A guide rod 113 is provided at both the upper and lower ends of the width branch pipe 11, and the two guide rods 113 are respectively passed through the upper and lower ends of the sliding ring 111 by clearance fit. A rotating rod 114 is welded to the left end of the worm 112. The rotating rod 114 is located on the right side surface of the base frame 1. The rotating rod 114 passes through the internal pipe 116, and the internal pipe 11 6 is provided with a ball 117 to assist the rotation of the rotating rod 114, an adjusting support rod 12 is also slidably installed inside the left end of the base frame 1, and an extension rod 121 is rotatably installed inside the lower end of the adjusting support rod 12, a positioning hole 122 is penetrated inside the adjusting support rod 12, a limit shell 13 is also provided on the upper surface of the base frame 1, a pull button 131 is installed on the upper end of the limit shell 13, and a spring rod 132 is welded at the bottom of the pull button 131, the upper end of the spring rod 132 is clearance-fitted through the upper end of the limit shell 13, the lower end of the spring rod 132 is connected with a latch 133, and the latch 133 is plugged and installed in the positioning hole 122, and a lower push plate 123 is also provided at the right end of the adjusting support rod 12, and the right end of the lower push plate 123 is inclined to face the right end of the base frame 1 The lifting roller 124 of the upper part is squeezed downward, and a moving wheel 1241 is connected to the outer side of the lifting roller 124, and a positioning shaft 1242 is fixed to the outer axis of the moving wheel 1241, and the positioning shaft 1242 is slidably installed on the inner side of the guide rail 1244 on the inner wall of the bottom frame 1, and a support block 1243 is also provided inside the guide rail 1244 to support the positioning shaft 1242 for rotation, and a top spring 1245 is welded between the bottom of the support block 1243 and the bottom of the guide rail 1244. In the present invention, before training, the width between the two bottom frames 1 can also be adjusted according to needs. When adjusting, the worm 112 is driven to rotate by rotating the rotating rod 114. Under the connection of the connecting long rod 115, the two worms 112 with opposite threads rotate synchronously, driving The two sliding rings 111 slide in opposite directions to adjust the distance between the two width branches 11. During the adjustment process, the two width branches 11 are telescopically connected through the built-in tube 116, so as to adjust the width between the two base frames 1. The adjustment is made according to the athletes in different training to improve the training effect of different athletes. At the same time, the extension rod 121 at the bottom of the adjustment support rod 12 is rotated outward to form an extended support structure on both sides of the adjustment support rod 12, thereby increasing the support range of the adjustment support rod 12 on the ground, thereby improving the stability of the adjustment support rod 12 placed on the runway and avoiding the hurdle frame from tipping over during training. When the hurdle frame needs to be stored after training, the adjustment support rod 12 is retracted into the base frame 1, and the adjustment support rod 12 is retracted and fixed by the positioning rod 235.The exposed part of the adjusting support rod 12 on the rear side of the base frame 1 can be plugged into the front end of the next base frame 1, and the previous adjusting support rod 12 can be plugged and fixed through the positioning plug rod 235 on the side of the front end of the next base frame 1, so that the base frames 1 and the adjusting support rods 12 on multiple hurdles are connected, fixed, and neatly arranged for storage, avoiding the deformation and damage of the components caused by random stacking of the hurdles. At the same time, when the adjusting support rod 12 is retracted into the lower base frame 1, the push plate 123 is driven to squeeze the lifting roller 124 downward, and the moving wheel 1241 descends, which can play an auxiliary movement effect at the bottom of the base frame 1, which is convenient for the movement and storage of the hurdles.

[0021] A preferred technical solution, the worm 112 is provided with two, and a connecting long rod 115 is provided between the two worms 112, and the two worms 112 with opposite threads are synchronously rotated by connecting the long rod 115, driving the two sliding rings 111 to slide in opposite directions, and adjusting the spacing between the two width branch pipes 11, thereby adjusting the width between the two base frames 1, and adjusting according to different athletes in training to improve the training effect of different athletes. While adjusting, the two upper sponge rods 214 are telescoped inside the two horizontal tubes 21, and cooperate with the elastic squeezing of the telescopic hose 212 to ensure that the two sponge rods 214 are always connected to form a cross bar following the adjustment when the width of the hurdle is adjusted; A preferred technical solution, three positioning holes 122 are arranged inside the adjusting support rod 12, and when the adjusting support rod 12 is slidably adjusted inside the left end of the base frame 1, the latch 133 is inserted into the positioning hole 122 to telescopically adjust and fix the adjusting support rod 12 inside the left end of the base frame 1, and when the hurdles need to be stored, the base frames 1 and the adjusting support rods 12 on the two hurdles can be connected, snapped, fixed, and neatly arranged for storage, so as to avoid deformation and damage of components caused by random stacking of the hurdles. Two extension rods 121 are arranged, and are respectively installed on both sides of the adjusting support rod 12. The extension rods 121 on both sides are rotated outward to form an extended support structure on both sides of the adjusting support rod 12, thereby increasing the support range of the adjusting support rod 12, thereby improving the stability of the adjusting support rod 12 placed on the runway, and avoiding the hurdle from tipping over. A preferred technical solution is that there are two moving wheels 1241, and they are respectively arranged at both ends of the lifting roller 124. When the adjusting support rod 12 is retracted into the lower frame 1, the pushing plate 123 is driven to squeeze the lifting roller 124 downward, and the moving wheel 1241 drops. At this time, it can play an auxiliary movement effect at the bottom of the frame 1, which is convenient for the movement and storage of the hurdle. When the adjusting support rod 12 is moved out of the lower frame 1 for training, the pushing plate 123 loses the downward pressure on the lifting roller 124, and the upward elastic force applied by the top spring 1245 at the bottom of the guide rail 1244 drives the positioning shaft 1242 and the moving wheel 1241 to be lifted up and retracted into the frame 1, so as to avoid the moving wheel 1241 causing the frame 1 to be displaced during training, thereby improving the stability of the training hurdle placement and ensuring the safety of training.
