Electric starter with manual turning function

An electric starter with a manual turning function, comprising:

• a main shaft (1), a drive gear mechanism (2), a shift fork (3), an electromagnetic relay guide rod (4) and a first return spring (5) are arranged in a housing of the electric starter,
• wherein an upper fork of the shift fork (3) bites the electromagnetic relay guide rod (4);
• a lower fork of the shift fork (3) bites the main shaft (1);
• and a middle portion of the shift fork (3) is hinged to the housing of the electric starter via a hinge joint (A),
• wherein the electric starter further comprises a gear shifting mechanism and a turning mechanism,
• wherein the gear shifting mechanism comprises a force receiving component which extends out of the housing of the electric starter and serves as an external force applying point so as to promote the electromagnetic relay guide rod (4) to move towards the turning mechanism, a normally closed switch (7) for cutting off a power supply of the electric starter when the force receiving component moves to an extreme position, a positioning component for locking the force receiving component when the force receiving component moves to the extreme position, and a first return component which enables the force receiving component to automatically return to an original state when the force receiving component is unlocked, and
• wherein the turning mechanism is arranged on a first side of the main shaft (1) furthest from the shift fork;
• an opening (8) for insertion of a wrench or a sleeve-like turning tool is provided in a housing of the turning mechanism;
• and the main shaft (1) is indirectly driven to rotate by the turning mechanism via a transmission mechanism or directly driven to rotate by the turning mechanism via a turning tool.
