The support device further comprises a locking assembly 2 and a lock catch 111. The locking assembly includes a locking rod 21, a pin 22, a mounting seat 25 and an elastic body 24. The top of the locking rod is provided with a hook part 212, the bottom of the locking rod is rotationally connected with the mounting seat through a pin shaft 22, and the pin shaft is parallel to the second joint rotating shaft, so that the locking rod can rotate in a pitching mode within a certain range relative to the mounting seat. The elastic body is tightly pressed between the bottom of the lock rod and the mounting seat, namely the elastic body is always in a pressing state, so that the elastic body can provide a restoring force for the lock rod, and the direction of the restoring force can be perpendicular to the pin shaft. The mounting seat is fixed with the lower support assembly. The latch 111 is provided on the side of the upper support arm assembly facing the lower support arm assembly.
The lock catch has two relatively static balance states, namely a locking state and an unlocking state, and in the locking state, the lock rod is vertically placed, and at the moment, the hook part of the lock rod can buckle the lock catch; in the unlocked state, the locking bar lies flat.
In this embodiment, the upper support arm assembly has a lower surface 110 facing the lower support arm assembly, the lower support arm assembly has an upper surface 130 facing the upper support arm assembly, the latch may protrude downwardly from the lower surface, and the lock lever may protrude upwardly from the upper surface.
In the present embodiment, the lock lever can be stabilized in the locked state and the unlocked state under the action of the weight of the lock lever, the restoring force of the elastic body, and the supporting reaction force of the mount or the lower support arm assembly to the lock lever.
As shown in fig. 1 to 19, a support device 10 comprises an upper support arm assembly 11, a coupling joint 12 and a lower support arm assembly 13; the upper support arm assembly 11 is connected with the lower support arm assembly 13 through a coupling joint 12, so that the upper support arm assembly 11 can rotate left and right in a horizontal plane and rotate up and down in a vertical plane relative to the lower support arm assembly 13. The range of left-right rotation can be designed according to requirements, such as +/-90 degrees. The range of up and down rotation can be designed according to requirements, such as +30 degrees to-15 degrees.

The locking assembly 2 comprises a locking rod 21, a pin 22, a guide pressing sleeve 23, a compression spring 24, a mounting seat 25 and a split collar 26. The compression spring 24 is pressed into the guide hole 31 of the mounting seat 25 through the guide pressing sleeve 23; the locking rod pin hole 29 is coaxial with the mounting seat pin hole 29, and the pin shaft 22 is inserted into the locking rod pin hole 29 and the mounting seat pin hole 29 simultaneously; the split washer 26 is then used to axially position the pin 22 to ensure that the pin 22 will not come loose from the mounting seat pin hole 29 under the action of the split washer 26. Finally, the locking assembly 2 is fixed inside the lower support arm assembly 13 in a screw connection mode, and the lock rod 21 can rotate around the pin shaft 22 within a certain range.

At this time, after the lock rod 21 is buckled into the lock catch 111, a mechanical dead point exists on the structure, and the lock rod 21 cannot be buckled from the lock catch 111 without the action of external tripping force.
The locking action of the locking assembly is as follows:
1. automatic locking process of left and right side snap-in:
referring to fig. 8 and 9, the lock lever 21 is in a locked state, first, the upper support arm assembly 11 is pressed down, then the upper support arm assembly 11 is close to the lock lever 21 from the left side or the right side, and then, the lock lever 21 is acted by external force through the cooperation of the second guide surfaces 112 on the left side and the right side of the lock catch and the first guide surfaces 211 on the left side and the right side of the hook part of the lock lever, and the lock lever 21 rotates around the pin 22 by a certain included angle (smaller than the limit included angle θ capable of changing the state) and simultaneously, at theRUnder the action, the hook part 212 of the lock rod is slowly buckled into the first buckle groove 113 of the lock buckle, and the automatic locking function is realized.

3. When external force acts on the lock rod 21 and the moment arm is not zero;
with reference to fig. 16 and 17, the lock lever 21 has a balance couple ML ═ M, the lock lever 21 swings back and forth around the pin 22, and when the lock lever rotates through the limit included angle θ, the lock lever is converted from the locked state to the unlocked state, which is a reciprocal process. This process requires that two conditions exist simultaneously, under the action of an external force, and the limit angle θ is rotated.

When the lock rod is in a locking state, the guide pressing cylinder can abut against the bottom surface of the protrusion, as shown in fig. 3; when the lock rod is in the unlocking state, the guide pressing cylinder can be pressed against the side surface of the protrusion, as shown in fig. 18. The arm of the restoring force of the compression spring 24 may be 0 in the locked state. In the unlocked state, the arm of the restoring force of the compression spring may be different from 0.
In this embodiment, the hook portion on the top of the lock lever 21 has a second catching groove 213, and when locking, the lock catch is caught in the second catching groove of the hook portion, and the hook portion is caught in the first catching groove 113 of the lock catch. The upper support arm assembly has a lower surface 110 facing the lower support arm assembly and the lower support arm assembly has an upper surface 130 facing the upper support arm assembly.
