A tension spring 104e is sleeved on the outer wall of the clamping rod 104d. The tension spring 104e is a carbon spring with high strength. One end of the tension spring 104e is fixedly connected to the At the top of the inner wall of the auxiliary groove 104b, a limiting rod 104f is fixedly connected to one side of the outer wall of the clamping rod 104d, straight grooves 104g are provided on both sides of the upper end surface of the bottom end of the installation groove 101b, and an arc groove 104h is provided at one end of the straight groove 104g. One end of the limiting rod 104f is slidably connected in the straight groove 104g and the arc groove 104h, and positioning blocks 104i are provided on both sides of the inner wall of the installation groove 101b, and the clamping rod 104d is correspondingly clamped on the positioning blocks 104i.

[0038] By further limiting the structure of the mounting strip 101a, auxiliary areas for mounting the clips 104 are formed on both sides of the mounting strip 101a, and then the mounting strip 101a is rotatably connected to the auxiliary groove 104b through the clip rod 104d. At the same time, one end of the limit rod 104f on the clip rod 104d is slidably connected to the straight groove 104g and the arc groove 104h, so that the clip rod 104d is correspondingly clamped on the positioning block 104i, giving the mounting strip 101a stability before being fixed.

[0039] The rest of the structure is the same as that of Example 1.

[0040] When installing the endoscope 202, first pull the insertion rod 103b downward to deform the compression spring 103c. At this time, the installation strip 101a on the installation block 202b is aligned with the installation groove 101b, so that the installation strip 101a slides into the installation groove 101b. At this time, one end of the limit rod 104f is slidably connected to the straight groove 104g, and then the first insertion block 101d cooperates with the second insertion block 102a to form a stable round hole structure. At the same time, one end of the limit rod 104f slides It is connected in the arc groove 104h, so that the clamping rod 104d rotates on the shaft seat 104c. At this time, the clamping rod 104d is correspondingly clamped on the positioning block 104i, which ensures the stability of the endoscope during installation. Then the insertion rod 103b is loosened, and the insertion rod 103b is driven to be inserted into the circular hole and the clamping groove under the action of the compression spring 103c. In this way, the position of the first insertion block 101d and the second insertion block 102a is limited by the locking piece 103, which ensures the rapid installation and removal of the spinal endoscope.
