The observation window 8 on the front allows the operator to clearly view the working area ahead. The moving block 9 inside can achieve further adjustment or operation requirements, ensuring the flexibility and efficiency of the operation. The lifting device 2 includes a sliding rod 21, which is fixedly connected to the bottom of the moving block 9. The outer wall of the sliding rod 21 is slidably connected with a sleeve 22. On the front inner wall of the sleeve 22, a fixing plate 23 is fixedly connected. The bottom of the fixing plate 23 is rotatably connected to a lead screw 24 through a bearing. The bottom of the lead screw 24 is fixedly connected with a first bevel gear 25. On the left side inner wall of the sleeve 22, a rotating rod 26 is rotatably connected through a bearing. On the right side of the rotating rod 26, a second bevel gear 27 is fixedly connected. The rotating rod 26 extends to the left through the sleeve 22. On the left side of the sleeve 22, a first motor 28 is fixedly connected. The output end of the first motor 28 is fixedly connected to the extended end of the rotating rod 26. The sliding rod 21 is fixed to the bottom of the moving block 9, and the sleeve 22 slides around the sliding rod 21. The fixing plate 23 is fixedly connected to the inner wall of the sleeve 22 and is connected to the lead screw 24 through a bearing. The rotation of the lead screw 24 is achieved through the meshing of the first bevel gear 25 and the second bevel gear 27.
