[0002] The network cable is a conductor used to transmit data information in the network line. Network cable fixing means that during the cable wiring process, the network cable needs to be firmly fixed to the wall, floor or other supports to ensure the stability and security of the network connection. Common network cable fixing methods include using nails, screws, fixing clamps, tape, etc. After the network cable is fixed, it will avoid the problem of unstable signal caused by loose connection between the network cable and the gateway.

[0056] The waist-shaped hole 204 is provided to facilitate the adjustment of the crossbar 302 and the support plate 301, thereby ensuring the normal operation of the device.

[0057] As an optimization solution of this embodiment, in order to ensure that the limit rod 4 is always in contact with the crystal head, the crystal head is fixed, such as Figure 7As shown, the pulling member 6 includes a spring 604, a guide rod 601, a fixed block 603, a sliding block 605 and a push-pull rod 602, the two ends of the fixed block 603 are respectively fixedly mounted on the support rod 205 on both sides of the center line of the vertical plate 201, the two ends of the guide rod 601 are respectively fixedly mounted on the vertical plate 201 and the fixed block 603, the sliding block 605 is slidably mounted on the guide rod 601, the spring 604 is sleeved on the guide rod 601, and the spring 604 is located between the sliding block 605 and the fixed block 603, and the two ends of the push-pull rod 602 are respectively rotatably mounted on the sliding block 605 and the support plate 301.

[0058] The guide rod 601 is used to guide the sliding block 605 to ensure the normal operation of the sliding block 605. The spring 604 is convenient for driving the sliding block 605 to reset. The push-pull rod 602 is used to pull the support plate 301 to ensure that the support plate 301 can drive the limit rod 4 to limit the crystal head, thereby ensuring the safety of the crystal head during operation.

[0059] As an optimization solution of this embodiment, Figure 5 As shown, a mounting groove 305 is formed on the support plate 301 , an adjusting mechanism 5 is arranged in the mounting groove 305 , and the limiting rod 4 is mounted on the adjusting mechanism 5 .

[0060] The setting of the adjustment mechanism 5 ensures that the device can fix crystal plugs of different sizes, which greatly ensures the working flexibility of the device.

[0061] As an optimization solution of this embodiment, in order to ensure that the device can fix crystal plugs of different sizes at the same time, the following is set Figure 6 As shown, the adjustment mechanism 5 includes a rotating shaft 502, a gear 501, a first rack 504, and a second rack 506. The gear 501 is rotatably installed in the middle of the mounting groove 305 via the rotating shaft 502. The first rack 504 and the second rack 506 are symmetrically arranged on both sides of the gear 501, and the first rack 504 and the second rack 506 are both meshed with the gear 501. The limiting rods 4 arranged on both sides of the center line of the support plate 301 are respectively connected to the first rack 504 and the second rack 506.

[0062] The gear 501 is driven to rotate by rotating the rotating shaft 502, and the gear 501 is meshed with the first rack 504 and the second rack 506. The rotation of the gear 501 drives the first rack 504 and the second rack 506 to move outward or inward, thereby driving the limit rods 4 arranged on both sides of the center line of the support plate 301 to move outward or inward, thereby greatly improving the flexibility of the device.

[0063] As an optimization solution of this embodiment, in order to ensure the stability of the first rack 504 and the second rack 506 during the movement, the following is set: Figure 5 As shown, a guide rail 306 is fixedly mounted on the inner wall of the mounting groove 305. Figure 6 As shown, guide grooves 503 are formed on the side walls of the first rack 504 and the second rack 506 , and the guide rails 306 are slidably matched with the guide grooves 503 .

[0064] The setting of the guide rail 306 and the slide groove can guide the first rack 504 and the second rack 506 on the one hand, and prevent the first rack 504 and the second rack 506 from shaking during the movement to the sides, thereby ensuring the normal operation of the limit rod 4.

[0065] As an optimization solution of this embodiment, in order to facilitate the rotation of the rotating shaft 502 and the gear 501, as Figure 6 As shown, a hexagonal adjustment slot 505 for easy adjustment is provided on the top of the rotating shaft 502 . The staff drives the rotating shaft 502 to rotate by using a wrench or an electric wrench, and the rotation of the rotating shaft 502 drives the gear 501 to rotate.

[0066] The provision of the hexagonal adjusting slot 505 facilitates the adjustment of the device, ensuring that the device can fix crystal heads of different sizes, thereby greatly improving the flexibility of the device during use.

[0067] like Figure 8 As shown, during operation, pulling the support plate 301 drives the limit rod 4 to move forward, so that the limit rod 4 can contact the end of the crystal head. The movement of the support plate 301 will drive the rotating shaft 304 to move in the waist-shaped hole 204. While pulling the support plate 301, the push-pull rod 602 will drive the sliding block 605 to move on the guide rod 601. The movement of the sliding block 605 will compress the spring 604, and the rotating limit rod 4 and the support plate 301 will rotate along the rotating shaft 304, so that the limit rod 4 contacts the end of the crystal head. Under the action of the spring 604, the support plate 301 will always be pulled backward. Since the rotating shaft 304 and the waist-shaped hole 204 are slidably matched, the support plate 301 will not be driven to rotate along the rotating shaft 304, but the support plate 301 will be driven to move backward as a whole. When the limit rod 4 contacts the crystal head, the purpose of fixing the crystal head will be achieved.

[0068] When adjusting the distance between the limit rods 4 set on both sides of the support plate 301, the rotating shaft 502 can be driven to rotate by a wrench or an electric wrench, and the rotation of the rotating shaft 502 drives the gear 501 to rotate, and the rotation of the gear 501 drives the first rack 504 and the second rack 506 to move outward or inward at the same time, ensuring that the device can fix crystal heads of different sizes, improving the flexibility of the device during operation, and improving the use scenarios of the device.
