And thread it, so when the output shaft 202 is rotated, the clamping portion 203 is lift.
[0033] The locking mechanism 30 includes a housing 301 that is fixed to one of the column 114, and the locking mechanism 30 further includes a mount 319 fixed to the back of the outer casing 301, and the mounting body 319 is secured between the outer casing 301. The mounting body 319 is provided with two semicircular positioning ring 320, and the positioning ring 320 is fixed to the outer side of one of the column 114; the outer casing 301 is provided with a spindle 302 and a worm 303, a spindle. 302 and worm 303 are rotated within the outer casing 301, wherein the main shaft 302 is fixed to the first cone gear 304 and the second cone 305, and the first tapered gear 304 is engaged with the worm 303, one end of the worm 303 is connected. There is a drive lever 306, and the drive rod 306 is fixed between the drive rod 303, and the transmission rod 306 is remote from one end of the worm 303 to the outer casing 301 and solids a strip 307, and the strip 307 runs through the bar. The width of the bore 308, the width of the strip hole 308 is the same as the diameter of the extension rod 2034, and the extension rod 2034 is inserted into the strip hole 308, and therefore, when the grip portion 203 lifes down, the worm 303 is rotated, and the worm 303 is rotated. The rotation will indirectly drive the spindle 302 to rotate.
[0034] The inner portion of the outer casing 301 is provided with a driven shaft 309 in a direction perpendicular to the main shaft 302, and a third cone 310 is fixed to the driven shaft 309, and the third cone gear 310 is engaged with the second cone 305, and One end of the moving shaft 309 is rotated in the inner wall of the outer casing 301, and the other end of the driven shaft 309 is penetrated out, and the outer wall of the outer casing 301 is fastened to the stop shaft 311, the stop shaft sleeve 311 and the outer casing.
