Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
An embodiment of an external fixing frame system of the present utility model, an external fixing frame system, includes two fixing rings, an adjusting rod is disposed between the two fixing rings, the adjusting rod is as shown in fig. 1 to 4, the adjusting rod includes a rod body 5 extending along an up-down direction and a connector 3 disposed at an upper end of the rod body 5, and the connector 3 is integrally in a hollow cylinder structure. The upper end of connector 3 is equipped with the installation department that is arranged in the connecting hole of solid fixed ring of cartridge, is equipped with installation nut 2 on the installation department, is equipped with the bulb on the body of rod 5, and the lower extreme of connector 3 is equipped with and holds the chamber with bulb normal running fit, is equipped with the through-hole with holding the chamber intercommunication on the connector 3, screw thread install with hold the ejector pin 1 of bulb locking in the chamber in the through-hole, the upper end of ejector pin is equipped with the screw up head, specifically is six arriss structures for screw up the operation, the lower extreme of ejector pin is groove structure, improves area of contact.
In this embodiment, the mounting portion of the connector is specifically a hollow rod-shaped structure, the diameter of the mounting portion is matched with the size of the mounting hole on the fixing ring, a blocking table 31 is arranged at the lower end of the mounting portion, and the blocking table 31 is used for blocking the lower side of the fixing ring. The outer periphery of the mounting part is provided with external threads for mounting the mounting nut 2, so that the mounting nut can be locked and fixed on the fixing ring.
In this embodiment, the lower end of the connector 3 is provided with more than two spring claws 32 distributed circumferentially, the outer ends of the spring claws 32 enclose a containing cavity, and the side surfaces of the spring claws are provided with threads and are provided with lock nuts 4. Specifically, four elastic claws are uniformly distributed in the circumferential direction, and the elastic claws are in an outward expansion state in an initial state, so that the ball head can enter and exit the accommodating cavity.
