Specific embodiment
In order to be better understood from the present invention, illustrate with reference to the accompanying drawings and examples.
Embodiment：As Figure 1-3, teleconverter of the present invention includes microscope group 1, extension ring 2 and trim ring 3.The side of microscope group 1
Wall is provided with two fix bars 11, and the screwed hole 21 for fixing trim ring 2 is provided with the top end face of extension ring 2,
Fig. 4, Fig. 5 show the structure of trim ring of the present invention, and as shown in Figure 4, Figure 5, the inner ring of trim ring 3 is provided with installation fix bar
11 guide slide 31, the entrance 311 of the guide slide is located at trim ring upper surface, from entrance 311 to trim ring inside extend and formed
Chute surface 312, the end of chute surface 312 is provided with draw-in groove 313, and the upper surface of draw-in groove 313 is slightly above chute surface 312.The edge of trim ring 3 is set
There is contact notch part 32, the upper surface of trim ring 3 is provided with least two grooves 33, and bottom portion of groove is provided with screw hole 34, the groove 33
Bore is provided with elastomer 4 slightly larger than the diameter of screw cap in groove 33, and the upper end of elastomer 4 is resisted against screw cap bottom, under
End is resisted against bottom portion of groove.As shown in Fig. 2 screw 5 is through the groove 33 on trim ring 3 and the elastomer 4 in groove, by screw
It is screwed into behind hole 34 in the screw hole 21 of extension ring 2, is fixed on extension ring 2.
As Fig. 3 shows that microscope group is installed on stereogram when on extension ring, during installation, fix bar 11 is put in trim ring 3 and is led
To being rotated along chute surface 312 after in chute inlet 311, being down depressed into bottom, now chute surface 312 and the upper surface of extension ring 2
The spatial altitude of formation is less than the height of fix bar 11, and trim ring 3 is moved up in the presence of fix bar 11, and elastomer 4 is pressurized
Enclose the pressure of the bottom surface of groove 33 and screw cap and shrink, because the bore of groove 33 is more than screw cap, screw cap is absorbed in groove 33
It is interior.It is rotated further in fix bar 11 to draw-in groove 313, elastomer 4 gives the bottom surface of trim ring groove 33 downward pressure, the part of trim ring 3
Move down and be fixed bar 11, the position of fix bar 11 is fixed under the pressure of trim ring 3 and the backstop of draw-in groove 33.Now, by the increment
Mirror is connected between camera body and camera lens the effect for being capable of achieving extension focal length, and microscope group is tightly fastened under trim ring, during shooting
Will not be moved, so as to ensure shooting effect.When needing microshot, backwards rotation microscope group is only needed, removed.This
Invent the teleconverter and realize two kinds of functions of microspur/increment, and it is convenient to disassembly.
As a modification of the present invention, as shown in fig. 7, guide slide 31 is set to the L for diametrically stretching out
Type slideway, guide slide entrance 311 is U-shaped, and because trim ring thickness is smaller, this shape is easy to process.
For more preferable fixed microscope group, microscope group 1 is provided with two symmetrical fix bars 11, is uniformly provided with trim ring 3
Four cylinder shape grooves 33.
The elastomer 4 can be spring, be sleeved on the screw 5；Can also be elastic caoutchouc, be filled in trim ring recessed
In groove 33.
The material of trim ring 3 is metal, can be stainless steel or aluminium alloy, and the trim ring intensity of metal material is good, service life
It is long.
The above, is only presently preferred embodiments of the present invention, is not the limitation for making other forms to the present invention, is appointed
What those skilled in the art changed possibly also with the technology contents of the disclosure above or be modified as equivalent variations etc.
Effect embodiment is applied to other fields, but every without departing from technical solution of the present invention content, according to technical spirit of the invention
Any simple modification, equivalent variations and the remodeling made to above example, still fall within the protection domain of technical solution of the present invention.
