[0076] By moving the adjustment seat 2 relative to the through hole 1c along the third direction Z, the adjustment seat 2 drives the lens 6 to move along the third direction Z, thereby realizing the adjustment of the position of the lens 6 along the third direction Z. Combined with the above-mentioned adjustment component 3, the lens 6 can move relative to the fixed seat 1 along the first direction X, the second direction Y and the third direction Z; when the lens 6 moves to a preset position along the third direction Z, the adjustment seat 2 is locked to the locking component 4, thereby realizing the fixation of the lens 6 along the third direction Z.

[0077] like Figure 3 As shown, in one embodiment, the locking assembly 4 includes a connecting member 41, which can be connected to or disconnected from the fixing seat 1; the adjusting seat 2 is connected to the connecting member 41 and can move along the third direction Z relative to the connecting member 41.

[0078] By setting a connecting member 41, the connecting member 41 can be connected to or disconnected from the fixed seat 1, the adjusting seat 2 is connected to the connecting member 41, and the adjusting seat 2 is connected to the fixed seat 1 via the connecting member 41. By moving the adjusting seat 2 relative to the connecting member 41 along the third direction Z, the adjusting seat 2 can be moved relative to the locking assembly 4 along the third direction Z.

[0080] When the connecting member 41 needs to be fixed to the fixing seat 1, the first locking surface and the second locking surface are controlled to fit the fixing seat 1. At this time, the first locking surface and the second locking surface cannot move relative to the fixing seat 1 along the third direction Z, thereby achieving the fixation of the connecting member 41 relative to the fixing seat 1.

[0081] It should be understood that the first connection portion 411 and the second connection portion 412 can be connected by means of snaps, threads, screws, etc.

[0082] like Figure 2 and Figure 3 As shown, in one embodiment, the first connecting portion 411 includes a first circular ring 4111, a second circular ring 4112 and a third circular ring 4113 with gradually increasing diameters and coaxially arranged, the first circular ring 4111, the second circular ring 4112 and the third circular ring 4113 are sleeved on the adjustment seat 2, the first circular ring 4111 is threadedly connected to the adjustment seat 2, the second circular ring 4112 is provided with a plurality of threaded holes that can be threadedly connected to the first adjustment member 31 and the second adjustment member 32, the plurality of threaded holes are respectively arranged along the first direction X and the second direction Y, the third circular ring 4113 has a first locking surface that can abut against one side of the fixed seat 1, the second connecting portion 412 is sleeved on the first circular ring 4111 and threadedly connected to the first circular ring 4111, and the second connecting portion 412 has a second locking surface that can abut against the other side of the fixed seat 1. Specifically, the second circular ring 4112 is arranged in the through hole 1c, the third circular ring 4113 and the second connecting portion 412 are arranged on both sides of the fixed seat 1 and abut against the fixed seat 1.

The third adjusting member 33 is grounded with the second ring 4112 and abuts against the adjusting seat 2 via the second ring 4112. When it is necessary to connect the first connecting portion 411 and the second connecting portion 412 to the fixed seat 1, the second connecting portion 412 is rotated to move the second connecting portion 412 toward the direction approaching the third ring 4113 until the third ring 4113 and the second connecting portion 412 clamp the two sides of the fixed seat 1. At this time, the connecting member 41 is fixed relative to the fixed seat 1. At this time, by rotating the adjusting seat 2, the adjusting seat 2 is threadedly connected with the first ring 4111, so that the adjusting seat 2 can move relative to the connecting member 41 along the third direction Z.

[0086] It should be understood that the locking member 42 can limit the movement of the adjustment seat 2 relative to the first connection portion 411 and the second connection portion 412 by abutting against the first connection portion 411 and / or the second connection portion 412 .

[0087] Furthermore, the locking piece 42 is threadedly connected to the adjustment seat 2 and can abut against or disengage from the first ring 4111. When the adjustment seat 2 needs to be locked, the locking piece 42 is rotated and slides in a direction close to the first ring 4111 until the locking piece 42 abuts against the first ring 4111. At this time, the abutment between the locking piece 42 and the first ring 4111 can limit the rotation of the adjustment seat 2 relative to the locking piece 42 and the first ring 4111, thereby achieving the locking of the adjustment seat 2.
