Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0020] Refer to Figures 1-4 As shown, a specific embodiment of a linkage mechanism of the present utility model includes a main protection plate 10, a sub-protection plate 20, a toothed bar 30, a toothed block 40, and a linkage wheel 50. The main protection plate 10 and the sub-protection plate 20 are riveted and buckled together as a whole, and the toothed bar 30, the toothed block 40, and the linkage wheel 50 are arranged inside this overall structure;

[0021] The main protection plate 10 is provided with a first riveting hole 11 and a connecting pin 12, and the sub-protection plate 20 is provided with a second riveting hole 21 and a pin shaft hole 22 that cooperate with it. The two are fixedly connected as a whole through the connecting pin and the pin shaft hole.

[0022] The linkage wheel seat 23 is provided on the auxiliary guard plate 20, and the linkage wheel 50 is installed on the linkage wheel seat 23. The linkage wheel 50 cooperates with the toothed strip 30 and also with the toothed block 40. The main guard plate 10 is provided with a first slot 13, and the auxiliary guard plate 20 is provided with a second slot 24. After the two are combined into a whole, the first slot 13 and the second slot 24 are combined to form a linkage channel 60. The toothed strip 30 is in an L shape, the toothed strip 30 is provided with a first linkage hanging point 31, and the toothed block 40 is provided with a second linkage hanging point 41.
