Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of locking structures, and particularly relates to a locking structure for a battery compartment. BACKGROUND

[0002] Portable electronic instruments and devices, such as optical time domain reflectometers, metal flaw detectors, communication testers, etc., often use multiple rechargeable cylindrical lithium batteries (such as 18650 batteries) in series or parallel as a power supply. In order to accommodate such battery packs, a dedicated battery compartment is usually designed inside the device. In order to accommodate two to four batteries placed side by side, the cross section or opening is usually designed as an oblong or rectangular shape. The tail of the battery has a pull strap to facilitate the removal of the battery from the compartment. Such batteries have large capacity and long charging time, but the power consumption of the instrument is also large, and sometimes the power is exhausted and needs to be replaced on site, and the fixing method of the battery pack and the convenience of replacement become a problem in the design process of portable electronic instruments and devices.

[0003] In one design, the battery compartment is equipped with a battery cover, which is fixed to the device shell by screws, and then EVA foam or other elastic buffer materials are used to fill the gap between the battery pack and the battery cover. The above-mentioned screw locking method is relatively stable, but it is not convenient to disassemble during use, and the EVA foam or other elastic buffer materials are prone to permanent compression deformation, causing the battery to loosen in the battery compartment.

[0004] In another design, the battery compartment is equipped with a top cover using a bayonet design, and a metal spring is installed on the cover to hold the battery and fit the gap. The above-mentioned cover body using quick-release bayonet design generally uses complex molds, multiple parts are combined, and the assembly is complex, and for large-capacity battery packs, the weight is large, the design strength of the assembly parts composed of plastic, metal and spring is high, and the sliding fit relationship will also affect the service life, and it is easy to fail in complex field environment, and the cost will exceed the expectation.

[0005] As can be seen, the above designs generally have limited battery limiting ability, are not convenient for quick disassembly, or although they can be used in quick disassembly scenarios, the structure design is complex, the preparation cost is high, and the like.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a locking structure for a battery compartment. SUMMARY

[0007] The purpose of the present application is to provide a locking structure for a battery compartment, which can solve the problem of the simple battery compartment locking structure being not convenient for quick disassembly, and the complex locking structure being convenient for quick disassembly but having high cost and being difficult to prepare.

[0008] In order to achieve the above-mentioned purpose, the technical scheme provided by one embodiment of the present application is as follows:

[0009] A locking structure for a battery compartment, which can be assembled at a door of the battery compartment to lock a position of a battery, the locking structure comprising a locking unit including a first operation part and a second operation part opposite to each other, and a reset part connected between the first operation part and the second operation part, the first operation part and the second operation part being operatively adjustable in a distance therebetween;

[0010] The locking unit is provided with an abutting profile abutting against an inner side wall at the door of the battery compartment, an extension dimension of the locking unit defined by the abutting profile being changeable with the adjustment of the distance between the first operation part and the second operation part;

[0011] The first operation part and the second operation part have an initial distance, and the reset part has an elastic potential energy to reset the first operation part and the second operation part to the initial distance when the first operation part and the second operation part are operatively adjusted in the distance therebetween.

[0012] In one or more embodiments of the present application, the first operation part and the second operation part are operatively adjustable in a decrease in the distance therebetween, and the extension dimension of the locking unit is decreased with the decrease in the distance between the first operation part and the second operation part;

[0013] Alternatively, the first operation part and the second operation part are operatively adjustable in an increase in the distance therebetween, and the extension dimension of the locking unit is decreased with the increase in the distance between the first operation part and the second operation part.

[0014] In one or more embodiments of the present application, the reset part includes a bending spring connected between the first operation part and the second operation part.

[0015] When the first operation part and the second operation part are operatively adjusted in the distance therebetween, two ends of the bending spring are reversely moved in a misalignment to make the reset part have the elastic potential energy to reset the first operation part and the second operation part to the initial distance.

[0016] In one or more embodiments of the present application, the bending spring includes a first bending section and a second bending section opposite in bending direction, the first bending section being connected to the first operation part, and the second bending section being connected to the second operation part.

[0017] In one or more embodiments of the present application, the first bending section is directed toward the first operation part in the bending direction; and / or, the second bending section is directed toward the second operation part in the bending direction.

[0018] In one or more embodiments of the present application, the bending spring plate is provided with at least two and is arranged at intervals along the displacement direction of the first operation part and the second operation part.

[0019] In one or more embodiments of the present application, the first operation part is connected to one end of the bending spring plate through a first connecting part, the second operation part is connected to the other end of the bending spring plate through a second connecting part, the first connecting part is spaced apart from the second operation part, and the second connecting part is spaced apart from the first operation part.

[0020] In one or more embodiments of the present application, the first connecting part comprises a first abutting surface, and when the first operation part and the second operation part are operated to reduce the distance therebetween, the first abutting surface abuts against the second operation part to limit the maximum displacement of the first operation part and the second operation part; and / or,

[0021] The second connecting part comprises a first abutting surface, and when the first operation part and the second operation part are operated to reduce the distance therebetween, the first abutting surface abuts against the first operation part to limit the maximum displacement of the first operation part and the second operation part.

[0022] In one or more embodiments of the present application, one end of the first operation part away from the second operation part is provided with an abutting part, and the abutting part constitutes part of the abutting contour; and / or, one end of the second operation part away from the first operation part is provided with an abutting part, and the abutting part constitutes part of the abutting contour.

[0023] In one or more embodiments of the present application, the first operation part and the second operation part are provided with a taking and placing groove along the thickness direction of the locking structure; and / or, the first operation part and / or the second operation part are provided with an elastic pressing piece capable of pressing the battery in the battery compartment.

[0024] In one or more embodiments of the present application, the locking structure comprises two stacked locking units, the two locking units are fixed relative to each other, and the two locking units are stacked in a central symmetry manner so that the bending spring plates corresponding to each other in the two locking units have opposite bending directions.

[0026] The second abutting surface corresponding to one of the locking units can abut against the second abutting surface corresponding to the other one, so as to limit the maximum stretching distance between the first operation part and the second operation part.

[0027] Compared with the prior art, the battery compartment locking structure can change the extension size of the abutting contour of the locking unit by adjusting the distance between the first operation part and the second operation part, so as to be suitable for being assembled at the door of the battery compartment; in this process, the reset part accumulates elastic potential energy, and the elastic potential energy drives the first operation part and the second operation part to return to the initial distance, so that the abutting contour of the locking unit abuts against the inner wall of the door of the battery compartment, thereby filling the space of the door, locking the position of the battery and providing a buffer for the battery. It can be seen that, in the process of locking the battery, the operator only needs to adjust the distance between the first operation part and the second operation part, without other redundant operation steps, and the locking structure itself can be made of a material suitable for buffering and relatively not easy to be permanently deformed, so that a good balance is achieved in the complexity of the structure, the locking effect, the convenience of disassembly and assembly and the like.

DETAILED DESCRIPTION

[0036] In order to make the personnel in the technical field better understand the technical solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by the person of ordinary skill in the art without making creative efforts should belong to the protection scope of the present disclosure.

[0037] In portable electronic devices, a power supply system is often composed of multiple cylindrical lithium batteries, and for this purpose, a corresponding battery compartment needs to be provided in the device. In order to accommodate two to four batteries arranged side by side, the cross section or opening of the battery compartment is usually designed as an oblong or rectangular shape. Since such batteries have large capacity and long charging time, and the device itself has high power consumption, the batteries often need to be replaced on site after the power is depleted. Therefore, how to achieve stable fixation and quick replacement of the battery pack has become a key challenge in the design of such portable devices.

[0038] In the design of the battery compartment provided with a battery cover described above, the battery cover is inconvenient to disassemble and assemble, and the battery is prone to loosen in the compartment after long-term use. In the design of the top cover with a bayonet structure and the metal spring piece mounted on the cover described above, the structure is complex, and the manufacturing cost is increased.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 is an explosion schematic view of the locking structure for the battery compartment, the battery compartment and the battery in an embodiment of the present disclosure, Figure 2 is an assembly schematic view of the locking structure for the battery compartment, the battery compartment and the battery in an embodiment of the present disclosure. Figure 1 and Figure 2 The locking structure for the battery compartment in the present application is indicated by mark a, the battery compartment in the present application is indicated by mark b, and the battery in the present application is indicated by mark c.

[0040] Based on the above problems, please refer to Figure 1 and Figure 2The battery compartment locking structure can be precisely and complementarily attached to the space at the door of the battery compartment, has the beneficial effect of quick disassembly and assembly, can lock the battery in the battery compartment and provide excellent buffering for the battery. When the battery needs to be replaced, it can be quickly unlocked and taken out from the battery compartment; when the battery is placed in the battery compartment, it can be quickly installed in the battery compartment to lock the battery in the battery compartment and provide excellent buffering for the battery. The locking structure of the application can be used alone or in combination with a battery cover that can be quickly opened and closed to improve the convenience of battery replacement.

[0041] The basic concept of the battery compartment locking structure of the application is that the locking structure includes a locking unit, the locking unit includes a first operating part and a second operating part opposite to each other, and a reset part connected between the first operating part and the second operating part, and the locking unit is provided with an abutting contour that can abut against the inner side wall of the door of the battery compartment. When the distance between the first operating part and the second operating part is operated, the extension size defined by the abutting contour of the locking unit changes, so that it is suitable for being fitted to the door of the battery compartment; in this process, the reset part accumulates elastic potential energy, which has the elastic potential energy to drive the first operating part and the second operating part to reset to the initial distance, so that the abutting contour of the locking unit abuts against the inner side wall of the door of the battery compartment, thereby filling the space at the door, locking the position of the battery and providing buffering for the battery. It can be seen that in the process of locking the battery, the operator only needs to operate the distance between the first operating part and the second operating part, without other redundant operation steps, and the locking structure itself can also be made of a material suitable for buffering and relatively not easy to permanently deform, achieving a good balance in the complexity of the structure, the locking effect, the convenience of disassembly and assembly, etc.

[0042] The battery compartment locking structure of the application will be specifically introduced below in combination with specific embodiments.

[0043] Please refer to Figure 2 and Figure 3 , Figure 3 is a structural schematic view of the battery compartment locking structure in an embodiment of the application. The battery compartment locking structure in the embodiment of the application can be fitted to the door of the battery compartment to lock the position of the battery. The locking structure includes a locking unit, the locking unit includes a first operating part 1 and a second operating part 2 opposite to each other, and a reset part 3 connected between the first operating part 1 and the second operating part 2, and the first operating part 1 and the second operating part 2 can be operated to adjust the distance between them.

[0044] The locking unit is provided with an abutting profile which can abut against the inner side wall of the door of the battery compartment, and the extension size of the locking unit defined by the abutting profile can be changed with the adjustment of the distance between the first operating part 1 and the second operating part 2; wherein the locking unit can be mounted on the inner side wall of the door of the battery compartment, and the abutting profile is at least part of the profile of the locking unit which is used to abut against the inner side wall of the door of the battery compartment. In examples, it can be the whole profile of the locking unit, or it can be part of the profile of the locking unit.

[0045] The first operating part 1 and the second operating part 2 have an initial distance, and the reset part 3 has the elastic potential energy to reset the first operating part 1 and the second operating part 2 to the initial distance when the distance between the first operating part 1 and the second operating part 2 is adjusted by operation. The initial distance is the distance between the first operating part 1 and the second operating part 2 when the reset part 3 does not accumulate the elastic potential energy. Therefore, when the distance between the first operating part 1 and the second operating part 2 is adjusted, the extension size of the abutting profile of the locking unit can be changed, so as to be suitable for being fitted to the door of the battery compartment. In this process, the reset part 3 accumulates the elastic potential energy, and has the elastic potential energy to drive the first operating part 1 and the second operating part 2 to reset to the initial distance. When the external operation force is released, the abutting profile of the locking unit can be tightly abutted against the inner wall of the battery compartment by the elastic potential energy of the reset part 3, so as to fix the locking structure in the battery compartment, thereby locking the position of the battery and providing the buffer for the battery. It can be seen that in the process of locking the battery, the operator only needs to adjust the distance between the first operating part 1 and the second operating part 2, without other redundant operation steps, so that the locking structure can be quickly disassembled and assembled, and the battery can be quickly replaced.

[0046] Please refer to Figure 3 , wherein the first operating part 1 and the second operating part 2 are provided with a taking and placing groove 4 in the thickness direction of the locking structure. When in use, the operator only needs to insert the fingers into the taking and placing groove 4, and the distance between the first operating part 1 and the second operating part 2 can be adjusted by pinching or pushing and pulling, so that the locking structure can be quickly fitted in the battery compartment or taken out from the battery compartment.

[0047] Please refer to Figure 3 and Figure 4 , Figure 4 is a top view of the locking structure for the battery compartment in an embodiment of the present application. The first operating part 1 and the second operating part 2 can be operated to reduce the distance therebetween, and the extension size of the locking unit is reduced with the reduction of the distance between the first operating part 1 and the second operating part 2. In this embodiment, the extension size of the locking unit is the size of the extension in the direction in which the first operating part 1 and the second operating part 2 can be operated to move, and the direction in which the first operating part 1 and the second operating part 2 can be operated to move can be referred to Figure 4The direction corresponding to the X-axis direction. Based on this, the abutting outer contour is arranged at the two ends of the displacement direction in which the first operating part 1 and the second operating part 2 of the locking unit can be operated, so that the two ends of the locking unit abut against the inner wall of the battery compartment to achieve the fixation of the locking structure itself.

[0048] Specifically, when the operation makes the distance between the first operating part 1 and the second operating part 2 decrease, the extension size of the locking unit correspondingly decreases, at this time the locking unit can be placed in the battery compartment. When the operating force is released, the extension size of the locking unit increases under the action of the reset part 3, so that the abutting outer contour of the locking unit abuts against the inner wall of the battery compartment to complete the quick installation of the locking unit. Similarly, when the operation continues to make the distance between the first operating part 1 and the second operating part 2 decrease, the extension size of the locking unit correspondingly decreases, and the abutting outer contour of the locking unit is away from the inner wall of the battery compartment, at this time the locking unit can be taken out from the battery compartment.

[0049] Please refer to Figure 3 and Figure 4 , one end of the first operating part 1 away from the second operating part 2 is provided with an abutting part 5, and the abutting part 5 constitutes part of the abutting outer contour; and / or, one end of the second operating part 2 away from the first operating part 1 is provided with an abutting part 5, and the abutting part 5 constitutes part of the abutting outer contour. In the embodiment, the first operating part 1 and the second operating part 2 can be provided with the above-mentioned abutting part 5, which can be adapted to the shape of the inner wall of the battery compartment and abut against the inner wall of the battery compartment, so that the locking structure is fixed in the battery compartment under the action of the reset part 3 to lock the position of the battery and provide buffer for the battery. It can be understood that the shape and number of the abutting part 5 can be adjusted according to the shape of the battery compartment, so that it can be tightly abutted against the inner wall of the battery compartment, and the present application does not limit this.

[0050] In the present application, the reset part 3 has an elastic potential energy for resetting the first operating part 1 and the second operating part 2 to the initial distance. It can cooperate with the first operating part 1 and the second operating part 2 to realize the quick disassembly and assembly of the locking structure, and the reset part 3 of the present application will be described in detail below.

[0051] Please refer to Figure 3 and Figure 4, the reset part 3 comprises a bent elastic sheet 31 connected between the first operating part 1 and the second operating part 2; when the first operating part 1 and the second operating part 2 are operated to adjust the interval therebetween, the two ends of the bent elastic sheet 31 are reversely moved in dislocation, so that the reset part 3 has the elastic potential energy to reset the first operating part 1 and the second operating part 2 to the initial interval. Therefore, when the interval between the first operating part 1 and the second operating part 2 is adjusted, the bent elastic sheet 31 has the tendency to be straightened, thereby accumulating the elastic potential energy. When the locking structure is placed in the battery compartment and the operating force is released, the bent elastic sheet 31 has the elastic potential energy of the initial curved state when it is restored, which can make the abutting profile of the locking unit tightly abut against the inner side wall of the battery compartment, so as to realize the quick disassembly of the locking structure.

[0052] Please refer to Figure 4 , specifically, the bent elastic sheet 31 comprises a first bent section 311 and a second bent section 312 with opposite bending directions, the first bent section 311 is connected to the first operating part 1, and the second bent section 312 is connected to the second operating part 2. The bending direction of the first bent section 311 is towards the first operating part 1; and / or, the bending direction of the second bent section 312 is towards the second operating part 2. In the embodiment, the boundary line between the first bent section 311 and the second bent section 312 can specifically refer to the dotted line in Figure 4 . The above structure can make the operator more labor-saving when pinching the first operating part 1 and the second operating part 2. In the embodiment, the bent elastic sheet 31 comprises two sections of the first bent section 311 and the second bent section 312 with opposite bending directions, in other embodiments, the first bent section 311 and the second bent section 312 can also be alternately arranged in multiple sections, which is not limited in the application.

[0053] Please refer to Figure 3 and Figure 4 , the bent elastic sheet 31 is provided with at least two and is arranged in interval along the displacement direction of the first operating part 1 and the second operating part 2 which can be operated. The displacement direction of the first operating part 1 and the second operating part 2 which can be operated can specifically refer to the direction of the X-axis in Figure 4 . In the embodiment, the bent elastic sheet 31 is provided with four, and in other embodiments, the number can also be two, three, five or even more, which is not limited in the application. By arranging a certain number of bent elastic sheets 31, the elastic potential energy accumulated thereby can be greater, so that the abutting force of the abutting profile of the locking unit and the inner side wall of the battery compartment is greater, which can ensure that the locking structure is tightly fixed in the battery compartment to lock the position of the battery and provide excellent buffer for the battery.

[0054] Please refer to Figure 3 and Figure 4Further, the first operation part 1 is connected to one end of the bending spring 31 through the first connecting part 6, and the second operation part 2 is connected to the other end of the bending spring 31 through the second connecting part 7. The first connecting part 6 is spaced apart from the second operation part 2, and the second connecting part 7 is spaced apart from the first operation part 1. The first connecting part 6 and the second connecting part 7 are arranged on both sides of a reference line, which is a line connecting the centers of the first operation part 1 and the second operation part 2. The reference line can be a dashed line as shown in FIG. 8. Figure 4 The first connecting part 6, the second connecting part 7 and the bending spring 31 are arranged such that the bending spring 31 is located on the reference line. This makes it easier to pinch and push and pull the first operation part 1 and the second operation part 2, and makes the force on the locking structure more balanced.

[0055] Please refer to Figure 3 and Figure 4 The first connecting part 6 includes a first abutting surface 81 that abuts against the second operation part 2 to limit the maximum displacement of the first operation part 1 and the second operation part 2 when the first operation part 1 and the second operation part 2 are operated to reduce the distance between them. The second connecting part 7 also includes a first abutting surface 81 that abuts against the first operation part 1 to limit the maximum displacement of the first operation part 1 and the second operation part 2 when the first operation part 1 and the second operation part 2 are operated to reduce the distance between them. In this embodiment, both the first connecting part 6 and the second connecting part 7 include the first abutting surface 81. In other embodiments, only one of the first connecting part 6 and the second connecting part 7 includes the first abutting surface 81. When the distance between the first operation part 1 and the second operation part 2 is adjusted, the first abutting surface 81 abuts against the first operation part 1 and / or the second operation part 2 to limit the maximum displacement of the first operation part 1 and the second operation part 2. Limiting the maximum displacement of the first operation part 1 and the second operation part 2 prevents the locking structure from being torn or damaged due to excessive force.

[0056] The first operation part 1, the second operation part 2, the first connecting part 6, the second connecting part 7 and the reset part 3 are integrally formed by a flexible material. For example, the flexible material can be nylon PA12 material, or EVA with excellent strength and durability. The integral forming can be 3D printing by SLS process. The locking structure of the present application does not need extra parts, and the above-mentioned method reduces the assembly cost. By modifying the shape of the locking unit, the adaptability to different battery compartments can be improved. The flexible material can effectively improve the convenience of adjusting the distance between the first operation part 1 and the second operation part 2. At the same time, it can provide good elastic buffer for the battery in the battery compartment, and provide safety guarantee for the fixation of the battery pack. The locking structure is made of the above-mentioned flexible material, which achieves a good balance in complexity, locking effect, and convenience of disassembly.

[0057] Please refer to Figure 4 The first operation part 1 and / or the second operation part 2 are provided with an elastic pressing piece 9 which can press the battery in the battery compartment. It can further press the position of the battery in the battery compartment, so as to avoid the battery from shaking in the battery compartment, and maintain the normal use of the instrument.

[0058] Please refer to Figure 5 In another optional embodiment, the first operation part 1 and the second operation part 2 can be operated to increase the distance between them, and the extension size of the locking unit decreases with the increase of the distance between the first operation part 1 and the second operation part 2. The abutting contour is arranged between the first operation part 1 and the second operation part 2, and when the first operation part 1 and the second operation part 2 are operated to increase the distance between them, the displacement direction of the first operation part 1 and the second operation part 2 can intersect with the size extension direction of the abutting contour. In this embodiment, the size extension direction of the abutting contour can be substantially perpendicular to the displacement direction of the first operation part 1 and the second operation part 2. The size extension direction of the abutting contour can refer to the direction corresponding to the Y axis in Figure 5 , and the displacement direction of the first operation part 1 and the second operation part 2 can refer to the direction corresponding to the X axis in Figure 5 .

[0059] In the example, the first connecting portion 6 and the second connecting portion 7 can be bent, or the first connecting portion 6 and the second connecting portion 7 can be thickened to increase the extension size of the locking unit in the Y-axis direction. When the distance between the first operating portion 1 and the second operating portion 2 is increased, the extension size of the locking unit in the Y-axis direction is correspondingly reduced, and the locking unit can be placed in the battery compartment. When the operating force is released, the extension size of the locking unit is increased under the action of the reset portion 3, and the locking unit can abut against the inner side wall of the battery compartment in the Y-axis direction to complete the quick installation of the locking unit. Specifically, the corresponding abutting profiles of the first connecting portion 6 and the second connecting portion 7 can abut against the inner side wall of the battery compartment. Similarly, when the distance between the first operating portion 1 and the second operating portion 2 is increased, the extension size of the locking unit in the Y-axis direction is correspondingly reduced, and the abutting profiles are away from the inner side wall of the battery compartment to complete the quick removal of the locking unit.

[0060] Please refer to Figure 3 The locking structure includes two stacked locking units, and the two locking units are fixed relative to each other. Specifically, a connecting rib 10 can be arranged between the two locking units to fix the two locking units relative to each other. The connecting rib 10 can also be integrally formed with the two locking units by using the same material to improve the convenience of manufacturing the locking structure. It can be understood that in other embodiments, the two locking units can also be fixed relative to each other by other means, such as adhesion, insertion, etc.

[0061] Please refer to Figure 3 and Figure 4 The reset portion 3 includes the above-mentioned bent elastic sheet 31 connected between the first operating portion 1 and the second operating portion 2. The two locking units are centrally symmetrically stacked to make the corresponding bent elastic sheets 31 of the two locking units have opposite bending directions. In this case, the first operating portion 1 and the second operating portion 2 of the two locking units are correspondingly arranged in the up-down direction. When the first operating portion 1 and the second operating portion 2 are pressed or pulled, the locking structure can be twisted and offset due to the shape and position of the bent elastic sheet 31. In this embodiment, the two locking units are arranged in a central symmetric manner, and the twisting forces of the two locking units are opposite and can be offset, so that the first operating portion 1 and the second operating portion 2 can move as much as possible in the X direction, which is more convenient for operation. Therefore, by using the double-layer stacked locking units and the bent elastic sheet 31, the locking structure can be compressed in the X direction without twisting, so that the locking structure can be directly assembled into the battery compartment, and the locking structure can be unlocked in a very intuitive two-finger pinching manner, which improves the convenience of use.

[0062] Please refer to Figure 3 and Figure 4The first operation part 1 is connected to one end of the bent elastic sheet 31 through the first connecting part 6, and the second operation part 2 is connected to the other end of the bent elastic sheet 31 through the second connecting part 7, and the first connecting part 6 and / or the second connecting part 7 each comprises a second abutting surface 82 bent and extended along the stacking direction; one of the two locking units corresponds to the second abutting surface 82 which can abut against the second abutting surface 82 of the other one of the two locking units to limit the maximum stretching distance between the first operation part 1 and the second operation part 2. It can be understood that when the first operation part 1 and the second operation part 2 are stretched, the second abutting surface 82 of the first connecting part 6 of one of the two locking units can abut against the second abutting surface 82 of the first connecting part 6 of the other one of the two locking units; and / or, the second abutting surface 82 of the second connecting part 7 of one of the two locking units can abut against the second abutting surface 82 of the second connecting part 7 of the other one of the two locking units. Therefore, through the mutual interference of the two second abutting surfaces 82, it can avoid the excessive stretching of the first operation part 1 and the second operation part 2, so as to avoid the tearing or damage of the locking structure.
