In this way, the spacing adjustment of the two vertical pruning mechanisms 4 can be realized by the movement of the sliding block body 4011, and the fixation of the two vertical pruning mechanisms 4 can be realized by the plug-in cooperation of the plug 4012 and the plug groove 3011.

[0032] In this embodiment, the elastic penetration of the plug 4012 is realized by a spring, and when the sliding block body 4011 slides, the fixing member 4013 is fixed first, at this time, the plug 4012 is in elastic compression, and when the sliding block body 4011 is in place, the fixing member 4013 is released, and the plug 4012 is automatically inserted into the plug groove 3011.

[0033] And in the embodiment, the first trimming arm 301 can be provided with two, and the corresponding plug 4012 in the sliding block assembly 401 can also be provided with two;

[0034] And in the embodiment, the two sliding block bodies 4011 can be synchronously moved through a linear driver;
