The thickness of the sleeve body is 1-5 mm.

Adopt the utility model has the advantages of:

1. the utility model discloses a key improvement lies in adopting solitary thread bush and solitary connection body combination to form combined type connecting piece, compares with the connecting piece of current screw thread and connection body formula structure as an organic whole, both makes whole connecting piece can keep higher intensity, can improve the corrosion resistance of connecting the body again, more is favorable to being applied to in the trade of various corrosive environment. In addition, the connecting pieces are required to have high strength, so that the strength of materials is high, and the diameter of the connecting body can be reduced by adopting a combined structure, so that the aim of reducing the processing cost is fulfilled. The utility model discloses improve present conventional integral type connecting piece for integrated configuration, not only overcome the technology bias, still gained unexpected technological effect.

2. The utility model discloses a interference fit's mode will overlap the body assembly on connecting the body, is favorable to improving the cover body and is connected the steadiness between the body.

3. The utility model discloses in connect the body when being the structure including nail pole, head of a nail and nail point, with establish the screw cover body cooperation, can form combination formula screw, penetrate connecting pieces such as nail. When the connecting body is of a structure comprising a rod body and a cap body, the connecting body is matched with the sleeve body with threads, so that a bolt connecting piece can be formed. So that the whole connector can be applied to different industries.

4. The utility model discloses when adopting the ail shooter percussion with the connecting piece, remaining energy when being favorable to the buffering shooting through the buffer segment.

5. The utility model discloses establish the thickness of the cover body to 1-5 mm, be favorable to the screw thread on the cover body to follow and connect the body and get into the base member smoothly.

Detailed Description

The utility model discloses a combined connecting piece, including connecting body 1 and the cover body 2, be provided with screw thread 3 on the

cover body

2, 2 fixed cover of the cover body are established on connecting body 1. Preferably, the sleeve body 2 is assembled on the connecting body 1 in an interference fit manner.

The utility model discloses in, the thickness of the cover body 2 is 1-5 mm, preferably 2.5mm or 4mm, and specific thickness can set up according to different trade needs. The connecting body 1 and the sleeve body 2 can be made of the same or different materials, and particularly, when the connecting body and the sleeve body are used in a corrosive environment, the sleeve body 2 can be made of a corrosion-resistant material, or a corrosion-resistant coating layer can be arranged on the sleeve body 2. When the connecting body 1 is actually used, the sleeve body 2 can play a role in corrosion resistance, and the connecting body 1 is prevented from being corroded, so that the corrosion resistance of the connecting piece can be improved on the premise that the connecting piece has higher strength.

The utility model discloses according to actual need, both can all set up screw thread 3 on the cover body 2, also the spaced type sets up screw thread 3. Further, the number of the sleeve bodies 2 on the connecting body 1 can be one or more.
