[0027] The sliding wheel 107 is installed in the middle part of the support frame 101 through the shaft, that is, the rope rolls on the sliding wheel 107, and the object moves up and down. The sliding wheel 107 is symmetrically installed with a rotating shaft in the circumference, and a limiting cylinder 108 is sleeved on the rotating shaft. The limiting cylinder 108 rolls on the rotating shaft, that is, the limiting cylinder 108 limits the axial direction of the rope to ensure that the rope can slide along the middle part of the sliding wheel 107.
[0028] like Figure 2 , 3As shown, a through hole 201 is provided through the top of the clamping shaft 103, and two through holes 201 are provided, one of which has the same orientation as the hook body 102, and the two through holes 201 are vertically distributed and pass through the center of the same circle, and a fastening bolt 202 passing through the two side walls of the support frame 101 is installed on the through hole 201, and one end of the fastening bolt 202 is locked by a nut, that is, the clamping shaft 103 is rotated so that the two through holes 201 respectively support the plates of the frame 101 horizontally, and the orientation of the hook body 102 is fixed by the fastening bolt 202.
[0029] like Figure 1 , 2 As shown, a U-shaped support plate 203 is also extended from the top of the support frame 101, and a lifting ring 204 is fixedly installed on the top of the U-shaped support plate 203, that is, the parts can be moved individually through the lifting ring 204 on the top of the U-shaped support plate 203; a hand pull ring 205 is extended from the side wall of the lock tongue 105, that is, the hand pull ring 205 can assist the staff to remove the items hung on the hook body 102, and the lock tongue 105 is driven to rotate around the fixed axis 104 through the hand pull ring 205 to remove the hanging objects on the hook body 102; the clamping shaft 103 passes through the bottom plate of the support frame 101 and a groove is opened inside, and the clamping shaft 103 is rotatably clamped in the groove, that is, the groove can ensure that the clamping shaft 103 is clamped and rotates at the same time.
