The turning handle 405 is fixedly installed on one end of the transmission rod 402. The plurality of meshing grooves 404 are arranged in a linear array on the side wall of the middle rod 301. The gear 403 is located between two of the support legs 401. The meshing teeth of the gear 403 match the shape of the meshing grooves 404, and the gear 403 meshes with the meshing grooves 404.

[0034] It should be noted that by providing the meshing grooves 404 on the outer side of the middle rod 301 and setting the gear 403 that can mesh with the meshing grooves 404, the provided turning handle 405 and transmission rod 402 are used to drive the gear 403 to rotate. Rotating the turning handle 405 drives the transmission rod 402 to rotate, and then the transmission rod 402 drives the gear 403 to rotate. The gear 403 then meshes with the meshing grooves 404 formed on the middle rod 301, so as to drive the middle rod 301 to move up and down on the support frame 2, assisting the user to press down or raise the middle rod 301, and improving the portability of use.

[0035] Working principle: When in use, first, lay the textile to be sampled flat on the base 1, then rotate the turning handle 405 to drive the transmission rod 402 to rotate, and then the transmission rod 402 drives the gear 403 to rotate. The gear 403 then meshes with the meshing grooves 404 formed on the middle rod 301 to drive the middle rod 301 to press down. First, the elastic spreading piece 307 at the bottom will contact the textile and press down and spread outwards to tighten the textile. Then, under the elastic action of the return spring 306, the pressing plate 305 presses down to cooperate with the base 1 to clamp the textile. The middle rod 301 continues to press down, so that the fixing plate 302 overcomes the elastic force of the return spring 306 to drive the sampling cutter head 303 to press down to sample the textile. After the sampling is completed, rotate the turning handle 405 in the reverse direction to raise the sampling cutter head 303 to complete the sampling of the textile.
