[0027] The diameter of the ball 5 is larger than the diameter of the rope hole 4 , so the ball 5 will not fall out of the rope hole 4 .

[0028] The utility model also discloses a method for adjusting the length of a rope, which uses the rope length adjustment buckle as described above to adjust the length of the rope, and the adjustment method comprises the following steps:

[0029] Step 1: When it is necessary to pull rope A to the left side of housing 1 to adjust the length of rope A on the left side of housing 1, that is, to increase the size of rope ring B on the left side of housing 1, first press the ball stop rod 8, pull rope A to the left side of housing 1, that is, pull rope A to the direction of rope ring B. If the pulling is smooth, just pull rope A to the required position. If rope A cannot be pulled, release the ball stop rod 8, first pull rope A to the right side of housing 1, so that ball 5 moves to the right end of raceway 6 under the drive of rope A, until rope A cannot be pulled, press the ball stop rod 8 again to stop ball 5 from moving to the left end of raceway 6, and then pull rope A to the left side of housing 1. At this time, rope A is pulled smoothly until rope A is pulled to the required position, release the ball stop rod 8, and complete the process of adjusting the length of rope A to the left side of housing 1.

[0030] Step 2: When it is necessary to pull rope A to the right side of housing 1 to adjust the length of rope A on the right side of housing 1, that is, to reduce the size of rope ring B on the left side of housing 1, first press the ball stop rod 8, pull rope A to the right side of housing 1, that is, pull rope A to the direction of free end C. If the pulling is smooth, just pull rope A to the required position. If rope A cannot be pulled, release the ball stop rod 8, first pull rope A to the left side of housing 1, so that ball 5 moves to the left end of raceway 6 under the drive of rope A, until rope A cannot be pulled, press the ball stop rod 8 again to stop ball 5 from moving to the right end of raceway 6, and then pull rope A to the right side of housing 1. At this time, rope A is pulled smoothly until rope A is pulled to the required position, release the ball stop rod 8, and complete the process of adjusting the length of rope A to the right side of housing 1.

[0031] The adjustment method also includes the step of installing the rope fixing block 7 before adjusting the length of the rope A, which step includes: first moving the ball 5 to the right end of the raceway 6, then passing the positioning end of the rope A through the rope hole 4 through the housing 1, and then fixing the positioning end of the rope A with the rope fixing block 7 together, and then installing the rope fixing block 7 with the positioning end of the rope A fixed into the rope fixing block mounting hole 9 of the housing 1, and the left end of the sliding rod 121 is inserted into the lock hole 71, and the rope fixing block 7 cannot be removed from the rope fixing block mounting hole 9.

[0032] The adjustment method also includes the step of removing the rope fixing block 7, which includes: when necessary, pushing the push rod 122 to the right, the sliding rod 121 moves to the right position along the locking rod mounting hole 13, and after the left end of the sliding rod 121 leaves the rope fixing block mounting hole 9, the rope fixing block 7 can be removed from the rope fixing block mounting hole 9.

[0033] The above adjustment method is simple and practical. After the rope A is adjusted, it is locked in the raceway 6 of the housing 1 by the ball 5. The more the rope A is pulled, the greater the locking force is, and the rope A is less likely to move, thereby improving the stability and safety of the product.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
