[0023] Specifically, the mounting mechanism 3 includes: a mounting groove 31, a hexagonal block 32, a rubber ring 33, a through hole 34, a limit groove 35, a button 36, a T-block 37, a spring 38, a hexagonal groove 39, a circular groove 310, a square groove 311, and a positioning plate 312. The top of the first rotating shaft 1 is provided with a mounting groove 31 to facilitate the bottom of the rotating shaft to be placed. The bottom of the mounting groove 31 is fixedly installed with a hexagonal block 32 to facilitate the hexagonal groove 39 to be placed so that the rotating shaft is fixed and cannot rotate. The inner wall of the mounting groove 31 A rubber ring 33 is fixedly installed to make the first rotating shaft 1 and the second rotating shaft 2 more tightly connected when docking. A through hole 34 is provided on the inner wall of the installation groove 31 to facilitate the installation of a button 36 so that the button 36 can slide in the through hole 34. A limiting groove 35 is provided on the inner wall of the through hole 34 to limit the button 36 to prevent it from falling off. The button 36 is slidably connected inside the limiting groove 35 to drive the T-block 37 to move toward the center of the rotating shaft. The button 36 is slidably connected to the through hole 34. The inner wall is convenient for the button 36 to move. A T-block 37 is fixedly installed at the bottom of the button 36, which can fix the spring 38 and also make the positioning plate 312 stuck. The left side of the T-block 37 is fixedly connected with a spring 38 to facilitate the reset of the T-block 37. Two groups of springs 38 are provided, and they are symmetrically distributed at the front and rear ends of the T-block 37 with a central symmetry axis of the front side of the T-block 37, which can better reset the T-block 37. The end of the spring 38 away from the T-block 37 is fixed to the mounting groove 31. On the inner wall, the spring 38 is conveniently fixed. A hexagonal groove 39 is provided at the bottom of the No. 1 rotating shaft 1, which can be conveniently inserted into the hexagonal groove 39. A circular groove 310 is provided at the bottom of the No. 1 rotating shaft 1, which is convenient for installing the positioning plate 312. A square groove 311 is provided on the outer wall of the circular groove 310, so that the T-block 37 will not hinder the insertion during insertion. The outer wall of the circular groove 310 is fixedly installed with a positioning plate 312, which can make the positioning plate 312 stuck in the groove of the T-block 37 to fix the rotating shaft.

[0024] Specifically, the shielding mechanism 4 includes: a threaded hole 41, a protective cover 42, a convex groove 43, and a bolt 44. The inner wall of the circular groove 310 is provided with a threaded hole 41, which is convenient for the bolt 44 to be screwed in. The bottom of the No. 1 rotating shaft 1 is fitted with a protective cover 42, which can protect the bottom and does not hinder normal work. The outer wall of the protective cover 42 is provided with a convex groove 43, which is convenient for the bolt 44 to be screwed into the threaded hole 41. The inner wall of the convex groove 43 is fitted with a bolt 44, so that the bolt 44 can pass through and fit in the convex groove 43. The button 36, the T-block 37, and the bolt 44 are provided in two groups, and are symmetrical with the central symmetry axis of the front side of the No. 1 rotating shaft 1, and are symmetrically distributed at the front and rear ends of the No. 1 rotating shaft 1, which can make the docking more secure and facilitate the installation of the protective cover 42. The outer wall of the bolt 44 is connected to the inner wall of the threaded hole 41 with a thread, so that the bolt 44 can be screwed into the threaded hole 41.

[0025] Working principle: In order to facilitate the installation and disassembly of the shaft, the top of the second shaft 2 is inserted into the bottom of the first shaft 1, so that the hexagonal block 32 on the second shaft 2 is inserted into the hexagonal groove 39 of the first shaft 1 to prevent the shaft from rotating after docking, and then slide off the side of the T-block 37 through the square groove 311, so that the positioning plate 312 squeezes the T-block 37, so that the T-block 37 moves toward the center of the second shaft 2, and at the same time drives the spring 38 to stretch. In the circular groove 310, the positioning plate 312 is stuck in the groove of the T-block 37, and the spring 38 resets to enable the T-block 37 to tightly clamp the positioning plate 312, so that the second shaft 2 is stuck at the bottom of the first shaft 1. When disassembling, only two fingers are needed to press the two buttons 36 to make the buttons 36 slide at the passing position. The limiting groove 35 is to limit the depth of the button 36 to prevent the button 36 from falling off, and then pull out another shaft. This makes installation and disassembly convenient and improves work efficiency.

[0026] When the shaft does not need to be docked, the bolt 44 can be screwed into the threaded hole 41 to fix the protective cover 42 on the bottom of the shaft, and the bolt 44 will be screwed into the convex groove 43 to prevent it from protruding and hindering processing and use. The protective cover 42 covers the bottom of the shaft to prevent damage during processing and use, and can be the same size as the outer wall of the shaft, so that the shaft can work normally after installation.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
