Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a handheld component and photographic auxiliary device for photographic assistance. Background Technology

[0002] With the popularization and development of photography technology, users have placed higher demands on the stability and convenience of shooting images, prompting the continuous innovation of various photography auxiliary equipment. Among them, camera shoulder mounts, tripods, and other auxiliary equipment occupy an important position in the market due to their respective advantages.

[0003] To meet the needs of diverse shooting scenarios, most of these devices are equipped with handheld components for photography auxiliary equipment, enabling functions such as angle adjustment and folding for storage. Taking the handheld component of a camera shoulder mount as an example, its arm and handle are connected by rotation, allowing users to adjust the handle angle according to their own body size, improving grip comfort and ease of operation. After use, it can also be folded for storage, making it easy to carry and store.

[0004] However, in the handheld components of related photography auxiliary equipment, the locking and unlocking structure is mostly a detachable dual-tooth disc structure with a locking mechanism. To unlock, one of the tooth discs needs to be loosened through the locking mechanism, rotated, and then locked again. The structure is complex and the operation is cumbersome, which affects the user experience. Utility Model Content

[0005] The main purpose of this utility model is to propose a handheld component for a photography auxiliary device, which aims to solve the technical problem that the locking and unlocking structure design of the current handheld components of photography auxiliary devices is complex and cumbersome to operate, affecting the user experience.

[0006] To achieve the above objectives, this utility model proposes a handheld component for a photography auxiliary device, which includes:

[0007] A connecting arm, one end of which is used to connect to the photographic auxiliary equipment, and the other end is configured with a rotatable connection structure;

[0008] The grip is strip-shaped and has an internal mounting cavity. One end of the grip is rotatably connected to the other end of the connecting arm.

[0009] A telescopic rod is slidably disposed within the mounting cavity. A positioning rod is sleeved on the free end of the telescopic rod. The positioning rod is offset from the rotation axis of the grip and the connecting arm and inserted into the other end of the connecting arm.

[0010] A locking mechanism includes an operating element for locking or unlocking the telescopic rod, the operating element being exposed outside the grip;

[0011] When the operating element is in the locked state, the telescopic rod is fixed, restricting the positioning rod from sliding the telescopic rod along its own axial direction to prevent the grip from rotating relative to the connecting arm; when the operating element is in the unlocked state, the telescopic rod is movable, allowing the positioning rod to slide the telescopic rod along its own axial direction to allow the grip to rotate relative to the connecting arm.

[0012] Optionally, the gripping member includes a connector and a gripping tube, one side of the connector is rotatably connected to the connecting arm, one end of the connector is sleeved with the gripping tube, and the connector is provided with a through hole for the telescopic rod to pass through.

[0013] Optionally, the other end of the connecting arm is provided with a connecting hole, and the handheld component of the photography auxiliary device further includes:

[0014] The connecting shaft, the gripping member and the connecting arm are rotatably connected to the connecting shaft through the connecting hole.

[0015] Optionally, the locking mechanism further includes:

[0016] The cylinder body is sleeved with the mounting cavity, and the cylinder body stores hydraulic oil. The telescopic rod includes a piston head, which is slidably connected to the cylinder body.

[0017] Optionally, the locking mechanism further includes:

[0018] A pressure relief component, located on one side of the piston head, includes a pressure relief switch and a pressure relief port connected to the pressure relief switch, and the pressure relief switch is connected to the operating component.

[0019] Optionally, the pressure relief component further includes a pressure relief chamber connected to the pressure relief switch.

[0020] Optionally, the free end of the telescopic rod is provided with a connecting sleeve, and the positioning rod is connected to the telescopic rod through the connecting sleeve.

[0021] Optionally, the connecting sleeve is configured with a strip-shaped hole, and the positioning rod passes through the strip-shaped hole.

[0022] Optionally, the gripper is provided with an arc-shaped limiting groove, the center of which coincides with the rotation center of the gripper;

[0023] The connecting arm is provided with a limiting hole that matches the arc-shaped limiting groove, and the positioning rod passes through the arc-shaped limiting groove and is inserted into the limiting hole.

[0024] This invention also proposes a photography aid device, which includes a handheld component of the photography aid device as described in the foregoing embodiments.

[0025] In use, the handheld component of this photographic aid device has several advantages. When unlocking is required, the telescopic rod is unlocked by manipulating the locking mechanism, releasing its fixation. This allows the positioning rod to extend or retract the telescopic rod, enabling the grip to rotate relative to the connecting arm, thus unlocking the handheld component. The user can then rotate the grip to adjust the angle. Conversely, when locking is required, the telescopic rod is locked by manipulating the locking mechanism, fixing it and preventing the positioning rod from extending or retracting. This prevents the grip from rotating relative to the connecting arm, thus locking the handheld component. Therefore, this handheld component, employing a combination of a positioning rod, a telescopic rod, and a locking mechanism, offers a simpler and more convenient locking and unlocking mechanism compared to traditional, complex locking and unlocking structures. Users only need to manipulate the telescopic rod to lock or unlock, easily achieving the locking and unlocking functions of the handheld component. This simple operation enhances the user experience.

[0034] Reference Figure 1 This embodiment of the invention provides a handheld component 100 for a photography auxiliary device. The photography auxiliary device may be a camera shoulder mount, a handheld gimbal, a camera handle, etc., and this embodiment does not limit the scope of the device. The handheld component 100 is used in the photography auxiliary device for the user to hold and operate the device. The number of handheld components 100 may be one or more, and this embodiment does not limit the scope of the device.

[0035] For example, the photography auxiliary device is a photography shoulder mount, with two handheld components 100. The two handheld components 100 are connected to the shoulder mount body of the photography shoulder mount. When the user carries the shoulder mount body, he holds the two handheld components 100 with both hands to achieve stable control of the photography shoulder mount, which is convenient for shooting from different angles and postures.

[0036] like Figure 1 As shown, the handheld component 100 of the photography assistance device includes:

[0037] Connecting arm 110, one end of which is used to connect to photographic auxiliary equipment, and the other end is constructed with a rotating connection structure;

[0038] The grip 120 is strip-shaped and has an internal mounting cavity 1201. One end of the grip 120 is rotatably connected to the other end of the connecting arm 110.

[0039] Telescopic rod 130 is slidably disposed in mounting cavity 1201. A positioning rod 10 is sleeved on the free end of telescopic rod 130. The positioning rod 10 is offset from the rotation axis Z of grip 120 and connecting arm 110 and inserted into the other end of connecting arm 110.

[0040] The locking mechanism 140 includes an operating element 141 for locking or unlocking the telescopic rod 130, the operating element 141 being exposed outside the grip 120;

[0041] When the operating element 141 is in the locked state, the telescopic rod 130 is fixed, restricting the positioning rod 10 from driving the telescopic rod 130 to slide along its own axial direction, thereby preventing the grip 120 from rotating relative to the connecting arm 110; when the operating element 141 is in the unlocked state, the telescopic rod 130 is movable, allowing the positioning rod 10 to drive the telescopic rod 130 to slide along its own axial direction, thereby allowing the grip 120 to rotate relative to the connecting arm 110.

[0042] In this embodiment, the handheld assembly 100 includes a connecting arm 110, a grip 120, a telescopic rod 130, and a locking mechanism 140. One end of the connecting arm 110 is used to connect to a photography auxiliary device (such as the shoulder support body of a photography shoulder carrier). The other end of the connecting arm 110 is provided with a rotating connection structure, which can be a shaft-hole mating structure. Specifically, the other end of the connecting arm 110 is provided with a shaft hole or a convex shaft, and the axis of the shaft hole or convex shaft is the rotation axis Z of the grip 120 and the connecting arm 110.

[0043] The grip 120 is strip-shaped and ergonomically designed for easy user grip. Its internal structure includes a mounting cavity 1201, which is a hollow structure extending along the length of the grip 120. One end of the grip 120 has a convex shaft or shaft hole that mates with the rotatable connection structure at the other end of the connecting arm 110, achieving rotatable connection with the other end of the connecting arm 110 through the engagement of the convex shaft and shaft hole.

[0044] The telescopic rod 130 is slidably disposed within the mounting cavity 1201 and can slide freely along the length of the mounting cavity 1201. A positioning rod 10 is sleeved on the free end of the telescopic rod 130. Specifically, the free end of the telescopic rod 130 and the positioning rod 130 can be connected by a sliding fit. For example, the free end of the telescopic rod 130 has an oblong hole, through which it is sleeved onto the positioning rod 10 for a sliding fit. The positioning rod 10 is offset from the rotation axis Z of the gripper 120 and the connecting arm 110 and inserted into the other end of the connecting arm 110. Specifically, the other end of the connecting arm 110 has a hole whose position is adapted to match the positioning rod 10. The positioning rod 10 is inserted into the hole to be fixedly mounted on the connecting arm 110.

[0045] The locking mechanism 140 includes an operating element 141 for locking or unlocking the telescopic rod 130. The operating element 141 is exposed outside the grip 120 for easy user operation. The operating element 141 can be in the form of a knob, lever, or similar mechanism. The locking mechanism 140 may also include locking components that cooperate with the operating element 141, such as friction plates or locking pins. When the operating element 141 is in the locked state, the locking components fix the telescopic rod 130; when the operating element 141 is in the unlocked state, the locking components release the telescopic rod 130, allowing it to move.

[0046] For example, the operating element 141 is a knob, located on the side of the grip 120 and exposed therefrom. The locking mechanism 140 has a screw connected to the knob, one end of which is connected to a friction plate. When the knob is rotated to lock the operating element 141, the screw pushes the friction plate to press firmly against the telescopic rod 130, fixing the telescopic rod 130 through friction. When the knob is rotated in the opposite direction to unlock the operating element 141, the friction plate separates from the telescopic rod 130, allowing the telescopic rod 130 to slide freely. Alternatively, the operating element 141 is a pull button, located on the side of the grip 120 and exposed therefrom. The locking mechanism 140 has a positioning rod 10 connected to the pull button, and the positioning rod 10 is fitted with a spring for resetting it. The telescopic rod 130 has several positioning holes arranged sequentially along its length. When the release button locks the operating element 141, the positioning rod 10 is inserted into a positioning hole in the telescopic rod 130, fixing the telescopic rod 130 in place through positioning and the elastic force of the spring. When the release button unlocks the operating element 141, the positioning rod 10 disengages from the positioning hole in the telescopic rod 130, allowing the telescopic rod 130 to slide freely. Besides the above example, the locking mechanism 140 can also adopt other structural forms, which are not limited in this embodiment.

[0047] When the operating member 141 is in the locked state, the telescopic rod 130 is fixed, that is, the telescopic rod 130 is fixed relative to the grip 120 and cannot be extended or retracted. When the grip 120 is rotated, since the telescopic rod 130 is in a fixed and non-extendable state, the positioning rod 10 cannot drive the telescopic rod 130 to slide along its own axial direction, thereby achieving the effect of rotation being blocked. Therefore, the grip 120 can be prevented from rotating relative to the connecting arm 110, that is, the grip 120 is in a locked state and its angle cannot be adjusted.

[0048] When the operating member 141 is in the unlocked state, the telescopic rod 130 is movable, that is, the telescopic rod 130 can move relative to the grip 120. When the grip 120 is rotated, since the telescopic rod 130 is in a movable and telescopic state, the positioning rod 10 can drive the telescopic rod 130 to slide along its own axial direction, so that it can rotate normally. Therefore, the grip 120 is allowed to rotate relative to the connecting arm 110, that is, the grip 120 is in the unlocked state and its angle is adjustable.

[0049] In this embodiment, the handheld component 100 of the photography auxiliary device adopts a combination of a positioning rod 10, a telescopic rod 130, and a locking mechanism. Compared with the traditional complex locking and unlocking structure, it has fewer parts and a simpler structural layout. Users only need to lock or unlock the telescopic rod 130 by operating the control component 141 to easily realize the locking and unlocking functions of the handheld component 100 of the photography auxiliary device. The operation is simple and helps to improve the user experience.

[0050] The handheld component 100 of the photography auxiliary device in this embodiment can be widely used in various photography auxiliary devices, such as photography shoulder carriers and support frames. It is highly versatile and adaptable to a variety of different specifications and types of photography equipment, which can meet the usage needs of different users in diverse shooting scenarios, and further enhance the practicality and market competitiveness of photography auxiliary devices.

[0051] In some embodiments, refer to Figure 2 The grip 120 includes a connector 121 and a grip tube 122. One side of the connector 121 is rotatably connected to the connecting arm 110, and one end of the connector 121 is sleeved with the grip tube 122. The connector 121 is provided with a through hole 1211 through which the telescopic rod 130 passes.

[0052] In this embodiment, the grip 120 adopts a split structure design, specifically including a connector 121 and a grip tube 122. The connector 121 serves as the connection medium between the grip 120 and the connecting arm 110. One side of the connector 121 and the end of the connecting arm 110 away from the photography auxiliary device are rotated together through a rotating connection structure. This rotating connection structure can adopt the shaft-hole fit as described above (for example, the connector 121 is provided with a convex shaft, and the connecting arm 110 is provided with a shaft hole at the corresponding position) to ensure the smoothness and stability of the rotation of the grip 120.

[0053] The end of connector 121 furthest from the rotating connection side is connected to grip tube 122 via a sleeve connection, which can be achieved through threaded connection or snap-fit ​​connection to ensure the stability of the connection. Grip tube 122 is a hollow strip structure with an internal cavity forming a mounting cavity 1201 for sliding telescopic rod 130. The outer surface of grip tube 122 can be ergonomically designed as an arc surface or have anti-slip texture to further improve the user's grip comfort and anti-slip effect. Furthermore, the connector 121 has a through hole 1211 along its length. The diameter of the through hole 1211 is adapted to the outer diameter of the telescopic rod 130, and the axis of the through hole 1211 is collinear with the axis of the mounting cavity 1201 of the grip tube 122. This allows the end of the telescopic rod 130 away from the positioning rod 10 to pass through the through hole 1211 of the connector 121 and extend into the mounting cavity 1201 of the grip tube 122, achieving a sliding fit between the telescopic rod 130 and the gripper 120. When the gripper 120 rotates relative to the connecting arm 110, the telescopic rod 130 can slide stably along the collinear direction of the through hole 1211 and the mounting cavity 1201.

[0054] In some embodiments, refer to Figure 2 The other end of the connecting arm 110 is provided with a connecting hole 1101, and the handheld component 100 of the photography auxiliary device also includes:

[0055] The connecting shaft 150, the gripping member 120 and the connecting arm 110 are rotatably connected to the connecting shaft 150 through the connecting hole 1101.

[0056] In this embodiment, a connecting hole 1101 is provided at the end of the connecting arm 110 away from the photography auxiliary device. The connecting hole 1101 is provided through the axis perpendicular to the length direction of the connecting arm 110, and its diameter is adapted to the outer diameter of the connecting shaft 150 to form a precise fit.

[0057] Correspondingly, the handheld component 100 of the photography auxiliary device also includes a connecting shaft 150. This connecting shaft 150 has a cylindrical structure and can be made of high-strength metals (such as stainless steel or aluminum alloy) to ensure sufficient structural strength and wear resistance. Specifically, the connecting shaft 150 is positioned corresponding to the connecting hole 1101 of the connecting arm 110 on the grip 120 (as described above with the connector 121). The connecting shaft 150 passes through the connecting hole 1101 of the connecting arm 110, forming a rotating connection between the grip 120 and the connecting arm 110. The connecting shaft 150 and the connecting hole 1101 are fitted with a clearance fit, with the clearance controlled within a preset range. This ensures smooth rotation of the grip 120 relative to the connecting arm 110 while preventing wobbling due to excessive clearance, thus ensuring rotational accuracy.

[0058] The connecting hole 1101 and connecting shaft 150 used in this embodiment have a simple structure and are easy to standardize in size, making them convenient for mass production. During assembly, the connecting shaft 150 only needs to be passed through the corresponding hole for installation, which is simple to operate, reduces production and assembly costs, and improves production efficiency.

[0059] In some embodiments, refer to Figure 2 and Figure 3 The locking mechanism 140 also includes:

[0060] The cylinder body 142 is sleeved with the mounting cavity 1201. The cylinder body 142 stores hydraulic oil. The telescopic rod 130 includes a piston head 131, which is slidably connected to the cylinder body 142.

[0061] In this embodiment, the cylinder body 142 has an overall columnar structure, and its outer contour is adapted to the inner wall of the mounting cavity 1201 of the grip 120. It can be fixedly sleeved with the mounting cavity 1201 by means such as interference fit, snap connection or threaded connection to ensure the positional stability of the cylinder body 142 in the mounting cavity 1201.

[0062] The telescopic rod 130 can be regarded as the piston rod of the hydraulic cylinder formed with the cylinder body 142. The other end of the telescopic rod 130 opposite to its free end has a piston head 131. The piston head 131 is a disc-shaped structure adapted to the inner wall of the cylinder body 142. Its edge is embedded with an elastic sealing ring, which not only ensures the tight fit between the piston head 131 and the inner wall of the cylinder body 142, but also reduces the frictional resistance during sliding.

[0063] In some embodiments, refer to Figure 2 and Figure 3 The locking mechanism 140 also includes:

[0064] The pressure relief component 143 is located on one side of the piston head 131 and includes a pressure relief switch 1431 and a pressure relief hole 1432 connected to the pressure relief switch 1431. The pressure relief switch 1431 is connected to the operating component 141.

[0065] In this embodiment, the pressure relief hole 1432 is a through hole 1211 that extends through the piston head 131 along its axial direction. Its diameter is smaller than the diameter of the inner cavity of the cylinder 142, and it is used to connect the inner cavity of the cylinder 142 with other cavities (such as the pressure relief cavity 1433 in the subsequent embodiment). The pressure relief switch 1431 can be a switch valve for opening or closing the pressure relief hole 1432. It has a valve core 14311 and a return spring 14312 acting on the valve core 14311. The valve core 14311 of the pressure relief switch 1431 is mechanically connected to the operating member 141 through the valve stem to form a linkage structure.

[0066] The specific work process is as follows:

[0067] When the operating element 141 is in the locked state, it is not actively operated by the user. At this time, the valve core 14311 of the pressure relief switch 1431 is not subjected to additional external force and is in the closed position under the elastic force of the return spring 14312, thus closing the pressure relief hole 1432. Since the pressure relief hole 1432 is closed, the hydraulic oil in the inner cavity of the cylinder 142 cannot flow through the pressure relief hole 1432, and the hydraulic oil in the entire cylinder 142 forms a closed rigid space. Based on the incompressible properties of hydraulic oil, the piston head 131 is firmly constrained by the hydraulic oil and cannot slide along the axial direction of the cylinder 142, thereby keeping the telescopic rod 130 in a fixed state. The rotation of the gripper 120 relative to the connecting arm 110 is completely restricted, and its angle is stably locked.

[0068] When the operating element 141 is switched to the unlocked state, the user applies an operating force (such as pressing or pulling) to the operating element 141. This force is transmitted to the valve core 14311 of the pressure relief switch 1431 through the mechanical transmission structure. Under the pressure of the operating element 141, the valve core 14311 of the pressure relief switch 1431 overcomes the elastic force of the return spring 14312 and is in the open position, thereby opening the pressure relief port 1432. At this time, the hydraulic oil in the inner cavity of the cylinder 142 can flow into other cavities (such as the pressure relief chamber 1433) through the pressure relief port 1432, realizing the pressure relief of the hydraulic system. In this state, if the grip 120 is subjected to a rotational external force (such as the force when the user adjusts the angle), the positioning rod 10 will drive the telescopic rod 130 to produce axial movement, and the piston head 131 will slide along the cylinder 142. The hydraulic oil flows smoothly through the pressure relief port 1432 to adapt to the volume change, thereby allowing the grip 120 to rotate freely relative to the connecting arm 110, realizing angle adjustment.

[0069] In the locked state, the elastic force of the return spring 14312 ensures that the pressure relief hole 1432 remains closed. Combined with the incompressibility of the hydraulic oil, this forms a passive rigid lock, maintaining the stability of the grip 120 angle without requiring continuous application of force from the user. Even under complex conditions such as vibration and impact, it effectively prevents accidental rotation, significantly improving locking reliability. Furthermore, in the unlocked state, the flow of hydraulic oil through the pressure relief hole 1432 creates natural damping. Its flow rate is controlled by parameters such as the diameter of the pressure relief hole 1432 and the viscosity of the hydraulic oil, preventing rapid sliding of the telescopic rod 130 due to sudden changes in external force. This ensures that the angle change of the grip 120 remains stable and controllable, reducing interference with shooting operations. Simultaneously, this damping property buffers the impact force during rotation, reducing vibration in the user's hand and improving comfort during extended operation.

[0070] In some embodiments, refer to Figure 2 and Figure 3The pressure relief component 143 also includes a pressure relief chamber 1433 connected to the pressure relief switch 1431. In this embodiment, the pressure relief chamber 1433 can be a closed cavity independent of the inner cavity of the cylinder body 142, and can be integrated into the other end of the cylinder body 142 away from the end extending from the telescopic rod 130. It forms selective communication with the inner cavity of the cylinder body 142 (specifically the oil chamber on the side of the piston head 131) through the pressure relief hole 1432.

[0071] Specifically, one end of the pressure relief chamber 1433 is connected to the inner cavity of the cylinder body 142 through the pressure relief hole 1432, while the other end is a closed structure. When the pressure relief switch 1431's valve core 14311 closes the pressure relief hole 1432, it blocks the connection between the pressure relief chamber 1433 and the inner cavity of the cylinder body 142; when open, the valve core 14311 moves to fully open the pressure relief hole 1432, allowing hydraulic oil in the inner cavity of the cylinder body 142 to flow into the pressure relief chamber 1433 through the pressure relief hole 1432, or to flow back from the pressure relief chamber 1433 to the inner cavity of the cylinder body 142 when the piston head 131 moves in the opposite direction, forming a complete hydraulic circulation path. The pressure relief chamber 1433 is equipped with a pressure relief piston 14331 that slides within it, allowing the piston 14331 to slide within the pressure relief chamber 1433 as hydraulic oil flows in or out.

[0072] The working process of this structure is coordinated as follows:

[0073] When the operating element 141 is in the locked state, the valve core 14311 of the pressure relief switch 1431 closes the pressure relief hole 1432 under the action of the return spring 14312, blocking the passage between the inner cavity of the cylinder 142 and the pressure relief chamber 1433. At this time, the hydraulic oil in the cylinder 142 is confined within the closed space, the piston head 131 is rigidly constrained and cannot move, the telescopic rod 130 remains fixed, and the angle of the gripper 120 is locked. Since the pressure relief chamber 1433 does not participate in the flow, the hydraulic oil inside it (if pre-filled) is in a static state, which does not affect the locking stability.

[0074] When the operating element 141 is switched to the unlocked state, the valve core 14311 of the pressure relief switch 1431 opens the pressure relief hole 1432, and the inner cavity of the cylinder 142 is connected to the pressure relief chamber 1433. When the user rotates the grip 120, the positioning rod 10 drives the telescopic rod 130 to make the piston head 131 slide along the cylinder 142. The hydraulic oil in the inner cavity of the cylinder 142 is squeezed and flows into the pressure relief chamber 1433 through the pressure relief hole 1432 (or flows in the opposite direction). If the telescopic rod 130 extends outward and the piston head 131 moves towards the connecting arm 110, the inner cavity volume of the cylinder 142 increases, and the hydraulic oil flows back from the pressure relief chamber 1433 to the inner cavity of the cylinder 142 through the pressure relief hole 1432. If the telescopic rod 130 retracts and the piston head 131 moves away from the connecting arm 110, the inner cavity volume of the cylinder 142 decreases, and the hydraulic oil flows from the inner cavity of the cylinder 142 into the pressure relief chamber 1433 through the pressure relief hole 1432.

[0075] In some embodiments, refer to Figures 1 to 3 A connecting sleeve 132 is provided at the free end of the telescopic rod 130, and the positioning rod 10 is connected to the telescopic rod 130 through the connecting sleeve 132. Specifically, the connecting sleeve 132 is located at the free end of the telescopic rod 130 and is connected to or integrally formed with the telescopic rod 130. The connecting sleeve 132 is sleeved on the positioning rod 10, thereby realizing the connection between the telescopic rod 130 and the positioning rod 10.

[0076] When the operating component 141 is in the locked state, the telescopic rod 130 is fixed, that is, the telescopic rod 130 is fixed relative to the grip 120 and cannot be extended or retracted. When the grip 120 is rotated, since the telescopic rod 130 is in a fixed and non-extendable state, the relative position of its connecting sleeve 132 and the positioning rod 10 is fixed. The positioning rod 10 cannot drive the telescopic rod 130 to slide through the connecting sleeve 132, thereby achieving the effect of rotation being blocked. The grip 120 is locked and the angle cannot be adjusted.

[0077] When the operating component 141 is in the unlocked state, the telescopic rod 130 is movable, that is, the telescopic rod 130 can move relative to the grip 120. When the grip 120 is rotated, since the telescopic rod 130 is in a movable and telescopic state, the relative position of the positioning rod 10 and the connecting sleeve 132 can change. The positioning rod 10 can then drive the telescopic rod 130 to slide through the connecting sleeve 132, so that it can rotate normally. The grip 120 is unlocked and the angle is adjustable.

[0078] In this embodiment, the telescopic rod 130 and the positioning rod 10 are slidably connected through the connecting sleeve 132, which not only ensures the stability of force transmission between the two, but also meets the motion requirements of the grip 120 when rotating through the sliding cooperation, making the switching logic of the locking and unlocking states clear and the action reliable, and providing a structural basis for the angle adjustment of the handheld component 100.

[0079] In some embodiments, refer to Figures 1 to 3 The connecting sleeve 132 has a slotted hole 1321 through which the positioning rod 10 passes. The slotted hole 1321 extends along the length of the connecting sleeve 132 or at a predetermined angle (e.g., 90°) to the axial direction of the telescopic rod 130, forming a guide channel for the positioning rod 10. The positioning rod 10 passes through the slotted hole 1321, and its outer circumferential surface slides against the inner wall of the slotted hole 1321, allowing the connecting sleeve 132 to slide relative to the positioning rod 10 along the length of the slotted hole 1321.

[0080] When the operating component 141 is in the locked state, the telescopic rod 130 is fixed, and the connecting sleeve 132 remains stationary with the telescopic rod 130. At this time, the position of the positioning rod 10 within the slotted hole 1321 is fixed. Since the length direction of the slotted hole 1321 is adapted to the telescopic direction of the telescopic rod 130, the positioning rod 10 forms a rigid abutment with the side wall of the slotted hole 1321, hindering the displacement tendency of the connecting sleeve 132 caused by the rotation of the gripper 120. Consequently, the constraint force is transmitted to the telescopic rod 130 through the connecting sleeve 132, ultimately preventing the gripper 120 from rotating relative to the connecting arm 110, thus achieving angle locking.

[0081] When the operating element 141 is in the unlocked state, the telescopic rod 130 can extend and retract freely. When the grip 120 rotates, it drives the connecting sleeve 132 to move synchronously. Since the positioning rod 10 is fixed to the connecting arm 110 and deviates from the rotation axis Z, the rotation of the connecting sleeve 132 will cause the positioning rod 10 to slide relative to it along the length direction of the slot 1321 (the sliding distance varies with the rotation angle). At the same time, the guiding effect of the slot 1321 ensures that this sliding process is smooth and without jamming. The sliding of the positioning rod 10 pushes the connecting sleeve 132 through the side wall of the slot 1321, causing the telescopic rod 130 to extend and retract along its axial direction, thereby releasing the rotation constraint of the grip 120 and realizing angle adjustment.

[0082] In some embodiments, refer to Figure 1 and Figure 2 The grip 120 has an arc-shaped limiting groove 1202, the center of which coincides with the rotation center of the grip 120.

[0083] The connecting arm 110 is provided with a limiting hole 1102 that cooperates with the arc-shaped limiting groove 1202, and the positioning rod 10 passes through the arc-shaped limiting groove 1202 and is inserted into the limiting hole 1102.

[0084] When the operating component 141 is in the unlocked state, and the grip 120 can rotate relative to the connecting arm 110, since the center of the arc-shaped limiting groove 1202 coincides with the rotation center, the positioning rod 10 will slide relative to the grip 120 along an arc-shaped path within the arc-shaped limiting groove 1202 as the grip 120 rotates. At this time, the arc-shaped limiting groove 1202 provides precise guidance for the positioning rod 10, ensuring that the rotation trajectory of the grip 120 always revolves around the preset rotation center, avoiding deviation; at the same time, when the positioning rod 10 slides relative to the stop at either end of the arc-shaped limiting groove 1202, the stop will rigidly abut against the positioning rod 10, preventing the grip 120 from continuing to rotate in that direction, thereby limiting the angle adjustment range of the grip 120 to the arc range corresponding to the arc of the arc-shaped limiting groove 1202.

[0085] In this embodiment, the arc-shaped limiting groove 1202 mechanically limits the sliding stroke of the positioning rod 10 through the stop portions at both ends, thereby precisely limiting the maximum rotation angle of the grip 120 and preventing excessive rotation due to user error.
