The width of extension section 503a is less than the width of guide slot 102c for can not produce the contact between extension section 503a and the guide slot 102c, spacing section 503b can extend to the inboard of guide slot 102c, and the laminating of spacing section 503 b's both sides and guide slot 102 c's both sides can avoid action member 401 to appear rocking the problem, and friction section 503c can't pass through guide slot 102c.
When the water level rises, the traction rope 300 pulls the sliding column 402, the sliding column 402 drives the limiting member 404 to move and press the first elastic piece 403, the retracted surface 404b of the limiting member 404 is abutted against the transverse moving column 501b instead of the abutting surface 404a, the transverse moving column 501b moves towards the limiting member 404 under the pushing of the second elastic piece 501d, and the friction member 503 is pulled to move towards the limiting member 404 through the cavity head 501e, so that the friction section 503c of the friction member 503 is attached to the parallel inner frame 102b, and the friction force during the movement of the actuating member 401 is increased, so that the traction rope 300 can be stably tensioned.
When the water level drops, the pulling force of the traction rope 300 on the sliding column 402 disappears, under the pushing of the first elastic piece 403, the limiting member 404 is reset, and the abutting surface 404a of the limiting member 404 is abutted against the retracted surface 404b and the lateral sliding column 501b, so that the abutting surface 404a of the limiting member 404 can push the lateral sliding column 501b to move away from the limiting member 404, the lateral sliding column 501b pushes the cavity head 501e, the cavity head 501e pushes the friction member 503 to move away from the limiting member 404, so that the friction section 503c in the friction member 503 is separated from the parallel inner frame 102b, and meanwhile, the bead 502b enters the inner side of the ball groove 102c-1, so that the friction force when the acting member 401 moves is reduced when the acting member 401 moves along the parallel inner frame 102b, and the traction rope 300 can be stably pulled when the acting member 401 moves downwards.
Further, before the traverse column 501b contacts the contact surface 404a, the bead body 502b enters the inner side of the ball groove 102c-1, the limiting section 503b is still located at the inner side of the guide groove 102c, and along with the pushing of the first elastic element 403, the limiting member 404 continues to reset, at this time, the retracted surface 404b continues to push the traverse column 501b, so that the cavity head 501e continues to move away from the limiting member 404, the limiting section 503b is pushed away from the inner side of the guide groove 102c, the problem of friction between the limiting section 503b and the inner wall of the guide groove 102c is avoided, and after the bead body 502b enters the inner side of the ball groove 102c-1, a certain space is still provided for the cavity head 501e to move away from the limiting member 404.
The rest of the structure is the same as in embodiment 2.
