Detailed Description
In order to make the objects, technical solutions, design methods, and advantages of the present invention more apparent, the present invention will be further described in detail by specific embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1-2, the present invention provides a manual locking device for a rotating shaft of a portable antenna, which includes an auxiliary member 6 and a fixing member 7, wherein the auxiliary member 6 is provided with a through hole, the rotating shaft 5 is disposed in the through hole, and one side of the rotating shaft 5 is axially connected to the portable antenna for adjusting a pitch angle of the portable antenna; its characterized in that, one side that portable antenna was kept away from to auxiliary member 6 is provided with latch segment 1, one side that portable antenna was kept away from to rotation axis 5 is provided with Z shape lever 3, the one end of latch segment 1 with auxiliary member 6 is connected, the other end with the upper end of Z shape lever 3 is connected, the lower extreme of Z shape lever 3 is connected with screw rod 2, mounting 7 sets up threaded hole, screw rod 2 runs through the screw hole, screw rod 2 is kept away from the one end of Z shape lever 3 is provided with rotatory handle 8, and in this embodiment, rotatory handle 8 is the five-star handle.
