The rotating sleeves 301 are sleeved outside the universal ball heads 201 and can rotate around the universal ball heads 201 .

[0032] Specifically, combined Figure 4As shown, the universal ball head includes a connecting body 2012 fixed on the support part 2 and a ball head body 2011 fixed to one end of the connecting body 2012 away from the support part 2, the connecting body 2012 is detachably connected to the support part 2, the connecting body 2012 is perpendicular to the end surface of the support part 2 and parallel to the horizontal plane, the ball head body 2011 is detachably connected to the connecting body 2012, the rotating sleeve 301 is sleeved outside the ball head body 2011, the rotating sleeve 301 has a retaining edge that can prevent it from falling off the ball head body 2011, and the end surface of the chest support part 3 close to the support part 2 is provided with an embedding groove for the rotating sleeve 301 to be embedded.
