Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The structure of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the embodiment of the utility model provides a rotatable scraper suitable for medical orthopedics, including first disc 1, the fixed second disc 2 that is provided with in upper end of first disc 1, first disc 1 and the fixed threaded rod 3 that is provided with of second disc 2 central authorities department run through, the fixed hexagonal spiral shell head 4 that is provided with of lower extreme of threaded rod 3, the outer wall threaded connection that the second disc 2 was extended to the upper end of threaded rod 3 has hexagon nut 5, all fixed stripe tooth 7 that is provided with intermeshing between first disc 1 and the second disc 2, the fixed grab handle 8 that is provided with of right-hand member of first disc 1, the fixed connecting plate 10 that is provided with in left end of second disc 2, the left end joint of connecting plate 10 has blade 11, the fixed three fixing bolt 12 that is provided with between blade 11 and the connecting plate 10.

Referring to fig. 1 and 2, a hexagonal groove 6 corresponding to the hexagonal screw head 4 is formed in the center of the lower end of the first disk 1, and the hexagonal screw head 4 is clamped in the hexagonal groove 6.

Adopt above-mentioned scheme: through setting up hexagonal groove 6, can be so that 6 joint hexagonal spiral heads 4 in hexagonal groove for the staff is by the joint at 3 lower extremes of threaded rod when revolving wrong hexagon nut 5, and unable oneself rotates, makes things convenient for the staff to loosen soon, screws, avoids when revolving wrong hexagon nut 5, and idle running of lower extreme threaded rod 3 and hexagonal spiral heads 4.

Referring to fig. 1 and 2, a protection plate 9 is fixedly arranged at the upper end of the handle 8, and the rear end and the right side of the protection plate 9 are fixedly connected with the upper end of the handle 8.
