Rotary positioning mechanism with target rings convenient to replace and using method

Abstract

The invention discloses a rotary positioning mechanism with target rings convenient to replace and a using method. The positioning mechanism comprises a mounting plate, a threaded rod, a first transmission mechanism, a second transmission mechanism and a locking mechanism. The threaded rod is transversely and rotatably connected to the mounting plate, the first transmission mechanism is connectedto the threaded rod in a threaded mode and movably connected to the second transmission mechanism, and the second transmission mechanism is connected with the locking mechanism. An insert opening usedfor being connected with a fixing mechanism on a target plate is formed in the bottom of the mounting plate, the threaded rod is rotated to enable the first transmission mechanism to drive the secondtransmission mechanism to move, and the second transmission mechanism drives the locking mechanism to lock the fixing mechanism on the target plate. The rotary positioning mechanism with the target rings convenient to replace is compact and reasonable in structure, ingenious in arrangement and convenient to mount, and the target rings can be quickly and efficiently replaced.

Description

technical field [0001] The invention relates to the technical field of tools, in particular to a rotary positioning mechanism and a use method for convenient replacement of target rings. Background technique [0002] The installation structure of the existing target ring (target plate) is complicated, and it is inconvenient to disassemble and replace. [0003] And there are certain problems in the fixing of the target ring (target plate) after replacement, the target ring (target plate) is not firmly fixed and unstable, which affects target shooting training to a certain extent, and has a relatively large negative effect on the achievement and effect of target shooting. It is necessary to improve the related fixing device of the target ring (target plate). Contents of the invention [0004] In view of the above problems, the present invention provides a rotary positioning mechanism and a method of use for easy replacement of target rings, which can effectively solve the p...

AI Technical Summary

Problems solved by technology

[0002] The existing target ring (target plate) has a complex installation structure, and it is inconvenient to disassemble and replace. The operation is cumbersome and complicated when replacing the target ring (target plate), which is not conducive to smooth and efficient target shooting.

[0003] And there are certain problems in the fixation of the target ring (target board) after replacement. The target ring (target board) is not fixed firmly and unstable, which affects target shooting training to a certain extent, and has a relatively large negative effect on the performance and effect of target shooting.
