Furthermore, the open face is configured on the end face included by the raw ear through end part and extends along the periphery of the raw ear through part to form an expansion part, and the clamping points are distributed on the expansion part and are clamped with the upper end of the hand shifting head.

Furthermore, the expansion part is arranged on the half circumference of the outer wall of the raw ear tube.

Furthermore, notches are arranged on two sides of the expansion part.

Further, the clamping point is arranged on the expansion part and adjacent to the opening on the end face.

Furthermore, the wall thickness of the raw ear tube is between 0.15mm and 0.30 mm.

Further, the elastic member is a spring.

Furthermore, the side of the clamping point connected with the edge of the end part with the opening surface is an inclined surface.

The utility model has the beneficial effects that:

the utility model comprises an integrally formed hand-pulling head, wherein an opening with a clamping point is arranged at the end part of the raw ear tube, the hand-pulling head is arranged in the raw ear tube through an opening surface, and the hand-pulling head is limited in the raw ear tube by matching with the clamping point, so that the installation is simple and easy, and the practicability is strong.

Detailed Description

Referring to fig. 3-6, the present invention relates to a hand-pulling ear-growing structure, which comprises a raw ear tube 1, an elastic member 2, and a raw ear head 3, wherein the elastic member 2 and the raw ear head 3 are both disposed in the raw ear tube 1,

still include integrated into one piece's hand and dial head 4, give birth to the open face that the edge took stuck point 8 that disposes of the tip of ear expert 1, and hand is dialled head 4 and is located in giving birth to ear expert 1 and offset with stuck point 8 through opening the face.

The raw earpieces 1 are made of metal.

Furthermore, the open surface is configured on the end surface included by the end part of the raw ear tube 1 and extends locally along the periphery of the raw ear tube 1 to form an expansion part 5, and the clamping points 8 are distributed on the expansion part 5 and are clamped with the upper end of the hand poking head 4; the upper end of the hand-pulling head 4 is a push rod for pushing the appliance, and the expansion part 5 is the moving stroke of the push rod and pushes the push rod to compress the elastic part 2.

Furthermore, the expansion part 5 is arranged on the half circumference of the outer wall of the raw ear tube 1; with the above arrangement, it is intended to provide a suitable width for the plectrum head 4 to pass through, and by limiting the width of the expanding portion 5, the cost can be greatly reduced.

Furthermore, notches 6 are formed in two sides of the expansion part 5, and the notches 6 are designed to meet the requirement of forming a clamping point 8, specifically, the clamping point 8 is arranged on the expansion part 5 and is adjacent to an opening in an end face, and the clamping point 8 and two sides of the expansion part 5 are integrally formed, so that the two sides of the expansion part 5 are divided into two parts through the existence of the notches 6, the expansion part 5 adjacent to the end face of the raw ear tube 1 is bent to form the clamping point 8 through the snapping of an external force, before the assembly, the expansion part 5 is positioned on the same horizontal plane and cannot prevent the hand shifting head 4 from entering the raw ear tube 1, and after the installation of each part is completed, the expansion part 5 is bent to form the clamping point 8, so that the hand shifting head 4 cannot be separated from the raw ear tube 1; it should be noted that, the elastic resilience of the peripheral elastic sheet at the notch 6 of the raw ear tube 1 can be increased by the notch 6.

Furthermore, the wall thickness of the raw otoxin 1 is between 0.15mm and 0.30 mm; the thickness of the material is less than the above size, which can affect the poor elasticity of the raw otoxin 1 and the hand dialing head 4 during the assembling process.

Further, the elastic member 2 is a spring; the spring is a universal part, the structure is simple and easy, and the practicability is strong.

Furthermore, the side of the clamping point 8 connected with the edge of the end part with the open surface is an inclined surface 7; the bevel 7 is designed to project the click 8 with a bevel by which the handspike 4 can be guided quickly into the raw otonic canal 1.

The above embodiments are merely illustrative of the preferred embodiments of the present invention, and not restrictive, and various changes and modifications to the technical solutions of the present invention may be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are intended to fall within the scope of the present invention defined by the appended claims.
