Detailed description of the invention
In description of the present utility model, it is to be understood that term " radially ", " axially ", " on ", D score, " top ",
Orientation or the position relationship of the instruction such as " end ", " interior ", " outward " they are based on orientation shown in the drawings or position relationship, merely to just
Describe in description this utility model and simplification rather than indicate or imply that the device of indication or element must have specific side
Position, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.In description of the present utility model
In, except as otherwise noted, " multiple " are meant that two or more.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", should be interpreted broadly " setting ", " connection ", for example, it may be fix connection, it is also possible to be to removably connect, or integratedly
Connect；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary.For the ordinary skill in the art,
Above-mentioned term concrete meaning in this utility model can be understood as the case may be.
As Figure 1-3, the fixing board component that merges of the rear ankle of the present embodiment includes merging plate and bone screw, merges plate
There is straight fixed plate 11 and oblique fixed plate 12, straight fixed plate 11 and oblique fixed plate 12 with rear ankle in laminating shape, in order to just
Merge plate and the laminating of rear ankle in adjusting fusion plate preferably to allow, use adjustable between oblique fixed plate 12 and straight fixed plate 11
Structure, specifically, straight fixed plate 11 has cavity near one end of oblique fixed plate 12, and oblique fixed plate 12 is near straight fixed plate
One end of 11 has convergence part 121, and convergence part 121 is plugged in cavity, and the both sides of convergence part 121 are provided with ratchet 122, in cavity
It is provided with the elastic shank coordinated with ratchet 122, straight fixed plate 11 can be allowed to stretch or receive by adjusting the position of convergence part 121
Contracting.When lifting straight fixed plate 11, resilient key body elasticity deforms, and so ratchet 122 near elastic shank moves up and gets over
Cross elastic shank, at least provided with two groups of position phases in then elastic shank reset of card lives ratchet 122, the cavity in the present embodiment admittedly
