Description

Technical Field

[0001] The present invention relates to the technical field of photographic equipment, and more particularly to a photographic equipment fixing device and the photographic equipment. Background Art

[0002] In the field of photography, fixtures for photographic equipment (such as cameras, camcorders, and mobile phones) are common accessories. Their primary function is to securely hold the equipment in place, ensuring stability during filming and preventing any shaking that may affect the quality of the shot. Conventional fixtures typically include a base, a clamping structure, and a locking mechanism. The clamping structure holds the equipment in place, and the locking mechanism locks the clamping structure in place to prevent it from loosening or falling off.

[0003] However, the currently common fixing devices for photographic equipment have certain limitations during use. Specifically, the movements of the locking mechanism and the clamping structure of the existing fixing device are often interrelated. When the locking mechanism is in the locked state, the clamping structure is usually completely fixed and cannot be flexibly adjusted in the clamping direction or the loosening direction. This results in the user needing to first operate the locking mechanism to unlock the device when installing the photographic equipment, and then adjust the clamping structure before re-locking it. The operation process is relatively cumbersome, affecting the convenience of use. Especially when the position of the photographic equipment needs to be quickly adjusted to adapt to changes in the shooting scene, this operational inconvenience will significantly reduce work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a photographic equipment fixing device and photographic equipment to solve the technical problem in the prior art that the photographic equipment fixing device is completely fixed when the clamping structure of the photographic equipment fixing device is in a locked state, but has poor flexibility.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, a photographic equipment fixing device is provided, comprising:

[0007] A base, a support provided on the base, a clamping member provided on the support, and a triggering member transmission-connected to the clamping member;

[0008] wherein the support is provided with a guide rail and a limiting structure provided on the guide rail, the clamping member defines a clamping direction parallel to the length direction of the guide rail and a loosening direction opposite to the clamping direction, the clamping member is slidably connected to the guide rail, the trigger member defines a locking direction and an unlocking direction perpendicular to the length direction of the guide rail, the trigger member is slidably connected to the base, the clamping member is provided with a first guide groove parallel to the loosening direction and a second guide groove connected to the first guide groove, the second guide groove is parallel to the unlocking direction, the trigger member is provided with a guide structure slidably provided in the first guide groove and the second guide groove, and the trigger member is further provided with a limiting protrusion cooperating with the limiting structure;

[0009] When the trigger member moves along the unlocking direction to the unlocking position, so that the limiting protrusion abuts against the limiting structure, the guide structure just moves into the first guide groove and is confined to move in the first guide groove, so that the clamping member can move along the clamping direction or the loosening direction; when the trigger member moves along the locking direction to the locking position, so that the limiting protrusion passes over the limiting structure, the guide structure just moves into the second guide groove and is confined to move in the second guide groove.

[0010] By adopting the above technical solution and through the precise coordination of various components, the state of the device when the trigger is in different positions is clarified, and the flexible movement of the clamping part along the clamping and loosening directions in the unlocked state and the stable limiting in the locked state are realized. This not only ensures the convenience during installation and adjustment of the photographic equipment, but also ensures the stability after fixation. The structural design is ingenious, and the orderly switching of functions is realized through the coordination of the guide structure and different guide grooves, thereby improving the practicality and reliability of the device.

[0011] In one embodiment, the trigger member is provided with a limiting groove, and the limiting protrusion is formed at one end of the limiting groove.

[0016] In one embodiment, the support is provided with a guide column for guiding the clamping member to move in the clamping direction and the loosening direction, the clamping member is provided with a second inclined surface, and the trigger member is provided with a second pushing surface that slides into contact with the second inclined surface. The trigger member moves along the locking direction, so that the second pushing surface pushes the second inclined surface, so that the clamping member and the support can move along the clamping direction.

[0017] In one embodiment, the photographic equipment fixing device also includes a locking member that is transmission-connected to the trigger member; the locking member is connected to the base shaft, and the locking member includes a cam and a lever connected to the cam, and the lever drives the cam to rotate around the axis after being subjected to force, and the cam drives the trigger member to move along the locking direction.

[0041] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating relative importance or indicating the number of technical features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited. The specific implementation of the present application will be described in more detail below in combination with specific embodiments:

[0042] As shown in Figure 1 and Figure 2 The photographic equipment fixing device provided by the embodiment of the present application comprises:

[0043] The base 1, the support 2 provided on the base 1, the clamping piece 3 provided on the support 2, and the trigger piece 4 in transmission connection with the clamping piece 3;

[0044] Please refer to Figure 3 and Figure 4, wherein the support 2 is provided with a guide rail 21 and a limiting structure 22 provided on the guide rail 21, the clamping member 3 is defined with a clamping direction R1 parallel to the length direction of the guide rail 21 and a loosening direction R2 opposite to the clamping direction R1, the clamping member 3 is slidably connected to the guide rail 21, the trigger member 4 is defined with a locking direction R3 and an unlocking direction R4 perpendicular to the length direction of the guide rail 21, the trigger member 4 is slidably connected to the base 1, the clamping member 3 is provided with a first guide groove 31 parallel to the loosening direction R2 and a second guide groove 32 connected to the first guide groove 31, the second guide groove 32 is parallel to the unlocking direction R4, the trigger member 4 is provided with a guide structure 41 slidably provided in the first guide groove 31 and the second guide groove 32, and the trigger member 4 is further provided with a limiting protrusion 42 cooperating with the limiting structure 22;

[0045] When the trigger member 4 moves to the unlocking position along the unlocking direction, so that the limiting protrusion 42 abuts against the limiting structure 22, the guide structure 41 just moves into the first guide groove 31 and is confined to move in the first guide groove 31, so that the clamping member 3 can move along the clamping direction or the loosening direction; when the trigger member 4 moves to the locking position along the locking direction, so that the limiting protrusion 42 passes over the limiting structure 22, the guide structure 41 just moves into the second guide groove 32 and is confined in the second guide groove 32.

[0046] Specifically, the structural composition of the photographic equipment fixing device includes a base 1, a support 2 arranged on the base 1, a clamping member 3 arranged on the support 2, and a triggering member 4 that is transmission-connected to the clamping member 3; wherein, a guide rail 21 and a limiting structure 22 located on the guide rail 21 are provided on the support 2, the clamping member 3 is defined with a clamping direction R1 parallel to the length direction of the guide rail 21 and an opposite loosening direction R2, and the clamping member 3 is slidingly connected to the guide rail 21, the triggering member 4 is defined with a locking direction R3 and an unlocking direction R4 perpendicular to the length direction of the guide rail 21, and the triggering member 4 is slidingly connected to the base 1, a first guide groove 31 parallel to the loosening direction R2 and a second guide groove 32 connected with the clamping member 3 and parallel to the unlocking direction R4 are provided, the triggering member 4 is provided with a guide structure 41 slidably arranged on the above-mentioned two guide grooves and a limiting protrusion 42 cooperating with the limiting structure 22.

[0047] like Figure 5As shown, the working principle of the photographic equipment fixing device provided in this embodiment is as follows: when the trigger member 4 moves to the unlocking position along the unlocking direction R4, so that the limiting protrusion 42 abuts the limiting structure 22, the guide structure 41 just moves into the first guide groove 31 and is limited in movement therein, and the clamping member 3 can now move freely along the clamping direction R1 or the loosening direction R2. For example, the user clamps the photographic equipment body between the two clamping members 3. At this time, the photographic equipment body applies a force upward so that the clamping member 3 can move along the loosening direction R2, thereby causing the two oppositely arranged clamping members 3 to open until the photographic equipment body enters between the two clamping members 3. After the photographic equipment body is fully entered, the two clamping members 3 return to their original positions under the action of their own elastic force, that is, the photographic equipment body is clamped between the two clamping members 3.

[0048] like Figure 6 As shown, when the trigger member 4 moves to the locking position along the locking direction R3, so that the limiting protrusion 42 passes over the limiting structure 22, the guide structure 41 just moves into the second guide groove 32 and is confined therein. At this time, the guide structure 41 can only move along the second guide groove 32, thereby keeping the clamping member 3 in the clamping position, thereby realizing that the trigger member 4 locks the clamping member 3 in the clamping position.

[0049] By adopting the above technical solution and through the precise coordination of various components, the state of the device when the trigger member 4 is in different positions is clarified, and the flexible movement of the clamping member 3 along the clamping and loosening directions in the unlocked state and the stable limiting in the locked state are realized, which not only ensures the convenience during installation and adjustment of the photographic equipment, but also ensures the stability after fixation. The structural design is ingenious, and the orderly switching of functions is realized through the coordination of the guide structure 41 and different guide grooves, thereby improving the practicality and reliability of the device.

[0050] Please refer again Figure 4 In one embodiment, the trigger member 4 is provided with a limiting groove 43 , and a limiting protrusion 42 is formed at one end of the limiting groove 43 .

[0051] Specifically, in one embodiment of the photographic equipment fixing device, its structural composition is further clarified on the original basis, a limiting groove 43 is provided on the trigger member 4, and a limiting protrusion 42 is formed at one end of the limiting groove 43.

[0052] When the trigger member 4 moves along the locking direction R3, the limiting protrusion 42 formed at one end of the limiting groove 43 will move accordingly and abut against the limiting structure 22 on the support 2. At this time, the guide structure 41 moves into the first guide groove 31, so that the clamping member 3 can move along the clamping direction R1 or the loosening direction R2; when the trigger member 4 moves along the unlocking direction R4, the limiting protrusion 42 disengages from the limiting structure 22, and the guide structure 41 moves into the second guide groove 32. This embodiment makes it easier to form the limiting protrusion 42 by setting the limiting protrusion 42 as a structure at one end of the limiting groove 43, and can form an integrated structure with the limiting groove 43, thereby enhancing the stability and strength of the overall structure of the trigger member 4. While ensuring that the limiting protrusion 42 and the limiting structure 22 are reliably matched to achieve the locking and unlocking functions, the processing difficulty is reduced, and the stability of the adjustment of the clamping member 3 in the locked state and the smoothness of the unlocking operation are further improved, thereby better achieving the technical effect of free movement of the clamping member 3 in the locked state and combining reliability and convenience.

[0053] like Figure 7 As shown, in one embodiment, the limiting structure 22 is provided with a limiting arc surface 221 that abuts against the limiting protrusion 42 .

[0054] Specifically, when the trigger member 4 moves along the locking direction R3, the limiting protrusion 42 on the trigger member 4 will abut against the limiting arc surface 221 of the limiting structure 22 on the support 2. At this time, the guide structure 41 moves into the first guide groove 31, and the clamping member 3 can move along the clamping direction R1 or the loosening direction R2; when the trigger member 4 moves along the unlocking direction R4, the limiting protrusion 42 disengages from the limiting arc surface 221 of the limiting structure 22, and the guide structure 41 moves into the second guide groove 32.

[0055] By adopting the above technical solution, the abutment between the limiting arc surface 221 and the limiting protrusion 42 is smoother, which can reduce the friction and wear when the two are in contact, so that the trigger member 4 can move more smoothly in the locking direction R3 and the unlocking direction R4, and improve the operating feel; at the same time, the arc surface contact can increase the contact area, so that the limiting protrusion 42 and the limiting structure 22 can cooperate more firmly, and the position of the trigger member 4 can be more reliably limited in the locked state, further ensuring the stability of the clamping member 3 moving along the clamping direction R1 and the loosening direction R2 in the locked state, thereby enhancing the reliability and durability of the entire device.

[0056] like Figure 8 As shown, in one embodiment, the clamping member 3 is provided with a first elastic member 33 connected to the support 2 , and the elastic force direction of the first elastic member 33 is parallel to the clamping direction R1 .

[0057] Specifically, the clamping member 3 is provided with a first elastic member 33 connected to the support 2 , and the elastic force direction of the first elastic member 33 is parallel to the clamping direction R1 . The first elastic member 33 is used to provide elastic force for the clamping member 3 to move along the clamping direction R1 .

[0058] When the trigger member 4 moves along the locking direction R3 so that the limiting protrusion 42 abuts against the limiting arc surface 221 of the limiting structure 22, and the guide structure 41 is located in the first guide groove 31, the first elastic member 33 will continue to apply an elastic force parallel to the clamping direction R1 to the clamping member 3, pushing the clamping member 3 to move along the clamping direction R1 without the action of external force, thereby realizing automatic clamping of the photographic equipment; when the photographic equipment needs to be loosened, an external force along the loosening direction R2 is applied to the clamping member 3, which can overcome the elastic force of the first elastic member 33 and make the clamping member 3 move along the loosening direction R2; and when the trigger member 4 moves along the unlocking direction R4 so that the limiting protrusion 42 disengages from the limiting structure 22, and the guide structure 41 is located in the second guide groove 32, the elastic force of the first elastic member 33 will act on the clamping member 3, but because the guide structure 41 is confined in the second guide groove 32, the clamping member 3 cannot move along the clamping direction R1 or the loosening direction R2.

[0059] By adopting the above-mentioned technical solution, the first elastic member 33 can provide the clamping member 3 with a continuous elastic force in the clamping direction R1, so that the clamping member 3 can automatically clamp the photographic equipment under the action of the elastic force in the locked state, without the need to manually and continuously apply the clamping force, thereby improving the convenience of operation; at the same time, when loosening, it is only necessary to apply an external force to overcome the elastic force to adjust it, which saves effort in operation, and the elastic force can ensure the stability of the clamping force, thereby preventing the photographic equipment from loosening due to insufficient clamping force, further enhancing the reliability and convenience of the device in clamping the photographic equipment in the locked state.

[0060] Please also refer to Figures 8 to 10 In one embodiment, the clamping member 3 is provided with a first inclined surface 34, and the triggering member 4 is provided with a first pushing surface 44 that slides against the first inclined surface 34. The triggering member 4 moves along the unlocking direction R4, so that the first pushing surface 44 pushes the first inclined surface 34, so that the clamping member 3 can move along the loosening direction R2.

[0061] Specifically, when the trigger member 4 moves along the unlocking direction R4, in addition to making the limiting protrusion 42 abut against the limiting arc surface 221 of the limiting structure 22 and the guide structure 41 move into the first guide groove 31, the first pushing surface 44 on the trigger member 4 will slide and abut against the first inclined surface 34 on the clamping member 3. As the trigger member 4 continues to move along the unlocking direction R4, the first pushing surface 44 will generate a pushing force on the first inclined surface 34, and the force will decompose into a component force along the loosening direction R2, thereby driving the clamping member 3 to move along the loosening direction R2; and when the trigger member 4 moves along the locking direction R3, the first pushing surface 44 gradually disengages from the abutment with the first inclined surface 34, and under the elastic force of the first elastic member 33, the clamping member 3 will move along the clamping direction R1.

[0062] Through the cooperation of the first inclined surface 34 and the first pushing surface 44, the clamping member 3 can be driven to move along the loosening direction R2 while the trigger member 4 is performing the locking operation, without the need for additional manual operation of the clamping member 3, further simplifying the operation process and improving the convenience of use; moreover, the use of the inclined surface to push the force makes the movement of the clamping member 3 more stable and smooth, avoiding the abrupt movement that may occur during manual adjustment, and at the same time, with the action of the first elastic member 33, it can better ensure the stability and reliability of the clamping member 3 in the clamping direction R1 and the loosening direction R2 in the locked state, thereby enhancing the overall performance of the device.

[0063] Please refer again Figure 3 and Figure 7 In one embodiment, the support 2 defines a clamping direction R5 and a loosening direction R6 opposite to the clamping direction R5, the clamping direction R5 is perpendicular to the clamping direction R1, and the support 2 is further provided with a second elastic member 23 connected to the base 1, and the elastic force direction of the second elastic member 23 is parallel to the loosening direction R6.

[0064] Specifically, the support 2 is defined with a clamping direction R5 and an opposite loosening direction R6, and the clamping direction R5 is perpendicular to the clamping direction R1. At the same time, a second elastic member 23 connected to the base 1 is provided on the support 2. The elastic force direction of the second elastic member 23 is parallel to the loosening direction R6, and is used to provide the support 2 with elastic force to move along the loosening direction R6.

[0065] When an external force is applied to the support 2 along the clamping direction R5, the support 2 will overcome the elastic force of the second elastic member 23 and move along the clamping direction R5. After the external force is removed, the elastic force of the second elastic member 23 will push the support 2 to reset along the loosening direction R6. When the trigger member 4 moves along the locking direction R3 so that the limiting protrusion 42 abuts against the limiting structure 22 and the guide structure 41 is located in the first guide groove 31, the movement of the support 2 will not affect the movement of the clamping member 3 along the clamping direction R1 or the loosening direction R2, and with the action of the first elastic member 33 on the clamping member 3, flexible clamping of photographic equipment of different sizes can be achieved. When the trigger member 4 moves along the unlocking direction R4 so that the limiting protrusion 42 disengages from the limiting structure 22 and the guide structure 41 is located in the second guide groove 32, the movement of the support 2 can also cooperate with the overall structure to ensure the stability of the device.

[0066] By adopting the above-mentioned technical solution, the second elastic member 23 provides the support 2 with elastic force along the loosening direction R6, so that the support 2 can automatically reset after being subjected to external force, thereby improving the convenience of device operation; at the same time, the setting of the clamping direction R5 perpendicular to the clamping direction R1 allows the device to form an auxiliary limit for the photographic equipment from a direction perpendicular to the clamping, and cooperates with the clamping effect of the clamping member 3 to further enhance the stability of the fixation of the photographic equipment, which is particularly suitable for photographic equipment of different thicknesses or shapes, expanding the scope of application of the device, and the presence of elastic force makes the reset process of the support 2 smooth, avoids rigid collision, and extends the service life of the device.

[0067] In one embodiment, the support 2 is provided with a guide column 24 for guiding the clamping member 3 to move in the tightening direction R5 and the loosening direction R6, the clamping member 3 is provided with a second inclined surface 35, and the trigger member 4 is provided with a second pushing surface 45 that slides against the second inclined surface 35. The trigger member 4 moves along the locking direction R3, so that the second pushing surface 45 pushes the second inclined surface 35, so that the clamping member 3 and the support 2 can move along the tightening direction R5.

[0068] Specifically, in this embodiment of the photographic equipment fixing device, the structural composition is further refined on the basis of the previous one. A guide column 24 is provided on the support 2, and its function is to guide the clamping member 3 to move in the tightening direction R5 and the loosening direction R6. At the same time, a second inclined surface 35 is provided on the clamping member 3, and a second abutting surface 45 that slides against the second inclined surface 35 is provided on the trigger member 4.

[0069] When the trigger member 4 moves along the locking direction R3, in addition to causing the limiting protrusion 42 to pass over the limiting structure 22 and the guide structure 41 to move into the second guide groove 32, the second pushing surface 45 on the trigger member 4 will slide and abut against the second inclined surface 35 on the clamping member 3. As the trigger member 4 continues to move along the locking direction R3, the second pushing surface 45 will generate a pushing force on the second inclined surface 35, and this force is decomposed into a component force along the clamping direction R5. Under the guidance of the guide column 24, the clamping member 3 and the support 2 are driven to move together along the clamping direction R5. At this time, the support 2 will overcome the elastic force of the second elastic member 23; and when the trigger member 4 moves in the opposite direction, after the second pushing surface 45 is disengaged from the second inclined surface 35, the elastic force of the second elastic member 23 will push the support 2 and the clamping member 3 to reset along the releasing direction R6.

[0070] By setting the guide column 24, the stability and accuracy of the movement of the clamping member 3 and the support 2 in the tightening direction R5 and the loosening direction R6 are guaranteed, and deviation is avoided; by utilizing the cooperation of the second inclined surface 35 and the second push surface 45, the unlocking operation of the trigger member 4 can synchronously drive the clamping member 3 and the support 2 to move along the tightening direction R5, without the need for additional manual operation, simplifying the operation process and improving the convenience of use; at the same time, this cooperation method makes the movement process smoother, and combined with the reset effect of the second elastic member 23, the reliability of the device when switching between different states is further enhanced, so that the device can better adapt to the clamping and adjustment requirements of the photographic equipment.

[0071] Please also refer to Figure 3 and Figure 11 In one embodiment, the photographic equipment fixing device further includes a locking member 5 that is transmission-connected to the trigger member 4; the locking member 5 is axially connected to the base 1, and the locking member 5 includes a cam 51 and a lever 52 connected to the cam 51. When the lever 52 is subjected to force, it drives the cam 51 to rotate around the axis, and the cam 51 drives the trigger member 4 to move along the locking direction R3.

[0072] Specifically, in one embodiment of the photographic equipment fixing device, the structural composition is newly provided with a locking member 5 connected to the trigger member 4 in a transmission manner on the basis of the original structure. The locking member 5 is axially connected to the base 1 and includes a cam 51 and a lever 52 connected to the cam 51.

[0073] When external force is applied to the lever 52, the lever 52 drives the cam 51 to rotate around the connecting axis with the base 1. The rotating cam 51 generates a thrust on the trigger member 4, driving the trigger member 4 to move along the locking direction R3, thereby causing the limiting protrusion 42 on the trigger member 4 to abut against the limiting structure 22 on the support 2, and the guide structure 41 to move into the first guide groove 31 of the clamping member 3. At the same time, the second pushing surface 45 of the trigger member 4 pushes the second inclined surface 35 of the clamping member 3 to move the support 2 and the clamping member 3 along the pressing direction R5, realizing the locking process of the device; when the lever 52 is toggled in the opposite direction, driving the cam 51 to rotate in the opposite direction, the thrust of the cam 51 on the trigger member 4 disappears, and the trigger member 4 can move along the unlocking direction R4 under the relevant force. At this time, the second abutting surface of the trigger member 4 cancels the force applied to the second inclined surface 35 of the clamping member 3, and the support 2 drives the clamping member 3 to move along the releasing direction R6 under the elastic force of the second elastic member 23.

[0074] By adopting the above technical solution, the locking member 5 composed of the cam 51 and the lever 52 is used to convert the rotation of the lever 52 into a linear movement of the trigger member 4. By utilizing the eccentric characteristic of the cam 51, the trigger member 4 can be reliably driven to move along the locking direction R3 with a smaller lever force, and the operation is more labor-saving. At the same time, the shaft connection method ensures the stability of the rotation of the locking member 5. The setting of the lever 52 makes the operation more convenient, which is convenient for the user to quickly lock the device, further improving the operating experience of the device and the reliability of the locking process, so that the device can more efficiently complete the fixing operation of the photographic equipment when in use.

[0075] In one embodiment, the locking member 5 includes a claw 53 provided on the lever 52 and a switch 54 transmission-connected to the claw 53; a tooth row 11 engaged with the claw 53 is provided on the base 1; a third elastic member 55 is provided between the claw 53 and the lever 52; the third elastic member 55 is used to provide elastic force for the claw 53 to engage with the tooth row 11, so that the cam 51 is positioned at a preset position; and the switch 54 is driven by force to disengage the claw 53 from the tooth row 11.

[0076] Specifically, the locking member 5 also includes a claw 53 arranged on the lever 52 and a switch 54 that is transmission-connected to the claw 53. The base 1 is provided with a tooth row 11 that can be engaged with the claw 53, and a third elastic member 55 is provided between the claw 53 and the lever 52. The elastic force of the third elastic member 55 is used to prompt the claw 53 to engage with the tooth row 11.

[0077] When the lever 52 drives the cam 51 to rotate to a preset position (such as a position that puts the trigger member 4 in a locked state), the elastic force of the third elastic member 55 will push the claw 53 to engage in the tooth row 11 of the base 1. Through the engagement of the claw 53 with the tooth row 11, the rotation of the lever 52 and the cam 51 is restricted, so that the cam 51 is stably positioned in the preset position, ensuring that the locking state of the trigger member 4 is stable; when the position of the cam 51 needs to be adjusted, an external force is applied to the switch 54, and the switch 54 will drive the claw 53 to overcome the elastic force of the third elastic member 55 and disengage from the tooth row 11. At this time, the lever 52 and the cam 51 are no longer restricted by the claw 53 and the tooth row 11, and can rotate freely, so as to drive the trigger member 4 to move along the unlocking direction R4 or adjust to other positions.

[0078] By adopting the above technical solution, the cam 51 can be accurately positioned at the preset position through the cooperation of the claw 53, the tooth row 11 and the third elastic member 55, thereby avoiding the loosening of the trigger member 4 due to accidental rotation of the cam 51 caused by vibration, accidental touch, etc., and significantly improving the reliability of the locking state of the device; at the same time, the setting of the switch 54 makes it convenient to disengage the claw 53 from the tooth row 11, and the positioning can be released by applying only a small external force, thereby ensuring the flexibility of the rotation adjustment of the cam 51, further optimizing the operating experience of the device, allowing users to quickly switch between stable locking and flexible adjustment, and enhancing the practicality of the device.

[0079] In a second aspect, a photographic device is provided, comprising a photographic device body and the above-mentioned photographic device fixing device, wherein the photographic device body and the photographic device fixing device are detachably connected.

[0080] By adopting the above technical solution, on the basis of having the advantages of the photographic equipment fixing device of the above embodiment, the photographic equipment of this embodiment also takes into account the stability during fixing and the operational flexibility.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
