[0001] The utility model relates to the technical field of optical instrument microscopes, in particular to an optical instrument microscope. Background Art
[0002] A microscope is an optical instrument composed of one lens or a combination of several lenses. It is a symbol of mankind entering the atomic age. Microscopes are mainly used to magnify tiny objects so that they can be seen by the naked eye. Microscopes are divided into optical microscopes and electron microscopes: The optical microscope was first invented by Janssen of the Netherlands in 1590. Today's optical microscopes can magnify objects 1600 times, and the minimum resolution limit is 1 / 2 of the wavelength. The length of the mechanical tube of a domestic microscope is generally 160 mm.
[0003] A fixing component for limiting the slide is provided on the slide stage of an existing microscope, and the fixing component usually includes a clamp that is fixed by unilateral rotation. Since the rotation range of the fixing clamp is limited, it is impossible to effectively fix a shorter slide. Therefore, this type of microscope that fixes the slide by unilateral rotation has great limitations in use and cannot meet the fixation requirements for slides of different lengths. For this reason, we provide an optical instrument microscope. Utility Model Content

[0006] As a preferred implementation, two ends of the spring are fixedly connected to the outer surface of the limit block and the inner wall of the glass stage respectively, and a rotating rod passes through the interior of the toothed disc.
[0007] As a preferred implementation, the rotating rod is fixedly connected to the gear disc, and a bearing is sleeved on the outer surface of the rotating rod.
[0008] As a preferred embodiment, the bearing is fixedly connected to the outer surface of the rotating rod and the inner wall of the glass stage, and an adjusting rod is fixedly connected to one end of the rotating rod close to the gear disk.

[0011] As a preferred implementation, a silicone pad is provided at the bottom of the spring sheet, and the silicone pad is fixedly connected to the spring sheet.
[0012] Compared with the prior art, the advantages and positive effects of the utility model are:
[0013] The utility model provides a fixing mechanism so that the optical instrument microscope can fix glass slides of different lengths and thicknesses, and the fixing mechanism can be rotated and adjusted, so that even a glass slide of a shorter length can be firmly fixed, thereby ensuring the observation accuracy of the microscope body.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Example 1
[0027] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: an optical instrument microscope, comprising: a microscope body 1, a glass stage 2 is provided on the microscope body 1, a fixing mechanism 3 is provided inside the glass stage 2, the number of the fixing mechanisms 3 is two, the fixing mechanism 3 comprises a toothed disc 31, a slot 32 is provided on the toothed disc 31, an arc surface 33 is provided on the toothed disc 31, a semicircular block 34 is provided on one side of the toothed disc 31, a connecting block 35 is fixedly connected to one end of the semicircular block 34, the connecting block 35 passes through the inside of the glass stage 2, the connecting block 35 is slidably connected to the glass stage 2, one end of the connecting block 35 away from the semicircular block 34 is fixedly connected to a limiting block 36, a spring 37 is provided on one side of the limiting block 36, two ends of the spring 37 are respectively fixedly connected to the outer surface of the limiting block 36 and the inner wall of the glass stage 2, and a rotating rod 38 passes through the inside of the toothed disc 31.
[0028] The toothed disc 31 is provided with a slot 32, and the slot 32 is matched with the semicircular block 34, so that the semicircular block 34 can maintain the stability of the toothed disc 31 by tightly engaging with the slot 32. In addition, the toothed disc 31 is provided with an arc surface 33, and the arc surface 33 is used to cooperate with the curved surface of the semicircular block 34, so that the toothed disc 31 can be smoothly squeezed and adjusted on the semicircular block 34, so as to achieve the purpose of rotating the toothed disc 31. The connecting block 35 and the limiting block 36 are provided to connect the semicircular block 34 and the spring 37. At the same time, the elastic force of the spring 37 can only reset the semicircular block 34 to the appropriate position. In addition, the provision of the spring 37 makes it more convenient for the semicircular block 34 to fix the toothed disc 31. At the same time, the elastic force of the spring 37 can also continuously squeeze the semicircular block 34 in the opposite direction in a static state, so as to fix the toothed disc 31.
[0029] Example 2
[0030] like Figure 1-Figure 6 As shown, the rotating rod 38 is fixedly connected to the toothed disc 31, and a bearing 39 is sleeved on the outer surface of the rotating rod 38. The bearing 39 is fixedly connected to the outer surface of the rotating rod 38 and the inner wall of the glass stage 2. An end of the rotating rod 38 close to the toothed disc 31 is fixedly connected to an adjusting rod 301, and a cover plate 302 is sleeved on the outer surface of the adjusting rod 301. The cover plate 302 is fixedly connected to the adjusting rod 301. A spring piece 303 passes through the outer surface of the adjusting rod 301, and the spring piece 303 is fixedly connected to the adjusting rod 301. A silicone pad 304 is provided at the bottom of the spring piece 303, and the silicone pad 304 is fixedly connected to the spring piece 303.
[0031] In this embodiment, by providing a rotating rod 38 and a bearing 39, utilizing the special properties of the bearing 39 and under the connection of the rotating rod 38, the toothed disc 31 can rotate, and a spring piece 303 is provided. Utilizing the elasticity of the spring piece 303, it can adapt to glass slides of different thicknesses, and the spring piece 303 will also generate elastic force when being bent, thereby tightly fixing the glass slide. In addition, a silicone pad 304 is fixedly connected to the bottom of the spring piece 303. Due to the soft texture of the silicone pad 304, the spring piece 303 will not scratch the glass slide, and the silicone pad 304 can increase the contact friction between the spring piece 303 and the glass slide, further ensuring the stability of the glass slide when used.
[0032] Working principle:
[0033] like Figure 1-Figure 6As shown, when the utility model is in use, the spring pieces 303 in the two fixing mechanisms 3 can be adjusted for use angles according to the length of the glass slide used. At this time, the spring piece 303 is rotated, and the toothed disc 31 will rotate at a corresponding angle under the drive of the adjusting rod 301. When the toothed disc 31 rotates, the arc surface 33 will be used to squeeze the semicircular block 34, so that the semicircular block 34 drives the connecting block 35 and the limiting block 36 to slide inside the glass slide table 2, and the limiting block 36 will compress the spring 37 at the same time, so that the spring 37 generates an elastic force. At this time, when the semicircular block 34 is not in contact with the arc surface 33 provided on the toothed disc 31, the elastic force of the spring 37 will be instantly released, and the semicircular block 34 will be reset, so that it will be tightly engaged with the card slot 32 provided on the toothed disc 31. At this time, when the use angle of the spring piece 303 is appropriate, the rotation of the spring piece 303 can be stopped. If the use angle of the spring piece 303 is not appropriate, the spring piece 303 can be continued to be rotated, and the squeezing adjustment of the semicircular block 34 by the toothed disc 31 is repeated until the use angle of the spring piece 303 is at the optimal position. When the toothed disc 31 rotates, the inner diameter circle of the bearing 39 is driven by the rotating rod 38 to rotate, so as to keep the toothed disc 31 able to rotate stably. Finally, the glass slide is placed on the glass slide table 2, and the spring piece 303 is bent and lifted so that the edge of the glass slide is at the bottom of the spring piece 303, and the spring piece 303 is released. The glass slide is tightly fixed by the elastic force of the spring piece 303, and then another spring piece 303 is rotated and adjusted using a similar method until the glass slide is fixed.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
