Description

Technical Field

[0001] This utility model relates to the field of watercraft technology, and in particular to a folding mechanism for watercraft. Background Technology

[0002] In the field of water sports and operations, various water vehicles such as kayaks, paddleboards, and inflatable boats are widely used in recreational activities, water rescue, and fishing operations due to their flexibility and convenience. These vehicles are usually equipped with control sticks to stabilize the user's body. Users can stand safely on the water vehicle by firmly gripping the control sticks with both hands. The rationality of the control stick design directly affects the user experience and practicality of the water vehicle.

[0003] Currently, most watercraft on the market use fixed control levers, meaning the lever is rigidly connected to the vehicle body via welding or bolts, and cannot be folded. While this type of fixed control lever provides stable grip during use, it reveals significant limitations when not in use, especially during transport and storage. Specifically, the inability to fold the control lever significantly increases the overall size and space occupied by the watercraft. When transporting the watercraft by vehicle, the protruding control lever is highly susceptible to collisions with other objects, easily causing damage to the lever or the vehicle itself. During storage, the fixed control lever also makes it difficult to neatly arrange the vehicle in limited spaces such as warehouses or home storage rooms, resulting in wasted space and considerable inconvenience for users.

[0004] With the increasing popularity of water sports and the growing demand for portable vehicles, solving the transportation and storage problems caused by the inability to fold control sticks has become a pressing technological direction for improvement in this field. Therefore, developing a mechanism that enables the folding and storage of control sticks for water vehicles is of significant practical importance for optimizing vehicle structure and improving its portability.

[0005] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a folding mechanism for water vehicles, which aims to solve the problem of large space occupation during the transportation and storage of water vehicles in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A folding mechanism for a watercraft includes: a gripping assembly having a first engaging portion; a support member having the gripping assembly mounted on it, the support member having a second engaging portion cooperating with the first engaging portion to define an installation angle of the gripping assembly on the support member; and a locking assembly for locking the gripping assembly onto the support member. Rotation of the locking assembly locks or releases the installation angle of the gripping assembly on the support member. When the locking assembly rotates in a first direction, it compresses the support member or the gripping assembly, causing them to abut against each other, thereby locking the engagement between the first engaging portion and the second engaging portion. When the locking assembly rotates in a second direction, the abutment between the support member and the gripping assembly is released, allowing the first engaging portion and the second engaging portion to move relative to each other.

[0009] The locking assembly includes a pivot and a locking member. One end of the pivot passes through the support and the gripping assembly and is hinged to the cam portion of the locking member. The other end of the pivot cannot pass through the support and the gripping assembly. The cam portion includes a first abutment surface and a second abutment surface. The distance from the first abutment surface to the cam rotation axis is greater than the distance from the second abutment surface to the cam rotation axis. When the locking member rotates in a first direction, the cam portion presses against the support or the gripping assembly through the first abutment surface, causing the support and the gripping assembly to abut against each other, thereby locking the engagement relationship between the first and second joints. When the locking member rotates in a second direction, there is no relative pressure between the second abutment surface and the support or the gripping assembly, and the support and the gripping assembly are released from their abutment relationship, allowing the first and second joints to move relative to each other. By rotating the locking member, the mounting angle of the gripping assembly on the support can be locked, or the locked state of the mounting angle can be released.

[0010] The locking assembly includes a pivot, a fastener, and a locking member. One end of the pivot passes through the support and the gripping assembly and is fixedly connected to the fastener. The other end of the pivot is hinged to the cam portion of the locking member. The cam portion includes a first abutment surface and a second abutment surface. The distance from the first abutment surface to the cam rotation axis is greater than the distance from the second abutment surface to the cam rotation axis. When the locking member rotates in a first direction, the cam portion presses against the support or the gripping assembly through the first abutment surface, causing the support and the gripping assembly to abut against each other, thereby locking the engagement relationship between the first and second joints. When the locking member rotates in a second direction, there is no relative pressure between the second abutment surface and the support or the gripping assembly, the support and the gripping assembly are released from their abutment relationship, and the first and second joints can move relative to each other. By rotating the locking member, the mounting angle of the gripping assembly on the support can be locked, or the locked state of the mounting angle can be released.

[0011] The support member or gripping assembly has a contact surface on the side near the locking member for fitting the cam portion, or the support member has an abutment on one side with a contact surface for fitting the cam portion.

[0012] The contact surface is an arc-shaped surface.

[0013] The support includes a support body, both ends of which are bent toward the gripping component to form two opposing second joint portions; the support body and the second joint portions define an accommodating space for one end of the gripping component to extend into; the locking component presses the first joint portion through the second joint portion to lock the mounting angle of the gripping component on the support.

[0014] The first joint is provided with a first limiting part, and the second joint is provided with a second limiting part that cooperates with the first limiting part, so as to limit the installation angle of the gripping component on the support when the first joint and the second joint are engaged.

[0015] The pivot member is provided with a flat portion, and the gripping assembly is provided with an installation channel for one end of the pivot member to pass through. The installation channel has a flat section at one end near the locking member to accommodate the flat portion.

[0016] The gripping assembly includes a rotating component, a gripping component, and a clamping structure. One end of the rotating component is pivotally connected to the support component, and the other end of the rotating component has an opening. The mounting end of the gripping component extends into the cavity of the rotating component through the opening. The length of the gripping component within the cavity of the rotating component can be adjusted along the direction of the opening. The clamping structure is used to fix the relative position of the gripping component on the rotating component.

[0017] The rotating component extends outward from one end of the opening to form a tube opening, and the clamp structure is sleeved on the outer periphery of the tube opening; a connecting component is also provided between the tube opening and the gripping component.

[0018] Compared to existing technologies, this utility model provides a folding mechanism for watercraft, comprising:

[0019] The device includes a gripping assembly with a first engaging portion; a support member on which the gripping assembly is mounted, and a second engaging portion on which the gripping assembly engages with the first engaging portion to limit the installation angle of the gripping assembly on the support member; and a locking assembly for locking the gripping assembly onto the support member. Rotation of the locking assembly locks or releases the installation angle of the gripping assembly on the support member. When the locking assembly rotates in a first direction, it presses against the support member or the gripping assembly, causing them to abut against each other, thereby locking the engagement between the first engaging portion and the second engaging portion. When the locking assembly rotates in a second direction, the abutment between the support member and the gripping assembly is released, allowing the first engaging portion and the second engaging portion to move relative to each other.

[0020] This utility model relates to a folding mechanism for watercraft. The first connecting part on the grip component cooperates with the second connecting part on the support to limit the installation angle of the grip component on the support. By rotating the locking component, the relative relationship between the support and the grip component is changed to lock or unlock the installation angle, enabling the grip component to have a folding function. This solves the problems of large space occupation and easy collision during transportation and storage of traditional fixed control levers, significantly reducing the space occupied in the non-use state and improving portability.

[0039] The components include: gripping assembly 41, rotating part 411, nozzle part 4111, first connecting part 4112, first limiting part 4113, gripping part 412, clamp structure 413, base 4131, adjusting part 4132, mounting channel 414, flat section 4141, support part 42, support body 421, second connecting part 422, wavy end 423, second limiting part 424, pivot part 431, first pivot part 4311, first limiting part 4312, second pivot part 4313, second limiting part 4314, flat section 4315, locking part 432, cam part 4321, first abutting surface 4322, second abutting surface 4323, gripping part 4324, fastener 433, abutting part 44, contact surface 441, sleeve part 45, support part 451, and U-shaped groove 452. Detailed Implementation

[0040] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0041] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0042] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0043] When not in use, especially during transportation and storage, the inability to fold the control levers of watercraft presents significant limitations. Specifically, the non-foldable control levers significantly increase the overall size and space occupied by the watercraft. During vehicle transport, the protruding control levers are highly susceptible to collisions with other objects, easily causing damage to the control levers or the vehicle itself. During storage, fixed control levers also make it difficult to neatly arrange the vehicle in limited spaces such as warehouses and home storage rooms, resulting in wasted space and inconvenience to users. To address the shortcomings of the existing non-foldable control levers in watercraft, this invention provides a folding mechanism for watercraft. Please refer to [link / reference]. Figures 1-17 ,include:

[0044] The system includes: a gripping component 41, on which a first engaging portion 4112 is provided; a support member 42, on which the gripping component 41 is mounted, and on which a second engaging portion 422 is provided that cooperates with the first engaging portion 4112 to limit the installation angle of the gripping component 41 on the support member 42; and a locking component for locking the gripping component 41 onto the support member 42. Rotation of the locking component locks the gripping component 41 onto the support member 42. The installation angle on 2, or the locking state of the installation angle is released; when the locking component rotates in the first direction, the locking component presses the support member 42 or the gripping component 41, so that the support member 42 and the gripping component 41 abut against each other, thereby locking the cooperation relationship between the first joint 4112 and the second joint 422; when the locking component rotates in the second direction, the support member 42 and the gripping component 41 are released from the abutment relationship, and the first joint 4112 and the second joint 422 can move relative to each other.

[0045] This utility model relates to a folding mechanism for watercraft. The first connecting part 4112 on the grip component 41 cooperates with the second connecting part 422 on the support member 42 to limit the installation angle of the grip component 41 on the support member 42. By rotating the locking component, the relative relationship between the support member 42 and the grip component 41 is changed to lock or unlock the installation angle, so that the grip component 41 has a folding function. This solves the problems of large space occupation and easy collision when transporting and storing traditional fixed control levers, significantly reduces the space occupied in the non-use state, and improves portability.

[0046] In the first embodiment of this application, please refer to Figures 1-3 , Figure 17The locking assembly includes a pivot member 431 and a locking member 432. One end of the pivot member 431 passes through the support member 42 and the gripping assembly 41, and is hinged to the cam portion 4321 of the locking member 432. The other end of the pivot member 431 cannot pass through the support member 42 and the gripping assembly 41, so that the pivot member 431 is limited to the support member 42. The cam portion 4321 includes a first abutment surface 4322 and a second abutment surface 4323. The distance from the first abutment surface 4322 to the rotation axis of the cam portion 4321 is greater than the distance from the second abutment surface 4323 to the rotation axis of the cam portion 4321. When the locking member 432 rotates in a first direction, the cam portion 4321 passes through the... The first abutment surface 4322 presses against the support member 42 or the gripping component 41, so that the support member 42 and the gripping component 41 abut against each other, thereby locking the engagement relationship between the first joint 4112 and the second joint 422; when the locking member 432 rotates in a second direction opposite to the first direction, there is no relative compression between the second abutment surface 4323 and the support member 42 or the gripping component 41, the abutment relationship between the support member 42 and the gripping component 41 is released, and the first joint 4112 and the second joint 422 can move relative to each other; by rotating the locking member 432, the installation angle of the gripping component 41 on the support member 42 is locked, or the locked state of the installation angle is released.

[0047] In the first embodiment, with the second connecting portion 422 on the support member 42 located outside the first connecting portion 4112 on the gripping assembly 41, a structure included in the first embodiment will be described. In this case, when the locking member 432 rotates in the first direction, the cam portion 4321 presses the second connecting portion 422 on the support member 42 through the first abutment surface 4322, so that the support member 42 and the gripping assembly 41 abut against each other, thereby locking the engagement relationship between the first connecting portion 4112 and the second connecting portion 422. Of course, alternatively, when the second connecting portion 422 of the support member 42 is located inside the first connecting portion 4112 on the gripping assembly 41, when the locking member 432 rotates in the first direction, the cam portion 4321 presses the first connecting portion 4112 on the gripping assembly 41 through the first abutment surface 4322, so that the support member 42 and the gripping assembly 41 abut against each other, thereby locking the engagement relationship between the first connecting portion 4112 and the second connecting portion 422.

[0048] Further, in the first embodiment, the pivot member 431 includes a first pivot portion 4311 and a first limiting portion 4312, which are located at both ends of the pivot member 431. The first pivot portion 4311 passes through the support member 42 and the grip assembly 41 from the side away from the locking member 432 and is hinged to the cam portion 4321 of the locking member 432. The first limiting portion 4312 is located outside the support member 42 and the grip assembly 41 (i.e., the first limiting portion 4312 cannot pass through the support member 42 and the grip assembly 41) to limit the pivot member 431 to the support member 42. The locking member 432 includes a cam portion 4321 and a grip portion 4324 extending along the periphery of the cam portion 4321. The cam portion 4321 is hinged to the first pivot portion 4311 by a pin. The grip portion 4324 allows the user to rotate the locking member 432 in a first direction or a second direction.

[0049] Specifically, when the user rotates the locking member 432 in the first direction, the cam portion 4321 rotates synchronously and presses against one side of the support member 42 through the first abutment surface 4322 of the cam portion 4321. The other side of the support member 42 presses against the first limiting portion 4312. In this case, the support member 42 abuts against the gripping component 41, locking the engagement relationship between the first connecting portion 4112 and the second connecting portion 422, thereby locking the installation angle of the gripping component 41 on the support member 42; when the user rotates in the second direction (i.e., the direction opposite to the first direction), the locking member 42 rotates simultaneously. When the locking member 432 is rotated in the opposite direction, the cam part 4321 rotates synchronously, and the first abutting surface 4322 of the cam part 4321 disengages from the support member 42. The squeezing force of the cam part 4321 on the support member 42 in the setting direction of the pivot member 431 disappears. In this case, the support member 42 and the gripping component 41 are released from the abutting relationship, and the first connecting part 4112 and the second connecting part 422 can move relative to each other. At this time, the user can adjust the installation angle of the gripping component 41 on the support member 42 (that is, rotate the gripping component 41 along the axis of the pivot member 431).

[0050] Furthermore, the first direction refers to the direction in which the locking member 432 rotates toward or away from the gripping assembly 41, and its specific rotation direction is determined by the relative positional relationship between the first abutment surface 4322 and the second abutment surface 4323 on the circumference of the cam portion 4321; the second direction refers to the rotation direction opposite to the first direction. Specifically, as... Figure 17As shown, when the arc surface corresponding to the cam portion 4321 at point G is the first abutment surface 4322 and the arc surface corresponding to the cam portion 4321 at point H is the second abutment surface 4323, the first direction refers to the direction in which the locking member 432 rotates towards the side closer to the gripping component 41, and the second direction refers to the direction in which the locking member 432 rotates away from the gripping component 41. In the embodiments of this application, the direction in which the locking member 432 rotates towards the side closer to the gripping component 41 is taken as the first direction and the direction in which the locking member 432 rotates away from the gripping component 41 is taken as the second direction. The operation process of locking the gripping component 432 on the support member 42 to lock the mounting angle of the gripping component 41 on the support member 42 or to release the locked state of the mounting angle is described. Alternatively, when the arc surface corresponding to the cam portion 4321 at point H is the first abutment surface 4322 and the arc surface corresponding to the cam portion 4321 at point G is the second abutment surface 4323, the first direction refers to the direction in which the locking member 432 rotates away from the gripping component 41, and the second direction refers to the direction in which the locking member 432 rotates towards the gripping component 41. Of course, the relative positions of the first abutment surface 4322 and the second abutment surface 4323 can also be changed to alter the rotation direction of the locking member.

[0051] It should be noted that when the locking member 432 rotates in the second direction, there is no relative pressure between the second abutment surface 4323 and the support member 42 or the gripping component 41. This lack of relative pressure includes both contact without relative pressure and no contact at all. In the embodiments of this application, preferably, when the locking member 432 rotates in the second direction, there is contact between the second abutment surface 4323 and the support member 42 or the gripping component 41, but no relative pressure. Furthermore, since the first abutment surface 4322 and the second abutment surface 4323 on the cam portion 4321 are continuous, the locking member 432 and the support member 42 (or the gripping component 41) always maintain a surface contact relationship, which is beneficial for improving the adjustment efficiency of the locking member 432 and ensuring... The locking member 432 ensures stability during rotation. Furthermore, the cam part 4321's structural design allows the user to simply rotate the locking member 432 to lock or release the installation angle of the grip component 41 on the support member 42, making operation simple, efficient, and requiring no complex tools. The first connecting part 4112 and the second connecting part 422 work together to limit the installation angle of the grip component 41 on the support member 42. Rotating the locking member 432 causes the support member 42 to abut against the grip component 41, further fixing the installation angle. This dual cooperation ensures the stability of the grip component 41's angle during use (e.g., when the user stands to operate the watercraft), preventing swaying and guaranteeing safety and comfort.

[0052] Furthermore, the first abutment surface 4322 and the second abutment surface 4323 on the periphery of the cam portion 4321 are continuous, that is, the two are smoothly connected in the circumferential contour of the cam portion 4321, rather than two independent and disconnected surfaces. This continuity allows the locking member 432 to achieve seamless switching between the cam portion 4321 and the support member 42 (or the grip component 41) during rotation, thereby making the transition between the first abutment surface 4322 and the second abutment surface 4323 smoother and improving the smoothness and reliability of the folding mechanism operation.

[0053] In the second embodiment of this application, please refer to Figures 4-8 , Figure 17 The locking assembly includes a pivot 431, a fastener 433, and a locking member 432. One end of the pivot 431 passes through the support member 42 and the gripping assembly 41 and is fixedly connected to the fastener 433. The other end of the pivot 431 is hinged to the cam portion 4321 of the locking member 432, so that the pivot 431 is limited to the support member 42. The cam portion 4321 includes a first abutment surface 4322 and a second abutment surface 4323. The distance from the first abutment surface 4322 to the rotation axis of the cam portion 4321 is greater than the distance from the second abutment surface 4323 to the rotation axis of the cam portion 4321. When the locking member 432 rotates in a first direction, the cam portion 4321 passes through the support member 42. The first abutment surface 4322 presses against the support member 42 or the gripping component 41, so that the support member 42 and the gripping component 41 abut against each other, thereby locking the engagement relationship between the first joint 4112 and the second joint 422; when the locking member 432 rotates in a second direction opposite to the first direction, there is no relative compression between the second abutment surface 4323 and the support member 42 or the gripping component 41, the abutment relationship between the support member 42 and the gripping component 41 is released, and the first joint 4112 and the second joint 422 can move relative to each other; by rotating the locking member 432, the installation angle of the gripping component 41 on the support member 42 is locked, or the locked state of the installation angle is released.

[0054] In the second embodiment, the structure included in the second embodiment is described with the second connecting portion 422 on the support member 42 located outside the first connecting portion 4112 on the gripping assembly 41. Similarly, when the locking member 432 rotates in the first direction, the cam portion 4321 presses the second connecting portion 422 on the support member 42 through the first abutting surface 4322, so that the support member 42 and the gripping assembly 41 abut against each other, thereby locking the engagement relationship between the first connecting portion 4112 and the second connecting portion 422. Of course, alternatively, when the second connecting portion 422 of the support member 42 is located inside the first connecting portion 4112 on the gripping assembly 41, when the locking member 432 rotates in the first direction, the cam portion 4321 presses the first connecting portion 4112 on the gripping assembly 41 through the first abutting surface 4322, so that the support member 42 and the gripping assembly 41 abut against each other, thereby locking the engagement relationship between the first connecting portion 4112 and the second connecting portion 422.

[0055] Further, in the second embodiment, the fastener 433 and the locking member 432 are located on opposite sides of the support member 42, and the pivot member 431 includes a second pivot portion 4313 and a second limiting portion 4314. The second pivot portion 4313 and the second limiting portion 4314 are located at both ends of the pivot member 431. The second pivot portion 4313 is hinged to the cam portion 4321 of the locking member 432. The second limiting portion 4314 passes through the support member 42 and the grip assembly 41 from the side where the locking member 432 is located and is fixedly connected to the fastener 433 to limit the pivot member 431 to the support member 42. The locking member 432 includes a cam portion 4321 and a grip portion 4324 extending along the periphery of the cam portion 4321. The cam portion 4321 is hinged to the second pivot portion 4313 by a pin. The grip portion 4324 allows the user to rotate the locking member 432 in a first direction or a second direction.

[0056] Specifically, when the user rotates the locking member 432 in the first direction, the cam portion 4321 rotates synchronously and presses against one side of the support member 42 through the first abutment surface 4322 of the cam portion 4321. The other side of the support member 42 presses against the fastener 433. In this situation, the support member 42 abuts against the grip component 41, locking the engagement relationship between the first coupling portion 4112 and the second coupling portion 422, thereby locking the installation angle of the grip component 41 on the support member 42; when the user rotates in the second direction (i.e., the opposite of the first direction), the user rotates in the second direction (i.e., the opposite of the first direction). When the locking member 432 is rotated (direction), the cam part 4321 rotates synchronously, and the first abutting surface 4322 of the cam part 4321 disengages from the support member 42. The squeezing force of the cam part 4321 on the support member 42 in the direction of the pivot member 431 disappears. In this case, the support member 42 and the gripping component 41 are released from the abutting relationship, and the first connecting part 4112 and the second connecting part 422 can move relative to each other. At this time, the user can adjust the installation angle of the gripping component 41 on the support member 42 (that is, rotate the gripping component 41 along the axis of the pivot member 431).

[0057] In both the first and second embodiments, the pivot member 431 includes a pivot portion and a limiting portion. However, due to the difference in the structural shape of the pivot member 431, the installation direction of the pivot member 431 differs between the first and second embodiments (the direction in which the pivot member 431 passes through the support member 42 and the gripping component 41 in the second embodiment is opposite to the direction in which the pivot member 431 passes through the support member 42 and the gripping component 41 in the first embodiment). This results in the two embodiments limiting the pivot member 431 to the support member 42 in different ways. The specific structure of this structure has been described above and will not be repeated here. Furthermore, the descriptions of the first abutment surface 4322 and the second abutment surface 4323 on the periphery of the cam portion 4321, the definitions of the first and second directions, and the description of no relative compression between the second abutment surface 4323 and the support member 42 or the gripping component 41 are the same in the first and second embodiments and will not be repeated here.

[0058] In the second embodiment, the fastener 433 is a nut, and the outer periphery of the second limiting part 4314 is provided with threads. The second limiting part 4314 passes through the support member 42 and the gripping assembly 41 from the locking member 432 and is screwed and fixed to the nut to ensure the stability of the pivot member 431 during installation. During use, the water vehicle will be continuously subjected to dynamic loads such as water flow impact, engine vibration, and bumps. The nut, through the threaded connection, cooperates with the pivot member 431 to provide continuous and adjustable lateral compression force, tightly pressing the support member 42 and the gripping assembly 41 together, effectively eliminating the gap between the two supports. One end of the pivot member 431 is connected to the locking member. The cam portion 4321 of 432 is hinged, and the other end of the pivot member 431 is threaded with the fastener 433. By adjusting the relative position of the fastener 433 on the pivot member, it can accommodate pivot members of different lengths, thereby avoiding the problem of poor installation effect of the pivot member 431 on the support member 42 due to the pivot member being too long or too short. By limiting the installation of both ends of the pivot member 431 through screwing and hinge, it can avoid the failure of a single locking structure (such as the decrease in locking force due to wear of the cam portion 4321), ensuring that the gripping component 41 will not rotate unexpectedly during operation (such as rotation), thus improving the safety of use. When adjusting the installation angle of the gripping component 41 on the support member 42, the basic clamping force can also be adjusted by appropriately loosening the nut, avoiding adjustment jamming due to excessive tightness or inaccurate angle positioning due to excessive looseness, thus ensuring the reliability of parallel locking and the flexibility of adjustment.

[0059] Furthermore, with the structure in the second embodiment, when maintenance or replacement of the grip component 41, support member 42, or pivot member 431 is required, the pivot member 431 can be easily removed from the support member 42 and grip component 41 simply by unscrewing the nut, thus facilitating the separation of the various components. In contrast, in embodiment 1, since the pivot member 431 and locking member 432 are hinged, separating the pivot member 431 and locking member 432 may require more complex operations and may even require damage to part of the structure, which undoubtedly increases the cost and difficulty of maintenance. Based on the advantages of the aforementioned second embodiment, the subsequent embodiments of this application are described on the basis of the second embodiment, and the first embodiment is only one way to realize the foldable function of the grip component 41.

[0060] Furthermore, such as Figures 1-17 As shown, the support member 42 or the gripping assembly 41 has a contact surface 441 on the side near the locking member 432 for adapting to the cam portion 4321, or the support member 42 has an abutment member 44 on one side, and the abutment member 44 has a contact surface 441 for adapting to the cam portion 4321.

[0061] In this application, the support member 42 or the gripping assembly 41 has a contact surface 441 on the side near the locking member 432. When the locking member 432 rotates in the first direction, the first abutting surface 4322 of the cam portion 4321 presses against the contact surface 441, causing the support member 42 and the gripping assembly 41 to abut against each other, thereby fixing the engagement relationship between the first coupling portion 4112 and the second coupling portion 422. When the locking member 432 rotates in the second direction, the second abutting surface 4323 of the cam portion 4321 is in relative contact with the contact surface 441 without pressing, or the second abutting surface 4323 is not in contact with the contact surface 441. At this time, the support member 42 and the gripping assembly 41 are released from the abutting relationship, and the first coupling portion 4112 and the second coupling portion 422 can move relative to each other; or, the support member 42 has a contact surface 441 on the side near the locking member 432. A side abutment 44 is provided, and a contact surface 441 is provided on the abutment 44. When the locking member 432 rotates in the first direction, the first abutment surface 4322 of the cam portion 4321 and the contact surface 441 on the abutment 44 press against each other, causing the support member 42 and the gripping assembly 41 to abut against each other, thereby fixing the engagement relationship between the first joint portion 4112 and the second joint portion 422. When the locking member 432 rotates in the second direction, the second abutment surface 4323 of the cam portion 4321 and the contact surface 441 on the abutment 44 are in relative contact without pressing, or the second abutment surface 4323 of the cam portion 4321 and the contact surface 441 on the abutment 44 are not in contact. At this time, the support member 42 and the gripping assembly 41 are released from the abutment relationship, and the first joint portion 4112 and the second joint portion 422 can move relative to each other. Furthermore, in the embodiments of this application, when an abutment 44 is provided on one side of the support member 42, a gasket is provided between the abutment 44 and the first joint portion 4112 or the second joint portion 422. In the corresponding second embodiment, a gasket (not shown in the figure) is provided between the fastener 433 and the first joint portion 4112 or the second joint portion 422. In the corresponding first embodiment, a gasket is provided between the first limiting portion 4312 and the first joint portion 4112 or the second joint portion 422. The provision of the gasket, while realizing pressure transmission, avoids the extrusion force between the abutment 44 and the fastener 433 (or the first limiting portion 4312) from damaging the first joint portion 4112 or the second joint portion 422, thus affecting the service life of the support member 42 or the gripping component 41.

[0062] Preferably, during the rotation of the locking member 432 in the first direction, initially the second abutment surface 4323 does not contact the contact surface 441 on the abutment member 44 (i.e., there is a gap between the second abutment surface 4323 and the contact surface 441), and then the first abutment surface 4322 contacts the contact surface 441, locking the clamping member 432 to lock the installation angle of the gripping component 41 on the support member 42; the change in the contact state between the abutment surface and the contact surface 441 from no pressure to pressure is continuous and gradual, rather than abrupt. This smooth transition can avoid the operational jamming and impact caused by sudden changes in the contact state (such as from separation to contact), making the angle adjustment process smoother; the continuous contact formed by the continuous first and second abutment surfaces 4323 and the contact surface 441 makes the contact area a continuous surface contact, which can disperse the contact stress when the cam part 4321 rotates, avoiding excessive local pressure that causes premature wear of the contact surface 441 or the cam part 4321. As the locking member 432 rotates in the second direction from the state of the locking grip assembly 41 mounted on the support member 42 at the installation angle, the first abutment surface 4322 gradually disengages from the contact surface 441, and there is a gap between the second abutment surface 4323 and the contact surface 441. At this time, since the locking member 432 releases the restriction on the installation angle of the grip assembly 41 on the support member 42, and there is a gap between the second abutment surface 4323 and the contact surface 441, the second joint 422 is given deformation space relative to the disengagement from the first joint 4112, thereby facilitating the subsequent adjustment of the installation angle of the grip assembly 41 and the support member 42.

[0063] In an optional embodiment, the corresponding structure is not shown in the figure. The contact surface 441 is located on the side of the support member 42 or the gripping assembly 41 to adapt to the cam part 4321. When the locking member 432 rotates in the first direction, the first abutting surface 4322 of the cam part 4321 directly acts on the support member 42 or the gripping assembly 41 through the contact surface 441. The squeezing force of the cam part 4321 can be converted into the abutting force between the support member 42 and the gripping assembly 41 more directly and efficiently, ensuring that the first joint part 4112 and the second joint part 422 are tightly fitted, improving locking efficiency and reliability. At the same time, by directly integrating the contact surface 441 onto the support member 42 or the gripping assembly 41, the structure is simple, reducing assembly errors and complexity.

[0064] In an optional embodiment, see [reference] Figures 1-17A contact member 44 is provided on one side of the support member 42 to contact the cam portion 4321. A through hole is provided in the middle of the contact member 44. Based on the structure of the second embodiment, one end of the pivot member 431 first passes through the contact member 44, then through the support member 42 and the gripping component 41, and is screwed and fixed to the fastener 433. The surface of the contact member 44 forms a contact surface 441 for the cam portion 4321 to abut. The first contact surface 4322 of the cam portion 4321 achieves force transmission by contacting the contact surface 441. Compared to directly setting the contact surface 441 on the support member 42 or the gripping member 412, indirectly transmitting the pressing force of the cam portion 4321 to the support member 42 or the gripping component 41 through the abutment member 44 has the following advantages: the abutment member 44 can be processed as an independent component, and the flatness, curvature, and other precision requirements of its contact surface 441 are easier to achieve, which can more accurately adapt to the abutment requirements of the cam portion 4321 on the locking member 432, improving the stability of locking and unlocking; the abutment member 44 needs to be in frequent contact with the cam portion 4321 (enduring compression and friction), so it can be made of wear-resistant, high-strength, or appropriately elastic materials, while the support member 42 or the gripping component 41 can be made of other materials according to the requirements of structural strength, lightweighting, etc., while ensuring While ensuring reliable contact, the overall cost is reduced. If the contact surface 441 wears or deforms due to long-term use, only the independent abutment 44 needs to be replaced, without replacing the entire support 42, thus reducing maintenance costs. When the support 42 is designed with a complex shape to connect to the watercraft or adapt to the grip component 41, the independent abutment 44 can be flexibly adjusted in terms of installation position and angle to ensure the fitting accuracy between the contact surface 441 and the cam part 4321, avoiding the influence of the shape and structure of the support 42. The cam part 4321 presses the support 42 or the grip component 41 through the abutment 44, increasing the pressing area and making the transmission of pressing force more uniform and stable, thereby improving the stability of the angle of the grip component 41 when in use (standing and operating the watercraft).

[0065] Further, please refer to Figures 1-17 Preferably, the contact surface 441 is an arc-shaped surface. The curvature of the arc-shaped surface matches the rotation trajectory of the cam portion 4321, ensuring that the first and second abutment surfaces 4323 maintain stable contact with the arc-shaped surface during the rotation of the cam portion 4321. The arc-shaped surface reduces the frictional resistance when the cam portion 4321 rotates, making locking and unlocking operations smoother and less strenuous; compared to planar contact, the arc-shaped surface can disperse contact stress, reduce local wear, and extend the service life of the component; the arc-shaped surface has a higher fit with the cam portion 4321, increasing the contact area between the first and second abutment surfaces 4323 and the contact surface 441, and improving locking stability. Alternatively, the contact surface 441 can also be set as a plane.

[0066] Furthermore, the support member 42 includes a support body 421 connected to the water vehicle, with both ends of the support body 421 bent toward the gripping assembly 41 to form two opposing second joint portions 422; the support body 421 and the second joint portions 422 define an accommodating space for one end of the gripping assembly 41 to extend into, and the locking assembly presses the first joint portion 4112 through the second joint portion 422 to lock the mounting angle of the gripping assembly 41 on the support member 42.

[0067] In the third embodiment of this application, please refer to Figure 11 The first connecting part 4112 is a sheet-like structure formed by extending the lower end of the gripping component 41, and the second connecting part 422 is a sheet-like structure formed by bending the two ends of the supporting body 421. The sheet-like structure formed by extending the lower end of the gripping component 41 defines an accommodating space for the second connecting parts 422 at both ends of the supporting body 421 to extend into. At this time, the first connecting part 4112 is located outside the second connecting part 422. When the locking member 432 rotates in the first direction, the first abutting surface 4322 of the cam part 4321 presses against the first connecting part 4112 on one side. The first limiting part 4312 in the first embodiment or the fastener 433 in the second embodiment abuts against the first connecting part 4112 on the other side, so as to cause the first connecting part 4112 and the second connecting part 422 to be pressed against each other and form an abutment. The first connecting part 4112 and the second connecting part 422 are in planar contact. At this time, the cooperation relationship between the two is fixed under the action of the relative friction force of the first connecting part 4112 and the second connecting part 422.

[0068] In the fourth embodiment of this application, please refer to Figure 12The first connecting portion 4112 is a sheet-like structure formed by extending the lower end of the gripping component 41. At least two of these first connecting portions 4112 are provided, and the two first connecting portions 4112 are arranged opposite each other. The second connecting portion 422 is two sheet-like structures formed by bending the two ends of the supporting body 421. When the gripping component 41 is mounted on the support member 42, the first connecting portion 4112 and the second connecting portion 422 on the same side are arranged opposite each other. In this embodiment, the first connecting portion 4112 and the second connecting portion 422 are planar sheet-like structures. The supporting body 421 and the two oppositely arranged second connecting portions 422 form a U-shaped structure. The lower end of the gripping component 41 extends into the U-shaped structure. At this time, the second connecting portion 422 is located at the first connecting portion 4112. On the outer side of 112; when the locking member 432 rotates in the first direction, the first abutting surface 4322 of the cam portion 4321 presses against the second connecting portion 422 near the locking member 432. The first limiting portion 4312 in the first embodiment or the fastener 433 in the second embodiment abuts against the second connecting portion 422 on the other side, so as to cause the second connecting portion 422 to be relatively pressed against the first connecting portion 4112 to form an abutment. The first connecting portion 4112 and the second connecting portion 422 are in planar contact. At this time, the mating relationship between the two is fixed under the action of the relative friction force between the first connecting portion 4112 and the second connecting portion 422 (the properties of the materials of the first connecting portion 4112 and the second connecting portion 422 themselves). In this embodiment, the first connecting portion 4112 and the second connecting portion 422 are planar, that is, the surfaces of the two connecting portions have no teeth, wavy ends or protrusions. The symmetrical design of the double-sided compression ensures that the grip component 41 is subjected to uniform force, avoiding tilting or loosening caused by unilateral compression and improving the structural stability of the grip component 41 during use; the U-shaped structure forms a wrap-around limit on the grip component 41, reducing lateral swaying during use and enhancing operational safety; the integrated structure of the support body 421 and the second joint 422 has high strength, further improving the stability of the contact between the grip component 41 and the support member 42.

[0069] In the fifth embodiment of this application, please refer to Figure 13-16 The second joint is located outside the first joint. The second joint 422 also includes toothed or wavy ends 423 on the sheet-like structure formed by bending the two ends of the support body 421. The first joint 4112 also includes toothed or wavy ends 423 on the sheet-like structure formed by extending from the lower end of the gripping component 41. In this embodiment, the toothed or wavy ends 423 of the second joint 422 are disposed on the inner sidewall of the second joint 422, and the toothed or wavy ends 423 of the first joint 4112 are disposed on the outer sidewall of the first joint 4112. Through the cooperation of the toothed or wavy ends 423 on the opposing surfaces of the first joint 4112 and the second joint 422, the stability of the installation angle of the gripping component 41 on the support member 42 after the first joint 4112 and the second joint 422 abut against each other is further improved.

[0070] In an optional embodiment, the first connecting portion is located outside the second connecting portion. The second connecting portion 422 further includes toothed or wavy ends 423 on the sheet-like structure formed by bending the two ends of the support body 421. The first connecting portion 4112 also includes toothed or wavy ends 423 on the sheet-like structure formed by extending from the lower end of the gripping component 41. In this embodiment, the toothed or wavy ends 423 of the second connecting portion 422 are disposed on the outer side wall of the second connecting portion 422, and the toothed or wavy ends 423 of the first connecting portion 4112 are disposed on the inner side wall of the first connecting portion 4112. Through the cooperation of the toothed or wavy ends 423 on the opposing surfaces of the first connecting portion 4112 and the second connecting portion 422, the stability of the installation angle of the gripping component 41 on the support member 42 after the first connecting portion 4112 and the second connecting portion 422 abut against each other is further improved.

[0071] The advantages of providing gear teeth or wavy ends 423 on the first joint 4112 and the second joint 422 are as follows: First, during the operation of the water vehicle, the grip component 41 will be subjected to large axial or radial forces (such as torque during turning or reaction force generated by water flow impact). The first and second joints 422 can distribute the force to multiple contact points through the cooperation of gear teeth or wavy ends 423, which significantly improves the shear resistance of the joints. If the first joint 4112 and the second joint 422 are in planar contact, the first joint 4112 and the second joint 422 are fixed by friction alone. Under large loads, relative sliding is likely to occur (especially in humid environments, the relative friction between the first joint 4112 and the second joint 422 is easily reduced by water film), causing the grip component 41 to deviate from the angle on the support 42. Secondly, the engagement of the gear teeth or wavy end 423 between the first and second joints 422 can work synergistically with the squeezing force of the locking member 432. When the locking member 432 squeezes the joint through the cam 4321, the engagement of the gear teeth or wavy end 423 can convert the squeezing force into a stronger anti-separation force. Even a small locking force can lock the angle of the grip component 41 on the support member 42. This design reduces the force required for the operator to rotate the locking member 432 (reliable locking can be achieved without over-tightening), improves the convenience of human-machine interaction, and is especially suitable for scenarios where gloves may be worn or hands may be wet during the use of watercraft. Finally, the continuous vibration of the watercraft during use can easily cause slight relative sliding (fretting) between the first joint 4112 and the second joint 422 in the locked state. If the first joint 4112 and the second joint 422 are planar joints, this fretting will aggravate the wear of the first joint 4112 and the second joint 422, which will lead to an increase in the mating clearance in the long term and affect the fixing effect of the two. By setting gear teeth or wavy end 423 on the first and second joints 422, the slight relative displacement of the joints can be limited, reducing fretting wear from the root.

[0072] Furthermore, the first connecting portion 4112 is provided with a first limiting portion 4113, and the second connecting portion 422 is provided with a second limiting portion 424 that cooperates with the first limiting portion 4113, so as to limit the installation angle of the gripping component 41 on the support member 42 when the first connecting portion 4112 and the second connecting portion 422 cooperate.

[0073] In an alternative embodiment, see [reference] Figure 3 and Figure 6The second connecting portion 422 is located outside the first connecting portion 4112. The first limiting portion 4113 is a protrusion provided on the outer wall of the first connecting portion 4112, and the second limiting portion 424 is a snap-fit ​​hole provided on the second connecting portion 422. The hard limiting structure formed by the cooperation of the protrusion and the snap-fit ​​hole can limit the installation angle of the gripping component 41 on the support member 42. In this embodiment, there is one first limiting portion 4113 and two second limiting portions 424. One protrusion matches two snap-fit ​​holes to lock the position of the gripping component 41 when it is in the supporting and retracted positions. It should be noted that the installation angle of the gripping component 41 on the support member 42 can be determined by the position of the first limiting portion 4113 on the first connecting portion 4112 and the position of the second limiting portion 424 on the second connecting portion 422. In addition, multiple locking holes can be pre-set to match a single protrusion, providing discrete and clear positioning positions for the installation angle of the grip component 41 (e.g., one protrusion and locking hole position corresponds to each 15° or 30° rotation), so that the installation angle of the grip component 41 can adapt to different users (e.g., operators of different heights) and their operating habits (e.g., standing to operate a water vehicle or sitting to operate a water vehicle). In this embodiment, the installation angle of the grip component 41 on the support member 42 is limited by the cooperation between the protrusion and the locking hole. In the fourth embodiment, the installation angle of the grip component 41 on the support member 42 is limited by the friction between the first joint 4112 and the second joint 422. In the fifth embodiment, the installation angle of the grip component on the support member is limited by the wavy end 423 on the first joint 4112 and the second joint 422. Compared with the other two embodiments, limiting or adjusting the installation angle of the grip component 41 on the support member 42 by the cooperation between the protrusion and the locking hole makes the processing of parts more convenient and the adjustment process smoother. In this application, the second connecting part 422 is a thin sheet of stainless steel. During the rotation of the locking member 432 in the second direction, the first abutting surface 4322 and the contact surface 441 gradually disengage. There is a gap between the second abutting surface 4323 and the contact surface 441. At this time, since the locking member 432 releases the restriction on the installation angle locking state of the gripping component 41 on the support member 42, and there is a gap between the second abutting surface 4323 and the contact surface 441, the second connecting part 422 is given deformation space to disengage from the first connecting part 4112 (that is, without the locking force of the locking member 432, the second connecting part 422 will deform away from the first connecting part 4112 due to its material and thin sheet properties, thereby disengaging from the first connecting part 4112). This allows the protrusion on the first connecting part 4112 to disengage from the snap-fit ​​hole on the second connecting part 422, thereby facilitating the adjustment of the installation angle of the gripping component 41 on the support member 42.

[0074] When a watercraft is subjected to dynamic loads such as water flow impact and engine vibration, without the abutting pressure of the first joint 4112 and the second joint 422, the protrusion and the locking hole are prone to relative wobbling due to the gap. Over time, this may lead to wear of the protrusion and deformation of the locking hole (especially in a saltwater corrosive environment), eventually resulting in the loss of the limiting function. The locking constraint formed by the abutting pressure can ensure that the protrusion is always tightly fitted with the hole wall of the locking hole, eliminating the fit gap between the two. The lateral support of the hole wall on the protrusion resists the shear force generated by vibration, thus preventing the limiting structure from loosening at the source and solving the problem of limiting failure under dynamic loads. The engagement between the protrusion and the snap-fit ​​hole is a form-locking mechanism, while the contact between the first and second joints 422 is a force-locking mechanism, forming a double constraint. The form-locking mechanism (the protrusion snapping into the snap-fit ​​hole) directly restricts the relative rotation of the two through a mechanical structure, which is the core guarantee for limiting the installation angle of the gripping component 41 on the support 42. The force-locking mechanism enhances the stability of the form-locking mechanism through friction and pressure, preventing the form-locking mechanism from failing due to local wear (such as the protrusion becoming rounded). This double-safety design significantly improves the structural tolerance compared to a single form-locking or force-locking mechanism. The protrusion and the snap-fit ​​hole can be directly formed by machining the sidewalls of the first and second joints 422 (such as stamping or injection molding), eliminating the need for additional limiting accessories and simplifying the complexity of the structure. In addition, the contact between the first joint 4112 and the second joint 422 distributes the force on the protrusion and the snap-fit ​​hole to the overall structure of the joint (rather than concentrating it only on the protrusion itself), reducing the requirement for the individual strength of the protrusion (such as eliminating the need to excessively thicken the size of the protrusion).

[0075] In an optional embodiment, the first connecting portion 4112 is located outside the second connecting portion 422. Alternatively, a snap-fit ​​hole may be provided on the first connecting portion 4112 and a protrusion may be provided on the second connecting portion 422 to limit the installation angle of the gripping component 41 on the support member 42. The principle is the same as that of the ninth embodiment, and will not be described in detail here.

[0076] Furthermore, the pivot member 431 is provided with a flat portion 4315, and the gripping assembly 41 is provided with an installation channel 414 for one end of the pivot member 431 to pass through. The installation channel 414 is provided with a flat segment 4141 to fit the flat portion 4315.

[0077] In this application, taking the pivot member 431 corresponding to the second embodiment and the abutment member 44 provided on one side of the support member 42 as an example, the cooperation between the flat part 4315 and the flat section 4141 will be described. In this embodiment, the mounting channel 414 is provided with a flat section 4141 at one end near the locking member 432. When the pivot member 431 passes through the mounting channel 414, the flat part 4315 and the flat end in the mounting channel 414 are tightly engaged, which can rigidly restrict the circumferential rotation of the pivot member 431 in the mounting channel 414 (that is, restrict the relative rotation between the pivot member 431 and the gripping component 41), and avoid the pivot member 431 and the gripping component from disengaging after long-term use. The relative wear between 41 prevents the gripping component 41 from becoming loose, while also preventing the pivot 431 from slipping in the mounting channel 414 when the gripping component 41 rotates, thus affecting the rotation effect of the gripping component 41. The flat fit also prevents the pivot 431 from sliding axially in the mounting channel 414, ensuring that the squeezing force of the cam part 4321 can be accurately transmitted to the support 42 or the gripping component 41 when the locking part 432 rotates, preventing the loss or displacement of the squeezing force. The flat part 4315 and the flat part shape match the directional assembly characteristics, which can quickly achieve the axial positioning of the pivot 431 and the gripping component 41 during the installation process. It should be noted that when the contact surface 441 is provided on the support member 42 or the grip component 41, one end of the mounting channel 414 on the grip component 41 is a flat hole, and the support member 42 is provided with a corresponding round hole. When the pivot member 431 is inserted into the mounting channel 414, the round hole on the support member 42 will not affect the synchronous rotation of the pivot member 431 and the grip component 41.

[0078] Of course, a flat portion can also be provided on the pivot member 431 of the first embodiment. The corresponding structure and the technical effect that can be achieved are foreseeable. The mounting channel 414 is provided with a flat section on the side near the locking member 432 to ensure that the first pivot portion 4311 of the pivot member 431 can pass through the gripping component 41 and the support member 42.

[0079] Further, please refer to Figures 1-17 The gripping assembly 41 includes a rotating member 411, a gripping member 412, and a clamping structure 413. One end of the rotating member 411 is pivotally connected to the support member 42, and the other end of the rotating member 411 is provided with an opening. The mounting end of the gripping member 412 extends into the cavity of the rotating member 411 through the opening. The length of the gripping member 412 within the cavity of the rotating member 411 can be adjusted along the direction of the opening. The clamping structure 413 is used to fix the relative position of the gripping member 412 on the rotating member 411.

[0080] In this embodiment, the rotating component 411 is a hollow cavity. The lower end of the rotating component 411 is pivotally connected to the support component 42, and the upper end of the rotating component 411 is provided with an opening. The gripping component 412 extends into the rotating component 411 through the upper opening of the rotating component 411. The clamp structure 413 can fix the relative position of the gripping component 412 on the rotating component 411. The clamp assembly fixes the adjusted length of the gripping component 412, so that the gripping component 41 can adapt to the gripping habits of users of different heights (such as children and adults, standing and sitting postures), improving the comfort and practicality of use. The clamp structure 413 has a simple and reliable fixing method, and there is no loosening after adjustment, ensuring the stability of the gripping component 41 during operation. While the gripping component 41 is telescopically adjustable, it can also be folded and rotated around the pivot component 431 as an axis, enhancing the portability of the water vehicle and making it easy to store the water vehicle during transportation or when not in use.

[0081] Furthermore, the rotating member 411 extends outward from one end of the opening to form a pipe opening 4111, and the clamping structure 413 is sleeved on the outer periphery of the pipe opening 4111, with the lower end of the clamping structure 413 contacting the upper end face of the rotating member 411; a sleeve member 45 is also provided between the pipe opening 4111 and the gripping member 412, and the end of the sleeve member 45 extends outward to form a support portion 451 to support the sleeve member 45 on the pipe opening 4111.

[0082] In this application, the upper opening of the rotating member 411 extends outward to form a nozzle 4111. The rod of the gripping member 412 enters the hollow cavity of the rotating member 411 through the nozzle 4111. The clamping structure 413 includes a base 4131 and an adjusting part 4132 connected to the base 4131. The base 4131 is circular or elliptical. Preferably, in this embodiment, the base 4131 is elliptical, and the radial cross-sectional shape of the rod of the gripping member 412 is the same as the radial cross-sectional shape of the nozzle 4111. The base 4131 and the adjusting part 4132 are connected together. The shape of the section 4132 is adapted to the radial cross section of the nozzle 4111. The adjusting section 4132 is provided with a notch. The end face of the notch extends along the major axis of the elliptical ring to form two oppositely arranged connecting ears. The two connecting ears are tightened circumferentially by bolts and nuts (which is a common clamp locking method, which is the prior art) or by using a locking assembly similar to that in this application to drive the deformation of the adjusting section 4132. The base 4131 and the adjusting section 4132 are connected by an arc surface to avoid the deformation of the adjusting section 4132 from affecting the structure of the base 4131. The lower end of the base 4131 contacts the end face of the rotating part 411. On the one hand, it provides a horizontal reference for the clamp structure 413, ensuring that the central axis of the clamp structure 413 is coaxial with the axis of the pipe opening 4111 and the gripper 412. This avoids uneven distribution of the squeezing force on the pipe opening 4111 due to installation deviation, which affects the reliability of the clamp structure 413 locking. On the other hand, it can accurately limit the lowest position of the clamp structure 413 in the axial direction, ensuring that the squeezing action of the clamp structure 413 is concentrated in the effective mating section between the pipe opening 4111 and the sleeve 45 (i.e., the key area where the pipe opening 4111 needs to be tightened to clamp the gripper 412). If the axial position of the clamp structure 413 cannot be marked, it may exceed the effective length range of the pipe opening 4111, resulting in the inability to effectively clamp the gripper 412. Meanwhile, this axial reference ensures the consistency of the axial position of the clamp structure 413 during each installation or adjustment. This allows the operator to determine that the clamp structure 413 is in an effective working position simply by feeling the lower end of the clamp structure 413 against the upper surface of the rotating part 411, eliminating the need for additional positioning marks and improving operational convenience. The radial cross-section of the rod and the nozzle 4111 of the gripper 412 is elliptical rather than circular, preventing the gripper 412 from rotating circumferentially on the rotating part 411 during assembly. This facilitates quick installation and adjustment of the gripper 412 on the rotating part 411. The connecting lug of the adjusting part 4132 is located on one side of the long axis of the elliptical ring, increasing the adjusting lever arm and making the locking operation of the adjusting part 4132 easier.

[0083] In this embodiment, a plastic sleeve 45 is further provided between the nozzle 4111 and the gripper 412. The upper end of the sleeve 45 extends outward to form an annular flange (i.e., a support 451), and the lower end of the sleeve 45 extends into the nozzle 4111. The support 451 is placed on the end face of the nozzle 4111, stably supporting the sleeve 45 on the nozzle 4111. The inner diameter of the sleeve 45 is adapted to the outer diameter of the gripper 412, and the outer diameter of the sleeve 45 is adapted to the inner diameter of the nozzle 4111. In this application, the rod of the gripper 412 is made of carbon fiber. The sleeve 45 avoids direct contact between the tube opening 4111 and the rod of the gripper 412, reducing wear between them. On the other hand, it indirectly increases the relative friction between the tube opening 4111 and the rod of the gripper 412, improving the locking effect of the clamp structure 413 on the tube opening 4111 and the gripper 412. The support 451 ensures that the sleeve 45 will not slide axially during use, ensuring assembly accuracy. In addition, the versatility of the components can be improved by replacing the sleeve 45 with different thicknesses to adapt to grippers 412 of different sizes.

[0084] Furthermore, both the nozzle portion 4111 and the sleeve 45 are provided with U-shaped slots 452. In this application, the sidewalls of the nozzle portion 4111 and the sidewalls of the sleeve 45 are provided with axially open slots (i.e., U-shaped slots 452) along the axial direction. The number of U-shaped slots 452 is at least one, and the number of U-shaped slots 452 can be set according to requirements. In the embodiment of this application, the number of U-shaped slots 452 is one, and the depth of the U-shaped slots 452 on the nozzle portion 4111 and the sleeve 45 does not penetrate the length of the structure itself, thus preserving structural strength. The U-shaped groove 452 provides deformation space for the pipe opening 4111 and the sleeve 45. When the clamp structure 413 is tightened, both can shrink towards the center along the direction of the U-shaped groove 452, which enhances the locking effect of the clamp structure 413. The U-shaped groove 452 also reduces the machining accuracy requirements of the pipe opening 4111 and the sleeve 45, and can compensate for dimensional errors through deformation, thereby improving assembly convenience.

[0085] In summary, the folding mechanism for watercraft provided by this utility model includes:

[0086] The device includes a gripping assembly with a first engaging portion; a support member on which the gripping assembly is mounted, and a second engaging portion on which the gripping assembly engages with the first engaging portion to limit the installation angle of the gripping assembly on the support member; and a locking assembly for locking the gripping assembly onto the support member. Rotation of the locking assembly locks or releases the installation angle of the gripping assembly on the support member. When the locking assembly rotates in a first direction, it presses against the support member or the gripping assembly, causing them to abut against each other, thereby locking the engagement between the first engaging portion and the second engaging portion. When the locking assembly rotates in a second direction, the abutment between the support member and the gripping assembly is released, allowing the first engaging portion and the second engaging portion to move relative to each other.

[0087] This utility model relates to a folding mechanism for watercraft. The first connecting part on the grip component cooperates with the second connecting part on the support to limit the installation angle of the grip component on the support. By rotating the locking component, the relative relationship between the support and the grip component is changed to lock or unlock the installation angle, enabling the grip component to have a folding function. This solves the problems of large space occupation and easy collision during transportation and storage of traditional fixed control levers, significantly reducing the space occupied in the non-use state and improving portability.

[0088] It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of this utility model, and all such substitutions or modifications should fall within the protection scope of the appended claims.
