Face；The groove-like structure that detent slot is one 135 °, the mutual inlay card of detent block with 45 ° in self-supporting component enclosure in self-supporting component,
So that the rotation angle of support frame is limited between 90 ° of horizontal and vertical angles；Central spindle spring groove is in spring in self-supporting component
The card slot of end bending block.
10. a kind of knee replacements bracket according to claim 1, it is characterized in that: the self-supporting component packet
Include self-supporting component enclosure, detent block, spring, snap ring, snap ring supporting shell, supporting shell spring groove；Self-supporting component enclosure is a side
Shape hollow shell structure, is placed in base groove；Snap ring supporting shell is also a rectangular hollow shell structure, is placed in self-supporting component enclosure,
There are supporting shell spring grooves for lower part；Detent block is the part extended in self-supporting component enclosure into shell, is 45 ° of arcs for an inner arc
The mutual inlay card of detent slot in the string configuration of shape, inner arc and self-supporting component central spindle, so that the rotation angle of support frame limits
System is between 90 ° of horizontal and vertical angles；Spring is that internal diameter is small, and the big flat bar metal spring of outer diameter, there is bending in interior outer end
Block, inner end bend the mutual inlay card of central spindle spring groove in block and self-supporting component central spindle, and outer end bends block and supporting shell spring groove phase
Mutual inlay card；Snap ring is placed in the annular groove in self-supporting component central spindle, under the action of snap ring supporting shell, stops self-supporting component central spindle
Fall off.
