In addition, the yarn can be clamped to a certain extent in the yarn conveying process, so that the stable conveying state of the yarn can be maintained, and the conditions of falling off, deviation and the like of the yarn are avoided.

The thread clamp is provided with two pressing plates, the two pressing plates are mutually pressed by the spring, so that a certain clamping pressure applied to the yarn can be formed between the two pressing plates, and the stable conveying state of the yarn can be maintained. The clamping force of the thread clamp to the yarn is generally adjusted by adjusting the pressure of the spring through the nut, so that the pressure of the pressure plate to the yarn can be adjusted, and the transmission state of the yarn is maintained. The gap between the two pressing plates cannot be adjusted, and the two pressing plates are in a state of always abutting against each other; by adjusting the pressure of the springs, the pressure between the pressure plates can be adjusted only.

Different clamping states are needed for yarns with different types and thicknesses, for example, when the diameter of the yarn is smaller, two pressing plates are needed to be kept in a mutually pressed state, and a stable clamping effect is formed on the yarn; when the diameter of the yarn is thicker, particularly for thicker woolen yarns, the yarn is subjected to smaller pressure extrusion to clamp the yarn under a pressure state, so that friction damage to burrs outside the yarn due to excessive pressure is avoided; in addition, the partial thread clamp is required to enlarge the gap between the two pressing plates, form a relatively loose clamping state for the yarns, and further maintain smooth conveying and guiding of the yarns.
