Specifically, the clamping grooves 211 are located at one end of the limit protruding portion 21 away from the lamp holder 20, the clamping grooves 211 and the end faces of the limit protruding portion 21 are arranged at intervals along the extending direction of the limit protruding portion 21, the notches of the clamping grooves 211 are located on the side faces of the installation protruding portion, and when the limit protruding portion 21 extends into the accommodating cavity 122, the clamping grooves 211 are also located in the accommodating cavity 122. The position motion of locating part 40 relative spacing hole 124, when spacing convex part 21 inserts in spacing hole 124, locating part 40 can move towards spacing convex part 21, and insert in the joint groove 211, and then restrict spacing convex part 21 and move in spacing hole 124, can make lamp stand 20 and connecting seat 12 lock. When the lamp holder 20 is required to be lowered, the limiting part 40 is separated from the clamping groove 211, so that the limiting part can move relative to the limiting hole 124, and the lamp holder 20 can be lowered. That is, when the limit protrusion 21 is inserted into the limit hole 124, the lamp socket 20 can be locked by the limit, and the lamp socket 20 can be automatically locked. Of course, in other embodiments, the clamping groove 211 may be a through hole.

The structure of the limiting member 40 has various structures, for example, in an embodiment, a fixing portion 125 is disposed on a cavity wall of the accommodating cavity 122, the limiting member 40 is movably mounted on the fixing portion 125, a spring 41 is sleeved on the limiting member 40, one end of the spring 41 is connected to the fixing portion 125, and the other end is connected to the limiting member 40, so as to drive the limiting member 40 to move in a direction away from the engaging groove 211. The hole wall of the mounting hole 112 is provided with a guiding convex part (not shown), the guiding convex part has a guiding surface facing the mounting end 121, the guiding surface gradually approaches to the outer circumferential surface of the mounting end 121 along the circumferential direction of the mounting hole 112 from the hole wall of the mounting hole 112, the side wall of the mounting end 121 is provided with a yielding hole, and the limiting member 40 passes through the yielding hole and abuts against the guiding surface.

Specifically, the limiting member 40 is long, the limiting member 40 is slidably connected to the fixing portion 125, and the sliding direction of the limiting member 40 is the same as the length direction thereof. The spring 41 is connected to the limiting member 40 and the fixing portion 125, respectively, and enables the limiting member 40 to move towards a direction away from the limiting hole 124, one end of the limiting member 40 away from the limiting hole 124 extends out of the yielding hole and abuts against the guide surface, and a roller is arranged at an end of the limiting member 40 and abuts against the guide surface. The guiding convex portion is protruded on the wall of the mounting hole 112, and extends in a long shape along the circumferential direction of the mounting hole 112, the guiding surface is a surface of the guiding convex portion facing the outer circumferential surface of the mounting end 121, and the guiding surface has a first end far away from the mounting end 121 and a second end close to the mounting end 121. When the limiting member 40 abuts against the first end, the limiting member 40 is away from the limiting hole 124, and when the limiting member 40 abuts against the second end, the limiting member 40 can move to the limiting hole 124 and be inserted into the clamping groove 211. That is, when the connecting base 12 rotates, the limiting member 40 can move from the first end to the second end, and in the moving process, the limiting member 40 gradually approaches the limiting hole 124, and when the limiting member 40 moves to the second end, the limiting member 40 can be inserted into the engaging groove 211. Since the limiting member 40 is always abutted against the guiding surface under the action of the spring 41, when the connecting seat 12 rotates reversely, the limiting member 40 can move from the second end to the first end and gradually move away from the limiting hole 124. So only need control connecting seat 12 to rotate, can realize the locking and the loosening of lamp stand 20, simple structure can simplify the overall structure and the reduce cost of lamps and lanterns. Of course, in other embodiments, there may be an air cylinder or a motor to drive the limiting member 40.

The fixing portion 125 may be provided with a sliding rail or a sliding groove, so that the limiting member 40 is slidably connected to the sliding rail or the sliding groove, or the fixing portion 125 may be provided with a fixing hole, so that the limiting member 40 is slidably disposed in the fixing hole. In addition, the spring 41 may be disposed outside the limiting member 40, or both ends of the spring 41 may be connected to the limiting member 40 and the cavity wall of the accommodating cavity 122, respectively. In addition, the limiting member 40 may also be plate-shaped, so that the edge of the limiting member 40 extends into the locking groove 211. In other embodiments, a third groove may be provided on the wall of the mounting hole 112, the third groove extends along the circumferential direction of the mounting hole 112, and the groove bottom of the third groove gradually approaches the outer circumferential surface of the mounting end 121 along the circumferential direction of the mounting hole 112, that is, the groove bottom of the mounting groove 111 is a guiding surface. This can reduce the distance between the wall of the mounting hole 112 and the outer peripheral surface of the mounting end 121, and can prevent the stopper 40 from deviating from the guide surface.

When the limiting member 40 extends into the engaging groove 211, since the lifting assembly 30 stops working, the lamp socket 20 may move downward under the action of gravity, and further the limiting member 40 is clamped in the engaging groove 211, so that when the connecting base 12 is rotated from the first end to the second end, the limiting member 40 may be difficult to be pulled out. In order to avoid the above situation, in an embodiment, the side wall of the clamping groove 211 abutting against the limiting member 40 is inclined upward from the groove bottom to the groove opening, and the upper surface of the limiting member 40 is inclined downward gradually in the direction close to the clamping groove 211, so that when the upper surface of the limiting member 40 abuts against the side wall of the clamping groove 211, the acting force of the limiting member 40 in the vertical direction can be reduced, and the acting force of the limiting member 40 in the sliding direction of the limiting member 40 is increased, and when the connecting base 12 rotates, the limiting member 40 can move in the direction away from the clamping groove 211 more easily.
