[0027] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4The top of the limiting member 3 is fixedly connected to the limiting component 4 on the outside of the push rod 301. The limiting component 4 consists of an adjusting frame 401, a bidirectional screw 402, a rotating handle 403, and two sets of plug-in blocks 404. A set of locking holes 4011 is provided on both sides of the adjusting frame 401 at positions corresponding to the plug holes 3011. A movable groove 4012 is provided inside the adjusting frame 401. The bidirectional screw 402 is rotatably connected inside the movable groove 4012. One end of the bidirectional screw 402 is fixedly connected to the rotating handle 403 on the outside of the adjusting frame 401. Two sets of plug-in blocks 404 are fixedly connected to a plug rod 4041 on the side of the two sets of plug-in blocks 404 that are far apart and at the position corresponding to the locking hole 4011. The plug-in blocks 404 and the bidirectional screw 402 are provided with threaded adjustment holes 4042 at the corresponding positions. Turning the handle 403 drives the bidirectional screw 402 to rotate, so that the two sets of plug-in blocks 404 are threadedly connected to the bidirectional screw 402 through the threaded adjustment holes 4042 for spacing adjustment. The plug rod 4041 is inserted into the locking hole 4011 through the corresponding insertion hole 3011 to limit and fix the push rod 301.

The outer side of the lead screw 603 is threadedly connected to the top of the limiting member 3 with a limiting nut 6031. When the cross-sectional dimensions of the pier column are adjusted by sliding the pier column mold 5 up and down, the slider 602 is driven to slide and be synchronously adjusted through the limiting slider 6021 and the guide groove 6012. After the adjustment is completed, the limiting nut 6031 is threadedly connected to the lead screw 603 at the top of the limiting member 3 to limit and fix the slider 602, thereby improving the stability of the mold adjustment.

[0030] The working process of this utility model is as follows: First, pulling the pull rod 302 drives the pier column horizontal mold 5 through two sets of push rods 301 to slide and connect with the guide slider 501 and the limiting slide groove 102. The pier column cross section is adjusted up and down according to the requirements. When the pier column horizontal mold 5 slides up and down to adjust the pier column cross section size, the sliding part 602 is driven to slide and connect with the guide groove 6012 through the limiting slider 6021 for synchronous adjustment. After the adjustment is completed, the rotating handle 403 is turned to drive the bidirectional screw 402 to rotate, so that the two sets of plug blocks 404 are threadedly connected with the bidirectional screw 402 through the threaded adjustment hole 4042 for spacing adjustment. The plug rod 4041 is inserted into the corresponding plug hole 3011 and embedded in the card hole 4011 to limit and fix the push rod 301 and the pier column horizontal mold 5. The limiting nut 6031 is threadedly connected to the screw 603 at the top of the limiting part 3 to limit and fix the sliding part 602, thereby improving the stability of the mold structure.
