A positioning slot is provided on the inner side of the first side board and at least a sloped surface is formed in the positioning slot. A manual stick is pivotally connected to the second side board and may be rotated. An engagement portion is provided on the stick. The holes-punching unit comprises a first side board, a second side board, a border adjusting assembly and a plurality of holes-punching members. A male positioning portion is provided on one end of the first side board. A sloped surface and an arc-shaped surface are provided on the male positioning portion. Therefore, as the holes-punching unit is fitted to the main body, accurate positioning and secured attachment may be achieved.
