The movable end of the third driving member 501 is inserted between the third bending body A503 and the third bending body B504 and is used to drive the third bending body A503 and the third bending body B504 to rotate about the hinge point. The provision of the third extrusion portion A505 and the third extrusion portion B506 makes the structural layout reasonable and prevents the third bending member 502 from affecting other unrelated needle bodies 1.

[0042] In some embodiments of the present application, Figure 4 、 7 As shown, a shaft is installed on the bottom plate, and the middle part of the third bending body A503 and the third bending body B504 are both provided with a sleeve and are rotated on the shaft through the sleeve.
