[0002] The elbow is a commonly used connecting pipe fitting in plumbing installation. It is used for connecting at the bend of the pipe to change the direction of the pipe. Other names include: 90° elbow, right-angle elbow, stamped elbow, pressed elbow, machine elbow, welded elbow, etc.

[0003] For example, a special machine for double-station tapping of elbow pipe fittings with application publication number "CN106735623A" realizes automatic loading and double-station tapping of elbow pipe fittings to be processed, and the work efficiency of tapping elbow pipe fittings is increased by 320%. It also optimizes the tapping equipment for elbow pipe fittings and reduces the investment in tapping equipment for elbow pipe fittings. However, when the double-station tapping machine for elbow pipe fittings performs double-station tapping on elbow pipe fittings, the equipment directly uses two cylinders to work when limiting the elbow pipe fittings. Since the operation of the cylinder is extremely unstable and the speed fluctuates greatly, the cylinder will be deformed in the subsequent operation, affecting the subsequent limiting work. At the same time, when the double-station tapping machine for elbow pipe fittings performs double-station tapping, the double-station tapping position of the equipment is fixed, and the tapping position cannot be adjusted, so the work of the equipment has limitations.
