[0018] Among them, a groove 5 is provided at the top of the first connecting rod 1. After the connecting sleeve 7 is installed between the first connecting rod 1 and the second connecting rod 2, it corresponds to the position of the groove 5. A connecting column 15 is fixedly connected to the bottom of the first connecting rod 1. A through hole 6 is provided on the second connecting rod 2 to match the connecting column 15. After the connecting column 15 is inserted into the through hole 6, the first connecting rod 1 and the second connecting rod 2 can be pre-fixed, and the size of the connecting column 15 matches the through hole 6, which facilitates stable docking between the first connecting rod 1 and the second connecting rod 2.
[0019] Among them, the connecting sleeve 7 is fixedly connected to the plug block 8, and the plug block 8 is fixedly connected to the threaded rod 9. The thread of the threaded rod 9 is set at the upper half end. The inner sides of the connecting sleeve 7 are symmetrically fixedly connected with the plug sleeves 10. A fixing hole 11 is enclosed between the two plug sleeves 10. The bottom of the torsion plate 14 is fixedly connected with a plug column 12, and the plug column 12 can be inserted into the fixing hole 11.
