2) The arm drives the bending transfer mechanism to move to the assembling station, in the moving process, the bending driving piece 31 drives the lifting pressing block 32 to slide downwards, the far ends 332 of the two clamping jaws 33 are pressed downwards, then the two ends of the handrail are driven to swing downwards, the handrail is bent by a certain angle, then the pin holes of the handrail can be aligned with the pin holes of the hinge 200, and pin penetrating operation can be carried out through the lower computer.

3) After the pin is inserted, the bending driving member 31 drives the lifting press block 32 to slide upwards, the pressure of the lifting press block 32 on the far ends 332 of the two clamping jaws 33 disappears, and the far ends 332 of the two clamping jaws 33 swing upwards to reset under the action of the pulling force of the elastic resetting member 34. Then, the steps can be repeated to clamp the next handrail and carry out the pin penetrating operation.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model.
