Toothbrush
The design features an elongated body with one end characterized by a flat base. Extending outward from this base are a number of fiber bundles generally perpendicular to the base. Following the longitudinal axis, the base narrows to form a neck and gradually widens to form a handle. The handle tapers towards the other end, culminating in a sharp point with a through hole. Protection is not sought for the text containing the expression "+x+" as it appears within the body of the design. 1.1) Left side view; 1.2) Top view; 1.3) Bottom view; 1.4) Front view; 1.5) Rear view; 1.6) Front-left side view

A skeleton shell shaping mechanism
This utility model relates to the field of skeleton assembly, and more particularly to a skeleton shell shaping mechanism. The clamping mechanism includes multiple shaping blocks that converge toward the center point. These shaping blocks, through convergence, form a shaping platform that applies uniform pressure to the outside of the positioning teeth. The inner top mechanism includes an inner top block and a lower pressure plate surrounding the inner top block. The inner top block passes through the shell on the lower pressure plate and compresses the positioning teeth that intersect with the movement path of the inner top block. It also forms a positioning mechanism that fixes the shell during shaping by constraining the positioning teeth with the shaping platform. First, the positioning teeth of the annular structure of the shell are shaped internally and externally. Through the cooperation of the clamping mechanism and the inner top mechanism, a structural repair effect is achieved. Second, since the positioning teeth have sharp points, the clamping mechanism is chosen to avoid contact with the sharp points and apply pressure from the side of the sharp points, thus avoiding the problem of secondary bending of the sharp points.
