the torsional 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 notch, the guide pin driving mechanism drives the guide pin to extend out, so that the guide pin is inserted into the bottom of the notch, and when the guide pin driving mechanism drives the guide pin to lift, the guide pin lifts along the notch, so that the end part of the torsional spring hooked by the guide pin is upward;

the arm body clamping jaw is used for clamping the arm body and placing the arm body on the arm body positioning surface.

Preferably, the arm body clamping jaw is including being used for the centre gripping the arm body of arm body presss from both sides indicates, 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 motion, arm body clamping jaw actuating mechanism drive the arm body press from both sides indicate the centre gripping arm body in when arm body locating surface top descends, a tip that the briquetting contacted the torsional spring earlier makes a tip swing decline of torsional spring keep being located the below of arm body.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the end part of the torsion spring faces the arm body and is positioned above the notch by arranging the torsion spring positioning surface, so that the guide is arranged to extend into the notch and the end part of the ascending and descending torsion spring is uniformly corrected to be upward, and one end of the torsion spring can be pressed below the arm body when the arm body is pressed downwards;

through set up the briquetting on the arm body clamping jaw and be used for pressing the tip of moving the torsional spring earlier than the arm body, ensure that the one end of torsional spring keeps in arm body below, when having avoided the arm body to press and move torsional spring tip and descend, unevenness department on the arm body probably interferes with the torsional spring tip, makes arm body material loading more stable.
