Detailed Description

As shown in fig. 1-2, the utility model provides a technical solution: the utility model provides a nail ware of getting is used in operation, including an installation section of

thick bamboo

1, 1 bottom fixed surface of an installation section of thick bamboo installs well cavity frame 9, well cavity frame 9 side both ends are inside all to run through movable mounting has movable rod 10, every movable rod 10 inboard middle-end surface all fixedly cup joints fixed sleeve 11, every fixed sleeve 11 top surface all articulates through the pivot has catch bar 8, the vertical fixed mounting in 1 inboard middle-end of an installation section of thick bamboo has

dead lever

2, 2 middle-end surface activities of dead lever have cup jointed

transmission sleeve

3, 3 side both ends of transmission sleeve all articulate through the pivot have connecting rod 5, the vertical fixed mounting in 3 bottom side both ends of transmission sleeve has installation pole 6, the inside both ends of 1 side of an installation section of thick bamboo all articulate through the pivot has transmission clamp plate 4, and 5 sides of connecting rod articulate mutually in 4 inboard of transmission clamp plate through the pivot, and 6 inboard tops of installation pole articulate in 3 side both ends surfaces of transmission sleeve through the pivot, 2 bottom surface activities of dead lever have cup jointed

lifting sleeve

7, and 8 tops articulate in lifting sleeve 7 side both ends through the pivot.

In the technical scheme, two ends of the side of the connecting rod 5 are respectively connected with the transmission pressing plate 4 and the transmission sleeve 3 through the rotating shaft, so that when an operator holds the surface of the installation barrel 1 with one hand, the transmission sleeve 3 and the lifting sleeve 7 can be driven to synchronously move in the vertical lifting mode on the surface of the fixing rod 2 under the transmission of the connecting rod 5 only by pressing the outer side of the transmission pressing plate 4 through the muscle on the inner wall of the palm of one hand, and further corresponding inward pulling power is provided for the fixing sleeve 11 through the transmission effect of the push rod 8, so that the movable rods 10 can synchronously and oppositely move inside the hollow frame 9, the tops of bone nails placed inside the hollow frame 9 are clamped, the abutting limiting processing of the bone nails is completed, the operator can conveniently perform pulling processing and subsequent instrument taking auxiliary operation on the bone nails with one hand, and the subsequent pulling efficiency is improved.

In some solutions (as shown in fig. 1 and 2), a clamping block 13 is fixedly mounted on one end surface of each movable rod 10 near the fixed sleeve 11.

In the technical scheme, the stability of the whole device during the extraction of the bone nail is ensured by the clamping limiting treatment of the clamping block 13.
