[0024] The pawl body of pawl assembly 8 and the inner wall of inner ratchet wheel 6 slide against each other, rack 10 and gear 9 are engagedly connected, so that when rack 10 moves, it can drive gear 9 to rotate.

[0025] In this embodiment: when printing is needed, in order to improve interactivity and playability, the user first presses the handle 14, which drives the support plate 15 to move, the support plate 15 drives the rack 10 to move downward, the rack 10 drives the gear 9 to rotate, the gear 9 drives the inner ratchet 6 to rotate clockwise, and then the teeth of the inner ratchet 6 are in abutment with the side wall of the pawl body of the pawl assembly 8, thereby driving the pawl assembly 8 to rotate, the pawl assembly 8 drives the driven shaft 7 to rotate, and then the driven shaft 7 drives the rotating shaft 5 to rotate counterclockwise, and (as Figure 5 ) the rack 10 drives the gear 9 to rotate counterclockwise, and then the rotating shaft 5 rotates clockwise, and the rotating shaft 5 can drive the printing paper 4 to move, so that one end of the printing paper 4 moves outward from the printer shell 1, thereby enhancing the interaction and user experience during the printing process of the entire device. When the printing is completed, the handle 14 is moved again to reset the rack 10, and due to the interaction between the inner ratchet 6 and the pawl assembly 8, when the rack 10 is reset, the pawl body in the pawl assembly 8 is in abutment with the side wall of the inner ratchet 6, which will rotate and contract, and then the inner ratchet 6 rotates, and the driven shaft 7 does not rotate, and then the rotating shaft 5 does not drive the printing paper 4 to contract. Figure 4

[0026] Thus, during the use of the printer, the user can intuitively control the output amount of the printing paper, the entire operation process is intuitive and simple, the feedback is timely, and the traditional "black box operation" feeling of the traditional printer is eliminated, and the user's participation in the printing process is significantly enhanced. Compared with traditional button type or automatic paper output type printers, the printer emphasizes the user's own dominance more, gives the user active control over the printing process, and the user is no longer passive waiting for the printing result, but can actively participate in the printing process, thereby obtaining more interesting and personalized experiences.

[0027] Embodiment two: this embodiment is an improvement based on embodiment one, and details are described in Figure 3 Figure 5 The printer shell 1 side wall is provided with a limiting slot 11, the limiting slot 11 inner wall is in abutment and sliding connection with a sliding block 12, the sliding block 12 side wall is fixedly connected with the short plate and the rack 10 side wall, and then the movement track of the rack 10 is limited, so that the rack 10 will not deviate.

[0028] The printer shell 1 side wall is provided with a reset slot 16, the reset slot 16 inner wall is in sliding connection with a reset block 17, the reset block 17 side wall is fixedly connected with the support plate 15 side wall, the reset slot 16 inner wall is fixedly connected with a spring 18, one end of the spring 18 away from the reset slot 16 bottom wall is fixedly connected with the reset block 17 side wall, and the spring 18 can drive the support plate 15 to automatically reset, thereby eliminating the need for manual resetting by the user.

[0029] ​​The first sensor 19 is fixedly connected to the side wall of the printer shell 1, and the second sensor 20 is fixedly connected to the side wall of the supporting plate 15. In the initial state, the first sensor 19 and the second sensor 20 are in mutual induction, at which time two generated signals are fed back to the control center of the printer, and then the printing process cannot be normally carried out. In the process of moving the supporting plate 15, the first sensor 19 and the second sensor 20 are disconnected for a period of time, and then the printing is automatically carried out.

[0030] In the embodiment: in the printing process, the supporting plate 15 and the rack 10 are in a suspended state, and in order to enhance the stability of the entire operation process, the supporting plate 15 and the rack 10 need to be limited. The sliding block 12 slides in the limiting groove 11, and the limiting groove 11 limits the movement of the sliding block 12 in the vertical direction. When the rack 10 moves with the side wall of the supporting plate 15, the rack 10 drives the sliding block 12 to move, and the sliding block 12 limits the movement track of the rack 10, so that the rack 10 does not deviate during movement. The supporting plate 15 also drives the reset block 17 to move and compresses the spring 18. The reset block 17 also limits the movement track of the supporting plate 15. When the supporting plate 15 needs to be reset, the supporting plate 15 is automatically reset under the elastic action of the spring 18, so that the user does not need to manually reset. In the initial state, the first sensor 19 and the second sensor 20 are in mutual induction, at which time two generated signals are fed back to the control center of the printer, and then the printing process cannot be normally carried out. In the process of moving the supporting plate 15, the first sensor 19 and the second sensor 20 are disconnected for a period of time, and then the printing is automatically carried out.

[0031] Working principle: when printing is needed, the user first presses the handle 14, which drives the supporting plate 15 to move, and the supporting plate 15 drives the rack 10, the reset block 17 and the second sensor 20 to move downward. The rack 10 drives the gear 9 to rotate and drives the sliding block 12 to move in the limiting groove 11. The gear 9 drives the inner ratchet wheel 6 to rotate clockwise, and the teeth of the inner ratchet wheel 6 abut against the side wall of the pawl body of the pawl assembly 8, thereby driving the pawl assembly 8 to rotate. The pawl assembly 8 drives the driven shaft 7 to rotate, and the driven shaft 7 drives the rotating shaft 5 to rotate counterclockwise. Figure 5 ) clockwise, and the teeth of the inner ratchet wheel 6 abut against the side wall of the pawl body of the pawl assembly 8, thereby driving the pawl assembly 8 to rotate. The pawl assembly 8 drives the driven shaft 7 to rotate, and the driven shaft 7 drives the rotating shaft 5 to rotate counterclockwise. Figure 4When the rack 10 drives the gear 9 to rotate, the gear 9 rotates counterclockwise, and the rotating shaft 5 rotates clockwise, and the rotating shaft 5 drives the printing paper 4 to move, so that one end of the printing paper 4 moves out of the printer shell 1, and the reset block 17 moves in the reset slot 16 and compresses the spring 18, when the printing is completed, the handle 14 is moved again, the supporting plate 15 is reset under the elastic action of the spring 18, and the rack 10 is reset, at this time, the second inductor 20 is reset, and due to the interaction of the inner ratchet wheel 6 and the pawl assembly 8, when the rack 10 is reset, the pawl body in the pawl assembly 8 is in abutment with the side wall of the inner ratchet wheel 6, and is rotated and retracted, and the inner ratchet wheel 6 rotates, and the driven shaft 7 does not rotate, and the rotating shaft 5 does not drive the printing paper 4 to retract.

[0032] Further, the manual pull rod operation mode of the printer can enable the user to more sensitively capture the working state of the printer. For example, when the paper is about to run out, the user can realize that the paper needs to be replaced through the subtle change of the pull rod resistance or the direct paperless output. This quick and intuitive working state display further improves the convenience and experience of the user.

[0033] Especially for the application of printing music information, the manual pull rod operation mode is similar to the performance of a pull-playing musical instrument such as an accordion, an organ, etc. in music performance. This operation mode is naturally compatible with the music theme, and can further improve the user's experience.

[0034] The contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0035] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
