Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1 to 3, the present invention includes a rotary hook 1;

an opening 2 opened on the surface of the rotating shuttle 1;

the positive fixedly connected with axostylus axostyle 3 of rotating shuttle 1, the surface cover of axostylus axostyle 3 is equipped with squeeze stem 4, and squeeze stem 4 can be rotatory on the surface of axostylus axostyle 3, and the one end that the axostylus axostyle 3 was kept away from to squeeze stem 4 extends to the front of opening 2.

Referring to fig. 3, the surface of the shaft lever 3 is sleeved with a torsion spring 5, and the front end and the rear end of the torsion spring 5 are in contact with the surface of the pressing rod 4 and the surface of the rotary hook 1, respectively.

This embodiment can support the extrusion pole 4 through setting up the torsional spring 5, makes the extrusion pole 4 possess the effect that resets, improves the fixed stability of extrusion pole 4.

Referring to fig. 2, a groove 6 is formed in the back surface of the extrusion rod 4, and a support roller 7 is movably connected to the inside of the groove 6 through a pin.
