Description

Technical Field

[0001] This invention relates to the field of camera support device technology, and in particular to an auxiliary handle for a camera bracket and a camera support device. Background Technology

[0002] As living standards continue to improve, more and more people are falling in love with photography, and the main equipment used for photography includes cameras and mobile phones.

[0003] To improve camera safety, some customers choose to install camera mounts. Camera mounts also provide mounting points for other auxiliary accessories. Handgrips, as one of the camera's auxiliary accessories, make it easier for users to hold the camera. However, most handgrips are currently fixedly connected to camera mounts. When users hold the handgrip to adjust the camera's angle, they need to bend their wrists or arms. Prolonged bending of the wrists or arms can easily lead to soreness, affecting the user experience. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an auxiliary handle for a camera holder, which can improve the problem of users experiencing soreness when adjusting the camera angle by bending their wrists or arms.

[0005] The present invention also proposes a camera support device having an auxiliary handle of the above-mentioned camera bracket.

[0006] An auxiliary handle for a camera bracket according to a first aspect of the present invention includes: a housing having an inner cavity, and the side wall of the housing having an arc-shaped guide groove communicating with the inner cavity and a shaft hole communicating with the inner cavity; an operating component, one end of the operating component protruding from the housing, and the other end of the operating component passing through the arc-shaped guide groove and extending into the inner cavity; and a clamping component disposed in the inner cavity, the clamping component including an internal gear that drivesly engages with the other end of the operating component, and a [missing information - likely a component name] disposed inside the internal gear and meshing with the internal gear. An external gear, a guide member for guiding the external gear to move axially along the external gear when the external gear rotates, and a clamping member disposed on the inner side of the external gear and having a clamping hole, the operating component being movable along the arc-shaped guide groove and driving the internal gear to rotate, the external gear disengaging from the clamping member when moving along the axis of the external gear in a first direction, and abutting against the clamping member when moving along the axis of the external gear in a second direction opposite to the first direction; and a rotating shaft passing through the shaft hole and extending into the clamping hole.

[0007] The auxiliary handle of the camera bracket according to an embodiment of the present invention has at least the following beneficial effects:

[0008] In the auxiliary handle of the camera bracket of the present invention, the operating component can be operated by hand; that is, the user can push the operating component to move it along the arc-shaped guide groove. When the operating component moves along the arc-shaped guide groove under the user's operation, it drives the internal gear to rotate, thereby causing the internal gear to drive the external gear to rotate. When the external gear rotates, it can move along its axial direction under the guidance of the guide member. Specifically, when the operating component moves in the unlocking direction (clockwise), it drives the internal and external gears to rotate clockwise, thereby causing the external gear to move in a first direction under the action of the guide member; when the operating component moves in the locking direction (counterclockwise), it drives the internal and external gears to rotate counterclockwise, thereby causing the external gear to move in a second direction under the action of the guide member. When the external gear moves in the first direction, it gradually loosens from the clamping member; when it moves in the second direction, it gradually tightens against the clamping member. When the clamping element disengages from the external gear, the force exerted by the external gear on the clamping element decreases, allowing the clamping element to loosen and the rotating shaft to rotate freely. When the clamping element is engaged with the external gear, the external gear applies a force to the clamping element, causing it to clamp the rotating shaft and restrict its rotation. When the rotating shaft is loose, the user can adjust the angle of the camera mount, thereby adjusting the camera angle. When the rotating shaft is clamped, the camera mount is fixed to the auxiliary handle under the action of the rotating shaft, ensuring that the auxiliary handle stably supports the camera mount and thus ensuring stable camera support. When holding the auxiliary handle of this invention, the user only needs to use their thumb to control the operation component to release the pivot and clamp, thereby adjusting the angle of the camera mount. Furthermore, while holding the auxiliary handle with one hand, the user's thumb can control the operation component to release the pivot and clamp, while the other hand can be used to adjust the angle of the camera mount, thus changing the camera angle. This operation is convenient, and this method of adjusting the camera angle does not require the user to bend their arm or wrist, thus alleviating the pain that often occurs when adjusting the camera angle by bending the wrist or arm. In addition, the operation component controls the rotation of the internal gear through an arc-shaped motion; therefore, when the user moves their thumb to control the operation component, they can still maintain a stable hand position on the auxiliary handle, reducing the risk of the auxiliary handle falling and ensuring high safety.

[0009] According to some embodiments of the present invention, the operating component includes a drive shaft and a push button connected to one end of the drive shaft, the push button being located outside the housing, and the drive shaft passing through the arc-shaped guide groove and being fixedly connected to the internal gear.

[0010] According to some embodiments of the present invention, a first guide portion is provided on the outer periphery of the external gear, the guide member is sleeved on the outside of the external gear, and a second guide portion is provided on the inner wall of the guide member to guide and cooperate with the first guide portion.

[0011] According to some embodiments of the present invention, the first guide portion is a helical groove, and the second guide portion is a thread, wherein the thread extends into the helical groove.

[0012] According to some embodiments of the present invention, the clamping member is an elastic member, the inner circumferential side of the external gear is provided with a first conical surface, the outer circumferential side of the clamping member is provided with a second conical surface, the first conical surface and the second conical surface are separably abutted, and the small diameter end of the first conical surface and the small diameter end of the second conical surface face the same direction.

[0013] According to some embodiments of the present invention, the clamping member has a plurality of clearance slots, each of the clearance slots penetrating the wall of the clamping hole and the second conical surface, and the plurality of clearance slots are arranged at intervals along the circumference of the clamping hole.

[0014] According to some embodiments of the present invention, the auxiliary handle of the camera bracket further includes a positioning pin, which is fixedly connected to the housing and is positioned and engaged with the inner circumferential side of the internal gear.

[0015] According to some embodiments of the present invention, the operating component can drive the external gear to move in the first direction when it moves along the arcuate guide groove toward the unlocking direction;

[0016] The auxiliary handle of the camera bracket also includes a reset member, one end of which is connected to the housing and the other end of which is connected to the internal gear. The reset member is used to make the operating component tend to move along the arc-shaped guide groove in the locking direction, wherein the unlocking direction is opposite to the locking direction.

[0017] According to some embodiments of the present invention, the reset member is a spring, the spring is disposed in the inner cavity, the side wall of the housing is provided with a first hole and a second hole spaced apart from each other, one end of the spring passes through the first hole and extends to the outside of the housing and then extends into the interior of the inner cavity through the second hole.

[0018] According to a second aspect of the present invention, a camera support device includes: a camera bracket; and an auxiliary handle for the camera bracket as described above, wherein the pivot is fixedly connected to the camera bracket.

[0019] The camera support device according to embodiments of the present invention has at least the following beneficial effects:

[0020] In the camera support device of the present invention, the operating component can be operated by hand; that is, the user can push the operating component to move it along the arc-shaped guide groove. When the operating component moves along the arc-shaped guide groove under the user's operation, it drives the internal gear to rotate, thereby causing the internal gear to drive the external gear to rotate. When the external gear rotates, it can move along its axial direction under the guidance of the guide member. Specifically, when the operating component moves in the unlocking direction (clockwise), it drives the internal and external gears to rotate clockwise, thereby causing the external gear to move in a first direction under the action of the guide member; when the operating component moves in the locking direction (counterclockwise), it drives the internal and external gears to rotate counterclockwise, thereby causing the external gear to move in a second direction under the action of the guide member. When the external gear moves in the first direction, it gradually loosens from the clamping member; when it moves in the second direction, it gradually tightens against the clamping member. When the clamping element disengages from the external gear, the force exerted by the external gear on the clamping element decreases, allowing the clamping element to loosen and the rotating shaft to rotate freely. When the clamping element is engaged with the external gear, the external gear applies a force to the clamping element, causing it to clamp the rotating shaft and restrict its rotation. When the rotating shaft is loose, the user can adjust the angle of the camera mount, thereby adjusting the camera angle. When the rotating shaft is clamped, the camera mount is fixed to the auxiliary handle under the action of the rotating shaft, ensuring that the auxiliary handle stably supports the camera mount and thus ensuring stable camera support. When holding the auxiliary handle of this invention, the user only needs to use their thumb to control the operation component to release the pivot and clamp, thereby adjusting the angle of the camera mount. Furthermore, while holding the auxiliary handle with one hand, the user's thumb can control the operation component to release the pivot and clamp, while the other hand can be used to adjust the angle of the camera mount, thus changing the camera angle. This operation is convenient, and this method of adjusting the camera angle does not require the user to bend their arm or wrist, thus alleviating the pain that often occurs when adjusting the camera angle by bending the wrist or arm. In addition, the operation component controls the rotation of the internal gear through an arc-shaped motion; therefore, when the user moves their thumb to control the operation component, they can still maintain a stable hand position on the auxiliary handle, reducing the risk of the auxiliary handle falling and ensuring high safety.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] like Figure 1 As shown, an embodiment of the present invention relates to a camera support device, which includes a camera bracket 200 and an auxiliary handle 100.

[0037] Combination Figure 2 and Figure 3 The auxiliary handle 100 includes a housing 110, an operating component 120, a clamping component 130, and a rotating shaft 140.

[0038] Combination Figure 2 and Figure 3 The housing 110 has an inner cavity 111, and the side wall of the housing 110 has an arc-shaped guide groove 112 communicating with the inner cavity 111 and a shaft hole 113 communicating with the inner cavity 111.

[0039] Specifically, the housing 110 is a hollow structure with an inner cavity 111. One side wall of the housing 110 is provided with an arc-shaped guide groove 112 and a shaft hole 113, wherein the arc-shaped guide groove 112 and the shaft hole 113 are both connected to the inner cavity 111.

[0040] like Figure 3 As shown, one end of the operating component 120 protrudes from the housing 110, and the other end of the operating component 120 passes through the arc-shaped guide groove 112 and extends into the inner cavity 111.

[0041] Specifically, one end of the operating component 120 is located outside the housing 110, and the other end of the operating component 120 extends into the interior of the inner cavity 111 through the arc-shaped guide groove 112, which guides the operating component 120. The operating component 120 can be operated by hand; that is, the user can push the operating component 120 to move it along the arc-shaped guide groove 112.

[0042] like Figure 3 , Figure 4 As shown, the clamping assembly 130 is disposed in the inner cavity 111. The clamping assembly 130 includes an internal gear 131 that is driven and engaged with the other end of the operating assembly 120, an external gear 132 disposed on the inner side of the internal gear 131 and meshing with the internal gear 131, a guide member 133 for guiding the external gear 132 to move along the axial direction of the external gear 132 when the external gear 132 rotates, and a clamping member 134 disposed on the inner side of the external gear 132 and having a clamping hole 1341.

[0043] The operating component 120 can move along the arc-shaped guide groove 112 and drive the internal gear 131 to rotate. When the external gear 132 moves along the axis of the external gear 132 in the first direction, it is released from the clamping member 134. When the external gear 132 moves along the axis of the external gear 132 in the second direction opposite to the first direction, it abuts against the clamping member 134.

[0044] Specifically, the teeth on the internal gear 131 are located on the inner circumferential side of the internal gear 131, and the teeth on the external gear 132 are located on the outer circumferential side of the external gear 132. The external gear 132 is located on the inner side of the inner gear and meshes with the internal gear 131. When the operating component 120 is moved along the arc-shaped guide groove 112 by the user's operation, the operating component 120 can drive the internal gear 131 to rotate around the axis of the internal gear 131, thereby causing the internal gear 131 to drive the external gear 132 to rotate around the axis of the external gear 132. When the external gear 132 rotates, under the guidance of the guide member 133, the external gear 132 can move along the axial direction of the external gear 132.

[0045] It should be noted that the axial movement of the external gear 132 includes two directions of movement: a first direction of movement along the axis of the external gear 132 and a second direction of movement along the axis of the external gear 132, wherein the first direction is opposite to the second direction.

[0046] Combination Figures 2 to 4It is understood that when the operating component 120 moves in the unlocking direction (clockwise), it drives the internal gear 131 and the external gear 132 to rotate clockwise, thereby causing the external gear 132 to move in the first direction under the action of the guide member 133. When the operating component 120 moves in the locking direction (counterclockwise), it drives the internal gear 131 and the external gear 132 to rotate counterclockwise, thereby causing the external gear 132 to move in the second direction under the action of the guide member 133. Specifically, when the external gear 132 moves in the first direction, it gradually loosens from the clamping member 134; when the external gear 132 moves in the second direction, it gradually tightens against the clamping member 134.

[0047] like Figure 3 , Figure 4 As shown, the rotating shaft 140 passes through the shaft hole 113 and extends into the clamping hole 1341.

[0048] Specifically, one end of the rotating shaft 140 is located outside the housing 110, and the other end of the rotating shaft 140 passes through the shaft hole 113 and extends into the inner cavity 111. Furthermore, the other end of the rotating shaft 140 also passes through the clamping hole 1341 of the clamping member 134. When the clamping member 134 is released from the external gear 132, the force exerted by the external gear 132 on the clamping member 134 decreases, and the rotating shaft 140 can rotate freely. When the clamping member 134 abuts against the external gear 132, the external gear 132 applies a force to the clamping member 134, causing the clamping member 134 to clamp the rotating shaft 140, thus restricting the rotation of the rotating shaft 140.

[0049] Understandably, when the operating component 120 moves in the unlocking direction, the rotating shaft 140 is released and can rotate freely. When the operating component 120 moves in the locking direction, the clamping member 134 clamps the rotating shaft 140, and the rotating shaft 140 is restricted from rotating.

[0050] Combination Figure 1 and Figure 2 It should be noted that the end of the pivot 140 located outside the housing 110 is used to be fixedly connected to the camera bracket 200. The camera bracket 200 is used to support the camera. When the pivot 140 is released, the user can adjust the angle of the camera bracket 200, thereby adjusting the angle of the camera. When the pivot 140 is clamped by the clamping member 134, the camera bracket 200 is fixed to the auxiliary handle 100 under the action of the pivot 140, thereby ensuring that the auxiliary handle 100 stably supports the camera bracket 200, thus ensuring that the camera is stably supported.

[0051] like Figure 4As shown, in one embodiment, a bearing 141 is provided between the hole wall of the shaft hole 113 and the rotating shaft 140, which can improve the service life of the bearing 141.

[0052] like Figures 1 to 4As shown, in the auxiliary handle 100 of the present invention, the operating component 120 can be operated by the user's hand, that is, the user can push the operating component 120 to move the operating component 120 along the arc-shaped guide groove 112. When the operating component 120 moves along the arc-shaped guide groove 112 under the operation of the user, the operating component 120 can drive the internal gear 131 to rotate, thereby causing the internal gear 131 to drive the external gear 132 to rotate. When the external gear 132 rotates, under the guidance of the guide member 133, the external gear 132 can move along the axial direction of the external gear 132. Specifically, when the operating component 120 moves in the unlocking direction (clockwise), it drives the internal gear 131 and the external gear 132 to rotate clockwise, causing the external gear 132 to move in the first direction under the action of the guide member 133. When the operating component 120 moves in the locking direction (counterclockwise), it drives the internal gear 131 and the external gear 132 to rotate counterclockwise, causing the external gear 132 to move in the second direction under the action of the guide member 133. When the external gear 132 moves in the first direction, it gradually loosens from the clamping member 134; when it moves in the second direction, it gradually tightens against the clamping member 134. When the clamping member 134 is released from the external gear 132, the force exerted by the external gear 132 on the clamping member 134 decreases, the clamping member 134 is released, and the rotating shaft 140 can rotate freely. When the clamping member 134 is pressed against the external gear 132, the external gear 132 applies a force to the clamping member 134, causing the clamping member 134 to clamp the rotating shaft 140, thus restricting the rotation of the rotating shaft 140. When the rotating shaft 140 is released, the user can adjust the angle of the camera bracket 200, thereby adjusting the camera angle. When the rotating shaft 140 is clamped by the clamping member 134, the camera bracket 200 is fixed to the auxiliary handle 100 under the action of the rotating shaft 140, thus ensuring that the auxiliary handle 100 stably supports the camera bracket 200, thereby ensuring stable support of the camera. When the user holds the auxiliary handle 100 of this invention, they only need to use their thumb to control the operation component 120 to release the pivot 140 from the clamp 134, thereby allowing the angle of the camera bracket 200 to be adjusted. Furthermore, while the user holds the auxiliary handle 100 with one hand, the thumb of that hand can control the operation component 120 to release the pivot 140 from the clamp 134, while the other hand can be used to adjust the angle of the camera bracket 200, thereby changing the angle of the camera. This operation is convenient, and this method of adjusting the camera angle does not require the user to bend their arm or wrist, which can improve the problem of soreness that users easily feel when adjusting the camera angle by bending their wrist or arm.In addition, the operating component 120 controls the rotation of the internal gear 131 by making an arc-shaped motion. Therefore, when the user swings his thumb to control the operating component 120, he can still maintain the posture of holding the auxiliary handle 100, reducing the risk of the auxiliary handle 100 falling and ensuring high safety.

[0053] like Figure 3 As shown, in one embodiment, the operating component 120 includes a drive shaft 121 and a push button 122 connected to one end of the drive shaft 121. The push button 122 is located outside the housing 110, and the drive shaft 121 passes through the arc-shaped guide groove 112 and is fixedly connected to the internal gear 131. Thus, the user can use their thumb to push the push button 122, thereby causing the rotating shaft 140 to be loosened or clamped.

[0054] like Figure 4 As shown, in one embodiment, the internal gear 131 has more teeth than the external gear 132.

[0055] Specifically, the gear ratio of the internal gear 131 to the external gear 132 is 1.666. Thus, when the internal gear 131 rotates 60°, the external gear 132 will rotate 100°. In this way, when the internal gear 131 rotates a small angle, the clamping member 134 can obtain a large locking force to clamp the rotating shaft 140.

[0056] like Figure 4 As shown, in one embodiment, the outer peripheral side of the external gear 132 is provided with a first guide portion, the guide member 133 is sleeved on the outer side of the external gear 132, and the inner wall of the guide member 133 is provided with a second guide portion that guides and cooperates with the first guide portion.

[0057] It is understood that the outer peripheral side of the external gear 132 is provided with teeth and a first guide portion, and the teeth and the first guide portion are arranged along the axis of the external gear 132. The internal gear 131 is sleeved on the outside of the external gear 132, and the teeth of the internal gear 131 mesh with the teeth of the external gear 132. The guide member 133 is sleeved on the outside of the external gear 132, and the first guide portion and the second guide portion are in a guiding engagement. The first guide portion and the second guide portion cooperate to form a guiding structure. When the external gear 132 rotates under the drive of the internal gear 131, the external gear 132 can move along the axial direction of the external gear 132 under the action of the guiding structure.

[0058] Specifically, the first guide part is a helical groove, and the second guide part is a thread, with the thread extending into the helical groove. In other words, the first guide part and the second guide part are connected by a thread.

[0059] More specifically, the outer circumference of the external gear 132 is provided with a helical groove, the guide 133 is a nut, the guide 133 is fixedly connected to the housing 110, the external gear 132 passes through the nut, and the thread of the nut passes into the helical groove.

[0060] like Figure 4 , Figure 6 As shown, in one embodiment, the clamping member 134 is an elastic member, the inner peripheral side of the external gear 132 is provided with a first conical surface, and the outer peripheral side of the clamping member 134 is provided with a second conical surface 1342. The first conical surface and the second conical surface 1342 are separably abutted, and the small diameter end of the first conical surface and the small diameter end of the second conical surface 1342 face the same direction.

[0061] Specifically, when the first conical surface and the second conical surface 1342 are pressed together, since the clamping member 134 is an elastic member, the external gear 132 presses against the clamping member 134, so that the clamping member 134 clamps the rotating shaft 140. When the external gear 132 moves along the first direction, the first conical surface and the second conical surface 1342 gradually separate. At this time, the clamping member 134 and the rotating shaft 140 will also gradually separate, so that the rotating shaft 140 is released.

[0062] like Figure 3 As shown, more specifically, the large-diameter end of the first cone is located behind the small-diameter end of the first cone along the first direction, so that when the external gear 132 moves along the first direction, the first cone and the second cone 1342 gradually separate.

[0063] like Figure 4 As shown, the taper of the first conical surface is the same as the taper of the second conical surface 1342, and the taper of the first conical surface is in the range of 6°-10°, so that the clamping member 134 can quickly clamp the rotating shaft 140.

[0064] like Figure 6 As shown, the clamping member 134 further includes multiple clearance slots 1343, each of which penetrates the wall of the clamping hole 1341 and the second conical surface 1342, and the multiple clearance slots 1343 are arranged at intervals along the circumference of the clamping hole 1341. Thus, when the first conical surface and the second conical surface 1342 are pressed together, the clamping member 134 deforms, causing the clearance slots 1343 to shrink. When the first conical surface and the second conical surface 1342 are released, the clamping member 134 releases its elasticity and returns to its original position, and the clearance slots 1343 also return to their original position, thereby releasing the rotating shaft 140.

[0065] It should be noted that when the clamping member 134 is released from the external gear 132, the rotating shaft 140 can be rotated by operation, which can drive the clamping member 134 to rotate together, thereby reducing the friction on the rotating shaft 140 and improving the service life of the rotating shaft 140.

[0066] Of course, in other embodiments, when the clamping member 134 is released from the external gear 132, the clamping member 134 can also be released from the rotating shaft 140, and the rotating shaft 140 does not drive the clamping member 134 to rotate when it rotates.

[0067] Combination Figure 3 and Figure 5 In one embodiment, the auxiliary handle 100 further includes a positioning pin 150, which is fixedly connected to the housing 110 and engages with the inner circumferential side of the internal gear 131. This allows for the positioning of the internal gear 131. Furthermore, the housing, internal gear 131, external gear 132, and positioning pin 150 are mutually constrained, closely related, and have a compact structure. Applying lubricant to the mating areas reduces friction and improves service life.

[0068] Furthermore, the locating pin 150 is fitted with a bushing 151, which is positioned and engaged with the inner circumferential side of the internal gear 131.

[0069] like Figure 5 As shown, in one embodiment, the auxiliary handle 100 further includes a reset member 160. One end of the reset member 160 is connected to the housing 110, and the other end is connected to the internal gear 131. The reset member 160 is used to cause the operating component 120 to tend to move along the arc-shaped guide groove 112 in the locking direction, wherein the unlocking direction is opposite to the locking direction. Thus, when the user controls the operating component 120 to move in the unlocking direction to release the rotating shaft 140, after the angle of the camera bracket 200 is adjusted, the user can release the operating component 120. The operating component 120 will then move in the locking direction and automatically reset under the action of the reset member 160. Furthermore, the external gear 132 and the internal gear 131 will also automatically reset, causing the clamping member 134 to clamp the rotating shaft 140 again. In addition, under the action of the reset member 160, the rotating shaft 140 can also be kept in a clamped state in its natural state, which provides high safety.

[0070] Combination Figure 5 and Figure 7 Specifically, the reset member 160 is a spring, which is disposed in the inner cavity 111. The side wall of the housing 110 is provided with a first hole 114 and a second hole 115 spaced apart from each other. One end of the spring passes through the first hole 114 and extends to the outside of the housing 110 and then extends into the interior of the inner cavity 111 through the second hole 115.

[0071] Furthermore, the outer wall of the housing 110 is provided with a groove 116, and the first hole 114 and the second hole 115 are opened on the groove wall of the groove 116. By setting the blocking member in the groove 116, the spring can be blocked, making the auxiliary handle 100 look better.

[0072] like Figure 5 As shown, the internal gear 131 is further provided with a connector 1311, and one end of the spring is connected to the connector 1311. The connector 1311 can be a screw.

[0073] like Figures 1 to 4As shown, in the camera support device of the present invention, the operating component 120 can be operated by hand, that is, the user can push the operating component 120 to move the operating component 120 along the arc-shaped guide groove 112. When the operating component 120 moves along the arc-shaped guide groove 112 under the operation of the user, the operating component 120 can drive the internal gear 131 to rotate, thereby causing the internal gear 131 to drive the external gear 132 to rotate. When the external gear 132 rotates, under the guidance of the guide member 133, the external gear 132 can move along the axial direction of the external gear 132. Specifically, when the operating component 120 moves in the unlocking direction (clockwise), it drives the internal gear 131 and the external gear 132 to rotate clockwise, causing the external gear 132 to move in the first direction under the action of the guide member 133. When the operating component 120 moves in the locking direction (counterclockwise), it drives the internal gear 131 and the external gear 132 to rotate counterclockwise, causing the external gear 132 to move in the second direction under the action of the guide member 133. When the external gear 132 moves in the first direction, it gradually loosens from the clamping member 134; when it moves in the second direction, it gradually tightens against the clamping member 134. When the clamping member 134 is released from the external gear 132, the force exerted by the external gear 132 on the clamping member 134 decreases, the clamping member 134 is released, and the rotating shaft 140 can rotate freely. When the clamping member 134 is pressed against the external gear 132, the external gear 132 applies a force to the clamping member 134, causing the clamping member 134 to clamp the rotating shaft 140, thus restricting the rotation of the rotating shaft 140. When the rotating shaft 140 is released, the user can adjust the angle of the camera bracket 200, thereby adjusting the camera angle. When the rotating shaft 140 is clamped by the clamping member 134, the camera bracket 200 is fixed to the auxiliary handle 100 under the action of the rotating shaft 140, thus ensuring that the auxiliary handle 100 stably supports the camera bracket 200, thereby ensuring stable support of the camera. When the user holds the auxiliary handle 100 of this invention, they only need to use their thumb to control the operation component 120 to release the pivot 140 from the clamp 134, thereby allowing the angle of the camera bracket 200 to be adjusted. Furthermore, while the user holds the auxiliary handle 100 with one hand, the thumb of that hand can control the operation component 120 to release the pivot 140 from the clamp 134, while the other hand can be used to adjust the angle of the camera bracket 200, thereby changing the angle of the camera. This operation is convenient, and this method of adjusting the camera angle does not require the user to bend their arm or wrist, which can improve the problem of soreness that users easily feel when adjusting the camera angle by bending their wrist or arm.In addition, the operating component 120 controls the rotation of the internal gear 131 by making an arc-shaped motion. Therefore, when the user swings his thumb to control the operating component 120, he can still maintain the posture of holding the auxiliary handle 100, reducing the risk of the auxiliary handle 100 falling and ensuring high safety.
