[0005] Furthermore, the pull ring is provided with a connection structure, the bottom of the connection structure is provided with a threaded hole, and the end of the screw is threadedly connected to the bottom of the connection structure, which is convenient for installation and use. Of course, other detachable connection structures can also be designed.

[0006] Furthermore, the connection structure is in a cross shape, and the two sides are integrally formed with the pull ring.

[0007] Furthermore, the adjustable U-shaped ring includes a U-shaped ring body, telescopic rods are arranged inside the two sides of the U-shaped ring body, mounting holes are arranged at the ends of the telescopic rods, and a series of latch holes are correspondingly opened on the U-shaped ring body and the telescopic rods for the installation of locking latches. Of course, other adjustable structures can also be designed.

[0008] Furthermore, the U-shaped ring body is a U-shaped pipe structure.

[0009] Furthermore, the locking latch comprises a latch rod, on which a locking member is inserted. Of course, other structures can also be designed.

[0010] Furthermore, it also includes a safety rope, which has two knot points, respectively connected to the pull ring and the adjustable U-shaped ring, wherein the two knot points have a double insurance function.

[0011] Compared with the prior art, the utility model has the following beneficial effects: simple structure, easy manufacturing and low cost, detachable, easy installation and use, the two pulling nodes have double insurance functions, which can ensure that the safety rope is tied and fixed stably, reliably and safely, and can be used on indoor walls as a reliable pulling point for the safety rope.

[0017] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Reference Figures 1 to 3 An adjustable safety rope knotting device comprises a screw rod 1, a pull ring 2, an adjustable U-shaped ring 3, a locking pin 4 and a nut 5. One end of the screw rod 1 passes through the adjustable U-shaped ring 3, and the adjustable U-shaped ring 3 is fixed by the nuts 5 on both sides of the screw rod 1. The pull ring 2 is detachably connected to one end of the screw rod 1. The locking pin 4 is installed on the adjustable U-shaped ring 3. The length of the adjustable U-shaped ring 3 is adjusted according to the position of the screw hole on the shear wall.

[0019] In this embodiment, a connection structure 2-1 is provided on the pull ring 2, a threaded hole is provided at the bottom of the connection structure 2-1, and the end of the screw rod 1 is threadedly connected to the bottom of the connection structure 2-1 for easy installation and use.

[0020] In this embodiment, the connection structure 2 - 1 is in a cross shape, and the two sides are integrally formed with the pull ring 2 .

[0021] In this embodiment, the adjustable U-shaped ring 3 includes a U-shaped ring body 3-1, and telescopic rods 3-2 are provided inside the two sides of the U-shaped ring body 3-1. The ends of the telescopic rods 3-2 are provided with mounting holes 3-3, and a series of pin holes 3-4 are correspondingly opened on the U-shaped ring body 3-1 and the telescopic rods 3-2 for the installation of locking pins 4.
