Description

Technical Field

[0001] This utility model relates to the field of electronic component fixtures, and in particular to an electronic component assembly fixture. Background Technology

[0002] Sensors are common electronic components in daily life. They mainly identify targets such as objects, people, or physical quantities, and output signals based on the identification results to trigger relevant components to execute corresponding instructions, thus meeting different practical needs in daily use.

[0003] Currently, most sensors are internally composed of pins, circuit boards, electrode plates, and shielding rings. During assembly, the pins, circuit boards, and electrode plates are first aligned and then soldered sequentially. Next, the shielding ring, which is fitted onto the circuit board, is moved to the outside of the electrode plates, hiding them inside the shielding ring. Finally, the shielding ring is soldered onto the circuit board. In this assembly process, each pair of components requires a different assembly fixture for relative fixation to ensure relative positioning accuracy. Due to the presence of multiple components, multiple assembly fixtures are needed to fix different pairs of components. The sensor's detection distance and sensitivity are inextricably linked to the relative accuracy of adjacent components. Each time the assembly fixture is changed, the sensor's positioning reference changes, causing a deviation in the positioning reference accuracy for each pair of components. This affects the sensor's detection distance and sensitivity. Furthermore, the cumulative deviation of the positioning reference leads to significant accuracy errors in the finished product, impacting the sensor's production quality and batch yield. Utility Model Content

[0004] The purpose of this utility model is to provide an electronic component assembly fixture that can simultaneously clamp three types of electrical components and make the three types of components abut against each other in sequence with the same positioning reference, so as to avoid the generation of multiple positioning references.

[0006] In the above-mentioned electronic component assembly fixture, the limiting component includes two limiting members disposed on the frame, and the first positioning part, the second positioning part, the third positioning part and the push-pull member are all disposed between the two limiting members.

[0007] In the above-mentioned electronic component assembly fixture, two guide posts are connected between the first and second sides of the frame. The first slider and the second slider are both sleeved on the two guide posts and are slidably engaged with the two guide posts. The two guide posts correspond one-to-one with the two limiting members, and the limiting members are sleeved on the corresponding guide posts.

[0008] In the aforementioned electronic component assembly fixture, the push-pull member slides in conjunction with the frame, and the locking assembly includes a first connecting rod and an L-shaped second connecting rod. The corner of the second connecting rod is hinged to one end of the first connecting rod, and the other end of the first connecting rod faces the push-pull member and is hinged to the frame. One end of the second connecting rod is hinged to the push-pull member, and a limiting part is provided on the first connecting rod.

[0009] In the aforementioned electronic component assembly fixture, the frame is provided with a detachable clamping member, and the first slider, the clamping member, and the second side of the frame abut against each other in sequence.

[0010] In the above-mentioned electronic component assembly fixture, the frame is provided with a first insert, the first positioning part is a positioning recess provided on the first insert and open towards the second slider; the first slider is provided with a second insert, the second positioning part is a positioning insertion hole provided on the second insert and open towards the second slider; the third positioning part is a positioning slot formed on the outer surface of the second slider.

[0011] In the above-mentioned electronic component assembly fixture, one side of the first insert is provided with a first positioning hook for pressing the component onto the positioning recess. The hook handle of the first positioning hook passes through the first side of the frame in a clearance fit and extends to the outside of the frame. A first end cap is provided at the end of the hook handle of the first positioning hook. A first compression spring abuts between the first end cap and the frame. The first compression spring is sleeved on the hook handle of the first positioning hook.

[0012] In the above-mentioned electronic component assembly fixture, a second positioning hook is provided on one side of the second insert for pressing the component into the positioning socket. The hook shank of the second positioning hook passes through the first slider in a clearance fit and extends to the second side between the first slider and the frame. A second end cap is provided at the end of the hook shank of the second positioning hook. A second compression spring abuts between the second end cap and the first slider. The second compression spring is sleeved on the hook shank of the second positioning hook.

[0013] In the aforementioned electronic component assembly fixture, one side of the positioning slot is provided with a cover plate for pressing the component onto the second slider, and the cover plate is detachably connected to the second slider.

[0014] The aforementioned electronic component assembly fixture also includes a base plate, on which a first positioning block and two second positioning blocks are provided. The frame is positioned between the two second positioning blocks, and the outer side of the first side of the frame abuts against the first positioning block.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0016] The technical solution comprises a first slider and a second slider within a frame. The first and second sliders can reciprocate in the same direction within the frame, moving away from or towards a first side of the frame. A first positioning part is provided on the first side of the frame, and a first component is mounted on the first positioning part. A second positioning part is provided on the first slider, and a third positioning part is provided on the second slider. A second component is mounted on the second positioning part, and a third component is mounted on the third positioning part. In use, by pushing the push-pull component on the first slider, the first slider is driven to move towards the second slider. As the first slider moves, the second component gradually moves closer to the third component. With the movement of the first slider, the limiting component located between the first and second sliders is pressed against the second slider by the first slider, pushing the second slider towards the first positioning part. At this time, a gap space is formed between the first and second sliders, and the second and third components abut within this gap space. As the second slider moves, the third component gradually approaches the first component, while the limiting component located between the second slider and the first side of the frame is squeezed by the second slider and abuts against the first side of the frame. At this time, a gap space is formed between the second slider and the first side of the frame, and the third component abuts against the first component within this gap space. Finally, by switching the locking component to the locking state, the push-pull component and the frame are relatively fixed, and then the three components are welded together. When disassembling the finished product (with a fourth component welded on), first restore the locking assembly to its initial state, allowing the push-pull component to move relative to the frame. Pulling the push-pull component in the opposite direction causes the first slider to retract. Since the second component is fixed to the third component, it disengages from the second positioning part as the first slider retracts. Then, moving the second slider causes the third component to retract. Since the first component is fixed to the third component, the second slider causes both the third and first components to retract together, disengaging the first component from the first positioning part. At this point, other components are fixed to the third component. Finally, the third component is removed from the second slider, resulting in the assembled product. This assembly fixture simultaneously clamps three types of electrical components, ensuring they abut against each other sequentially using the same positioning reference. This avoids multiple positioning references, reducing the impact of detection distance and sensitivity, and improving production quality and batch pass rate. Attached Figure Description

[0028] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0029] Example 1:

[0030] like Figure 1 - Figure 6As shown, the electronic component assembly fixture includes a frame 3. A first positioning part 3011 is provided on the inner side of the first side of the frame 3. A first slider 10 for moving away from or towards the first positioning part 3011 is provided on one side of the first positioning part 3011. The first slider 10 is located inside the frame 3 and slides in cooperation with the frame 3. A second positioning part 10011 is provided on the side of the first slider 10 adjacent to the first positioning part 3011. Two limiting components and a reciprocating second slider 6 are provided between the first slider 10 and the first side of the frame 3. The second slider 6 is located between the two limiting components and slides with the frame 3; the limiting components are all fixed on the frame 3; the second slider 6 is provided with a third positioning part 603, which is respectively provided with the first positioning part 3011 and the second positioning part 10011; the first slider 10 is provided with a push-pull member 11 that passes through the second side of the frame 3; the second side and the first side of the frame 3 are opposite sides of the frame 3; the push-pull member 11 is arranged to move relative to the frame 3 along its axial direction; a locking component is provided between the push-pull member 11 and the frame 3.

[0031] The specific working principle is as follows: a first slider 10 and a second slider 6 are provided inside the frame 3. The first slider 10 and the second slider 6 can reciprocate in the same direction within the frame 3, that is, they can move away from or closer to the first side of the frame 3. A first positioning part 3011 is provided on the first side of the frame 3. A first component is installed on the first positioning part 3011. A second positioning part 10011 is provided on the first slider 10. A third positioning part 603 is provided on the second slider 6. A second component is installed on the second positioning part 10011. A third component is installed on the third positioning part 603. In use, by pushing the push-pull member 11 on the first slider 10, the first slider 10 is driven to move towards the second slider 6. As the first slider 10 moves, the second component gradually approaches the third component. With the movement of the first slider 10, the limiting component located between the first slider 10 and the second slider 6 is pressed against the second slider 6 by the first slider 10, pushing the second slider 6 towards the first positioning part 3011. At this time, a gap space is formed between the first slider 10 and the second slider 6, and the second and third components abut against each other within this gap space. As the second slider 6 moves, the third component gradually approaches the first component, and the limiting component located between the second slider 6 and the first side of the frame 3 is pressed against the first side of the frame 3 by the second slider 6. At this time, a gap space is formed between the second slider 6 and the first side of the frame 3, and the third component abuts against the first component within this gap space. Finally, by switching the locking component to the locking state, the push-pull member 11 and the frame 3 are relatively fixed, and then the three components are welded together. When disassembling the finished product (with the fourth component welded on), first restore the locking assembly to its initial state so that the push-pull component 11 can move relative to the frame 3. As the push-pull component 11 is pulled in the opposite direction, the first slider 10 is moved backward. Since the second component is fixed on the third component, the second component disengages from the second positioning part 10011 when the first slider 10 retracts. Then, the second slider 6 is moved to move the third component backward. Since the first component is fixed on the third component, the second slider 6 moves the third component and the first component backward together, and the first component disengages from the first positioning part 3011. At this time, other components are fixed on the third component. Finally, the third component is removed from the second slider 6, and the assembled finished product is obtained. This realizes that the assembly fixture can simultaneously clamp three types of electrical components and make the three types of components abut against each other in sequence with the same positioning reference, so as to avoid the generation of multiple positioning references. This reduces the impact of detection distance and sensitivity, and also improves production quality and batch pass rate.

[0032] In this embodiment, the third and fourth sides of the frame 3 are opposite sides of the frame 3. The first, third, second, and fourth sides of the frame 3 are connected end to end to form a frame structure. Guide rails are provided on the third and fourth sides of the frame 3. One end of each guide rail extends to the first side of the frame 3, and the other end extends to the second side of the frame 3. The first slider 10 and the second slider 6 are both located between the two guide rails and are slidably engaged with the two guide rails. Each end of the first slider 10 and the second slider 6 is provided with a sliding end block corresponding to the two guide rails. The sliding end block is slidably engaged with the corresponding guide rail. For example, each end of the first slider 10 is provided with a first sliding end block 1002, and the two first sliding end blocks 1002 are slidably engaged with the two guide rails. Each end of the second slider 6 is provided with a second sliding end block 602, and the two second sliding end blocks 602 are slidably engaged with the two guide rails.

[0033] In practical applications, this assembly fixture can be used not only to assemble sensor components, but also to assemble components of other electrical components. This embodiment does not impose too many restrictions on this.

[0034] The specific structure of the limiting component is as follows: the limiting component includes two limiting members 302 disposed on the frame 3, and the first positioning part 3011, the second positioning part 10011, the third positioning part 603 and the push-pull member 11 are all disposed between the two limiting members 302.

[0035] In some embodiments, the limiting member 302 is a top block. During the assembly of the fixture, one top block in the limiting unit is connected to the third side of the frame 3, and the other top block in the limiting unit is connected to the fourth side of the frame 3.

[0036] In other embodiments, the two top blocks in the limiting unit may also be fixed on the first slider 10 or the second slider 6, or one top block of the limiting unit may be fixed on the first slider 10 and the other top block of the limiting unit may be fixed on the second slider 6.

[0037] In this embodiment, two guide posts 303 are connected between the first side and the second side of the frame 3. The first slider 10 and the second slider 6 are both sleeved on the two guide posts 303 and are slidably engaged with the two guide posts 303. The two guide posts 303 correspond one-to-one with two limiting members 302, and the limiting members 302 are sleeved on the corresponding guide posts 303.

[0038] In the specific configuration, the limiting member 302 is a cylindrical structure with open ends and is sleeved on the guide post 303. The guide post 303 is connected between the first and second sides of the frame 3. The first slider 10 and the second slider 6 are both slidably engaged with the frame 3 (specifically the third and fourth sides of the frame 3) and also slidably engaged with the two guide posts 303. This improves the movement stability and movement pointing accuracy of the first slider 10 and the second slider 6, thereby reducing the accuracy error of their relative positioning. In practical applications, the two sliding end blocks on the first slider 10 correspond one-to-one with the two guide posts 303 and are slidably engaged, and the two sliding end blocks on the second slider 6 correspond one-to-one with the two guide posts 303 and are slidably engaged. The combination of the cylindrical limiting member 302 and the guide post 303 avoids the limiting member 302 being rigidly connected and fixed to the frame 3, reducing the processing difficulty and saving the production time of the processing and assembly fixture.

[0039] In this preferred embodiment, the limiting member 302 is a buffer spring.

[0040] The two buffer springs located between the first slider 10 and the second slider 6 can not only push the second slider 6 to move under the compression of the first slider 10 and create a gap between the first slider 10 and the second slider 6, but also absorb excess force and impact through the compression deformation of the buffer springs themselves, thus preventing the second component from colliding violently with the third component. Similarly, the two buffer springs located between the second slider 6 and the first side of the frame 3 can not only create a gap between the second slider 6 and the first side of the frame 3, but also prevent the third component from colliding violently with the first component.

[0041] like Figure 2 As shown, the specific structure of the locking assembly is as follows: the push-pull member 11 is slidably engaged with the frame 3. The locking assembly includes a first connecting rod 12 and an L-shaped second connecting rod 13. The corner of the second connecting rod 13 is hinged to one end of the first connecting rod 12. The other end of the first connecting rod 12 is directly opposite the push-pull member 11 and is hinged to the frame 3. One end of the second connecting rod 13 is hinged to the push-pull member 11. A limiting part 1201 is provided on the first connecting rod 12.

[0042] When the locking assembly is in the locked state, the first connecting rod 12, hinged to the frame 3, is directly opposite and parallel to the push-pull member 11; the corner of the second connecting rod 13 is located outside the outer end of the push-pull member 11 and is on the axis of the push-pull member 11; one end of the second connecting rod 13 is a wrench end 1301, which serves as the point of force for rotating the second connecting rod 13 and is pushed by external force. In some preferred embodiments, the wrench end 1301 is provided with a handle 14, wherein the wrench end 1301 is specifically located on one side of the push-pull member 11 and intersects with the push-pull member 11; the other end of the second connecting rod 13 is a connecting end 1302, which is hinged to the first connecting rod 12 and... The second link 13 abuts against the limiting part 1201, which is specifically located on the opposite side of the push-pull member 11. The connecting end 1302 is also directly opposite and parallel to the push-pull member 11, making the corner of the second link 13 a dead point of the movement of the first link 12 (specifically, the hinge fulcrum between the first link 12 and the frame 3) and the connecting end 1302 (specifically, the hinge fulcrum between the connecting end 1302 and the push-pull member 11). When there is no external force pushing the wrench end 1301, the corner of the second link 13 causes the second link 13 to remain relatively fixed to the frame 3 through the first link 12, thereby fixing the push-pull member 11 to the frame 3. At this time, the locking assembly is in a locked state.

[0043] like Figure 5 As shown, when the locking assembly is in its initial state, the first link 12, hinged to the frame 3, is also directly opposite and parallel to the push-pull member 11; the corner of the second link 13 is located between the limiting part 1201 and the outer end of the push-pull member 11 (specifically, the hinge fulcrum between the push-pull member 11 and the connecting end 1302), and is directly opposite the push-pull member 11; the wrench end 1301 and the limiting part 1201 are both located on the same side of the push-pull member 11, the wrench end 1301 abuts against the limiting part 1201 and intersects with the push-pull member 11, while the connecting end 1302... The second link 13 is directly opposite and parallel to the push-pull member 11. Therefore, the corner of the second link 13 becomes the dead point of the movement of the push-pull member 11 (specifically, the hinge fulcrum between the push-pull member 11 and the connecting end 1302) and the first link 12 (specifically, the hinge fulcrum between the first link 12 and the frame 3). When there is no external force pushing the wrench end 1301, the corner of the second link 13 causes the second link 13 to remain relatively fixed to the frame 3 through the first link 12, and similarly makes the push-pull member 11 relatively fixed to the frame 3. At this time, the locking assembly is in the initial state.

[0044] During the transition of the locking assembly from the initial state to the locked state and from the locked state to the initial state, the first link 12 swings outward toward the push-pull member 11 around the hinge fulcrum (specifically, the hinge fulcrum between the first link 12 and the frame 3) until the corner of the second link 13 and the connecting end 1302 exchange relative positions. If the locking assembly is in the locked state, the corner of the second link 13, the connecting end 1302 and the frame 3 are arranged in sequence, or if the locking assembly is in the initial state, the connecting end 1302, the corner of the second link 13 and the frame 3 are arranged in sequence.

[0045] In some embodiments, the push-pull member 11 is threadedly connected to the frame 3 in an adjustable manner along its axial direction, and the locking assembly includes two locking nuts, one of which, the other of which abuts against the frame 3 (specifically, the outer side of the second side of the frame 3).

[0046] Further improvements include a detachable clamping component on the frame 3, with the first slider 10 and the clamping component abutting against the second side of the frame 3 in sequence.

[0047] The clamping element is designed so that after the first slider 10 and the second slider 6 are locked onto the frame 3 by the locking assembly, the clamping element can be installed to abut against the second side of the first slider 10 and the frame 3, thereby strengthening the locking effect and meeting the production needs of moving or flipping the assembly fixture, thus improving practicality.

[0048] In the specific configuration, the side of the clamping member is provided with an opening for installation and disassembly. The opening connects the inner and outer sides of the clamping member and extends to both ends of the clamping member. The clamping member is sleeved on a guide post 303.

[0049] In some embodiments, recesses are provided on the adjacent sides of the second side of the first slider 10 and the frame 3, and the two ends of the clamping member correspond one-to-one with the two recesses. The ends of the clamping members are engaged in the corresponding recesses and abut against the corresponding recesses.

[0050] In this embodiment, the frame 3 is provided with a first insert 301, and the first positioning part 3011 is a positioning recess provided on the first insert 301 and open towards the second slider 6; the first slider 10 is provided with a second insert 1001, and the second positioning part 10011 is a positioning insertion hole provided on the second insert 1001 and open towards the second slider 6; the third positioning part 603 is a positioning slot formed on the outer surface of the second slider 6.

[0051] In practical applications, this embodiment uses the electrode plate 4 as the first component, the pin 9 as the second component, the circuit board 5 as the third component, and the shielding ring 8 as the fourth component for illustration. That is, the electrode plate 4 corresponds to the positioning recess, the pin 9 corresponds to the positioning hole, and the circuit board 5 corresponds to the positioning slot. In addition, the first component can also be any component other than the electrode plate 4. Similarly, the second component can also be any component other than the pin 9, the third component can also be any component other than the circuit board 5, and the fourth component can also be any component other than the shielding ring 8. The four components can be freely allocated in a non-repetitive manner, which has high flexibility. Their positions on the assembly fixture can be adjusted according to the actual situation. Correspondingly, the specific structures of the first positioning part 3011, the second positioning part 10011, and the third positioning part 603 are also adapted and adjusted according to the change of components.

[0052] In specific settings, the positioning slot can be open at both ends, closed at both ends, or open at one end and closed at the other end. This embodiment does not impose too many restrictions on this.

[0053] In a further improvement of this embodiment, a first positioning hook 2 is provided on one side of the first insert 301 for pressing the component onto the positioning recess. The hook handle of the first positioning hook 2 passes through the first side of the frame 3 in a clearance fit and extends to the outside of the frame 3. A first end cap 202 is provided on the end of the hook handle of the first positioning hook 2. A first compression spring 201 abuts between the first end cap 202 and the frame 3. The first compression spring 201 is sleeved on the hook handle of the first positioning hook 2.

[0054] Combination Figure 1 , Figure 3 and Figure 6 As shown, the first positioning hook 2 allows the first side of the frame 3 to not only press the first component (specifically, the electrode plate 4) into the positioning recess via the hook end of the first positioning hook 2, but also to press the fourth component (specifically, the shielding ring 8) into the positioning recess via the hook end of the first positioning hook 2, thus achieving a positioning effect for both types of components. In a specific implementation, after the third component (specifically, the circuit board 5) is installed in the positioning slot and before it abuts against the first component, the fourth component is fitted onto the side of the third component adjacent to the first positioning part 3011. After the third component is welded to the first component, the fourth component is moved until it abuts against the positioning recess. At this time, the first component is hidden inside the fourth component. Then, the hook end of the first positioning hook 2 presses the fourth component onto the positioning recess to achieve the positioning purpose. Finally, the weld points of the fourth component and the third component are welded to complete the assembly of the finished product.

[0055] In actual use, when the first component is not installed on the first insert 301, the hook handle of the first positioning hook 2 slides out of the frame 3, and its hook end is misaligned with the first insert 301 by rotating the angle. At this time, the first compression spring 201 is in a free state and can move along the axial direction of the hook handle of the first positioning hook 2.

[0056] The shielding ring 8 is provided with contacts that extend toward the inside of the shielding ring 8 and are electrically connected to the circuit board 5.

[0057] In another improvement of this embodiment, a second positioning hook 7 is provided on one side of the second insert 1001 for pressing the component into the positioning hole. The hook handle of the second positioning hook 7 passes through the first slider 10 in a clearance fit and extends to the second side between the first slider 10 and the frame 3. A second end cap 702 is provided at the end of the hook handle of the second positioning hook 7. A second compression spring 701 abuts between the second end cap 702 and the first slider 10. The second compression spring 701 is sleeved on the hook handle of the second positioning hook 7.

[0058] Similarly, the second positioning hook 7 is provided so that the first slider 10 can press the second component into the positioning hole through the hook end of the second positioning hook 7 to achieve the positioning purpose and prevent it from loosening.

[0059] In the specific configuration, the hook handle of the first positioning hook 2 and the first side of the frame 3, and the hook handle of the second positioning hook 7 and the first slider 10 are all clearance fit, that is, the hook handle of the first positioning hook 2 and the first side of the frame 3 are in sliding and rotational fit, and the hook handle of the second positioning hook 7 and the first slider 10 are in sliding and rotational fit.

[0060] In actual use, when the second component is not installed on the second insert 1001, the hook handle of the second positioning hook 7 slides out from the first slider 10 to the second side of the frame 3, and its hook end is misaligned with the second insert 1001 by rotation. At this time, the second compression spring 701 is in a free state and can move along the axial direction of the hook handle of the second positioning hook 7.

[0061] In another preferred embodiment, a cover plate 601 is provided on one side of the positioning slot for pressing the component onto the second slider 6, and the cover plate 601 is detachably connected to the second slider 6.

[0062] The cover plate 601 is designed so that the third component is pressed against the second slider 6 by the cover plate 601. After the assembly fixture is flipped, the third component will not fall off the third positioning, thus meeting the assembly requirement of flipping the assembly fixture to weld from the back of the component.

[0063] like Figure 6As shown, the cover plate 601 and the second slider 6 are connected by a detachable magnetic attraction. In the specific configuration, permanent magnets 15 are embedded on the adjacent sides of both the cover plate 601 and the second slider 6. The two permanent magnets 15 are opposite in polarity and attract each other. In addition, the cover plate 601 and the second slider 6 can also be detachably connected by means of buckles, bolts, etc. This embodiment does not impose too many restrictions on this.

[0064] When both ends of the positioning slot are open, a clearance groove may or may not be provided on the side of the cover plate 601 adjacent to the second slider 6; when both ends of the positioning slot are closed, a clearance groove needs to be provided on the side of the cover plate 601 adjacent to the second slider 6, and the two ends of the clearance groove are open; when one end of the positioning slot is open and the other end is closed, a clearance groove needs to be provided on the side of the cover plate 601 adjacent to the second slider 6, and the end of the clearance groove opposite the closed end of the positioning slot is open.

[0065] Combination Figure 2 and Figure 3 As shown, as a further improvement of this embodiment, it also includes a base plate 1, on which a first positioning block 101 and two second positioning blocks 102 are provided. The frame 3 is engaged between the two second positioning blocks 102, and the outer side of the first side of the frame 3 abuts against the first positioning block 101.

[0066] The arrangement of the first positioning block 101 and the second positioning block 102 allows the third and fourth sides of the frame 3 to abut against the second positioning block 102, thus locking the assembly fixture between the two second positioning blocks 102 and positioning it in the width direction. Simultaneously, the outer side of the first side of the frame 3 abuts against the first positioning block 101, preventing interference with the locking assembly and also positioning the assembly fixture in the length direction. With the assembly fixture positioned in both the length and width directions, it is equivalent to coordinate positioning on a plane. Especially after the assembly fixture is flipped, this ensures the accuracy of its relative position to other equipment such as welding machines, facilitating high-precision machining.

[0067] Preferably, the first positioning block 101 and the second positioning block 102 are integrally formed. In addition, the first positioning block 101 and the second positioning block 102 can be connected to each other or spaced apart from each other. This embodiment does not impose too many restrictions on this.

[0068] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
