DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figures 1 to 3In the embodiment of the present invention, the micrometer seat locking structure includes a fixed base 1 and a rotating shaft 3. A rotating support seat 2 is integrally formed on the upper side of the fixed base 1. A bottom pressing guide seat 4 is installed on the rotating support seat 2. A mounting hole 404 is provided on the bottom pressing guide seat 4. The bottom pressing guide seat 4 is rotatably connected to the rotating shaft 3, and the rotating shaft 3 is fixedly connected to the rotating support seat 2. The bottom pressing guide seat 4 includes a guide portion 401, a claw 5 integrally formed on the bottom pressing guide seat 4 and located on one side of the guide portion 401, and a locking opening groove 402 opened on the bottom pressing guide seat 4 and located between the claw 5 and the guide portion 401 and passing through the mounting hole 404. A locking screw 8 is provided inside the guide portion 401 and the claw 5, and a claw 5 is provided on the periphery of the locking screw 8 and located on one side of the guide portion 401.

[0018] Among them, an elastic leather pad 6 is glued to one side wall of the clamping claw 5, and a clamping claw 2 7 is movably arranged inside the guide groove 403 on the bottom clamping guide seat 4. A threaded locking hole 701 is provided on the clamping claw 2 7 to cooperate with the thread of the locking screw 8, and a rib plate 702 is also integrally formed on the clamping claw 2 7.

[0019] By adopting the above technical solution, before locking, the clamping claw 1 5 is not subjected to force, and the bottom clamping guide seat 4 can rotate flexibly along the rotating shaft 3. When locking is required, the clamping claw 2 7 can be driven to slide along the guide groove 403 toward the side of the clamping claw 1 5 by rotating the locking screw 8. The micrometer is locked by the cooperation between the clamping claw 1 5 and the clamping claw 2 7. At the same time, the clamping claw 1 5 on the bottom clamping guide seat 4 is subjected to force toward the guide part after being subjected to the force of the clamping claw 2 7, and the locking opening groove 402 is tightened. The mounting hole clamps the rotating shaft to achieve locking of the rotating shaft. The locking of the micrometer and the rotating shaft 3 can be achieved through one locking direction, which is extremely efficient and convenient.

[0020] Among them, a spring 9 is clamped on the outer periphery of the locking screw 8 between the clamping claw 1 5 and the clamping claw 2 7, and a locking handle 10 is fixedly connected to one end of the locking screw 8. The spring 9 can play the role of elastic support to ensure that when there is no force, the clamping claw 1 5 is always at one end of the guide part 401 of the bottom clamping guide seat 4, which is convenient for the placement of the micrometer.

[0021] In this embodiment, an elastic ring 11 is provided on the periphery of the locking screw 8 between the locking handle 10 and the guide portion 401 of the bottom pressing guide seat 4 to provide elastic support and prevent the locking from loosening.

[0022] In this embodiment, there is a movable gap between the guide portion 401 on the bottom clamping guide seat 4 and the clamping claw 5 and the locking screw 8.
