[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The zinc-nickel alloy double-ended screw shown includes a shank 1, with threaded bodies 2 at both the top and bottom of the shank 1. The shank 1 and the threaded bodies 2 are made of zinc-nickel alloy.

[0025] Furthermore, an auxiliary mechanism 3 is provided on the outside of the rod 1. The auxiliary mechanism 3 includes an auxiliary ring 31 and a rotating plate 37. The auxiliary ring 31 facilitates connection with the rod 1 for easy installation and use. The rotating plate 37 facilitates rotation of the auxiliary ring 31, which in turn facilitates rotation of the rod 1 to prevent slippage. The auxiliary ring 31 is sleeved on the outside of the rod 1, and a connecting post 32 is fixedly connected to the inner wall of the auxiliary ring 31 to increase the stability of the connection between the auxiliary ring 31 and the rod 1, thereby facilitating the rotation of the auxiliary ring 31. To prevent the auxiliary ring 31 from slipping, the connecting post 32 is slidably mounted on the rod body 1. The rotating plate 37 is fixedly connected to the outer wall of the auxiliary ring 31. The outer side of the rod body 1 has a groove that matches the connecting post 32. One of the auxiliary rings 31 has a mounting post 38 symmetrically fixedly connected to its side, which facilitates the docking of the two auxiliary rings 31 and increases the stability of the auxiliary ring 31 installation. The other auxiliary ring 31 has an assembly groove symmetrically opened on its side, and the mounting post 38 is slidably inserted into the inner cavity of the assembly groove.

[0026] Specifically, the auxiliary ring 31 is fixedly connected to a fixing plate 33 on its side, which facilitates the support for the installation of the two auxiliary rings 31. The two fixing plates 33 are fixedly connected to the sides of their respective fixing plates 33, which facilitates the positioning of adjacent fixing plates 33. The other two fixing plates 33 have assembly grooves on their sides, and the insert plates slide through the inner cavity of these grooves. The top of the other two fixing plates 33 has a first sliding groove, and the top of the insert plates has a locking groove. A locking plate 34 is provided inside the first sliding groove, which facilitates the locking of the insert plates. The relative position of the locking plate 34 and the fixed plate 33 is defined, which facilitates the installation and removal of the auxiliary ring 31, allowing the auxiliary ring 31 to be used as needed. The locking plate 34 is slidably inserted into the inner cavity of the slot. The top of the locking plate 34 is fixedly connected to the traction plate 36, which facilitates the pulling of the locking plate 34 for traction operation. An arc-shaped plate 35 is fixedly connected between adjacent traction plates 36, which facilitates the movement of the traction plates 36 and makes it easy to connect the two traction plates 36 in series. The top of the other auxiliary ring 31 is... A fixed connection to the assembly column 39 facilitates connection with the arc-shaped plate 35, thereby facilitating the positioning of the arc-shaped plate 35 during installation. The top of the arc-shaped plate 35 has a circular groove that mates with the assembly column 39. A locking cap 310 is slidably inserted into the end of the assembly column 39, which helps to limit the relative position of the arc-shaped plate 35 and the assembly column 39, preventing the arc-shaped plate 35 from sliding freely. A square plate 311 is provided on the outside of the locking cap 310, which facilitates the pulling of the assembly rod 312 and allows for easy traction of the assembly rod 312. An assembly rod 312 is fixedly connected to the side of the 311. A second sliding groove that mates with the assembly rod 312 is opened on the outside of the locking cap 310. A third sliding groove that mates with the assembly rod 312 is opened on the outer wall of the assembly column 39. Elastic ropes 313 are symmetrically embedded on the side of the square plate 311. The tension of the elastic ropes 313 is conducive to pulling the square plate 311 to move, so that the square plate 311 and the assembly rod 312 can return to their original positions after movement, and it is convenient to repeat the operation of the assembly rod 312. One end of the elastic rope 313 is fixedly connected to the locking cap 310.
