The cylindrical shape is convenient to process, and accords with mechanical basis, and the setting up of built-in groove makes the anastomosis member can stably place, prevents the radial extension of pressurized.

In the automobile bolt based on the inosculating structure, the orthographic projection of the head part falls into the top end of the positioning part.

Namely, the center of the head part is matched with the axis of the positioning part.

In the automobile bolt based on the inosculating structure, the inosculating surface is arc-shaped.

In practice, the radian of the fit surface is various and can be selected and matched according to the shape of the actual surface.

In the automobile bolt based on the anastomosis structure, a flared transition part is further arranged between the positioning part and the head part, and the transition part is flared from the head part to the positioning part.

The transition portion plays the transition effect, and the transition portion can increase the circumferential torsion resistance of bolt.

In the automobile bolt based on the inosculating structure, the head part, the transition part, the positioning part and the screw rod are integrally formed.

In the automobile bolt based on the inosculating structure, the head part is hexagonal prism-shaped.

In the automobile bolt based on the inosculating structure, the screw rod, the head part and the transition part are all made of carbon alloy steel.

Compared with the prior art, the automobile bolt based on the inosculation structure has the following advantages:

1. this automobile bolt based on structure that coincide passes through the design of the identical piece of detachable, makes the bolt can adapt to the connected face of the connected thing of various different shapes, makes and laminates more between face and the face, forms effective laminating, and reinforcing stability is to the connected face of the connected thing of difference, removable different identical piece.

2. This automobile bolt based on coincide structure pastes the face change into dismantling removable structure with pasting of current bolt, design benefit, and the practicality is strong.

3. This automobile bolt based on coincide structure makes the coincide piece can stably place through seting up of built-in groove, prevents that the pressurized is radial to be extended.
