The invention discloses a screw tightening device for a printer, and the invention relates to the technical field of screw tightening, comprising a picking frame, wherein the inner wall of the picking frame is fixedly connected with a working cylinder, the outer wall of the working cylinder is provided with a limiting groove, the inner wall of the working cylinder is slidably connected with a telescopic column, and by arranging the working cylinder and the clamping plate, the movement of the tightening head drives the telescopic column to overcome the elastic force of the working spring and slide along the limiting groove of the outer wall of the working cylinder, the sliding of the telescopic column drives three groups of connecting rods on the outer wall of the lifting block to move synchronously, and then the movement of the connecting rod drives the clamping plate to slide along the outer wall of the picking frame and fit with the side wall of the working screw, and at the same time, the sliding of the telescopic column drives the rotating pillar and the positioning support groove to abut against each other, so as to realize the positioning operation after the clamping plate and the working screw are fitted, so as to avoid the working screw from being offset during the picking process, and the working screw is not accurately positioned, resulting in damage to the installation part of the printer body.

The utility model belongs to the technical field of saggers, and particularly relates to a wear-resistant sagger which comprises a sagger body, a stacking ring groove is formed in the edge of the bottom end of the sagger body, an isolation disc is fixedly connected to the edge of the top end of the sagger body, a stacking block is fixedly connected to the top end of the isolation disc, and a connecting groove is formed in the bottom end of the isolation disc. The sagger comprises a sagger main body, a connecting groove is formed in the sagger main body, a connecting ring is fixedly connected to the connecting part of the sagger main body and the connecting groove, reinforcing ribs are arranged in the sagger main body, and a worker installs the isolation disc on the sagger main body through the arrangement of the isolation disc and is embedded into the connecting ring at the top end of the sagger main body through the connecting groove in the bottom end of the isolation disc; stable installation operation of the isolation disc is achieved, a worker places the sagger bodies on the isolation disc, stacking operation of the multiple sagger bodies is achieved by embedding the stacking ring grooves in the bottom ends of the sagger bodies and the stacking blocks at the top ends of the isolation disc, the multiple sagger bodies are isolated by arranging the isolation disc, and the abrasion resistance of the sagger bodies is improved.

The utility model discloses a PCB connector insulating casing forming die, specifically related to forming die technical field, including lower forming die, collection box and two injection tubes, and the collection box slides in one side of lower forming die, and the top of collection box is equipped with two injection tubes, and two injection tubes all are fixedly connected with lower forming die between intercommunication, the lower surface of collection box is equipped with collection limiting component, collection limiting component includes the slider fixed setting in the lower surface of collection box, and the outer wall slidingly connected of slider has the slide frame, the utility model discloses through collection limiting component, and the sleeve joint block drives the left shift of limiting block, and the collection box realizes the guiding sliding along the upper surface of slide frame, and the slider is limited on the collection box, and the injection liquid of injection tube overflow trickles and flows down to the inside of collection box, and along collection box enters inside and collects, can realize the collection operation to the overflow injection liquid, and the collection effect is better.
