In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Example: See Figures 1-11A comprehensive tester for testing distribution automation terminals includes a main body 1, a guide rail 11 is opened at one end of the main body 1, and an adjustment component 2 is slidably installed on the inner wall of the guide rail 11, and a connecting 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 distribution end through the connecting end 12.

[0042] In this solution, the guide rail 11 defines the adjustment assembly 2, and the position of the adjustment assembly 2 can be adjusted according to the actual situation, making it suitable for different scenarios. At the same time, a storage slot is opened on one side of the main body 1 for storing the protective assembly 3, thereby reducing the protective assembly 3 from being significantly bumped during transportation.

[0043] Furthermore, the protective component 3 is assembled at the end of the adjusting component 2, and cooperates with the adjusting component 2 to adjust the position of the protective component 3, and at the same time limits the connection line through the protective component 3; wherein, the protective component 3 includes a docking block 31, and a telescopic rod 32 is fixedly installed at the end of the docking block 31, and a fixed 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 fixed plate 33, and a protective plate 34 is fixedly installed at the end of the adjusting rod 331 away from the fixed plate 33.

[0044] In this embodiment, a docking groove is provided on the outer surface of the docking block 31, 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 on the end of the adjustment component 2 and moves with the adjustment component 2.

[0045] The telescopic rod 32 is composed of a sleeve and a sleeve rod. At the same time, a plurality of through holes are opened on the outer surface of the sleeve. After the sleeve and the sleeve rod are moved to the appropriate position, the sleeve rod is locked by a screw arranged inside the through hole, thereby moving the fixing plate 33 to the specified position.

[0046] At the same time, the adjusting rod 331 is composed of a cylinder, a round rod and a spring, and the inner wall of the cylinder is slidingly connected to the outer surface of the round rod. At the same time, the spring is arranged between the cylinder and the round rod to support the round rod and ensure that the protective plate 34 arranged at the end of the round rod remains in a certain position.

[0047] A baffle is rotatably installed 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, a plurality of first support rods 332 are rotatably mounted on the end of the fixing plate 33 , and the plurality of first support rods 332 are evenly distributed on the end of the fixing plate 33 . Meanwhile, a limit block 35 is rotatably mounted on the end of the first support rod 332 .

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

[0050] Specifically, a limiting groove is opened at the end of the limiting block 35, 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 cooperates with the second support rod 341 and the first support rod 332 to make the limiting block 35 move on the positioning plate 351.

[0051] At the same time, when the protective plate 34 moves, the line at the connection line interface is straightened, and after the protective plate 34 moves repeatedly, the connection line is prevented from being bent, thereby avoiding damage caused by plugging and unplugging.

[0052] Furthermore, a first ring 36 is fixedly mounted on one end of the positioning plate 351 away from the locking block 352 . A plurality of movable grooves 361 are formed at the end of the first ring 36 , and the plurality of movable grooves 361 are evenly distributed at the end of the first ring 36 .

[0053] The end of the first ring 36 is rotatably mounted with a second ring 37, and the end of the second ring 37 is provided with an arcuate groove 371 corresponding to the movable groove 361. The inner wall of the arcuate groove 371 is slidably mounted with a movable block 38, and the inner wall of the movable groove 361 is slidably connected to the outer surface of the movable block 38.

[0054] Specifically, when the second ring 37 rotates, it cooperates with the arc groove 371 to drive the moving block 38 to move. Since the outer surface of the moving block 38 is slidingly connected to the inner wall of the moving groove 361, after the moving block 38 is subjected to force, it moves along the inner wall of the moving groove 361, causing the moving block 38 to move outward or closer to the middle.

[0055] Since the end of the first ring 36 is fixedly mounted 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 cooperation with the limit block 35 , the positioning plate 351 is ensured to maintain its position and the first ring 36 is limited synchronously.

[0056] Furthermore, an extrusion rod 381 is rotatably installed on the outer surface of the moving block 38, and the outer surface of the extrusion rod 381 is slidingly connected to the inner wall of the positioning plate 351. At the same time, the end of the extrusion rod 381 passes through and extends to the inner wall of the locking block 352, and the connection line is limited by the extrusion rod 381.

[0057] Specifically, when the moving block 38 moves, it synchronously drives the extrusion rod 381 installed on its outer surface to move. Since the outer surface of the extrusion rod 381 is slidingly connected to the inner wall of the positioning plate 351, the extrusion rod 381 moves along the inner wall of the positioning plate 351, thereby fixing the connection line inside the locking block 352. The end of the extrusion rod 381 is provided with a component such as rubber that has an anti-slip function.

[0058] Furthermore, a movable groove 372 is formed at the end of the second ring 37 and on one side of the arc groove 371 . A movable block 373 is slidably mounted on the inner wall of the movable groove 372 . 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 limited by a movable block 373 fixedly connected to the fixed plate 33, wherein the end of the movable block 373 is engaged with the inner wall of the movable groove 372, and 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 engaged and slidably connected, the stability of the second ring 37 and the first ring 36 is ensured.

[0060] Furthermore, the adjustment assembly 2 includes a guide block 22 slidably connected to the guide rail 11, the end of the guide block 22 is fixedly mounted with a base plate 21, and the upper end of the base plate 21 is fixedly mounted with a telescopic member 27, while the output end of the telescopic member 27 is fixedly mounted with a support plate 28.

[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 engaged in the moved position.

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

[0063] Furthermore, support columns 23 are fixedly installed at the ends of the bottom plate 21 and on both sides of the supporting plate 28. At the same time, an adjustment 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 adjustment block 24.

[0064] Specifically, an adjustment groove is opened 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 a suitable position, the adjustment block 24 is tightly confined to the inner wall of the adjustment groove by a component with a locking function such as a screw.

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

[0066] Furthermore, the end of the positioning rod 25 is clamped with a clamping block 26, and the outer surface of the clamping block 26 is clamped with the inner wall of the docking block 31. The end of the positioning rod 25 away from the clamping block 26 is fixedly mounted with a pressing block 29, and the outer surface of the pressing block 29 is connected to the end of the support plate 28.

[0067] Specifically, when the support plate 28 moves, the pressing block 29 is driven to move. Since the pressing block 29 is fixedly mounted on the positioning rod 25, the positioning rod 25 rotates around the connection with the adjustment block 24, so that the clamping block 26 at one end away from the pressing block 29 moves closer to the middle, and the clamping block 26 is clamped on the inner wall of the docking block 31 to ensure the stability of the docking block 31.

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

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

[0070] In this embodiment, a connecting block is rotatably provided at the end of the flip plate 41, which is slidably installed on one side of the main body 1 and can be freely adjusted according to the operating status so that the connecting line will not produce large bends, thereby reducing the risk of physical damage to the cable due to excessive bending, thereby affecting signal transmission or current flow capacity.

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

[0072] Furthermore, a power plate 44 is fixedly installed on one side of the flip plate 41, and 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 transmission belt 43 drives the power gear 45 fitted inside the transmission belt 43 to rotate, and when the power gear 45 rotates, the gear ring 46 meshing with the outer surface of the power gear 45 is synchronously driven to rotate.

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

[0075] Specifically, when the gear ring 46 rotates, it drives the connecting line attached to the outer surface of the power rod 47 to rotate around the outer surface of the winding rod 48, so that the connecting line is wound around the winding rod 48, avoiding excessive stretching that may affect the internal conductor of the cable and cause poor contact or damage.

[0076] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0077] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
