[0055] In conventional staplers, the cutting blade is retracted mainly by a pull-back rod, that is, when the cutting blade needs to be retracted, the user needs to manually pull the pull-back rod to retract the cutting blade, which is time-consuming, labor-intensive, and inconvenient to operate.

[0056] In order to solve the above-mentioned problem, the embodiment of the present application provides a stapler handle component and a stapler, which can save time and effort in the process of retracting the cutting knife and facilitate operation.

[0057] Please refer to Figures 1 to 6 , Figure 1 is a schematic structural diagram of a stapler handle component 100 in one embodiment of the present application. Figure 2 yes Figure 1 The exploded structural diagram of the stapler handle component 100 is shown.

Figure 4 yes Figure 1 The cross-sectional view of the stapler handle component 100 along the MM direction is shown. Figure 5 yes Figure 1 The internal structure diagram of the stapler handle component 100 is shown in FIG. Figure 6 yes Figure 5 A schematic diagram of the internal structure of the stapler handle component 100 from another perspective is shown.

[0058] In the first aspect, the present application provides a stapler handle component 100, comprising a housing 10, a first moving member 20, a second moving member 30, a synchronous transmission member 40, a trigger assembly 50, and an adjustment assembly 60. The first moving member 20 is movably disposed in the housing 10; the second moving member 30 is movably disposed in the housing 10, and one of the first moving member 20 and the second moving member 30 is used to connect with a cutting knife (not shown in the figure).

[0061] It is understandable that, since the first moving member 20 and the second moving member 30 are both connected to the synchronous transmission member 40, so that the first moving member 20 and the second moving member 30 move synchronously, and the moving directions of the first moving member 20 and the second moving member 30 are opposite, when the trigger assembly 50 drives the first moving member 20 to move in the first direction, the second moving member 30 will move synchronously in the second direction, and the second direction is the opposite direction of the first direction.

[0062] The adjusting assembly 60 is connected to the second movable member 30 , and the adjusting assembly 60 can drive the second movable member 30 to move toward the direction close to the trigger assembly 50 , so that the trigger assembly 50 is transmission-connected to the second movable member 30 , and at the same time, the trigger assembly 50 is disconnected from the first movable member 20 .

[0063] It is understandable that, since the adjustment assembly 60 can drive the second moving member 30 to move in the direction close to the trigger assembly 50, the second moving member 30 is closer to the trigger assembly 50, so that the trigger assembly 50 can be connected to the second moving member 30 in a transmission manner, and at the same time, the trigger assembly 50 is disconnected from the first moving member 20. The adjustment assembly 60 can also drive the second moving member 30 to move in the direction away from the trigger assembly 50, so that the trigger assembly 50 is disconnected from the second moving member 30, and at the same time, the trigger assembly 50 is reconnected to the first moving member 20 in a transmission manner.

[0064] Please refer to Figure 7 , Figure 8 and Fig. 9 , Figure 7 Yes Figure 5 The schematic diagram of the first moving member 20 of the stapler handle component 100 after moving along the first direction is shown. Figure 8 Yes Figure 4 The schematic diagram of the first moving member 20 of the stapler handle component 100 after moving along the first direction is shown. Fig. 9 Yes Figure 7 The diagram shown is a schematic diagram of the second movable member 30 of the stapler handle component 100 after it moves toward the direction close to the trigger assembly 50.

[0065] In this embodiment, when the cutting knife is advanced, the first movable member 20 connected to the cutting knife can be driven by the trigger assembly 50 to move in the first direction, and the second movable member 30 can be driven to move in the direction opposite to the first direction to advance the cutting knife; when the cutting knife needs to be retracted, it is only necessary to drive the second movable member 30 to move in the direction close to the trigger assembly 50 through the adjusting assembly 60, so that the trigger assembly 50 is transmission-connected to the second movable member 30, and at the same time, the trigger assembly 50 is disconnected from the first movable member 20, and the second movable member 30 can be driven by the trigger assembly 50 to move in the first direction, and the first movable member 20 can be driven to move in the direction opposite to the first direction.

[0066] It is understandable that in other embodiments, if the second movable member 30 is connected to the cutting knife, when the cutting knife is advanced, it is only necessary to drive the second movable member 30 to move in the direction close to the trigger assembly 50 through the adjusting assembly 60, so that the trigger assembly 50 is transmission-connected with the second movable member 30, and at the same time, the trigger assembly 50 is disconnected from the first movable member 20, and the second movable member 30 can be driven by the trigger assembly 50 to move in the first direction, and the first movable member 20 can be driven to move in the direction opposite to the first direction; when it is necessary to retract the cutting knife, it is only necessary to drive the second movable member 30 to move in the direction away from the trigger assembly 50 (ultimately limited by the housing 10) through the adjusting assembly 60, so that the trigger assembly 50 is disconnected from the second movable member 30, and at the same time, the trigger assembly 50 is transmission-connected with the first movable member 20, and the first movable member 20 can be driven by the trigger assembly 50 to move in the first direction, and the second movable member 30 can be driven to move in the second direction.

[0067] It should be noted that the adjustment component 60 can be a cylinder, a hydraulic cylinder or a linear module.

Move so that the trigger assembly 50 is transmission connected with the second movable member 30, and at the same time, the trigger assembly 50 is disconnected from the first movable member 20. Therefore, when realizing the switching of the forward and retracting of the cutting knife, it is only necessary to adjust the position of the second movable member 30 through the adjustment assembly 60, so that one of the first movable member 20 and the second movable member 30 is transmission connected with the trigger assembly 50, and the other of the first movable member 20 and the second movable member 30 is disconnected from the trigger assembly 50. That is, the handle component provided in the embodiment of the present application can be driven by the trigger assembly 50 when realizing the advancement and retraction of the cutting knife. The operator can operate it with one hand, and the operation is simple and convenient, saving time and effort.

[0069] Please refer to Fig.10 , Fig.10 yes Figure 2 The schematic diagram of the structure of the first moving member 20, the second moving member 30 and the adjusting assembly 60 is shown.

[0072] In this embodiment, the synchronous transmission member 40 includes a synchronous gear located between the first moving member 20 and the second moving member 30, and the synchronous teeth 41 are arranged on the synchronous gear.

[0073] It can be understood that the synchronous gear is rotatably disposed in the housing 10 .

[0074] In other embodiments, the synchronous transmission member 40 includes at least two synchronous pulleys (not shown in the figure) and a synchronous belt (not shown in the figure) wound around the synchronous pulleys, the first moving member 20 and the second moving member 30 are respectively arranged on both sides of the synchronous belt, and the synchronous teeth 41 are arranged on the synchronous belt. In this way, the first moving member 20 and the second moving member 30 can be synchronized and move in opposite directions.

[0075] Please refer to Fig.11 , Fig.11 yes Figure 2 An exploded structural view of the trigger assembly 50 is shown.

[0078] Specifically, the first drive tooth set 22 includes a plurality of first ratchet teeth (not shown), and the power drive member 51 includes a driving pawl matched with the first ratchet teeth. In this way, the driving pawl can be matched with different first ratchet teeth in sequence to drive the first moving member 20 to move in the first direction.

[0079] Similarly, the second driving teeth group 32 includes a plurality of second ratchets (not shown), and the second ratchets cooperate with the driving pawl. In this way, the driving pawl can be matched with different second ratchets in sequence to drive the second moving member 30 to move in the first direction.

[0080] In this embodiment, the trigger assembly 50 further includes a trigger 52, a driving elastic member 53, a reset elastic member 54 and a connecting pin 55, the trigger 52 is rotatably connected to the housing 10 via the connecting pin 55, the driving claw is provided on the trigger 52, the driving elastic member 53 abuts against the driving claw, so that the driving claw rotates relative to the trigger 52 to be transmission-connected with the first moving member 20, and the reset elastic member 54 is connected to the trigger 52, so that the trigger 52 rotates relative to the housing 10 and the driving claw moves along the second direction.

[0081] Among them, when the trigger 52 is fully engaged and then released, the trigger 52 is automatically reset under the action of the reset elastic member 54, and the driving claw is automatically lower than the first ratchet under the action of the trigger 52 driving elastic member 53, and will retreat to the proximal end to prepare for the next firing; finally, the cutting knife at the jaws of the stapler is limited at the distal end, and then the trigger 52 at the handle end will also be unable to be pulled.

[0082] Please refer to Figure 2 , Figure 3 and Fig.10 Optionally, the handle component also includes a slide rail component 70 connected to the adjustment assembly 60, the slide rail component 70 can be movably arranged in the shell 10, and the moving direction of the slide rail component 70 is set at an angle to the moving direction of the first movable component 20, and the second movable component 30 is slidably connected to the slide rail component 70.

[0083] By adopting the above solution, the second movable member 30 can move in the first direction and the second direction, and the adjusting assembly 60 can also drive the second movable member 30 to move in a direction close to the trigger assembly 50 .

[0084] It can be understood that the moving direction of the slide member 70 is the direction close to the trigger assembly 50, that is, the adjustment assembly 60 can drive the slide member 70 and the second movable member 30 to move together in the direction close to the trigger assembly 50, and the second movable member 30 can move along the first direction and the second direction relative to the slide member 70.

Such a configuration can not only enable the second moving member 30 to move in the first direction and the second direction, but also enable the adjustment assembly 60 to drive the second moving member 30 to move in a direction close to the trigger assembly 50, and avoid the second moving member 30 from being disconnected from the slide rail member 70.

[0087] By adopting the above solution, the adjusting driving member 62 can be driven to control the slide rail member 70 and the second moving member 30 to move together in a direction close to the trigger assembly 50 , so that the second moving member 30 is in transmission connection with the trigger assembly 50 .

[0088] The adjusting driving member 62 may be a knob, and the operator may use the index finger to turn the adjusting driving member 62 to control the movement of the slide rail member 70 , thereby making the second moving member 30 transmission-connected with the trigger assembly 50 .

[0089] Specifically, the adjusting transmission member 61 is rotatably connected to the housing 10, and the adjusting transmission member 61 is rotatably connected to the slide rail member 70 and the two are threadedly matched. Such an arrangement can make the structure of the adjusting assembly 60 relatively simple, and the slide rail member 70 can be controlled to move by rotating the adjusting transmission member 61, so that the second moving member 30 is transmission-connected to the trigger assembly 50.

[0090] The adjusting transmission member 61 may be a stud or a lead screw, and the adjusting transmission member 61 may be rotatably connected to the housing 10 via a bearing 63, or a hole is provided in the housing 10, and the adjusting transmission member 61 is rotatably inserted into the hole.
