When the second clamping member 3 rotates about the rotating shaft 2 toward the first clamping member 1 until it abuts against the first clamping member 1, the clamping slot 20 is closed.

[0047] The locking member 4 is a component used to lock and unlock the first clamping member 1 and the second clamping member 3; the locking member 4 is used to lock the first clamping member 1 and the second clamping member 3 when the clamping groove 20 is closed, so that the clamping groove 20 remains in a closed state; the locking member 4 is used to unlock the first clamping member 1 and the second clamping member 3, so that the clamping groove 20 can be transformed into an open state.

[0048] By adopting the above technical solution, the locking Bowens bayonet mechanism 100 of this embodiment can improve the stability of the accessory when it is fixed to the Bowens bayonet 30 of the lamp, so that the lamp and the accessory are located at the same center, avoiding affecting the light parameters of the lamp.

Therefore, the avoidance groove 51 is set corresponding to the position of the docking protrusion 101, thereby achieving avoidance of the docking protrusion 101.

[0054] By adopting the above technical solution, the matching degree between the avoidance groove 51 and the accessory joint 10 is improved.

[0055] In one embodiment, a avoidance structure 5 is provided on the first clamping body 12 , and the avoidance structure 5 forms a avoidance groove 51 ; two avoidance structures 5 are provided on the second clamping body 32 , and each avoidance structure 5 forms a avoidance groove 51 .

[0056] Here, it can be understood that the accessory joint 10 of this embodiment is provided with three docking protrusions 101. In this way, the number of avoidance grooves 51 corresponds to the number of docking protrusions 101, and the three avoidance grooves 51 are evenly arranged along the circumferential direction.

[0058] In one embodiment, the first clamping body 12 and the second clamping body 32 are provided with an abutment structure 6 for abutting against the accessory joint 10 for increasing friction.

[0059] Here, it can be understood that the abutment structure 6 refers to a structure for increasing friction; the abutment structure 6 includes but is not limited to silicone wear-resistant materials. In addition to increasing the friction when in contact with the accessory joint 10, the abutment structure 6 can also prevent the first clamping member 1 and the second clamping member 3 from scratching the accessory joint 10.

[0060] By adopting the above technical solution, the stability of the locking Baorong bayonet mechanism 100 when locking accessories is improved and the possibility of damaging accessories is reduced.

[0062] Here, it can be understood that the parts of the first clamping body 12 used for docking are respectively located at the two ends of the first clamping body 12, one end of which is the first end 121 and the other end is the second end 122; the parts of the second clamping body 32 used for docking are respectively located at the two ends of the second clamping body 32, one end of which is the third end 321 and the other end is the fourth end 322; the first end 121 is provided with a first opening 1211, and the third end 321 is provided with a third opening 3211, the rotating shaft 2 is passed through the first opening 1211 and the third opening 3211, the rotating shaft 2 is limited in the first opening 1211 and the second opening 1221, and the rotating shaft 2 serves as the shaft body for the second clamping member 3 to rotate around the axis; the second end 122 is provided with a second opening 1221, and the fourth end 322 is provided with a fourth opening 3221, the locking member 4 is passed through the second opening 1221 and the fourth opening 3221, so that the locking member 4 can lock the first clamping member 1 and the second clamping member 3.

[0063] By adopting the above technical solution, the first clamping body 12 and the second clamping body 32 are connected through the opposite ends, ensuring that the clamping groove 20 can be maximized within the limited space between the first clamping body 12 and the second clamping body 32. In this way, the clamping groove 20 can clamp large-sized accessory joints 10.

[0064] In one embodiment, the locking member 4 includes a locking nut 41 and a locking screw 42 provided on the locking nut 41, the locking screw 42 is used to pass through the first opening 1211 and the third opening 3211 to threadably connect the first end 121 and the third end 321, and the locking nut 41 is exposed outside the first opening 1211 and the third opening 3211.

[0065] Here, it can be understood that the locking member 4 is threadedly connected to the first end 121 and the third end 321, so that the first clamping member 1 and the second clamping member 3 are threadedly connected; specifically, the locking member 4 includes a locking nut 41 and a locking screw 42, and the locking screw 42 is arranged on the locking nut 41; the locking nut 41 is for the user to hold and rotate, and the locking screw 42 is used to pass through the first opening 1211 and the third opening 3211, and the hole wall of the third opening 3211 is provided with an internal thread, and the internal thread is used to cooperate with the external thread of the locking screw 42.

[0070] Here, it can be understood that when the locking member 4 unlocks the first clamping member 1 and the second clamping member 3, the elastic force of the elastic member 7 drives the first end 121 and the third end 321 to separate. When the first end 121 and the third end 321 separate to a certain extent, the accessory connector 10 can be removed from the clamping groove 20.

[0071] By adopting the above technical solution, the clamping groove 20 is facilitated to expand when the clamping groove 20 is opened, which is conducive to taking out the accessory connector 10.

[0072] In the second aspect, a photographic equipment fixing device is provided, including an accessory, a photographic equipment main body and the above-mentioned locking and Baorong bayonet mount mechanism 100. The accessory can be detachably mounted on the Baorong bayonet mount 30 of the photographic equipment main body, and the locking and Baorong bayonet mount mechanism 100 is used to lock the accessory and the photographic equipment main body.

[0073] The working principle of the photographic equipment fixing device of this embodiment is as follows:

[0074] Place the accessory on the assembled lamp and clip it into the lamp through the Baorong bayonet 30. Slide the first clamp 1 and the second clamp 3 onto the accessory connector 10, and lock the first clamp 1 and the second clamp 3 with the locking member 4, so that the first clamp 1 and the second clamp 3 are linked and evenly contracted, so that the abutment structure 6 contacts and compresses the assembly side wall of the accessory connector 10. By increasing the friction force through compression, the first clamp 1 and the second clamp 3 hold the accessory tightly to prevent it from loosening or falling; at the same time, when the first clamp 1 and the second clamp 3 contract, they contract evenly toward the center, which can effectively avoid large gaps and eccentricity between the accessory connector 10 and the lamp. Ensure that the light output of the lamp and the accessory is concentric and coaxial.

[0075] When removing the accessory, loosen the locking piece 4. Under the elastic force of the elastic piece 7, the first clamping piece 1 and the second clamping piece 3 will expand outward evenly in conjunction with each other, and the abutment structure 6 will gradually separate from the accessory. When the separation is a certain size, the accessory can be directly taken out from the first clamping piece 1 and the second clamping piece 3.

[0076] By adopting the above technical solution, on the basis of having the advantages of the locking and Baorong bayonet mount mechanism 100 of the above embodiment, the photographic equipment fixing device of this embodiment also has the advantage of improving the light output effect of the lamp.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
