Abstract
Description
Technical Field
[0001] This application relates to the field of stapler technology, and more specifically to a stapler track mechanism and a stapler. Background Technology
[0002] Staplers are frequently used in daily study and office work to bind papers and prevent them from scattering. A typical stapler consists of a top cover, a staple path assembly, and a base. The top cover and the tail end of the staple path assembly are rotatably fixed to the base. The staple path assembly includes the staple path, a pressure plate, and a staple pusher. The staple pusher is positioned in the staple path, restraining the staples and pushing them towards the front end of the path. The pressure plate is rotatably connected to the tail end of the staple path, with its front end aligned with the exit point at the front of the path. When using the stapler, the user presses the top cover, causing the pressure plate to push the staples out of the staple path, completing the binding process. The staple pusher moves along the staple path, pushing the staples forward and preventing them from moving during binding. At this time, the pressure plate presses down, forcing the staples out of the exit point of the staple path.
[0003] However, these traditional staplers have a problem with their staple path design: the distance between the staple exit points is fixed, roughly equal to the width of a staple. Therefore, during use, if there are issues such as blank printing, accidental staple pressing, poor staple insertion, or excessively thick paper, the staples may fail to disengage and become stuck in the exit point. Since the exit point is only the thickness of a staple, the stuck staple will remain firmly in place, hindering subsequent use of the stapler. Furthermore, removing the stuck staple is time-consuming and laborious for the user. Utility Model Content
[0004] The purpose of this application is to provide a stapler track mechanism and a stapler to solve the problem of staple jamming.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A stapler track mechanism is provided, comprising a retracted state and an extended state. The stapler track mechanism includes: a staple sleeve and a stapler assembly, both of which are hollow structures. The stapler assembly is used to hold staples, and the staple placement end of the stapler assembly has a staple outlet. The staple sleeve accommodates the stapler assembly, and the stapler assembly is movably connected to the staple sleeve. A first elastic member is connected to the staple sleeve and is disposed on the staple sleeve at an end away from the staple outlet. When the stapler track mechanism is in the retracted state, the first elastic member abuts against the stapler assembly, and the thickness of the staple outlet corresponds to the thickness of one staple. When the stapler track mechanism is in the extended state, the first elastic member pushes the stapler assembly away, and the thickness of the staple outlet is greater than the thickness of one staple.
[0006] As a preferred embodiment, the staple path assembly includes an inner staple path and an outer staple path. The outer staple path is movably sleeved with the staple sleeve, the staple sleeve accommodates the outer staple path, and the outer staple path accommodates the inner staple path. The inner staple path is movable relative to the outer staple path, and the staple insertion end of the inner staple path and the staple insertion end of the outer staple path form the staple exit opening. When the staple path mechanism is in the retracted state, the first elastic element abuts against the inner staple path, and the staple insertion end of the inner staple path moves closer to the staple insertion end of the outer staple path. At this time, the thickness of the staple exit opening corresponds to the thickness of one staple. When the staple path mechanism is in the extended state, the first elastic element pushes open the inner staple path, and the staple insertion end of the inner staple path moves away from the staple insertion end of the outer staple path. At this time, the thickness of the staple exit opening is greater than the thickness of one staple.
[0007] As another preferred embodiment, the stapler track mechanism further includes: a staple pusher, which is placed between the inner staple track and the outer staple track and is used to engage with the staples and push the staples toward the staple outlet; a connecting rod, one end of which is connected to the staple pusher and the other end of which is connected to the protrusion of the staple sleeve, and a second elastic element is sleeved around the periphery of the connecting rod, one end of which abuts against the staple pusher and the other end of which abuts against the protrusion, and the second elastic element deforms under compression to limit the staples by the staple pusher.
[0008] More preferably, the first elastic element is sleeved on the outer periphery of the second elastic element, and one end of the first elastic element is fixed to the protrusion, and the first elastic element is arranged in the direction of extension of the connecting rod; wherein, when the nail channel mechanism is in the retracted state, the first elastic element deforms and abuts against the inner nail channel.
[0009] Further preferably, the inner diameter of the first elastic member near the protrusion is smaller than the inner diameter of the second elastic member, and the inner diameter of the first elastic member gradually increases along the extension direction of the first elastic member.
[0010] Further preferably, the first elastic element is configured with a conical structure.
[0011] In a further preferred embodiment, the inner nail channel is provided with a baffle, and when the nail channel mechanism is in the retracted state, the baffle abuts against and presses against the first elastic member.
[0012] Further preferably, the outer nail channel is provided with an outer nail channel protrusion, and correspondingly, the inner nail channel is provided with an inner nail channel hole. When the inner nail channel is accommodated within the outer nail channel, the outer nail channel protrusion extends into the inner nail channel hole from below, and the two cooperate with each other. The outer nail channel protrusion slides within the range of the inner nail channel hole along the longitudinal axis of the nail channel assembly, thereby determining the limited range of relative sliding between the inner and outer nail channels.
[0013] Further preferably, the inner nail channel is provided with a flange structure, and correspondingly, the outer nail channel is provided with a snap-fit opening. When the inner nail channel is accommodated in the outer nail channel, the flange structure is embedded in the snap-fit opening, and the flange structure moves within the snap-fit opening along the longitudinal axis of the nail channel assembly.
[0014] This application also provides a stapler, the stapler comprising: a housing body; and a stapler track mechanism as described in any of the above claims, the stapler track mechanism being connected to the housing body.
[0015] Compared with the prior art, the beneficial effects of this application are as follows:
[0016] The stapler mechanism has a retracted state and an extended state, and the thickness of the staple outlet can be adjusted according to different situations. In the retracted state, the staple outlet corresponds to the thickness of one staple, which is suitable for normal use. In the extended state, the staple outlet thickness is increased. In the extended state, the staple outlet thickness increases, and the staples that are stuck in the outlet during normal use can fall out from the thicker outlet by the increased staple outlet thickness, thus avoiding staple jamming and improving the versatility of the stapler.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0027] In a preferred embodiment, see Figures 1 to 5 This application provides a stapler track mechanism 1, which includes a retracted state and an extended state. The stapler track mechanism includes: a staple sleeve 10 and a stapler assembly 20, both of which are hollow structures. The stapler assembly 20 is used to place staples, and the staple placement end of the stapler assembly 20 is provided with a staple outlet 50. The staple sleeve 10 accommodates the stapler assembly 20, and the stapler assembly 20 is movably connected to the staple sleeve 10. A first elastic member 30 is connected to the staple sleeve 10 and is disposed on the staple sleeve 10 at one end away from the staple outlet 50. When the stapler track mechanism is in the retracted state, the first elastic member 30 abuts against the stapler assembly 20, and the thickness of the staple outlet 50 corresponds to the thickness of a staple. When the stapler track mechanism is in the extended state, the first elastic member 30 pushes the stapler assembly 20 away, and the thickness of the staple outlet 50 is greater than the thickness of a staple.
[0028] The first elastic element 30 is a spring structure. The retracted state of the stapler mechanism is the state when the stapler needs to be used. In this state, the stapler assembly 20 is housed in the staple sleeve 10. The staples in the stapler assembly 20 can be pressed by the staple presser plate, pushing the staples out of the staple outlet 50. When a staple needs to be added, the stapler assembly 20 is pushed outward to form the pushed-out state of the stapler mechanism. Correspondingly, the staple outlet 50 in the stapler assembly 20 has two thicknesses. In the retracted state, the thickness of the staple outlet 50 can only accommodate a single staple. However, when the stapler mechanism 1 changes from the retracted state to the pushed-out state, the thickness of the staple outlet 50 gradually increases to a thickness that can accommodate two or more staples, thereby effectively preventing staple jamming.
[0029] As a preferred embodiment, the stapler assembly 20 includes an inner stapler 60 and an outer stapler 70. The outer stapler 70 is movably sleeved with a staple sleeve 10. The staple sleeve 10 accommodates the outer stapler 70, and the outer stapler 70 accommodates the inner stapler 60. The inner stapler 60 is movable relative to the outer stapler 70. The staple placement end of the inner stapler 60 and the staple placement end of the outer stapler 70 form a staple outlet 50. When the stapler mechanism is in the retracted state, the first elastic member 30 abuts against the inner stapler 60, and the staple placement end of the inner stapler 60 moves closer to the staple placement end of the outer stapler 70. At this time, the thickness of the staple outlet 50 corresponds to the thickness of a single staple. When the stapler mechanism is in the extended state, the first elastic member 30 pushes the inner stapler 60 away, and the staple placement end of the inner stapler 60 moves away from the staple placement end of the outer stapler 70. At this time, the thickness of the staple outlet 50 is greater than the thickness of a single staple.
[0030] It should be noted that in the staple path assembly 20, the outer staple path 70 moves relative to the staple sleeve 10, while the inner staple path 60 moves relative to the outer staple path 70. There is a certain gap between the outer wall of the inner staple path 60 and the inner wall of the outer staple path 70 to facilitate staple placement. When the stapler staple path mechanism 1 is in the retracted state, the staple path assembly 20 has two expected directions of movement, see [reference needed]. Figure 2 That is, the first direction X1 and the second direction X2. After the stapler track mechanism 1 is assembled with the stapler, the buckle set on the stapler can prevent the staple track assembly 20 from popping out in the second direction X2. At the same time, the end of the outer staple track 70 abuts against the staple track in a Z-shape, effectively preventing the outer staple track 70 from continuously moving in the first direction X1 and limiting the stroke of the outer staple track 70.
[0031] Meanwhile, since the inner staple path 60 is movable relative to the outer staple path 70, the change in the thickness of the staple outlet 50 is accomplished by the movement of the inner staple path 60 relative to the outer staple path 70. Therefore, when the stapler staple path mechanism 1 is in the retracted state, the inner staple path 60 also needs to be limited and fixed. Thus, a first elastic element 30 is provided to abut against the inner staple path 60. The first elastic element 30 gives the inner staple path 60 a force in the second direction X2, thereby preventing the inner staple path 60 from continuously moving in the first direction X1. As a result, when the stapler staple path mechanism 1 is in the retracted state, the thickness of the staple outlet 50 is prevented from being too large, ensuring that the staple outlet 50 can only allow a single staple to be pressed out.
[0032] Furthermore, when the stapler track mechanism 1 changes from the retracted state to the extended state, the first elastic element 30 can also assist in extending the inner staple track 60, giving the inner staple track 60 a force that extends it in the second direction X2, so as to facilitate the movement of the inner staple track 60.
[0033] As another preferred embodiment, the stapler track mechanism 1 further includes: a staple pusher 80, which is placed between the inner staple track 60 and the outer staple track 70 and is used to conform to the staples and push the staples toward the exit 50; a connecting rod 90, one end of which is connected to the staple pusher 80 and the other end of which is connected to the protrusion 11 of the staple sleeve 10, and a second elastic member 40 is sleeved around the periphery of the connecting rod 90. One end of the second elastic member abuts against the staple pusher 80 and the other end abuts against the protrusion 11. As the second elastic member 40 is squeezed and deformed, the staple pusher 80 is used to limit the staples.
[0034] In a further preferred embodiment, the first elastic element 30 is sleeved on the outer periphery of the second elastic element 40, and one end of the first elastic element 30 is fixed to the protrusion 11, and the first elastic element 30 is arranged in the direction of extension of the connecting rod 90; wherein, when the nailing mechanism is in the retracted state, the first elastic element 30 deforms and abuts against the inner nailing channel 60.
[0035] Further preferably, the inner diameter of the first elastic member 30 near the protrusion 11 is smaller than the inner diameter of the second elastic member 40, and the inner diameter of the first elastic member 30 gradually increases along the extension direction of the first elastic member 30.
[0036] Further optimization involves the first elastic element 30 being configured with a conical structure.
[0037] Further preferably, the inner nail channel 60 is provided with a baffle 61. When the nail channel mechanism is in the retracted state, the baffle 61 abuts against and compresses the first elastic member 30. The baffle 61 facilitates the compression force on the inner nail channel 60. See also... Figure 3 and Figure 4A connecting rod 90 is sandwiched between the baffles 61, which can further improve the stability of the connecting rod 90 during movement. At the same time, the inner diameter of the first elastic member 30 is smaller on the side near the baffle 61. The end of the first elastic member 30 on the side of the baffle 61 is limited and abutted by the second elastic member 40, thereby effectively fixing the first elastic member 30. This allows the first elastic member 30 to be fixed in position relative to the baffle 61 without any rigid connecting parts. When the first elastic member 30 ages or wears out due to long-term use, it can be replaced simply by removing the connecting rod 90 and the second elastic member 40, which is quite convenient.
[0038] Meanwhile, the tapered first elastic element 30 ensures that the elastic element has strong elasticity and increases the rebound effect.
[0039] For further optimization, see [link to relevant documentation]. Figures 3 to 5 The outer nail channel 70 is provided with an outer nail channel protrusion 71, and the corresponding inner nail channel 60 is provided with an inner nail channel hole 62. When the inner nail channel 60 is accommodated in the outer nail channel 70, the outer nail channel protrusion 71 extends into the inner nail channel hole 62 from below, and the two cooperate with each other. The outer nail channel protrusion 71 slides within the range of the inner nail channel hole 62 along the longitudinal axis of the nail channel assembly 20, thereby determining the limited range of relative sliding between the inner nail channel 60 and the outer nail channel 70.
[0040] When the inner staple path 60 and the outer staple path 70 are blocked while moving along the first direction X1, that is, when the stapler staple path mechanism 1 is in the retracted state, the outer staple path protrusion 71 is located at the last end position in the inner staple path hole 62, thereby fixing the position of the inner staple path 60 relative to the outer staple path 70, thereby fixing the thickness of the staple outlet 50 along the axial direction of the stapler staple path mechanism 1, so that the staple outlet 50 can only pass through a single staple at this time.
[0041] Specifically, in this application, there are four outer nail channel protrusions 71 and inner nail channel holes 62. The two outer nail channel protrusions 71 and inner nail channel holes 62 located on opposite sides of the inner nail channel 60 form a group. The nail channel assembly 20 in this application has two groups, which can further improve the stability of the nail channel assembly 20 during the adjustment process.
[0042] In a further preferred embodiment, the inner nail channel 60 is also provided with a flange structure 63, and correspondingly, the outer nail channel 70 is provided with a snap-fit opening 72. When the inner nail channel 60 is accommodated in the outer nail channel 70, the flange structure 63 is embedded in the snap-fit opening 72, and the flange structure 63 moves within the snap-fit opening 72 along the longitudinal axis of the nail channel assembly 20.
[0043] It should be noted that, see Figure 5The flange structure 63 is flipped downwards, so the end of the flange structure 63 is embedded in the locking opening 72. When the stapler track mechanism 1 changes from the retracted state to the pushed-out state, the outer staple track 70 pops out. Therefore, the flange structure 63 provided through the outer staple track 70 abuts against the inner wall of the locking opening 72, thereby bringing out the inner staple track 60 to move. At this time, the thickness of the staple outlet 50 in the pushed-out state is the distance that the flange structure 63 moves against the inner wall of the locking opening 72.
[0044] This application also provides a stapler, which includes: a housing body; and a stapler track mechanism 1 as described in any of the above, wherein the stapler track mechanism 1 is connected to the housing body, and the stapler has the beneficial effects of any of the above, which will not be described in detail here.
[0045] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
