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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-8, the present invention provides a technical solution: the utility model provides a novel combination screw, as shown in fig. 4, connecting hole 2 has been seted up to the side on fixed block 1, and connecting hole 2 is inside to have seted up cross recess 3, through the setting of connecting hole 2 for when wearing and tearing appear in cross recess 3, let stop block 5 enter into connecting hole 2 inside and drive this novel combination screw and rotate, cause this novel combination screw to use and be difficult to receive the influence.

As shown in fig. 1, fig. 2, fig. 3, fig. 5 and fig. 6, connecting hole 2 is inside to be provided with fixed plate 4, and fixed plate 4 sets up at 1 upside of fixed block, the diameter of fixed plate 4 is greater than the internal diameter of connecting hole 2, make outside dust be difficult to enter into inside connecting hole 2, it sets up at fixed plate 4 downside to shelter from piece 5, and it sets up inside connecting hole 2 to shelter from piece 5, the shape that shelters from piece 5 is the same with the shape of connecting hole 2, the diameter that shelters from piece 5 simultaneously equals the internal diameter of connecting hole 2, make and shelter from behind piece 5 entering into connecting hole 2 inside, can drive this novel combination screw and rotate, the side is provided with commentaries on classics.

As shown in fig. 2, the lead screw 7 is disposed on the lower side of the fixing block 1, the first external thread member 8 is disposed on the outer side of the lead screw 7, and the hollow cylinder 9 is disposed on the outer side of the lead screw 7, the diameter of the hollow cylinder 9 is greater than that of the lead screw 7, so that the hollow cylinder 9 is conveniently mounted on the lead screw 7.

As shown in fig. 1, fig. 7 and fig. 8, the side is provided with stopper 10 on the hollow cylinder 9, hollow cylinder 9 is threaded connection through between internal thread 11 and the lead screw 7, be connected through the first external screw thread spare 8 on internal thread 11 and the lead screw 7, cause hollow cylinder 9 to conveniently be connected with lead screw 7, and hollow cylinder 9 sets up at 1 downside of fixed block, the diameter of stopper 10 equals the diameter of fixed block 1, effect through stopper 10, make hollow cylinder 9 easy to assemble spacing, hollow cylinder 9 medial surface is provided with internal thread 11, hollow cylinder 9 lateral surface is provided with second external screw thread spare 12 simultaneously.
