Furthermore, the transmission rates of optical modules are constantly increasing as optical communication technology evolves. Utility Model Content

[0003] Some embodiments provide an optical module to facilitate unlocking the optical module from a host computer cage.

[0004] Some embodiments provide an optical module, including:

[0005] The shell has an accommodating groove formed on the outer side;

[0006] Unlock components, including:

[0007] A first cantilever, assembled and connected to the outer wall of one side of the shell, with a first engaging portion formed at the end thereof;

[0008] A second cantilever, assembled and connected to the outer wall of the other side of the shell, with a second engaging portion formed at the end thereof;

[0010] a gripping portion connecting the first cantilever and the second cantilever;

[0011] An elastic member is disposed in the accommodating groove; the elastic member comprises:

[0012] a receiving portion, one end of which is close to the first cantilever and the other end of which is close to the first cantilever; the receiving portion is located below the bridging body and on the side of the reset body;

[0013] a first elastic portion, obliquely disposed on one side of the receiving portion, connected to one end of the receiving portion; the other end of the first elastic portion is closer to the receiving portion than the one end of the first elastic portion;

[0014] The second elastic portion is obliquely arranged on one side of the receiving portion and connected to the other end of the receiving portion; one end of the second elastic portion is closer to the receiving portion than one end of the second elastic portion.

[0015] One of the above technical solutions has the following advantages or beneficial effects: the unlocking component includes a first cantilever, a second cantilever, a bridge portion, a holding portion, and an elastic member. The outer side of the shell forms a receiving groove, and the elastic member is arranged in the receiving groove. The first cantilever is arranged on the outer wall of one side of the shell, the second cantilever is arranged on the outer wall of the other side of the shell, and the bridge portion connects the first cantilever and the second cantilever. The bridge portion includes a bridge body and a reset body, the bridge body covers the receiving groove to encapsulate the elastic member in the receiving groove, effectively reducing the elastic member jumping out of the receiving groove. The holding portion connects the first cantilever and the second cantilever, facilitating the pulling of the first cantilever and the second cantilever through the holding portion.

[0016] The elastic member includes a receiving portion, a first elastic portion, and a second elastic portion. The receiving portion is arranged along the width direction of the shell, and the first elastic portion and the second elastic portion are both arranged obliquely on one side of the receiving portion, with the receiving portion being on the other side of the reset body.

The other end of the first elastic portion and the other end of the second elastic portion are closer to the receiving portion, so that the elastic member has elasticity. When the holding portion is pulled with force, the receiving portion will be subjected to leftward pressure, causing the receiving portion to move leftward to deviate from its initial position.

[0086] Some embodiments of the present disclosure will be described in detail with reference to the drawings, whereupon the embodiments described are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0087] Unless the context clearly requires otherwise, throughout the description and the claims, the term "comprise", and variations thereof (such as "comprises" and "comprising"), will be construed to be inclusive, that is to say, "including but not limited to", and the terms "first", "second", etc. will not be construed as indicating or implying relative importance or indicating the number of steps of the disclosed implementation. The term "plurality" means two or more. The term "connected" should be interpreted broadly, for example, "connected" can be fixed connection, or detachable connection, or integral, can be directly connected, or indirectly connected through an intermediate medium. The use of the terms "adapted to" or "configured to" means open and inclusive language, which does not exclude devices adapted or configured to perform additional tasks or steps. The terms "parallel", "vertical", "same", "consistent", "flush" and the like are not limited to absolute mathematical relationships, but also include acceptable error ranges generated in practice, and differences based on the same design concept but due to manufacturing reasons.

[0088] In optical communication technology, in order to establish information transmission between information processing devices, information is loaded onto light, and the transmission of information is carried out by using the propagation speed of light. Such information-loaded light is an optical signal. The optical signal can reduce the loss of optical power when transmitted in an optical information transmission device, and realize long-distance transmission of the optical signal. At the same time, the cost of optical information transmission devices such as optical fibers is lower than that of electrical information transmission devices such as copper wires. Therefore, optical communication technology can realize high-speed, long-distance, and low-cost information transmission.

[0089] Information processing devices generally include optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, and the like. Optical information transmission devices generally include optical fibers and optical waveguides. The signals that information processing devices can recognize and process are electrical signals, while optical communication technology uses optical signals for transmission, which requires optical modules to convert optical signals and electrical signals.

[0090] Optical modules can realize the mutual conversion of optical signals and electrical signals between information processing devices and optical information transmission devices. In some embodiments, at least one of the optical signal input end or the optical signal output end of the optical module is connected with an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected with an optical network unit; a first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network unit; a second electrical signal from the optical network unit is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber.

[0091] Since information can be transmitted between multiple information processing devices through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, without all the information processing devices being directly connected to the optical module. Here, the information processing device directly connected to the optical module is also referred to as the host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module is referred to as the optical port, and the electrical signal input end or the electrical signal output end of the optical module is referred to as the electrical port.

[0092] Figure 12C FIG. 1 is a schematic diagram of a part of an optical communication system according to some embodiments. As shown in FIG. 1, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100 of an optical module, an optical module 200, an optical fiber 101, and a network cable 103, wherein the optical fiber 101 belongs to an optical information transmission device, and the network cable 103 belongs to an electrical information transmission device.

The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can maintain the original optical power. The optical signal is totally reflected multiple times in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance information transmission based on low power loss.

[0094] The optical communication system includes one or more optical fibers 101. In some embodiments, the optical fiber 101 is detachably connected to the optical module 200; in some embodiments, the optical fiber 101 is non-detachably connected to the optical module 200.

[0095] The host computer 100 is configured to provide a data signal to the optical module 200, or receive a data signal from the optical module 200, or monitor or control the working state of the optical module 200.

[0096] The host computer 100 includes a housing accommodating the optical module 200, and an optical module interface 102 disposed on the housing. The optical module 200 is inserted into the housing through the optical module interface 102, so that the host computer 100 and the optical module 200 establish a one-way or two-way electrical signal connection.

[0097] ​The host computer 100 further comprises an external electrical interface which can access a telecommunication network. In some embodiments, the external electrical interface comprises a Universal Serial Bus (USB) or a network cable interface 104. The network cable interface 104 is configured to access a network cable 103 to enable the host computer 100 to establish a unidirectional or bidirectional electrical signal connection with the network cable 103.

[0098] One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100 to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. In some embodiments, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal.

For example, the upper side plate 2012 can be located inside the lower side plate 2022.

[0114] As shown in Figure 3 In some embodiments, the optical module includes a fiber adapter 700 located at the opening 204, and the fiber adapter 700 is used to connect the optical fiber 101. For example, the fiber adapter 700 can be connected to the optical fiber 101 in a plug-in manner or in a fixed manner.

[0115] In some embodiments, the fiber adapter 700 is connected to the light emitting component 400 or the light receiving component 500 through a fiber ribbon. The fiber adapter 700 is used to realize the butt joint of the fiber ribbon and the optical fiber 101.

The chips can include microcontroller units (MCUs), laser drive chips, transimpedance amplifiers (TIAs), limiting amplifiers (LAs), clock and data recovery chips (CDRs), power management chips, digital signal processing (DSP) chips.

[0117] In some embodiments, the circuit board includes a rigid circuit board, which due to its relatively hard material, can also realize a bearing function, such as the rigid circuit board can stably bear the above-mentioned electronic components and chips; the rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0118] In some embodiments, the circuit board further includes a flexible circuit board, which can be used independently; or can be used in cooperation with the rigid circuit board.

[0119] In some embodiments, the circuit board further includes a gold finger 301 formed on the surface of the end thereof, the gold finger 301 being composed of a plurality of pins independent of each other.

[0120] In some embodiments, the gold finger 301 is disposed on the surface of one side of the circuit board 300 (for example Figure 3 the upper surface as shown); in some embodiments, the gold finger 301 is disposed on the surfaces of the upper and lower sides of the circuit board 300 to provide a larger number of pins to adapt to occasions requiring a large number of pins.

[0121] In some embodiments, the gold finger of the circuit board extends from the electrical port and is inserted into the electrical connector of the host computer 100; the circuit board is inserted into the cage 106, and the gold finger 301 is in conduction with the electrical connector in the cage 106.

When the light module 200 is inserted into the cage 106, the light module 200 is fixed in the cage 106 by the clamping component of the unlocking component 600; when the unlocking component 600 is pulled, the clamping component of the unlocking component 600 moves accordingly, thereby changing the connection relationship of the clamping component with the host machine, to release the fixation of the light module 200 with the host machine, so that the light module 200 can be pulled out of the cage 106.

[0124] In some embodiments, the light emitting component 400 and the light receiving component 500 can be physically separated from the circuit board 300 respectively, and then be electrically connected with the circuit board 300 through corresponding flexible circuit boards or electrical connectors respectively.

[0127] Figure 4 An assembly view of an unlocking component and a shell according to some embodiments is shown. Figure 4 An exploded view of an unlocking component and a shell according to some embodiments is shown. Figure 5A , Figure 5B An exploded view of an unlocking component and a shell according to some embodiments is shown. Figure 1 . An assembly view of an unlocking component and a shell is shown. Figure 5C An assembly view of an unlocking component and a shell is shown.

[0128] As Figure 2As shown, in some embodiments, the unlocking component 600 can include a first cantilever 610, which can be located on the outer side of the lower side plate 2022. An end of the first cantilever 610 is formed with a first clamping portion 611, which clamps the cage 106, and thus can fix the optical module 200 in the cage 106. Exemplarily, the inner side of the first clamping portion 611 contacts the outer side wall of the lower side plate 2022, and the outer side of the first clamping portion 611 protrudes from the outer side wall of the lower side plate 2022. When the unlocking component 600 is pulled, the first cantilever 610 drives the first clamping portion 611 to move, which can change the connection relationship between the first clamping portion 611 and the cage 106, and thus can change the connection relationship between the optical module and the host computer, and release the fixation of the optical module 200 and the host computer.

[0129] As shown, Figures 5A-5C As shown, in some embodiments, the unlocking component 600 can include a second cantilever 620, which can be located on the outer side of the lower side plate 2022. An end of the second cantilever 620 is formed with a second clamping portion 621, which clamps the cage 106, and thus can fix the optical module 200 in the cage 106. Exemplarily, the inner side of the second clamping portion 621 contacts the outer side wall of the lower side plate 2022, and the outer side of the second clamping portion 621 protrudes from the outer side wall of the lower side plate 2022.

[0130] As shown, Figures 5A-5B As shown, in some embodiments, the unlocking component 600 can include a bridge portion 630. The bridge portion 630 is located on the outer side of the housing, one side of the bridge portion 630 is connected to the first cantilever 610, and the other side of the bridge portion 630 is connected to the second cantilever 620. Exemplarily, the bridge portion 630 is located on the outer side of the bottom plate 2021 close to the optical port, one side of the bridge portion 630 is connected to the side edge of the first cantilever 610, and the other side of the bridge portion 630 is connected to the side edge of the second cantilever 620.

[0131] As shown, Figures 5A-5B As shown, in some embodiments, the unlocking component 600 can include a holding portion 640, which is connected to the first cantilever 610 and the second cantilever 620. The holding portion 640 is used to facilitate the pulling of the first cantilever 610 and the second cantilever 620. Exemplarily, one side of the end of the holding portion 640 is connected to the first cantilever 610, and the other side of the end of the holding portion 640 is connected to the second cantilever 620. Of course, in some embodiments, the holding portion 640 can be connected to the bridge portion 630.

[0132] As shown, Figures 5A-5BAs shown, in some embodiments, the unlocking component 600 may include an elastic member 650 disposed on the housing. The elastic member 650 is used to elastically reset the first cantilever 610, the second cantilever 620, and the bridge portion 630. For example, a receiving groove 2023 is disposed on the outer side of the base plate 2021. One side of the receiving groove 2023 is adjacent to an edge of one side of the base plate 2021, and the other side of the receiving groove 2023 is adjacent to an edge of the other side of the base plate 2021. The elastic member 650 is disposed within the receiving groove 2023. The bridge portion 630 may contact and connect with the elastic member 650. The elastic member 650 may be a structural member with elastic recovery capabilities, such as a spring.

[0133] In some embodiments, a reset member is formed on the bridge portion 630 and assembled with an elastic member 650. When force is applied to pull the grip portion 640, the reset member contacts the elastic member 650. As the bridge portion 630 moves, the reset member compresses the elastic member 650, causing elastic deformation of the elastic member 650. When the force is reduced or removed, the elastic member 650 returns to its original position, pushing the bridge portion 630 in the opposite direction, thereby restoring the first and second cantilever arms 610 and 620.

[0134] In some embodiments, the bridging portion 630 includes a bridging body 631, one end of which is connected to the first cantilever 610 and the other end of which is connected to the second cantilever 620. The bridging body 631 is located outside one end of the bottom plate 2021 and covers the receiving groove 2023 to reduce the risk of the elastic member 650 being separated from the receiving groove 2023.

[0135] In some embodiments, the bridge portion 630 includes a reset body 632, the top of which is connected to the side of the bridge body 631 and the bottom of which is located below the bridge body 631. Exemplarily, the reset body 632 is located on a side of the bridge body 631 away from the optical port.

[0136] Figures 5A-5B The structure of an elastic member according to some embodiments is Figure 5C , Figure 6A The structure of an elastic member according to some embodiments is Figure 1 .like Figure 6B As shown, in some embodiments, the elastic member 650 includes a receiving portion 651 that extends along the width of the optical module 200. The receiving portion 651 is located below the bridging body 631 and on the side of the reset body 632. The receiving portion 651 can contact and connect with the reset body 632. In other words, the receiving portion 651 can withstand the force applied by the reset body 632 and apply force to the reset body 632. For example, one end of the receiving portion 651 is adjacent to one side edge of the base plate 2021, and the other end of the receiving portion 651 is adjacent to the other side edge of the base plate 2021.

[0137] In some embodiments, the elastic member 650 includes a first elastic portion 652 and a second elastic portion 653, both of which are located on one side of the receiving portion 651. The other end of the first elastic portion 652 is closer to the receiving portion 651 than one end of the first elastic portion 652, and the other end of the second elastic portion 653 is closer to the receiving portion 651 than one end of the second elastic portion 653. Exemplarily, the first elastic portion 652 extends from a position away from the receiving portion 651 to a position closer to the receiving portion 651, such that one end of the first elastic portion 652 is farther away from the receiving portion 651 than the other end of the first elastic portion 652. The second elastic portion 653 extends from a position away from the receiving portion 651 to a position closer to the receiving portion 651, such that one end of the second elastic portion 653 is farther away from the receiving portion 651 than the other end of the second elastic portion 653.

[0138] The distance between one end of the first elastic portion 652 and one end of the second elastic portion 653 is greater than the distance between the other end of the first elastic portion 652 and the other end of the second elastic portion 653. The distance between one end of the first elastic portion 652 and one end of the second elastic portion 653 is L1, and the distance between the other end of the first elastic portion 652 and the other end of the second elastic portion 653 is L2. From one end of the first elastic portion 652 to the other end of the first elastic portion 652, the distance between the first elastic portion 652 and the second elastic portion 653 gradually decreases, where L1>L2. When the reset body 632 applies force to the receiving portion 651, the receiving portion 651 is subjected to the force, causing the first elastic portion 652 and the second elastic portion 653 to deform, and L2 decreases. During the process of the first elastic portion 652 and the second elastic portion 653 recovering from their deformation, L2 increases.

[0139] In some embodiments, the first elastic portion 652 and the second elastic portion 653 can be symmetrically arranged on one side of the receiving portion 651. The side wall of the receiving groove 2023 can connect one end of the first elastic portion 652 and one end of the first elastic portion 652 to provide support when the elastic member 650 is subjected to the pressure of the reset body 632 and when the elastic member 650 is recovering.

[0140] In some embodiments, the elastic member 650 includes a first connecting portion 654, one end of which is connected to the other end of the first elastic portion 652, and the other end of the first connecting portion 654 is connected to one end of the receiving portion 651. The first connecting portion 654 is used to connect the first elastic portion 652 to the receiving portion 651, thereby transmitting the force applied to the receiving portion 651 to the first elastic portion 652, thereby generating elastic deformation on the first elastic portion 652.

[0141] In some embodiments, the elastic member 650 includes a second connecting portion 655, one end of the second connecting portion 655 being connected to the other end of the second elastic portion 653, and the other end of the second connecting portion 655 being connected to the other end of the receiving portion 651. The second connecting portion 655 is configured to connect the second elastic portion 653 to the receiving portion 651, so as to transmit the force of the receiving portion 651 to the second elastic portion 653, and further generate elastic deformation on the second elastic portion 653.

[0142] In some embodiments, the first connecting portion 654 and the second connecting portion 655 can be symmetrically arranged on one side of the receiving portion 651.

[0143] In some embodiments, the first connecting portion 654 can include a first connecting segment 6542, the first connecting segment 6542 being configured to connect the first elastic portion 652 and the receiving portion 651, so as to realize the transition connection of one end of the receiving portion 651 to the other end of the first elastic portion 652. For example, the first connecting segment 6542 is arranged obliquely, so that the distances from the two ends of the first connecting segment 6542 to the receiving portion 651 are different.

[0144] In some embodiments, the first connecting segment 6542 can extend from a position away from the receiving portion 651 to a position close to the receiving portion 651, so that one end of the first connecting segment 6542 is away from the receiving portion 651, and the other end of the first connecting segment 6542 is close to the receiving portion 651. For example, the first connecting segment 6542 can be parallel to the first elastic portion 652, so that the first connecting segment 6542 can also generate elastic deformation when transmitting the force.

[0145] In some embodiments, the first connecting portion 654 can include a first extension segment 6541, the first extension segment 6541 being connected to the first elastic portion 652. The first extension segment 6541 is configured to extend the first connecting segment 6542 to the first elastic portion 652, so as to facilitate the connection of the first connecting segment 6542 to the first elastic portion 652. For example, one end of the first extension segment 6541 is connected to the other end of the first elastic portion 652, and the other end of the first extension segment 6541 is connected to the first connecting segment 6542. The first extension segment 6541 can extend along a direction perpendicular to the extension direction of the receiving portion 651.

[0146] In some embodiments, the first connecting portion 654 can include a second extension segment 6543, the second extension segment 6543 being connected to the receiving portion 651. The second extension segment 6543 is configured to extend the first connecting segment 6542 to the receiving portion 651, so as to facilitate the connection of the first connecting segment 6542 to the receiving portion 651. For example, one end of the second extension segment 6543 is connected to one end of the first connecting segment 6542, and the other end of the second extension segment 6543 is connected to one end of the receiving portion 651. The second extension segment 6543 can extend along a direction perpendicular to the extension direction of the receiving portion 651.

[0147] In some embodiments, the second connecting portion 655 may include a second connecting segment 6552, which is used to connect the second elastic portion 653 and the receiving portion 651 to achieve a transition connection from the other end of the receiving portion 651 to the other end of the second elastic portion 653. For example, the second connecting segment 6552 is arranged at an angle so that the distances from the two ends of the second connecting segment 6552 to the receiving portion 651 are different.

[0148] In some embodiments, the second connecting segment 6552 may extend from a position away from the receiving portion 651 to a position closer to the receiving portion 651, such that one end of the second connecting segment 6552 is away from the receiving portion 651 and the other end of the second connecting segment 6552 is closer to the receiving portion 651. For example, the second connecting segment 6552 may be parallel to the second elastic portion 653, so that the second connecting segment 6552 can also generate elastic deformation when transmitting force.

[0149] In some embodiments, the second connecting portion 655 may include a third extension segment 6551, which is connected to the second elastic portion 653. The third extension segment 6551 is used to extend the second connecting segment 6552 to the second elastic portion 653, thereby facilitating the connection between the second connecting segment 6552 and the second elastic portion 653. For example, one end of the third extension segment 6551 is connected to the second elastic portion 653, and the other end of the third extension segment 6551 is connected to the second connecting segment 6552. The third extension segment 6551 may extend in a direction perpendicular to the extension direction of the receiving portion 651.

[0150] In some embodiments, the second connecting portion 655 may include a fourth extension segment 6553, which is connected to the receiving portion 651. The fourth extension segment 6553 is used to extend the second connecting segment 6552 to the receiving portion 651, thereby facilitating the connection of the second connecting segment 6552 to the receiving portion 651. For example, one end of the fourth extension segment 6553 is connected to one end of the second connecting segment 6552, and the other end of the fourth extension segment 6553 is connected to the other end of the receiving portion 651. The fourth extension segment 6553 may extend in a direction perpendicular to the extension direction of the receiving portion 651.

[0151] In some embodiments, the elastic member 650 may include a first fixing portion 656, which is located at one end of the first elastic portion 652. The first fixing portion 656 may be connected to the receiving groove 2023. The first fixing portion 656 is used to connect the elastic member 650 to the receiving groove 2023, so as to fix one end of the first elastic portion 652 in the receiving groove 2023. For example, the top of the first fixing portion 656 is connected to the first elastic portion 652, and the bottom of the first fixing portion 656 is connected to the receiving groove 2023.

[0152] In some embodiments, the elastic member 650 may include a second fixing portion 657, which is located at one end of the second elastic portion 653. The second fixing portion 657 may be connected to the receiving groove 2023. The second fixing portion 657 is used to connect the elastic member 650 to the receiving groove 2023, so as to fix one end of the second elastic portion 653 in the receiving groove 2023. For example, the top of the second fixing portion 657 is connected to the second elastic portion 653, and the bottom of the second fixing portion 657 is connected to the receiving groove 2023.

[0153] Figure 2 The structure of an elastic member according to some embodiments is Figures 6A-6B , Figure 6C FIG shows a pulling grip portion, a force on an elastic member, and a direction of deformation ratio; wherein the solid arrow is the force direction, and the dotted arrow is the deformation direction. In some embodiments, as Figure 3 In the direction shown, when the grip portion 640 is pulled, the receiving portion 651 is subjected to leftward pressure, causing the receiving portion 651 to move leftward, away from its initial position. On the elastic member 650, this pressure is decomposed into a first pressure 01 and a second pressure 02. The first pressure 01 is transmitted to the first elastic portion 652 via the first connecting portion 654. The first pressure 01 causes the first elastic portion 652 to deform, and the other end of the first elastic portion 652 moves leftward, allowing the receiving portion 651 to move leftward. The second pressure 02 is transmitted to the second elastic portion 653 via the second connecting portion 655. The second pressure 02 causes the second elastic portion 653 to deform, and the other end of the second elastic portion 653 moves leftward, allowing the receiving portion 651 to move leftward. When the holding portion 640 is released, the first elastic portion 652 and the second elastic portion 653 are deformed and restored, the other end of the first elastic portion 652 moves to the right, and the other end of the second elastic portion 653 moves to the right, so that the receiving portion 651 moves to the right to push the reset body 632, thereby causing the bridging portion 630, the first cantilever 610, etc. to return to their corresponding initial positions.

[0154] In some embodiments, when the first pressure O1 is transmitted from the first connecting portion 654 to the first elastic portion 652, the other end of the first connecting segment 6542 also moves leftward, causing the first connecting segment 6542 to deform, which can move the receiving portion 651 leftward. When the grip 640 is released, the first connecting segment 6542 recovers its deformation, and the other end of the first connecting segment 6542 moves rightward, causing the receiving portion 651 to move rightward.

[0155] In some embodiments, during the process that the second pressure 02 transmits the second elastic part 653 from the second connecting part 655, the other end of the second connecting segment 6552 will also move to the left, making the second connecting segment 6552 deformed, and enabling the receiving part 651 to move to the left. When the holding part 640 is released, the second connecting part 655 returns to its original shape, and the other end of the second connecting segment 6552 moves to the right, making the receiving part 651 move to the right.

[0156] Figure 6C A structure diagram of an unlocking part according to some embodiments.
