The invention provides a block-to-stop transmission device; the block-to-stop transmission device comprises a drive chain wheel and a transmission chain wheel; the drive chain wheel and the transmission chain wheel are concurrently circled by an enclosed chain, so as to enable the drive chain wheel and the transmission chain wheel to be driven by the chain; a control device of the drive chain wheel is arranged in a never changed position with respect to the rotation axis of the drive chain wheel; a switch of the control device always directly or indirectly pushes against the chain via an elastic device, thus the position of the switch with respect to the control device can be changed when the chain is not wrapped on the drive chain wheel, or the portion of chain on the transmission chain wheel is loosened or tightened, thereby changing the work state of the switch. The control device of the block-to-stop transmission device is matched with the chain by using the elastic device and a micro switch, so as to conveniently and effectively identify whether the output end of the transmission mechanism is blocked, and timely control the drive chain wheel to stop the power output by controlling the triggering of the switch, thereby achieving the block-to-stop function; additionally, a certain motion process exists when the chain changes from the tightened position to the loosened limit position, thus the whole mechanism has a margin for sufficient buffering, so as to effectively prevent the mechanical parts from irreversible deformation caused by emergent forward braking of the mechanical parts.
