[0030] The anti-slip mechanism 2 includes a mounting seat 21, which is fixedly connected to the mounting groove 4 of the chain head 1, a sliding groove 25 is provided in the middle of the mounting seat 21, an anti-sliding block 23 is slidably connected in the sliding groove 25, a connecting block 27 is fixedly connected to the inner side of the anti-sliding block 23, a spring 28 is fixedly connected to the middle of the connecting block 27, and a baffle 24 is fixedly connected to the middle of the mounting groove 4 on the inner side of the mounting seat 21;

[0031] The anti-slip mechanism 2 is set, and when the chain head 1 slides on the chain belt, the protruding part of the anti-slip block 23 will generate a certain pressure after the chain belt is filled into the chain head 1. The generated pressure will cause the anti-slip block 23 to slide into the sliding groove 25, because at this time it will drive the connecting block 27 to move into the movable groove 253, thereby compressing the spring 28. The compressed spring 28 itself will generate a reverse elastic force, thereby pushing the connecting block 27 out of the movable groove 253, thereby driving the anti-slip block 23 to push the sliding groove 25 out, so that the anti-slip block 23 and the chain teeth on the chain belt fit together, so that the chain head 1 will generate a certain resistance during the sliding process, thereby achieving an anti-slip effect. At the same time, because the arc-shaped anti-slip block 23 does not hinder the driving force applied to the chain head 1 by manpower, it can also achieve a good anti-slip effect when achieving normal use function, and will not cause damage to the chain belt due to its sharpness, so that the chain belt has a longer service life.

[0032] The baffle plate 24 is disposed inside the connecting block 27 and is used to prevent the anti-sliding block 23 from escaping from the sliding groove 25 .

[0033] The bottom of the chain head 1 is provided with first mounting holes 3 at both sides corresponding to the mounting groove 4 , and the mounting seat 21 is provided with second threaded holes 256 corresponding to the first mounting holes 3 .

[0034] A first screw 22 is provided between the mounting seat 21 and the zipper head 1. The first screw 22 passes through the first mounting hole 3 and is threadedly connected to the second threaded hole 256 of the mounting seat 21. The first screw 22 can facilitate the subsequent installation of the mounting seat 21, thereby facilitating the anti-slip effect of the zipper head 1.

[0035] Embodiment 2

[0036] See also Figure 1-7On the basis of the first embodiment, the sliding grooves 25 are further provided on both sides of the middle of the mounting seat 21, a movable groove 253 is provided between the sliding grooves 25, the mounting seat 21 is provided with an expansion groove 255 in the middle of the movable groove 253, and the mounting seat 21 is provided with a connecting groove 254 between the sliding groove 25 and the expansion groove 255.

[0037] The middle of the baffle 24 is arranged in the expansion slot 255 and the movable slot 253, and the two ends of the baffle 24 extend into the connecting slot 254. The mounting seat 21 has placement slots 252 on the upper and lower sides corresponding to the baffle 24. The mounting seat 21 has a first threaded hole 251 in the middle of the placement slot 252. A second screw 26 is arranged between the mounting seat 21 and the baffle 24. The second screw 26 passes through the baffle 24 and is threadedly connected to the first threaded hole 251.

[0038] A spring 28 is placed in the movable groove 253 , and the connecting block 27 is placed in the middle of the movable groove 253 and the expansion groove 255 . Both ends of the connecting block 27 pass through the connecting groove 254 and are fixedly connected to the anti-sliding block in the sliding groove 25 .

[0039] In actual operation, when this device is used, when the chain head 1 slides on the chain belt, a certain pressure will be generated because the protruding part of the anti-sliding block 23 is filled into the chain head 1 due to the chain belt. The generated pressure will cause the anti-sliding block 23 to slide into the sliding groove 25, because at this time it will drive the connecting block 27 to move into the movable groove 253, thereby causing the spring 28 to be compressed. The compressed spring 28 itself will generate a reverse elastic force, thereby pushing the connecting block 27 out of the movable groove 253, thereby driving the anti-sliding block 23 to push out of the sliding groove 25, so that the anti-sliding block 23 and the chain teeth on the chain belt fit together, so that the chain head 1 will generate a certain resistance during the sliding process, thereby achieving an anti-slip effect.
