[0024] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0025] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0026] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0027] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0028] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0029] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0030] Beneficial effects of the present disclosure:

[0031] It can clamp and fix the endoscope used in the operation, and stabilize the endoscope. At the same time, it can also adjust the position and angle of the clamping bar according to the position of the endoscope, and is suitable for stabilizing the endoscope in a variety of scenarios.
