in order to achieve the purpose, the utility model provides a multi-angle stoppable rotary limiting handle shaft, which comprises a shaft cover, a casing wall and a handle, wherein a clamping block is clamped in a mounting hole on the handle, a spring gasket is arranged inside the clamping block, a bulge matched with a clamping groove at the inner side of the clamping block is arranged at the outer side of the spring gasket, and the clamping grooves are arranged in a plurality of uniform and equidistant positions;

The shaft cover sequentially penetrates through the handle, the clamping block and the spring gasket and is connected with a tightening screw penetrating through the shell wall;

The clamping block is attached to the shell wall, and the shell wall is attached to the handle.

Preferably, the end part of the shaft cover is provided with symmetrical notches, the length of each notch is greater than the thickness of each spring gasket, and each spring gasket is provided with a through hole matched with the corresponding notch.

Preferably, the number of the protrusions is two, and the two protrusions are symmetrically arranged and are in a cone-shaped structure.

Preferably, the exposed part of the clamping block is arranged to be of a cylindrical structure, the part of the clamping block clamped in the handle is arranged to be of a square structure, and a hole in the clamping block is arranged to be circular and is adapted to the circular part of the shaft cover.

Preferably, the mounting hole is arranged in a square structure and is adapted to the clamping block.

Therefore, the utility model adopts the above structure the rotatory spacing handle axle of multi-angle stoppable has compressed the overall dimension of spacing axle, makes the casing process more easily, and the structure is compacter, through adjustment shell fragment structure, makes it have dual spacing effect under the effect of pretension power, has guaranteed that the handle can stop in the different angles that need.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
