Detailed Implementation

[0015] The portable pressure ring punching device of this utility model will now be further described in conjunction with the accompanying drawings.

[0016] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0017] Participation Figure 1-2 As shown in the figure, a portable ring pressing and punching device in this embodiment includes a base 1, a punching mechanism 2 and a ring pressing mechanism 3 mounted on the base 1; characterized in that a gear transmission group 4 is mounted on the base 1, and a drive source 5 and a cam 6 are respectively connected to the gear transmission group 4; the cam 6 is connected to the punching mechanism 2 and drives the punching mechanism 2 and the ring pressing mechanism 3 to move to punch and press the paper simultaneously; the drive source 5 can be a small-structure motor; by using the drive source 5 to drive the gear transmission group 4 to move, and using the gear transmission group 4 to drive the punching mechanism 2 and the ring pressing mechanism 3 to punch and press, the overall size of the ring pressing and punching device can be reduced, and the convenience of handling can be improved.

[0018] Participation Figure 2As shown, the gear transmission assembly 4 includes a motor gear 401 connected to the drive source 5, a first-stage gear 402 meshing with the motor gear 401, a second-stage gear 403 meshing with the first-stage gear 402, a third-stage gear 404 meshing on both sides of the second-stage gear 403, and a fourth-stage gear 405 meshing with the third-stage gear 404 respectively; a transmission shaft 406 is installed between the fourth-stage gear 405 and the cam 6, connecting the fourth-stage gear 405 and the cam 6; the drive source 5 drives the motor gear 401 to rotate. The motor gear 401 drives the first-stage gear 402 to rotate, the first-stage gear 402 drives the second-stage gear 403 to rotate, the second-stage gear 403 drives the third-stage gear 404 to rotate, the third-stage gear 404 drives the fourth-stage gear 405 to rotate, and the fourth-stage gear 405 drives the cam 6 to rotate. The cam 6 drives the punching mechanism 2 and the pressing ring mechanism 2 to move to punch and press rings, thus facilitating the punching and pressing of paper. At the same time, the use of gear transmission group 4 can reduce the overall size of the pressing ring punching device and improve the convenience of handling.

[0019] Participation Figure 3 As shown, it also includes a height adjustment groove 702 disposed on the base 1, a rotating shaft 8 adjustablely installed in the height adjustment groove 702, and several rollers 801 installed on the rotating shaft 8; the height adjustment groove 702 includes a low limit groove 7 and a high limit groove 701, and an adjustment groove 702 connecting the low limit groove 7 and the high limit groove 701; several handles 101 are also installed on the base 1; by using the height adjustment groove 702 to adjust the height of the rollers 801 on the rotating shaft 8, the base 1 can be moved on the table by using the rollers 801 to move the base 1, avoiding direct friction between the base 1 and the table; when the pressure ring punching device is used, the base 1 can be directly attached to the table; by using the handles 101, it is easy to pick up the pressure ring punching device from a distance, improving the convenience of picking up the pressure ring punching device.

[0020] In the process of using this utility model, the drive source 5 drives the motor gear 401 to rotate, the motor gear 401 drives the first-stage gear 402 to rotate, the first-stage gear 402 drives the second-stage gear 403 to rotate, the second-stage gear 403 drives the third-stage gear 404 to rotate, the third-stage gear 404 drives the fourth-stage gear 405 to rotate, the fourth-stage gear 405 drives the cam 6 to rotate, and the cam 6 drives the punching mechanism 2 and the pressing mechanism 2 to move to punch holes and press rings, while punching holes and pressing rings on the paper at the same time;

[0021] When the pressure ring punching device needs to be moved on the table, the rotating shaft 8 is moved along the adjusting groove 702 to the lower limit groove 7, so that the roller 801 on the rotating shaft 8 contacts the table. After the table contacts the roller 801, it will exert an upward force on the roller 801, thereby pushing the rotating shaft 8 to the top of the lower limit groove 7. The base of the pressure ring punching device is separated from the table, and then the pressure ring punching device is pushed to move. The roller 801 rolls and drives the pressure ring punching device to move, avoiding the base 1 from directly rubbing against the table, and preventing damage to the table and the base 1 due to friction.

[0022] When the pressure ring punching device is in use, the rotating shaft 8 is moved along the adjusting groove 702 to the bottom of the high limit groove 701, so that the roller 801 on the rotating shaft 8 is disengaged from the table and the base 1 on the pressure ring punching device is in contact with the table, thereby improving the stability of the pressure ring punching device during use.

[0023] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
