The terminology is for the purpose of describing the invention only and is not intended to be limiting of the invention since it is not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation. Moreover, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1 to 5, which are embodiments of a printer according to the present invention, a printer 100 includes: the movement is arranged in the shell 10, a shifting lever 21 for opening the movement extends out of the movement, the movement is provided with a fixed core and a movable core, and the movable core can be opened by pushing the shifting lever 21. In order to transmit the driving force to the driving lever 21, a push button 30 and a transmission gear 40 are arranged, the push button 30 is telescopically arranged in the shell 10, and when the push button 30 is pressed, the push button 30 moves linearly; the transmission gear 40 is arranged between the push button 30 and the shift lever 21, and the transmission gear 40 is used for transmitting the force on the push button 30 to the shift lever 21 and realizing the opening of the movable core. By arranging the telescopic key 30 and the transmission gear 40, the linear motion is converted into the rotary motion, and the key 30 is connected with the transmission gear 40 through meshing of teeth, so that the transmission is stable; and in the transmission process, the force cannot be decomposed, so that the pushing force required to act on the key 30 is small, which is beneficial to the opening operation of the printer; the transmission structure is simple, the movement fault is reduced, and the manufacturing cost is reduced. When the movement needs to be opened, the push button moves backwards, so that the transmission gear 40 rotates, and the shift lever 21 is pushed to rotate, so that the movement is opened.

Referring to fig. 2, the transmission gear 40 has a first gear 41 and a second gear 42, the first gear 41 is engaged with the push button 30, and the force on the push button 30 is transmitted to the first gear 41; the first gear 41 and the second gear 42 are engaged for transmitting the force on the first gear 41 to the second gear 42; a further second gear wheel 42 transmits the force to the shift lever 21. A rack 31 matched with the first gear 41 is arranged on the key 30, and the rack 31 is meshed with the first gear 41; the force is transmitted from the key 30 to the second gear 42 by adopting the meshing of the teeth, so that the force transmission is smooth in the opening process of the movement, and the waste of force decomposition is avoided. The rack 31 is arranged in the extending and retracting direction of the push button 30, and when the push button 30 is pushed to move backwards or the push button 30 moves forwards again, the rack 31 drives the first gear 41 to rotate.

The radial dimension of the first gear 41 is larger than the radial dimension of the second gear 42, that is, the meshing radius of the first gear 41 is larger than that of the second gear 42, which is beneficial for the second gear 42 to provide a larger pushing force to the shift lever 21.

Referring to fig. 3 and 4, the second gear 42 has a second gear body 421, an extension rod 422 extending outward along the second gear body 421, and a push rod 423, the push rod 423 being used to push the shift lever 21, the push rod 423 being in contact with the shift lever 21. The pushing rod 423 extending toward the shift lever 21 is bent along the extension rod 422. The extension rod 422 and the second gear body 421 are arranged in the same plane, and the pushing rod 423 is arranged perpendicular to the extension rod 422. By providing the extension rod 422 and the pushing rod 423, the approach to the direction of the shift lever 21 is facilitated, so that the pushing rod 423 is in contact with the shift lever 21, which is beneficial to the spatial arrangement of parts. Because the extension rod 422 extends outwards along the second gear body 421 and the push button 30 moves in a reciprocating linear manner, the second gear 42 is preferably half-gear, which facilitates the simple structure of the second gear 42. The first gear 41 is an all-gear.

In this embodiment, the transmission gear 40 is rotatably disposed on the housing 10, that is, the first gear 41 and the second gear 42 are fixed on the housing 10 through a rotating shaft. The printer further includes a paper compartment cover 50 disposed on the housing 10 and capable of being opened and closed, wherein the paper compartment cover 50 is fixedly disposed with the movable core, that is, when the movable core is opened, the paper compartment cover 50 is driven to be opened together. In order to facilitate pressing the key 30, a through hole for the key 30 to pass through is opened on the housing 10, so that the key 30 protrudes from the front end surface of the housing 10 to facilitate the pressing operation.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
