The front of the conductivity meter body has a display screen, and a test pen is located on one side. A wire is electrically connected to the top of the test pen, and a positioning ring is fixedly inserted through the middle of the test pen. The housing is located on the back of the conductivity meter body, and a sealing plate is located on the back of the housing. Three positioning seats are fixedly connected to the side of the housing, one of which has two positioning mechanisms inside. Multiple isolation plates are fixedly connected inside the housing, forming multiple wire grooves. This invention utilizes the design of the housing and multiple isolation plates to form multiple placement grooves, allowing the wire to be placed inside the housing, thus preventing creases and breakage of the wire during transport.
[0004] This device uses a cable tray to hold the cable inside, effectively preventing creases or breakage during transport. However, when storing the cable, it must be placed slowly and orderly into the cable tray to ensure a smooth storage process, which limits the storage speed and makes the device somewhat inconvenient to operate when storing cables. Utility Model Content
[0005] To address the aforementioned issues, a portable conductivity meter is provided. By utilizing cross-arranged compression blocks and rollers, the wires are stored in an "S" shape inside the storage box. This not only prevents the wires from creased or broken during transport but also allows for quick and easy storage of the wires.
[0006] To address the problems of existing technologies, this utility model provides a portable conductivity meter, including a conductivity meter body; a storage box is provided at the rear end of the conductivity meter body; a wire is connected to the side wall of the storage box, and one end of the wire is connected to a test pen; an upper moving block and a lower moving block are movably arranged inside the storage box; a plurality of squeezing blocks are arranged crosswise on opposite sides of the upper and lower moving blocks; a roller for squeezing the wire is provided at one end of the squeezing block; a symmetrical upper rack is provided on the side wall of the upper moving block; a symmetrical lower rack is provided on the side wall of the lower moving block; and a gear that meshes with the upper and lower racks is rotatably arranged on the inner wall of the storage box.
[0007] Preferably, the inner wall of the storage box is further provided with symmetrical sliding rods; symmetrical sliders are slidably provided on the outside of the sliding rods; the two sliders are respectively connected to the upper moving block and the lower moving block; a first spring is sleeved on the outside of the sliding rods; the two ends of the first spring are respectively connected to the side walls of the two sliders.
[0008] Preferably, the side wall of the upper movable block is provided with a connecting block; the side wall of the storage box is provided with a moving groove for the connecting block to move; the interior of the connecting block is provided with a through hole for the wire to move; and one side of the connecting block is provided with a placement plate for placing a test pen.
[0009] Preferably, the outer wall of the placement plate is provided with an arc-shaped magnet; the outside of the test pen is provided with an iron ring that is magnetically connected to the arc-shaped magnet.
[0010] Preferably, the outer wall of the placement plate is further provided with a mounting ring; the outer wall of the test pen is provided with a compression ring that works in conjunction with the mounting ring, and the diameter of the compression ring is larger than the diameter of the mounting ring.

[0012] The advantages of this utility model compared to the prior art are:
[0013] By placing the test pen inside the mounting ring until the compression ring contacts the mounting ring, and then pressing down on the test pen and compression ring until the locking block is engaged in the slot, the mounting ring and placement plate will move downwards under the pressure of the compression ring, thus driving the connecting block and the upper moving block downwards. At the same time, the upper rack will move downwards, further driving the gear to rotate. The rotation of the gear will also drive the lower moving block to move upwards. That is, when the upper and lower moving blocks approach each other, the compression block and roller on the opposite side of the upper and lower moving blocks approach each other. Since the compression block and roller are arranged in a cross shape, the wire will be stored in the storage box in an "S" shape under the cross-shaped compression block and roller. This avoids the wire from getting creased or broken during transport and allows for quick storage of the wire. Attached Figure Description

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0024] like Figures 1 to 8 As shown, this utility model provides:
[0025] A portable conductivity meter includes a conductivity meter body 1; a storage box 2 is provided at the rear end of the conductivity meter body 1; a wire 16 is connected to the side wall of the storage box 2, and one end of the wire 16 is connected to a test pen 3; an upper moving block 5 and a lower moving block 6 are movably arranged inside the storage box 2; a plurality of pressing blocks 8 are arranged crosswise on the opposite side of the upper moving block 5 and the lower moving block 6; a roller 9 for pressing the wire 16 is provided at one end of the pressing block 8; a symmetrical upper rack 13 is provided on the side wall of the upper moving block 5; a symmetrical lower rack 15 is provided on the side wall of the lower moving block 6; a gear 14 is rotatably arranged on the inner wall of the storage box 2, meshing with the upper rack 13 and the lower rack 15.
[0026] The upper moving block 5 moves downward, causing the upper rack 13 to move downward, which in turn drives the gear 14 to rotate. At the same time, the rotation of the gear 14 also causes the lower moving block 6 to move upward. When the upper moving block 5 and the lower moving block 6 approach each other, the pressing block 8 and the roller 9 on the opposite side of the upper moving block 5 and the lower moving block 6 approach each other. Since the pressing block 8 and the roller 9 are arranged in a cross shape, the wire 16 will be stored in the storage box 2 in an "S" shape under the cross-arranged pressing block 8 and roller 9. This avoids the wire 16 from getting creased or broken during carrying and allows for quick storage of the wire 16.
[0027] like Figure 5 and Figure 6 As shown, the inner wall of the storage box 2 is also provided with symmetrical sliding rods 10; symmetrical sliders 11 are slidably provided on the outside of the sliding rods 10; the two sliders 11 are respectively connected to the upper moving block 5 and the lower moving block 6; a first spring 12 is sleeved on the outside of the sliding rods 10; the two ends of the first spring 12 are respectively connected to the side walls of the two sliders 11.
[0028] The elastic force of the first spring 12 can drive the upper moving block 5 and the lower moving block 6 to move, so that the squeezing block 8 and the roller 9 on the opposite side of the upper moving block 5 and the lower moving block 6 move away from each other, thereby breaking away from contact with the wire 16.
[0029] like Figure 2 and Figure 7As shown, the upper movable block 5 has a connecting block 7 on its side wall; the storage box 2 has a moving groove on its side wall for the connecting block 7 to move; the connecting block 7 has a through hole for the wire 16 to move inside; and a placement plate 4 for placing the test pen 3 is provided on one side of the connecting block 7.
[0030] The placement plate 4 effectively limits the movement of the test pen 3, preventing it from falling out when not in use and thus avoiding potential damage or loss.
[0031] like Figure 8 As shown, the outer wall of the placement plate 4 is provided with an arc-shaped magnet 17; the outside of the test pen 3 is provided with an iron ring 18 that is magnetically connected to the arc-shaped magnet 17.
[0032] The coordinated action between the arc-shaped magnet 17 and the iron ring 18 effectively enhances the stability of the test pen 3 during placement, allowing it to remain more firmly in the predetermined position.
[0033] like Figure 8 As shown, the outer wall of the placement plate 4 is also provided with a mounting ring 19; the outer wall of the test pen 3 is provided with a compression ring 20 that works in conjunction with the mounting ring 19, and the diameter of the compression ring 20 is larger than the diameter of the mounting ring 19.
[0034] The compression ring 20 drives the mounting ring 19 to move downward. Since the diameter of the compression ring 20 is larger than the diameter of the mounting ring 19, the mounting ring 19 and the placement plate 4 will move downward under the compression of the compression ring 20.
[0035] like Figure 8 As shown, a pull rod 23 is movably installed inside the placement plate 4; a locking block 21 is provided at one end of the pull rod 23, and a slot adapted to the locking block 21 is provided on the side wall of the storage box 2; a second spring 22 is sleeved on the outside of the pull rod 23; the two ends of the second spring 22 are respectively connected to the side wall of the storage box 2 and the side wall of the placement plate 4.
[0036] The test pen 3 and the placement plate 4 are secured in the slot by the locking block 21, ensuring that they remain stable when not in use. The tight fit between the locking block 21 and the slot ensures that the test pen 3 and the placement plate 4 will not move or fall off when idle, thus preventing possible damage or loss.
[0037] Working principle: When the test pen 3 is needed, first pull the lever 23, so that the locking block 21 at one end of the lever 23 moves away from the slot on the side wall of the storage box 2. At this time, under the elastic force of the first spring 12, the slider 11, the upper moving block 5, the connecting block 7, and the placement plate 4 will all move upward. When the upper moving block 5 moves upward, it will drive the upper rack 13 to move. At the same time, the upper rack 13 will also drive the gear 14 to rotate. The rotating gear 14 can drive the lower rack 15 to move downward, and at the same time, it will drive the lower moving block 6 to move downward. When the upper moving block 5 and the lower moving block 6 move away from each other, the squeezing block 8 and the roller 9 on the opposite side of the upper moving block 5 and the lower moving block 6 will also move away from each other, thus relieving the squeezing of the wire 16. At this time, the test pen 3 can be taken out and the wire 16 can be dragged and moved freely. When it is necessary to store the wire 16 and the test pen 3, the test pen 3 is placed inside the mounting ring 19 until the squeezing ring 20 and the wire 16 are squeezed together. When the mounting ring 19 comes into contact with the device, the test pen 3 and the compression ring 20 are pressed downwards until the locking block 21 is inserted into the slot. Since the diameter of the compression ring 20 is larger than that of the mounting ring 19, the mounting ring 19 and the placement plate 4 will move downwards under the compression of the compression ring 20, thereby driving the connecting block 7 and the upper moving block 5 to move downwards. At the same time, the upper rack 13 will move downwards, further driving the gear 14 to rotate. The rotation of the gear 14 will also drive the lower moving block 6 to move upwards. That is, when the upper moving block 5 and the lower moving block 6 approach each other, the compression block 8 and the roller 9 on the opposite side of the upper moving block 5 and the lower moving block 6 approach each other. Since the compression block 8 and the roller 9 are arranged in a cross shape, the wire 16 will be stored in the storage box 2 in an "S" shape under the cross-arranged compression block 8 and roller 9. This avoids the wire 16 from getting creased or broken during carrying and allows for quick storage of the wire 16.
[0038] The above embodiments merely illustrate one or several implementations of the portable conductivity meter of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
