Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of experimental equipment, in particular to a prism holder. Background Art
[0002] At present, in the in-vivo calcium imaging experiment, the experimental equipment of the experimenter is a support arm and a microscope and a prism thereon. Among them, the prism is connected to the bottom of the support arm through a skirt sleeve, and the prism is aligned with the bottom end of the microscope. Then, the prism is implanted in the mouse brain, and the experimenter can observe the flow and transmission of mouse nerve signals between neural networks through the microscope.
[0003] In the process of using the existing skirt sleeve, since it is not convenient to replace the prism on the skirt sleeve, the use and operation effect of the experimenter is not good. Therefore, for the progress of the industry technology, to better realize the function of replacing the prism and improve the core technology competitiveness, this application proposes a new implementation scheme different from the prism connection, clamping and fixing structure and the use method in the prior art. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem that the prism on the existing skirt sleeve is not convenient to replace, resulting in poor use and operation effect of the experimenter, and to propose a prism holder.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A prism holder includes a holder body. The holder body includes a main block and a sub-block. A side groove is provided on one side of the main block. A movable shaft is fixedly inserted between the top inner wall and the bottom inner wall of the side groove. A convex block is fixedly connected to one side of the sub-block. The convex block is rotatably sleeved on the movable shaft. Clamping grooves are provided on one side of the sub-block and one side of the main block. Limiting notch openings are provided on one side of the convex block and one inner wall of the side groove. A spring is clamped between the two limiting notch openings.
[0007] Further, a mounting hole is provided on the top of the main block.
[0008] Further, a plurality of anti-slip strips are fixedly connected to one side of the main block and one side of the sub-block.
[0009] Further, outer grooves are provided on one side of the main block and one side of the sub-block.
[0010] The beneficial effects of the utility model are:
[0011] 1. By pinching the main block and the secondary block inward, the secondary block rotates outward, thereby opening the clamping grooves of the main block and the secondary block. Then, the prism is clamped in the clamping groove of the main block, and under the elastic action of the spring, the secondary block rotates towards the main block, thus clamping the prism tightly. The operation is simple, convenient and fast.
[0012] 2. The provision of the anti-slip strips can increase the friction between the main block and the secondary block and the hand, thereby facilitating the pinching of the main block and the secondary block, and further facilitating the clamping of the prism. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0022] Refer to Figures 1-7, a prism holder, comprising a holder body 1. The holder body 1 includes a main block 101 and a sub-block 102. A side groove 1011 is provided on one side of the main block 101. A movable shaft 106 is fixedly inserted between the top inner wall and the bottom inner wall of the side groove 1011. A convex block 1021 is integrally formed on one side of the sub-block 102. The convex block 1021 is rotatably sleeved on the movable shaft 106. Clamping grooves 103 are provided on one side of the sub-block 102 and one side of the main block 101. Limiting notch openings 104 are provided on one side of the convex block 1021 and one side inner wall of the side groove 1011. A spring 105 is clamped between the two limiting notch openings 104. By squeezing the main block 101 and the sub-block 102 inward, the sub-block 102 rotates outward, and then the clamping grooves 103 of the main block 101 and the sub-block 102 are opened. Then, the prism is clamped in the clamping groove 103 of the main block 101, and then under the elastic action of the spring 105, the sub-block 102 rotates toward the main block 101, thereby clamping the prism tightly.
[0023] An installation hole 2 is provided at the top of the main block 101. A bolt is inserted into the installation hole 2 to fix the holder body 1 at the bottom of the support arm. A plurality of anti-slip strips 3 are integrally formed on one side of the main block 101 and one side of the sub-block 102. The design of the anti-slip strips 3 increases the frictional force between the main block 101 and the sub-block 102 and the hand, thereby facilitating the squeezing of the main block 101 and the sub-block 102. Outer grooves 4 are provided on one side of the main block 101 and one side of the sub-block 102.
[0024] The working principle of this embodiment: When in use, first, a bolt is inserted into the installation hole 2 to fix the holder body 1 at the bottom of the support arm. Then, the main block 101 and the sub-block 102 are squeezed inward, so that the sub-block 102 rotates outward, and then the clamping grooves of the main block 101 and the sub-block 102 are opened, and at the same time the spring 105 contracts. Then, the prism is clamped in the clamping groove 103 of the main block 101, and then under the elastic action of the spring 105, the sub-block 102 rotates toward the main block 101, thereby clamping the prism tightly.
[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
