Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Through the setting of the two connection grooves 21, it is ensured that the two connection grooves 21 are axially symmetrically distributed with the center line of the connection block 1 in the left and right directions as the symmetry axis.

[0034] Reference Figure 2 、 Figure 3 and Figure 6 The connecting groove 21 is provided with a guide assembly 22, which includes a movable groove 221. The width of the movable groove 221 is smaller than the width of the connecting groove 21, and the shape of the movable groove 221 is consistent with the shape of the connecting groove 21. The movable groove 221 is opened on the inner wall of the connecting block 1 outside the connecting groove 21. The connecting groove 21 is provided with a rotating sleeve 222. The diameter of the rotating sleeve 222 matches the width of the connecting groove 21, and the radius length of the rotating sleeve 222 is greater than the top end position of the movable groove 221. The shortest distance between the rotating sleeve 222 and the outer wall of the connecting block 1 is ensured by setting the radius length of the rotating sleeve 222 and the shortest distance between the end of the movable groove 221 and the outer wall of the connecting block 1, so as to ensure that when the rotating sleeve 222 is in the end position, there is a part of the rotating sleeve 222 outside the connecting block 1, the inner wall of the rotating sleeve 222 is penetrated by the rotating shaft 223, the rotating shaft 223 penetrates the inner wall of the movable groove 221, the outer wall of the rotating shaft 223 is slidably connected to the rotating cylinder 224, and the outer wall diameter of the rotating cylinder 224 is smaller than the inner wall diameter of the rotating sleeve 222.

[0035] Reference Figure 2 、 Figure 3 and Figure 6The inner wall of the rotating drum 224 is provided with a movable groove 225, which is in the shape of a rectangular parallelepiped. A slide plate 226 is slidably connected to the inner wall of the movable groove 225. The end of the slide plate 226 away from the rotating shaft 223 is elastically connected to the inner wall of the movable groove 225 through a spring 227. One end of the spring 227 is fixedly connected to the outer wall of the slide plate 226, and the other end of the spring 227 is fixedly connected to the inner wall of the movable groove 225. The end of the slide plate 226 away from the rotating shaft 223 is fixedly connected There is a clip 228, the length of which is shorter than the difference between the depth of the movable groove 225 and the width of the slide 226. The length setting of the clip 228 ensures that the clip 228 can fully enter the interior of the movable groove 225. The clip 228 is used to clamp the diaphragm. The outer wall of the rotating shaft 223 is fixedly connected with a trapezoidal block 229. The trapezoidal block 229 is in the shape of a right-angled trapezoid, and the inclined surface of the trapezoidal block 229 is set on the side close to the slide 226 at the end away from the rotating shaft 223.

[0036] Reference Figure 2 、 Figure 4 and Figure 5 The interior and exterior of the connecting block 1 are jointly provided with an anti-falling component 3, and the anti-falling component 3 includes a mounting chamber 31, and the mounting chamber 31 is opened inside the connecting block 1. The inner wall of the connecting block 1 is slidably connected with a push rod 32, and the sliding direction of the push rod 32 is the front-back direction. The number of push rods 32 is consistent with the number of arc segments of the connecting groove 21. The outer wall of the push rod 32 is hinged with a connecting rod 33, and a plurality of connecting rods 33 are provided on the outside of each push rod 32. The end of the connecting rod 33 away from the push rod 32 is hinged with a pressing block 34, and the shape of the pressing block 34 is a cylinder connected to a hemisphere. The shape is formed, the outer wall of the push rod 32 passes through the inner wall of the connecting block 1, and the rear end of the push rod 32 is fixedly connected to the connecting plate 35. The inner wall of the connecting plate 35 passes through and is rotatably connected to the threaded rod 36. The area where the threaded rod 36 is connected to the connecting plate 35 is cylindrical, and the threaded area of ​​the threaded rod 36 is set in the front part of the area connected to the connecting plate 35. By setting the position of the threaded area of ​​the threaded rod 36, it is ensured that the threaded part of the threaded rod 36 does not affect the connection with the connecting plate 35. The outer wall of the threaded rod 36 passes through and is threadedly connected to the inner wall of the connecting block 1.

[0037] Working principle: When in use, the staff first moves the part of the rotating shaft 223 at the front end of the connecting block 1, so that the rotating shaft 223 drives the rotating drum 224 and the rotating sleeve 222 to move to the top edge position of the movable groove 221.

[0038] After moving to the appropriate position, the staff rotates the rotating shaft 223 while applying a rotational force to the rotating shaft 223, so that the rotating shaft 223 drives the rotating drum 224 to rotate. When it is rotated so that the movable groove 225 is exactly at the same horizontal position as the opening of the rotating sleeve 222, the rotating shaft 223 slides backward, thereby driving the trapezoidal block 229 to push the slide plate 226, so that the slide plate 226 drives the clamp 228 to move outward.

[0039] When the clamp 228 moves to the outside of the movable groove 225, the staff clamps the end of the diaphragm with the clamp 228. When the clamping is completed, the staff releases the rotating shaft 223, so that the slide 226 returns to the inside of the movable groove 225 under the elastic force of the spring 227.

[0040] After the slide plate 226 and the clamp 228 return to the inside of the movable groove 225, the staff manually fixes the rotating sleeve 222 in the area outside the connecting block 1, and then rotates the rotating shaft 223. Because the rotating sleeve 222 is manually fixed at this time, when the rotating shaft 223 rotates, only the rotating drum 224 and its internal structure rotate. Therefore, at this time, the diaphragm is driven by the rotating drum 224 to fill the gap between the rotating drum 224 and the rotating sleeve 222.

[0041] When the filling is completed, the staff controls the rotating shaft 223 so that the rotating shaft 223 moves along the direction of the movable groove 221, so that the diaphragm can move along the direction of the movable groove 221, so that the diaphragm can smoothly enter the connecting groove 21, so that its end can match the irregular shape of the connecting groove 21.

[0042] When the rotating shaft 223 moves to the lowermost end, the staff rotates the threaded rod 36, thereby increasing the area of ​​the threaded rod 36 entering the interior of the connecting block 1, thereby reducing the distance between the end of the threaded rod 36 and the connecting block 1, thereby reducing the distance between the connecting plate 35 and the connecting block 1, thereby causing the connecting plate 35 to drive the push rod 32 to move toward the front end.

[0043] When the push rod 32 moves, the connecting rod 33 changes from its original tilt to vertical. Therefore, the connecting rod 33 and the pressing block 34 are at the same horizontal position, so the pressing block 34 moves outward, so the pressing block 34 can press the diaphragm.

[0044] When the two diaphragms are connected in the above manner, the staff will inflate the interior of the diaphragm during use. Since part of the diaphragm is squeezed by the pressure block 34, the position of the diaphragm is not easily changed. Therefore, the remaining part can form a shape surrounding the pressure block 34 after expansion, thereby improving the connection effect.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
