DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0027] Please refer to Figures 1-2 The utility model discloses a kind of splitters, comprising: splitter body 1, splitter body 1 is provided with cavity 13, cavity 13 is provided with light inlet 11 and two different light outlets with communication arrangement. Coaxial with light inlet 11 is first light outlet 14, and second light outlet 15 is angularly deflected with light inlet 11.

The upper side of cavity 13 is also provided with observation window 16, to facilitate operator observation the situation in cavity 13.
[0028] Please refer to Figures 2-5 Cavity 13 is provided with optical path assembly 2.
[0029] Specifically, optical path assembly 2 includes displacement table 21, in some embodiments, cavity 13 is also provided with the slide rail of cooperation displacement table 21 and carries out linear movement. Displacement table 21 is detachably connected with reference plate 22, connection mode includes but is not limited to bolt connection, and displacement table 21 is provided with scale, for providing reference to the relative position of reference plate 22 and displacement table 21. Wherein, reference plate 22 is L-shaped.
[0030] Further, one side of reference plate 22 is provided with mirror frame 23, and lens 24 is fixedly installed on mirror frame 23, and lens 24 is used to reflect light wave. Mirror frame 23 is connected with reference plate 22 through multiple springs. Spring includes tension spring 25, and optical axis light rod 26 is connected to the both ends of tension spring 25, and the optical axis light rod 26 connected to one end of tension spring 25 is fixedly installed on reference plate 22, and the optical axis light rod 26 connected to the other end of tension spring 25 is fixedly installed on mirror frame 23.
[0031] Please refer to Figures 2-4 Figures 2-4As shown, the light path assembly 2 is connected to the adjusting assembly 3, and the adjusting assembly 3 is used to adjust the position of the lens 24.
[0032] Specifically, the adjusting assembly 3 includes three screw feed devices, which include a screw rod, a handle knob and a rod, and since the screw feed device is prior art, it will not be described in detail here. The three screw feed devices are respectively a first screw feed device 31, a second screw feed device 32 and a third screw feed device 33.
[0033] The rod at the end of the first screw feed device 31 penetrates the reference plate 22 and abuts against the frame 23, and correspondingly, the rod at the end of the second screw feed device 32 also penetrates the reference plate 22 and abuts against the frame 23, and the rod at the end of the third screw feed device 33 is fixedly connected to the displacement table 21. Rotating the handle knob of the first screw feed device 31 can make the rod at the end thereof move linearly, so as to make the lens 24 on the frame 23 rotate in the X-Y plane, and the rotation angle of the lens 24 in the X-Y plane can be adjusted by adjusting the number of rotation of the handle knob. Correspondingly, the second screw feed device 32 can adjust the rotation angle of the lens 24 in the Z-X plane. The third screw feed device 33 can adjust the position of the displacement table 21 in the X direction, and the displacement table 21 moves to drive the frame 23 and the lens 24 to move, so as to adjust the position of the lens 24 in the X direction.
[0034] If the rotation angle of the lens 24 is too large and needs to be adjusted, the handle knob of the first screw feed device 31 or the handle knob of the second screw feed device 32 is reversely rotated, and under the action of the tension spring 25, the lens 24 is gradually adjusted.
[0035] In the embodiment, the beam splitter is installed behind an optical instrument (such as a laser), so that the laser emitted from the light outlet of the optical instrument enters the light inlet 11 of the beam splitter body 1, and the adjusting assembly 3 cooperates with the light path assembly 2 to change the light path propagation direction, so that the light wave emitted from one optical instrument can be emitted from two different light outlets (the first light outlet 14 or the second light outlet 15) of the beam splitter, without the need to replace the optical instrument with different light path propagation directions, and without the need to debug the optical instrument again for the vacuum propagation of the light wave, and the utilization rate of the optical instrument is improved.
[0036] In use, first install the lens 24 on the frame 23, then adjust the tilt posture of the lens 24 (i.e. the rotation angle of the lens 24 in the X-Y plane and the rotation angle in the Z-X plane) through the first lead screw feeding device 31 and the second lead screw feeding device 32, so that the lens 24 is adjusted to the required exit angle of the light path. After the exit angle adjustment is completed, the displacement table 21 is moved to the preset position through the third lead screw feeding device 33, so that the light waves entering at the light inlet 11 can be reflected by the lens 24 and then emitted from the second light outlet 15. When the light waves need to be emitted from the first light outlet 14, only the third lead screw feeding device 33 needs to be adjusted to reset the displacement table 21, at this time, there is no lens 24 shielding and reflecting between the light inlet 11 and the first light outlet 14, and the light waves can be directly emitted from the light inlet 11 to the first light outlet 14, without adjusting the first lead screw feeding device 31 and the second lead screw feeding device 32, so as to realize the function of changing the light path propagation direction without changing the posture of the lens 24. When adjusting the displacement table 21, the movement of the lens 24 in the X direction can also be observed in real time through the observation window 16.
[0037] In some embodiments, a limiting rod can also be installed on the displacement table 21 or the reference plate 22, the length of the limiting rod is determined according to the first adjustment of the position of the displacement table 21 in the X direction, so that when the displacement table 21 is moved subsequently, the limiting rod can be in contact with the inner wall of the cavity 13 as soon as the lens 24 reaches the preset station, without the need to adjust the lens 24 every time.
[0038] The working principle of the utility model is: in use, first install the lens 24 on the frame 23, then adjust the tilt posture of the lens 24 (i.e. the rotation angle of the lens 24 in the X-Y plane and the rotation angle in the Z-X plane) through the first lead screw feeding device 31 and the second lead screw feeding device 32, so that the lens 24 is adjusted to the required exit angle of the light path. After the exit angle adjustment is completed, the displacement table 21 is moved to the preset position through the third lead screw feeding device 33, so that the light waves entering at the light inlet 11 can be reflected by the lens 24 and then emitted from the second light outlet 15. When the light waves need to be emitted from the first light outlet 14, only the third lead screw feeding device 33 needs to be adjusted to reset the displacement table 21, at this time, there is no lens 24 shielding and reflecting between the light inlet 11 and the first light outlet 14, and the light waves can be directly emitted from the light inlet 11 to the first light outlet 14, without adjusting the first lead screw feeding device 31 and the second lead screw feeding device 32, so as to realize the function of changing the light path propagation direction without changing the posture of the lens 24.
[0039] The above has carried out the detailed explanation to one embodiment of the utility model, but the content described is only the preferred embodiment of the utility model, cannot be considered for limiting the implementation scope of the utility model. All equal changes and improvements etc. that are made in the utility model application scope should still belong to the claim coverage scope of the utility model.
