The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses protector of external stone crusher.

Referring to fig. 1 and 2, the protection device of the extracorporeal lithotripter comprises a fixed frame 1 and a protection plate 2, wherein the fixed frame 1 and the protection plate 2 are both in a circular plate shape integrally, and the fixed frame 1 and the protection plate 2 are arranged coaxially. The fixed frame 1 is provided with a window hole 11, and the cross section of the window hole 11 is oval.

Referring to fig. 2, be provided with baffle 12 on fixed frame 1, baffle 12 is whole for the ring form, and baffle 12 and fixed frame 1 coaxial setting, the one end and the fixed frame 1 integrated into one piece of baffle 12 axis direction, and the other end extends to guard plate 2 one side, and guard plate 2's lateral wall is contradicted with baffle 12. So that the stability of the rotation of the shielding plate 2 is improved.

Referring to fig. 2, through holes 21 are formed in the protection plate 2, the cross section of each through hole 21 is circular, four through holes 21 are uniformly arranged around the axis direction of the fixed frame 1 at intervals, the four through holes 21 are sequentially reduced along the clockwise direction, the protection plate 2 is rotated along the axis direction of the fixed frame 1, and the through holes 21 can be communicated with the window holes 11. So that the applicability of the guard is improved.

Referring to fig. 2, a rotating shaft 13 is disposed on the fixed frame 1, the rotating shaft 13 is disposed coaxially with the fixed frame 1, one end of the rotating shaft 13 is integrally formed with the fixed frame 1, and the other end of the rotating shaft passes through the protection plate 2. The rotating shaft 13 penetrates through one end of the protection plate 2 to be provided with a pressing plate 14 in a penetrating mode, the whole pressing plate 14 is in a circular plate shape, and the pressing plate 14 and the rotating shaft 13 are arranged coaxially.
