description One end of the fixed pulley is connected with a left arm and a right arm, one ends of an upper support and the left arm and the right arm are clamped with quick-release pins, one ends of the upper support and the left arm and the right arm, which are far away from the quick-release pins, are clamped with connecting pins, and one ends of the upper support and the left arm and the right arm, which are close to the connecting pins, are clamped with large-lug pins. The two ends of the fixed pulley are limited and supported through the left arm and the right arm, normal use of the fixed pulley is guaranteed, the upper support is limited and quickly disassembled through the quick-release pin, the connecting pin and the large-lug pin, and the upper support or the fixed pulley can be quickly opened when needing to be replaced. The hoisting ring pin shaft, the mounting hoisting ring and the spring pin are matched with one another, so that the hoisting ring can be conveniently and quickly combined with an external hois
