[0124] The limiting component of the embodiment of the present invention will be further described below with reference to the accompanying drawings.

[0125] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings. It is worth mentioning that the directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are for illustration and not for limitation of the present invention. In addition, in the following embodiments, the same or similar components will be labeled with the same or similar numbers.

[0126] like Figures 1 to 4 As shown, in one of the specific embodiments of the first aspect of the present invention, the limiting component includes a fixing seat 1, a fixing member 2, a fixing member reciprocating movement generating member 3 and an elastic component 4. The fixing seat 1 can be fixed to the fixing through hole 81 of the first object 8 (such as a plate or an object of other structures) by means of the buckling unit 12a at the bottom of the fixing seat 1. The fixing seat 1 can be in a cap shape and have a through hole 11 on its top; the fixing member 2 has a stop unit 21, a connecting unit 22 and a fixing unit 23 connected in sequence, and the fixing member 2 gradually shrinks from the stop unit 21 to the connecting unit 22. The fixing unit 23 is used to pass through the fixing through hole 81 of the first object 8 and be fixed to the fixing hole 91 (such as a through hole or a concave hole) of the second object 9 (such as a plate or an object of other structures). The fixing unit 23 can be a column and its cross-sectional area is slightly larger than the fixing hole 91, so that the fixing unit 23 can enter the fixing hole 91, and then the fixing unit 23 can be fixed to the fixing hole 91; the fixing member reciprocating movement generating member 3 is movably arranged on the fixing seat 1 and can be relative to the fixing The fixed seat 1 moves laterally, the connecting unit 22 penetrates the fixed part reciprocating motion generating member 3 and the through hole 11 of the fixed seat 1 and is movably arranged on the fixed part reciprocating motion generating member 3 and the fixed seat 1, the stop unit 21 stops on the fixed part reciprocating motion generating member 3, the elastic component 4 can be a telescopic spring or other forms of springs or elastomers and can be sleeved on the connecting unit 22, one end of the elastic component 4 abuts against the top inside the fixed seat 1, and the other end abuts against the fixing unit 23 of the fixing member 2. When the fixing member 2 is assembled with the fixed seat 1 and the fixed part reciprocating motion generating member 3, the connecting unit 22 can be first penetrated through the fixed seat 1 and the fixed part reciprocating motion generating member 3, and then the stop unit 21 or the fixing unit 23 can be assembled to the connecting unit 22, or the connecting unit 22 can be processed to form the stop unit 21 or the fixing unit 23. When the fixed part reciprocating motion generating member 3 moves to the left (such as Figure 2 or Figure 3As shown in the figure), the fixing member reciprocating movement generating member 3 will push the stop unit 21 (the fixing member 2) upward and make the fixing seat 1 and the fixing unit 23 press the elastic component 4. With the help of the outward pre-force generated by the elastic component 4 after pressurization, the fixing member 2 can be firmly pressed against the fixing member reciprocating movement generating member 3 without shaking, so that the fixing unit 23 can be easily aligned with the fixing hole 91 of the second object 9; when the fixing member reciprocating movement generating member 3 moves to the right (as shown in the figure), the fixing member reciprocating movement generating member 3 will push the stop unit 21 (the fixing member 2) upward and make the fixing seat 1 and the fixing unit 23 press the elastic component 4. Figure 4 As shown), the elastic component 4 releases the pre-force to allow the stop unit 21 to retract into the fixing member reciprocating movement generating member 3 and move the fixing member 2 downward, so that the fixing unit 23 can enter the fixing hole 91 of the second object 9, thereby achieving the effect of fixing the first object 8 and the second object 9.

[0127] In summary, the limiting assembly of the first aspect of the present invention can make the fixing unit 23 reciprocate and prevent the fixing member 2 from shaking easily by means of the fixing member reciprocating motion generating member 3 and the elastic member 4; in addition, the limiting assembly of the first aspect of the present invention can make the fixing unit 23 reciprocate outside and inside the fixing seat 1 (such as Figure 2 and Figure 4 As shown), or reciprocating outside the fixed seat 1 (as shown Figure 3 and Figure 4 shown).

[0133] In addition, if Fig.11As shown, the fixing seat 1 of the limiting assembly can also be formed integrally with the first object 8 .

[0134] like Figure 12 to Figure 14 As shown, in addition to the above-mentioned column, the fixing unit of the above-mentioned limiting assembly can also be a buckle body 24 (such as Fig.12 As shown), the snap body 25 (as Fig.13 as shown) or thread 26 (as shown Fig.14 as shown) to be fixed to the second object 9.

[0135] like Figures 15 to 18 As shown, in one of the specific embodiments of the second aspect of the present invention, the limiting component includes a fixed seat 1, a fixed member 2, a fixed member reciprocating movement generating member 3 and an elastic component 4, and the fixed seat 1 and the fixed member reciprocating movement generating member 3 are respectively provided with structures that can cooperate to prevent relative rotation.

[0136] In detail, the fixing seat 1 has a head 1a and an assembly part 1b, wherein the head 1a can be located at the top of the fixing seat 1, and the assembly part 1b can be located at the bottom of the fixing seat 1. The interior of the fixing seat 1 is hollow, and the head 1a has a through hole 11 connected to the interior of the fixing seat 1, and a groove 1e is formed in the assembly part 1b. The assembly part 1b can be used to fix to a first object 8 (such as a plate or an object of other structures), for example, fixed to a fixing through hole 81 of the first object 8. The fixing seat 1 also has a first anti-rotation part 13, which is located between the head 1a and the assembly part 1b, and is used to limit the displacement direction of the fixing member reciprocating movement generating member 3 relative to the fixing seat 1 and prevent the two from rotating relative to each other. For example, but not limited to, in this specific embodiment, the first anti-rotation portion 13 can be formed on the outer circumferential surface 1c of the fixing seat 1, and the first anti-rotation portion 13 can be, for example, to partially form a plane on the outer circumferential surface 1c of the fixing seat 1, that is, to form a non-circular radial cross section of the outer circumferential surface 1c of the fixing seat 1 at the first anti-rotation portion 13, and a shoulder 1d can be formed at the junction of the first anti-rotation portion 13 and the head 1a. Preferably, the first anti-rotation portion 13 can form planes at two radially opposite positions, for example, to form planes at two radially opposite positions on the outer circumferential surface 1c of the fixing seat 1, so that the first anti-rotation portion 13 can form a symmetrical shape.

[0137] The fixing member 2 has a stop unit 21, a connecting unit 22 and a fixing unit 23 connected in sequence, the fixing member 2 passes through the fixing seat 1, and the stop unit 21 is located above the head 1a of the fixing seat 1, and the fixing unit 23 can be located in the receiving groove 1e of the assembly portion 1b, and is used to be fixed to the second object 9 or other objects, wherein the second object 9 can be, for example, a plate or an object of other structure, and can be, for example, fixed to the fixing hole 91 (such as a through hole or a recessed hole) of the second object 9.

[0138] More specifically, in this specific embodiment, the fixing member 2 can be formed by the connecting unit 22 passing through the through hole 11 of the head 1a of the fixing seat 1, and the stop unit 21 is located at the top of the connecting unit 22 and outside the fixing seat 1. The stop unit 21 can be formed into an inverted cone shape that gradually shrinks toward the connecting unit 22 and has an inwardly inclined stop surface 211. The fixing unit 23 is located at the bottom of the connecting unit 22, and the shape of the fixing unit 23 can be different according to the assembly requirements; for example, it can be Figure 2 The column shown, or another Fig.12 The buckle body 24 shown, Fig.13 The snap body 25 or Fig.14 In addition, the elastic component 4 is located in the fixing seat 1 and sleeved on the connecting unit 22, and the two ends of the elastic component 4 are respectively abutted against the head 1a of the fixing seat 1 and the fixing unit 23; the elastic component 4 can be, for example, a compression spring or an elastic body.

[0139] The fixed part reciprocating movement generating member 3 has a base plate 3a and a second anti-rotation portion 3b, the second anti-rotation portion 3b is connected to the base plate 3a, the base plate 3a is located above the head portion 1a of the fixed seat 1, and the second anti-rotation portion 3b corresponds to the first anti-rotation portion 13. In this way, the fixed part reciprocating movement generating member 3 can be displaced laterally relative to the fixed seat 1, and the second anti-rotation portion 3b is limited by the first anti-rotation portion 13, so that the fixed part reciprocating movement generating member 3 can only be displaced relative to the fixed seat 1 but cannot be relatively rotated.

[0140] The limiting direction of the first anti-rotation part 13 and the second anti-rotation part 3b is used to limit the movement direction of the fixed part reciprocating movement generating part 3. The first anti-rotation part 13 or the second anti-rotation part 3b can form a plane, or the first anti-rotation part 13 or the second anti-rotation part 3b can form a concave part or a convex part. The second anti-rotation part 3b can have an extended structure or a hook part 33 connected to the structure, or the head 1a of the fixed seat 1 can be accommodated between the hook part 33 and the base plate 3a, or the hook part 33 corresponds to the first anti-rotation part 13 and extends into the shoulder 1d of the fixed seat 1. In this specific embodiment, the second anti-rotation portion 3b may have a structure (such as a plate 32) extending downward from the base plate 3a, and a hook portion 33 extending inward from the plate 32; accordingly, the head portion 1a of the fixing seat 1 may be accommodated between the hook portion 33 and the base plate 3a, and the hook portion 33 may correspond to the first anti-rotation portion 13 and extend under the shoulder portion 1d, so that the fixing member reciprocating movement generating member 3 may be displaced along the first anti-rotation portion 13, but when rotating relative to the fixing seat 1, it will not be able to rotate because the hook portion 33 abuts against the first anti-rotation portion 13. In order to improve the smoothness of the aforementioned relative movement, the second anti-rotation portion 3b of this specific embodiment preferably has two opposite plates 32 and two facing hook portions 33, so as to correspond to the aforementioned symmetrical first anti-rotation portion 13, and provide a better guiding displacement and anti-rotation effect.

[0141] On the other hand, the fixed member reciprocating movement generating member 3 may have a retracting and pushing unit 31, or the connecting unit 22 may be arranged through the retracting and pushing unit 31 and the through hole 11 of the fixed seat 1, or when the fixed member reciprocating movement generating member 3 is displaced relative to the fixed seat 1, the retracting and pushing unit 31 may drive the fixed member 2 to reciprocate to compress or release the elastic component 4. In this specific embodiment, the fixed member reciprocating movement generating member 3 may have a retracting and pushing unit 31 arranged on the substrate 3a, and when the fixed member reciprocating movement generating member 3 is assembled to the fixed seat 1, a part of the retracting and pushing unit 31 may be positioned relative to the through hole 11. In this way, the connecting unit 22 of the fixed member 2 may pass through the retracting and pushing unit 31 and the through hole 11, and when the fixed member reciprocating movement generating member 3 is displaced relative to the fixed seat 1, the retracting and pushing unit 31 may also drive the fixed member 2 to reciprocate to compress or release the elastic component 4.

[0142] For example, the retracting and extrapolating unit 31 of this specific embodiment has a slot 314, and the slot 314 can penetrate the base plate 3a, and the slot 314 can have a connected retracting area 311 and an extrapolating area 313. The slot width of the slot 314 in the extrapolating area 313 can be greater than the width of the connecting unit 22 and less than the width of the stop unit 21, so that the stop unit 21 can protrude from the slot 314 when corresponding to the extrapolating area 313 (e.g., Fig.17 The slot 314 may be provided with an outwardly inclined stop surface 312 in the retracted area 311 to form an inverted cone-shaped receiving groove, so that the stop unit 21 may be at least partially immersed in the slot 314 when corresponding to the retracted area 311 (as shown); Fig.18 shown).

[0143] It is worth mentioning that, in order to facilitate assembly, at least one of the stop unit 21 and the fixing unit 23 of the fixing member 2 is preferably combined with the connecting unit 22 after the connecting unit 22 passes through the through hole 11 and the slot 314, or the connecting unit 22 is processed to form the stop unit 21 or the fixing unit 23; this is understandable to those with ordinary knowledge in the field and is not the focus of the present invention, so the figures are all illustrated in an integrated form.

[0144] like Fig.17 As shown, according to the aforementioned structure, when using the limiting component of the second embodiment of the present invention, the fixing seat 1 can be first connected to the fixing through hole 81 of the first object 8 by its assembly part 1b, and the fixing part reciprocating movement generating member 3 is aligned with the fixing part 2 by the push-out area 313 of the retraction and push-out unit 31; at this time, the base plate 3a of the fixing part reciprocating movement generating member 3 will push the stop unit 21 of the fixing part 2 upward, so that the upwardly moved fixing unit 23 will pressurize the elastic component 4, so that the fixing part 2 can be firmly abutted against the base plate 3a of the fixing part reciprocating movement generating member 3 without shaking, so that the fixing unit 23 can be easily and accurately aligned above the fixing hole 91 of the second object 9.

[0145] Continue as Fig.18 As shown, the reciprocating movement of the fixing member generates a lateral displacement of the member 3, so that the retraction and outward thrust unit 31 is changed to align with the fixing member 2 via the retraction area 311; at this time, since the stop unit 21 of the fixing member 2 can align with the outwardly inclined stop surface 312 to be immersed in the slot 314, the elastic component 4 can release the preload to drive the entire fixing member 2 to move downward, so that the fixing unit 23 can penetrate into the fixing hole 91 of the second object 9, thereby achieving the effect of fixing the first object 8 and the second object 9.

[0146] Please refer to Fig.15As shown, in a specific embodiment, the assembly portion 1b of the fixing seat 1 and the fixing through hole 81 of the first object 8 can form a matching and non-circular shape, or be used to limit the direction of the fixing seat 1 in the first object 8, so as to limit or conform to the limiting direction of the first anti-rotation portion 13 and the second anti-rotation portion 3b, so that the assembly portion 1b of the fixing seat 1 and the fixing through hole 81 of the first object 8 can also produce an anti-rotation effect after being combined, which can help improve the combination stability of the fixing seat 1 and the first object 8, and improve the stability of the subsequent operation when pushing the fixing member reciprocating movement generating member 3. In addition, in order to improve the convenience of operation when pushing the fixing member reciprocating movement generating member 3, the base plate 3a of the fixing member reciprocating movement generating member 3 can also be provided with a protruding lifting portion 34 at one of the end edges in the pushing direction, so as to facilitate the user's finger pinching and force application.

[0147] Please refer to Fig.19 and Fig. 20 As shown, in another specific embodiment of the second aspect of the present invention, an auxiliary limiting portion 14 may be further provided between the first anti-rotation portion 13 of the fixing seat 1 and the assembly portion 1b, so that the hook portion 33 of the reciprocating movement generating member 3 of the fixing member can extend between the shoulder 1d and the auxiliary limiting portion 14, and can more stably move back and forth along the first anti-rotation portion 13.

[0148] Please refer to Fig.21 As shown, in another specific embodiment of the second aspect of the present invention, the slot 314 of the retracting and pushing unit 31 of the fixed reciprocating motion generating member 3 may have a retracting area 311 located between two pushing areas 313; in this way, the user can achieve the aforementioned operation of fixing the first object 8 and the second object 9 by pushing the fixed reciprocating motion generating member 3 to the left or right, which has the effect of improving the convenience of operation. Furthermore, the base plate 3a of the fixed reciprocating motion generating member 3 may also be provided with a convex lifting portion 34 on both sides of one of the end edges in the pushing direction, so as to be pinched by two fingers of the user, which has the effect of further improving the comfort and smoothness of operation.

[0149] Please refer to Fig. 22As shown, in another specific embodiment of the second aspect of the present invention, the fixing member 2 can be prevented from rotating relative to the fixing seat 1; that is, the fixing seat 1 can be provided with a third anti-rotation portion 15, and the fixing unit 23 can be provided with a fourth anti-rotation portion 27 corresponding to the third anti-rotation portion 15, so as to achieve the effect of restricting the fixing member 2 from rotating. For example, the fixing seat 1 of this specific embodiment can form a non-circular shape in the radial cross section of the groove 1e of the assembly portion 1b to form the third anti-rotation portion 15; and the fixing unit 23 can form a shape matching the groove 1e in the radial cross section of the fourth anti-rotation portion 27, so that when the fixing unit 23 is located in the groove 1e of the assembly portion 1b, the fourth anti-rotation portion 27 and the third anti-rotation portion 15 can restrict each other and cannot rotate relative to each other, thereby achieving the effect of preventing the fixing member 2 from rotating relative to the fixing seat 1.

[0150] On the other hand, please refer to Fig.23 As shown, in this specific embodiment, the fixing unit 23 of the fixing member 2 may also have a guide surface 231, and the guide surface 231 may be located at the bottom end of the fixing unit 23, for example, the bottom end of the fixing unit 23 forms a convex hemispherical surface, or the guide surface 231 may also be an arc surface, a circular surface, a curved surface, a stepped surface, or an inclined surface. Figure 23 to Figure 25 As shown, after the fixing seat 1 has been connected to the fixing through hole 81 of the first object 8 by its assembly part 1b, when the bottom end of the fixing unit 23 of the fixing member 2 protrudes outside the assembly part 1b, it can contact the end edge of the second object 9 (such as Fig.23 When the guide surface 231 is guided, the second object 9 pushes against the guide surface 231, so that the fixing member 2 moves upward and the elastic component 4 (indicated at Fig.16 ) is pressed, and the bottom end of the fixing unit 23 can abut against the second object 9 and translate relative to the second object 9 (such as Fig.24 When the bottom end of the fixing unit 23 is aligned with the fixing hole 91 of the second object 9, the elastic component 4 can release the pressure to drive the entire fixing member 2 to move downward, so that the fixing unit 23 can penetrate into the fixing hole 91 of the second object 9, thereby achieving the effect of combining and fixing the first object 8 and the second object 9 (as shown in FIG. Fig.25 shown).

[0151] In addition, the fixing unit 23 may have a limiting portion 232 for limiting the second object 9, or the fixing unit 23 may have the guiding surface 231 on one side and the limiting portion 232 on the other side, so as to guide the fixing unit 23 into the second object 9 by the guiding surface 231 and limit the separation by the limiting portion 232. In one specific embodiment of the second aspect of the present invention, the fixing unit 23 of the fixing member 2 may form the guiding surface 231 adjacent to the bottom end, and the limiting portion 232 may be formed by a relatively straight portion around the fixing unit 23. Accordingly, the bottom end of the fixing unit 23 of the fixing member 2 can be guided by the guide surface 231, so that the fixing member 2 that moves in translation can be pushed by the end edge of the second object 9 and retract upward, and after the bottom end of the fixing unit 23 is aligned and inserted into the fixing hole 91 of the second object 9, the fixing member 2 is restricted by the limiting portion 232 from moving back and retracting the fixing member 2, which has the effect of further improving the stability of the combination of the first object 8 and the second object 9. In addition, the fixing member 2 and the fixing seat 1 can be used to limit the anti-rotation, or the fixing member 2 and the fixing member reciprocating movement generating member 3 can be used to limit the anti-rotation, so as to limit the direction of the guide surface 231 or the direction of the limiting portion 232.

[0152] Please refer to Fig.26 As shown, in one of the specific embodiments of the second aspect of the present invention, the fixing member 2 can be prevented from rotating relative to the fixing member reciprocating movement generating member 3; that is, the fixing member reciprocating movement generating member 3 can be provided with a fifth anti-rotation portion 35, and the fourth anti-rotation portion 27 of the fixing member 2 corresponds to the fifth anti-rotation portion 35, so as to achieve the effect of restricting the fixing member 2 from rotating. For example, the reciprocating movement generating member 3 of the fixed member can form an inverted cone-shaped groove with a non-circular shape for the outwardly inclined stop surface 312 of the retraction zone 311 of the slot 314 to form the fifth anti-rotation portion 35; and the stop unit 21 of the fixed member 2 is formed in a state that roughly matches the outwardly inclined stop surface 312 of the retraction zone 311 to form the fourth anti-rotation portion 27, so that when the stop unit 21 corresponds to the retraction zone 311, the fourth anti-rotation portion 27 and the fifth anti-rotation portion 35 can restrict each other and cannot rotate relative to each other, thereby achieving the effect of preventing the fixed member 2 from rotating relative to the reciprocating movement generating member 3 of the fixed member.

[0153] Please refer to Fig. 27As shown, in one of the specific embodiments of the second aspect of the present invention, there may be another laterally arranged elastic reset member 5, one end of the elastic reset member 5 abuts against the fixed member reciprocating movement generating member 3, and the other end abuts against the fixed seat 1, so that the fixed member 2 can be located in a lowered position or in an ascended position. In detail, the base plate 3a of the fixed member reciprocating movement generating member 3 may also be provided with an extension portion 36 extending downward at one end in the pushing direction, one end of the elastic reset member 5 abuts against the extension portion 36, or the extension portion 36 may be provided with a groove 361, the opening of the groove 361 faces the fixed seat 1, and the groove 361 can be used to accommodate one end of the elastic reset member 5, so as to enhance the stability of the elastic reset member 5. In this specific embodiment, the extension portion 36 of the fixed member reciprocating movement generating member 3 is arranged at a position closer to the push-out zone 313 and farther away from the retraction zone 311. Accordingly, when the limiting component is in an unstressed state, the extension portion 36 of the reciprocating movement generating member 3 of the fixing member can be affected by the elastic force of the elastic reset member 5 and maintain a predetermined distance from the fixing seat 1; at this time, the stop unit 21 of the fixing member 2 can correspond to the retraction area 311 and sink into the slot 314, and the fixing unit 23 of the fixing member 2 can be in an extended state.

[0154] When locking to the second object 9, the user can operate and push the fixing member reciprocating movement generating member 3 so that the extension portion 36 is pushed in the direction close to the fixing seat 1 to compress the elastic return member 5, and the stop unit 21 of the fixing member 2 can be guided and lifted up by the push-out area 313 of the slot hole 314, so that the fixing unit 23 of the fixing member 2 shrinks upward and compresses the elastic component 4; after the fixing unit 23 is aligned to the top of the fixing hole 91 of the second object 9, the user only needs to release the fixing member reciprocating movement generating member 3, and the elastic return ability of the elastic return member 5 can be used to move the extension portion 36 of the fixing member reciprocating movement generating member 3 away from the fixing seat 1, so that the stop unit 21 of the fixing member 2 corresponds to the retraction area 311 and sinks into the slot hole 314, so that the fixing unit 23 of the fixing member 2 extends out to penetrate into the fixing hole 91 of the second object 9, thereby having the effect of improving the convenience of operation during locking.

[0155] Please refer to Fig.28As shown, in another specific embodiment, the extension portion 36 of the fixing member reciprocating movement generating member 3 is arranged at a position closer to the retracting area 311 and farther from the outward pushing area 313. Accordingly, when the limiting component is in a state without force, the extension portion 36 of the fixing member reciprocating movement generating member 3 can be subjected to the elastic force of the elastic reset member 5 to maintain a predetermined distance from the fixing seat 1; at this time, the stop unit 21 of the fixing member 2 can correspond to the outward pushing area 313, so that the fixing member 2 is in an upward lifting state and compresses the elastic component 4.

[0156] When locking to the second object 9, the user can operate and push the fixing member reciprocating movement generating member 3 to push its extension 36 in the direction close to the fixing seat 1 to compress the elastic reset member 5, and the stop unit 21 of the fixing member 2 can correspond to the retracted area 311 and sink into the slot 314, and the elastic component 4 can be elastically reset to push the fixing unit 23 of the fixing member 2 to extend and penetrate into the fixing hole 91 of the second object 9. When unlocking the state, the user only needs to gently push the fixing member reciprocating movement generating member 3 to slightly move the extension 36 away from the fixing seat 1, and the elastic reset ability of the elastic reset member 5 can be used to drive the entire fixing member reciprocating movement generating member 3 to move, so that the extension 36 moves away from the fixing seat 1, so that the stop unit 21 of the fixing member 2 corresponds to the push-out area 313 of the slot 314, so that the fixing member 2 is lifted up to separate from the second object 9, so it has the effect of improving the convenience of operation when unlocking.

[0157] The first object 8 or the second object 9 may be a server, a storage, a motherboard, a PCB board, a track, a cabinet, a data center, an IC, a chip, a radiator, a fan, a casing, a chassis, a metal object or a plastic object.

[0158] In summary, the limiting assembly of the first aspect of the present invention can make the fixing unit 23 reciprocate and prevent the fixing member 2 from shaking easily by means of the fixing member reciprocating motion generating member 3 and the elastic member 4; in addition, the limiting assembly of the first aspect of the present invention can make the fixing unit 23 reciprocate outside and inside the fixing seat 1 (such as Figure 2 and Figure 4 As shown), or reciprocating outside the fixed seat 1 (as shown Figure 3 and Figure 4In addition, the limiting component of the second aspect of the present invention can be provided with a first anti-rotation portion 13 and a second anti-rotation portion 3b that can cooperate with each other, so that the fixing member reciprocating movement generating member 3 can only be displaced relative to the fixing seat 1 but cannot be relatively rotated (the so-called rotation here refers to a relatively large relative rotation, but does not exclude a slight rotation caused by structural adaptation or looseness), thereby achieving the effect of further improving the operational stability, convenience and efficiency during assembly.
