[0048] Referring to Figures 1 to 5 The utility model provides a photographic equipment connecting handle, include:

[0049] Handle body 1 is used for connecting external photographic equipment;

[0050] Swing arm 2, one end of swing arm 2 is rotatably connected with one end of handle body 1, and handle body 1 can rotate around swing arm 2, and the other end of swing arm 2 is provided with a rotating part 21;

[0051] First locking member 3, first locking member 3 is connected with swing arm 2 and handle body 1, and is used to configure swing arm 2 and handle body 1 as relative fixed or relative movable state;

[0052] The second locking member 4 is connected to another external photographic equipment at one end and connected to the rotating part 21 at the other end. The second locking member 4 is used to lock or separate the rotating part 21, so as to fix the rotating arm 2 relative to the second locking member 4 or make the rotating arm 2 rotate horizontally around the second locking member 4.

[0053] In this embodiment, the photographic equipment connecting handle realizes multi-directional angle adjustment based on the rotating connection and locking mechanism. Through the rotating connection between the rotating arm 2 and the handle body 1, the control of the relative state of the rotating arm 2 and the handle body 1 by the first locking member 3, and the connection mode of the second locking member 4 and the rotating arm 2, the flexible adjustment and fixation of the angle of the photographic equipment in the vertical direction and the horizontal direction are realized by the cooperation between the components. Specifically:

[0054] The handle body 1 and the rotating arm 2 are connected through a rotating connection to form a hinge-like structure, allowing the handle body 1 to rotate around the rotating arm 2 in a vertical plane. The first locking member 3 is used to control the degree of freedom of the rotation of the handle body 1 around the rotating arm 2. When the first locking member 3 is in an active state, the friction between the handle body 1 and the rotating arm 2 is small or there is no contact, and the handle body 1 can rotate around the rotating arm 2 under the action of an external force (such as manual adjustment by the photographer), realizing the angle change of the photographic equipment in the vertical direction. When the first locking member 3 is switched to a fixed state, the rotation of the handle body 1 is limited by increasing the friction between the handle body 1 and the rotating arm 2 or forming a mechanical locking structure, thereby fixing the photographic equipment at a specific vertical angle. In some embodiments, the first locking member 3 can be a locking knob, a buckle or other components that can fix the rotating arm 2 and the handle body 1, which are only exemplary and not limited.

[0055] The other end of the rotating arm 2 is provided with a rotating part 21, and the second locking member 4 is connected to the rotating part 21. For example, the second locking member 4 and the rotating part 21 can be connected by screw threads. In some embodiments, the other end of the second locking member 4 can be connected to photographic equipment such as a tripod for fixing the position of the camera or video camera, or other photographic equipment as required, which are only exemplary.

[0056] The rotating adjustment process of the photographic equipment connecting handle of the present application can be divided into the following two kinds:

[0057] Vertical direction rotation adjustment: when the angle of the photographic equipment in the vertical direction needs to be adjusted, first operate the first locking member 3 according to the actual situation, so that the handle body 1 and the rotating arm 2 are set to a relative active state, so that the handle body 1 can rotate around the rotating arm 2 in the vertical direction. At this time, the photographer can manually rotate the handle body 1 around the rotating arm 2 in the vertical plane to the appropriate angle according to the shooting needs, for example, when shooting high-angle low-angle or low-angle overhead shot, the camera can be flexibly adjusted. After adjustment, operate the first locking member 3 again, and set the handle body 1 and the rotating arm 2 to a relative fixed state, so as to lock the relative position between the handle body 1 and the rotating arm 2, and ensure that the photographic equipment remains stable in the vertical direction and does not change the shooting angle due to accidental collision or shaking.

[0058] Horizontal direction rotation adjustment: if the angle in the horizontal direction needs to be adjusted, first loosen the second locking member 4 from the rotating part 21 (i.e. in a separated state), so that the rotating arm 2 can freely rotate around the second locking member 4 in the horizontal direction. The photographer can rotate the rotating arm 2 to the required angle according to the shooting scene, such as when shooting a panoramic view, and drive the photographic equipment to rotate in the horizontal direction. When the horizontal angle is adjusted to the right position, reconnect and lock the second locking member 4 to the rotating part 21, so that the rotating arm 2 and the second locking member 4 are again relatively fixed, ensuring the stability of the photographic equipment in the horizontal direction and avoiding unnecessary displacement during shooting.

[0059] The photographic equipment connection handle with the above structure achieves the following effects:

[0060] First, flexible multi-angle shooting: compared with the fixed connection handle in the prior art, the present application realizes free angle adjustment of the photographic equipment in the vertical and horizontal directions.

[0061] Second, improve shooting efficiency: during shooting, the angle can be conveniently switched and adjusted in two directions, without the need to disassemble or use other complex tools to change the shooting angle as in the traditional connection handle, saving a lot of time and effort.

[0062] Third, enhance stability and reliability: through the effective locking of the relative positions of the components by the first locking member 3 and the second locking member 4, the stability of the photographic equipment during shooting can be ensured after the angle is adjusted. Even in some more complex or bumpy shooting environments, such as when shooting outdoor scenery in a light wind or shooting on a moving platform, the picture blur or shooting errors caused by equipment shaking can be effectively reduced, improving the reliability of shooting.

[0063] In summary, the photographic equipment connecting handle of the present application sets the handle body 1 as the basic part of connecting the photographic equipment, one end of the rotating arm 2 is rotationally connected with the handle body 1, and the rotating arm 2 and the handle body 1 are configured to be relatively fixed or relatively movable by the first locking member 3, so that the free angle adjustment of the photographic equipment in the vertical direction is realized; the other end of the rotating arm 2 is provided with a rotating part 21, one end of the second locking member 4 is connected with the photographic equipment, and the other end is connected with the rotating part 21, and by using the separable and locking characteristics, the free angle adjustment of the photographic equipment in the horizontal direction is realized. Compared with the fixed connecting handle in the prior art, the photographic equipment can realize multi-angle flexible shooting, and the use convenience is higher.

[0064] Please continue to refer to Figures 1 to 3 In some embodiments, the handle body 1 of the present application is in a strip shape, comprising a holding section 101 and a connecting section 102, the connecting section 102 is located at one end of the holding section 101 and is used to connect with the rotating arm 2; the holding section 101 is composed of a first side wall 1011, a second side wall 1012, a third side wall 1013 and a fourth side wall 1014 which are connected in sequence, the first side wall 1011 and the third side wall 1013 are oppositely arranged, and the second side wall 1012 and the fourth side wall 1014 are oppositely arranged.

[0065] Among the first side wall 1011, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014, at least one is provided with a connecting structure 103 for connecting external photographic equipment.

[0066] In the present embodiment, the handle body 1 is set to a strip shape based on ergonomics and practicality. The strip shape is convenient for hand holding and carrying operation, and the photographer can hold the handle more naturally, and this shape also has advantages in space utilization, which is convenient for setting different connecting structures 103 on each side wall, and avoids mutual interference between the connecting structures 103.

[0067] The holding section 101 and the connecting section 102 can be an integrally formed structure, or a structure composed of two independent parts, which is only exemplarily described here.

[0068] Various photographic equipment will be used in the photographic process, and the interface types of these equipment are various. Multiple connecting structures 103 are set to make the handle compatible with as many photographic equipment as possible, thereby improving the versatility of the handle. Specifically:

[0069] The holding section 101 is formed by the first side wall 1011, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014 in sequence, and the first side wall 1011, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014 can be provided with a connecting structure 103 for connecting external photographic equipment, which can include docking structures such as threaded holes, pin holes and quick couplings, including but not limited to:

[0070] The screw interface product of each specification, the screw positioning pin product of each specification, the Aley positioning pin product of each specification can be installed and compatible; the pipe product with a diameter of ≤16mm can be connected; the cold shoe interface product or other expansion devices can be connected.

[0071] Preferably, the first side wall 1011, the second side wall 1012 and the third side wall 1013 are provided with the connecting structure 103, and the fourth side wall 1014 can be provided with silica gel, which is convenient for a hand to hold.

[0072] Please continue to refer to Figures 1 to 5 In some embodiments, the connecting section 102 is provided with a first through hole 1021, and the first locking member 3 includes:

[0073] The adjusting knob 31 is provided with a connecting rod 32 at one end, the connecting rod 32 passes through the first through hole 1021 and is connected with the rotating arm 2, and the adjusting knob 31 abuts against one side of the connecting section 102;

[0074] The adjusting knob 31 is used to drive the connecting rod 32 to rotate, so as to drive the rotating arm 2 to move towards or away from the handle body 1, so that the rotating arm 2 abuts against or separates from the handle body 1.

[0075] In the embodiment, the first locking member 3 is mainly based on the principle of threaded transmission and rotary drive, and the connecting rod 32 is driven to rotate by the adjusting knob 31, and one end of the connecting rod 32 is threadedly connected with the rotating arm 2, that is, the connecting rod 32 can be provided with external threads, and the rotating arm 2 is provided with an internal threaded hole matched with the external threads of the connecting rod 32, according to the threaded transmission principle, when the connecting rod 32 rotates, the rotating arm 2 will produce linear motion relative to the handle body 1. The adjusting knob 31 serves as a driving part to provide power for the rotation of the connecting rod 32, thereby realizing the control of the position of the rotating arm 2, so that the rotating arm 2 abuts against or separates from the handle body 1.

[0076] The working process of the first locking member 3 proposed in the application can be divided into the following two kinds:

[0077] Locking process (make the rotating arm 2 abut against the handle body 1):

[0078] When it is needed to lock the rotating arm 2 and the handle body 1 to fix the angle of the photographic equipment in the vertical direction, the adjusting knob 31 is operated. For example, the adjusting knob 31 is manually rotated to drive the connecting rod 32 to rotate. Since the connecting rod 32 is threadedly connected with the rotating arm 2, the rotating arm 2 is moved to the handle body 1 along the axial direction of the connecting rod 32 under the rotation of the connecting rod 32. With the movement of the rotating arm 2, the rotating arm 2 finally abuts against the handle body 1, at this time, the adjusting knob 31 can abut against the first side wall 1011, at this time, since the rotating arm 2 and the handle body 1 abut against each other, the friction between the rotating arm 2 and the handle body 1 is increased, the rotation of the handle body 1 around the rotating arm 2 is limited, and thus the locking of the angle of the photographic equipment in the vertical direction is realized.

[0079] Unlocking process (separating the rotating arm 2 from the handle body 1) :

[0080] When it is needed to adjust the angle of the photographic equipment in the vertical direction, the adjusting knob 31 is reversely operated. For example, the adjusting knob 31 is reversely rotated to drive the connecting rod 32 to reversely rotate. According to the reverse motion principle of the threaded transmission, the rotating arm 2 is moved away from the handle body 1 along the axial direction of the connecting rod 32, so that a gap is formed between the rotating arm 2 and the handle body 1 and the friction therebetween is reduced. In this way, the handle body 1 can freely rotate around the rotating arm 2, and the adjustment of the angle of the photographic equipment in the vertical direction is realized.

[0081] In some embodiments, the rotating arm 2 and the handle body 1 can directly abut against each other or indirectly abut against each other through friction plates, meshing toothed discs or other connecting elements, which are only exemplarily described herein.

[0082] The first locking member 3 with the above structure is arranged in the application, the quick locking and unlocking of the rotating arm 2 and the handle body 1 are realized, the rotating arm 2 and the handle body 1 are in the relatively movable state and the relatively fixed state, and the operation is convenient.

[0083] Reference Figures 4 to 8 In some embodiments, the photographic equipment connecting handle further comprises a first toothed disc 5 and a second toothed disc 6 matched with the first toothed disc 5, the first toothed disc 5 is arranged on the side of the connecting section 102 away from the adjusting knob, and the second toothed disc 6 is arranged on the rotating arm 2.

[0084] In the embodiment, the first toothed disc 5 and the second toothed disc 6 both have teeth with specific shapes and arrangements. When the second toothed disc 6 abuts against the first toothed disc 5, the teeth of the two toothed discs are meshed with each other. Since the shapes of the teeth and the meshing relationship, when the handle body 1 rotates around the rotating arm 2 in the vertical direction, the handle body 1 is blocked by the teeth. Since the side surfaces of the teeth abut against each other, the handle body 1 needs to overcome the large friction between the teeth and the mechanical blocking force of the teeth to rotate, so that the rotation of the handle body 1 relative to the rotating arm 2 in the vertical direction is effectively prevented, and the angle is fixed.

[0085] When the second toothed disc 6 is separated from the first toothed disc 5, the meshing and blocking relationship between the teeth is no longer present, and the handle body 1 is no longer limited by the toothed disc when rotating around the rotating arm 2, but only bears a small resistance from the connecting structure 103 between the rotating arm 2 and the handle body 1 (such as friction at the rotating shaft), and thus can rotate freely in the vertical direction relative to the rotating arm 2, facilitating angle adjustment.

[0086] When it is necessary to lock the angle of the photographic equipment in the vertical direction, the adjusting knob 31 of the first locking mechanism is rotated to drive the connecting rod 32 to move the rotating arm 2 towards the handle body 1. As the rotating arm 2 approaches the handle body 1, the second toothed disc 6 arranged on the rotating arm 2 gradually approaches the first toothed disc 5 arranged on the third side wall 1013 of the handle body 1. When the rotating arm 2 and the handle body 1 reach a suitable relative position, the second toothed disc 6 is in complete abutment and meshing with the first toothed disc 5, and at this time the rotating arm 2 is in a relatively fixed state with the handle body 1.

[0087] When it is necessary to adjust the angle of the photographic equipment in the vertical direction, the adjusting knob 31 of the first locking mechanism is reversely rotated to drive the connecting rod 32 to reversely rotate, so that the rotating arm 2 moves away from the handle body 1. In this way, the second toothed disc 6 gradually separates from the first toothed disc 5. For example, when the shooting angle is switched from a panoramic view to a close-up view, the photographer reversely rotates the adjusting knob 31 first, so that the second toothed disc 6 is disengaged from the first toothed disc 5, and at this time the rotating arm 2 is in a relatively movable state with the handle body 1, and the user can adjust the photographic equipment to a suitable low-angle or high-angle shooting angle, achieving flexible angle adjustment.

[0088] The present application can realize relatively accurate angle fixation of the rotating arm 2 and the handle body 1 by arranging the first toothed disc 5 and the second toothed disc 6 and cooperating with the first locking mechanism, can ensure the accuracy of the shooting angle, reduce errors caused by slight changes in the angle, and improve the reliability of shooting.

[0089] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the side of the connecting section 102 away from the adjusting knob is recessed with at least one mounting hole 1022, the first toothed disc 5 is provided with a second through hole 51 corresponding to the mounting hole 1022, and the end of the second toothed disc 6 facing the first toothed disc 5 is provided with a plurality of recesses 61 which are distributed at intervals along the circumference of the second toothed disc 6; the photographic equipment connecting handle further comprises:

[0090] A spring 7 is accommodated in the mounting hole 1022, and one end of the spring 7 abuts against the bottom wall of the mounting hole 1022.

[0091] A damping member 8 has one end abutting against the other end of the spring 7 and the other end of the damping member 8 is connected to the recess 61 in a spherical manner.

[0092] In this embodiment, the spring 7 provides a basic elastic force: the spring 7 is placed in the mounting hole 1022 of the third side wall 1013, and one end abuts the bottom wall of the mounting hole 1022. When the rotating arm 2 and the handle body 1 are relatively rotated in the case that the first gear plate 5 and the second gear plate 6 are not engaged, the damping member 8 will be displaced under the influence of external force, and then the spring 7 will be compressed or stretched. This elastic force acts on the damping member 8, and provides a basic force for generating the damping effect. Specifically:

[0093] The middle part of the damping member 8 can slide through the second through hole 51 of the first gear plate 5, one end of the damping member 8 is in contact with the spring 7, and the other end is in spherical connection with the semispherical pit 61 of the second gear plate 6. When the rotating arm 2 and the handle body 1 are relatively rotated, the damping member 8 will move between the pits 61 due to the connection relationship between the spherical end of the damping member 8 and the pit 61. The existence of the pit 61 makes the damping member 8 need to overcome the resistance of the edge of the pit 61 during the movement. Moreover, the elastic force of the spring 7 will generate a pushing or pulling force on the damping member 8 according to the deformation degree of the spring 7. The joint action of the two forces (the resistance of the edge of the pit 61 and the elastic force of the spring 7) makes the relative rotation process of the rotating arm 2 and the handle body 1 generate a damping adjustment effect. That is, the rotating arm 2 and the handle body 1 will be resisted during rotation, and the resistance will dynamically change according to the deformation of the spring 7 and the position of the damping member 8 between the pits 61.

[0094] When the photographer or the operator stops rotating the rotating arm 2 or the handle body 1, the elastic force of the spring 7 will act according to the current deformation state of the spring 7. If the spring 7 is compressed, it will generate an extension force; if it is stretched, it will generate a contraction force. This force will act on the damping member 8, and try to make the damping member 8 return to a relatively balanced position, that is, to be stable in a certain pit 61.

[0095] The application provides the photographer with a tactile feedback through the damping adjustment. During the rotation process, the photographer can intuitively understand the rotation state of the rotating arm 2 and the handle body 1 through the resistance change felt by the hand.

[0096] Please continue to refer to Figure 5 In some embodiments, at least one of the first gear plate 5 and the second gear plate 6 is concavely provided with a mounting groove 6A, and the photographic equipment connecting handle further comprises:

[0097] The elastic reset member 9 is arranged in the mounting groove 6A, one end of the elastic reset member 9 abuts the bottom wall of the mounting groove 6A, and the other end abuts the rotating arm 2.

[0098] In the embodiment, preferably, the mounting groove 6A is arranged at one end of the second toothed disc 6 facing the first toothed disc 5, one end of the elastic return member 9 abuts against the bottom wall of the mounting groove 6A, and the other end abuts against the first toothed disc 5, that is, one end of the elastic return member 9 abuts against the rotating arm 2, and the other end abuts against the handle body 1. When the rotating arm 2 moves towards or away from the handle body 1, the first toothed disc 5 and the second toothed disc 6 will move closer to or away from each other as described in the foregoing embodiment, and the elastic return member 9 between the first toothed disc 5 and the second toothed disc 6 will be compressed or released. For example, when the rotating arm 2 moves towards the handle body 1, the elastic return member 9 is compressed, and an elastic force outward (away from the handle body 1) is generated on the rotating arm 2; when the rotating arm 2 moves away from the handle body 1, the elastic return member 9 is stretched, and an elastic force inward (towards the handle body 1) is generated. The elastic return member 9 is used to provide a certain elastic return effect when the first locking member 3 drives the rotating arm 2 and the handle body 1 to separate, which helps to quickly unlock the rotating arm 2 and the handle body 1.

[0099] With reference to Figures 4 to 7 In some embodiments, the outer wall of the rotating part 21 is configured with external threads, and the second locking member 4 includes:

[0100] The sleeve part 41 is recessed with a connecting groove 41A, and the inner wall of the connecting groove 41A is configured with internal threads matched with the external threads; and the bottom wall of the connecting groove 41A is provided with a third through hole 41B;

[0101] The adapter 42 is accommodated in the connecting groove 41A, one end of the adapter 42 is arranged opposite to the adapter part, and the other end is provided with a connecting bolt 42B corresponding to the third through hole 41B;

[0102] The third through hole 41B is used for exposing the connecting bolt 42B outside the sleeve part 41, and the connecting bolt 42B is used for connecting another external photographic equipment; and the sleeve part 41 is used for driving the adapter 42 to abut against or move away from the rotating arm 2, so that the rotating arm 2 is relatively fixed or relatively movable with the adapter 42.

[0103] In the embodiment, as described in the foregoing embodiment, the second locking member 4 and the rotating part 21 can be connected by threads, specifically:

[0104] When the second locking member 4 is locked on the rotating part 21, the friction between the two and the fastening force of the threads make the rotating arm 2 and the second locking member 4 form a rigid whole, which limits the rotation of the rotating arm 2 around the second locking member 4, and ensures the stability of the photographic equipment in the horizontal direction. When the second locking member 4 is released from the rotating part 21, the rotating arm 2 can rotate horizontally around the second locking member 4, which utilizes the separable characteristic of the threaded connection, and controls the rotation freedom degree of the rotating arm 2 in the horizontal direction by changing the connection tightness of the threads.

[0105] The external thread of the outer wall of the rotating part 21 is matched with the internal thread of the inner wall of the connecting groove 41A of the sleeve part 41. According to the characteristics of the thread, when the sleeve part 41 is rotated, the sleeve part 41 will move along the axial direction of the rotating part 21 due to the interaction of the thread.

[0106] The adapter part 42 is located in the connecting groove 41A of the sleeve part 41, and one end thereof is arranged opposite to the rotating arm 2. When the sleeve part 41 moves along the axial direction, the adapter part 42 will be pushed or pulled, so as to change the distance between the adapter part 42 and the rotating arm 2. When the adapter part 42 abuts against the rotating arm 2, the rotating arm 2 is relatively fixed with the adapter part 42 by the action of the friction and the pressure; when the adapter part 42 is away from the rotating arm 2, the rotating arm 2 is not abutted against the adapter part 42 or the friction therebetween is reduced, and the rotating arm 2 can relatively move around the adapter part 42.

[0107] The connecting bolt 42B arranged at the other end of the adapter part 42 is exposed outside the sleeve part 41 through the third through hole 41B, and the connecting bolt 42B is used for connecting another external photographic equipment. In this way, the indirect connection between another external photographic equipment and the handle body 1 is realized, and the relative movement state therebetween can be adjusted as needed.

[0108] When it is needed to relatively fix the rotating arm 2 with the adapter part 42 to limit the rotation of the photographic equipment in the horizontal direction, the sleeve part 41 is rotated to move along the rotating part 21 towards the rotating arm 2 through the threaded connection. With the approach of the sleeve part 41, the adapter part 42 located in the connecting groove 41A is pushed by the sleeve part 41 to move towards the rotating arm 2.

[0109] The adapter part 42 finally abuts against the rotating arm 2, and the rotating arm 2 is in close contact with the adapter part 42 under the action of the pressure and the friction. At this time, since the friction is large enough, the rotation of the rotating arm 2 around the adapter part 42 is prevented, the relative fixation of the rotating arm 2 with the adapter part 42 is realized, and the stability of another external photographic equipment connected to the adapter part 42 in the horizontal direction is ensured, so that the horizontal rotation of the another external photographic equipment due to accidental external force is avoided.

[0110] When it is needed to adjust the angle of the photographic equipment in the horizontal direction, the sleeve part 41 is reversely rotated. According to the thread transmission principle, the sleeve part 41 will move away from the rotating arm 2 along the axial direction of the rotating part 21.

[0111] The movement of the sleeve part 41 drives the adapter part 42 to move away from the rotating arm 2, so that the distance between the adapter part 42 and the rotating arm 2 is increased, and the friction therebetween is reduced. At this time, the rotating arm 2 can relatively freely rotate around the adapter part 42, so that the adjustment of the angle of the photographic equipment in the horizontal direction is realized.

[0112] The second locking member 4 with the above structure is arranged in the application, and the following beneficial effects are realized:

[0113] Firstly, by simply rotating the sleeve 41, the relative fixation or relative movement between the rotating arm 2 and the adapter 42 can be achieved, thereby conveniently controlling the horizontal rotation freedom of the photographic equipment.

[0114] Secondly, in the locked state, the adapter 42 is in close abutment with the rotating arm 2, which can effectively prevent unintended rotation of the photographic equipment in the horizontal direction.

[0115] Thirdly, the connecting bolt 42B on the adapter 42 can be designed in various forms to adapt to different types of external photographic equipment and meet the equipment combination requirements in different shooting scenes, thereby improving the flexibility and practicality of the entire photographic equipment system. For example, a 1 / 4 screw hole is provided on the connecting bolt 42B, which is only illustrative.

[0116] Please continue to refer to Figures 4 to 7 In some embodiments, the end of the rotating part 21 facing the adapter 42 is provided with a first tooth surface 21A, and the end of the adapter 42 facing the rotating part 21 is provided with a second tooth surface 42A, and the first tooth surface 21A can be engaged with the second tooth surface 42A.

[0117] In this embodiment, the first tooth surface 21A and the second tooth surface 42A are respectively arranged at the opposite ends of the rotating part 21 and the adapter 42, and their shapes and tooth structures are adapted to each other. They can be directly formed on the rotating part 21 and the adapter 42, or they can be a detachable connection structure such as the first tooth disc 5 and the second tooth disc 6, which is only illustrative and not limited.

[0118] When the first tooth surface 21A and the second tooth surface 42A are engaged, the teeth are interlaced and fitted with each other, and the engagement of the tooth surfaces can transmit force and torque. Due to the shape and arrangement of the teeth, a large resistance is generated in the horizontal direction to prevent the relative rotation of the rotating arm 2 and the adapter 42.

[0119] In some embodiments, the first tooth surface 21A and the second tooth surface 42A can be directly formed on the ends of the rotating part 21 and the adapter 42, or they can be a tooth disc design such as the first tooth disc 5 and the second tooth disc 6, which is detachably connected with the rotating part 21 and the adapter 42.

[0120] Refer to Figures 6 to 9 In some embodiments, the connecting structure 103 includes a pipe groove 1031 recessed at one end of the holding section 101 away from the connecting section 102, and the pipe groove 1031 is used to connect the circular pipe-shaped photographic equipment. The photographic equipment connecting handle further includes:

[0121] The damping adjusting member 10 includes a handle 10A and a screw rod 10B connected with each other.

[0122] At least one of the first side wall 1011, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014 is provided with a first connecting hole 1001 communicating with the pipe slot 1031, the screw rod 10B can be arranged in the first connecting hole 1001 and is in threaded connection with the first connecting hole 1001, and the handle 10A is used to drive the screw rod 10B to abut against the circular tube-shaped photographic equipment in the pipe slot 1031 by external force.

[0123] In the embodiment, the pipe slot 1031 is recessed at one end of the holding section 101 away from the connecting section 102, that is, can be arranged at the end face of the first side wall 1011, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014 on the same side of the connecting section 102, that is, the pipe slot 1031 and the rotary arm 2 are arranged at two ends of the handle body 1, the shape of the pipe slot 1031 is matched with the shape of the circular tube-shaped photographic equipment, for example, a connecting pipe commonly used in the photographic industry with a diameter of ≤16 mm. By inserting the circular tube-shaped photographic equipment into the pipe slot 1031, the preliminary connection between the two can be achieved.

[0124] The screw rod 10B of the damping adjusting member 10 is in threaded connection with the first connecting hole 1001 arranged on the side wall (the first side wall 1011, the second side wall 1012, the third side wall 1013 or the fourth side wall 1014) of the handle body 1. When the handle 10A is rotated, according to the threaded transmission principle, the screw rod 10B will move in the axial direction in the first connecting hole 1001. Since the screw rod 10B is arranged opposite to the circular tube-shaped photographic equipment in the pipe slot 1031, when the screw rod 10B abuts against the circular tube-shaped photographic equipment, a damping effect is generated on the circular tube-shaped photographic equipment by the friction force, thereby limiting the rotation or movement of the circular tube-shaped photographic equipment in the pipe slot 1031.

[0125] According to the shooting requirement, if it is necessary to limit the rotation or movement of the circular tube-shaped photographic equipment in the pipe slot 1031, for example, when it is necessary to keep the angle of a certain auxiliary lighting lamp stable during shooting, the handle 10A of the damping adjusting member 10 is operated. The handle 10A is rotated, driving the screw rod 10B to rotate in the first connecting hole 1001 and move in the axial direction to the circular tube-shaped photographic equipment in the pipe slot 1031. As the screw rod 10B gradually abuts against the circular tube-shaped photographic equipment, the friction force between the two gradually increases, thereby achieving the damping adjustment of the circular tube-shaped photographic equipment, making the rotation or movement of the circular tube-shaped photographic equipment in the pipe slot 1031 difficult, and achieving the stable effect. If it is necessary to remove the damping, the handle 10A is reversely rotated, so that the screw rod 10B moves away from the circular tube-shaped photographic equipment, the friction force between the two is reduced, and the freedom of the circular tube-shaped photographic equipment in the pipe slot 1031 is restored.

[0126] The application achieves the following beneficial effects by the above structure:

[0127] The pipe groove 1031 provides a special connecting position for the circular pipe-shaped photographic equipment, so that the circular pipe-shaped photographic equipment can be stably connected with the handle body 1.

[0128] The damping adjusting part 10 can flexibly adjust the damping size of the circular pipe-shaped photographic equipment in the pipe groove 1031 according to the shooting requirements. The photographer can accurately control the friction force between the screw rod 10B and the circular pipe-shaped photographic equipment according to different shooting scenes and the stability requirements of the circular pipe-shaped photographic equipment, so as to realize the accurate control of the rotation or movement of the circular pipe-shaped photographic equipment.

[0129] Please continue to refer to Figures 6 to 9 In some embodiments, the bottom wall of the pipe groove 1031 is provided with a receiving hole 1032, the screw rod 10B can extend into the receiving hole 1032, the peripheral wall of the pipe groove 1031 is provided with a profiling groove 1033, the profiling groove 1033 is matched with the shape of the handle 10A, and the handle 10A is accommodated in the pipe groove 1031.

[0130] At least one of the first side wall 1011, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014 is further provided with a second connecting hole 1002, and the second connecting hole 1002 is communicated with the profiling groove 1033; the photographic equipment connecting handle further comprises:

[0131] The handle locking part 11 is threaded into the second connecting hole 1002, one end of the handle locking part 11 can extend out of the second connecting hole 1002, and the handle locking part 11 extends into the profiling groove 1033 and abuts against the handle 10A.

[0132] In the embodiment, the receiving hole 1032 of the bottom wall of the pipe groove 1031 is threaded with the screw rod 10B, when the damping adjustment is not needed, the screw rod 10B can extend into the receiving hole 1032, the profiling groove 1033 of the peripheral wall of the pipe groove 1031 is matched with the shape of the handle 10A, the profiling groove 1033 is used to form a storage space for the handle 10A in cooperation with the pipe groove 1031 when the screw rod 10B is accommodated in the receiving hole 1032. The handle 10A can be placed in the profiling groove 1033 and the pipe groove 1031, so that the entire damping adjusting part 10 can not be exposed to the handle body 1 when not in use, reducing the risk of collision caused by protruding parts, and making the overall appearance of the handle more regular, facilitating carrying and storage.

[0133] The handle locking part 11 is threaded into the second connecting hole 1002, one end of the handle locking part 11 can extend out of the second connecting hole 1002, and the handle locking part 11 extends into the profiling groove 1033 and abuts against the handle 10A. In this way, the handle 10A can be firmly fixed in the profiling groove 1033, preventing the handle 10A from being accidentally knocked out of the profiling groove 1033 or shaken out of the profiling groove 1033 during the movement or carrying of the equipment, further ensuring the stability and safety of the entire device in the non-use state.
