The fall arrestor clamping block 33 is connected to the swing rod 31 and extends into the cable passage 20a as the swing rod 31 swings, so that the fall arrestor clamping block 33 clamps the external cable with the inner wall of the cable passage 20a; the swing rod 31 is used for the external safety rope to pass through; at least one first roller 40 is connected to the support base 10 and arranged relative to the cable passage 20a. The first roller 40 is used to roll and contact the external cable so that when a person falls, the swing rod 31 swings downward, which facilitates the fall arrestor clamping block 33 clamping the external cable with the inner wall of the cable passage 20a, ensuring the clamping of the external cable by the fall arrestor 100, avoiding the need for manual pulling of the swing rod 31 without timely pulling, and improving the safety of the fall arrestor 100.

[0047] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the support base 10 serves as a support component of the fall arrester 100, and the support base 10 is used to support the movable base 20, the fall arrester 30, and at least one first roller 40.

[0048] The movable base 20 is disposed inside the support base 10. The movable base 20 is movably connected to the support base 10 and elastically moves relative to the support base 10 to adjust the position of the movable base 20 relative to the support base 10. The movable base 20 is provided with a cable passage groove 20a for external cables to pass through. The cable passage groove 20a extends through the movable base 20 along its length to allow external cables to pass through the space of the cable passage groove 20a. At the same time, the size of the cable passage groove 20a can be adjusted by moving the movable base 20 relative to the support base 10, thereby facilitating the adaptation of the cable passage groove 20a to external cables of different diameters.

[0049] The fall arrestor assembly 30 includes a swing rod 31, an elastic module 32, and a fall arrestor clamping block 33. The swing rod 31 is built into the movable seat 20 and is swayably connected to the movable seat 20, swinging along the axis of the connection between the swing rod 31 and the movable seat 20 to adjust the position of the swing rod 31 relative to the movable seat 20.

The fall arrestor clamping block 33 is connected to the swing rod 31 and, as it moves, adjusts its position relative to the movable seat 20. The swing rod 31 extends into the cable tray 20a by swinging, so that the fall arresting clamping block 33 engages with the inner wall of the cable tray 20a to clamp the external cable; the swing rod 31 is used for the external safety rope to pass through; so that when a person falls, the swing rod 31 swings downward, thereby facilitating the fall arresting clamping block 33 to engage with the inner wall of the cable tray 20a to clamp the external cable, ensuring the clamping of the external cable by the fall arrestor 100, avoiding the need for manual pulling of the swing rod 31 without timely pulling, and improving the safety of the fall arrestor 100.

[0050] At least one first roller 40 is connected to the support base 10 and arranged relative to the cable tray 20a. The first roller 40 is used to roll and contact the external cable, so that the external cable passes through the cable tray 20a under the guidance of the first roller 40, ensuring the smooth extension of the external cable. At the same time, the external cable makes contact with the arc surface of the support base 10 through the first roller 40, preventing the support base 10 from cutting the external cable and extending the service life of the external cable. Specifically, there are two first rollers 40, which are arranged relative to the upper and lower ends of the support base 10, respectively.

[0051] Please refer to the attached document. Figures 1-3 In this embodiment, the support base 10 is provided with a first receiving cavity 10a and a moving groove 10b; the moving groove 10b is disposed on one side of the first receiving cavity 10a and communicates with the first receiving cavity 10a; the moving seat 20 is located inside the first receiving cavity 10a and is movably connected to the first receiving cavity 10a, so that the moving seat 20 can move relative to the support base 10 through the first receiving cavity 10a; the moving seat 20 moves along the width direction of the support base 10, so as to adjust the width position of the moving seat 20 relative to the support base 10. Specifically, there is a clearance fit between the inner contour of the moving seat 20 and the inner contour of the first receiving cavity 10a to achieve the movement effect of the moving seat 20 relative to the first receiving cavity 10a.

[0052] The movable seat 20 is connected to a connector 21, which extends from the first receiving cavity 10a to the moving groove 10b. The connector 21 moves with the movable seat 20. The connector 21 passes through the moving groove 10b and is movably connected to the moving groove 10b so as to adjust the position of the connector 21 relative to the moving groove 10b. This allows the inner contour of the moving groove 10b to limit the range of movement of the connector 21 and prevent the movable seat 20 from detaching from the support seat 10.

[0053] Please refer to the attached document. Figures 1-4 In this embodiment, the connector 21 is a screw connected to the movable seat 20 and moving within the movable groove 10b. The movable groove 10b contains a first elastic member 22, which is located within the groove and elastically contacts the inner wall of the groove 10b and the screw. This allows the first elastic member 22 to apply an elastic force to the screw, ensuring adequate space in the cable tray 20a and preventing the cable tray 20a from becoming too large and causing the external cable to deviate from the first roller 40. Specifically, multiple connectors 21 are arranged relative to the two side walls of the movable seat 20, ensuring the stability of the movable seat 20's movement relative to the support base 10. Optionally, four connectors 21 are arranged, with two connectors arranged relative to the front side wall of the movable seat 20 and the other two relative to the rear side wall.

[0054] Please refer to the attached document. Figures 1-3 In this embodiment, the support base 10 is connected to a limiting member 11. The limiting member 11 is detachably connected to the support base 10 and arranged relative to the moving groove 10b, allowing the limiting member 11 to connect to or detach from the support base 10. When the limiting member 11 is connected to the support base 10, it covers the first elastic member 22 located in the moving groove 10b, so that the outer wall of the moving base 20 and the inner wall of the limiting member 11 restrict the first elastic member 22, preventing deformation of the first elastic member 22. Specifically, the limiting member 11 is detachably connected to the support base 10 by bolts.

[0055] Please refer to the attached document. Figures 1-4 In this embodiment, the movable base 20 is further provided with a wire hole 20b, which is located in the middle of the movable base 20 and is laterally connected to the wire groove 20a. The wire hole 20b is opened in the movable base 20 in a horizontal direction, and the opening of the wire hole 20b is exposed to and connected to the external environment. The external cable enters the opening of the wire hole 20b in a horizontal direction and is transferred to the wire groove 20a through the wire hole 20b. The external cable is in the vertical direction when passing through the wire groove 20a, so that the external cable can extend from the external environment through the wire hole 20b to the wire groove 20a.

[0056] Please refer to the attached document. Figures 1-4In this embodiment, the movable seat 20 is provided with a second receiving cavity 20c, which serves as the internal space of the movable seat 20. The second receiving cavity 20c is connected to the wire groove 20a along the horizontal direction. The swing rod 31, the elastic module 32, and the anti-fall clamping block 33 are all located in the second receiving cavity 20c of the movable seat 20, so that the swing rod 31, the elastic module 32, and the anti-fall clamping block 33 can make full use of the space of the second receiving cavity 20c.

[0057] The swing rod 31 is hinged to the movable seat 20 and swings along the hinge point between the swing rod 31 and the movable seat 20, so that the swing rod 31 can swing relative to the movable seat 20 through the hinge. The fall arresting clamp 33 extends or retracts into the cable passage 20a as the swing rod 31 swings. When the swing rod 31 swings upward, the fall arresting clamp 33 retracts into the cable passage 20a as the swing rod 31 swings, so that the external cable can be threaded through the cable passage 20a. When a person falls and the swing rod 31 swings downward through the safety rope, the fall arresting clamp 33 extends out of the cable passage 20a as the swing rod 31 swings, so that the fall arresting clamp 33 can clamp the external cable with the inner wall of the cable passage 20a, ensuring that the fall arrester 100 clamps the external cable, avoiding the need for manual pulling of the swing rod 31 and improving the safety of the fall arrester 100.

[0058] Please refer to the attached document. Figures 1-3 5. In this embodiment of the application, the elastic module 32 includes a guide seat 321, a moving rod 322, and a second elastic element 323; the guide seat 321 is located in the second receiving cavity 20c of the moving seat 20 and is connected to the moving seat 20; so that the guide seat 321 is fixed in the second receiving cavity 20c of the moving seat 20, thereby facilitating the guide seat 321 to be in a stationary state relative to the moving seat 20.

[0059] The movable rod 322 is movably inserted through the guide seat 321 and can move vertically to adjust its height relative to the guide seat 321. A second roller 3221 is connected to the end of the movable rod 322 facing the swing rod 31. The second roller 3221 rolls against the side wall of the swing rod 31, allowing the movable rod 322 to abut against the side wall of the swing rod 31 via the second roller 3221. A second elastic element 323 is sleeved on the movable rod 322 and positioned between the guide seat 321 and the movable rod 322. The second elastic element 323 applies an elastic downward pressure to the second roller 3221, ensuring continuous contact between the second roller 3221 and the side wall of the swing rod 31. This prevents the swing rod 31 from swinging unintentionally, maintaining its swing state relative to the movable seat 20 and preventing accidental adjustment of the swing rod 31.

[0060] Please refer to the attached document. Figure 5In this embodiment, the sidewall of the swing rod 31 is arranged along an inclined direction. The second roller 3221 contacts different positions of the sidewall of the swing rod 31 as the swing rod 31 swings, so that the swing rod 31 can make contact with the arc surface of the moving rod 322 under the action of the second roller 3221, thus ensuring the smooth swing of the swing rod 31.

[0061] Please refer to the attached document. Figures 1-3 5. In this embodiment, the anti-fall clamping block 33 is connected to the swing rod 31 and its position is adjusted as the swing rod 31 swings, so that the anti-fall clamping block 33 can extend or retract into the cable passage 20a. The side wall of the anti-fall clamping block 33 facing the cable passage 20a is provided with an arc-shaped groove 33a, which is connected to the cable passage 20a in the horizontal direction and together with the cable passage 20a, allows external cables to pass through, so that external cables can pass through the space of the arc-shaped groove 33a to pass through the anti-fall clamping block 33. When the anti-fall clamping block 33 retracts into the cable passage 20a, it allows the external cable to move relative to the arc groove 33a and the cable passage 20a. When the anti-fall clamping block 33 extends out of the cable passage 20a, it allows the inner wall of the cable passage 20a and the inner wall of the arc groove 33a to clamp the external cable, thereby restricting the peripheral position of the external cable and preventing the external cable from slipping relative to the anti-fall clamping block 33 and shifting its position, thus causing a second fall.

[0062] Please refer to the attached document. Figures 1-3 5. In this embodiment, the swing arm 31 is provided with a limiting groove 31a; the anti-fall clamping block 33 is connected to the limiting groove 31a and can be limited by the inner wall of the limiting groove 31a; preventing the anti-fall clamping block 33 from retracting too far. The swing arm 31 is provided with an operating part 311, which is located outside the second receiving cavity 20c and exposed to the external environment, so that the external safety rope of the external environment can pass through the operating part 311, thereby facilitating the swing of the operating part 311 by the external safety rope when a person falls, so as to realize that the anti-fall clamping block 33 can clamp the external cable by combining with the inner wall of the cable groove 20a.
