In this embodiment, the setting angle α is preferably 90 °, and this is described in the state, but in this embodiment, the setting angle α is not too small, and the stability of the fixing manner is insufficient due to too small rotation angle. Firstly, in order to ensure that the punch structure 4 can be fixed after being installed, the punch structure 4 needs to be fixed in both the vertical direction and the horizontal direction, the fixing in the vertical direction can be realized by setting the height of the locking groove 17b to be consistent with the thickness of the cross bar at the bottom of the locking structure 3, and for the fixing in the horizontal direction, the locking structures 3 are arranged at two sides of the punch holder 7, the angles of the locking structures 3 at the two sides are the same but opposite, the locking structures 3 at the two sides and the locking groove 17b are matched and limited after rotation, as shown in fig. 4, 5 and 6, the matched limit of the locking structures 3 at the two sides and the locking groove 17b is understood to be central symmetry along the center of the punch holder 7, after the punch structure 4 is installed, when the punch structure 4 is shifted towards one side, the locking structure 3 at the other side can prevent the punch structure 4 from moving, and the locking structures 3 at the two sides form a mutual dragging effect on the punch structure 4, so that the position is ensured after the punch structure 4 is installed; in practice, when the punch is installed, only the locking structures 3 on two sides are required to slide in from the tops of the punch structures 4 respectively, then the locking structures 3 on two sides are reversely rotated by the set angle alpha respectively, so that the punch structures 4 can be kept fixed, the operation is simple and quick, time and labor are saved, and meanwhile, the stability is good.

Specifically, referring to fig. 4, the locking structure 3 includes a rotating portion 10 located above the punch holder 7, a connecting portion 12 pivotally mounted on the punch holder 7, and a clamping portion 15 adapted to the locking groove 17b, where the rotating portion 10 and the connecting portion 12, the connecting portion 12 and the clamping portion 15 are all vertically connected, the locking groove 17b is a semicircular groove, and openings of the two locking grooves 17b on two sides are opposite, referring to fig. 5 and 6, the length of the clamping portion 15 is the same as the radius of the semicircular groove (for convenience of illustration, the clamping portion 15 is slightly shorter than the radius of the semicircular groove, and is actually required to be the same), so that the two locking structures 3 on two sides reversely rotate and then limit the punch structure 4 in opposite directions. In the drawings, the rotation part 10, the connection part 12 and the clamping part 15 are circular rods, and in practice, simple deformation such as square rods can be realized. As can be seen from fig. 5, the left connecting part 12 can be moved to the left in the drawing, and the right connecting part 12 can be moved to the right in fig. 6, but when the upper punch structure 4 is moved to the left as a whole, the right connecting part 12 cannot be moved, i.e. is restrained, and the other directions are the same, so that the locking structures 3 on both sides can ensure stable installation of the punch structure 4. Of course, the semicircular groove is only a preferred mode in the above embodiment, and in fact, a quarter of the circular groove can be used as an alternative, on the basis of which, it is anticipated that more shapes can be selected, and the embodiment is not expanded one by one.
