Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a bolt convenient to change lead screw, which comprises a bolt body, be equipped with the silk pole 1 on the bolt body, silk pole 1 includes preceding pole 11, back pole 12, connecting axle 13 and spacer pin 14, connecting hole 121 has been seted up at the top of back pole 12, the one end of connecting axle 13 runs through the top of preceding pole 11 and stretches into in the connecting hole 121, connecting axle 13 closes the connection with connecting hole 121 soon, the 14 activities of spacer pin set up at the top of connecting axle 13 and use with the top cooperation of preceding pole 11, connecting axle 13 is fixed on back pole 12 through spacer pin 14 with preceding pole 11, loosen connecting axle 13 soon, it can take off preceding pole 11 and change to demolish spacer pin 14, then it can to reset spacer pin 14 and connecting axle 13.
Specifically, as shown in fig. 1, a fitting hole 111 is formed through the top of the front rod 11, and the connecting shaft 13 is in transition fit with the fitting hole 111, so that the front rod 11 and the rear rod 12 are coaxially distributed to form a complete screw post 1.
