[0025] As attached Figure 2 As shown, the lifting stroke adjustment mechanism 9 includes an upper connecting block 91, a lower connecting block 92, a slide 93, a rotating rod 94, a driving gear 95, a passive gear 96, a screw 97, and a limit block 98. The slide 93 is slidably connected to the vertical track. The upper connecting block 91 and the lower connecting block 92 are fixed to the slide 93 from top to bottom.
