Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The following describes an embodiment of the present invention based on its overall structure.

An angle-adjustable lens bayonet, as shown in fig. 1-6, comprises a housing 1, a bayonet rotary groove 3 is fixedly connected to the middle part of the housing 1, a bayonet 2 is rotatably connected to the inside of the bayonet rotary groove 3, a toothed ring 4 is fixedly connected to the outer ring of the bayonet 2 at the part rotatably connected with the bayonet rotary groove 3, the toothed ring 4 is provided with a plurality of groups of tooth sockets 5, a plurality of groups of plug grooves 7 are arranged in the bayonet rotary groove 3 and perpendicular to the toothed ring 4, a spring groove 6 is arranged above the plug groove 7, a spring 8 is arranged in the spring groove 6, the spring 8 can provide elastic force for the bouncing of a slip 9, when the limit of the slip 9 is released by a top post 12, the slip 9 is connected in the spring groove 6, a plug 10 is fixedly connected to the bottom end of the slip 9, a top post groove 11 is vertically arranged above the spring groove 6 in the housing 1, the top post 12 is slidably connected in the top post groove 11, a screw 13 is connected to the rear end of the top post 12, the screw 13 extends and is connected with knob 14 to casing 1 is outer, and knob 14 can set up the multiunit, and casing 1 is provided with the scale ring 15 that the diameter is greater than bayonet 2 on the outer wall, the rotatory angle of understanding camera lens that can be convenient through scale ring 15.
