In this way, multiple groups of buffer spring pieces 12 can provide a primary buffer for the fixture, and the buffer force can be adjusted by tightening and loosening the nuts. Then, place the cable on the inner buffer clamping member 4 inside the lower clamping seat assembly 2, and after sleeving the upper mounting through holes 32 at both ends of the upper clamping seat assembly 3 with long bolts, make the inner buffer clamping member 4 inside the upper clamping seat assembly 3 fit above the cable. At this time, by screwing nuts on the two long bolts, the lower clamping seat assembly 2 and the upper clamping seat assembly 3 can be connected. At this time, the buffer elastic member 42 inside the inner buffer clamping member 4 is compressed, which can achieve a secondary buffer effect, and by tightening and loosening the nuts of the long bolts, it can adapt to different specifications of cables for buffer clamping work.
[0026] In some optional specific embodiments, such as Figure 2 As shown in the figure, the fixture buffer base assembly 1 includes a base mounting plate 10, elastic member insertion rods 11, buffer spring pieces 12, and base connection bolt rods 13.

The number of buffer spring pieces 12 is multiple groups, sleeved outside the elastic member insertion rods 11.

The lower clamping member mounting holes 23 are opened in the middle inside the upper part of the lower clamping seat body 20. Two sets of lower mounting through holes 24 are provided and opened through both ends inside the lower clamping seat body 20. By passing two long bolts through the lower part below the lower mounting through holes 24 at both ends inside the lower clamping seat assembly 2, the lower clamping seat assembly 2 is covered on the fixture buffer base assembly 1, so that the four base connection bolt rods 13 respectively pass through the four bolt rod mounting through holes 22 and are fixed by nuts.
[0028] In some alternative specific embodiments, as Figure 4 shown in the figure, the upper clamping seat assembly 3 includes an upper clamping seat body 30, upper clamping member mounting holes 31, and upper mounting through holes 32.

The buffer elastic member 42 is fixedly arranged inside the arc plate mounting hole seat 41. By screwing nuts onto the two long bolts, the lower clamping seat assembly 2 and the upper clamping seat assembly 3 can be connected. At this time, the buffer elastic member 42 inside the inner buffer clamping member 4 is compressed, which can achieve a secondary buffering effect, and by tightening and loosening the nuts of the long bolts, it can adapt to different specifications of cables for buffer clamping work.
[0030] Working principle of the present utility model: During use, the base mounting plate 10 is installed at the erection site through fixing bolts. After multiple groups of buffer spring pieces 12 penetrate through the elastic member insertion rods 11, first, two long bolts penetrate from below through the lower mounting through holes 24 at both ends inside the lower clamping seat assembly 2 to cover the lower clamping seat assembly 2 on the fixture buffer base assembly 1, so that the four base connection bolt rods 13 respectively penetrate through the four bolt rod mounting through holes 22 and are fixed by nuts. In this way, the multiple groups of buffer spring pieces 12 can provide a primary buffer for the fixture, and the buffer force can be adjusted by tightening and loosening the nuts. Then, the cable is placed on the inner buffer clamping member 4 inside the lower clamping seat assembly 2, and the upper mounting through holes 32 at both ends of the upper clamping seat assembly 3 are sleeved with long bolts, and the inner buffer clamping member 4 inside the upper clamping seat assembly 3 is attached above the cable.
