Cleverly changing the commutation structure of the electric push rod

The electric push rod is a combined component that is widely used by mechanical designers due to its smooth transmission speed and flexible installation. However, this component often fails during use and burns the motor in severe cases. 1. Fault analysis can be seen from the commutation structure of the electric push rod (Fig. 1). The reversing limit rod 3 is a round stick. This round stick is extended to the extreme back tension by the push rod, and is used for reciprocating motion. Touch the limit switch 4 or 2. The contact position of the limit rod 3 with the limit switch 4 or 2 is a cylinder and a ball head, and is required
