This utility model discloses a fence gate locking structure. The key technical features include a fence frame and a gate body. One end of the gate body is hinged to the fence frame, and a locking structure is provided between the other end and the fence frame. The locking structure includes a rotating handle and a limiting plate. The rotating handle is movably mounted on the fence frame, and the limiting plate protrudes from the fence frame on the side corresponding to the gate body. Rotating the rotating handle towards the gate body clamps and locks the gate body between the rotating handle and the limiting plate. This utility model offers high safety, effectively preventing children from opening the locking structure while playing.

The utility model discloses a kind of perpendicularity detection devices of transmission shaft, it is related to transmission shaft detection technical field, including first mounting bracket, adjusting mechanism is installed in first mounting bracket inside, the utility model, through the cooperation track structure of three positioning blocks of annular arrangement, realize the multi-point synchronous locking and positioning of transmission shaft, positioning block is evenly distributed in track inside, track is rotated by external handle driving gear system, in the process of rotation, cam groove structure inside track guides positioning block to contract along radial direction synchronously, complete transmission shaft equidistant surrounding type lateral locking, effectively prevent shaking and skew, ensure detection accuracy and repeatability, simultaneously, by the pre-tightening force of spring extruding block and lifting rod down pressure, carry out constant pressure to transmission shaft top, to further improve vertical stability, realize all-around stable positioning and locking in three-dimensional direction, guarantee the stability and reliability in detection process.
