The riser is mainly used for rising on steep terrain and is matched with a safety belt and a main rope for use when a hole is explored for rising or protection. Furthermore, risers are also an important component of the lifting systems (hauging systems), often replacing the "paw ropes" (also called "chicken paw ropes", i.e. "Prusik"). The device is a core instrument for dragging a heavy object when a fire fighting and rescuing mechanism deals with an accident, and plays a role of repeatedly pulling and lifting in a pulling and lifting system.

Furthermore, a limiting member (Rope Wrench Stop)16 is disposed at one side of the pivot portion 13, and the limiting member 16 is used for limiting the Rope Wrench 2 from swinging downward too much. In the drawings, the handle 12, the pivotal portion 13 and the fastening portion 14 are integrally formed.

The rope wrench 2 is pivotally connected to the pivot portion 13 of the rod 11, and the rope wrench 2 includes two side plates 21, a bolt (Slic Pin)22, a pulley 23 and a pivot shaft 24. The two side plates 21 are sequentially provided with two corresponding first connection holes 211, second connection holes 212 and third connection holes 213. The pin 22 is assembled in the first holes 211, and when the pin 22 passes through two of the first holes 211, a pin 221 is inserted into a pin hole 222 at one end of the pin 22, so that the pin 22 is not loosened. In addition, the pulley 23 is pivotally connected to two of the second connecting holes 212, and when the bolt 22 and the pulley 23 are assembled to the two side plates 21, a passage 25 for a rope (not shown) to pass through is formed between the bolt 22 and the pulley 23. After the pivot shaft 24 passes through the two third connection holes 213 of the two side plates 21 and the pivot hole 131 of the pivot portion 13 to be assembled with a shaft cap 241, the rope wrench 2 is pivoted on the pivot portion 13 of the rod 11. In the present illustration, the peg 22 is a self-locking implantable peg.

The pulley block 3 is assembled on the fixing portion 14 of the rod 11, and the pulley block 3 includes: two folding plates 31, a pulley 32 and an axle 33.
