[0036] The working principle and use process of the utility model are as follows: when the utility model is in use, the knob 57 is turned, and the rotation of the knob 57 drives the screw rod 51 to rotate. The screw rod 51 rotates through the screw hole 52 to drive the inner rod 53 to slide upward, thereby increasing the length of the secondary telescopic rod. The upward sliding of the inner rod 53 drives the slider 55 to slide inside the slide groove 58, thereby improving the stability of the inner rod 53 sliding upward. When the screw 51 rotates, it drives the limit block 563 to rotate inside the annular limit groove 562 inside the mounting sleeve 561, thereby avoiding the problem of relative sliding between the screw rod 51 and the outer rod 54. Pull the handle 47 to pull Pulling handle 47 drives center rod 46 to slide outward, and the outward sliding of center rod 46 drives limit plate 44 and fixing rod 43 to slide, compressing spring 45, and sliding fixing rod 43 out from the inside of fixing hole 41, and then holding handle 49 and rotating it, the rotation of handle 49 drives turntable 48 to rotate, the rotation of turntable 48 drives shaft 42 to rotate, and the rotation of shaft 42 drives sinker 6 to rise and fall.
