[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Refer to Figures 1-4 , a durable nylon zipper that is convenient to use, including a zipper head 1, a pull ring 3 and a zipper rod 4. The pull ring 3 is arranged on the surface of the zipper head 1, and the zipper rod 4 is movably sleeved on the surface of the pull ring 3. The zipper head 1 includes two rotating heads 112 and a moving head 111. The two rotating heads 112 are respectively rotatably connected to both sides of the moving head 111. A reinforcing rod 2 is fixedly installed on the surface of the moving head 111. Sliding grooves are provided on the surfaces of the moving head 111 and the rotating head 112. Through holes are provided on the side wall of the reinforcing rod 2 at positions corresponding to the sliding grooves. An insert rod 5 is arranged on the surface of the sliding groove. The insert rod 5 penetrates through the through hole on the surface of the reinforcing rod 2. A thickening block 8 is fixedly installed on the top of the reinforcing rod 2. A screw rod 10 is threadedly penetrated through the surface of the thickening block 8. The surface of the screw rod 10 penetrates through the reinforcing rod 2. A turning handle 9 is fixedly installed at the top end of the screw rod 10.

[0024] This solution has the following working process:

[0025] During use, when the zipper clamps the two-sided base cloth, first use the turning handle 9 to rotate the screw rod 10. When the screw rod 10 rotates inside the thickening block 8, it will move upward, so that the round block 11 moves away from the round groove on the surface of the insert rod 5. At this time, the insert rod 5 is pulled out, so that the rotating head 112 and the moving head 111 can rotate without the restriction of the insert rod 5, so that the rotating head 112 that clamps the base cloth can be turned outwards, which is convenient to take out the clamped base cloth. To use the zipper head 1 normally, the rotating head 112 needs to be restricted. When restricting, directly insert the insert rod 5 into the sliding groove on the surface of the rotating head 112 and the through hole on the surface of the reinforcing rod 2, so that the rotating head 112 cannot rotate with the moving head 111 under the restriction of the insert rod 5, and then the entire zipper head 1 can be used normally.

[0026] According to the above working process, it can be known that:

[0027] By setting structures such as the insert rod 5, the rotating head 112, the screw rod 10 and the fixed rod 6, it is convenient to disassemble the entire zipper head 1, so as to facilitate taking out the clamped base cloth and prevent the situation of getting stuck during use.

[0028] Further, a round block 11 is rotatably connected to one end of the screw rod 10 away from the handlebar 9. A round groove adapted to the size of the round block 11 is formed on the surface of the insertion rod 5. By contacting and squeezing between the round block 11 and the round groove, and the round block 11 and the screw rod 10 are rotatably connected, so that friction between the screw rod 10 and the round groove will not occur, causing damage to the insertion rod 5.

[0029] Further, a fixing rod 6 is fixedly installed on the surface of the rotating head 112 relative to the position of the sliding groove. The fixing rod 6 is in an "n" shape structure. The insertion rod 5 is located between the two arms of the fixing rod 6, and the stability between the rotating head 112 and the moving head 111 is enhanced by the fixing rod 6.

[0030] Further, an extension rod 14 is slidably inserted into one end of the zipper rod 4 away from the pull ring 3. A spring 12 is fixedly installed at the port of the extension rod 14 located inside the zipper rod 4. One end of the spring 12 away from the extension rod 14 is fixedly connected to the zipper rod 4. The extension rod 14 and the spring 12 are used to facilitate pulling the zipper head 1, and also facilitate hiding the extension rod 14, enhancing the aesthetics.

[0031] Further, limiting blocks 13 are fixedly installed on both sides of the extension rod 14 near the spring 12. The limiting blocks 13 can limit the extension rod 14 from disengaging from the inside of the zipper rod 4.

[0032] Further, a rubber sleeve 7 is fixedly installed at one end of the extension rod 14 away from the spring 12. The rubber sleeve 7 serves to increase friction.

[0033] In summary, when the zipper clamps the two side base fabrics during use, first rotate the rotary handle 9 to rotate the screw rod 10. When the screw rod 10 rotates inside the thickening block 8, it will move upward, so that the round block 11 moves away from the round groove on the surface of the insertion rod 5. At this time, pull out the insertion rod 5, so that the rotating head 112 and the moving head 111 can rotate without the restriction of the insertion rod 5, and then the rotating head 112 clamping the base fabric can be turned outwards, which is convenient for taking out the clamped base fabric. For the zipper head 1 to be used normally, the rotating head 112 needs to be restricted. When restricting, directly insert the insertion rod 5 into the chute on the surface of the rotating head 112 and the through hole on the surface of the reinforcing rod 2, so that the rotating head 112 cannot rotate with the moving head 111 under the restriction of the insertion rod 5, and then the entire zipper head 1 can be used normally. By rotating the rotary handle 9, the rotary handle 9 drives the screw rod 10 to rotate. When the screw rod 10 rotates, it moves downward, so that the round block 11 is squeezed against the round groove, and then the insertion rod 5 can fix the rotating head 112 and the moving head 111 better under pressure, which is convenient for the normal use of the zipper head 1. The fixing rod 6 can further serve the purpose of restricting the insertion rod 5 and indirectly serve the purpose of fixing the moving head 111 and the rotating head 112. The longer the length of the zipper rod 4 during use, the more convenient it is to pull, but if the zipper rod 4 is too long, it will affect the beauty of the zipper. At this time, the reinforcing rod 2 is slidably inserted at the bottom end of the zipper rod 4. When pulling, directly pull the extension rod 14. After the extension rod 14 moves outwards, it is restricted by the limit block 13, which is convenient for pulling the zipper head 1. When it is not necessary to pull, the reinforcing rod 2 retracts into the zipper rod 4 under the action of the spring 12, so as not to affect its beauty. The rubber sleeve 7 plays an anti-slip role. By setting structures such as the insertion rod 5, the rotating head 112, the screw rod 10 and the fixing rod 6, it is convenient to disassemble the entire zipper head 1, so as to facilitate the removal of the clamped base fabric and prevent the situation of jamming during use. By setting structures such as the extension rod 14, the spring 12 and the limit block 13, it is convenient to extend the zipper rod 4 during use. When not in use, the extension rod 14 can be hidden, which is convenient for use and does not affect the beauty degree.
