[0050] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the multi-channel antenna shifting device and antenna equipment provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0051] The present disclosure will be described more fully hereinafter with reference to the accompanying drawings, but the illustrated embodiments may be embodied in different forms, and the present disclosure should not be construed as limited to the embodiments set forth below. Rather, these embodiments are provided so that the present disclosure will be thorough and complete and will fully understand the scope of the present disclosure to those skilled in the art.
[0052] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure and constitute a part of the specification. Together with the detailed embodiments, they are used to explain the present disclosure and do not constitute a limitation of the present disclosure. The above and other features and advantages will become more apparent to those skilled in the art by describing the detailed embodiments with reference to the accompanying drawings.
[0053] The present disclosure may be described with reference to plan views and / or cross-sectional views by way of ideal schematic views of the present disclosure. Therefore, the exemplary illustrations may be modified according to manufacturing techniques and / or tolerances.
[0054] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.
[0055] The terms used in this disclosure are only used to describe specific embodiments and are not intended to limit the disclosure. As used in this disclosure, the term "and / or" includes any and all combinations of one or more related enumerated items. As used in this disclosure, the singular forms "a" and "the" are also intended to include plural forms, unless the context clearly indicates otherwise. As used in this disclosure, the terms "comprising" and "made of" specify the presence of the features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof.
[0056] Unless otherwise defined, all terms (including technical and scientific terms) used in this disclosure have the same meanings as those commonly understood by those skilled in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless expressly defined in this disclosure.
[0057] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.
[0058] With the continuous increase in mobile communication standards and frequency bands, the number of supporting antenna units required to process wireless resources is also increasing. Therefore, in the case of site sharing, many antenna units must be installed in a base station, resulting in a heavy load-bearing burden on the base station tower, insufficient space for the layout of antenna units, a large total volume, and serious visual pollution.
[0059] Some related technologies utilize antenna units with multiple operating positions. Specifically, the antenna units are equipped with adjustment devices. Changing the position of these adjustment devices can alter the antenna unit's structure, thereby changing parameters such as the phase angle and bandwidth, placing it in different operating positions. This allows an antenna unit to switch to the appropriate operating position based on specific needs at any given time, processing wireless resources of the corresponding standard and frequency band, thereby reducing the number of antenna units required.
[0060] To improve integration, multiple antenna units can be set in one antenna device, and the adjustment devices of these antenna units can be driven by a multiple antenna shift device, that is, the working gears of the multiple antenna units can be controlled by the multiple antenna shift device.
[0061] To this end, an embodiment of the present disclosure provides a new multi-channel antenna shifting device.
[0062] First, refer to Figures 1 to 11, an embodiment of the present disclosure provides a multi-channel antenna shifting device.
[0063] Reference Figure 1 In the disclosed embodiment, the antenna device includes multiple antenna units 8. Each antenna unit 8 is an antenna structure capable of relatively independent processing of wireless resources, and includes an adjustment device 81. By changing the position of adjustment device 81, the actual structure of antenna unit 8 can be changed accordingly, thereby changing parameters such as the phase angle and beamwidth of antenna unit 8, thereby switching the antenna unit 8 between different operating modes.
[0064] In some embodiments, the adjustment device 81 includes at least one of the following: a phase shifter slider; and an isolation strip.
[0065] As one embodiment of the present disclosure, the adjustment device 81 may include a phase shifter slide, that is, a sliding adjustment structure in the phase shifter of the antenna unit 8. By changing the position of the phase shifter slide, the phase angle of the antenna unit 8 can be adjusted.
[0066] Alternatively, as another embodiment of the present disclosure, the adjustment device 81 of the antenna unit 8 may also include an isolation strip, which may be arranged on the array surface of the antenna unit 8, so that the beam width of the antenna unit 8 can be adjusted by changing the position of the isolation strip.
[0067] It should be understood that the adjustment device 81 in the embodiment of the present disclosure is not limited to the above-mentioned forms of phase shifter slides and isolation strips, and the parameters that can be adjusted in the antenna unit 8 are not limited to the above-mentioned phase angle and beam width.
[0068] Reference Figure 1 The multi-channel antenna shifting device of the embodiment of the present disclosure is arranged in the above antenna equipment and is respectively connected to the adjustment device 81 of each antenna unit 8, so it can independently drive the adjustment device 81 of each antenna unit 8 to move to the desired position, that is, independently switch the working gear of each antenna unit 8 to realize "multi-channel antenna shifting".
[0069] It should be understood that the antenna device of the embodiment of the present disclosure includes, in addition to the above antenna unit 8 and the multi-channel antenna shifting device, other structures, such as a radio frequency circuit for processing signals, an input device for controlling the multi-channel antenna shifting device, etc., which will not be described in detail here.
[0070] Reference Figures 2 to 4 The multi-path antenna shifting device of the embodiment of the present disclosure includes:
[0071] A plurality of movable racks 1 extending along a first direction 91, the movable racks 1 being used to connect to the adjustment device 81 of the antenna unit 8; the plurality of movable racks 1 are arranged side by side along a second direction 92 intersecting the first direction 91, and the teeth of all movable racks 1 are oriented in the same direction;
[0072] A shift rack 2 is provided on a side of each movable rack 1 having teeth, the shift rack 2 extending along the second direction 92, the teeth of the shift rack 2 being provided on a side facing away from the movable rack 1, and engaging teeth 291 matching the teeth of the movable rack 1 are provided on a side of the shift rack 2 facing the movable rack 1;
[0073] a first driving unit for driving the shift rack 2 to move in the second direction 92 so that the engaging teeth 291 engage with the teeth of the movable rack 1 to be adjusted;
[0074] The second driving unit is used to drive the shift rack 2 to move along the first direction 91 , so as to drive the movable rack 1 to be adjusted to move along the first direction 91 .
[0075] Reference Figures 2 to 4 The multi-path antenna shifting device of the embodiment of the present disclosure includes a plurality of movable racks 1, each movable rack 1 is directly or indirectly connected to the adjustment device 81 of the antenna unit 8, for example, Figure 3 The lower end of the movable rack 1 is connected to the adjusting device 81 through the connecting member 71; thus, when the movable rack 1 moves, it can drive the corresponding adjusting device 81 to move, thereby realizing the working gear switching of the antenna unit 8.
[0076] Each moving rack 1 may extend along a first direction 91, and a plurality of moving racks 1 may be arranged side by side along a second direction 92, with the teeth of each moving rack 1 facing the same direction. Figure 2 Perpendicular to each other.
[0077] The multi-channel antenna shifting device also includes a shift rack 2 extending along the second direction 92. The shift rack 2 is arranged on the side where the teeth of each movable rack 1 are located. Its own teeth are located on the side away from the movable rack 1, and an engaging tooth 291 is provided on the side facing the movable rack 1. The engaging tooth 291 can engage with the teeth of the movable rack 1.
[0078] The first drive unit can drive the shift rack 2 to move in the second direction 92, thereby causing its engaging teeth 291 to engage with the teeth of different mobile racks 1. The mobile rack 1 currently engaged with the engaging teeth 291 is the "mobile rack 1 to be adjusted." Therefore, the first drive unit is equivalent to controlling the shift rack 2 to select the mobile rack 1 to be adjusted, that is, to select the antenna unit 8 to be adjusted. The second drive unit can drive the shift rack 2 to move in the first direction 91, and drive the mobile rack 1 to be adjusted currently engaged with the engaging teeth 291 to move synchronously, thereby driving the adjustment device 81 of the antenna unit 8 to be adjusted to adjust the working gear of the antenna unit 8 to be adjusted.
[0079] The multi-channel antenna shifting device of the embodiment of the present disclosure can drive the shift rack 2 to move and select the movable rack 1 to be adjusted, that is, select the antenna unit 8 to be adjusted, through the first driving unit; and then drive the shift rack 2 and the movable rack 1 to be adjusted to move together through the second driving unit, that is, drive the adjustment device 81 of the antenna unit 8 to be adjusted to move, so as to achieve the adjustment of the working gear of the antenna unit 8; wherein, since the shift rack 2 and the movable rack 1 move together in the embodiment of the present disclosure, compared with the method in the related art that the shift structure is stationary and the movable structure moves, the multi-channel antenna shifting device of the embodiment of the present disclosure has a small number of components, a simple structure, a small size, and a low cost.
[0080] Reference Figure 5 、 Figure 6 In some embodiments, the shift rack 2 has two engaging teeth 291 , which are respectively located at the two ends of the shift rack 2 along the second direction 92 ; the distance between the two engaging teeth 291 is greater than the distance between the two most distant moving racks 1 in the second direction 92 .
[0081] As one embodiment of the present disclosure, refer to Figure 5 、 Figure 6 , the shift rack 2 can be provided with a locking tooth 291 at each end, and the distance between the locking teeth 291 at each end is greater than the distance between the two most distant moving racks 1. This ensures that no matter what position the shift rack 2 moves to, both locking teeth 291 will not engage with the moving rack 1 at the same time, and that the shift rack 2 can "uniquely" select the moving rack 1 to be adjusted. As a result, the two locking teeth 291 of the shift rack 2 can each be responsible for engaging with a portion of the moving rack 1, for example, each responsible for approximately "half" of the moving rack 1. As a result, compared to a configuration with only one locking tooth 291, the shift rack 2 only needs to move within a smaller range in the second direction 92 to ensure that any moving rack 1 can engage with the locking tooth 291, thereby reducing the requirements for the first drive unit.
[0082] Reference Figure 4 、 Figure 5 In some embodiments, the shift rack 2 is disposed in the shift guide frame 21 , and a first opening 2191 is provided on a side of the shift guide frame 21 facing the movable rack 1 , and the engaging tooth 291 extends out of the shift guide frame 21 through the first opening 2191 ;
[0083] The first driving unit is used to drive the shift rack 2 to move in the shift guide frame 21 along the second direction 92;
[0084] The second driving unit is used to drive the shift guide frame 21 to move along the first direction 91 .
[0085] As one embodiment of the present disclosure, refer to Figure 5The shift rack 2 can be set in a shift guide frame 21 that serves as a guide. The shift guide frame 21 has a first opening 2191 on the side facing the movable rack 1, so that the engaging tooth 291 of the shift rack 2 can extend from the first opening 2191 and engage with the movable rack 1.
[0086] Reference Figure 4 The shift guide frame 21 is fixed in the second direction 92. Therefore, the shift rack 2 can move relative to the shift guide frame 21 under the drive of the first drive unit, that is, move in the second direction 92. The second drive unit can drive the "entire" shift guide frame 21 to move in the first direction 91, that is, drive the shift rack 2 therein to move in the first direction 91.
[0087] In the above manner, the independent movement of the shift guide frame 21 in the first direction 91 and the second direction 92 can be achieved with a simple structure.
[0088] Reference Figure 3 、 Figure 4 In some embodiments, the first driving unit includes a first motor 31 , the output shaft of the first motor 31 is connected to a shift gear 311 , and the teeth of the shift gear 311 are engaged with the teeth of the shift rack 2 ;
[0089] The second drive unit includes a second motor 32 , the output shaft of the second motor 32 is connected to a shift screw 321 extending along the first direction 91 , the shift screw 321 passes through the shift guide frame 21 , and the shift guide frame 21 is provided with an internal thread engaged with the external thread of the shift screw 321 .
[0090] As one embodiment of the present disclosure, refer to Figure 3 、 Figure 4 The first drive unit may include a first motor 31, with a shift gear 311, such as a spur gear, mounted on the output shaft of the first motor 31. The teeth of the shift gear 311 mesh with the teeth of the shift rack 2. For example, the first motor 31 may be mounted on the shift guide frame 21 so that it moves along with the shift guide frame 21. The shift gear 311 connected to the first motor 31 is mounted within the shift guide frame 21 and meshes with the shift rack 2. Thus, when the first motor 31 is operating, the shift gear 311 rotates, driving the shift rack 2 to move within the shift guide frame 21 in the second direction 92.
[0091] Reference Figure 3 、 Figure 4The second drive unit may be a second motor 32. The output shaft of the second motor 32 is connected to a shift screw 321 extending in the first direction 91. For example, the output shaft may be enclosed by the shift screw 321. The shift screw 321 extends through the shift guide frame 21, and its external threads mate with the internal threads of the shift guide frame 21. For example, the second motor 32 may be fixed relative to the base 79, which is used to support other structures. Thus, the second motor 32 is also fixed relative to the other structures. The shift screw 321 connected to the second motor 32 may pass through the middle of the shift guide frame 21. The shift guide frame 21 may also be passed through by multiple guide rods 72 provided on the base 79 to prevent the shift guide frame 21 from rotating. Thus, when the second motor 32 is operating, the shift screw 321 rotates, driving the shift guide frame 21 and the shift rack 2 therein to move in the first direction 91.
[0092] In the above manner, the movement of the shift rack 2 in two directions is independently driven by two motors, that is, complete decoupling of the movement in the two directions is achieved. It does not require the coupling of different drive units in the related technology, so the control difficulty is greatly reduced, the product structure is simplified, the size is reduced, and the reliability is improved.
[0093] In addition, the above method realizes the drive along the second direction 92 and the first direction 91 respectively through the direct cooperation between the shift gear 311 and the shift rack 2, and the direct cooperation between the shift screw 321 and the shift guide frame 21. Compared with the driving method using a gear pair in the related art, it has a simple structure, a small size, a low cost and good reliability.
[0094] Reference Figure 1 、 Figure 2 、 Figure 7 In some embodiments, each movable rack 1 has a corresponding locking unit 4, and the locking unit 4 is used to fix the position of the movable rack 1 when its corresponding movable rack 1 is not the movable rack 1 to be adjusted.
[0095] According to the embodiment of the present disclosure, the teeth of the current movable rack 1 to be adjusted are engaged with the engaging teeth 291 of the shift rack 2, so that it can be driven by the shift rack 2 to move along the first direction 91 to achieve the adjustment of the working gear of the antenna unit 8 to be adjusted; while the working gears of other "non-to-be-adjusted" antenna units 8 should be fixed.
[0096] To this end, as one embodiment of the present disclosure, refer to Figure 1 、 Figure 2 、 Figure 7 A corresponding locking unit 4 can also be set for each moving rack 1. The locking unit 4 is used to relatively fix the position of the corresponding moving rack 1 when it is not the moving rack 1 to be adjusted, so as to ensure that the position of the corresponding adjustment device 81 is fixed and the working gear of the antenna unit 8 remains unchanged.
[0097] It should be understood that when the moving rack 1 is selected as the moving rack 1 to be adjusted, its corresponding locking unit 4 can also “unlock” the moving rack 1 to allow the moving rack 1 to move better.
[0098] Reference Figures 7 to 10 , in some embodiments, along the second direction 92 , the locking unit 4 is located on one side of the corresponding moving rack 1 ;
[0099] Each movable rack 1 is disposed in a movable guide frame 11. A second opening 1192 is provided on a side of the movable guide frame 11 facing the shift rack 2. A first side wall 111 is provided on a side of the movable rack 1 facing away from the corresponding locking unit 4.
[0100] The locking unit 4 is used to apply pressure to the moving rack 1 when the corresponding moving rack 1 is not the moving rack 1 to be adjusted, so as to press the moving rack 1 onto the first side wall 111 of the moving guide frame 11 where it is located.
[0101] As one embodiment of the present disclosure, refer to Figures 7 to 10 The movable rack 1 can be arranged in a movable guide frame 11 which plays a guiding role, referring to Figure 10 The movable guide frame 11 has a second opening 1192 on the side facing the shift rack 2, for the engagement teeth 291 of the shift rack 2 to be inserted and meshed with the teeth of the movable rack 1. In this case, refer to Figure 7 、 Figure 10 Along the second direction 92, the locking unit 4 can be arranged on one side of the corresponding moving rack 1, and the locking unit 4 can "press" the moving rack 1 to the other side when the corresponding moving rack 1 is not the moving rack 1 to be adjusted, thereby pressing the moving rack 1 on the first side wall 111 of the moving guide frame 11 to fix the position of the moving rack 1.
[0102] Reference Figures 8 to 10 In some embodiments, the locking unit 4 includes:
[0103] The locking frame 41 has a third opening 4193 on the side facing the shift rack 2, a bottom wall 419 on the side opposite to the third opening 4193, and a second side wall 412 on the side facing away from the corresponding moving rack 1;
[0104] A first slider 421 is disposed in the locking frame 41 and contacts the second side wall 412 ;
[0105] A first elastic member 431 is disposed between the first slider 421 and the bottom wall 419 and is used to apply a force to the first slider 421 away from the bottom wall 419;
[0106] The second slider 422 is disposed within the locking frame 41 and contacts the side of the first slider 421 facing away from the second side wall 412. The side of the second slider 422 facing away from the first slider 421 is used to apply pressure to the corresponding movable rack 1. The contact surfaces of the second slider 422 and the first slider 421 form a sliding pair. The sliding pair is configured to allow the second slider 422 to move toward the second side wall 412 when the first slider 421 moves toward the bottom wall 419.
[0107] Among them, reference Figure 6 、 Figure 11 The shift rack 2 is further provided with an unlocking pressure head 292 corresponding to the engaging tooth 291 on the side facing the movable rack 1. The structure of the unlocking pressure head 292 is configured as follows: when the corresponding engaging tooth 291 is engaged with the teeth of any movable rack 1, a force directed toward the bottom wall 419 is applied to the first slider 421 of the locking unit 4 corresponding to the movable rack 1.
[0108] As one embodiment of the present disclosure, refer to Figure 8 、 Figure 10 The locking unit 4 may include a locking frame 41, which has a third opening 4193 on the side facing the shift rack 2, and a bottom wall 419 on the opposite side of the third opening 4193; the locking frame 41 is provided with a second side wall 412 on the side facing away from the corresponding moving rack 1, and the second side wall 412 can be connected to the bottom wall 419, so that the cross section of the locking frame 41 can form a structure similar to an "L-shape".
[0109] Reference Figure 8 、 Figure 10 A first slider 421 and a second slider 422 are further provided in the locking frame 41 .
[0110] Among them, reference Figure 10 One side of the first slider 421 contacts the second side wall 412 and is connected to the bottom wall 419 via one or more first elastic members 431. The first elastic members 431 can apply a force to the first slider 421 away from the bottom wall 419, that is, a force that pushes the first slider 421 away from the bottom wall 419. The second slider 422 is located between the corresponding movable rack 1 and the first slider 421. The side of the second slider 422 facing the movable rack 1 can apply pressure to the movable rack 1, thereby pressing the movable rack 1 against the first side wall 111 of the movable guide frame 11. At the same time, the side of the second slider 422 facing the first slider 421 also contacts the first slider 421, forming a "sliding pair." Through the action of this sliding pair, when the first slider 421 moves toward the bottom wall 419, the second slider 422 moves toward the second side wall 412. Correspondingly, when the first slider 421 moves away from the bottom wall 419, the second slider 422 also moves away from the second side wall 412.
[0111] Further, refer to Figure 6, the side where the engaging teeth 291 of the shift rack 2 are located is further provided with an unlocking pressure head 292 corresponding to each engaging tooth 291; and referring to Figure 11 The relative positions of the corresponding unlocking press heads 292 and the engaging teeth 291 can ensure that when the engaging teeth 291 engage with the teeth of a certain movable rack 1, the corresponding unlocking press head 292 can pass through the third opening 4193 of the locking frame 41 corresponding to the movable rack 1 and press the side of the first slider 421 away from the bottom wall 419.
[0112] Reference Figures 8 to 10 In some embodiments, the locking unit 4 further comprises:
[0113] The second elastic member 432 is used to apply a force to the second slider 422 toward the first slider 421 .
[0114] As one embodiment of the present disclosure, refer to Figure 10 A second elastic member 432 may also be provided to apply a force to the second slider 422 toward the first slider 421 , that is, to press the second slider 422 toward the first slider 421 , thereby better ensuring that the second slider 422 can release the movable rack 1 in the unlocked state.
[0115] Therefore, the locking unit 4 of the embodiment of the present disclosure can work in the following manner:
[0116] (1) Reference Figure 10 When a certain moving rack 1 is not the moving rack 1 to be adjusted, the shift rack 2 is not in its corresponding position, and the first slider 421 of the corresponding locking unit 4 does not contact the unlocking pressure head 292. Therefore, the first elastic member 431 can push the first slider 421 away from the bottom wall 419 of the locking frame 41, and the first slider 421 pushes the second slider 422 toward the moving rack 1. The second slider 422 presses the moving rack 1 against the first side wall 111 of the shift guide frame 21 with a greater force. The moving rack 1 is positioned and cannot move in the shift guide frame 21, thereby achieving "locking".
[0117] (2) Reference Figure 11 When a certain moving rack 1 is the moving rack 1 to be adjusted, its teeth engage with the engaging teeth 291 of the shift rack 2, and the unlocking pressure head 292 corresponding to the engaging teeth 291 presses on the first slider 421 corresponding to the moving rack 1, compressing the first elastic member 431, so that the first slider 421 moves toward the bottom wall 419 of the locking frame 41; then, the second slider 422 has space to move toward the second side wall 412 of the locking frame 41, and under the action of the second elastic member 432, it moves away from the moving rack 1 and presses the moving rack 1 to release it from the first side wall 111 of the shift guide frame 21. The moving rack 1 to be adjusted is "unlocked" and can move in the shift guide frame 21.
[0118] According to the above-mentioned locking unit 4, the movable rack 1 can be locked or unlocked by the "damping" effect of the elastic member. Compared with the passive locking structure using silicone pads in the related art, it has high reliability, high efficiency and good stability.
[0119] Reference Figure 11 In some embodiments, an unlocking protrusion 4211 is provided on the side of the first sliding block 421 facing away from the bottom wall 419 ;
[0120] The unlocking protrusion 4211 is configured as follows: when the engaging tooth 291 corresponding to the unlocking press head 292 engages with the teeth of any movable rack 1 , the unlocking press head 292 applies a force directed toward the bottom wall 419 to the first slider 421 through the unlocking protrusion 4211 .
[0121] As one embodiment of the present disclosure, refer to Figure 11 The first slider 421 may also be provided with an unlocking protrusion 4211 on the side facing away from the bottom wall 419. The unlocking ram 292 of the shift rack 2 can apply force to the first slider 421 by contacting the unlocking protrusion 4211. Thus, because the unlocking protrusion 4211 is positioned more prominently than the "other" positions of the first slider 421, the unlocking ram 292 is less likely to contact the "other" positions, thereby preventing accidental "unlocking."
[0122] It should be understood that the specific forms of the locking unit 4 in the embodiment of the present disclosure are various.
[0123] For example, refer to Figure 10 、 Figure 11 The first elastic member 431 may be in the form of a spring, which is arranged between the first slider 421 and the bottom wall 419 in a compressed state, thereby pushing the first slider 421 away from the bottom wall 419. Alternatively, the first elastic member 431 may also be in other forms such as a spring.
[0124] For example, refer to Figure 10 、 Figure 11 The second elastic member 432 can be a spring, such as a coil spring, which is arranged in a compressed state between the third side wall 113 of the movable guide frame 11 toward the locking unit 4 and the second slider 422, thereby pushing the second slider 422 toward the second side wall 412. Alternatively, the second elastic member 432 can also be a spring that "pulls" the second slider 422 toward the second side wall 412.
[0125] For example, refer to Figure 10 、 Figure 11, the side of the locking frame 41 facing the movable guide frame 11 can be "open", and the side of the movable guide frame 11 facing the locking frame 41 can have the above-mentioned third side wall 113, and the third side wall 113 can have multiple holes for the push rods 4221 of each second slider 422 to pass through, so that the second slider 422 can apply pressure to the movable rack 1 through the push rod 4221; for another example, the spring of the above-mentioned second elastic member 432 can be arranged outside the push rod 4221, so as to be arranged between the second slider 422 and the third side wall 113. Alternatively, the side of the movable guide frame 11 facing the locking frame 41 can be open, and the side of the locking frame 41 facing the movable guide frame 11 can have a side wall with a hole, so that the second elastic member 432 can be arranged between the side wall with a hole and the second slider 422.
[0126] For example, refer to Figure 10 、 Figure 11 The side surfaces of the first slider 421 and the second slider 422 that contact each other can be two inclined surfaces, such as two inclined surfaces inclined at 45 degrees relative to the bottom wall 419, thereby forming the above sliding pair, or the sliding pair between the first slider 421 and the second slider 422 can also be other forms such as arc surfaces.
[0127] For example, refer to Figure 6 The unlocking press head 292 may be connected to the corresponding engaging tooth 291. Alternatively, the unlocking press head 292 and the engaging tooth 291 may also be directly connected to the shift rack 2 respectively.
