A fixing mechanism is set on the fixed frame 4 for replacing the drive ring 6. Two guide wheels 20 are rotatably arranged between the fixed frames 4, and the guide wheels 20 are respectively set on both sides of the drive column 5.

[0058] The positioning mechanism includes a positioning through groove 8, a first positioning groove 9, a first positioning block 10, a first cavity, a positioning port 11, a positioning ring 12, a second positioning block 13, and a driving mechanism. The positioning through groove 8 is formed on the driving column 5. Multiple first positioning grooves 9 are formed on the side walls of the first positioning grooves 9. The first positioning block 10 is fixedly set on the inner wall of the driving column 5 corresponding to the positioning through groove 8, and the first positioning block 10 is slidably connected to the side wall of the positioning through groove 8. The first cavity is annular and is formed inside the driving ring 6. The positioning port 11 is formed on the inner wall of the first cavity corresponding to the first positioning groove 9. The positioning ring 12 is rotatably set in the first cavity. The second positioning block 13 is fixedly set on the inner wall of the first cavity corresponding to the positioning port 11. On the inner wall of the positioning ring 12, a drive mechanism is set on the drive ring 6 to control the rotation of the positioning ring 12. The drive mechanism includes a first support groove, a support opening, a support ring 14, a second support groove, a support column 15, and a limiting mechanism. The first support groove is opened on the side wall of the drive ring 6, and the support opening is arc-shaped and is opened between the first support groove and the first cavity. The support ring 14 is set in the first support groove, and a handwheel is fixedly set on the outer wall of the support ring 14. The second support groove is opened on the positioning ring 12 corresponding to the support opening. The support column 15 is slidably set in the second support groove, and the end of the support column 15 away from the positioning ring 12 is fixedly connected to the support ring 14. The limiting mechanism is set in the first support groove to limit the rotation angle of the support ring 14.

[0059] Specifically, the operator pushes the drive ring 6 to move on the drive column 5. When it moves to the appropriate position, the operator turns the handwheel, which drives the support column 15 to rotate through the support ring 14. Then, through the cooperation between the support column 15 and the second support groove, the positioning ring 12 and the second positioning block 13 are rotated, so that the second positioning block 13 can extend into the first positioning groove 9.

The limiting spring 17 is fitted on the support column 15, and both ends of the limiting spring 17 are fixedly connected to the bottom of the first support groove and the support ring 14, respectively.

[0061] Specifically, under the action of the limiting spring 17, the support ring 14 will fit against the bottom of the first support groove, thereby causing the limiting block to extend into the limiting groove 16. Then, the limiting block and the limiting groove 16 cooperate to limit the support ring 14, thereby preventing the drive ring 6 from loosening during use.

[0062] The fixing mechanism includes a fixing port, a fixing ring, and a fixing plate 18. The fixing port is opened on the side wall of the fixing frame 4 corresponding to the drive column 5.

The fixing plate 18 and the fixing frame 4 are provided with fixing bolts 19 through bolt cooperation.

[0063] In use, after the operator puts the drive ring 6 onto the drive column 5 through the fixing port, the operator inserts the fixing ring into the fixing port, so that the drive column 5 extends into the fixing ring. At the same time, the fixing plate 18 and the fixing frame 4 are fixed by the fixing bolt 19, which can limit the drive column 5 and prevent the drive column 5 from tilting.

[0064] In this embodiment, during use, after the operator installs the drive ring 6 onto the drive column 5 through the fixing port, the operator inserts the fixing ring into the fixing port, allowing the drive column 5 to extend into the fixing ring. Simultaneously, the fixing plate 18 is fixed to the fixing frame 4 using the fixing bolts 19, thus limiting the drive column 5 and preventing it from tilting. The operator then pushes the drive ring 6 to move it on the drive column 5. When it reaches the appropriate position, the operator pulls the handwheel, causing the limiting block to disengage from the limiting groove 16. Then, rotating the handwheel drives the support column 1 through the support ring 14. 5. Rotation causes the positioning ring 12 and the second positioning block 13 to rotate through the cooperation of the support column 15 and the second support groove. This allows the second positioning block 13 to extend into the first positioning groove 9. Simultaneously, the cooperation between the second positioning block 13 and the first positioning groove 9 achieves the installation and positioning of the drive ring 6. Afterward, the operator releases the handwheel, and under the action of the limit spring 17, the support ring 14 will fit against the bottom of the first support groove, thereby causing the limit block to extend into the limit groove 16. The cooperation between the limit block and the limit groove 16 achieves the limitation of the support ring 14, thus preventing the drive ring 6 from loosening during use.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
