[0041] Embodiment 2: Refer to Figures 1 to 5 , which is the first embodiment of the present utility model. This embodiment provides a riser with a quick-release protective ferrule, which can solve the problems that most of the risers with quick-release protective ferrules on the current market are assembled by bolts during assembly. The bolt connection is likely to cause the bolts to be soaked in the sea for a long time, resulting in the bolts slipping threads, and the assembly firmness effect of this method is poor, thus affecting the service life of the riser. A positioning and fixing mechanism 2, which includes a fixing block 201 and a fixing groove 207. The fixing block 201 is installed at the top of the first mounting ferrule 103. An installation groove 202 is opened on the side wall of the fixing block 201. Sliding rails 203 are installed at the top and bottom inside the installation groove 202. A slider 204 is arranged inside the sliding rails 203. A limiting block 205 is installed at one end of the slider 204 away from the sliding rails 203. A spring body 206 is installed on the side wall of one end inside the installation groove 202, and one end of the spring body 206 is fixedly connected to the side wall of the limiting block 205.

[0042] Fixing grooves 207 are opened at the bottom of the second mounting ferrule 108. A limiting groove 208 is opened on the side wall of one end inside the fixing groove 207, and the limiting groove 208 is engaged with the limiting block 205. Through the engagement of the limiting groove 208 and the limiting block 205, it is convenient to assemble the first mounting ferrule 103 and the second mounting ferrule 108 by engaging the limiting block 205 with the limiting groove 208.

[0043] The specific working principle is as follows: The sizes and structures of the first installation ferrule 103 and the first installation block 104 are the same as those of the second installation ferrule 108 and the second installation block 109. The fixing block 201 and the fixing groove 207 are engaged with each other. When the two riser conduit bodies 1 are assembled, the second installation ferrule 108 is used to squeeze the limiting block 205. Through the mutual cooperation of the slider 204 and the slide rail 203, the limiting block 205 is squeezed to drive the slider 204 to slide inside the slide rail 203 and squeeze the spring body 206 to deform, facilitating the entry of the limiting block 205 into the installation groove 202. Then, through the elastic recovery of the spring body 206, the limiting block 205 is driven to engage with the limiting groove 208, thus facilitating the assembly of the first installation ferrule 103 and the second installation ferrule 108. At the same time, the bolt rod 106 is respectively matched with the first through hole 105 and the second through hole 1091, and the bolt rod 106 is threadedly connected with the bolt sleeve 1061, thereby facilitating the assembly and fixation of the two riser conduit bodies 1 through the first installation ferrule 103 and the first installation block 104.
