The outer wall of first swivel nut and the second swivel nut is provided with external screw thread.
Further, screw hole is provided with first swivel nut, forcing screw is installed in the screw hole.
Further, universal ball is provided with second swivel nut, pressurization multi-directional ball is provided with the universal ball
Or locking multi-directional ball.
The beneficial effects of the invention are as follows：Locked pressurized bone plate provided by the invention, pressurization spiral shell can be applied as needed
Nail, the requirement when setting for multi-directional ball of pressurizeing can meet to pressurize to angle, when locking can be met by locking the setting of multi-directional ball
Requirement to angle.The present invention is easy to process, it is only necessary to five screwed holes are processed on bone plate body, it is overlapping to avoid processing
Pressurization hole and complexity during locking hole.

Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings.
As shown in figure 3, bone plate body 1 is the metallic plate of strip, five spaced sets are provided with bone plate body
Mounting hole 11, mounting hole is screwed hole.Screw thread is provided with the first swivel nut 2 in the screwed hole positioned at centre, such as Fig. 8, Fig. 9 institute
Show, the first swivel nut 2 is circular metalwork, is provided with screw hole 21 at the center of the first swivel nut, is set on the outer wall of the first swivel nut
There is external screw thread 5, forcing screw 41 is installed in screw hole.The second swivel nut is provided with the mounting hole positioned at high order end and low order end
3, as shown in Figure 6, Figure 7, the second swivel nut is circular metalwork, and universal ball 31, multi-directional ball are provided with the center of the second swivel nut
Hole inner wall smooth is used to install pressure multi-directional ball 6, and the outer wall of the second swivel nut is provided with external screw thread 5, to facilitate the second swivel nut and peace
Fill the connection in hole.As shown in figure 4, the upper and lower end face of pressure multi-directional ball 6 is parallel, and the side of pressure multi-directional ball is spherical, and
First through hole 61 is provided with pressure multi-directional ball, forcing screw 41 is installed in first through hole.Per two adjacent pressurization spiral shells
Also screw thread is provided with the second swivel nut 3 in mounting hole between nail, locking multi-directional ball 7 is provided with second swivel nut, such as Fig. 5 institutes
Show, lock that the upper and lower end face of multi-directional ball is parallel, the side for locking multi-directional ball is spherical.The is provided with the center of locking multi-directional ball
Two through holes 71, are provided with lock-screw 42 in the second through hole.
As shown in Figure 1, Figure 2, shown in Figure 10, five mounting holes are provided with so on bone plate body, in the mounting hole of centre
Provided with the first swivel nut, forcing screw is installed in the first swivel nut.The second swivel nut is provided with remaining four mounting hole, at both ends
The second swivel nut in pressure multi-directional ball is installed, forcing screw is installed in pressure multi-directional ball.Two the second swivel nuts in centre
In locking multi-directional ball is installed, lock-screw is installed in multi-directional ball is locked.
When vertical angles are pressurizeed, the first swivel nut, the first swivel nut are screwed into the mounting hole among bone plate body
On first through hole on there is no internal thread, be then directly threaded into forcing screw.Pay attention to, at forcing screw and bone plate body contacts
It is not to use threaded connection, is used only to pressurization and is not intended to fix.
When the limitation due to skeletal structure needs that forcing screw is angled to be screwed into, this just needs to apply universal nodule
Structure device, the device be the second swivel nut and the second swivel nut being screwed into by two from bone plate body mounting hole wrapped up plus
Multi-directional ball composition is pressed, pressurization multi-directional ball can be rotated freely in the second swivel nut, so as to ensure the demand of different angle, pressurization
