Accordingly, the above terms should not be construed as limiting the present utility model.

Referring to fig. 1 to 5 of the drawings, an adapter according to an embodiment of the present utility model is illustrated, wherein the adapter comprises a main body 1, an adapter 2, an elastic member 3 and a passive member 4, wherein the adapter 2 is mounted on the main body 1, the adapter 2 is configured to be fitted with an optional fitting so that the optional fitting can be detachably mounted on the adapter 2, the elastic member 3 is disposed in a blind hole 100 of the main body 1, the passive member 4 comprises a movable main body 41 and a limiting member 42, wherein a first end 411 of the movable main body 41 is disposed in the blind hole 100 of the main body 1, and the first end 411 of the movable main body 41 abuts against the elastic member 3, and the limiting member 42 extends from a second end 412 of the movable main body 41, and the limiting member 42 is configured to be capable of penetrating from a through hole 20 of the adapter 2, wherein the passive member 4 is configured to be capable of moving axially beyond the limiting member 421 and is configured to limit the end face 421 to the end face 2 when the passive member 4 is disposed to be capable of axially limiting the end 421 and is mounted on the end face 2; when the passive element 4 is driven to move axially to a release limit position, at least the limit end 421 of the limit element 42 is hidden in the through hole 20 of the adapter 2, so that the limit end 421 of the limit element 42 is disengaged from the optional accessory. Accordingly, the adapter 2 is provided to allow the optional fitting to be detachably mounted thereon. It can be understood that when the driven member 4 is driven to move to the limit position along the axial direction, the switching device is controlled to be in a corresponding limit state; when the driven member 4 is driven to move to the unlocking position along the axial direction, the switching device is in the unlocking state. Accordingly, when the adaptor is in the limit state, the limit end 421 of the limit piece 42 penetrates through the through hole 20 of the adaptor 2 and protrudes out of the end face 21 of the adaptor 2, so as to limit the optional accessory, when the adaptor is in the release limit state, the limit end 421 of the limit piece 42 is completely accommodated in the through hole 20 of the adaptor 2, and the limit end 421 does not protrude out of the end face 21 of the adaptor 2 any more, so that the optional accessory is prevented from being scratched by the limit end 421 in the process of mounting and dismounting. Illustratively, the adapter device of the present utility model may be used for a camera, the reference mirror of which is an optional accessory, adapted to be mounted on said adapter part 2.

As shown in fig. 4A and 4B of the drawings, when the adaptor of the present utility model is assembled, the first end 411 of the movable body 41 of the passive element 4 is inserted into the blind hole 100 of the body 1, and the stopper 42 of the passive element 4 is inserted into the through hole 20 of the adaptor 2, so that the blind hole 100 and the wall of the through hole 20 can restrain the passive element 4 during the movement of the passive element 4, so that the passive element 4 can be driven to reciprocate along the axial direction. It will be appreciated that the axial direction may be considered as the direction of extension of the central axis of the blind hole 100, and may also be considered as the direction of extension of the central axis of the through hole 20. In other words, the central axis of the blind hole 100 is parallel to the central axis of the through hole 20.

As shown in fig. 4A of the drawings, when the adaptor of the present utility model is assembled and in an initial state not acted by an external force, the elastic member 3 is compressed appropriately to apply an appropriate force on the passive member 4, so as to drive the passive member 4 to move axially to a limit position and make the limit end 421 of the limit member 42 pass through the through hole 20 of the adaptor 2 and protrude from the end face 21 of the adaptor 2. Preferably, the width of the second end 412 of the movable body 41 is larger than the inner diameter of the through hole 20 of the adapter part 2, so that when the limiting end 421 of the limiting member 42 passes out of the through hole 20 of the adapter part 2 and protrudes out of the end surface 21 of the adapter part 2, the second end 412 of the movable body 41 of the passive member 4 can abut against the adapter part 2 under the action of the force exerted on the passive member 4 by the elastic member 3, so as to ensure that the adapter device can stably maintain the limiting state when no external force acts. In other words, the initial state of the switching device, that is, the state that is not acted by the external force, is the limit state, and when the switching device is in the limit state, the elastic member 3 is compressed appropriately, and the second end 412 of the movable body 41 of the passive member 4 abuts against the switching portion 2, so as to ensure that the limit end 421 of the limit member 42 of the passive member 4 can pass through the through hole 20 of the switching portion 2 and protrude from the end face 21 of the switching portion 2. As shown in fig. 4B of the drawings, when the switching device of the present utility model is subjected to an external force, so that the driven member 4 is driven to move in a direction approaching the main body 1 and away from the switching portion 2, the limiting end 421 of the limiting member 42 of the driven member 4 is retracted into the through hole 20 of the switching portion 2 until being completely accommodated in the through hole 20 of the switching portion 2, thereby causing the switching device to be in the unlocking state, at this time, the second end 412 of the movable main body 41 of the driven member 4 is separated from the switching portion 2, a gap is formed between the second end 412 of the movable main body 41 and the switching portion 2, the driven member 4 is driven to move axially to the unlocking position, and the elastic member 3 is further compressed. Once the external force applied to the switching device is removed, the passive component 4 is reset under the thrust action of the elastic component 3, so that the passive component 4 is driven to axially move towards the direction approaching to the switching part 2 and away from the main body part 1, and the switching device is reset from the unlocking limit state to the limit state.

It should be noted that the elastic member 3 may be implemented as a compression spring, a torsion spring, a gas compression spring, or the like, and the specific type thereof should not be considered as limiting the scope of the present utility model, and any specific embodiment of the elastic member 3 capable of implementing the above-mentioned functions of the elastic member 3 is included in the scope of the present utility model.

Accordingly, the adaptor device of the present utility model has been primarily explained, which has been capable of achieving some of the advantages of the present utility model, such as directly applying an external force to the passive component 4 to drive the passive component 4 to move in a direction approaching the main body 1 and moving away from the adaptor 2, so that the limiting end 421 of the limiting component 42 of the passive component 4 is retracted into the through hole 20 of the adaptor 2. It will be appreciated that the elastic element 3 and the passive element 4 are both elements or components for constructing the limit structure of the adapter device.

As shown in fig. 1 to 5, in order to more conveniently and reliably drive the driven element 4, the switching device further comprises an abutment element 5, a reversing drive element 6 and a pressing control element 7, wherein the abutment element 5 is arranged on the movable body 41 of the driven element 4 so that the driven element 4 can drive the abutment element 5 to move axially and the abutment element 5 can drive the driven element 4 to move axially, wherein the reversing drive element 6 comprises an adapting portion 61 and an adapting portion 62, wherein the adapting portion 61 of the reversing drive element 6 is inserted into an adapting groove 701 of the pressing control element 7 so that the reversing drive element 6 can drive the pressing control element 7 to move radially and the pressing control element 7 can drive the reversing drive element 6 to move radially, wherein the abutment element 62 of the reversing drive element 6 is radially and partially received in the receiving groove 4 to move axially, wherein the abutment element 621 is arranged to move the abutment element 5 and the reversing control element 6 to move radially and the reversing control element 7 to stop the abutment element 1 from moving radially and the abutment element 1, wherein the abutment element 621 is arranged to move the abutment element 5 and the reversing control element 7 to move radially and the reversing control element 7 to stop the abutment element 1, wherein the limit groove 10 of the main body part 1 has a proper depth, the limit groove 10 of the main body part 1 extends along the axial direction, so that the pressing control piece 7 can be limited to move radially when being stressed, and the pressing control piece 7 is suitable to be driven to reciprocate along the radial direction. Further, the pressing control member 7 is further provided with a avoiding groove 702, wherein the passive member 4 passes through the avoiding groove 702 of the pressing control member 7, so that the axial movement of the passive member 4 and the radial movement of the pressing control member 7 are prevented from interfering with each other, the passive member 4 is prevented from blocking the radial movement of the pressing control member 7, and the pressing control member 7 is also prevented from blocking the axial movement of the passive member 4.

As shown in fig. 1 to 5, the pressing control member 7 of the switching device of the present utility model includes a pressing portion 71 and a base portion 72, wherein the pressing portion 71 extends from the base portion 72, the pressing portion 71 can pass through the opening 101 of the limiting slot 10 and protrude from the main body portion 1 of the switching device, and the base portion 72 is completely accommodated in the limiting slot 10 of the main body portion 1. As shown in fig. 4A, when the switching device is assembled and in an initial state of no external force, the elastic member 3 is compressed appropriately and applies a certain pushing force to the passive member 4 so that the passive member 4 and the abutment member 5 have a tendency to move in a direction approaching the switching portion 2, thereby causing the abutment member 5 to abut against the abutment surface 621 of the abutment portion 62 of the reversing driving member 6 so that the reversing driving member 6 and the pressing control member 7 have a tendency to move in a direction away from the groove bottom wall 102 of the limiting groove 10, so as to ensure that the pressing portion 71 of the pressing control member 7 can pass through the opening 101 of the limiting groove 10 and protrude from the main body portion 1 of the switching device. At this time, the switching device is in the limiting state, and the limiting end 421 of the limiting member 42 of the driven member 4 passes through the through hole 20 of the switching portion 2 and protrudes out of the end face 21 of the switching portion 2.

As shown in fig. 1 to 5, in order to prevent the base portion 72 of the pressing control member 7 from coming out of the limit groove 10 of the main body portion 1, the main body portion 1 is further provided with a groove top wall 103 of the limit groove 10. It will be appreciated that in some embodiments of the present utility model, when the switching device is in the limit state, the base portion 72 of the pressing control member 7 abuts against the groove top wall 103 of the limit groove 10, at this time, the passive member 4 cannot move in a direction approaching the switching portion 2 of the switching device, and the second end portion 412 of the movable body 41 of the passive member 4 does not need to abut against the switching portion 2. In other embodiments of the utility model, when the adapter device is in the limit state, the base portion 72 of the pressing control member 7 abuts against the groove top wall 103 of the limit groove 10, and at the same time, the second end portion 412 of the movable body 41 of the passive member 4 abuts against the adapter portion 2, so that the mutual engagement of the respective elements or components of the adapter device is more reliable and stable.

Once the external force applied to the pressing portion 71 of the pressing control member 7 is removed, the passive member 4 resets under the pushing force of the elastic member 3, so as to drive the abutting member 5, the reversing driving member 6 and the pressing control member 7 to reset, so that the switching device resets from the release limit state to the limit state.

It will be appreciated that the pressing control member 7 moves along the radial direction when being pressed, the radial movement of the pressing control member 7 is converted into the axial movement of the corresponding part of the limiting structure of the switching device by the reversing driving member 6, so that the switching device can be switched from the limiting state to the de-limiting state in a manner of pressing the pressing control member 7, when the acting force pressing the pressing control member 7 is removed, the elastic member 3 drives the driven member 4 to move axially, the driven member 4 drives the abutting member 5 to move axially, and the axial movement of the corresponding part of the limiting structure is converted into the radial movement of the reversing driving member 6 by the reversing driving member 6, so as to drive the pressing control member 7 to move radially to reset, so that the switching device can be switched from the de-limiting state to the limiting state automatically when the pressing acting force is removed. It will also be appreciated that the elastic element 3, the passive element 4 and the abutment element 5 are all elements or components for constructing a limit structure of the adapter device.
