Automatic send nail system

The utility model provides an automatic send nail system includes: it constructs to join in marriage the nailing machine for deposit the screw, it constructs to go out the nailing machine for supply the screw to stretch out to treating binding work piece department, transport mechanism connects and constructs and go out between the nailing machine structure in joining in marriage the nailing machine for construct the conveying to going out the nailing machine structure with the screw from joining in marriage the nailing machine, wherein, join in marriage the nail establishment of institution in go out the top that the nailing machine constructs, so that the screw is when the transport mechanism internal motion, the direction of the gravity that the screw receives with the contained angle of the direction of motion of screw is the acute angle all the time. From this, can make the screw can be under the effect of gravity slide along transport mechanism and construct to going out the nailing machine, smooth and
