[0014] (Three) beneficial effects

[0015] 1. This utility model, through the arrangement of rotating rods, gears, locking blocks, transmission belts, sector teeth, guide teeth, and welding equipment, allows one rotating rod to rotate when the motor drives it, which in turn drives one gear to rotate. This causes the meshing gear to drive the other rotating rod to rotate in the opposite direction, resulting in both rotating rods driving the turntable to rotate in the opposite direction. This achieves the purpose of multiple locking blocks on both sides conveying the two chain segments closer together. Furthermore, when the locking blocks engage with the slots within the roller chain, they ensure the stability of the roller chain, indirectly achieving a positioning effect. Simultaneously, one rotating rod... When rotating, the transmission belt that drives the shaft to rotate, causing the shaft to rotate the sector teeth. When the shaft rotates the sector teeth, the guide teeth that mesh with the sector teeth move the welding equipment upward, bringing the two roller chains closer to each other to a suitable welding position. At the same time, the welding equipment also rises to a suitable height to weld the two roller chains. Thus, this device can integrate the welding and positioning of the roller chains, preventing the two roller chains from being misaligned during the welding process and affecting the welding accuracy. It also eliminates the need for a separate positioning device to fix the two roller chains, thereby improving the welding efficiency between the roller chains.

[0016] 2. This utility model, through the setting of an adjusting rod and a spring, utilizes the elastic cooperation between the adjusting rod and the spring to enable the locking block to have an adaptive adjustment function. This allows the locking block to smoothly engage in the slot of the roller chain and stably transport the roller chain when it contacts the roller chain, even if the position of the empty slot of the roller chain does not correspond to the position of multiple locking blocks.
