[0027] In summary, the steplessly adjustable hanging beam drives the worm 103 to rotate by starting the servo motor 101, and then drives the first threaded rod 5 to rotate through the worm gear 104. During the rotation, the first threaded rod 5 drives the two movable beams 7 and the two hooks 13 to move in opposite directions through the two threaded sleeves 6, so as to adjust the distance between the two hooks 13, so that objects with different hanging point distances can be hoisted, thereby improving practicality. Secondly, by pulling the two pull rings 235 upward to drive the two sliders 231 and the two fixed blocks 232 to move upward, the two fixed blocks 232 are respectively moved out from the inside of the two fixed grooves 22, thereby releasing the position restriction of the two positioning blocks 17, and then the two positioning blocks 17 can be screwed. The two hand wheels 20 drive the two second threaded rods 19 to rotate, thereby driving the two positioning blocks 17 to move away from each other until the two positioning blocks 17 are respectively moved out from the inside of the two positioning holes 14, thereby releasing the fixation of the two connecting blocks 12. At this time, the two connecting blocks 12 are respectively pulled downward from the inside of the two connecting grooves 11, and the two hooks 13 can be removed, thereby facilitating the replacement of the hooks 13, solving the problem that in actual use of the existing hanging beam, the position of the hook installation on the hanging beam is mostly fixed, which makes it inconvenient to carry out lifting operations on objects with different lifting point spacings. Secondly, since the hooks are mostly fixedly installed and not easy to disassemble, it is inconvenient to replace the hooks after they are damaged, which is not conducive to use.
