Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

the invention provides a portable hand punch press as shown in figures 1-3, which comprises a hand grab handle 1, wherein the hand grab handle 1 is arc-shaped, a fixed shaft wheel rotating system 3 is arranged above the hand grab handle 1, the fixed shaft wheel rotating system 3 is hexagonal, a driving wheel is respectively arranged at the front and the rear of the fixed shaft wheel rotating system 3, a fixed handle 2 is fixed behind the fixed shaft wheel rotating system 3, a gear turntable 4 is arranged above the fixed shaft wheel rotating system 3, a hand crank 5 rotating along the circular plane of the gear turntable 4 is arranged above the circle center of the gear turntable 4, an upper cutter slot 6 is arranged in front of the fixed shaft wheel rotating system 3, and a drill bit 7 is arranged in front of the upper cutter slot 6.

Example 2:
