Specific implementation mode
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific implementation mode, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all are created using the utility model of the utility model design in the row of protection.
According to one embodiment of the application, with reference to figure 1, the track switch of this programme spreads a group clamping rail device special of changing planes, including
Structure is identical and symmetrically arranged two clamp assemblies, two clamp assemblies are fixedly linked by multiple connecting rods 7, Duo Gelian
A U-type groove is formed between extension bar 7 and two clamp assemblies.
With reference to figure 1- Fig. 3, two clamp assemblies include handle 1, upper fastener 2 and lower fastener 3.Upper fastener 2 and connector 4
Between offer it is several for accommodating the through-holes of connecting rod 7, and the arc-shaped shape in the top of upper fastener 2 and connector 4, arc shape
Inside be used to accommodate the top of rail 6, therefore the inside length of arc shape need to be more than the width at 6 top of rail.Connecting rod 7 is passed through
Connector 4 and upper fastener 2 are fixedly linked by through-hole.
One end of lower fastener 3 is L-shaped, and the other end is semicircle, the bottom of upper fastener 2 and connector 4 respectively with lower fastener 3
The two sides of semi-circular ends are flexibly connected, which is pin joint.
1 one end of handle is movably connected on the top of upper fastener 2, that is, is movably arranged at the connection at 2 top of connector 4 and upper fastener
On bar 7, the other end adjusts one end pin joint of lead screw 5, adjusts 5 other end of lead screw and is movably connected on 3 semi-circular ends of lower fastener
Two sides.
