The invention discloses a fixed pulley. The fixed pulley comprises a fixed frame, a pulley mechanism and a locking mechanism, wherein the fixed frame comprises a hollow sleeve and a U-shaped clamping groove, the U-shaped clamping groove is fixedly connected to one end part of the hollow sleeve, and a U-shaped cross section of the U-shaped clamping groove is parallel to the axis of the hollow sleeve; the pulley mechanism comprises a pulley support and a pulley, and the pulley is movably connected with the pulley support; the locking mechanism comprises two locking rods, a pressure plate and two locking sleeves, each locking rod is respectively fixed on each supporting rod, two end parts of the pressure plate in the length direction are respectively provided with a through hole or a through groove, the pressure plate sleeves the two locking rods by utilizing the through hole or the through groove, and the pressure plate is arranged between the locking sleeve and the fixed end of the locking rod. By adopting the fixed pulley, the abrasion of a transmission belt is small, the manpower cost is remarkably saved, the operation safety is high, the structure is stable, and the use is convenient.
