Casing is fixedly connected, and another is fixedly connected with first sleeve and passes through the sliding slot across the second casing, and two locking arms can
Using using connecting shaft as axis rotation, the maximum angle being able to rotate is the radian of sliding slot；The locking arm is in arc-shaped, described
Locking bar shares two, is connected by a hinge respectively two locking arm ends, and two locking bars, which are equipped with, mutually fits matching
Teeth, the locking bar end is equipped with connecting rod, is maximized when surgical and received according to the width of patient's fracture site bone
Tight locking arm and locking bar, can lock locking bar using teeth makes it be unlikely to unclamp, and makes two locking bar relative position quilts
Fixed, the connecting rod, which can be used for pulling locking bar outward, separates teeth, and the fixed strip is equipped with fixing groove, fixed groove width
Vertical interval is coincide between degree and two connecting rod outer diameters, and fixed strip is placed into connecting rod, so that connecting rod is embedded in fixing groove, then
Connecting rod, which is limited to fixed groove width, at this time to drive locking bar to be displaced outwardly again, therefore two locking bars are fixed, device
Locking degree no longer changes；There are two the clamping limb is set, connected for directly contact clamping fracture site, clamping limb by bearing
Knob is connect, the knob is threadedly coupled with locking arm, and bearing can suitably adjust the angle between locking arm and clamping limb as needed
Degree, can also guarantee that clamping limb will not be driven rotation when further being adjusted using knob.
Further, second casing is externally provided with the first torque spring, two toggles difference of the first torque spring
Two locking arms are connected, so that two locking arms is generated the trend of Natural closure, so that locking operation is simpler.
Further, the locking arm and locking bar connecting portion are equipped with the second torque spring, and two toggles connect respectively
Locking arm and locking bar are connect, two locking bars can be made to generate the trend that nature comes closer, be intermeshed teeth, so that lock
It tightly operates simpler.
Beneficial effect possessed by the utility model is: the structure design of the utility model is reasonable, and two locking arms can be with
Connecting shaft is axis rotation, so as to closed and locked device；Using the occlusion between locking bar teeth so that two locking bars are with respect to position
It sets and is fixed, vertical interval is coincide between fixed groove width and two connecting rod outer diameters, and connecting rod can be made to be limited to fixed groove width
Locking bar cannot be driven to be displaced outwardly again, therefore two locking bars are fixed, device locking degree no longer changes；Locking arm and folder
Angle between gripping arm is adjustable, interferes surgical operation to prevent locking apparatus, and in addition clamping limb also can use knob progress
Further adjust.

Specific embodiment
1 ~ 5 pair of the utility model is described below with reference to the accompanying drawing.
As shown in Fig. 1 ~ 5, the utility model includes connection component, locking arm 6, locking bar 9, fixed strip 11 and clamping limb
14, the connection component includes first sleeve 3, the second casing 4, connecting shaft 1 and connection shaft seat 2, and the connecting shaft 1 is located at connection
The top of axle bed 2, and with 2 integrally connected of connection shaft seat, connection shaft seat 2 is to support first sleeve 3 and the second casing 4, the company
Spindle seat 2 is equipped with grip fixed handle 5, to gripping device, or utilizes bolt that grip fixed handle 5 is fixed, surgical procedure
In without helping, the first sleeve 3 is nested in the outside of connecting shaft 1, and second casing 4 is nested in 3 outside of first sleeve, institute
It states 4 side of the second casing and is transversely provided with sliding slot 4-1, the locking arm 6 shares two, and one is fixedly connected with the second casing 4, separately
One is fixedly connected with first sleeve 3 and passes through the second casing 4 by the sliding slot 4-1, and two locking arms 6 can be with connecting shaft
1 is axis rotation, and the maximum angle being able to rotate is the radian of sliding slot 4-1；The locking arm 6 is in arc-shaped, the locking
Item 9 shares two, is connected to two 6 ends of locking arm by hinge 7 respectively, and two locking bars 9, which are equipped with, mutually fits matching
Teeth 9-1,9 end of locking bar is equipped with connecting rod 10, when surgical most according to the width of patient's fracture site bone
Bigization tightens locking arm 6 and locking bar 9, and can lock locking bar 9 using teeth 9-1 makes it be unlikely to unclamp, and makes two lockings
9 relative position of item is fixed, and the connecting rod 10, which can be used for pulling locking bar 9 outward, separates teeth 9-1, the fixed strip
11 are equipped with fixing groove 11-1, and vertical interval is coincide between fixing groove 11-1 width and two 10 outer diameters of connecting rod, and fixed strip 11 is put
It sets in connecting rod 10, so that connecting rod 10 is embedded in fixing groove 11-1, then connecting rod 10 is limited to fixing groove 11-1 width not at this time
Locking bar 9 can be driven to be displaced outwardly again, therefore two locking bars 9 are fixed, device locking degree no longer changes；The clamping limb
14 set there are two, for directly contact clamping fracture site, clamping limb 14 connects knob 12 by bearing 13, the knob 12 and
Locking arm 6 is threadedly coupled, and bearing 13 can suitably adjust the angle between locking arm 6 and clamping limb 14 as needed, can also be
Guarantee that clamping limb 14 will not be driven rotation when further being adjusted using knob 12.
Further, second casing 4 is externally provided with the first torque spring 15, two toggles of the first torque spring 15
Two locking arms 6 are separately connected, so that two locking arms 6 is generated the trend of Natural closure, so that locking operation is simpler.
Further, the locking arm 6 is equipped with the second torque spring 8, two toggle difference with 9 connecting portion of locking bar
Locking arm 6 and locking bar 9 are connected, two locking bars 9 can be made to generate the trend that nature comes closer, nibble teeth 9-1 mutually
It closes, so that locking operation is simpler.
When using the device, two locking arms 6 are separated, reset portion need to be clamped by being located at clamping limb 14, be pulled outward
Connecting rod 10 simultaneously inwardly tightens locking bar 9, and connecting rod 10 is unclamped after to be tightened is intermeshed teeth 9-1 in two locking bars 9,
Simultaneously by 11 sets of fixed strip in connecting rod 10, the width for enabling connecting rod 10 be limited to fixing groove 11-1 cannot drive locking bar again
9 are displaced outwardly, screw at this time knob 12 further clamp fracture site and by bearing 13 adjust locking arm 6, locking bar 9 and
