[0032] Specifically, there is a workbench 8 below the fixed seat 11; a support bar 10 for carrying the chip 9 is fixedly installed on the workbench 8; the fixed seat 11 is fixedly connected to the workbench 8.

[0033] The principle and beneficial effects of the above technical solution:

[0034] In a specific implementation, the fixed rod 1 is connected to the fixed seat 11, then the fiber optic cable 5 is passed through the clamping hole 4 from one side of the fixed seat 11 and the fiber optic cable 5 passes through the gap, and then the fiber optic cable 5 is connected to the chip 9 through a fiber optic connector, such as SC, LC, ST, FC, etc. After that, the tightening member 3 is threadedly connected to the tightening hole 7, and one end of the tightening member 3 can push one of the deformation strips 6 towards the other deformation strip 6, so that the gap between the two deformation strips 6 is reduced until the fiber optic cable 5 is clamped; thus, the clamping and positioning of the fiber optic cable 5 are realized.

[0036] In this embodiment, asFigure 3 As shown, the two deformation bars 6 are symmetrical and fixedly connected to the fixed rod 1; specifically, the two deformation bars 6 are fixedly connected to one end of the fixed rod 1 away from the fixed seat 11; the opposite sides of the two deformation bars 6 each have an arc surface, and the two arc surfaces are coaxial; the inner ring wall of the sleeve 2 is in sliding contact with both of the arc surfaces.

[0037] Principle and beneficial effects of the above technical solution:

[0038] During specific implementation, the sleeve 2 is slidably sleeved on the two deformation bars 6, and the threaded hole is aligned with one of the deformation bars 6, and then the tightening member 3 is threadedly connected into the tightening hole 7, so that one end of the tightening member 3 can push one of the deformation bars 6 towards the other deformation bar 6, and the two deformation bars 6 clamp the optical fiber line 5 at the gap.

[0039] In this embodiment, as Figure 2 、 4 shown, a connecting rod 12 is provided at one end of the fixed rod 1 away from the deformation part; one end of the connecting rod 12 is coaxially and fixedly connected to the fixed rod 1; the connecting rod 12 is detachably connected to the fixed seat 11; a connecting hole 13 is formed inside the connecting rod 12; the connecting hole 13 communicates with the clamping hole 4.

[0040] Principle and beneficial effects of the above technical solution:

[0041] During specific implementation, the fixed rod 1 can be detachably connected to the fixed seat 11 through the connecting rod 12, so it is more convenient and fast during installation and replacement. This makes the maintenance and adjustment of the clamping device simpler, saving time and labor costs.

[0042] Embodiment Two: On the basis of Embodiment One, as Figure 1 shown, the circumferential side of the connecting rod 12 has a threaded surface; a horizontal threaded hole is formed on the fixed seat 11; the connecting rod 12 is threadedly connected into the threaded hole.

[0043] Principle and beneficial effects of the above technical solution:

[0044] During specific implementation, through threaded connection, the connecting rod 12 can be firmly fixed on the fixed seat 11, not easily loosened or swung, ensuring the stability of the clamping device; by rotating the connecting rod 12, the distance between the connecting rod 12 and the fixed seat 11 can be adjusted to meet the clamping requirements of different sizes; the threaded connection design enables the connecting rod 12 to be easily inserted into the threaded hole of the fixed seat 11, quickly completing the installation process and reducing the installation time and working intensity.

[0045] Embodiment Three: On the basis of Embodiment One, asFigure 5 As shown, a horizontal sliding hole is provided on the fixing seat 11; the connecting rod 12 is clamped in the sliding hole, and one end of the connecting rod 12 passes through the side of the fixing seat 11 away from the deformation portion; a clamping hole 15 is provided on the connecting rod 12; the clamping hole 15 passes through the connecting rod 12; the clamping hole 15 is staggered with the connecting hole 13; a clamping part is detachably connected in the clamping hole 15.

[0046] The principle and beneficial effects of the above technical solution:

[0047] In specific implementation, the fixing rod 1 is clamped in the sliding hole through the connecting rod 12 , and one end of the connecting rod 12 is passed through the side of the fixing seat 11 away from the deformation portion, and then the clamping piece is clamped in the clamping hole 15 .

[0048] The fixing rod 1 and the connecting rod 12 are connected by a clamping method, which makes installation and disassembly very convenient and quick.

[0049] In this embodiment, Figure 6 As shown, the clamping member includes a clamping frame 14 ; the clamping frame 14 has a notch; the clamping frame 14 has a clamping pin 16 ; the clamping frame 14 is clamped in the clamping hole 15 via the clamping pin 16 .

[0050] Specifically, Figure 6 As shown, the shape of the card frame 14 is U-shaped, and the card frame 14 includes a horizontal bar and two card pins 16 vertically fixedly connected to the horizontal bar; a gap is formed between the two card pins 16; the number of the card holes 15 is two; each card pin 16 is carded with the corresponding card hole 15.

[0051] The principle and beneficial effects of the above technical solution:

[0052] The design of the U-shaped clamping frame 14 makes the clamping pins 16 relatively stable after being fixed on the horizontal bar. This structure can provide better support and ensure the firmness and stability of the connection.

[0053] In this embodiment, Figure 5 As shown, one side of the clamping frame 14 contacts a side of the fixing seat 11 away from the deformation portion.

[0054] Specifically, the vertical side of the clamping frame 14 contacts the side of the fixing seat 11 away from the deformation portion; and the end of the fixing rod 1 close to the connecting rod 12 abuts against the fixing seat 11 .

[0055] The principle and beneficial effects of the above technical solution:

[0056] During specific implementation, the clamping frame 14 restricts the position of the connecting rod 12 from one side of the fixed seat 11, while the fixed rod 1 restricts the position of the connecting rod 12 from the other side of the fixed seat 11. This prevents the connecting rod 12 from sliding within the sliding hole after the clamping frame 14 is installed, thereby improving the stability.

[0057] Embodiment 4: On the basis of Embodiment 1, as Figure 2 shown, the inner diameter of the sleeve 2 is smaller than the diameter of the fixed rod 1.

[0058] Specifically, the inner diameter of the sleeve 2 is shorter than the diameter of the fixed rod 1.

[0059] Principle and beneficial effects of the above technical solution:

[0060] During specific implementation, since the inner diameter of the sleeve 2 is shorter than the diameter of the fixed rod 1, the sleeve 2 can only slide on the deformation part, causing one end of the sleeve 2 to abut tightly against the end of the fixed rod 1. This can effectively fix the position of the sleeve 2 and prevent the sleeve 2 from sliding along the fixed rod 1 during the connection process, improving the stability and reliability of the connection.

[0061] In this embodiment, as Figure 3 shown, rubber pads 17 are respectively connected to the opposite side walls of the deformation strip 6; there is a gap between the two rubber pads 17; and the gap communicates with the clamping hole.

[0062] Specifically, the rubber pads 17 are adhesively bonded to the opposite side walls of the deformation strip 6.

[0063] Principle and beneficial effects of the above technical solution:

[0064] The setting of the rubber pads 17 can reduce the original distance between the two deformation strips 6. Thus, when the pressing member 3 presses tightly, it can make it easier for the two deformation strips 6 to clamp the optical fiber wire 5 through the two rubber pads 17. At the same time, the rubber material has good cushioning performance, which can reduce the pressure and friction on the optical fiber wire 5 and effectively protect the optical fiber wire 5 from damage.

[0065] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in terms of form and details without departing from the scope defined by the claims of the present invention.
