The grinding reduction blocks are block structures with smooth corresponding surfaces and capable of bearing compressive stress, such as ceramic blocks, metal blocks made of stainless steel or copper, and the like. As a person skilled in the art, the corresponding surface is a surface that can slide relatively when tripped: the lower end face of the third grinding reduction block, the upper end face of the fourth grinding reduction block, the upper end face of the first grinding reduction block and the lower end face of the second grinding reduction block.

when no compressed gas exists in the body of the air cylinder, the piston ring keeps the cross rod section 9 in a state of providing supporting force for the carriage connecting plate 3 under the acting force of the spring;
when compressed gas is filled into the cylinder body of the cylinder, the piston ring overcomes the elasticity of the spring, and drives the cross rod section 9 to rotate to be parallel to the through hole 6, so that the connection relation between the connecting buckle 5 and the carriage connecting plate 3 is removed, and the carriage connecting plate 3 falls down under the gravity. The power hanging piece is low in cost and beneficial to safety of the power hanging piece in use.
As a specific implementation form of the locking member 14, the locking member 14 is a nut screwed on the vertical rod section 8, and the number of the nuts is more than one. In this scheme, connect the nut on the montant section 8 that stretches out for connecting plate seat 4 upside, when being in the terminal surface of downside nut and the terminal surface contact of connecting plate seat 4, the support of connecting plate seat 4 to connector link 5 is passed through the nut and is passed on connector link 5. Because the number of the nuts is more than one, the nuts can be mutually locked to effectively avoid the connection failure of the locking piece 14 and the vertical rod section 8, and meanwhile, the number of the sheared threads between the nuts and the connecting buckle 5 can be increased by more than one nut, so that the bearing capacity of the power pendant is improved.
