the pipe clamping jaw, the pipe clamping jaw includes close or the first left and right pipe clamp finger that removes the setting from each other, be provided with relative first, second pipe contact pin respectively on the first left and right pipe clamp finger and be used for passing respectively the slide breach and insert and be located in the core hole of the terminal plastics pipe of first, second pipe slide, the pipe clamping jaw is put plastics pipe clamp on the pipe locating surface.

8. The automatic assembly device of a hinge according to claim 4, characterized in that: still include four hole feed mechanism and arm body feed mechanism, conveyer conveying the carrier passes through earlier four hole feed mechanism with arm body feed mechanism passes through again the second nail machine of wearing, four hole feed mechanism include:

the torsional springs are arranged in the torsional spring slide ways in a sliding manner;

the four-hole piece slideway is arranged in the four-hole piece slideway in a sliding manner, and a concave position formed between two side walls of the four-hole piece is towards the torsion spring slideway;

the assembling chute is arranged between the tail end of the four-hole piece slideway and the tail end of the torsion spring slideway and is used for allowing a torsion spring to slide through;

the pushing block is telescopically arranged on one side of the tail end of the torsion spring slide way, when pushed out, the pushing block pushes the torsion spring at the tail end of the torsion spring slide way to slide through the assembling sliding groove and enter the four-hole piece at the tail end of the four-hole piece slide way, and at the moment, the torsion spring is aligned with the connecting holes of the four-hole piece;

four hole material loading clamping jaws, four hole material loading clamping jaws include close or four hole spare clamp fingers on the first left and right that the removal set up that leaves mutually, be provided with the both ends that relative four hole spare contact pins of first, second are used for inserting the connecting hole of torsional spring and four hole spare on the four hole spare clamp fingers on the first left and right respectively, four hole spare clamping jaws are put four hole spare and torsional spring synchronous clamp on the carrier.

9. The automatic assembly device of a hinge according to claim 8, characterized in that: the carrier top surface in the torsional spring locating surface with downwardly extending's torsional spring location breach has between the arm body locating surface, the torsional spring is placed the both ends orientation of torsional spring when on the torsional spring locating surface the arm body locating surface just is located torsional spring location breach top, arm body feed mechanism includes:

the torsion spring guiding device comprises a guide pin and a guide pin driving mechanism for driving the guide pin to stretch and descend, the guide pin is arranged on one side of the carrier, the stretching direction of the guide pin faces the torsion spring positioning gap, the guide pin driving mechanism drives the guide pin to extend out, so that the guide pin is inserted into the bottom of the torsion spring positioning gap, and when the guide pin driving mechanism drives the guide pin to ascend, the guide pin ascends along the torsion spring positioning gap, so that the end part of the torsion spring which is hooked by the guide pin ascends is upward;

arm body clamping jaw, the arm body clamping jaw is including being used for the centre gripping the arm body of arm body presss from both sides the finger, set up in the arm body presss from both sides the briquetting that indicates one side and is used for the drive the arm body presss from both sides the arm body clamping jaw actuating mechanism who indicates, briquetting synchronous movement, arm body clamping jaw actuating mechanism drive the arm body press from both sides the finger centre gripping arm body in when arm body locating surface top descends, the right-hand member portion swing decline that the right-hand member portion that the briquetting contacted the torsional spring earlier made the torsional spring keeps being located the below of arm body.
