The screwing nut is fixedly arranged on the adjusting screw rod, so that the adjusting screw rod can be conveniently screwed, the positioning ratchet wheel is arranged on the adjusting screw rod, the pawl is arranged, when the adjusting screw rod is rotated, the positioning ratchet wheel synchronously rotates and is in one-way rotation fit with the pawl, after the adjusting screw rod is adjusted, the pawl locks the positioning ratchet wheel reversely, the positioning ratchet wheel is prevented from reversely rotating, and the tightening state of the driven chain is maintained. The limiting mechanism comprises a chain connecting plate, the chain connecting plate comprises a fixing part and a connecting part, the fixing part is provided with a plurality of connecting holes, the connecting holes are positioned on the same straight line and are respectively in one-to-one correspondence with and inserted with a plurality of rolling shafts of the driven chain, so that the fixing part is fixed, the driven chain is supported tightly, the fixing part can not move or rotate unnecessarily, the connecting part is further arranged to be a rectangular strip by arranging the connecting part of the connecting part and is arranged along the transmission direction of the driven chain and outside the driven chain, when the driven chain drives the connecting part to move through the fixing part, the connecting part is always parallel to the driven chain, the connecting part is further provided with a plurality of limiting auxiliary wheels, the circle centers of the limiting auxiliary wheels are positioned on the same straight line and are parallel to the transmission direction of the driven chain, and the rotating plane of the limiting auxiliary wheels, when the two connecting pieces are simultaneously connected with a moving piece, if the connecting piece is horizontally arranged, the connecting piece is subjected to pulling force generated by gravity from the vertical direction, and the moving piece has a volume, so that the gravity of a part of the moving piece away from the connecting piece not only generates pulling force in the vertical direction but also generates partial pulling force in the horizontal direction, spacing auxiliary wheel can offset this partial power this moment, supports the protection to driven chain, prevents that driven chain from taking place deformation. Meanwhile, the lower end face of the limiting auxiliary wheel is in contact with the rail or the sliding groove due to the pulling force in the vertical direction, and the driven chain is tightly supported, so that the moving range of the limiting auxiliary wheel can be limited, the lower end face of the limiting auxiliary wheel is prevented from being in contact with the rail or the sliding groove and tightly supported, and the limiting auxiliary wheel rolls smoothly all the time. The transmission speed of the second transmission mechanism can be adjusted by arranging the driving gear and the driven gear which are meshed with each other and adjusting the transmission ratio of the driving gear and the driven gear, and the chain transmission mechanism formed by the driving chain wheel, the driven chain wheel and the driven chain utilizes the characteristics of small occupied space and convenient movement of the chain transmission mechanism to conveniently adjust the setting position of the driven shaft.
