The invention discloses a solenoid actuator, wherein a limiting pin (601) comprises a sliding portion (64), a neck portion (651) and a taper portion (661) which are arranged in order from a rear end to a far end of the limiting pin (601), and meets relational expressions of D1>D2, D3>D2, and D1>=D3, wherein D1 is the external diameter of the sliding portion (64), D2 is the minimum outer diameter of the neck portion (651), and D3 is the maximum diameter of the neck portion (661). When the limiting pin (601) leaves a jointing groove (14) and moves backwards, the neck portion (651) is accommodated in a supporting portion (722). |
