[0040] The guide rail 2 is fixed on the clamping block 1, and the fall arrester is slidably connected to the guide rail 2 and can move along the guide rail 2 to the steering block 7;

[0041] When in use, the personnel moves the anti-fall device to the steering block 7 and corresponds to the displacement of the handle 31. Then the personnel pulls the handle 31 and hangs the handle 31 on the hanging block. At this time, the handle 31 pulls down the anti-fall device through the hanging block, so that the displacement of the anti-fall device is limited.

[0045] The lower end of the middle tube 33 is provided with an inclined groove 39, and the plug-in plate 302 is located in the inclined groove 39 and contacts the inclined side surface of the inclined groove 39. When the inclined groove 39 moves upward, the plug-in plate 302 gradually shrinks and separates from the limiting plate 10.

[0046] The outer cylinder 306 is provided with a limiting assembly for limiting the upward movement of the intermediate cylinder 33, and the pressurizing assembly can push the limiting assembly to no longer limit the intermediate cylinder 33;

[0047] The hardness of the spring connecting the intermediate cylinder 33 and the outer cylinder 306 is greater than the hardness of the spring between the intermediate cylinder 33 and the piston 37, so that when the spring between the piston 37 and the intermediate cylinder 33 is squeezed and the exhaust control assembly is connected to the outside, the intermediate cylinder 33 can be elastically reset;

[0048] When in use, the personnel hangs the handle 31 on the hanging plate 5, the pressurizing assembly moves up and drives the intermediate cylinder 33 to move up, at this time the inclined groove 39 moves up, so that the plug-in plate 302 is separated from the limiting plate 10, at this time the outer cylinder 306 can be displaced along the displacement groove 9, the personnel turns the steering wheel 4, the steering wheel 4 drives the outer cylinder 306 to be displaced, during the displacement process, the exhaust control assembly gradually enters the arc groove 82 and the pull-down groove, the exhaust control assembly gradually opens and closes, and when opened, it is used to discharge the gas in the pressurizing assembly, so that the intermediate cylinder 33 can move down, and enter the limiting plate 10 when the outer cylinder 306 moves to the other end of the displacement groove 9, under the action of the intermediate cylinder 33, the plug-in plate 302 moves outward along the inclined groove 39 until it is inserted into the limiting plate 10, the limiting plate 10 limits the intermediate cylinder 33, and the personnel removes the handle 31 from the hanging plate 5.

[0049] In this embodiment, the pressurizing assembly includes a piston 37 sealed and plugged into the inner wall of the intermediate cylinder 33, a connecting rod 35 connected to the piston 37, and a connecting plate 32 connected to the connecting rod 35. The piston 37 is elastically connected to the intermediate cylinder 33 through a spring, and a one-way valve 303 is sealed and fixed on the piston 37 so that the piston 37 can be elastically reset.

[0050] A pressurized chamber 331 is provided at the lower end of the intermediate cylinder 33. The pressurized chamber 331 and the bottom wall inside the intermediate cylinder 33 are both connected to the exhaust control assembly. An unlocking rod 333 is sealed and connected inside the pressurized chamber 331. A sealing sleeve 34 is sealed and fixed on the upper side of the interior of the intermediate cylinder 33. The sealing sleeve 34 is in sealing contact with the connecting rod 35 and a circular protrusion is provided at the lower end of the sealing sleeve 34. A connecting passage 304 connected to the pressurized chamber 331 is provided in the intermediate cylinder 33. The connecting passage 304 is connected to the inner wall of the intermediate cylinder 33 on one side of the circular protrusion. When the piston 37 moves upward, the unlocking rod 333 can push the limiting assembly to no longer limit the intermediate cylinder 33.

[0051] When in use, a person pulls the connection plate 32 upward through the handle 31, and the connection plate 32 drives the piston 37 upward through the connecting rod 35. At this time, the air between the piston 37 and the sealing sleeve 34 enters the pressurizing chamber 331 through the connecting channel 304. As the pressure increases, the unlocking rod 333 gradually moves and pushes the limiting assembly to no longer limit the intermediate cylinder 33.

[0052] Then, as the exhaust control assembly moves, the pressurized chamber 331 and the inner bottom wall of the intermediate barrel 33 are connected to the outside, so that the pressure inside the pressurized chamber 331 and the intermediate barrel is restored to its original state. Then, as the outer barrel 306 and the intermediate barrel 33 move, the exhaust control assembly is closed.

[0053] When the handle 31 is removed, the piston 37 is reset under the action of the spring, at which time the one-way valve 303 opens, and the air below the piston 37 passes through the one-way valve 303 and enters above the piston 37 to ensure the next operation of the unlocking rod 333.

[0054] In this embodiment, two sealing plates 332 are provided in the pressurizing chamber 331, the sealing plates 332 are connected to the unlocking rod 333, and baffles are provided on both sides of the connection between the pressurizing chamber 331 and the communication channel 304;

[0055] When in use, the unlocking rod 333 and the pressurizing chamber 331 are sealed and plugged together through the two sealing plates 332, and the displacement range of the sealing plate 332 is limited by the baffle plate to prevent the sealing plate 332 from blocking the connection between the pressurizing chamber 331 and the connecting channel 304, thereby ensuring use.

[0056] In this embodiment, a limiting groove 101 is vertically provided on the inner wall of the outer cylinder 306 , and a ball located in the limiting groove 101 is provided on the middle cylinder 33 .

[0057] When in use, the displacement range of the intermediate tube 33 is realized through the cooperation of the limiting groove 101 and the ball, so as to prevent the plug-in board 302 from being separated from the inclined groove 39 and ensure the normal operation of the plug-in board 302.

[0059] The lower shaft 309 is provided with an exhaust hole 334 connected to the middle position of the pressurizing chamber 331 and the bottom of the inner wall of the intermediate cylinder 33. The exhaust hole 334 is connected to the side of the lower shaft 309.

[0060] When in use, as the outer cylinder 306 and the middle cylinder 33 move, the guide ball 308 gradually enters the lower pull groove, and the sealing cover 301 enters the arc groove 82. Then, the guide ball 308 gradually drives the sealing cover 301 to move downward along the lower pull groove, so that the exhaust hole 334 is gradually exposed, so that the exhaust hole 334 is connected to the outside, and when the pressurized chamber 331 and the inside of the middle cylinder 33 return to normal, the guide ball 308 drives the sealing cover 301 to move upward and reset, thereby ensuring the control of exhaust.

[0061] For the recovery of the internal pressure of the pressurized chamber 331 and the intermediate cylinder 33, the connection displacement length can be set according to actual needs to ensure the connection time.

[0063] When the sealing cover 301 does not move downward, gas enters the gas storage hole 307 and pushes the sealing cover 301 upward to ensure the sealing of the sealing cover 301.

[0064] In this embodiment, the limiting assembly includes a displacement hole 381 formed on the outer cylinder 306 and a locking rod 38 elastically inserted into the displacement hole 381.

When unlocking is required, the unlocking rod 333 pushes the locking rod 38 to move out of the limiting hole, so that the intermediate cylinder 33 can move upward.

[0066] After the unlocking rod 333 is extended, the outer wall of the middle tube 33 can only be leveled, so that the middle tube 33 can move up normally;

[0067] Preferably, the limiting hole and the contact portion of the locking rod 38 and the displacement hole 381 are all formed by a plurality of plates in a ring array to reduce friction.

[0069] When the outer cylinder 306 is close to one end of the displacement groove 9, the locking rod 38 is displaced along the guide groove 102 and gradually moves away from the intermediate cylinder 33 to reduce the friction between the locking rod 38 and the intermediate cylinder 33. When the locking rod 38 enters the step groove 103, the outer cylinder 306 contacts the limit plate 10. At this time, the outer cylinder 306 cannot continue to displace, and the locking rod 38 is inserted into the limit hole, and the displacement of the intermediate cylinder 33 is locked.
