[0020] To make the application objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0021] Referring to Figure 1 、 Figure 2 and Figure 3 , a disassembly tool for the locking card of the pre-finishing mill unit of a high-speed wire rod mill, comprising a disassembly wrench 1 and a wrench handle 2. One side of the disassembly wrench 1 is fixed with the wrench handle 2. An annular groove is formed inside one end of the disassembly wrench 1 away from the wrench handle 2, and the end of the center groove away from the wrench handle 2 is open. A number of limiting protrusions 3 are fixedly arranged at equal intervals inside the end of the disassembly wrench 1 away from the wrench handle 2. Each limiting protrusion 3 is fixed on the inner wall of the annular groove, and each limiting protrusion 3 is arranged in an arc shape matching the annular groove. A fixing screw 5 is fixed at the bottom of the end of the wrench handle 2 away from the disassembly wrench 1, and an auxiliary handle 4 is rotatably sleeved on the fixing screw 5. A fixing clamp 6 is threadedly sleeved on the fixing screw 5 on the bottom surface of the auxiliary handle 4.

[0022] Specifically, when the disassembly tool needs to be used, the disassembly wrench 1 is sleeved on the locking card, and the limiting protrusions 3 are aligned with the grooves of the locking card one by one. Then, the fixing clamp 6 is rotated to release the clamping and fixing of the auxiliary handle 4 by the fixing clamp 6. The fixing screw 5 can be rotated. After the fixing screw 5 is rotated to be aligned in the opposite direction to the wrench handle 2, the fixing clamp 6 is rotated to make the fixing clamp 6 clamp and fix the auxiliary handle 4 again. The auxiliary handle 4 can be held to rotate the disassembly wrench 1. After increasing the torque, it is more labor-saving when the disassembly wrench 1 rotates. After use, the fixing clamp 6 is rotated again to rotate the auxiliary handle 4 to the bottom surface of the wrench handle 2 and coincide with it, and then the fixing clamp 6 is rotated to fix it again.

[0023] As an optimized solution, as Figure 3 shown, a support screw 7 is slidably sleeved inside the wrench handle 2 between the auxiliary handle 4 and the annular groove. Upper limit plates 9 and lower limit plates 8 are respectively movably sleeved on the support screw 7 above and below the wrench handle 2. The lengths of the lower limit plate 8 and the upper limit plate 9 are both greater than the distance between the support screw 7 and the annular groove. Rotation holes matching the support screw 7 are formed inside the lower limit plate 8 and the upper limit plate 9. A jacking hole matching the middle part of the support screw 7 is formed inside the wrench handle 2. The support screw 7 is arranged in a "work" shape. A fixing nut 10 is threadedly sleeved on the support screw 7 on the top surface of the upper limit plate 9 above.

[0024] Specifically, when the disassembly wrench 1 is sleeved on the locking card, and then according to the position space at the upper and lower ends of the locking card, select the lower limit plate 8, the upper limit plate 9, or both the lower limit plate 8 and the upper limit plate 9, and place them at the upper and lower ends of the locking card, so that the lower limit plate 8, the upper limit plate 9, or both the lower limit plate 8 and the upper limit plate 9 abut against the locking card, and then turn the fixing nut 10 to clamp the upper limit plate 9 with the fixing nut 10, then the disassembly wrench 1 can be fixed on the locking card, further improving the stability of the disassembly tool during use. After the disassembly is completed, turn the fixing nut 10 to loosen the clamping of the lower limit plate 8, the upper limit plate 9, or both the lower limit plate 8 and the upper limit plate 9 on the locking card, and then the disassembly wrench 1 can be removed from the locking card.
