The outer side of the positioning slide bar 204 is slidably sleeved with a movable clamping piece 205. The outer side of the clamping screw 203 is welded with a clamping piece 206. There are two clamping pieces 206, and the two clamping pieces 206 are sleeved on the outer side of the clamping screw 203 at both sides of the movable clamping piece 205, which is convenient for pushing the movable clamping piece 205. An activity groove is opened at the corresponding position of the inner side of the movable clamping piece 205 and the positioning slide bar 204. The movable clamping piece 205 is slidably connected with the positioning slide bar 204 through the activity groove, which is beneficial for the movable clamping piece 205 to slide in the same direction;

[0032] One end of the clamping screw 203 is welded with a turntable 207. The top end of the rotating rod 1 is welded with a non-slip piece 208. The bottom of the rotating rod 1 is provided with a base 209. An installation groove is opened at the corresponding position of the inner side of the base 209 and the support bearing 210. The support bearing 210 is embedded in the inner side of the base 209 through the installation groove, which is convenient for welding multiple support legs. The support bearing 210 is installed inside the base 209. The support leg mounting plate 211 is rotatably installed inside the support bearing 210. A cylinder seat groove 212 is opened inside the support leg mounting plate 211.

[0033] The lifting component 3 is installed at the top end of the base 209;

[0034] The lifting component 3 includes a limiting rod 301, an installation cylinder 302, a limiting groove cylinder 303, a lifting plate 304, a lifting cylinder 305 and a movable bearing 306;

[0035] The limiting rod 301 is welded at the top end of the base 209. The installation cylinder 302 is installed at a position on one side of the limiting rod 301 of the base 209. The outer side of the limiting rod 301 is slidably sleeved with the limiting groove cylinder 303. One side end face of the limiting groove cylinder 303 is welded with the lifting plate 304. The lifting cylinder 305 is installed at the top end of the installation cylinder 302. The movable bearing 306 is embedded inside the lifting plate 304. The rotating rod 1 is installed inside the movable bearing 306. The telescopic end of the lifting cylinder 305 is connected with the lifting plate 304. The input end of the lifting cylinder 305 is electrically connected with the output end of an external power source, which is convenient for different specifications.

[0036] Working principle and usage process of the present utility model: First, before welding, the operator places the office chair leg to be welded on the top of the support leg mounting plate 211, arranges it at equal angles along the outer edge of the cylinder seat groove 212, and then sleeves the cylinder seat to be welded at the outer side position of the fixed clamping piece 201 and the movable clamping piece 205. Subsequently, the operator can rotate the turntable 207 to drive the clamping screw 203 to move in the inner side of the clamping sleeve 202 in the opposite direction of the fixed clamping piece 201, so as to drive the movable clamping piece 205 to slide on the outer side of the positioning slide bar 204 through the clamping piece 206, and clamp and fix the cylinder seat through the movable clamping piece 205 and the fixed clamping piece 201. Then, control the lifting cylinder 305 to move downward, so as to move the cylinder seat to the inner side of the cylinder seat groove 212. At this time, weld one of the legs to the cylinder seat, and then rotate this leg, which can drive the support leg mounting plate 211 to rotate in the inner side of the support bearing 210. Subsequently, rotate the leg that has not been welded to the welding position, and then weld the other legs to the cylinder seat, so as to ensure that the relative positions of the cylinder seat and the legs are fixed. And because the movable clamping piece 205 can slide, it can be applied to cylinder seats of different specifications, ensuring that cylinder seats and legs of different specifications can be welded accurately and quickly during welding, further ensuring the manufacturing efficiency and quality of office chairs;

[0037] Next, when welding cylinder seats of different lengths, the lifting cylinder 305 can be lifted and lowered, which can not only adapt to the welding of cylinder seats of different lengths, but also finely control the welding points between the legs and the cylinder seats during welding, ensuring that the welding positions of the same batch are fixed and unified. And by sliding the limit groove cylinder 303 on the outer side of the limit rod 301, it can ensure that the lifting plate 304 slides at the same horizontal position, further ensuring the identity of the welding points, thereby enhancing the support strength of office chairs.
