In order to enable people to adjust the camera under different shooting angles without adjusting the hand-held posture and improve the comfort level of people during shooting, the utility model provides an adjusting handle 100, wherein the adjusting handle 100 has multi-angle adjusting capability. As shown in fig. 1 to 8, in the present application, the present adjustment handle 100 includes a rotation shaft 110 and a hand-holding portion 120.

As shown in fig. 1, 5 and 6, the rotating shaft 110 includes a first end 111 and a second end 112, the first end 111 is connected to the handheld portion 120, and the second end 112 is connected to the handheld portion 120, and in use, the rotating shaft 110 is matched with the transmission assembly 122, so that the camera can rotate relative to the handheld portion 120 about a central axis of the rotating shaft 110.

As shown in fig. 1, the transmission assembly 122 includes a first gear 1221, a second gear 1222, and a locking portion 1224. The central axis of the first gear 1221 coincides with the axis of the rotating shaft 110, the first gear 1221 is connected to the first end 111, the rotating shaft 110 can drive the first gear 1221 to rotate, and the first gear 1221 can also drive the rotating shaft 110 to rotate. The central axis of the second gear 1222 is parallel to the central axis of the first gear 1221, and the second gear 1222 is directly or indirectly meshed with the first gear 1221. The first gear 1221 is capable of rotating the second gear 1222, and the second gear 1222 has a first state and a second state, and the second gear 1222 is capable of translating in a direction parallel to its central axis, thereby switching between the first and second states. As shown in fig. 2, in the first state, the second gear 1222 is connected to the locking portion 1224, and at this time the locking portion 1224 can restrict rotation of the second gear 1222, i.e., the camera can be limited to a certain angle. As shown in fig. 3, in the second state, the second gear 1222 is separated from the locking portion 1224, so that the first gear 1221 can drive the second gear 1222 to rotate, that is, the rotation shaft 110 can drive the camera to rotate to a proper position. In use, since the adjustment handle 100 has the rotation shaft 110, people do not need to change the hand-held posture during the adjustment process, and only need to adjust the state of the second gear 1222 according to the requirement, so that the camera can be adjusted to a proper angle and fixed.

As shown in fig. 4, in various embodiments, the transmission may be provided with various power components in order to facilitate the switching of the second gear 1222 between the first and second states. Specifically, an electromagnetic valve may be disposed on the hand-held portion 120, and a magnetic attraction portion is disposed on the second gear 1222 or the second gear 1222 is entirely used as an armature, so that the second gear 1222 can be controlled to switch between the first state and the second state by controlling the on-off of the electromagnetic valve during use. In various embodiments, a control button 1225 may also be provided on the handpiece 120 to cause the second gear 1222 to switch between the first state and the second state.

As shown in fig. 4, as a preferred embodiment, the transmission assembly 122 includes a control button 1225 and an elastic portion 1226, the control button 1225 is disposed through the second gear 1222 and the elastic portion 1226 along a central axis of the second gear 1222, the elastic portion 1226 is disposed on a side of the second gear 1222 near the locking portion 1224, the control button 1225 has an abutting portion 1227, and the abutting portion 1227 is disposed on a side of the second gear 1222 away from the elastic portion 1226. In use, the control button 1225 is pushed along the central axis of the second gear 1222, the abutting portion 1227 abuts against the second gear 1222, and the second gear 1222 is pushed to translate from the abutting portion 1227 to the elastic portion 1226, so that the second gear 1222 can be switched from the first state connected to the locking portion 1224 to the second state separated from the locking portion 1224, and the camera can be adjusted to a desired angle at this time. After the camera is adjusted to a desired angle, since the elastic portion 1226 is compressed under the action of the second gear 1222 at this time, the external force applied to the adjusting knob is removed, and the second gear 1222 returns to the first state from the second state under the action of the elastic portion 1226, so that the locking portion 1224 can limit the state of the second gear 1222, it can be understood that when the second gear 1222 is in the first state, the rotation of the first gear 1221 directly or indirectly engaged with the second gear 1222 will be limited, and likewise, the rotation of the rotation shaft 110 connected to the first gear 1221 and the rotation of the camera connected to the rotation shaft 110 will be limited.

It should be noted that, in different embodiments, the elastic member may be any member capable of switching the second gear 1222 between the first state and the second state, such as a spring, an elastic sheet, and a rubber belt. The elastic portion 1226 may be disposed on a side of the second gear 1222 facing away from the abutting portion 1227, or may be disposed on a side of the second gear 1222 facing toward the clamping portion. The elastic portion 1226 may be disposed around the control button 1225, or may be disposed in any other form capable of meeting the use requirement of the second gear 1222, which is not particularly limited in this embodiment.

As shown in fig. 4, in various embodiments, to enable the locking portion 1224 to limit rotation of the second gear 1222 in the first state, the locking portion 1224 may be configured as any suitable component, such as a fastener, rack, or worm 12241, worm gear 12242 assembly. As a preferred embodiment, the locking portion 1224 includes a worm 12241 and a worm gear 12242, the worm gear 12242 being meshed with the worm 12241, the worm gear 12242 being configured to be meshed with the second gear 1222. In the locking portion 1224 formed by the worm 12241 and the worm wheel 12242, the mechanism has self-locking properties when the lead angle of the worm 12241 is smaller than the equivalent friction angle between the meshing wheel teeth, i.e. in the worm 12241 and worm wheel 12242 mechanism, only the worm wheel 12242 can be driven by the worm 12241 and the worm 12241 cannot be driven by the worm wheel 12222. Thus, in the first state, the second gear 1222 is connected to the worm gear 12242, and since the worm gear 12242 cannot rotate the worm 12241, the worm gear 12242 meshes with the second gear 1222, and the worm gear 12242 restricts the rotation of the second gear 1222, the camera does not rotate the rotation shaft 110. In the second state, the second gear 1222 is separated from the worm gear 12242, where the second gear 1222 is not limited in rotation by the worm gear 12242, and the first gear 1221 is able to drive the second gear 1222 to rotate, i.e., where the rotation of the camera is no longer limited.

As shown in fig. 5 and 6, in various embodiments, the worm gear 12242 may be any gear capable of meeting the requirements, and in order to have different gear ratios, the worm gear 12242 may be configured as any meeting gear set having different numbers of teeth, and the second gear 1222 may be connected to any of the gears when the second gear 1222 is in the first state. It can be appreciated that in the present embodiment, the worm gear 12242 is configured such that when the duplex gear is disposed in the first state of the second gear 1222, the worm 12241 drives the worm gear 12242 to rotate, and the worm gear 12242 drives the second gear 1222 and the first gear 1221 to rotate, and the first gear 1221 further drives the rotation shaft 110 to rotate, and finally the rotation shaft 110 drives the camera to rotate, that is, when the second gear 1222 is disposed in the first state, the worm 12241 is rotated to achieve fine adjustment of the rotation angle of the camera. In the first state, the second gear 1222 is engaged with different sub-gears in the dual gear, so that the handheld portion 120 can output different transmission ratios.

In this application, the first gear 1221 and the second gear 1222 in the transmission assembly 122 may be directly engaged or indirectly engaged, that is, other transmission components may be disposed between the first gear 1221 and the second gear 1222 when the first gear 1221 and the second gear 1222 are indirectly engaged according to different transmission requirements. As shown in fig. 2, in this embodiment, in order to reasonably set the thicknesses of the first gear 1221, the second gear 1222 and the third gear 1223 and facilitate the switching of the second gear 1222 between the first state and the second state, the transmission assembly 122 further includes a third gear 1223, where the third gear 1223 is meshed with the first gear 1221 and the second gear 1222, respectively, and ensure that the second gear 1222 is always meshed with the third gear 1223 during the switching state, and the sum of the thickness of the third gear 1223 and the thickness of the second gear 1222 is greater than the stroke of the switching state of the second gear 1222.

When the camera is used for shooting, if a large amount of additional equipment is assembled on the camera, the convenience of adjusting the angle of the camera can be greatly reduced under the influence of the volume and the weight of the additional equipment. As shown in fig. 8, in order to improve convenience in photographing of a camera, the adjustment handle 100 of the present application includes a boot groove assembly 130, and the boot groove assembly 130 is coupled to the outside of the housing 121. The boot groove is a clamping groove for connecting various external accessories of the camera, and is divided into a hot boot groove and a cold boot groove. Additional devices often used in photography, such as flashlights, flash, microphones, etc., are connected to the camera through a hot shoe. The hot shoe groove typically has contacts. Taking a flash as an example, the contact may transmit photometric information on the flash to the camera, which may also transmit information and energy to the flash to be output, that is, the contact has the function of transmitting information and energy. In contrast, the cold boot groove has no contacts, only as a mounting base for the add-on device. In various embodiments, the boot groove is provided on the adjustment handle 100, so that the rotation adjustment difficulty of the camera can be reduced while the use effect of the camera is ensured. It is understood that the adjustment handle 100 may be provided with either one of a hot boot groove and a cold boot groove, or may be provided with both the hot boot groove and the cold boot groove. To accomplish different functions of the assembled accessory, the boot strap assembly 130 may also include connection components for data and energy transfer between different devices.

In various embodiments, as shown in fig. 7, to improve the stability of the connection between the shaft 110 and the handle 120, the adjustment handle 100 may be provided with a release-preventing cover 140. In a specific use process, the rotating shaft 110 may be connected to the anti-drop cover 140 by bolts or the like. In this embodiment, the rotating shaft 110 is disposed through the housing 121, the adjustment handle 100 has a release-preventing cover 140, the release-preventing cover 140 is connected to the rotating shaft 110, and the release-preventing cover 140 abuts against the outer side surface of the housing 121. That is, the anti-falling cover plate 140 makes the rotating shaft 110 abut against the housing 121, so as to improve the connection stability of the rotating shaft 110 and the handheld portion 120.

In various embodiments, as shown in fig. 9, the adjustment handle 100 may also include a camera rabbit cage 150 for ease of connection with the camera. In this embodiment, the camera rabbit cage 150 has a side frame abutting against the camera hand-holding portion 120, and the second end 112 of the rotating shaft 110 is connected to the side frame. When in use, the rotating shaft 110 is connected to the side frame of the camera rabbit cage 150 at one side of the camera handheld portion 120, so that the camera can rotate along with the camera rabbit cage 150 by taking the central axis of the rotating shaft 110 as an axis.

As shown in fig. 9, correspondingly, the embodiment of the present utility model further provides a camera 200, and the camera 200 includes the adjustment handle 100 in any of the above embodiments. Specifically, in the present embodiment, the adjustment handle 100 is connected to one side of the camera hand-held portion 120 or to the opposite side of the camera from the camera hand-held portion 120.
