[0025] Reference Figure 2 and Figure 3 The front and back sides of the connecting plate 206 are movably connected with a first limiting ring 209. The inner cavity of the first limiting ring 209 is fixedly connected to the surface of the rotating shaft 208. Through the setting of the first limiting ring 209, the rotation of the connecting plate 206 is limited, thereby avoiding the displacement of the connecting plate 206 during rotation.

[0026] Reference Figure 4 、 Figure 5 and Figure 6 The top of the connecting plate 206 is provided with a tightening mechanism 3, and the tightening mechanism 3 includes a mounting plate 301, the bottom of the mounting plate 301 is movably connected to the top of the connecting plate 206, the inner cavity of the mounting plate 301 is movably connected to the movable plate 303, and the bottom of the inner cavity of the movable plate 303 is movably connected to the second support column 307, the front and back sides of the second support column 307 are fixedly connected to the inner wall of the connecting plate 206, and the left side of the mounting plate 301 is fixedly connected to the plug column 305, the surface of the plug column 305 is movably connected to the inner cavity of the fixed column 207, the interior of the plug column 305 is fixedly connected to the rotating column 308, and the surface of the rotating column 308 is movably connected to the fixed plate 310. The setting of the second support column 307 supports the bottom of the movable plate 303, so that the movable plate 303 is stable when rotating inside the connecting plate 206, and the setting of the rotating column 308 fixes the left side of the fixed plate 310 so that the fixed plate 310 can rotate inside the plug column 305.

[0027] Reference Figure 4 and Figure 5 The inner cavity of the movable plate 303 is provided with a slide groove 306, and the inner cavity of the slide groove 306 is movably connected to the connecting rod 302. The front and back sides of the connecting rod 302 are fixedly connected to the inner cavity of the mounting plate 301. Through the setting of the slide groove 306, the connecting rod 302 can move inside the movable plate 303 and guide the moving position of the connecting rod 302 at the same time.

[0028] Reference Figure 5 and Figure 6 The front and back sides of the fixed plate 310 are movably connected with a second limiting ring 309. The inner cavity of the second limiting ring 309 is fixedly connected to the surface of the rotating column 308. Through the setting of the second limiting ring 309, the rotation of the fixed plate 310 is limited to prevent the fixed plate 310 from deflecting during rotation.

[0029] Reference Figure 6 The bottom of the fixing plate 310 is fixedly connected to a third fixing block 311, and the bottom of the third fixing block 311 is fixedly connected to a spring 312. One end of the spring 312 is fixedly connected to a fourth fixing block 313. The bottom of the fourth fixing block 313 is fixedly connected to the inner wall of the plug column 305. Through the arrangement of the third fixing block 311 and the fourth fixing block 313, the stability between the spring 312 and the fixing plate 310 is improved, and the disconnection between the spring 312 and the fixing plate 310 is avoided. Through the arrangement of the spring 312, when the fixing plate 310 rotates, the spring 312 is deformed, and when the fixing plate 310 recovers its deformation, the fixing plate 310 is driven to quickly reset.

[0030] Reference Figure 4 The top of the movable plate 303 is fixedly connected with a grip column 304. The surface of the grip column 304 is provided with a rectangular groove, and the number of the rectangular grooves is multiple. Through the setting of the grip column 304, the contact area between the operator's hand and the movable plate 303 is increased, thereby facilitating the rotation of the movable plate 303. At the same time, the grip column 304 is provided with multiple rectangular grooves, which further facilitates the rotation of the grip column 304.

[0031] Working principle: The operator holds the ceramic fiber insulation cotton 201 and wraps the ceramic fiber insulation cotton 201 to the surface of the exhaust pipe 1. Then, the operator pulls apart the first semicircular connecting block 202 and the second semicircular connecting block 203. At the same time, the bottom of the second semicircular connecting block 203 rotates around the surface of the first support column 210. Then, the inner cavity of the first semicircular connecting block 202 and the second semicircular connecting block 203 is attached to the surface of the ceramic fiber insulation cotton 201 for wrapping. The operator rotates the connecting plate 206 by hand. At the same time, the right side of the connecting plate 206 is enclosed. The surface of the rotating shaft 208 is rotated. When the connecting plate 206 is rotated and sleeved on the surface of the fixing column 207, the first semicircular connecting block 202 and the second semicircular connecting block 203 are fixed. At the same time, the ceramic fiber insulation cotton 201 is fixed to the surface of the exhaust pipe 1 for heat insulation. Then, the grip column 304 is pulled by hand to drive the movable plate 303 to move to the left. The bottom of the movable plate 303 is supported by the second support column 307, so that the bottom of the movable plate 303 rotates around the surface of the second support column 307. The movement of the connecting rod 302 makes it move inside the slide groove 306. When the connecting rod 302 moves the top of the inner cavity of the slide groove 306, it drives the mounting plate 301 to move to the left on the top of the connecting plate 206. The mounting plate 301 drives the plug post 305 to move, and the plug post 305 drives the fixing plate 310 to move. When the fixing plate 310 moves to the inside of the fixing column 207, the surface of the fixing plate 310 contacts the inner wall of the fixing column 207, and the fixing plate 310 is squeezed, so that the fixing plate 310 rotates around the surface of the rotating column 308. The rotation causes the spring 312 to be deformed and move downward under the force. When the plug post 305 drives the fixing plate 310 to move through the interior of the fixing post 207, the spring 312 loses its compression force and recovers its deformation to push the fixing plate 310 to rotate upward around the surface of the rotating post 308, so that one end of the fixing plate 310 is in contact with the surface of the fixing post 207 to tighten the first semicircular connecting block 202 and the second semicircular connecting block 203, so that the ceramic fiber insulation cotton 201 can be more closely attached to the surface of the exhaust pipe 1 for insulation, thereby preventing the exhaust pipe from heating up and causing burns to the rider.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
