[0030] Referring to Figure 1 The stop piece 3 has second matching portion 31 and second connecting portion 32, and the stop piece 3 is rotatably connected to the pedestal 1, and the second matching portion 31 is used to abut against the first matching portion 22 in locking state and separate from the first matching portion 22 in unlocking state, wherein the first connecting portion 23 and the second connecting portion 32 can be respectively formed by sheet metal bending to form a protrusion perpendicular to the plane of the pedestal 1.

[0031] The first connecting portion 23 and the second connecting portion 32 are connected by the elastic member 4, and are used to elastically connect the first connecting portion 23 and the second connecting portion 32 to maintain the locking state or the unlocking state.In operation, one end of the elastic member 4 is fixedly connected to the first connecting portion 23, and the other end is connected to the second connecting portion 32, and the elastic force of the spring keeps the first matching portion 22 and the second matching portion 31 in close abutment in locking state, and when the locking state is switched to the unlocking state, the first matching portion 22 and the second matching portion 31 are misaligned, and the second connecting portion 32 of the lock tongue 2 always remains open under the continuous pulling force of the elastic force, so that the switching between complete locking and unlocking of the two matching mechanisms can be completed by a single spring without motion interference, and the two ends of the elastic member 4 always provide elastic pulling force regardless of the unlocking or locking state, so that the lock tongue 2 and the stop piece 3 can maintain good matching relationship, and good smooth transition can be maintained in switching state to provide better matching relationship.

[0032] Preferably, the first matching part 22 is a side surface formed on the lock tongue 2, the stopper 3 is further formed with a guide surface 33 adjacent to the first matching part 22, the included angle between the guide surface 33 and the first matching part 22 is obtuse, the second matching part 31 is a side surface formed on the stopper 3, and the first matching part 22 and the second matching part 31 are matched in surface-to-surface. The first matching part 22 and the second matching part 31 are two planes or curved surfaces that can be matched in surface-to-surface, which are not limited herein. When the state is switched, part of the side surface of the stopper 3 slides against the guide surface 33 and gradually rotates along the guide surface 33, which can ensure stability during state switching and avoid excessive gap when the lock tongue 2 is flipped, resulting in excessive vibration of each component connected to the lock tongue 2 and the lock tongue 2 itself, and long time to avoid elastic failure and decrease in coordination of mechanical cooperation.

[0033] Preferably, the lock tongue 2 is formed with a guide angle 24 adjacent to the first matching part 22, one side of the guide angle 24 is connected to the second matching part 31, and in the unlocking process, the external force connected by the second connecting part 32 drives the stopper 3 to rotate, so that the guide angle 24 slides against and then separates from the guide surface 33, and drives the lock tongue 2 to open the gap 11. The guide angle 24 can be an obtuse chamfer, which is not limited herein. When the state is switched, the guide angle 24 slides along the guide surface 33 after bypassing the second matching part 31, so that the spring can quickly contract, and the change speed of the spring gradually increases as it approaches the unlocking state, which can provide stable elasticity and avoid spring failure caused by long-term cyclic use.

[0035] Preferably, the elastic member 4 is a spring, and the angle between the elastic force direction of the spring and the first fitting part 22 is 40-60 degrees in the locked and unlocked states. During movement, the elastic force direction of the spring also rotates, avoiding single-direction elastic force, so that the first fitting part 22 and the second fitting part 31 cannot keep good adhesion in each state under action decomposition, resulting in poor mechanical fitting degree and finally reducing reliability.
