When the 3 drive limit post 32 is to be disengaged from the latching portion 411 of the valve 4, the valve 4 can be opened to enable the unloading or loading. However, the patent accommodating groove 24 must be processed by the milling cutter on the hook body 2, and the control handle 3 must be mounted at the position of the accommodating groove 24, and the structure is configured. Or assembly, there are disadvantages of high cost and time-consuming labor. Under the trend of lower global production cost and lowering gross profit margin, the economic benefits of this kind of structural configuration are not high. The creator has succeeded in creating this creation in view of the above-mentioned missing items in the pre-existing patent case, and through the multi-party experimental design, in order to completely solve the problem of the existence of the application.
