361 is slidably connected to the outer surface of the moving block 38.

[0054] Specifically, when the second ring 37 rotates, it moves the moving block 38 in conjunction with the arc groove 371. Since the outer surface of the moving block 38 is slidably connected to the inner wall of the moving groove 361, the moving block 38 moves along the inner wall of the moving groove 361 after being subjected to force, causing the moving block 38 to move outward or move towards the center.

[0055] Since the end of the first ring 36 is fixedly installed on the positioning plate 351, and the positioning plate 351 is limited by the first support rod 332 and the second support rod 341 in conjunction with the limiting block 35, the positioning plate 351 is guaranteed to maintain its position and simultaneously limit the first ring 36.

[0056] Furthermore, a pressing rod 381 is rotatably mounted on the outer surface of the movable block 38. The outer surface of the pressing rod 381 is slidably connected to the inner wall of the positioning plate 351. At the same time, the end of the pressing rod 381 penetrates and extends to the inner wall of the locking block 352, thereby limiting the connection line.

[0057] Specifically, when the moving block 38 moves, it synchronously drives the pressing rod 381, which is rotatably mounted on its outer surface, to move. Since the outer surface of the pressing rod 381 is slidably connected to the inner wall of the positioning plate 351, the pressing rod 381 moves along the inner wall of the positioning plate 351, thereby fixing the connecting line inside the locking block 352. The end of the pressing rod 381 is provided with rubber or other anti-slip components.

[0058] Furthermore, a movable groove 372 is provided at the end of the second ring 37 and on one side of the arc groove 371. A movable block 373 is slidably installed on the inner wall of the movable groove 372, and the end of the movable block 373 is fixedly connected to the end of the fixed plate 33.

[0059] Specifically, the second ring 37 is defined by the movable block 373 fixedly connected to the fixed plate 33. The end of the movable block 373 engages with the inner wall of the movable groove 372, while the outer surface of the movable block 373 can slide on the inner wall of the movable groove 372. Since the end of the first ring 36 and the end of the second ring 37 are fitted and slidably connected, the stability of the second ring 37 and the first ring 36 is ensured.

[0060] Furthermore, the adjustment component 2 includes a guide block 22 that is slidably connected to the guide rail 11. A base plate 21 is fixedly installed at the end of the guide block 22, and a telescopic member 27 is fixedly installed at the upper end of the base plate 21. Meanwhile, a support plate 28 is fixedly installed at the output end of the telescopic member 27.

[0061] In this embodiment, the outer surfaces of the guide block 22 and the guide rail 11 are provided with anti-slip components such as rubber, so that after the guide block 22 moves, it can be stably locked in the moved position.

[0062] The telescopic component 27 is a component with telescopic function, such as an electric telescopic rod, and is connected to an external control device. When the telescopic component 27 is started, it synchronously drives the tray 28 set at its output end to move until the tray 28 moves to the appropriate position and then stops.

[0063] Furthermore, support columns 23 are fixedly installed at the ends of the base plate 21 and on both sides of the support plate 28. Meanwhile, an adjusting block 24 is slidably installed on one side of the support column 23, and a positioning rod 25 is rotatably installed at the end of the adjusting block 24.

[0064] Specifically, an adjustment groove is provided on one side of the support column 23, and the inner wall of the adjustment groove is slidably connected to the outer surface of the adjustment block 24. At the same time, after the adjustment block 24 moves to the appropriate position, the adjustment block 24 is tightly fixed to the inner wall of the adjustment groove by a screw or other locking component.

[0065] The rotation point of the positioning rod 25 is adjusted by adjusting the position of the adjusting block 24, so that the positioning rod 25 is always in the optimal position.

[0066] Furthermore, a clamping block 26 is engaged at the end of the positioning rod 25, and the outer surface of the clamping block 26 engages with the inner wall of the mating block 31. A pressing block 29 is fixedly installed at the end of the positioning rod 25 away from the clamping block 26, and the outer surface of the pressing block 29 engages with the end of the support plate 28.

[0067] Specifically, when the pallet 28 moves, it drives the pressing block 29 to move. Since the pressing block 29 is fixedly installed on the positioning rod 25, the positioning rod 25 rotates around the connection with the adjusting block 24, causing the clamping block 26 at the end away from the pressing block 29 to move towards the middle and engage with the inner wall of the docking block 31, ensuring the stability of the docking block 31.

[0068] A torsion spring is provided at the connection between the positioning rod 25 and the adjusting block 24, so that the pressing block 29 on the positioning rod 25 is always in contact with the end of the tray 28.

[0069] Furthermore, the stretching assembly 4 includes a flip plate 41 that is movably connected to the main body 1. A power component 42 is fixedly installed at the end of the flip plate 41, and a transmission belt 43 is attached to the output end of the power component 42.

[0070] In this embodiment, the end of the flip plate 41 has a connecting block that rotates and is slidably installed on one side of the main body 1. It can be freely adjusted according to the operating state, so that the connection line will not be bent too much, reducing the risk of physical damage to the cable due to excessive bending, thereby affecting the signal transmission or current carrying capacity.

[0071] The power component 42 is a device with power output, such as a motor, and is connected to an external control device. When the power component 42 is started, it synchronously drives the transmission belt 43 located at its output end to rotate.

[0072] Furthermore, a power plate 44 is fixedly installed on one side of the flip plate 41. Multiple sets of power gears 45 are rotatably installed on the inner wall of the power plate 44, and the multiple sets of power gears 45 are evenly distributed on the inner wall of the power plate 44. At the same time, the outer surface of the end of the power gear 45 is in contact with the inner wall of the transmission belt 43.

[0073] Specifically, the drive belt 43 drives the power gear 45, which is fitted inside it, to rotate. When the power gear 45 rotates, it synchronously drives the gear ring 46, which meshes with the outer surface of the power gear 45, to rotate.

[0074] Furthermore, a gear ring 46 is rotatably mounted on the inner wall of the power plate 44, and the outer surface of the gear ring 46 meshes with the outer surfaces of multiple sets of power gears 45. A power rod 47 is fixedly mounted on the end of the gear ring 46, and a winding rod 48 is fixedly mounted on the end of the flip plate 41 and located in the inner cavity of the power plate 44. The excess wire is wound up by the winding rod 48.

[0075] Specifically, when the gear ring 46 rotates, it drives the connecting wires that are attached to the outer surface of the power rod 47 to rotate around the outer surface of the winding rod 48, thereby causing the connecting wires to be wound around the winding rod 48, so as to avoid the internal conductor of the cable being affected by excessive stretching, which could lead to poor contact or damage.

[0076] The control device can be a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0077] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
