Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
A kind of internal fixation of spine cross-connecting apparatus as shown in Figure 1, Figure 2 and Figure 3, including connecting plate 1 and set up separately
Fixed chuck 2 in both ends, two center symmetric settings of fixed chuck 2 and to be respectively arranged with a bayonet socket in its bottom opposite
Claw 21, the middle part of the connecting plate 1 is provided with a rotating shaft 3 that can freely rotate perpendicular to plate face, the rotating shaft 3 it is upper
Portion is fixedly connected with a gear 4, and the upper surface both sides of connecting plate 1 are respectively symmetrically provided with a chute 11, the fixed chuck 2
Top is respectively arranged with a transfer arm 22 that can be moved left and right along chute 11, and the medial surface of the transfer arm 22 is provided with can
The rack engaged with gear 4.
Wherein, the chute 11 and the junction of transfer arm 22 are L-shaped, and it can cause fixed chuck 2 with connecting plate 1 not
It can occur to come off up and down；The top of the rotating shaft 3 is provided with adjustment hole 31；The middle part of the connecting plate 1 is provided with one and is communicated to
The longitudinal section of the side of rotating shaft 3 is the through hole 13 of horizontal T-shaped, and a push rod 5, the through hole are provided with the transverse holes of the through hole 13
