Referring to fig. 6, the first and second bevel gears 5 and 9 are limited in rotation on the support frame 6 by penetrating the support frame 6 through the first and second rotation pipes 22 and 23.
Referring to fig. 1, by symmetrically arranging two limiting plates 15 on the rotating ring 14, the stress of the rotating ring 14 is more balanced and can be more stable during movement.
Referring to fig. 6, by the synchronous rotation of the rotating friction wheel 24 of the rotating tube one 22, the recording paper 4 tangent to the bottom of the friction wheel 24 is moved by the friction force generated when it contacts the friction wheel 24, so that the scribing pen 3 can perform a dynamic scribing operation on the moving recording paper 4.
Through the cooperation between the above-mentioned structure and use, solved in the in-service use, because also be difficult to in the current device carry out abundant detection to the bending resistance characteristic of fabrics under the change torsion degree, bring inconvenient problem for the use.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
