Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.
[0039] Example 1:
[0040] Please refer to Figure 1-6 This embodiment provides a multi-action automatic reset key mechanism, characterized in that it includes a support body 10, and a control component 20 and a key component 30 mounted on the support body 10.
[0041] In this embodiment, the bracket body 10 provides support and a mounting base for the control component 20 and the keypad component 30.
[0042] The control component 20 includes a main control board 21, a trigger 22, and a power supply. The main control board 21 is fixed to the top of the bracket body 10, the trigger 22 is disposed at the bottom of the main control board 21, and the power supply is fixed to one end of the bracket body 10 through a battery mounting seat. The power supply is electrically connected to the main control board 21, and the trigger 22 can be connected to the main control board 21 by means of electrical connection or signal connection.
[0043] The trigger 22 is used to control the start and stop of the fiber clamping function, including but not limited to the following methods: controlling the start and stop of the fiber clamping function by controlling the connection and disconnection between the power supply and the main control board 21; controlling the start and stop of the fiber clamping function of the main control board; starting the fiber clamping function when the main control board 21 detects that the trigger 22 is in a closed state; and stopping or turning off the fiber clamping function when the main control board 21 detects that the trigger 22 is in an open state.
[0044] The key assembly 30 includes a key body 31 and a key slider 32. The key body 31 is connected to the key slider 32 via a connecting seat 39. The key slider 32 is slidably connected to the support body 10 and is positioned close to the trigger 22. The key slider 32 can move back and forth between a first position and a second position. The key body 31 is connected to the key slider 32, and the key body 31 drives the key slider 32 to move on the support body 10. When the key slider 32 slides to the first position, the key slider 32 and the trigger 22 are... In the first connection mode, the power supply component is electrically connected to the main control board 21, or the trigger component 22 is in the first state (the first state can be a closed switch or an open switch). When the toggle slider 32 slides to the second position, the toggle slider 32 and the trigger component 22 are in the second connection mode. In this mode, the power supply component is electrically disconnected from the main control board 21, or the trigger component 22 is in the second state (the second state can be a closed switch or an open switch). This control of the fiber clamp's opening or closing can avoid accidental operation, is simple and labor-saving, and has high reliability.
[0045] Specifically, a key mounting base is formed on the main body 10 of the bracket; the key mounting base has a first limiting plate 11 and a second limiting plate 12, the first limiting plate 11 and the second limiting plate 12 are respectively disposed at both ends of the sliding direction of the key slider 32; the first limiting plate 11 is provided with a first groove and a second groove; the second limiting plate 12 is provided with a first through hole 114 and a second through hole 115; a first channel and a second channel are formed inside the key slider 32.
[0046] The key assembly 30 further includes a first guide rod 33 and a second guide rod 34. The first guide rod 33 passes through the first channel, with one end engaging with the first slot and the other end engaging with the first through hole 114. The second guide rod 34 passes through the second channel, with one end engaging with the second slot and the other end engaging with the second through hole 115. This allows the key slider 32 to slide smoothly within the key mounting base, saving space and ensuring smooth sliding. The first guide rod 33 and the second guide rod 34 are made of metal tubing, which has a smooth surface and high hardness, enabling stable sliding and making it suitable for high-frequency or reciprocating motion scenarios.
[0047] The toggle slider 32 has a stepped portion 323 on its side, which has a concave and a convex part. The trigger 22 is a micro switch with a roller lever. By moving the toggle slider 32 between a first position and a second position, the roller lever contacts the concave or convex part, causing the roller lever to swing, thereby switching the toggle slider 32 and the trigger 22 between a first connection mode and a second connection mode, controlling the on / off state of the power supply unit and the main control board 21 or controlling the start / stop of the fiber clamping function.
[0048] Furthermore, the second limiting plate has a third slot;
[0049] The key assembly 30 also includes a hook 35, one end of which is engaged in the third slot, and the other end forms a downwardly curved hook.
[0050] The toggle slider 32 has a groove, which is adapted to the hook of the hook 35. The groove has a first hook position 324 and a second hook position 325. The hook can pass through or slide in the groove and hook onto the first hook position 324 or the second hook position 325. When the hook is hooked onto the first hook position 324, the toggle slider 32 stops at the first position. When the hook is hooked onto the second hook position 325, the toggle slider 32 stops at the second position.
[0051] The grooved part of this embodiment also includes a first channel 326 and a second channel 327, which are respectively disposed on both sides of the line connecting the first hook position 324 and the second hook position 325.
[0052] The first channel 326 has a channel inlet and a channel outlet at its two ends, respectively. The channel inlet of the first channel 326 is connected to the first latch position 324, and the channel outlet of the first channel 326 at the other end is connected to the second latch position 325.
[0053] The second channel 327 has a channel inlet and a channel outlet at its two ends, respectively. The channel inlet of the second channel 327 is connected to the second hook position 325, and the channel outlet of the second channel 327 at the other end is connected to the first hook position 324.
[0054] The inlets of the first channel 326 and the second channel 327 can both be straight channels, and the outlets of the first channel 326 and the second channel 327 can both be curved channels. When the toggle slider 32 is moved, the hook can smoothly enter the straight channel. Thus, the hook can pass through the first channel 326 and the second channel 327 in sequence, and hook onto the first hook position 324 and the second hook position 325 in turn, so that the toggle slider 32 and the trigger 22 switch alternately between the first connection mode and the second connection mode.
[0055] Furthermore, the toggle assembly 30 of this embodiment also includes a first elastic element 36 and a second elastic element 37, both of which are compression springs. The first elastic element 36 is sleeved around the first guide rod 33, with one end abutting against the toggle slider 32 and the other end abutting against the second limiting plate 12. The second elastic element 37 is sleeved around the second guide rod 34, with one end abutting against the toggle slider 32 and the other end abutting against the second limiting plate 12. The first elastic element 36 and the second elastic element 37 provide an elastic force to drive the hook into the first latch position 324 and / or the second latch position 325.
[0056] It also includes a support slide plate 13, which is slidably connected to the support body 10. One end of the support slide plate 13 is connected to a fiber clamping block 132, and the other end forms a push-pull plate 131, which extends into the key mounting base.
[0057] The push-pull plate 131 is provided with a third through hole and a fourth through hole. The third through hole allows the first guide rod 33 to pass through, and the fourth through hole allows the second guide rod 34 to pass through.
[0058] It also includes a third elastic element 38, which in this embodiment is implemented by a tension spring; one end of the third elastic element 38 is connected to the push-pull plate 131 and the other end is connected to the key slider 32; the third elastic element 38 provides an elastic force that drives the push-pull plate 131 toward the key slider 32.
[0059] During use, when the toggle slider 32 is stopped in the second position, the hook 35 engages with the second latch position 325. Moving the toggle body 31 overcomes the elastic force of the first elastic element 36 and the second elastic element 37, causing the hook 35 to enter the second channel 327 from the straight channel inlet. After the toggle slider 32 slides to its position, it releases. Under the elastic force of the first elastic element 36 and the second elastic element 37, the hook 35 automatically enters the first latch position 324 from the channel outlet of the second channel 327, stopping the toggle slider 32 in the first position. At this time, the micro switch roller arm contacts the protrusion of the step 323, and the power supply is electrically connected to the main control board 21. Alternatively, the micro switch may be closed at this time. The main control board 21 can detect the closed state of the micro switch and execute control (e.g., start automatic reciprocating fiber clamping action) according to the detection result (e.g., closed state). At the same time, the sliding of the key slider 32 causes the third elastic element 38 to stretch and generate elastic deformation. The third elastic element 38 drives the push-pull plate 131 to move closer to the key slider 32, which drives the bracket slide plate 13 to slide and drives the fiber clamping block 132 at the end to move and clamp the optical fiber. Correspondingly, when switching to another state is required after the previous process is completed, the lever body 31 is turned to overcome the elastic force of the first elastic element 36 and the second elastic element 37, causing the hook 35 to enter the first channel 326 from the straight channel inlet. After the lever slider 32 slides into place, it is released. Under the action of the elastic force of the first elastic element 36 and the second elastic element 37, the hook 35 automatically enters the second latch position 325 from the channel outlet of the first channel 326, stopping the lever slider 32 in place. In the second position, the microswitch roller arm contacts the recess of the step portion 323, and the power supply is electrically disconnected from the main control board 21. Alternatively, the microswitch may be disconnected at this time. The main control board 21 can detect the disconnected state of the microswitch and execute control (e.g., shutting down the automatic reciprocating fiber clamping action) based on the detection result (e.g., disconnected state). Simultaneously, the toggle slider 32 pushes the push-pull plate 131 to abut against the first limit plate 11, and the bracket slide plate 13 slides, causing the fiber clamping block 132 at the end to move and unload the optical fiber. The multi-action automatic reset toggle mechanism of this embodiment can trigger multiple actions with one key. The action is simple and effortless. By setting the first elastic element 36 and the second elastic element 37 to elastically lock the position of the toggle slider 32, the reliability is high.

[0062] The fiber clamping assembly 50 involved in this embodiment forms a fiber clamping channel between two relatively arranged fiber clamping structures 132. A reciprocating motor drives one of the fiber clamping structures 132 to move and clamp and bend the optical fiber. This part is known to those skilled in the art and will not be described in detail here.
