a hat having two connection portions, each connection portion of the two connection portions formed to two opposite sides of the hat, respectively;

a protective shield;

two connectors each having a first end part and a second end part respectively formed to two ends of the connector, the two respective first end parts of the two connectors respectively connected to the two connection portions of the hat, the second end part of each of the two connectors including a first ball and a first stop which is located below the first ball;

two first arms each having a first section and a second section which is angularly formed to the first section, the two respective first sections respectively and pivotably connected to the two respective second end parts of the two connectors, the two respective second sections respectively and pivotably connected to the protective shield, each first arm of the two first arms including a protrusion extending therefrom which faces the hat, when the protective shield is pivoted downward and positioned to an operation position, the protrusion of each first arm of the two first arms is located between the first ball and the first stop of the second end part, and

two second arms each having a third section and a fourth section which is angularly formed to the third section, the two respective third sections respectively and pivotably connected to the two respective second end parts of the two connectors, the two respective fourth sections respectively and pivotably connected to the protective shield.

2. The headwear as claimed in claim 1 , wherein each connector of the two connectors includes a first recess which communicates with a first opening formed to a surface of the second end part of the connector, a first resilient member is located in the first recess of each connector of the two connectors and biased between an inner end of the first recess and the first ball which partially protrudes beyond the first opening.

3. The headwear as claimed in claim 2 , wherein the second end part of each connector of the two connectors includes a second ball and a second stop, each first arm of the two first arms includes the protrusion extending therefrom which faces the hat, when the protective shield is pivoted upward and positioned to a folded position, the protrusion of each first arm of the two first arms is located between the second ball and the second stop.

4. The headwear as claimed in claim 3 , wherein each connector of the two connectors includes a second recess which communicates with a second opening formed to a surface of the second end part of the connector, a second resilient member is located in the second recess of each connector of the two connectors and biased between an inner end of the second recess and the second ball which partially protrudes beyond the second opening.
