However, during the punching process, the penetrated paper fragments sometimes enter the interior of the punching syringe. These paper fragments gradually accumulate inside the punching syringe, resulting in reduced operating efficiency of the punching syringe and even possible malfunctions such as paper jams and blockages, thereby affecting the smooth progress of the entire punching process. Therefore, in order to facilitate user use, this device is designed with a punching device that can automatically clean up paper fragments. Utility Model Content

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] Refer to the attached Figure 1-6 The present invention proposes a punching device for filing, comprising a bracket 10, a pressing handle 11 being rotatably mounted on the top of the bracket 10, a pressing cylinder 12 being movably mounted on the bracket 10, an outer sleeve of the pressing cylinder 12 being provided with a spring 13, the top end of the spring 13 being fixedly connected to the outer wall of the pressing cylinder 12, the bottom end of the spring 13 being fixedly connected to the bracket 10, a punching needle cylinder 14 being mounted on the bottom end of the spring 13, a punching platform 15 being mounted on the bracket 10, a punching slot 16 being provided on the outer wall of the punching platform 15 just below the pressing cylinder 12; wherein, the present invention does not improve the principle of punching of the punching device, and when punching, it still presses the pressing handle 11 first, the pressing handle 11 presses the pressing cylinder 12, the pressing cylinder 12 presses the punching needle cylinder 14, and finally the file paper is punched with a hole by the punching needle cylinder 14. The following mainly describes the improved part, and the punching principle thereof is not described in detail;

[0025] A through groove 121 is provided on the side wall of the pressing cylinder 12 and is connected to the interior of the pressing cylinder 12. A cleaning rod 20 is installed on the bracket 10. The cleaning rod 20 moves through the interior of the through groove 121 and extends to the interior of the punching syringe 14. The through groove 121 is provided on the side wall of the pressing cylinder 12 to provide space for the cleaning rod 20 to move. In addition, when the punching syringe 14 is pressed to the bottom, the cleaning rod 20 can be completely in the through groove 121, which is convenient for removing the cleaning rod 20 later.

[0026] When the punching syringe 14 is in the natural state, the bottom end of the cleaning rod 20 is flush with the bottom end of the punching syringe 14; wherein, when the pressing cylinder 12 is in the natural state, the position of the punching syringe 14 no longer changes, and the bottom end of the cleaning rod 20 is flush with the bottom end of the punching syringe 14, so as to better discharge the shredded paper in the punching syringe 14.

[0027] A limit block 24 is fixedly installed on the side wall of the pressing cylinder 12; wherein, the position of the pressing cylinder 12 can be limited by the set limit block 24 to prevent the cleaning rod 20 from moving out of the punching needle cylinder 14.

[0028] A fixing frame 22 is fixedly mounted on the outer wall of the bracket 10, and a fixing plate 21 is fixedly mounted on the top wall of the cleaning rod 20. The fixing plate 21 is clamped to the inside of the fixing frame 22, and a second locking screw 23 is threadedly connected to the outer wall of the fixing frame 22. The second locking screw 23 is used to lock and fix the fixing plate 21; wherein, the cleaning rod 20 can be disassembled here. When disassembling, the second locking screw 23 can be rotated counterclockwise to release the fixation of the second locking screw 23 on the fixing plate 21, and then the fixing plate 21 can be taken out of the fixing frame 22, and the cleaning rod 20 can be disassembled.

[0029] The top end of the punching syringe 14 is inserted into the interior of the pressing cylinder 12, and the outer wall of the pressing cylinder 12 is threadedly connected to the first locking screw 141, which is used to lock and fix the punching syringe 14; wherein, the punching syringe 14 can be disassembled here. When disassembling the punching syringe 14, the first locking screw 141 can be rotated counterclockwise to release the fixation of the first locking screw 141 to the punching syringe 14, and then the punching syringe 14 can be taken out from the pressing cylinder 12.

[0030] A limiting rod 122 is fixedly installed on the outer wall of the bracket 10, and the end of the limiting rod 122 is movably inserted into the inside of the through groove 121; wherein, the setting of the limiting rod 122 can limit the movement of the pressing cylinder 12, thereby improving the stability of the movement of the pressing cylinder 12.

[0031] In this embodiment, the working principle of the device is as follows: after the punching syringe 14 completes the punching action, the pressing handle 11 is lifted up, and under the elastic potential energy of the spring 13, the pressing cylinder 12 drives the punching syringe 14 to move upward. During the upward movement of the punching syringe 14, the cleaning rod 20 enters the interior of the punching syringe 14 and pushes out the shredded paper inside the punching syringe 14, thereby completing the cleaning;

[0032] The cleaning mechanism can automatically clean the inside of the punching syringe 14 while the punching syringe is reset, thereby preventing paper fragments from remaining inside the punching syringe 14, thereby improving the efficiency of subsequent punching and the practicality of the device.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
