    BE2019 / 5040 to achieve a more stable abseiling effect.
    The friction sections 374 of each reduction mechanism 370 are preferably provided in a number of two, the two friction sections 374 being arranged at a distance from one another and connected to one another by a spring 378. At a
    High-speed rotation of the friction wheel 373, the two friction sections 374 each move in a direction facing away from the friction wheel 373; if the rotational speed of the friction wheel 373 is too high, the centrifugal force of the friction section 374 becomes too great, so that the friction section 374 comes into close contact with the side wall plate 355 and it is easier for locking to occur, while no friction force between the friction section 374 and the side wall plate 355 is produced; therefore a spring 378 is arranged between the two friction sections 374; more specifically, two springs 378 are interposed between the two friction portions 374, each end of each spring 378 being connected to a friction portion 374, and if the contact between the friction portion 374 and the side wall plate 355 is too close, the springs 378 will cause a tensile force exerted on the friction portion 374 to retract the friction portion 374 to maintain a proper position between the friction portion 374 and the side wall plate 355 so that they can rub against each other to achieve braking.

This increases the frictional force between the friction portion and the side wall plate 355 of the end cap 353 and improves the abseiling effect to achieve safe stable abseiling.
    Preferably, the friction portion 374 includes a friction block 375 and a friction washer 376, wherein the friction block 375 is located in the mounting groove 377 and is outside of the friction wheel 373, and the friction washer 376 is located outside of the friction block 375 and is located within the side wall plate 355.

    BE2019 / 5040
    Friction blocks 375 in a direction away from the friction wheel 373 have a better effect; with the arrangement of the asbestos friction disk, the frictional force between the friction disk 376 and the side wall plate 355 can be increased in order to further improve the abseiling stability of the abseiling device 300 for fleeing from a high position; at the same time, the friction disc has better temperature resistance and can withstand the high temperature generated by the friction force, which extends the life of the friction disc 376.
    Preferably, a mounting ring 379 is disposed on both ends of the friction block 375 of each friction section 374, both ends of the spring 378 being installed in the mounting ring 379 of the two friction blocks 375, respectively, to install the spring 378 so that the spring force between the two friction blocks 375 is distributed more evenly. In the present embodiment, the friction washer 376 and the friction block 375 are connected to each other by a screw, but they can also be connected to each other by gluing; so they can be combined with each other to make disassembly and replacement easier.
