[0002] The collimator is used to obtain a beam of light from infinity. This beam is called a collimator. It is an important tool for calibrating and adjusting optical instruments, and is also an important component of optical measuring instruments. When equipped with different graticules, together with the micrometer eyepiece or microscope system, the focal length, resolution, and other imaging qualities of the lens group can be measured. When in use, it is necessary to use a corresponding bracket.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. Example

[0022] Reference Figure 1-5As shown, a bracket for a collimator comprises a base 1, a lifting plate 2 is arranged on the top of the base 1, a rotating plate 3 is rotatably connected to the top of the lifting plate 2, a collimator body 4 is arranged on the top of the rotating plate 3, two T-shaped limiting grooves 6 are provided on one side of the top surface of the lifting plate 2, limiting blocks 7 are slidably inserted inside the limiting grooves 6, an embedded shaft 8 is inserted through the middle position of the limiting block 7, and both sides of the embedded shaft 8 are fixed to the inner walls of the limiting grooves 6 at adjacent positions, a threaded seat 11 is fixed on the top of the two limiting blocks 7, a first support rod 12 is hinged on the top of the threaded seat 11, the top of the first support rod 12 is hinged to the surface of the bottom of the rotating plate 3, and a bubble level 5 is fixed on the surface of one end of the rotating plate 3. The top surface of the lifting plate 2 is located at the middle position of the two parallel light tube bodies 4, and two symmetrically distributed fixing blocks 9 are fixed thereon. The surface at the middle position of the threaded seat 11 is threadedly connected with a first threaded rod 10. The first threaded rod 10 is rotatably connected to the two fixing blocks 9. The bubble level 5 can be used to determine whether the rotating plate 3 is in a horizontal state when supporting the parallel light tube body 4. By rotating the first threaded rod 10, the threaded seat 11 can move in a horizontal direction, so that the first support rod 12 can change its angle, so that the rotating plate 3 can change its angle so that it can be adjusted to a horizontal state, thereby ensuring that the parallel light tube body 4 is in a horizontal state when supported.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, two symmetrically distributed storage grooves 13 are provided on both sides of the top surface of the base 1, and symmetrically distributed first threaded sleeves 14 are slidably inserted on both sides of the inner cavity of the storage groove 13. The top of the first threaded sleeve 14 is hinged with a second support rod 15, and the top of the second support rod 15 is hinged with the surface of the bottom of the lifting plate 2, wherein the middle position of the two first threaded sleeves 14 is threadedly connected with a second threaded rod 16, and the second threaded rod 16 is rotatably connected to the inner cavity of the storage groove 13, and the middle position of the other two first threaded sleeves 14 is fixedly passed through a limited axis 17, and the two sides of the limited axis 17 are connected to the adjacent position storage The inner wall of the groove 13 is fixed. Since the inner wall of the storage groove 13 can play a role of interference and limitation on the first threaded sleeve 14 in the adjacent position, and since the external thread structures on both sides of the outer circumference of the second threaded rod 16 are arranged in opposite directions, when the second threaded rod 16 is rotated, the distance between the two first threaded sleeves 14 in the same storage groove 13 can be changed under the cooperation between the internal thread structure on the inner wall of the first threaded sleeve 14 and the corresponding external thread structure on the outer circumference of the second threaded rod 16, so that the second support rod 15 can change its angle, so that the height of the lifting plate 2 can be changed. Example

[0024] Further in the embodiments, please refer to Figure 4 and Figure 5 As shown, a rod groove 18 is provided on the surface of the top of the rotating plate 3, and a third threaded rod 19 is rotatably connected inside the rod groove 18. Second threaded sleeves 20 that are symmetrically distributed are threadedly connected on both sides of the outer circumference of the third threaded rod 19, and a connecting frame 21 is fixed on the top of the second threaded sleeve 20. Since the inner wall of the rod groove 18 can play a role of interference and limitation on the two second threaded sleeves 20 and the external thread structures on both sides of the outer circumference of the third threaded rod 19 are arranged in opposite directions to each other, when the third threaded rod 19 is rotated, the distance between the two second threaded sleeves 20 can be changed under the cooperation between the internal thread structure on the inner wall of the second threaded sleeve 20 and the external thread connection on the outer circumference of the third threaded rod 19, thereby allowing the distance between the two connecting frames 21 to change.

[0025] Please refer to Figure 4 and Figure 5 As shown, an embedded rod 22 is fixed to the inner cavity surface of the connecting frame 21, and clamp seats 23 are slidably sleeved on both ends of the outer circumference of the embedded rod 22. The ends of the two adjacent clamp seats 23 that are close to each other fit with the outer circumference of the parallel light tube body 4. A spring 24 is sleeved on the outer circumference of the embedded rod 22 at a position at one end of the adjacent clamp seat 23. One side of the spring 24 is fixed to the inner cavity surface of the adjacent connecting frame 21, and the other side of the spring 24 is fixed to the surface of the adjacent clamp seat 23. When the parallel light tube body 4 is placed inside the two groups of clamp seats 23, the clamp seats 23 can contact the adjacent springs 24 to deform them, so that the two groups of clamp seats 23 can clamp and fix the parallel light tube body 4 under the action of the rebound force of the springs 24.

[0026] Working principle: In actual use, when the user needs to fix and support the collimator body 4, firstly, the user observes the bubble level 5 to determine whether the rotating plate 3 is in a horizontal state. If it is in a horizontal state, the collimator body 4 can be directly supported and fixed. When it is not in a horizontal state, the first threaded rod 10 is rotated. Due to the limiting effect of the embedded shaft 8 on the limit block 7, the threaded seat 11 can only move in the horizontal direction. Therefore, when the first threaded rod 10 is rotated, the threaded seat 11 can move in the horizontal direction under the cooperation of the threaded structure between the first threaded rod 10 and the threaded seat 11, so that the angle of the first support rod 12 can be changed to adjust the rotating plate 3 to a horizontal state, and then the collimator body 4 is fixed as required. The length of the collimator body 4 is adjusted to adjust the distance between the two connecting frames 21, and the collimator body 4 is placed inside the two groups of clamp seats 23, so that the clamp seats 23 can contact the springs 24 at the adjacent positions to deform them, so that the two groups of clamp seats 23 can clamp and fix the collimator body 4 under the action of the rebound force of the springs 24. When it is necessary to adjust the supporting height of the collimator body 4, by rotating the second threaded rod 16, the internal thread structure on the inner wall of the first threaded sleeve 14 and the corresponding external thread structure on the outer circumference of the second threaded rod 16 can change the distance between the two first threaded sleeves 14 in the same storage groove 13, so that the angle of the second support rod 15 can change, so that the height of the lifting plate 2 can change.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
