Description

Technical Field

[0001] This application relates to the field of vehicle headlight testing technology, and in particular to a testing fixture. Background Technology

[0002] Currently, vehicle lights consist of a lens module and a light source. The light emitted by the light source is refracted by the lens module and then emitted outward to meet the vehicle's nighttime lighting needs. To ensure that the brightness and illumination range of the vehicle lights meet safety standards, and to ensure that the lens module can withstand continuous vibration and impact during vehicle operation, it is necessary to conduct light distribution tests and vibration tests on the lens module.

[0003] In related technologies, when conducting light distribution tests, the lens module needs to be fixed on a light distribution fixture, and the light emitted from the lens module is captured by a detection device. Then, key optical parameters such as light intensity distribution, beam angle, and uniformity are measured to verify whether the light meets specific requirements such as clear near beam tangent and adequate far beam illumination distance. When conducting vibration tests, the lens module needs to be fixed on a vibration fixture, and vibration environments with different frequencies and amplitudes are simulated to verify whether the lens module's impact resistance meets the standards in scenarios such as vehicle driving and equipment transportation.

[0004] However, due to the differences in shape and size of different types of lens modules, it is often necessary to design a separate testing fixture for each lens module when testing them. This results in a wide variety of testing fixtures, which increases the complexity and cost of the testing process. Utility Model Content

[0005] In view of this, the present application provides a testing fixture to solve the technical problem that the testing fixture has poor versatility and cannot be adapted to various lens modules.

[0006] Firstly, this application provides a testing fixture, which includes: Base plate; The first adjusting member slides with the base plate along a first direction and can be fixed and de-fixed with the base plate. The first adjusting member extends along a second direction, which is perpendicular to the first direction. The second adjusting member slides with the first adjusting member along the second direction and can be fixed and de-fixed with the first adjusting member. The second adjusting member extends along a third direction, which is perpendicular to both the first direction and the second direction. The connector is slidably engaged with the second adjusting member along the third direction and is detachably connected to the second adjusting member. The connector is used to support and fix the lens module.

[0007] Thus, when the testing fixture needs to fix the lens module, the first adjusting member can be moved to a suitable position along the first direction and fixed to the base plate, and the second adjusting member can be moved to a suitable position along the second direction and fixed to the first adjusting member, so that a space for accommodating the lens module can be formed on the testing fixture. Then, the connecting member can be moved to a suitable position along the third direction and fixed to the second adjusting member, so that the connecting member can be adapted to support and fix a lens module of a specific shape.

[0008] When the testing fixture needs to fix lens modules of different shapes and sizes, the first adjusting member can be detached from the base plate and the second adjusting member can be detached from the first adjusting member. By moving the position of the first adjusting member, the position of the second adjusting member, and the position of the connecting member, a space can be formed on the testing fixture to accommodate the lens modules, so as to adapt to lens modules of different sizes. Furthermore, by replacing different connecting members, it is possible to facilitate the connecting members to support and fix lens modules of different shapes, so that the testing fixture can support and fix lens modules of different shapes and sizes.

[0009] As an optional implementation, the base plate is provided with a first sliding groove, the first sliding groove extends along the first direction, and the first adjusting member is provided with a first slider, the first slider slidingly engaging with the first sliding groove; The first adjusting member is provided with a second sliding groove, the second sliding groove extends along the second direction, and the second adjusting member is provided with a second slider, the second slider slidingly engaging with the second sliding groove; The second adjusting member is provided with a third sliding groove, which extends along the third direction. The connecting member is provided with a third slider, which slides in cooperation with the third sliding groove.

[0010] In this way, the staff can adjust the position of the first adjusting member along the first direction, adjust the position of the second adjusting member along the second direction, and adjust the position of the connecting member along the third direction, so that the testing fixture can be adapted to a variety of lens modules and can easily fix lens modules of different shapes and sizes.

[0011] As an optional implementation, the base plate is provided with two first sliding grooves, which are arranged in parallel, and the first adjusting member is provided with two first sliders, which are respectively slidably engaged with the two first sliding grooves.

[0012] This allows the first adjusting component to slide more stably on the base plate.

[0013] As an optional implementation, the testing fixture further includes a fastener, and the base plate is provided with a first mating groove that extends along the first direction. The first adjusting member has a first connecting hole, and the fastener is movably inserted through the first mating groove. The first end of the fastener is threadedly engaged with the first connecting hole, and the second end of the fastener is used to abut against the base plate to fix the first adjusting member to the base plate.

[0014] Thus, when the position of the first adjusting member needs to be adjusted, the fastener can be loosened so that the second end of the fastener disengages from the base plate, thereby allowing the first adjusting member to move in the first direction. The fastener can also move in the first mating groove in the first direction, making it easy to adjust the position of the first adjusting member. When the first adjusting member is moved to the appropriate position, the fastener can be tightened so that the second end of the fastener abuts against the base plate, thereby fixing the first adjusting member to the base plate and facilitating the subsequent assembly of the lens module.

[0015] As an optional implementation, the base plate has a first side and a second side disposed opposite to each other, the first side having the first sliding groove, the second side having the first mating groove, and the first mating groove communicating with the first sliding groove; The first slider has the first connecting hole, which is oriented toward the first mating groove, and the fastener is used to connect the first slider to the base plate.

[0016] Thus, the first mating groove and the first sliding groove are located on opposite sides of the base plate, and the first mating groove and the first sliding groove are connected to each other. Therefore, when grooving the base plate, the sum of the grooving depth of the first mating groove and the grooving depth of the first sliding groove is equal to the thickness of the base plate. This can reduce the grooving depth of the first mating groove, thereby reducing the difficulty of grooving the first mating groove and reducing the grooving cost.

[0017] The first slider has a first connecting hole, which allows the first end of the fastener to be threaded into the first slider. When the first adjusting member moves to the appropriate position, the fastener can directly fix the first slider to the base plate, making the first adjusting member and the base plate more stable.

[0018] As an optional implementation, the fastener includes a connecting rod and a fastening head connected to the connecting rod. The connecting rod is threaded into the first connecting hole, and the fastening head is located in the first mating groove and can rotate around the axis of the first connecting hole within the first mating groove. The fastening head is used to abut against the wall of the first mating groove so that the first adjusting member is fixed to the base plate.

[0019] Thus, when adjusting the position of the first adjusting member, since the fastening head can rotate around the axis of the first connecting hole in the first mating groove, the connecting rod can be rotated relative to the first connecting hole by directly rotating the fastening head. Under the threaded engagement between the connecting rod and the first connecting hole, the fastener moves away from the first adjusting member, causing the fastening head to disengage from the groove wall of the first mating groove, so that the first adjusting member can slide relative to the base plate in the first direction.

[0020] Once the first adjusting member has been moved to the appropriate position, the fastening head can be rotated directly. Under the threaded engagement of the connecting rod and the first connecting hole, the fastener moves towards the first adjusting member, causing the fastening head to abut against the groove wall of the first mating groove, thus fixing the first adjusting member to the base plate. This allows for easy adjustment of the position of the first adjusting member.

[0021] As an optional implementation, the first mating groove includes a first groove bottom surface and a first groove peripheral surface connected to the first groove bottom surface, and the fastening head is used to abut against the first groove bottom surface to fix the first adjusting member to the base plate.

[0022] Thus, when the fastener is tightened, the fastening head abuts against the bottom surface of the first groove, fixing the first adjusting member to the base plate, making the first adjusting member more stable.

[0023] As an optional implementation, the first mating groove includes a first groove circumferential surface, the bottom plate has a first channel, the first mating groove communicates with the first connecting hole through the first channel, the first groove circumferential surface is connected to the inner wall surface of the first channel, and the groove width of the first mating groove along the second direction is d, which gradually decreases along the groove depth direction of the first mating groove. The fastening head has an outer peripheral surface that extends around the axis of the first connecting hole and is used to abut against the peripheral surface of the first groove to fix the first adjusting member to the base plate.

[0024] Thus, when the fastener is tightened, the outer peripheral surface can abut against and fit against the peripheral surface of the first groove, which can increase the contact area between the fastener head and the peripheral surface of the first groove, so that the fastener can more stably fix the first adjusting member to the base plate and the outer peripheral surface.

[0025] As an optional implementation, the testing fixture includes a fixture table, and the number of base plates is two. The two base plates are fixed on the fixture table and arranged along the first direction. Each base plate has at least one first adjusting member, each first adjusting member has at least one second adjusting member, and each second adjusting member has at least one connecting member.

[0026] Thus, the two base plates are fixed on the tooling table, and the two base plates are arranged along the first direction, and the first sliding grooves on the two base plates are also arranged along the first direction. Each base plate is provided with a first adjusting component. By adjusting the position of the two first adjusting components, sufficient space can be provided for fixing the lens module. Each first adjusting component has a second adjusting component. By adjusting the position of the two second adjusting components, different shaped lens modules can be adapted, which facilitates the connection component to support and fix the lens module.

[0027] As an optional implementation, the two opposite ends of the connector are respectively slidably engaged with the two second adjusting members, and the middle position of the connector has a fixed position, on which the lens module is installed.

[0028] This allows the connectors to more stably support and fix the lens module. Attached Figure Description

[0033] Currently, vehicle lights consist of a lens module and a light source. The light emitted by the light source is refracted by the lens module and then emitted outward to meet the vehicle's nighttime lighting needs. To ensure that the brightness and illumination range of the vehicle lights meet safety standards, and to ensure that the lens module can withstand continuous vibration and impact during vehicle operation, it is necessary to conduct light distribution tests and vibration tests on the lens module.

[0034] In related technologies, when conducting light distribution tests, the lens module needs to be fixed on a light distribution fixture, and the light emitted from the lens module is captured by a detection device. Then, key optical parameters such as light intensity distribution, beam angle, and uniformity are measured to verify whether the light meets specific requirements such as clear near beam tangent and adequate far beam illumination distance. When conducting vibration tests, the lens module needs to be fixed on a vibration fixture, and vibration environments with different frequencies and amplitudes are simulated to verify whether the lens module's impact resistance meets the standards in scenarios such as vehicle driving and equipment transportation.

[0035] However, due to the differences in shape and size of different types of lens modules, it is often necessary to design a separate testing fixture for each lens module when testing them. This results in a wide variety of testing fixtures, which increases the complexity and cost of the testing process.

[0036] Based on this, this application provides a testing fixture 10, wherein the first adjusting member 2 can slide relative to the base plate 1 along a first direction, the second adjusting member 3 can slide relative to the first adjusting member 2 along a second direction, and the connecting member 4 can slide relative to the second adjusting member 3 along a third direction. When it is necessary to fix lens modules 20 of different shapes and sizes, the position of the first adjusting member 2, the position of the second adjusting member 3, and the position of the connecting member 4 can be moved to form a space on the testing fixture 10 to accommodate the lens modules 20, so as to adapt to lens modules 20 of different sizes. Furthermore, by replacing different connecting members 4, it is convenient for the connecting members 4 to carry and fix lens modules 20 of specific shapes, so that the testing fixture 10 can carry and fix lens modules 20 of different shapes and sizes.

[0037] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0038] Please see Figures 1 to 5 , Figure 1 This is a three-dimensional structural diagram of the detection fixture used to fix the first type of lens module according to an embodiment of this application. Figure 2 This is a three-dimensional structural diagram of the detection fixture used to fix the second lens module according to an embodiment of this application. Figure 3 This is a three-dimensional structural diagram of the detection fixture used to fix the third lens module according to an embodiment of this application. Figure 4 This is a three-dimensional structural diagram of the detection fixture used to fix the fourth type of lens module provided in the embodiments of this application. Figure 5 This is a three-dimensional structural diagram of the detection fixture used to fix the fifth type of lens module in an embodiment of this application.

[0039] As shown in the figure, this embodiment provides a testing fixture 10, which includes a base plate 1, a first adjusting member 2, a second adjusting member 3, and a connecting member 4. The first adjusting member 2 is slidably engaged with the base plate 1 along a first direction, and the first adjusting member 2 can be fixed and detached from the base plate 1. The first adjusting member 2 extends along a second direction, which is perpendicular to the first direction. The second adjusting member 3 is slidably engaged with the first adjusting member 2 along the second direction, and the second adjusting member 3 can be fixed and detached from the first adjusting member 2. The second adjusting member 3 extends along a third direction, which is perpendicular to both the first and second directions. The connecting member 4 is slidably engaged with the second adjusting member 3 along the third direction, and the connecting member 4 is detachably connected to the second adjusting member 3. The connecting member 4 is used to support and fix the lens module 20.

[0040] It should be noted that the first direction is Figure 1 In the diagram, the X-axis direction is defined as follows: the positive X-axis is to the right, the negative X-axis is to the left, and the second direction is... Figure 1 In the diagram, the Y-axis direction is defined as follows: the positive Y-axis represents the rear, the negative Y-axis represents the front, and the third direction represents the rear. Figure 1 In the Z-axis direction, the positive Z-axis is upward and the negative Z-axis is downward.

[0041] Optionally, the base plate 1 is a square plate and is fixedly mounted on the workbench. The first adjusting member 2 and the second adjusting member 3 are both square long rods. The first adjusting member 2 is horizontally mounted on the base plate 1 and slides with the base plate 1 in a first direction. The second adjusting member 3 is vertically mounted and slides with the first adjusting member 2 in a second direction. The connecting member 4 is horizontally mounted and slides with the second adjusting member 3 in a third direction.

[0042] Thus, when the testing fixture 10 needs to fix the lens module 20, the first adjusting member 2 can be moved to a suitable position along the first direction and fixed to the base plate 1, and the second adjusting member 3 can be moved to a suitable position along the second direction and fixed to the first adjusting member 2, so that a space for accommodating the lens module 20 can be formed on the testing fixture 10. Then, the connecting member 4 can be moved to a suitable position along the third direction and fixed to the second adjusting member 3, so that the connecting member 4 can be adapted to support and fix the lens module 20 of a specific shape.

[0043] When the testing fixture 10 needs to fix lens modules 20 of different shapes and sizes, the first adjusting member 2 can be de-fixed to the base plate 1, and the second adjusting member 3 can be de-fixed to the first adjusting member 2. By moving the position of the first adjusting member 2, the position of the second adjusting member 3, and the position of the connecting member 4, a space can be formed on the testing fixture 10 to accommodate the lens modules 20, so as to adapt to lens modules 20 of different sizes. Furthermore, by replacing different connecting members 4, it is convenient for the connecting members 4 to carry and fix lens modules 20 of different shapes, so that the testing fixture 10 can carry and fix lens modules 20 of different shapes and sizes.

[0044] Please see Figure 1 In some embodiments, the base plate 1 is provided with a first sliding groove 11, which extends along a first direction; the first adjusting member 2 is provided with a first slider 21, which slides in cooperation with the first sliding groove 11; the first adjusting member 2 is provided with a second sliding groove 22, which extends along a second direction; the second adjusting member 3 is provided with a second slider 31, which slides in cooperation with the second sliding groove 22; the second adjusting member 3 is provided with a third sliding groove 32, which extends along a third direction; and the connecting member 4 is provided with a third slider 41, which slides in cooperation with the third sliding groove 32.

[0045] Optionally, a first groove 11 is provided on one side of the base plate 1, extending along a first direction. A first slider 21 is provided on the side of the first adjusting member 2 facing the base plate 1, and the first slider 21 is slidably inserted into the first groove 11, so that the first adjusting member 2 can slide and cooperate with the base plate 1 along the first direction. A second groove 22 is provided on the side of the first adjusting member 2 facing away from the base plate 1, extending along a second direction. A second slider 31 is provided on the end of the second adjusting member 3 facing the base plate 1, and the second slider 31 is slidably inserted into the second groove 22, so that the second adjusting member 3 can slide and cooperate with the first adjusting member 2 along the second direction. A third groove 32 is provided on one side of the second adjusting member 3, extending along a third direction. A third slider 41 is provided on one end of the connecting member 4, and the third slider 41 is slidably inserted into the third groove 32, so that the connecting member 4 can slide and cooperate with the second adjusting member 3 along a third direction.

[0046] In this way, the staff can adjust the position of the first adjusting member 2 along the first direction, adjust the position of the second adjusting member 3 along the second direction, and adjust the position of the connecting member 4 along the third direction, so that the testing fixture 10 can be adapted to various lens modules 20, and can easily fix lens modules 20 of different shapes and sizes.

[0047] Please see Figure 1 In some embodiments, the base plate 1 is provided with two first sliding grooves 11, which are arranged in parallel, and the first adjusting member 2 is provided with two first sliders 21, which are slidably engaged with the two first sliding grooves 11 respectively.

[0048] Optionally, two first sliding grooves 11 are provided on one side of the base plate 1. The two first sliding grooves 11 are arranged at intervals along the second direction and are arranged in parallel. The first adjusting member 2 is provided with two first sliders 21 on the side facing the base plate 1. The two first sliders 21 are arranged along the second direction and one first slider 21 is slidably inserted into a corresponding first sliding groove 11. Thus, the first adjusting member 2 can slide and cooperate with the base plate 1 along the first direction, so that the first adjusting member 2 can slide more stably on the base plate 1.

[0049] Please see Figure 1 and Figure 6 In some embodiments, the testing fixture 10 further includes a fastener 5, and the base plate 1 is also provided with a first mating groove 12, which extends along a first direction. The first adjusting member 2 has a first connecting hole 23. The fastener 5 is movably inserted through the first mating groove 12, and the first end of the fastener 5 is threadedly engaged with the first connecting hole 23. The second end of the fastener 5 is used to abut against the base plate 1 so that the first adjusting member 2 is fixed to the base plate 1.

[0050] In this embodiment, the first mating groove 12 and the first sliding groove 11 are arranged parallel to each other and spaced apart. The first mating groove 12 can penetrate through the opposite sides of the base plate 1. After the fastener 5 is movably inserted through the first mating groove 12, the first end and the second end of the fastener 5 can be located on the opposite sides of the base plate 1, so that the first end of the fastener 5 can be threadedly engaged with the first connecting hole 23, and the second end of the fastener 5 can be located on the side of the base plate 1 facing away from the first adjusting member 2.

[0051] Thus, when the position of the first adjusting member 2 needs to be adjusted, the fastener 5 can be loosened so that the second end of the fastener 5 disengages from the base plate 1, thereby allowing the first adjusting member 2 to move in the first direction. The fastener 5 can also move in the first mating groove 12 in the first direction, making it easy to adjust the position of the first adjusting member 2. When the first adjusting member 2 moves to the appropriate position, the fastener 5 can be tightened so that the second end of the fastener 5 abuts against the base plate 1, thereby fixing the first adjusting member 2 to the base plate 1, which facilitates the subsequent assembly of the lens module 20.

[0052] In some embodiments, the first adjusting member 2 may be provided with a second mating groove, which is parallel to and spaced apart from the second sliding groove 22. The second mating groove can penetrate through the opposite two sides of the first adjusting member 2. The second adjusting member 3 is provided with a second connecting hole. There are multiple fasteners 5, one of which can be movably inserted into the second mating groove. The first end and the second end of the fastener 5 are respectively located on opposite sides of the first adjusting member 2. The first end of the fastener 5 is threaded into the second connecting hole, and the second end of the fastener 5 is located on the side of the first adjusting member 2 facing away from the second adjusting member 3.

[0053] Thus, when the position of the second adjusting member 3 needs to be adjusted, the fastener 5 can be loosened so that the second end of the fastener 5 disengages from the first adjusting member, thereby allowing the second adjusting member 3 to move in the second direction. The fastener 5 can also move in the second mating groove in the second direction, making it easy to adjust the position of the second adjusting member 3. When the second adjusting member 3 is moved to the appropriate position, the fastener 5 can be tightened so that the second end of the fastener 5 abuts against the first adjusting member 2, thereby fixing the second adjusting member 3 and the first adjusting member 2, which facilitates the subsequent assembly of the lens module 20.

[0054] In some embodiments, the second adjusting member 3 may be provided with a third mating groove, which is parallel to and spaced apart from the third sliding groove 32. The third mating groove can penetrate through the opposite two sides of the second adjusting member 3. The connecting member 4 is provided with a third connecting hole. There are multiple fasteners 5, one of which can be movably inserted into the third mating groove. The first end and the second end of the fastener 5 are respectively located on opposite sides of the second adjusting member 3. The first end of the fastener 5 is threaded into the third connecting hole, and the second end of the fastener 5 is located on the side of the second adjusting member 3 facing away from the connecting member 4.

[0055] Thus, when the position of connector 4 needs to be adjusted, fastener 5 can be loosened so that the second end of fastener 5 disengages from the second adjustment, thereby allowing connector 4 to move in a third direction. Fastener 5 can also move in a third direction within the third mating groove, making it easy to adjust the position of connector 4. After connector 4 is moved to the appropriate position, fastener 5 can be tightened so that the second end of fastener 5 abuts against the second adjustment 3, thereby fixing connector 4 and the second adjustment 3, which facilitates the subsequent assembly of lens module 20.

[0056] Alternatively, the fastener 5 can be unscrewed from the connector 4 to disengage the connector 4 from the second adjusting member 3, making it easy to disassemble the connector 4. After replacing the connector 4, simply tighten the fastener 5 onto the connector 4 to install the connector 4 onto the second adjusting member 3, making it easy to replace the connector 4.

[0057] Please see Figure 1 and Figure 6 In some embodiments, the base plate 1 has a first side 13 and a second side 14 disposed opposite to each other. The first side 13 has a first sliding groove 11, and the second side 14 has a first mating groove 12. The first mating groove 12 communicates with the first sliding groove 11. The first slider 21 has a first connecting hole 23, which is disposed facing the first mating groove 12. The fastener 5 is used to connect the first slider 21 to the base plate 1.

[0058] Thus, the first mating groove 12 and the first sliding groove 11 are located on opposite sides of the base plate 1, and the first mating groove 12 and the first sliding groove 11 are interconnected. Therefore, when slotting on the base plate 1, the sum of the slotting depth of the first mating groove 12 and the slotting depth of the first sliding groove 11 is equal to the thickness of the base plate 1, which can reduce the slotting depth of the first mating groove 12, thereby reducing the slotting difficulty of the first mating groove 12 and reducing the slotting cost.

[0059] The first slider 21 has a first connecting hole 23, which allows the first end of the fastener 5 to be threaded into the first slider 21. When the first adjusting member 2 moves to the appropriate position, the fastener 5 can directly fix the first slider 21 to the base plate 1, making the first adjusting member 2 and the base plate 1 more stable.

[0060] In some embodiments, the second mating groove and the second sliding groove 22 are respectively located on opposite sides of the first adjusting member 2, and the second mating groove and the second sliding groove 22 are interconnected, and the second slider 31 has a second connecting hole. Similarly, the third mating groove and the third sliding groove 32 are respectively located on opposite sides of the second adjusting member 3, and the third mating groove and the third sliding groove 32 are interconnected, and the third slider 41 has a third connecting hole.

[0061] Please see Figure 6 In some embodiments, the fastener 5 includes a connecting rod 51 and a fastening head 52 connected to the connecting rod 51. The connecting rod 51 is threaded into the first connecting hole 23. The fastening head 52 is located in the first mating groove 12 and can rotate around the axis of the first connecting hole 23 in the first mating groove 12. The fastening head 52 is used to abut against the groove wall of the first mating groove 12 so that the first adjusting member 2 is fixed to the base plate 1.

[0062] It is understood that the width of the first mating groove 12 along the second direction is smaller than the width of the fastening head 52 along the second direction, so that the fastening head 52 can move along the first direction within the first mating groove 12, and the fastening head 52 can rotate within the first mating groove 12.

[0063] Thus, when adjusting the position of the first adjusting member 2, since the fastening head 52 can rotate around the axis of the first connecting hole 23 in the first mating groove 12, the connecting rod 51 can be rotated relative to the first connecting hole 23 by directly rotating the fastening head 52. Under the threaded engagement between the connecting rod 51 and the first connecting hole 23, the fastener 5 moves away from the first adjusting member 2, so that the fastening head 52 disengages from the groove wall of the first mating groove 12, so that the first adjusting member 2 can slide relative to the base plate 1 in the first direction.

[0064] After the first adjusting member 2 is moved to the appropriate position, the fastening head 52 can be directly rotated. Under the threaded engagement of the connecting rod 51 and the first connecting hole 23, the fastener 5 moves towards the first adjusting member 2, so that the fastening head 52 abuts against the groove wall of the first mating groove 12, thereby fixing the first adjusting member 2 to the base plate 1. The position of the first adjusting member 2 can be adjusted very conveniently.

[0065] Please see Figure 6In some embodiments, the first mating groove 12 includes a first groove bottom surface 121 and a first groove peripheral surface 122 connected to the first groove bottom surface 121. The fastening head 52 is used to abut against the first groove bottom surface 121 so that the first adjusting member 2 is fixed to the base plate 1.

[0066] Optionally, the first mating groove 12 is a square groove, and there is a channel between the bottom surface 121 of the first groove and the bottom surface of the first sliding groove 11 to connect the first mating groove 12 and the first sliding groove 11. The connecting rod 51 passes through the channel and can move in the first direction within the channel. The fastening head 52 is located in the first mating groove 12.
