Rotatable anti-slip device and all-terrain anti-slip sole

A rotatable anti-slip device, comprising a device main body (1), characterized in that the device main body (1) comprises a mounting seat (11) and an anti-slip mechanism (12) rotatably connected to the mounting seat (11), wherein the anti-slip mechanism (12) comprises a friction part (121) and a rotation part (122) connected to the friction part (121), wherein the rotation part (122) comprises a sphere (123) and a rotating shaft (124) connected between the sphere (123) and the friction part (121), wherein the friction part (121) comprises a first friction surface (125) and a second friction surface (126) facing opposite to the first friction surface (125), and the friction part (121) comprises anti-slip components (127) arranged on the second friction surface (126);

• the mounting seat (11) comprises a sliding groove part (111) that cooperates with the sphere (123), an upper part of the sliding groove part (111) is configured to be a cylindrical structure, and a lower part is configured to be a spherical structure, wherein the sliding groove part (111) has a first opening (112) for the sphere (123) to enter and exit, and a second opening (113) for avoiding the rotating shaft (124) and the second opening (113) is configured to limit the position of the sphere (123);
• the mounting seat (11) also comprises an avoiding arc surface (114) for avoiding the friction part (121).
