Description

Technical Field

[0001] This utility model relates to the field of joint structure technology, specifically a puppet joint structure. Background Technology

[0002] Rotatable dolls provide excellent models for enthusiasts to understand human anatomy. However, existing doll mechanisms often require large areas of exposed joints to increase flexion and extension angles between limbs. Furthermore, to accommodate maximum flexion and extension, recessed grooves are often added to the limbs near the joint structures. These large exposed joint areas and recessed grooves negatively impact the overall aesthetics of the doll. Therefore, there is a conflict between the flexion and extension angles of the doll's limbs and the aesthetic appeal of exposed joints. There is an urgent need for a human doll that can satisfy the requirements of limb flexion and extension while minimizing exposed joints and preserving the overall integrity of the limbs. To address this, this invention provides a doll joint structure. Utility Model Content
