[0036] With reference to Figure 2 、 Figure 5 With Figure 6 , the outer wall of the moving rod 32 is connected with the inner wall of the extension pipe 24 through the connecting assembly 35, the connecting assembly 35 comprises a connecting ball 351, the outer wall of the connecting ball 351 is fixedly connected with the outer wall of the moving rod 32, the shape of the connecting ball 351 is that of a sphere connected with a cylinder, and the end of the cylinder part of the connecting ball 351 is fixedly connected with the outer wall of the moving rod 32, the outer part of the connecting ball 351 is provided with a spherical sleeve 352, the shape of the spherical sleeve 352 is that of an incomplete hollow sphere connected with a cylinder, and the sphere part of the spherical sleeve 352 is greater than one half of the whole sphere, the hollow part of the spherical sleeve 352 is in the shape of a sphere, and the shape of the hollow part of the spherical sleeve 352 is matched with the shape of the sphere part of the connecting ball 351, the outer wall of the spherical sleeve 352 is fixedly connected with the outer wall of the extension pipe 24, the connecting ball 351 is arranged in the inside of the hollow part of the spherical region of the spherical sleeve 352, and the end of the cylinder part of the spherical sleeve 352 is fixedly connected with the outer wall of the extension pipe 24.

[0037] Working principle: in use, during installation, the workers first move the whole of the positioning block 26 and the extension pipe 24 to the outside of the entering rod 21 at an arbitrary angle, and then slowly move towards the direction of the positioning rod 23, because the shape of the entering rod 21 is a cylinder, so the positioning block 26 can be sleeved on the outside of the entering rod 21 at an arbitrary direction.

[0038] When the positioning block 26 moves to the outside of the deformation rod 22, since the deformation rod 22 slowly deforms, the positioning block 26 can slowly rotate to a position consistent with the shape of the front end of the deformation rod 22 during the movement of the positioning block 26, so that the positioning block 26 can be more easily moved to the outside of the positioning rod 23 after continuing to move, thus achieving the effect of convenient installation.

[0039] During use of the device, when vibration occurs, when the whole composed of the extension pipe 24 and the positioning block 26 moves relative to the disc body 1, the moving rod 32 close to the direction moves towards the direction of the air pressure pipe 31, thus driving the end connected with the connecting rod 34 to move, so that the projection length of the connecting rod 34 in the sliding direction of the sliding plate 33 connected with the connecting rod 34 becomes shorter, thus driving the two sliding plates 33 to move towards each other, so that the air pressure in the area between the two sliding plates 33 increases, facilitating the whole composed of the extension pipe 24 and the positioning block 26 to quickly reset after vibration occurs.

[0040] When the whole composed of the extension pipe 24 and the positioning block 26 and the driving assembly 2 move along the axial direction of the entering rod 21, at this time, all the moving rods 32 move away from the air pressure pipe 31, thus driving the end connected with the connecting rod 34 to move, so that the projection length of the connecting rod 34 in the sliding direction of the sliding plate 33 connected with the connecting rod 34 increases.

[0041] Thus, the air pressure in the space between the two sliding plates 33 connected with the same moving rod 32 decreases, while the air pressure in the space between the two adjacent sliding plates 33 connected with different moving rods 32 increases, so that the extension pipe 24 and the positioning block 26 still have strong recovery ability at this time, thus facilitating the whole composed of the extension pipe 24 and the positioning block 26 to quickly reset after vibration occurs.

[0042] Finally, it should be noted that the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
