Further, the protection machanism 6 is provided with two sets ofly, and hollow section of thick bamboo 61 is the slope form setting, and damping spring 62 is located hollow section of thick bamboo 61's inside, can adjust the rate of tension when preventing the broken string of silk thread through the setting of two sets of protection machanism 6, and can prevent through the setting of slope form that the silk thread from contacting the incoming line mouth of seting up to mounting bracket 14.

The working principle is as follows: when the silk thread needs to be clamped and fixed, firstly, the knob 32 is rotated clockwise, the knob 32 is rotated to drive the first connecting rod 31 to rotate, the first connecting rod 31 is rotated to drive the ratchet ring 22 to rotate, the ratchet ring 22 is rotated to drive the inner ring 23 to rotate, the inner ring 23 is rotated to drive the ratchet main body 25 to rotate, the ratchet main body 25 is rotated to drive the threaded screw rod 51 to rotate through the rotating rod 24, the threaded screw rod 51 is rotated to drive the screw rod sleeve 52 to move through the fixed rod 54 and the slideway 55, and the screw rod sleeve 52 is moved to drive the thread clamping piece 16 to move through the third connecting rod 53, so that the silk thread can be clamped through the moved thread clamping piece 16;

when the tension of the wire needs to be adjusted, by rotating the knob 32 counterclockwise, when the knob 32 rotates counterclockwise, the driven wheel 34 is driven to rotate through the first connecting rod 31, when the driven wheel 34 rotates, the hinge rod 35 is driven to perform circular motion, when the hinge rod 35 performs circular motion, the triangular disc 36 is pulled to rotate around the bottom end, when the triangular disc 36 rotates, the pulling teeth 37 are pulled to move, when the pulling teeth 37 move, due to the original position of the hinge rod 35 rotating back again, the rotating gear 313 can be driven to rotate through the pulling teeth 37, when the rotating gear 313 rotates, the threaded rod 41 is driven to rotate through the driving rod 312, when the threaded rod 41 rotates, the threaded sleeve 42 is driven to rotate, when the threaded sleeve 42 rotates, the rotating sleeve 43 is driven to move through the sliding block 44 and the sliding rail 45, when the rotating sleeve 43 moves, the sliding rod 47 and the wire tension wheel 48 are driven to move, so that the length of the thread hanging on the thread tensioning wheel 48 can be adjusted.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
