[0003] However, the fixing mode of the prior art is to fix the two by glue, and the flyer guide tube will fall off due to the decrease of the viscosity of the glue due to the increase of the ambient temperature, affecting the production efficiency. In order to increase the bonding strength of the flyer support and the flyer porcelain tube as much as possible, it is necessary to increase the contact area of the flyer support and the flyer porcelain tube as much as possible, so that the matching degree of the size of the flyer support and the flyer porcelain tube is required to be high.

[0004] In order to solve the above problems, the prior art also tries to weld a connecting rod between the two U-shaped rods on the flyer support to increase the clamping force of the flyer support on the flyer guide tube, so that the distance between the two U-shaped rods of the support is smaller, so as to increase the clamping force. However, it is found through tests that the flyer support is more prone to deformation and fracture after welding due to the small diameter of the connecting rod.

[0005] Therefore, it is of great significance to research an adjustable type double twister flyer fixing device to solve the above problems. INVENTION CONTENTS
