Description

Technical Field

[0001] This utility model relates to bicycle saddles, and in particular to a bicycle saddle with a detachable base and a top seat. It has a special interlocking structure that effectively improves the convenience of assembly and disassembly, and provides saddle assembly stability. Background Technology

[0002] Traditional bicycle saddles typically consist of a base, a filling layer, and a surface cover. The filling layer and the surface cover are combined to form a single saddle, which is then fixed to the base using methods such as gluing, riveting, or screwing. Because this structure permanently fixes the saddle to the base, when the saddle is damaged, or when the user wants to choose a saddle with different firmness, material, or shape according to personal needs, the entire saddle usually needs to be replaced, resulting in resource waste and high replacement costs.

[0003] To overcome the aforementioned problems, the industry has developed various bicycle saddles with detachable bases and saddle bodies. For example, Chinese patents CN 212667564U and CN 210310672U, and US patent US 9,957,009 disclose various bicycle saddles with detachable structures. While such technologies do provide the feasibility of saddle replacement, existing detachable structures still have several drawbacks. For instance, some structures use screws or clamps as fixing elements, requiring tools for assembly and disassembly, making operation inconvenient. Furthermore, some structural designs are quite complex, increasing manufacturing costs and making it difficult to ensure the stability of the assembled structure. In other words, existing detachable bicycle saddles still have room for improvement in terms of ease of assembly and disassembly, ensuring assembly stability, and simplifying the structure to reduce costs. Utility Model Content

[0004] To address the aforementioned issues, this application provides a bicycle seat cushion with a simple structure that is easy to assemble and disassemble. Its installation and disassembly process is quick, requires no special tools, and ensures assembly stability.

[0005] According to a specific embodiment of the present invention, a bicycle seat cushion is provided, comprising:

[0006] A base having a front end, a rear end, and a body connecting the front end and the rear end, the base having a longitudinally extending mounting groove penetrating its top and bottom surfaces; and

[0007] The top seat has a front end, a rear end, and a body connecting the front end and the rear end of the top seat. The top seat has a locking portion protruding downward from its bottom surface. The locking portion can slide longitudinally along the mounting groove between a non-locking position that can pass into and out of the mounting groove and a locking position that can be locked and fixed in the mounting groove, so that the top seat can be detachably fixed to the base.

[0008] Through the aforementioned structural features, namely the interaction between the longitudinally extending mounting groove of the base and the downwardly protruding inserting part of the top seat, the top seat can be fixed to the base by inserting the inserting part into the mounting groove and sliding it longitudinally relative to the base along the mounting groove. Conversely, the top seat can be removed from the base by sliding the inserting part in the opposite direction relative to the base along the mounting groove. The entire assembly and disassembly process does not require tools, making the operation quite easy and convenient, and the structure is very simple. Furthermore, during assembly, the inserting part needs to slide a certain length longitudinally relative to the base along the mounting groove to be fixed in place, providing considerable assembly stability, thereby achieving the aforementioned objectives of this utility model.

[0009] In a preferred embodiment, the mounting slot includes a front slot and a rear slot that communicates with the front slot and is closer to the rear end of the base than the front slot; the non-embedded position is located in the front slot, while the embedded position is located in the rear slot.

[0010] With this configuration, the user can hold the rear end of the top mount and slide it onto the base from front to back to complete the assembly, which is quite convenient.

[0011] In a preferred embodiment, the width of the front slot of the mounting groove is greater than the width of the rear slot of the mounting groove.

[0012] The size configuration of the front and rear slots allows the locking part of the top seat to easily pass through the wider front slot (non-locking position) and to be securely locked when sliding to the narrower rear slot (locking position).

[0013] In a preferred embodiment, the width of the front slot of the mounting groove gradually decreases from the front end of the front slot towards the rear slot.

[0014] This allows the inserting part of the top seat to easily enter and exit the front end of the front slot (non-inserting position), and when sliding backward, it can be gradually guided or even gradually squeezed, so as to smoothly slide into the rear slot.

[0015] In a preferred embodiment, the mounting groove further includes a transition area connecting the front slot and the rear slot; the width of the front slot of the mounting groove gradually decreases from the front end of the front slot towards the transition area, and the width of the rear slot of the mounting groove maintains a constant width for at least a section from the transition area towards the rear end of the rear slot.

[0016] With this size configuration, the locking part of the top seat can easily pass through the wider front slot (non-locking position), and when sliding backward, it can be gradually guided to smoothly enter the narrower rear slot (locking position) and be firmly locked and fixed by the squeeze of the hole wall.

[0017] In a preferred embodiment, the locking part includes two longitudinally arranged and spaced-apart fasteners, each fastener having a neck that can slide longitudinally in the front slot and the rear slot, and a head connected to the neck; when the locking part is in the non-locking position, the head of each fastener can pass into and out of the mounting groove; when the locking part is in the locking position, the head of each fastener abuts against the bottom surface of the base, and the neck of each fastener abuts against the wall of the rear slot.

[0018] With this size configuration, when the user holds the top seat and slides the insert part of the top seat into the mounting slot from front to back into the insert position, the two buckles enter the rear slot hole through the transition area, so that the user can clearly feel that the top seat has slid into the position.

[0019] In a preferred embodiment, the insert portion includes a neck that can slide longitudinally in the front slot and the rear slot, and a head connected to the neck; when the insert portion is in the non-inserted position, the head can pass into and out of the mounting groove; when the insert portion is in the inserted position, the head abuts against the bottom surface of the base, and the neck abuts against the wall of the rear slot.

[0020] Thus, in the non-embedded position, the top seat's inserting part can be inserted downwards into or disengaged upwards from the front slot, while in the inserting position, the top seat can be securely inserted and fixed to the base, and cannot be disengaged upwards from the base.

[0021] In a preferred embodiment, the mounting groove includes a front slot and a rear slot separated from the front slot. The width of the front slot gradually decreases from the front end to the rear end, and the width of the rear slot gradually decreases from the front end to the rear end. The locking part includes two longitudinally arranged and spaced-apart fasteners. Each fastener has a neck and a head connected to the neck. When the locking part is in the non-locking position, the head of each fastener can pass through the front slot and the rear slot respectively. When the locking part is in the locking position, the head of each fastener abuts against the bottom surface of the base, and the neck of each fastener abuts against the wall of the front slot and the rear slot respectively.

[0022] This multi-slot and multi-buckle structure, combined with the longitudinal sliding action of the top mount relative to the base, ensures that the top mount is securely attached to the base or smoothly detached from the base.

[0023] In a preferred embodiment, the mounting groove has a front end and a rear end, the width of the mounting groove gradually narrows from the front end to the rear end, and at least one of the two opposing walls of the mounting groove is provided with teeth; the locking part includes a neck and a head connected to the neck; when the locking part is in the non-locking position, the head can pass into and out of the mounting groove, and when the locking part is in the locking position, the head abuts against the bottom surface of the base, and the neck abuts against the wall of the mounting groove.

[0024] Therefore, when the top mount slides longitudinally between the non-clamped and clamped positions relative to the base, the user can feel obvious vibration feedback at different stages to ensure that the user can accurately slide the top mount to the final fixed position.

[0025] In a preferred embodiment, at least one of the two opposing walls of the mounting groove is provided with teeth, the teeth having a plurality of teeth and a plurality of positioning recesses, each of the positioning recesses being located between two adjacent teeth; at least one of the plurality of positioning recesses allows the inserting part to pass into and out of the mounting groove, while at least one of the plurality of positioning recesses can be used to lock and fix the inserting part.

[0026] In this way, when the locking part of the top seat slides longitudinally relative to the mounting groove of the base, the locking part can abut against the teeth and stop in a specific positioning recess. In this way, the user can feel obvious vibration feedback and ensure that the top seat is slid to a specific fixed position.

[0027] In a preferred embodiment, the front end of the top seat has a locking hole on its bottom surface, the locking hole having an opening that opens toward the rear end of the top seat; when the locking part is in the locking position, the front end of the base passes through the opening and is locked in the locking hole.

[0028] In this way, the top mount can be more securely locked into the base, ensuring that it cannot detach from the base upwards.

[0029] In a preferred embodiment, the top seat has a left locking groove and a right locking groove located on its bottom surface and distributed along its left and right edges respectively, and the base has a left edge and a right edge; when the locking part is in the locking position, the left edge of the base is locked in the left locking groove, and the right edge of the base is locked in the right locking groove.

[0030] This not only enhances the bonding strength between the top and the base, but also provides additional protection against lateral sliding and damage.

[0031] In a preferred embodiment, the rear end of the top seat has an insert extending downward from its rear end; when the insert is in the insert position, the insert of the top seat hooks onto the rear end of the rear end portion of the base.

[0032] This strengthens the connection between the top mount and the base, preventing the rear end of the top mount from detaching from the rear end of the base during use and improving the overall structural stability.

Conversely, when it is stated that an element is "directly" disposed on another element, it means that no other elements are disposed between the two elements.

[0054] The terms "comprising," "including," and "having" used in this utility model are all open-ended terms, meaning "including but not limited to." In the descriptions of the various embodiments, when terms such as "first," "second," "third," and "fourth" are used to describe elements, they are only used to distinguish these elements from each other and do not limit the order or importance of these elements.

[0055] Please refer to the following: Figure 1 and Figure 2The bicycle saddle 1 provided in the first preferred embodiment of this utility model includes a base 10 and a top seat 30. The base 10 is used to fix to the bicycle seat post (not shown) and provide structural support, while the top seat 30 provides riding support for the rider. The base 10 and the top seat 30 can be easily disassembled and assembled together to form a complete bicycle saddle 1.

[0056] See also Figures 3 to 8 and Figure 10 The base 10 has a seat arch 11 for mounting on the bicycle seatpost (not shown), and a base plate 12 connected to the seat arch 11. The base plate 12 has a longitudinally extending mounting groove 13 that extends through its top surface 121 and bottom surface 122, and opposing left and right edges 15a and 15b. The mounting groove 13 is used to secure the top mount 30, while the left and right edges 15a and 15b can form a mating or covering relationship with specific parts of the top mount 30 (detailed below) to enhance the assembly stability, especially lateral stability, when assembling the top mount 30 and the base 10. In this embodiment, the seat arch 11 and the base plate 12 are integrally molded from carbon fiber reinforced resin material to ensure structural strength, integrity, and stability. The carbon fiber reinforced resin material possesses high strength, lightweight, high rigidity, and excellent corrosion resistance and fatigue life, effectively reducing overall weight, improving durability and riding performance, reducing deformation during riding, and enhancing stability and comfort. However, this invention is not limited to these limitations. For example, the base 11 can be made of metal (such as iron, aluminum alloy, stainless steel, etc.), while the base plate 12 can be made of plastic (such as engineering plastics, reinforced plastics, etc.). Metal provides good structural strength, while plastic helps reduce costs and increase design flexibility. In other words, the choice of material and structural form for the base 10 can be adjusted according to actual application needs and cost-effectiveness.

[0057] The base plate 12 has a front end 12a, a rear end 12b, and a body 12c connecting the two. In this embodiment, the front end 12a is relatively long and narrow compared to the rear end 12b; however, the base plate 12 provided by this utility model is not limited to having a narrow front end 12a and a wide rear end 12b. Furthermore, the front end 12a has an arc-shaped front end 12a1, and the left and right side edges of the front end 12a gradually extend backward and outward from the front end 12a1 and are integrally connected to the body 12c. The front end 12a provides front support and positioning for the overall bicycle seat 1 structure, and its bottom surface is fixedly connected to the front end of the seat arch 11. Secondly, the left and right side edges of the body 12c gradually extend backward, outward, and downward from the front end 12a and are integrally connected to the rear end 12b. The left and right side edges of the rear end 12b extend backward and inward from the body 12c and are connected to the arc-shaped rear end 12b1. The bottom surface of the rear end 12b is fixedly connected to the two forked ends of the seat arch 11, so that the rear end 12b can provide rear support for the overall bicycle seat 1 structure.

[0058] In this embodiment, the mounting groove 13 extends longitudinally. Here, "longitudinal" refers to the direction along the longitudinal axis formed by the front end 12a1 and the rear end 12b1. Moreover, the mounting groove 13 is mainly distributed in the body 12c and the rear end 12b. However, the present invention is not limited thereto. For example, the mounting groove 13 may extend longitudinally and be distributed in the front end 12a, body 12c and rear end 12b at the same time, or it may be distributed only in the body 12c or the rear end 12b.

[0059] Please refer to this document. Figure 8 The mounting slot 13 has a front slot 131 and a rear slot 132 that are interconnected, and a transition area 133 connecting the front slot 131 and the rear slot 132. The width W1 of the front slot 131 gradually decreases from the semi-circular front end 131a of the front slot 131 towards the transition area 133. The width W3 of the transition area 133 gradually decreases from its front end to its rear end and connects to the rear slot 132. The width W2 of the rear slot 132 maintains a substantially constant width from the transition area 133 towards the semi-circular rear end 132a of the rear slot 132.

[0060] Please refer to the following: Figures 3 to 7 , Figure 9 and Figure 11In this embodiment, the top seat 30 has a first pad 31a and a second pad 31b. The second pad 31b is fixed to the first pad 31a and forms an integral structure with the first pad 31a. The first pad 31a can be made of a material with a higher hardness than the second pad 31b. For example, the first pad 31a can be made of elastic plastic to provide excellent elasticity and comfort. The second pad 31b can be made of a shock-absorbing material, such as memory foam or high-elasticity polyurethane, to improve riding comfort. In this way, the first pad 31a can provide the structural support required by the top seat 30, while the second pad 31b can provide additional cushioning. However, the present invention is not limited to this. For example, the top seat 30 can be made of a single pad or multiple pads.

[0061] The top seat 30 has a front end portion 30a, a rear end portion 30b, and a body portion 30c connecting the front end portion 30a and the rear end portion 30b. The shapes of the front end portion 30a, the rear end portion 30b, and the body portion 30c substantially correspond to the shapes of the front end portion 12a, the rear end portion 12b, and the body portion 12c of the base 10; however, this invention is not limited thereto. Furthermore, the top seat 30 has a retaining portion 32 protruding downwards from its bottom surface. The shape and size of the retaining portion 32 are configured to allow it to pass through the mounting groove 13 of the base 10 at a non-retaining position P1 (e.g., ...) that can be inserted into and exited from the mounting groove 13. Figure 13 (as shown) and the insertable position P2 that can be fixed in the mounting slot 13 (as shown) Figure 5 , 14 The top seat 30 can be detachably fixed to the base 10 by sliding longitudinally between the two sides (as shown).

[0062] In detail, in this embodiment, the latching portion 32 is implemented by two longitudinally arranged and spaced apart cylindrical fasteners 33. Each fastener 33 has a neck 331 and a head 332, wherein the lateral dimension of the head 332 is larger than that of the neck 331. The size design of the head 332 of the fastener 33 ensures that the latching portion 32 is located in the non-latching position P1 (e.g., Figure 13 When shown, it can pass through or out of the front slot 131 of the base 10, while the insert part 32 is in the insert position P2 (as shown). Figure 5 , 14 When (as shown), the neck 331 can mate with the rear slot 132 or even be squeezed by the two opposing side walls 134 of the rear slot 132 (as shown). Figure 6 , 7 (As shown) without shifting left or right, while the head 332 can be locked against the bottom surface 122 of the base plate 12 of the base 10 without shifting up or down, so as to form a stable locking structure, ensuring that the top seat 30 can be firmly connected to the base 10, effectively preventing the top seat 30 from coming loose from the base 10 when the bicycle seat 1 is in use.

[0063] Secondly, such as Figure 4As shown, the front end portion 30a of the top seat 30 has a retaining hole 34 located on its bottom surface, and the retaining hole 34 has an opening 34a that opens toward the rear end portion 30b of the top seat 30. Figure 5 As shown, when the inserting part 32 is in the inserting position P2, the front end 12a of the base 10 passes through the opening 34a and is inserted into the inserting hole 34. In this way, the top seat 30 can be more securely inserted and fixed to the base 10, and ensure that it cannot be dislodged from the base 10 upwards.

[0064] In addition, such as Figure 4 As shown, the top seat 30 has a left locking groove 35a and a right locking groove 35b located on its bottom surface and distributed along its left and right edges, respectively. Figure 7 As shown, when the inserting part 32 is in the inserting position P2, the left edge 15a of the base 10 is inserted into the left inserting groove 35a, and the right edge 15b of the base 10 is inserted into the right inserting groove 35b. In this way, not only is the bonding force between the top seat 30 and the base 10 improved, but also additional protection is provided to effectively prevent lateral sliding and external force damage.

[0065] Furthermore, such as Figure 4 As shown, the rear end 30b of the top seat 30 may have an insert card 36 extending downward from its rear end; as Figure 5 As shown, when the inserting part 32 is in the inserting position P2, the inserting card 36 of the top seat 30 hooks onto the rear end 12b1 of the rear end 12b of the base 10. This enhances the bonding strength between the top seat 30 and the base 10, preventing the rear end 30b of the top seat 30 from detaching from the rear end 12b of the base 10 during use, thus improving the overall structural stability. In this embodiment, the inserting card 36 is made of elastic plastic, and when subjected to external pressure (such as...), it will... Figure 13 When the lever is turned (as shown) or by external force (such as the user's finger) (e.g.) Figure 14 (As shown) It can be compressed inward or expanded outward and deformed, and can return to its original shape when the external force is removed. In this way, it helps the embedded card 36 to hook onto or detach from the rear end 12b1 of the base 10.

[0066] The assembly and disassembly of the top seat 30 and the base 10 are described in detail below. Figure 12 and Figure 13 As shown, during the assembly of the top seat 30 and the base 10, the user can hold the rear end 30b of the top seat 30 and first align the locking part 32 of the top seat 30, more specifically, the head 332 of the buckle 33, with a specific position (i.e., the non-locking position P1) of the wider front slot 131 of the base 10, and insert the head 332 into the front slot 131. Then, as... Figure 14As shown, apply appropriate force towards the insertion position P2, causing the neck 331 of the buckle 33 to slide along the front slot 131 and transition area 133 into the narrower rear slot 132, and be positioned at the insertion position P2. This completes the assembly process, which is quite simple and easy. During assembly, the insertion clip 36 of the top seat 30 elastically deforms upon contact with the top surface 121 of the base 10. When the insertion part 32 slides to the insertion position P2, as... Figure 5 As shown, the neck 331 of the front buckle 33 is located at the front end of the rear slot 132 via the transition area 133, while the neck 331 of the rear buckle 33 is located at the rear end 132a of the rear slot 132. At this time, the insert 36 slides out of the rear end 12b1 of the base 10 and elastically returns to its original shape to hook onto the rear end 12b1 of the base 10. In this way, the user can clearly see and ensure that the top seat 30 has slid into position. In other words, this utility model uses the different widths of the mounting groove 13 along its longitudinal direction to help and guide the top seat 30 to slide relative to the base 10 to complete the assembly. The insert 32 is clamped by the two opposite side hole walls 134 of the mounting groove 13, and the insert 32 abuts against the bottom surface 122 of the base 10 to form a strong insert fastening structure. This ensures that the top seat 30 will not loosen due to vibration or external force during riding, improving the overall riding safety and stability.

[0067] When disassembling the top seat 30, the user first moves the insert clip 36 to cause it to elastically deform and separate from the rear end 12b1 of the base 10, as shown. Figure 14 As shown. Then, the user applies force in the opposite direction, causing the neck 331 of the buckle 33 to slide forward from the engagement position P2 of the narrower rear slot 132 to the non-engaged position P1 of the wider front slot 131. Next, the top seat 30 is lifted upwards, causing the engagement portion 32 of the top seat 30, more specifically, the head 332 of the buckle 33, to exit upwards from the front slot 131, thus completing the removal of the top seat 30. This removal method requires no additional tools, is simple and quick to operate, and effectively improves the convenience and efficiency for users when maintaining and replacing the top seat 30 of the bicycle saddle 1.

[0068] Based on the above technical features, the bicycle seat 1 provided by this utility model has at least the following advantages compared to the prior art:

[0069] 1. Tool-free assembly and disassembly, convenient operation: Through the cooperation between the mounting slot 13 designed in the base 10 and the snap-fit ​​part 32 of the top seat 30, the user can complete the installation and disassembly of the top seat 30 by hand without the use of any tools, which significantly improves the convenience of use and maintenance efficiency;

[0070] 2. Simple structure and excellent stability: The bicycle seat 1's overall structure consists of only two main components: the base 10 and the top seat 30. Combined with a guide-sliding locking mechanism (such as the mounting groove 13 and locking part 32, the locking hole 34 and the front end 12a of the base plate 12, the left and right locking grooves 35a and 35b and the left and right side edges 15a and 15b of the base plate 12, the locking clip 36 and the rear end 12b1 of the rear end 12b of the base plate 12), the assembly is intuitive and ensures good stability of the top seat 30 relative to the base 10 after assembly, preventing wobbling or loosening.

[0071] 3. Smooth assembly guidance and reliable snap-fit ​​effect: The front slot 131, transition area 133 and rear slot 132 with the tapered design, combined with the multi-segment positioning structure of the snap-fit ​​part 32 (such as the double snap-fit ​​body 33 design), can provide guidance and feedback during the sliding assembly process, so that the user can accurately confirm whether the top seat 30 has been snapped and fixed in position.

[0072] In addition to the embodiments disclosed above, without departing from the spirit of the technical features of this utility model, the shape, size, material, and connection method of the base 10 and top seat 30 of the bicycle seat 1 provided by this utility model can have various modifications and variations. For example, the width variation of the mounting groove 13 is not limited to that disclosed in the above embodiments, as long as the width W1 of the front groove hole 131 of the mounting groove 13 is greater than the width W2 of the rear groove hole 132. Alternatively, the width W2 of the rear groove hole 132 is not limited to a uniform width design that maintains a certain length, but can be designed as a multi-stage structure with the width narrowing towards the rear end 132a, so as to adapt to the neck 331 of the buckle body 33 of different sizes, so as to achieve the effect of stage locking and stable connection. For example, the shape of the insert part 32 is not limited to the two cylindrical fasteners 33 disclosed in the above embodiments. It may be a single cylindrical or strip-shaped fastener 33 (longitudinal length is greater than transverse width), or the fastener 33 may not have a head 332 but only a neck 331 that can slide in the mounting groove 13.

[0073] More specifically, for example Figure 15The second preferred embodiment of this utility model discloses a bicycle seat base 50. This base 50 can be used in conjunction with (but is not limited to) the top seat 30 provided in the first preferred embodiment. The only difference between this base 50 and the base 10 provided in the first embodiment is that the mounting groove 53 has a different structure than the mounting groove 13 of the first embodiment. In this embodiment, the mounting groove 53 includes a front slot 531 and a rear slot 532 that is separated from the front slot 531 by a certain distance but arranged longitudinally front to back. The width of the front slot 531 gradually decreases from its front end 531a to its rear end 531b, and the width of the rear slot 532 also gradually decreases from its front end 532a to its rear end 532b. When the base 50 is used in conjunction with the top seat 30 provided in the first embodiment, the front ends 531a and 532a of the front and rear slots 531 and 532 can be regarded as non-embedded positions P1, while the rear ends 531b and 532b of the front and rear slots 531 and 532 can be regarded as embedded positions P2. In this way, for the two longitudinally arranged and spaced buckles 33 of the embedded part 32 of the top seat 30, their heads 332 can pass through the front slot 531 and the rear slot 532 respectively in the non-embedded position P1. When the two buckles 33 slide backward from the non-embedded position P1 of the front and rear slots 531 and 532 to the embedded position P2, as described in the first embodiment above, the heads 332 of each buckle 33 will abut against the bottom surface 122 of the base 10. At this time, the necks 331 of each buckle 33 will abut against the hole walls of the front slot 531 and the rear slot 532 respectively. In this way, the purpose of this utility model can also be achieved. Moreover, compared with the base 10 provided in the first embodiment, the base 50 provided in this embodiment has better structural strength because there is a bridging part 55 between the front slot 531 and the rear slot 532.

[0074] For example, Figure 16The present invention discloses a bicycle saddle base 60 according to a third preferred embodiment. This base 60 can be used in conjunction with (but is not limited to) the top mount 30 provided in the first preferred embodiment. The only difference between this base 60 and the base 10 provided in the first embodiment is the mounting groove structure. In this embodiment, the mounting groove 63 is formed by a single slot extending longitudinally. The width of the mounting groove 63 gradually decreases from its front end 631 to its rear end 632, and the two opposing walls of the mounting groove 63 extending longitudinally are respectively provided with teeth 633. When the base 60 is used in conjunction with the top seat 30 provided in the first embodiment, the front end 631 of the mounting groove 63 can be regarded as the non-embedded position P1, and the rear end 632 can be regarded as the embedded position P2. In this way, the head 332 of the buckle 33 of the embedded part 32 of the top seat 30 can pass into and out of the mounting groove 63 at the non-embedded position P1. When the buckle 33 slides backward from the non-embedded position P1 to the embedded position P2, as described in the first embodiment above, the head 332 of the buckle 33 will abut against the bottom surface 122 of the base 10. At this time, the neck 331 of the buckle 33 will abut against the wall of the mounting groove 63. In this way, the purpose of this utility model can also be achieved. Furthermore, when the locking portion 32 of the top seat 30 slides longitudinally relative to the base 60 between the non-locking position P1 and the locking position P2, the neck 331 of the buckle 33 will continuously pass over each tooth 633a of the toothed portion 633, allowing the user to feel significant vibration feedback at different sliding stages until the locking portion 32 stops at the non-locking position P1 or the locking position P2. This ensures that the user can reliably slide the top seat 30 to the disengaged position or the final fixed position. In this embodiment, an arc-shaped positioning recess 633b is formed between two adjacent teeth 633a of the toothed portion 633. The width of these positioning recesses 633b gradually decreases from the front end 631 to the rear end 632 of the mounting groove 63; however, this utility model is not limited to this. For example, these positioning recesses 633b can have various width configurations, thereby one or more of these positioning recesses 633b can be used as non-embedded positions P1, and one or more of the remaining positioning recesses 633b can be used as embedded positions P2. In this way, the base 60 can be used with the top seat 30 having one or more fasteners 33, so that when the top seat 30 and the base 60 are assembled, the fasteners 33 can pass through the mounting groove 63 from the specific positioning recesses 633b, or be fixed in the specific positioning recesses 633b, so that the top seat 30 can be firmly connected to the base 60.

[0075] Finally, it must be stated again that the constituent elements disclosed in the above embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of this case. Substitutions or variations of other equivalent elements should also be covered by the patent protection scope of this case.
