The utility model aims to overcome the defects of the prior art and provides a handle self-locking device.

The utility model is realized by the following technical scheme:

the utility model provides a handle self-locking device, includes upper side plate, lower side plate, fixed axle, lantern ring, clip, handle, screw rod and torsional spring, is connected through the fixed axle between the center of upper side plate and lower side plate, fixed axle and lower side plate between fixed axle and the upper side plate rotate to be connected, the equipartition has the round locking hole on the lower side plate, it has the lantern ring mounting hole to open on the upper side plate, the round locking hole be located the upper side plate and rotate round the rotation orbit of lantern ring mounting hole under when the fixed axle, lantern ring fixed mounting in the lantern ring mounting hole, the upper and lower end of lantern ring stretches out upper and lower surface of upper side plate respectively, be equipped with upper and lower apron respectively at the upper and lower end of lantern ring, all open the centre bore that supplies the screw rod to pass at upper and lower apron center, the upper and lower end of screw rod wear out the lantern ring respectively, be equipped with the nut in the lower part of screw rod, the torsional spring cover in the lower part of screw rod, and be located between lower apron and the nut, the clip be n style of blocks, two lower ends of clip all be the arc, the clip is located the cross axle, the clip is located the upper cover, the upper end of lantern ring is located the radial, the clip is located at the upper end of clip, and the handle has the both ends of clip, and the top of clip is connected at the pinhole.

The upper cover plate is provided with wedge-shaped grooves matched with the two lower ends of the clip.

The upper side plate and the lower side plate are circular plates.

The utility model has the advantages that: when the lifting mechanism of the tea carding machine is regulated by the handle, the handle is prevented from rotating under the influence of human or vibration of the carding machine, the handle can be locked, so that the tea carding machine is stable and reliable, the inclination angle of the carding machine can be flexibly and real-timely regulated by regulating the rotation of the handle according to the actual condition of tea carding, and the tea carding machine can be regulated in a shutdown state and can also be regulated in the carding process of tea, so that a better carding effect can be obtained.
