The utility model relates to a height-adjustable type accounting voucher flattening device. Many traditional flattening devices exist, however the height of supporting rods is unadjustable, grooves are lacked in a floor, and meanwhile the biggest problem is that the device is fixed through a pin by pressing downwards a compression bar, and a lot of time and strength are consumed.

The inner sides of the set of telescopic supporting stand columns are provided with a set of limiting baffles (5). The set of telescopic supporting stand columns are connected with a supporting beam (4). The supporting beam is connected with a threaded rod (3) through a threaded rod connection piece (2). The top end of the threaded rod is connected with a rotating handle (1). The bottom end of the threaded rod is connected with a pressing plate (10) through a pressing plate connection piece (11).
