The invention relates to a composite guide rail of vehicle door glass. The composite guide rail comprises a guide rail body for accommodating the edge of vehicle door glass and a sealing strip which is connected with the guide rail body and guides and keeps the vehicle door glass in the middle position of the guide rail body; and the composite guide rail also comprises a bonding layer which is positioned in the connecting part between the sealing strip and the guide rail body and connects the sealing strip and the guide rail body into a whole. The invention also discloses a method for manufacturing the guide rail. The composite guide rail of the vehicle door glass and the method for manufacture the same are implemented and have the following advantages: as the bonding layer is positioned in the connecting part between the guide rail body and the sealing strip, the guide rail body and the sealing strip are combined into a whole; the shearing stress is larger; therefore, the sealing strip is uneasy to fall off from the guide rail body; and the vehicle door glass is also uneasy to insert into the part between the guide rail body and the sealing strip.

The invention discloses a tool bit of a pen-shaped eyebrow shaping tool. The tool bit comprises a columnar tool bit body, a blade is arranged on the tool bit body, the tool bit and a handle can form the eyebrow shaping tool of a pen-shaped structure, the blade is of a bent arc-shaped structure, and a cutting edge at the upper end of the blade corresponds to an arc shape. Therefore, on the premisethat the safety is ensured, compared with an existing straight eyebrow shaping blade, the blade can be very small and is not prone to being inserted into flesh; the upper end of the blade is arrangedon the upper end face of the tool bit body, the tool bit can move perpendicular to the skin or move by inclining by a certain angle in the direction perpendicular to the skin during dehairing, an inclined cutting angle is formed by obliquely arranging the blade relative to the axis L of the tool bit body, the cutting sharpness is guaranteed, eyebrows can be effectively cut off by holding the pen-shaped eyebrow shaping tool to operate like a pen, eyebrow shaping flexibility and controllability are improved, the blade of the arc-shaped structure can effectively control scraping and planing of concave-convex parts, and therefore eyebrow shaping and molding can be accurately achieved.

The invention discloses a novel pin shaft fixing bolt. The novel pin shaft fixing bolt comprises a free part (11), a closing part (12) and a spring part (13), wherein the free part (11) is inserted into a pin shaft (2); the closing part (12) is used for preventing the bolt (1) from dropping out of the pin shaft (2); the spring part (13) is used for providing elasticity for the bolt (1); the middle part of the bolt (1) is bent to form the spring part (13); the two ends of the bolt (1) are positioned at the same side of the spring part (13) after being bent, wherein one end is bent inwards to form the closing part (12), and the other end acts as the free part (11). The novel pin shaft fixing bolt disclosed by the invention is normally closed in both a working state and a nonworking state, is automatically closed after being inserted into a pin shaft hole and does not cause drop of the bolt due to human negligence; even when the bolt is scraped by an external force, the opening of the bolt can also be automatically closed after the external force disappears as long as a needle pin is not pulled out, so the pin shaft hardly falls off; an inward angle is formed after the closing part has contact with the free part, so the pin shaft can be inserted quite easily and also hardly drops out.

The invention discloses a cold-rolling strip steel threading method, which belongs to the field of strip steel rolling. The cold-rolling strip steel threading method comprises the steps of (1) being in no hurry to pull a strip tail over a rolling mill after the rolling of a previous strip steel is completed and the strip tail is separated from a jaw; (2) carrying out feeding operation of a next strip steel by an uncoiling worker, and feeding the head part of the next strip steel to the outer side of an inlet oil scraper roller of the rolling mill; (3) enabling the uncoiler running speed V (uncoiling) to be equal to the rolling mill running speed V (rolling mill) after the tail part of the previous strip steel and the head part of the next strip steel are in up-and-down lap joint; (4) stopping the feeding by the uncoiling worker when the head part of the next strip steel reaches to the position of an outlet guide roller of the rolling mill by successfully penetrating through the rolling mill along with the tail part of the previous strip steel; and (5) coiling the tail part of the previous strip steel, and coiling the tail part of the previous strip steel to a steel coil. According to the cold-rolling strip steel threading method disclosed by the invention, a cold-rolling strip steel is prevented from being firstly inserted in a roller seam clearance between a working roller of the rolling mill and an intermediate roller or under an oil spray guide plate during a twenty-high rolling mill threading process, and successful threading operation is realized.
