The connecting piece 202 supports the limit block 203 to snap into the corresponding limit hole 102 again through elasticity. At this time, the sliding cylinder 201 is fixed on the sleeve 101, realizing the adjustment of the telescopic length of the skipping rope handle. Through the design of setting the limit block 203 to snap into the limit hole 102 to fix the sliding cylinder 201, it is convenient to simplify the structure, improve the convenience of length adjustment, and make the device more portable and practical. When the length of the outer cord 207 of the handle needs to be adjusted, remove the four fixing bolts 304 respectively, remove the fastening piece 301 from the sliding cylinder 201, then pull the cord 207 to increase or decrease the proportion of its length in the sliding cylinder 201. After adjustment, snap the fastening piece 301 into the positioning groove 204 again. The fastening teeth 305 on the inner side of the fastening piece 301 clamp the cord 207 from both sides to fix the cord 207 to prevent it from loosening during the skipping process. Through the design of setting the detachable fastening piece 301, it is convenient to quickly adjust the length of the cord 207, further expand the use range of the device, and increase the use flexibility. Two fixing bolts 304 are screwed into the first screw hole 205 and the fourth screw hole 303 to reinforce the top of the fastening piece 301. The other two fixing bolts 304 are screwed into the second screw hole 206 and the third screw hole 302 to reinforce the side of the fastening piece 301, improving the installation reliability of the fastening piece 301 and the clamping stability of the cord 207.
