wherein, 1-clamping part, 2-hinge part, 21-perforation, 3-connecting handle, 4-meshing part, 41-convex tooth structure, 5-finger ring, 10-first clamp rod and 20-second clamp rod.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in figures 1 to 3 of the drawings,

a handkerchief clamp injection molding blank comprises a first clamp rod 10 and a second clamp rod 20, wherein the first clamp rod 10 and the second clamp rod 20 are respectively provided with a clamping part 1, a hinge part 2 and a holding part which are correspondingly matched, a right angle or an obtuse angle is formed between a clamping end of the clamping part 1 and a connecting rod, and the clamping end is connected with the connecting rod through a smooth curved surface; the cooperation of contained angle between exposed core and the connecting rod makes its centre gripping handkerchief, can avoid the exposed core to pierce perpendicularly the handkerchief, damages the handkerchief, and then can ensure to wrap the injury of time skin, wound at the wound.

As shown in fig. 2, the hinge portion 2 of the first lever 10 is a structure with a through hole 21 on a side surface, the through hole 21 is used for the clamping portion 1 of the second lever 20 to pass through, and the hinge portion 2 of the second lever 20 is movably hinged between the through holes 21 of the hinge portion 2 of the first lever 10, through the arrangement of the through hole 21, the two hinge portions 2 can form a sandwich-type hinge fit, so that the matching effect of the two levers is enhanced, and meanwhile, the through hole 21 effectively limits the movement of the second lever 20, so that the unfolding and closing angles of the handkerchief clamp are limited, and the handkerchief clamp can be prevented from being damaged by excessive closing of the first lever 10 and the second lever 20 when the handkerchief is clamped.
