DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] See also Figure 1-4 , a multi-hole punching machine in this embodiment includes a driving member 2 and a connecting member 3, the driving member 2 is connected to the connecting member 3, and a punching head 8 is provided on the driving member 2, and a mounting groove 5 is opened on the bottom surface of the connecting member 3 along the longitudinal direction, and a mounting block 4 is detachably fixed in the mounting groove 5, and a groove 7 is opened vertically on the left side of the mounting block 4, and a fixed block 6 is detachably fixed in the groove 7, and a rotating block 9 is provided on the outer side of the fixed block 6, and the fixed block 6 and the rotating block 9 are hinged by a rotating shaft 10. The bottom surface of the rotating block 9 passes through and extends to the outside of the groove 7, and the punching head 8 is fixed to the bottom end of the rotating block 9. The inner left wall of the mounting groove 5 corresponds to the connecting groove 15 and is provided with an accommodating groove 12 on the connecting member 3 along the transverse direction. The bottom surface of the connecting member 3 corresponds to the accommodating groove 12 and is provided with a connecting groove 15 along the longitudinal direction. The accommodating groove 12 is connected to the connecting groove 15, and a baffle 14 is provided in the connecting groove 15, which abuts on the left side of the rotating block 9.

[0023] During application, when the number of punching holes needs to be reduced, the number of punching heads 8 involved in the punching holes can be reduced. When the number of punching holes needs to be reduced, the movable baffle 14 is moved out of the connecting groove 15 to release the blockade of the receiving groove 12. In the process of the baffle 14 being moved out of the connecting groove 15, the baffle 14 will slide on the outside of the fixed block 6 and the rotating block 9. When the baffle 14 moves to separate from the two, the rotating block 9 can rotate toward the baffle 14. After the rotating block 9 rotates toward the baffle 14, it will drive the punching head 8 to rotate together and position In the accommodating groove 12, at this time, the mounting block 4, the rotating block 9 and the punch head 8 change from a vertical distribution to an L-shaped distribution. After the punch head 8 moves into the accommodating groove 12, the baffle 14 is reset and the baffle 14 is fixed in the connecting groove 15. At this time, the rotating block 9, the punch head 8 and the top surface of the baffle 14 are in contact, and the baffle 14 blocks the punch head 8 in the accommodating groove 12, thereby realizing the deletion of the punch head 8. In the deletion process, there is no need to remove the punch head 8 from the connecting part 3, which effectively shortens the time required for deleting the punch head 8 and improves work efficiency.

[0024] Example 2:

[0025] The basic content of Example 1 is different in that:

[0026] See also Figure 1-4 In this embodiment, the baffle 14 is slidably connected to the left side of the fixed block 6 and the rotating block 9. The width of the baffle 14 is adapted to the width of the inner cavity of the connecting groove 15. The width of the rotating block 9 is equal to that of the punching head. The width of the inner cavity of the accommodating groove 12 is greater than the width of the rotating block 9 and the punching head. The rotating block 9 rotates clockwise with the rotating shaft 10 as the center. The number of punching heads 8 is several, and the number of grooves 7, accommodating grooves 12 and punching heads 8 corresponds to each other.

[0027] During application, when the punching of several punching heads 8 does not meet the use requirements, the punching heads 8 can be accommodated in the accommodating groove 12 to reduce the number of punching heads 8 involved in punching. When the baffle 14 releases the blockade of the rotating block 9 and the punching head 8, the rotating block 9 and the punching head 8 can be moved clockwise to the accommodating groove 12 for accommodation.

[0028] Example 3:

[0029] The basic content of Example 1 is different in that:

[0030] See also Figure 4 , the baffle 14 in this embodiment is slidably connected in the connecting groove 15, and the front of the baffle 14 is connected to the inner positive wall of the connecting groove 15 through a hinge seat. A placement groove 13 is provided on the bottom surface of the baffle 14 near the inner back wall of the connecting groove 15, and a spring 16 is fixed to the inner positive wall of the placement groove 13. A limit block 18 is fixed on one end of the spring 16 away from the inner positive wall of the placement groove 13, and a limit groove 17 is provided on the inner back wall of the placement groove 13 corresponding to the limit block 18. The end of the limit block 18 away from the spring 16 passes through the baffle 14 and extends into the limit groove 17. The limit block 18 is slidably inserted into the limit groove 17, and the limit block 18 is clearance-matched with the limit hole. The limit block 18 moves linearly back and forth in the limit hole. A shift block is fixed on the bottom surface of the limit block 18, and a through hole for the limit block 18 to pass through is provided on the back of the baffle 14, and the through hole is connected to the placement groove 13.

[0031] When in use, the limit block 18 is moved by the shift block so that the limit block 18 is moved out of the limit groove 17. When the limit block 18 moves, the limit block 18 will squeeze the spring 16, causing the spring 16 to contract. When the limit block 18 moves into the perforation, the fixation of the baffle 14 can be released, and the baffle 14 is rotated to facilitate the reception of the punch head 8 into the receiving groove 12. After the punch head 8 is received into the receiving groove 12, the baffle 14 is reset, and then the limit block 18 moved into the perforation is released. At this time, the spring 16 is no longer squeezed, and the limit block 18 is moved back into the limit groove 17 under the action of the elastic force of the spring 16, thereby fixing the baffle 14.

[0032] Example 4:

[0033] The basic content of Example 1 is different in that:

[0034] See also Figure 1 In this embodiment, a base plate 11 is provided below the punching head 8 , a mounting frame 1 is fixed on the base plate 11 , and a driving member 2 is provided on the mounting frame 1 .

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
