Electric jack with current limiting protector

An electric jack with a current limiting protector, comprising a current limiting protector (1), a four-pin double-reset switch (2), a control motor (3), and a supporting leg main body (4), wherein

• the current limiting protector (1) is connected in parallel to the control motor (3) through the four-pin double-reset switch (2);
• the current limiting protector (1), the four-pin double-reset switch (2), and the control motor (3) are detachably mounted on the supporting leg main body (4);
• a first wiring terminal (101), a second wiring terminal (102), a third wiring terminal (103), a fourth wiring terminal (104), a fifth wiring terminal (105), and a current limiting protection circuit (106) are distributed on the current limiting protector (1);
• the first wiring terminal (101) is connected to a negative electrode of the four-pin double-reset switch (2);
• the second wiring terminal (102) is grounded;
• the third wiring terminal (103) is connected to an input end of a power supply in parallel with a positive electrode of the four-pin double-reset switch (2);
• the fourth wiring terminal (104) and the fifth wiring terminal (105) are respectively connected to the control motor (3);
• and
• the current limiting protection circuit (106) is configured to perform overload power-off protection on the control motor (3).
