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.

The utility model provides a novel sharp instrument protective sleeve as shown in figures 1-3, which comprises a fixed ball 1 and a fixed plate 2, wherein one end of the fixed ball 1 is an open end, the open end of the fixed ball 1 is provided with the fixed plate 2, and two sides of the fixed plate 2 are provided with a limiting structure; the limiting structure comprises a chute 3, a slide block 4, a first spring 5, a connecting rod 6, a driving block 7, a through groove 8, a second spring 9, a fixed rod 10 and a rotating wheel 11, a sliding groove 3 is arranged on the side wall surface of the fixed plate 2, sliding blocks 4 are arranged on two sides of the sliding groove 3, a first spring 5 is arranged between one end of the sliding block 4 and the side wall surface of the sliding chute 3, one end of the connecting rod 6 is movably connected with the other end of the sliding block 4, the driving block 7 is movably connected with the other end of the connecting rod 6, a through groove 8 is arranged on one side of the driving block 7 far away from the connecting rod 6, a second spring 9 is arranged in the through groove 8, a fixed rod 10 is arranged on the second spring 9, the fixed rod 10 is positioned in the through groove 8, the rotating wheel 11 is arranged on the fixed rod 10, and the rotating wheel 11 is positioned on one side of the driving block 7, which is far away from the connecting rod 6; an elastic sealing layer 12 is arranged on the opening end of the fixing ball 1; the top of the fixed plate 2 is provided with a handle 13; the fixing rod 10 is concave.
