The utility model discloses further set up to: the bottom end of each clamping groove is provided with a sliding groove which enables the two clamping blocks to be close to or far away from each other, and each clamping block is provided with a second sliding block which slides along the sliding groove.

Through adopting above-mentioned technical scheme, the clamp splice can slide along the spout and follow the tight material of good clamp under the effect that promotes the subassembly, and the material can not appear breaking away from the clamp splice.

The utility model discloses further set up to: and the clamp body is provided with a limiting block for compressing the clamping block.

Through adopting above-mentioned technical scheme, the clamp splice can not break away from the double-layered groove when sliding, the tight material of clamp that simultaneously can be more stable.

The utility model discloses further set up to: and one side of the clamp body is provided with a mounting seat.

Through adopting above-mentioned technical scheme, conveniently be fixed in tensile machinery with anchor clamps.
