Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to the following specific embodiments, which are not intended to limit the present invention.

In the description of the present invention, it is to be understood that the terms "end", "outer", "inner", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Example 1

A glass instrument fixing clip comprises a first fastening ring 1 and a second fastening ring 2 which are of a semi-circular ring structure, wherein the first fastening ring 1 and the second fastening ring 2 can be enclosed to form a circular ring structure;

two ends of the first fastening ring 1 are respectively provided with a first threaded hole, two ends of the second fastening ring 2 are respectively provided with a second threaded hole corresponding to the first threaded hole, and the fastening bolt 11 can simultaneously penetrate through the first threaded hole and the adjacent second threaded hole to connect the first fastening ring 1 and the second fastening ring 2; when the glass instrument clamping device is used, the glass instrument can be clamped in the middle of the annular structure, and the inner size of the annular structure can be adjusted through the fastening bolt 11, so that glass instruments with different outer diameters can be clamped;

because the glass instrument belongs to a fragile object, the glass instrument is easy to break when the applied acting force is large, so in order to effectively control the acting force for clamping the glass instrument, a third fastening ring 3 and a fourth fastening ring 4 which are of a semi-circular structure are arranged in the circular structure, and the third fastening ring 3 and the fourth fastening ring 4 can be encircled to form the circular structure; the third fastening ring 3 and the first fastening ring 1, and the fourth fastening ring 4 and the second fastening ring 2 are respectively connected through springs 5; the inner sides of the third fastening ring 3 and the fourth fastening ring 4 are respectively provided with a buffer layer made of polytetrafluoroethylene, the polytetrafluoroethylene can effectively resist chemical corrosion and is durable, the structure of the material is not a rigid structure and has certain buffer force, and when a glass instrument is clamped in a ring surrounded by the third fastening ring 3 and the fourth fastening ring 4 together, the buffer layer made of the material can play a role of buffering, so that the glass instrument is prevented from being damaged due to large acting force suddenly applied to the fastening bolt 11; in addition, the spring 5 also has the same buffer function; because the spring connection does not belong to the fixed connection, in order to prevent the third fastening ring 3 and the fourth fastening ring 4 from shaking randomly and enable the spring 5 to achieve the buffer effect, the spring 5 can be set as a rigid spring, and the spring can be specifically selected by a person skilled in the art during implementation;
