The outer surface of the second limiting block 705 is installed with an anti-slip structure 8, and the anti-slip structure 8 includes an upper cover 801, a spring 802, an inner sleeve 803, steel balls 804, a bottom shell 805, a bottom plate 806 and a steel needle 807. The upper surface of the bottom plate 806 is installed with the upper cover 801, and the bottom plate 806 and the upper cover 801 form an installation cavity, and the bottom shell 805 is installed inside the installation cavity, and the inner sleeve 803 is installed inside the bottom shell 805. The outer surface of the inner sleeve 803 is provided with an installation port, and the installation ports are fixed to three and evenly distributed, and steel balls 804 are installed inside the installation ports.

[0027] The inner surface of the inner sleeve 803 is provided with a mounting ring 80301 , the upper surface of the mounting ring 80301 is installed with a spring 802 , and the other end of the spring 802 is installed on the inner top of the upper cover 801 .

[0028] A through hole is provided on the lower surface of the first limit block 704, one end of which passes through the first limit block 704 and the second limit block 705 and extends to the interior of the installation cavity. A steel needle 807 is slidably connected to the interior of the through hole, and the outer surface of the steel needle 807 abuts against the outer surface of the steel ball 804.

[0029] A second limiting rivet 9 is installed at one end of the upper mounting plate 1 close to the lower mounting plate 2 , and a torsion spring 10 is installed on the outer surface of the second limiting rivet 9 , and one end of the torsion spring 10 abuts against the outer surface of the shifting block 4 .

[0030] A third limiting rivet 11 is installed at one end of the lock hook 5, and a tension spring 12 is installed on the outer surface of the third limiting rivet 11.

Then, the steel needle 807 cannot be pulled out at this time, which plays a good fixing role and prevents the unlocking rod from separating from the fixing part 7 during use. When the unlocking rod needs to be replaced, first place the magnet on the upper surface of the upper cover 801, so that the inner sleeve 803 drives the steel ball 804 to continue to move upward, and at the same time the spring 802 is gradually compressed. When the inner sleeve 803 drives the steel ball 804 to continue to move upward, the outer surface of the steel ball 804 gradually loses contact with the outer surface of the steel needle 807. At this time, the steel needle 807 can be pulled outward to make the steel needle 807 detach from the inside of the installation cavity, so that the first limit block 704 and the second limit block 705 cancel the fixing tube, thereby facilitating the replacement of the unlocking rod.
