The position adjustment mechanism with position limiting protection and timely hovering function according to claim 4, wherein the latch assembly II (25) and the latch assembly III (26) are structurally the same and each include: the handle (18), the shaft sleeve (19), the bolt (20), the pressure spring (21) and the screw (22);
the shaft sleeve (19) is of a cavity structure with an opening at one end and a through hole at the other end, a shaft shoulder is arranged on the periphery of the shaft sleeve, the handle (18) is of a cavity structure with an opening at one end and an internal threaded hole at the other end, the opening end of the handle (18) is in sliding fit with the periphery of the shaft sleeve (19), and the shaft shoulder on the shaft sleeve (19) plays a role in limiting the handle (18); the bolt (20) is of a stepped shaft-shaped structure, and the small end of the bolt is provided with an external thread, passes through a through hole at the end part of the shaft sleeve (19) and is in threaded connection with an internal thread hole at the end part of the handle (18); a pressure spring (21) is sleeved on the bolt (20), one end of the pressure spring is abutted against the inner bottom surface of the shaft sleeve (19), and the other end of the pressure spring is abutted against a step between the middle part and the large end of the bolt (20); the bolt (20) is provided with a screw (22) which is used for guiding the bolt (20) to slide along the axial direction of the shaft sleeve (19) and limiting the axial movement of the bolt (20) along the shaft sleeve (19);
when in use, the handle (18) is pulled outwards along the axial direction of the shaft sleeve (19) to enable the handle (18) to drive the bolt (20) to retract into the shaft sleeve (19) and rotate for a set angle, after the bolt (20) is locked by a screw (22) to adjust the angle between the left connecting rod (9) and the left forked connecting rod (11) and the angle between the right connecting rod (10) and the right forked connecting rod (12) to set values, reversely rotates and loosens the locking function of the screw (22) to enable the bolt (20) to rebound under the action of the pressure spring (21), and the handle (18) is pulled to the shaft shoulder of the shaft sleeve (19), the bolt (20) in the bolt component II (25) respectively locks the left connecting rod (9), the left fork-shaped connecting rod (11) and the right connecting rod (10) and the right fork-shaped connecting rod (12), and the bolt (20) in the bolt component III (26) respectively penetrates through the horizontal guide groove (2) to respectively lock the left fork-shaped connecting rod (11) and the right fork-shaped connecting rod (12) with the horizontal guide groove (2).
