Second embodiment

Referring to fig. 6-7, a second embodiment of the present application provides another multi-protection pulling mechanism based on the multi-protection pulling mechanism provided in the first embodiment of the present application. The second embodiment is only the preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

Specifically, the multiple-protection pulling mechanism provided by the second embodiment of the present application is different in that: two sides of the inner wall of the U-shaped support 9 are both provided with locking grooves 11, a T-shaped clamping block 12 is connected between two sides inside the locking grooves 11 in a sliding manner, and clamping grooves 13 matched with the T-shaped clamping blocks 12 are both arranged on two sides of the anti-rolling hairbrush 10;

when the anti-rolling brush 10 contacts the bottom of the inner wall of the U-shaped support 9, the T-shaped clamping block 12 and the clamping groove 13 are on the same straight line, so that clamping and fixing are facilitated.

One side of the T-shaped clamping block 12 penetrates through the locking groove 11 in sequence and extends to the inside of the clamping groove 13.

A limiting spring 14 is arranged on the other side of the T-shaped clamping block 12, and one end of the limiting spring 14 is arranged on one side inside the locking groove 11;

the limiting spring 14 is arranged, and in rebounding, the T-shaped clamping block 12 and the clamping groove 13 are pushed to be clamped and fixed, so that the firmness of installation of the anti-rolling brush 10 is improved.

Rubber pads 15 for buffering are arranged on two sides of the inner wall of the U-shaped support 9;

through the arranged rubber pad 15, when the anti-rolling brush 10 is extruded, the anti-rolling brush deforms, so that the tensile force is buffered, and the yarn is prevented from being broken directly under the action of the tensile force;

and the rubber pad 15 is arranged, so that the U-shaped bracket 9 has a certain mounting gap, and the extruded anti-rolling hairbrush 10 is convenient to buffer.

By means of the provided anti-curl brush 10, the yarn is prevented from being caught in the rod 3 to cause yarn entanglement, by blocking the yarn in use. When the shut down appears in the yarn, can receive the too big pulling force of dynamics, extrude preventing rolling up brush 10, because the mounting means who prevents rolling up brush 10 generally is fixed for the joint, consequently in extrusion process, drops easily, and then loses stopping to the yarn, makes the yarn be drawn into in the roller rod 3 easily, causes the winding of yarn to the degree of difficulty of later stage maintenance has been increaseed.

When preventing rolling up brush 10 in the installation, through exerting pressure on preventing rolling up brush 10, the drive is prevented the bottom of rolling up brush 10 and is inserted U type support 9's inside, until extruding T type joint piece 12, thereby contact the bottom of U type support 9 inner wall, wherein, at the extrusion in-process, make T type joint piece 12 slide and enter into the inside of joint groove 13, under spacing spring 14's resilience, promote it and enter into joint groove 13, it is fixed to accomplish the joint, improve the fastness of preventing rolling up brush 10 in use.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
