Form an overfill. In order to further improve the reliability of the scalp assembly installation, along the entire circumference of the scalp body 2, the interference of the outer edge of the rim 201a is greater than the interference of the inner rim.

As can be seen from FIG. 17 to FIG. 19, the headstock assembly B is combined with the head cover assembly A. A contact strip 11 is provided with a convex second positioning pin 111. The head cover assembly A is provided with a concave positioning groove 121 on the second contact strip 12 coupled with the headstock assembly B. The positioning slot 121 is covered by the positioning slot 121. When the headrest assembly B and the head cover assembly A are locked, the second positioning pin 111 is inserted into the positioning slot 121. In the conventional smooth contact belt locking mode, it is difficult to maintain a completely balanced locking state of the joint portion of the head cover assembly A and the headstock assembly B regardless of the design of the locking device, particularly the portion having a sudden recess in the joint portion. It is difficult to lock the concave portion, and the inventors have conducted many years of experiments and improvements on this problem, but have not achieved the desired effects. Therefore, in the present invention, a locking structure locking device is designed at the joint portion of the head cover assembly A and the headstock assembly B. In the locked state, the second positioning pin of the device is engaged with the flexible locking edge 201. In the groove 121, the seam is prevented from coming out under the condition of pulling, and the normal use of the head mold is ensured.

 The first contact strip 11 is provided with at least three second positioning pins 111, and the second contact strips 12 are provided with the same positioning slots 121 as the second positioning pins 111, and each of the second contacts The positioning pins 111 are all formed in a cylindrical shape, a triangular tooth shape or a polygonal cylindrical shape, and the shape of each of the positioning grooves 121 is adapted to the shape of the corresponding second positioning pin, and the top end of each of the second positioning pins 111 is a circle. In an arc shape, the second positioning pins 111 are continuously arranged along the first contact belt 11 to form a continuous tooth shape. The top end of the second positioning pin of the present invention adopts a surface of a circular arc to prevent damage to the locking edge during locking.

As can be seen from FIG. 2 and FIG. 3, the cross-section of the rim 201 is slotted, and the scalp assembly A1 is connected to one side of the slot wall. The edge of the head cover assembly A is embedded in the slot, and the first contact of the header assembly B is The end surface of the belt 11 is groove-shaped, and the bottom surface of the locking edge 201 is convex. The bottom surface of the locking edge 201 and the groove bottom surface of the first contact strip 11 are in an un-locked state of the headstock assembly B and the head cover assembly A. There is a gap between the bottom surface of the locking edge 201 and the first contact strip 11 The gap between the bottom surfaces of the trough is preferably 1 to 3 mm. In the present invention, the end surface of the first contact strip 11 is designed as a groove shape 112, and the bottom surface of the locking edge 201 is designed as a convex shape 205, which is advantageous for the locking edge to be embedded in the first contact strip 11 as much as possible, due to the locking engagement of the locking edge. In the groove of the belt, when the head shell assembly presses the seam, the pressure on the groove wall attachment is relatively large, and the seam is not easily pulled out. In the case of pressing the bottom of the groove, the groove wall will be retracted to further lock the seam. The gap between the locking edge 201 and the first contact strip 11 is such that during the locking process, the head shell assembly squeezes the locking edge into the groove of the first contact strip 11 as much as possible, thereby improving the headstock assembly. The locking force between the B and the head cover assembly A also ensures that the locking of the scalp assembly does not come out. The present invention can effectively prevent the locking edge from coming out by the above multiple locking measures, thereby ensuring the normal use of the head mold.
