[0028] The working principle of the utility model is that the worm wheel 232 is in a self-locking state when the worm 232 is locked, so that when the rotating shaft 23 is not rotating, the angle between the handle 2 and the connecting rod 3 and the plate body 1 will not change;
[0029] When the angle between the handle 2 and the plate body 1 needs to be adjusted, the rotating shaft 23 is driven to rotate by the toggle block 231, and the rotating shaft 23 can drive the worm 232 to rotate when rotating. Since the worm wheel 232 is rotatably connected to the handle 2 through the pin shaft 13, the worm 232 will rotate along the worm wheel 232 when rotating, thereby driving the handle 2 to rotate around the pin shaft 13 as the axis, so that the angle between the handle 2 and the connecting rod 3 changes. Since the connecting rod 3 is always in a vertical state with the plate body 1 through the connecting block 31 and the locking bolt 17, the angle between the plate body 1 and the handle 2 changes. The user can adjust the angle according to his or her own needs when holding it, without having to keep the arm in a greatly bent state for a long time, which can effectively avoid arm soreness and discomfort for the user.
