The limiting cap is fixedly connected to the end of the tension spring 5 away from the hole 101.

[0033] In addition, the "hinging" mentioned in the above technical solution belongs to the prior art. Here we briefly give an example and introduce a hinging method: Figure 2 and Figure 4 As shown, the first end plate 1 and the second end plate 3 are both provided with ears, and the ears are used to connect with the first connecting plate 2 and the second connecting plate 4. The first end plate 1 and the first connecting plate 2, the first connecting plate 2 and the second end plate 3, and the second end plate 3 and the second connecting plate 4 are all hingedly connected through a hinge shaft 8 mounted on the ears. One end of the hinge shaft 8 is provided with a thread, and the other end of the hinge shaft 8 is provided with a groove. The groove is used to engage with a tool to screw the hinge shaft 8. The end of the hinge shaft 8 with a thread is threadedly connected to the corresponding ear.

[0034] Principle: The first end plate 1, the first connecting plate 2, the second end plate 3, the second connecting plate 4, the tension spring 5 and the latch 6 form an inseparable whole, which is not easy to be lost or fall into some narrow gaps in space.

[0035] To open the cable clamp: pull the latch 6 outward through the limit cap and make the latch 6 escape from the socket 401, then the second connection plate 4 can be opened; to close the cable clamp: pull the latch 6 outward and make the latch 6 enter the first end plate 1, put the second connection plate 4 on the first end plate 1, align the socket 401 with the latch 6, release the latch 6, and the latch 6 is inserted into the socket 401 under the tension of the tension spring 5. In summary, the opening and closing process of the utility model is simple and easy to operate, so it is easy to install and replace.

[0036] Example 2

[0037] The difference between Example 2 and Example 1 is that the plug-in components are different.

[0038] like Figure 1 and 5 As shown in ~10, it includes a first end plate 1, one end of the first end plate 1 is hinged with a first connecting plate 2, the end of the first connecting plate 2 away from the first end plate 1 is hinged with a second end plate 3, the end of the second end plate 3 away from the first connecting plate 2 is hinged with a second connecting plate 4, and the end of the first end plate 1 away from the first connecting plate 2 is installed with a plug-in assembly, which is plugged with the end of the second connecting plate 4 away from the second end plate 3.

[0039] The plug assembly includes a tension spring 7 and a latch 6. A hole 101 is provided on the ear of the first end plate 1 and the hinged end of the second connecting plate 4. The tension spring 7 is coaxially arranged with the hole 101. One end of the tension spring 7 abuts against the bottom wall of the hole 101. One end of the latch 6 coaxially passes through the tension spring 7 and penetrates the ear. A limiting cap is fixed at one end of the latch 6 located outside the ear. The limiting cap abuts against one end of the tension spring 7 away from the hole 101. The latch 6 penetrates one end of the ear. A protrusion 601 is fixedly connected to the side wall, a socket 401 matching the latch 6 is provided on the side of the second connecting plate 4, and a slide groove 404 matching the protrusion 601 is provided on the side wall of the socket 401, an annular groove 402 connected to the slide groove 404 is provided on the side wall at the bottom of the socket 401, the protrusion 601 is rotatably engaged and snap-fitted in the groove 402, and a receiving opening 102 matching the protrusion 601 is provided on the side of the ear away from the limiting cap.

[0040] Principle: The first end plate 1, the first connecting plate 2, the second end plate 3, the second connecting plate 4, the tension spring 7 and the latch 6 form an inseparable whole, which is not easy to be lost or fall into some narrow gaps in space.

[0041] Open the cable clamp: drive the latch 6 to rotate through the limit cap, when the protrusion 601 is aligned with the slide groove 404, the tension spring 7 pushes the limit cap away from the first end plate 1, the limit cap drives the latch 6 to move synchronously, the latch 6 drives the protrusion 601 to move synchronously, the protrusion 601 slides through the slide groove 404 and enters the receiving port 102, then the second connecting plate 4 can be opened; close the cable clamp; at this time, under the action of the tension spring 7, the protrusion 601 is located in the receiving port 102, the second connecting plate 4 is placed on the first end plate 1, the slide groove 404 is aligned with the receiving port 102, the latch 6 is pushed, the protrusion 601 enters the groove 402, and the latch 6 is rotated (that is, the protrusion 601 is staggered with the slide groove 404), and the protrusion 601 is engaged with the groove 402. In summary, the opening and closing process of the utility model is simple and easy to operate, so it is easy to install and replace.

[0042] Example 3

[0043] Embodiment 3 is implemented on the basis of embodiment 2. Compared with embodiment 2, this embodiment can limit the latch 6 to prevent it from rotating randomly, and avoid the protrusion 601 and the slide groove 404 from aligning when the latch 6 rotates randomly, causing the cable clamp to open automatically.

[0044] like Fig.11 and 12 As shown, a limiting groove 403 matching with the protrusion 601 is formed on the side wall of the groove 402 close to the support ear, and the protrusion 601 is snap-fitted into the limiting groove 403 .

[0045] Principle: By limiting the position of the protrusion 601 through the limiting groove 403, the latch 6 cannot rotate at will, thus avoiding the phenomenon of the cable clamp opening automatically.

[0046] Open the cable clamp: first push the latch 6 inward, then the protrusion 601 will escape from the limiting groove 403, driving the latch 6 to rotate. When the protrusion 601 is aligned with the slide groove 404, the tension spring 7 pushes the limiting cap away from the first end plate 1, the limiting cap drives the latch 6 to move synchronously, the latch 6 drives the protrusion 601 to move synchronously, the protrusion 601 slides through the slide groove 404 and enters the accommodating opening 102, and the second connecting plate 4 can be opened; close the cable clamp; at this time, under the action of the tension spring 7 The protrusion 601 is located in the receiving opening 102 by forcing, and the second connecting plate 4 is placed on the first end plate 1, so that the slide groove 404 is aligned with the receiving opening 102, and the latch 6 is pushed. After the protrusion 601 enters the groove 402, the latch 6 is rotated. When the protrusion 601 is aligned with the limiting groove 403, the tension spring 7 pushes the limiting cap away from the first end plate 1, and the limiting cap drives the latch 6 to move synchronously, and the latch 6 drives the protrusion 601 to move synchronously, and the protrusion 601 slides into the limiting groove 403. In summary, the opening and closing process of the utility model is simple and easy to operate, so it is easy to install and replace.

[0047] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
