Double-shockproof spring mechanism, cam ejection mechanism and single-side guide rail ejection bin

A cam ejection mechanism (2) comprising:

• a power device (22);
• an ejection cam (23);
• a pushing plate (24);
• and
• a double-shockproof spring mechanism (21);
• wherein the double-shockproof spring mechanism (21) further comprises a guide rod (211), a first elastic element (212), a slider (213) and a second elastic element (214);
• wherein the power device (22) is in transmission connection with the ejection cam (23), the ejection cam (23) is capable of being abutted against the slider (213) and pushing the slider (213) to slide along the guide rod (211) so as to deform the first elastic element (212), and the slider (213) is detachable from the ejection cam (23) so that the first elastic element (212) drives the slider (213) to slide reversely along the guide rod (211);
• wherein the pushing plate (24) is connected with the slider (213) and slides synchronously with the slider (213);
• wherein the guide rod (211) is provided at one side of an ejection bin body (1);
• and
• wherein the first elastic element (212), the slider (213) and the second elastic element (214) are all sleeved on the guide rod (211), the slider (213) is provided between the first elastic element (212) and the second elastic element (214), both ends of the slider are respectively abutted against the first elastic element (212) and the second elastic element (214), and the slider (213) is slidable along the guide rod (211) under the action of the first elastic element (212) and the second elastic element (214).
