Both pass through screw hole and a pushing block is fixedly mounted, the one side of pushing block towards clamping plate is pasted provided with a rubber layer, and the rubber
Glue-line offsets with corresponding clamping plate；One second screw rod is fixedly mounted by articulated elements in the upper end of left side claw beam, right side claw beam
Upper end is provided with a through hole, and second screw rod one end extends to the external world through through hole, and is threadedly coupled a nut, the left surface of nut with
Right side claw beam offsets.
Preferably, the rounded structure setting of the pushing block, and the diameter of pushing block is identical with the width of binding clip.
Preferably, the clamping plate is made up of 304 steel, and ridge is uniformly laid with the medial surface of clamping plate.
Preferably, the length of the clamping plate is less than the length of binding clip, and binding clip is located at the lower section headspace of bearing pin.
Preferably, the handle is provided with anti-skidding overcoat.
Preferably, the quarter of distance between the binding clip of corresponding two arcuate structures is evenly arranged with the outer wall of second screw rod
Degree.
Preferably, the medial surface of the rubber layer is pasted (i.e. close to clamping plate side) provided with a SMD pressure sensor,
Big dipper module is set in the SMD pressure sensor；The big dipper module is realized by way of short message communication with mobile terminal
Data interaction.
The invention has the advantages that：The present invention is simple in construction, easy to use, can increase with the perfect clamping of bone
Add the contact surface with bone, avoided slippage, and jaw need not be unclamped and just fixed in carrying out, avoid second fracture.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the embodiment of the present invention；
Fig. 2 is the left view of the embodiment of the present invention.
Embodiment
In order that objects and advantages of the present invention are more clearly understood, the present invention is carried out with reference to embodiments further
Describe in detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this hair
It is bright.
As depicted in figs. 1 and 2, the embodiments of the invention provide a kind of new orthopaedic trauma replacement and fixation being accurately positioned
Clamp, including two are located at bearing pin lower end and are respectively formed an arcuate structure by the symmetrical hinged claw beam 5 of bearing pin, claw beam 5
Binding clip 1, a fix bar 10 is fixedly mounted on the medial surface of binding clip 1, an arc is fixedly mounted on the end face of fix bar 10
The clamping plate 6 of structure, two screw holes are equipped with each binding clip 1, one first screw rod 8 is threadedly coupled in two screw holes,
The one end of first screw rod 8 may be contained within the external world, and one handle 2 is fixedly mounted, and the other end both passes through screw hole and is fixedly mounted one and pushes away
Block 9, towards a rubber layer is fixedly mounted on the one side of clamping plate 6, rubber layer offsets pushing block 9 with clamping plate 6, left side pincers
One second screw rod 4 is fixedly mounted by articulated elements in the upper end of bar 5, and the upper end of right side claw beam 5 is provided with a through hole, the second screw rod 4 one
End extends to the external world through through hole, and is threadedly coupled a nut 3, and left surface and the right side claw beam 5 of nut 3 offset, and pass through nut
Claw beam can be effectively clamped, jaw is firmly clamped, doctor is saved doctor without applying inside clamping force to claw beam
Strength.
In the present embodiment, the rounded structure setting of pushing block 9, the diameter of pushing block 9 is identical with the width of binding clip 1, avoids
Pushing block is exposed at the external world.
In the present embodiment, clamping plate 6 is made up of 304 steel, clamping plate is had certain deformability, clamping plate 6
Ridge 7 is equipped with medial surface.
