[0028] To sum up, the lifting cab structure can indirectly drive the limit block 7 to move out of the limit hole 5 by controlling the hand-held rod 10, thereby releasing the fixation between the movable rod 4 and the fixed rod 3. Subsequently, because the output end of the electro-hydraulic push rod 16 is extended or contracted, the cab body 18 can be indirectly driven to move upward or downward. Finally, the limit block 7 is controlled to be inserted into the limit hole 5 at the specified position, and the movable rod 4 and the fixed rod 3 can be re-fixed, so that the device can realize the function of lifting and lowering the cab body 18, which is convenient for the staff to effectively adjust the height of the cab body 18 according to work requirements, thereby greatly improving the applicability of the cab body 18.

[0029] The lifting cab structure continuously squeezes the moving block 8 outward through the reaction force generated by the extrusion of the return spring 13, so that the moving block 8 drives the limiting block 7 to move outward along the inside of the connecting block 6 until the limiting block 7 passes through the inner side of the fixed rod 3 and is finally firmly inserted into the inside of the limiting hole 5 at the designated position, effectively improving the fixing effect between the fixed rod 3 and the moving rod 4, and indirectly ensuring the stability of the cab body 18 when it is in use.

[0030] The lifting cab structure, through the mutual cooperation between the four groups of fixing pins 2, allows the staff to control the hammer to knock the fixing pins 2 downward, so that part of the fixing pins 2 pass through the lower surface of the base plate 1 and finally are firmly inserted into the inside of the ground, thereby achieving effective fixation between the device and the ground and improving the stability of the device when it is in use.
