Detailed Description

In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.

As shown in fig. 1-3, in the embodiment of the present utility model: the interface structure of the combined sighting telescope comprises a middle tube 110, wherein joint mechanisms are arranged at the left end and the right end of the middle tube 110, and each joint mechanism comprises an outer connecting tube 120 and a clamping piece 130;

the outer connecting pipe 120 is connected to the end face of the middle pipe 110, the outer wall of the outer connecting pipe 120 is provided with a threaded strip, the right side of the outer connecting pipe 120 is uniformly connected with four groups of ring pieces 121, the ring pieces 121 are made of plastic, the ring pieces 121 can generate good deformation effect after being extruded, meanwhile, the ring pieces have good resetting property after being deformed, gaps exist between two adjacent groups of ring pieces 121, the right side of the ring pieces 121 can be clamped inwards after being extruded, and the eyepiece is clamped;

the left side of the clamping piece 130 is provided with a thread groove 131 which can be in threaded connection with the outer wall of the outer tube 120, the thread groove 131 and the outer tube 120 can be in threaded fit, relative displacement can be generated after mutual rotation, the right side of the thread groove 131 is provided with a butt hole 132 which penetrates through the clamping piece 130, the butt hole 132 gradually decreases from left to right, and after the outer tube 120 is connected with the thread groove 131, the butt hole 132 can squeeze the ring 121.
