Preferably, the multi-joint structure comprises a plurality of spheres and a plurality of sleeves, and the spheres and the sleeves are arranged at intervals and movably connected together. The ball is spaced from the sleeve, which is preferably conical, with spaces at both ends to accommodate portions of the ball, such as a bowl. Preferably, the diameter of the sleeve is gradually reduced from the base to the chuck part, the diameter of the ball is gradually reduced from the base to the chuck part, and the overall external dimension of the multi-joint structure is gradually reduced from the base to the chuck part.
Preferably, the articulated structure further comprises a cable on which the ball is connected in series with the sleeve. A through hole is arranged between the ball body and the sleeve and is used for passing through the cable. The diameter of the through hole is related to the adjustment range of the multi-joint structure, and the diameter of the setting hole is preferably 2-3 times of the diameter of the cable, and is not suitable to be too large. The balance between locking and the rotation amplitude in each direction needs to be comprehensively considered. Preferably, the through hole structure of the sphere can also be a through hole with gradually changed aperture, and if the opening is slightly larger and the aperture of the middle part of the through hole is slightly smaller, the sleeve can also adopt the through hole with gradually changed aperture. Therefore, the rotation amplitude of the joint structure in all directions can be increased, and the joint structure is easy to lock in a bending state.
