DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to enable those skilled in the art to better understand the present disclosure, the technical solution of the present disclosure is further elaborated in combination with the attached drawings and the embodiment.

[0023] As shown in FIG. 1 to FIG. 4, the embodiment of the technical solution of the present disclosure includes: a collector lens base 1, a microscope base 13, a Kohler collector lens 2, an non-Kohler collector lens 3, a wrench 4, a TEC collector lens 5, a circular cavity 9, 10, square through-holes 7, 12, insertion bars 6a, 6b, insertion holes 8a, 8b, a female end slot 1a, male end snap buckles 2a, 2c, 2d, 2e, male end snap buckles 3a, 3c, 3d, 3e, female annular internal gear 4a and male end snap buckles 5a, 5c, 5d and 5e.

[0024] As shown in FIG. 1 and FIG. 3, the collector lens base 1 is provided with a circular cavity 10, which is matched with the circular cavity 9 of the microscope base, and the collector lens base is inserted in the circular cavity 9. The collector lens base 1 is provided with six square through-holes 7, and the six square through-holes 7 are matched with the six square through-holes 12 in the microscope base, and the square through-holes 7 and 12 play the role of heat dissipation of the light source in the microscope base.

[0025] The collector lens base 1 is provided with two insertion bars 6a and 6b, which are inserted into the insertion holes 8a and 8b of the microscope base to make the collector lens base 1 fit and fix on the microscope base.

[0026] As shown in FIG. 1, FIG. 2 and FIG. 4, the collector lens base 1 is provided with female end slot 1a. In this embodiment, the number of preferred female end slots is four 1a, 1b, 1c and 1d, and the female end slots are used to match with the snap buckle on the collector lens, so that the collector lens is snapped on the collector lens base 1 through the snap buckle. Preferably, the collector lens in this embodiment takes the Kohler collector lens 2, the non-Kohler collector lens 3 and the TEC collector lens 5 as examples, there are four male end snap buckles for the Kohler collector lens 2, the non-Kohler collector lens 3 and the TEC collector lens 5 respectively, which are matched with the collector lens base 1. The male end snap buckles of the Kohler collector lens 2 are 2a, 2c, 2d and 2e, the male end snap buckles of the non-Kohler collector lens 3 are 3a, 3c, 3d and 3e, and the male end snap buckles of the TEC collector lens 5 are 5a, 5c, 5d and 5e.

[0027] The male end of the collector lens is matched with the female end of the wrench in correspondence. The male end of the collector lens may be in a certain shape of one of quincunx, square, hexagon, pentagon, gear, etc., and the male end of the collector lens is preferably a gear shape. Since the male end of the collector lens is made into quincunx, square, hexagon, pentagon and other shapes, the collector lens can be easily disassembled by hand screwing or simple common tools. While the male end of the collector lens produces gears to form a male end gear, since it is difficult to find a matching special tool for the internal gear, the collector lens is not easy to be disassembled. The matching of the male end gear of the collector lens and the internal gear wrench can prevent the loss and damage of the collector lens.

[0028] The distance between the collector lens and the light source is 5-9 mm, so as to prevent the collector lens from being too close to the light source. The lower part of the male end gear of the collector lens is long or short, and the distance between the collector lens and the light source is different, and a certain distance range should be maintained when the collector lens is installed.

[0029] In this embodiment, male end gears 2b, 3b and 5b are provided on the preferred the Kohler collector lens 2, the non-Kohler collector lens 3 or the TEC collector lens 5. The male end gears 2b, 3b and 5b are used together with the female end annular internal gear 4a provided on the wrench 4. The diameter 11 of the wrench 4 is the same as the diameter of the collector lens, in the present embodiment, the preferred diameter 11 of the wrench 4 is 68 mm, and the depth of the wrench is ≥20 mm, so as to achieve the real-time matching between the wrench 4 and the male end gears 2b, 3b, 5b on the collector lens, to ensure that the female end annular internal gear 4a on the wrench 4 is matched with the male end gears 2b, 3b, 5b on the collector lens when using, such that the collector lens can be tighten or loosen when the wrench 4 is rotated clockwise or counterclockwise, achieving the purpose of removing or installing the collector lens, so that the interchangeability of the collector lens can be realized

[0030] Through the rotation of the wrench, the present disclosure tightens and loosens the Kohler collector lens, the non-Kohler collector lens or the TEC collector lens, so as to realize the interchangeability of the Kohler collector lens, the non-Kohler collector lens or the TEC collector lens, which can be positioned correctly, stably and repeatedly, so as to meet the requirements of the user. The present disclosure has the advantages of convenient operation, simple structure, strong function and low cost.

[0031] A detailed introduction to the interchangeable collector lens lens device of a microscope provided by the present disclosure is described above. It can realize the replacement of the collector lens lens of the microscope, improve the replacement efficiency, and meet the requirements of exchanging the collector lens lens under different conditions without disassembly. The description of the embodiment is only used to help understand the method and the core idea of the present disclosure. It should be pointed out that for ordinary skilled person in the art, on the premise of not departing from the principle of the present disclosure, a number of improvements and modifications can be made to the present disclosure, and these improvements and modifications are within the scope of the claims of the present disclosure.
