An adjustment component 4 is provided in the middle of the lens barrel 1. The middle of the adjustment component 4 is connected to the front and rear sides of the spherical lens 3.

[0026] The adjustment assembly 4 includes an adjustment sleeve 41 that is slidably fitted onto the outside of the lens barrel 1. A linkage adjustment sleeve 42 is slidably fitted inside the adjustment sleeve 41. A linkage assembly 43 is threadedly fitted inside the linkage adjustment sleeve 42. The front and rear sides of the inner cavity of the linkage assembly 43 extend into the interior of the lens barrel 1 and are connected to the front and rear sides of the outer surface of the spherical lens 3. Two friction pads 44 that fit together are connected to one side of the adjustment sleeve 41. A positioning spring 45 is connected to the other side of the adjustment sleeve 41. The opposite sides of the two friction pads 44 are fixedly connected to the lens barrel 1 and the adjustment sleeve 41, respectively. Under the elastic restoring force of the two positioning springs 45, the adjustment sleeve 41 pushes the two friction pads 44 to fit tightly together. Thus, under the restriction of the lens barrel body 11 and the two friction pads 44, the accidental rotation of the anti-slip sleeve 411 is effectively avoided. This also prevents the accidental rotation of the linkage adjustment sleeve 42 and the linkage assembly 43, thereby preventing the position of the spherical lens 3 from changing unexpectedly after adjustment.

[0029] As shown in the figure, Figures 2 to 4 the linkage adjusting sleeve 42 is threadedly sleeved on the outer surface of the linkage ring 431, the axial length of the linkage adjusting sleeve 42 and the axial length of the limiting clamping groove 13 are the same as the axial length of the sliding groove 12, and the axial length of the linkage ring 431 and the linkage sliding block 432 is smaller than the axial length of the limiting clamping groove 13.

[0030] As shown in the figure, Figure 2 and Figure 5 the adjusting sleeve 41 comprises an anti-skid rotating sleeve 411 movably sleeved in the sliding groove 12, the anti-skid rotating sleeve 411 is movably sleeved in the sliding groove 12, the inside of the anti-skid rotating sleeve 411 is provided with a protective sleeve 413 away from the friction plate 44, the inside of the anti-skid rotating sleeve 411 is provided with a linkage sliding cavity 412 close to the friction plate 44, the inside of the linkage sliding cavity 412 and the outer surface of the linkage adjusting sleeve 42 are polygonal and matched with each other, the linkage sliding cavity 412 is slidingly sleeved on the outer surface of the linkage adjusting sleeve 42, and the protective sleeve 413 is movably sleeved on the outer surface of the lens barrel body 11; due to the arrangement of the linkage sliding cavity 412, the rotating anti-skid rotating sleeve 411 can drive the linkage adjusting sleeve 42 to rotate through the linkage sliding cavity 412, and the arrangement of the protective sleeve 413 can ensure that the anti-skid rotating sleeve 411 is stably sleeved on the lens barrel 1, and the positioning spring 45 can abut against the adjusting sleeve 41.

[0031] As shown in the figure, Figure 2 and Figure 5As shown, the positioning spring 45 is arranged inside the linkage adjusting sleeve 42 and the protective sleeve 413, both ends of the positioning spring 45 are connected with a movable sleeve which is sleeved inside the protective sleeve 413, one end of the positioning spring 45 abuts against one end of the sliding groove 12 away from the friction plate 44 through the corresponding resistance ring, and the other end of the positioning spring 45 abuts against one end of the protective sleeve 413 close to the friction plate 44 through the corresponding resistance ring; due to the arrangement of the resistance ring, it is ensured that both ends of the positioning spring 45 can be compressed between the sliding groove 12 and the protective sleeve 413, and the situation that the positioning spring 45 is twisted when the adjusting sleeve 41 rotates can be avoided.

[0035] After the anti-skid rotating sleeve 411 is loosened, the anti-skid rotating sleeve 411 can be pushed to make the two friction plates 44 at the end of the anti-skid rotating sleeve 411 close to each other again under the action of the elastic recovery force of the positioning spring 45, so that the accidental rotation of the adjusting sleeve 41 is avoided.
