The cone pendulum movement can be performed along the Z-axis direction, wherein, since the handle 40 will drive the movement of the second limiting member 60 during the swinging process, the fulcrum of the cone pendulum movement will also change correspondingly in three-dimensional space.

When the external force acts on the operating portion 41 of the handle 40 along the X-axis direction, since the fixing portion 45 of the handle 40 is fixedly connected to the first limiting member 50 , the swing fulcrum (located on the side of the fixing portion 45 facing the rod portion 43 ) is located at the operating portion 41 of the handle 40 . Between the part 41 and the fixing part 45, the first limiting member 50 is movably clamped in the first opening 1332 and the second opening 1372, the first limiting member 50 swings in the opposite direction to the X-axis, and at the same time The elastic member 70 is deformed; when the external force is lost, the elastic member 70 restores the deformation, and the first limiting member 50 restores to the initial position under the action of the elastic member 70 and drives the handle 40 to restore to the initial position at the same time.

The first opening 1332 and the second opening 1372 are in an inverted U-shape with a large lower end opening. The first clamping portion 53 has space for movement along the Y-axis. Swing in the opposite direction to the Y-axis, so that the handle 40 drives the first limiting member 50 to move along the Y-axis direction, the handle 40 can also swing along the Y-axis direction, and the movement of the first limiting member 50 drives the elastic member 70 to deform; When the external force is lost, the elastic member 70 restores its deformation, and the first limiting member 50 restores to the initial position under the action of the elastic member 70 and drives the handle 40 to restore to the initial position at the same time. Wherein, during the deformation process of the elastic member 70 , the second limiting member 60 is also driven to be displaced.

When the external force acts on the operation part 41 of the handle 40 in any direction perpendicular to the Z-axis direction and in any direction except the X-axis direction and the Y-axis direction, since the fixed part 45 of the handle 40 is fixedly connected to the first limiting member 50, the first A limiter 50 and the handle 40, the pivot point is located between the operation part 41 and the fixed part 45, the first limiter 50 moves in the opposite direction of the action direction, the first limiter 50 and the first opening 1332, the second The opening 1372 and the first gap 535 cooperate with each other, so that the first limiting member 50 has a movable space in the XY plane, so the handle 40 can swing in the action direction. When the external force is lost, the elastic member 70 restores its deformation, and the first limiting member 50 restores to the initial position under the action of the elastic member 70 and drives the handle 40 to restore to the initial position at the same time. Wherein, during the deformation process of the elastic member 70 , the second limiting member 60 is also driven to be displaced.

To sum up, the interaction of the first limiting member 50 , the second limiting member 60 , the housing 10 and the elastic member 70 enables the handle 40 to perform a 360° cone pendulum motion with the Z-axis direction as the axis.

It can be understood that, in some embodiments, when the extending direction of the first limiting member 50 and the extending direction of the second limiting member 60 are at other angles, the first limiting member 50 and the second limiting member 60 cooperate with each other. The directions of the first opening 1332 , the third opening 1352 , the second opening 1372 and the fourth opening 1392 on the housing 10 can also be adjusted accordingly.
