[0024] As Figure 1As shown, the inner side wall of the plug body 1 is provided with a limiting slope 10, which is located at the inner end of the square hole. When the pressing rod 9 is not under force, the limiting slope 10 is in contact with the connecting arm to limit the limit position of the connecting arm moving outward during the forward movement of the stop rod. The cavity of the plug body 1 is provided with a limiting block 15, which is arranged on both sides of the top rod 11. The limiting block 15 is located between the first stop rod 6 and the second stop rod 7, limiting the relative distance between the first stop rod 6 and the second stop rod 7.

[0025] Working principle: for this kind of press-out safety plug, when the plug is inserted into the socket, the top rod 11 on the lower surface of the plug body 1 is subjected to an upward force to compress the main spring 12. The head of the top rod 11 is provided with a conical boss, which enters the conical cavity composed of the first stop rod 6 and the second stop rod 7. By compressing the first stop rod 6 and the second stop rod 7, the auxiliary spring 8 is compressed and moves outward. The top rod 11 continues to move upward. When the plug body 1 is completely inserted into the socket, the top rod 11 stops moving upward. At this time, the lower surface of the conical boss of the top rod 11 is slightly higher than the upper surface of the first stop rod 6 and the second stop rod 7. Under the action of the auxiliary spring 8, the first stop rod 6 and the second stop rod 7 move to the center.

The first stop rod 6 and the second stop rod 7 move outward to compress the auxiliary spring 8. When the contact surfaces of the first stop rod 6 and the second stop rod 7 are completely separated, the unlocking is completed. The top rod 11 moves downward under the action of the main spring 12 until the lower surface of the boss of the top rod 14 is in contact with the limiting spring 13 to stop moving. The plug is ejected, and the work is completed. The pressing rod 9 on one side can also be pressed, and the effect is the same.

[0027] The main spring 12, the auxiliary spring 8 and the limiting spring 13 of the press-type ejection mechanism are placed in the cylindrical grooves which are in conformity with the shapes of the springs, so that the springs can only be stretched and compressed. The limiting block 15 is arranged in the cavity of the plug body 1, the ejector rod 11 is ejected, the auxiliary spring 8 changes from the compressed state to the elongated state, the stopper rod is pushed to move forward, the limiting block 15 is used to limit the limit position of the forward movement of the stopper rod, and the arc surface of the stopper rod is prevented from touching the elongated main spring 12. The limiting slope 10 is arranged on the inner side wall of the plug body 1, and the pressing rod 9 stops moving outward when the connecting arm touches the limiting slope 10. The spring force auxiliary mode of the application is helpful for the plug to be quickly pulled out, and is safe and reliable.
