Equal length its extended line be mutually perpendicular to.Side after two fixed frame plate make-ups is hinged with mutual corresponding movable slats, living
The top and bottom of movable plate item are respectively corresponded equipped with activity adjustment screw hole, are connected with tune between corresponding activity adjustment screw hole
Save screw rod, the middle part of adjusting screw rod is equipped with polygon adjustable column, the left-handed screw and right handed screw at adjusting screw rod both ends respectively with
The left hand thread and right-handed thread of activity adjustment screw hole are threadedly coupled.The other side of one of fixed frame plate is fixed with and fixes
The security strip that frame plate is connected as one, the top and bottom of security strip are respectively equipped with secured adjusted screw hole, secured adjusted spiral shell
Adjusting rod is threaded in hole, the other end of adjusting rod is equipped with the adjusting nut with secured adjusted screw hole derotation, adjusting nut
Outer surface be equipped with polygon adjustable column.Stay hook is threaded in adjusting nut, stay hook and corresponding fixed frame plate are another
The fixation hook groove of side connects.It has been movably connected with fixed backing plate in the inner surface of fixed frame plate straight section, it is fixed
The outer surface of backing plate is equipped with elastic protective layer.
Adjusting screw rod or adjusting rod surprisingly fall off during work or transport in order to prevent, can also adjust as needed
The both ends of screw rod or one end of adjusting rod are equipped with Anti-releasing nut.
Stronger stabilization more labor-saving when adjustable column in order to adjust both sides in operation, fixed, can also match
There is the adjusting spanner to match with polygon adjustable column.
The raw material such as existing aluminium alloy, plastics, plank, foamed plastics and universal machine zero can be selected in the utility model
Part, and using conventional technique processing and fabricating, it is easy to implement.
The utility model is designed reasonably, structure are simple, at low cost, operation is convenient, fixed speed is fast, fixation, safety
Reliably, it is easy to promote the use of, have a wide range of application, there is practical and popularizing value.

Specific embodiment
The utility model is further described with the embodiment provided with reference to the accompanying drawing.
Referring to attached drawing, this long bone knitting fixator is made of, fixed frame the fixed frame plate 1 of two bar shapeds of mutual make-up
The cross-sectional shape of plate is in straight a, arc b, straight c three parts, its extended line of the equal length of both sides straight section mutually hangs down
Directly.Side after two fixed frame plate make-ups is hinged with mutual corresponding movable slats 2, and the top and bottom of movable slats are right respectively
It should be equipped with activity adjustment screw hole 3, be connected with adjusting screw rod 4, the middle part of adjusting screw rod between corresponding activity adjustment screw hole
Equipped with regular hexagon adjustable column 4.1, the left-handed screw 4.2 and right handed screw 4.3 at adjusting screw rod both ends respectively with activity adjustment spiral shell
The left hand thread and right-handed thread in hole are threadedly coupled.The other side of one of fixed frame plate is fixedly connected with to be connected with fixed frame plate
It is connected in integrated security strip 1.2, the top and bottom of security strip are respectively equipped with secured adjusted screw hole 6, secured adjusted screw hole
In be threaded with adjusting rod 7, the other end of adjusting rod is equipped with the adjusting nut 7.1 with secured adjusted screw hole derotation, adjusts spiral shell
