Free slant platform

A free slant platform comprising:

• a ball structure with a rotator structure comprising a stopping hole formed on a side thereof;
• a loading plate located above the ball structure and fixedly connected with the ball structure;
• a supporting member slidably connected with an outer wall of the ball structure and configured to support the ball structure;
• a stop member movably connected with the supporting member and linearly moved along an axis direction of the ball structure to clamp with the stopping hole for braking the ball structure;
• and wherein
• when the stop member presses on the ball structure, the stop member is clamped with the stopping hole to limit rotation of the ball structure;
• when the stop member is separated from the ball structure, the ball structure is restored to a free rotation state thereof;
• and wherein
• the stop member comprises a guiding portion with a circular arc rotator structure, a plurality of stop pins and an elastic layer formed on an outer wall of the guiding portion, a plurality of guiding holes passing through a body of the guiding portion, one end of the stop pin passing through the guiding hole to compress the elastic layer, and the other end of the stop pin extending out of the guiding hole;
• and wherein when the stop member presses on the ball structure, some of the plurality of stop pins abut against the outer wall of the ball structure and then move along the guiding hole to press on the elastic layer tightly, and some of the plurality of stop pins are inserted into the stopping hole to clamp with edges of the stopping holes so as to limit rotation of the ball structure.
