Embodiment Construction

[0012] Examples, see Figure 1 to Figure 3 Shown: double end tackle, including frame 10. The upper side of the frame 10 is provided with an upper pulley 20 , and the lower side of the outer side is provided with a lower pulley 30 . An opening 11 for passing cables 100 is opened on the left side panel of the frame 10 . The outer card of the frame 10 is provided with a "U"-shaped baffle 40 . That is, the baffle plate 40 has a left side plate and a right side plate, and the upper end of the left side plate and the upper end of the right side plate are connected through the upper side plate. The left side of the baffle 40 is located on the left side of the left side of the frame 10 , and the left side of the baffle 40 matches the opening 11 . That is, the left side plate of the baffle plate 40 can open the opening 11 and close the opening 11 . The right side of the baffle 40 is located on the right side of the right side of the frame 10 , and a pull ring 50 is connected to the...
