Referring to fig. 4, the connecting member 2 is provided with a limiting hole 22, the size of the limiting hole 22 is adapted to the positioning pin 151, and the positioning pin 151 extends out of the top surface of the mounting seat 11 and is clamped into the limiting hole 22 in the state that the connecting member 2 and the mounting female seat 1 are interlocked, so that locking is realized. When the unlocking is needed, the switch button 152 is pressed to drive the positioning pin 151 to move downwards, so that the positioning pin 151 exits from the limiting hole 22, and the unlocking is realized.

See fig. 3, the inside wall of mount pad 11 is provided with jack catch 112 and stopper 113, see fig. 4, connecting piece 2 is provided with the buckle 21 with jack catch 112 axial interlocking each other, when needing to interlock connecting piece 2 and female mount pad 1, aim at female mount pad mark 16 with the connecting piece mark 25 shown in fig. 1 earlier, insert connecting piece 2 in the middle of female mount pad 1 subsequently, clockwise turning connecting piece 2, touch stopper 113 and stall until buckle 21 of connecting piece 2, the crisscross laminating of buckle 21 of connecting piece 2 and the jack catch 112 of mount pad 11 this moment, connecting piece 2 and mount pad 11 axial interlocking.

In the process of inserting the connecting piece 2 into the mounting female socket 1, the positioning pin 151 directly sinks into the space avoiding 24, and because the depth of the space avoiding 24 is greater than the height of the positioning pin 151 extending out of the mounting female socket 1 in a normal state, and a gap exists between the positioning pin 151 and the space avoiding 24, the space avoiding 24 cannot press the positioning pin 151, so that a user does not need to apply axial force to press the positioning pin 151 in the process of inserting the connecting piece 2 into the mounting female socket 1. When the connecting piece 2 is inserted into the space 24, the fastener 21 of the connecting piece exceeds the jaw 112, the connecting piece 2 is rotated, the positioning pin 151 moves towards the inclined plane 23, in the moving process, a part of the jaw 112 synchronously enters the fastener 21, the preliminary fitting between the jaw and the fastener is realized, thereafter, the connecting piece 2 is continuously rotated, the positioning pin 151 enters the inclined plane 23 and climbs along the inclined plane 23, in the process, the inclined plane 23 slowly presses down the positioning pin 151 until the positioning pin 151 is rotated to align to the limiting hole 22, at the moment, the compressed positioning pin 151 rebounds under the action of the pressure spring 154, and is clamped into the limiting hole 22, and the circumferential direction locking is realized.

Since the latch 112 is already engaged with the latch 21 in a staggered manner when the positioning pin 151 enters the inclined surface 23, the elastic force generated by the compressed spring 154 can be automatically offset by the reaction force generated by the latch 21 during the process of pressing the positioning pin 151 by the inclined surface 23. Thus, in the installation process, a user does not need to apply a thrust to resist the elastic force generated by the compression spring 154, and only needs to provide a transverse rotating force, so that the aim of saving labor is fulfilled.

When the connecting piece 2 needs to be detached, the switch button 152 is pressed down, the positioning pin 151 is made to exit from the limiting hole 22 so as to relieve the locking state, then the connecting piece 2 is rotated anticlockwise, the connecting piece 2 and the mounting seat 11 are made to be separated from each other, and the conversion lens can be taken out quickly.

Further, referring to fig. 3, the circumferential direction outer side of the base 13 is connected with a fixing pin 132 and a matching through hole thereof, the fixing pin 132 is disposed at two ends of a diameter line of the base 13, and the base 13 is positioned on the waterproof lens barrel 3 through the fixing pin 132. Through setting up fixed pin 132, can make base 13 not only can adapt to the connection of different thickness, tightly decide effectually, can make its location installation that adapts to different hole sites moreover, including various through-holes, half through-hole and blind hole spare part etc. the application range is wide.

In actual underwater photography or shooting, because the time for shooting objects is short, if the conversion lens needs to be replaced, the object cannot be taken ashore and then launched, which delays the time, the conversion lens often needs to be replaced directly underwater, but when underwater replacement is carried out, the gap between the conversion lens and the waterproof lens barrel 3 cannot be avoided from being launched, so that the shooting effect is influenced. In order to solve the problem, as shown in fig. 3, the scheme is that a groove is formed on the mounting seat 11 to form a water inlet channel 114, and in and after the underwater replacement process, water can enter a gap between the waterproof lens barrel 3 and the conversion lens through the water inlet channel 114 so as to completely fill the gap, at the moment, through setting a light path system and lens parameters inside the conversion lens, the shooting chromatic aberration influence caused by the water existing between the waterproof lens barrel 3 and the conversion lens is corrected, so that a user can replace the conversion lens underwater without influencing the later shooting effect, and the underwater replacement is realized. It should be noted that how to set the optical path system and lens parameters inside the conversion lens to correct the effect of chromatic aberration caused by water existing between the waterproof lens barrel 3 and the conversion lens is not included in the scope of the present disclosure, so the present disclosure is not expanded.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
