Abstract: A damping return hammer includes a grip handle, a first elastic damping arm, a second elastic damping arm, and a hammer head provided at the fronts of the first elastic damping arm and the second elastic damping arm, respectively. The front ends of the first elastic damping arm and the second elastic damping arm are upper and lower respectively, and extend at a certain distance forward and are in the same longitudinal section. The two hammer heads are provided at the front ends of the first elastic damping arm and the second elastic damping arm respectively. A gap is between the two hammer heads and is fitted therein with a rubber energy-storage cushion block.

Abstract: Breathing glasses for purifying air include left and right air filters, an air transmission pipe at the left and right sides thereof, an air curtain ejection and air transmission device and an eye protection cover. The left and the right air filters include a filter casing, a composite filter layer, a built-in air inductor, an intelligent induction chip, a dual-channel variable-frequency turbofan and a miniature motor, a battery and a power control switch, and a lower air transmission transformation connection port. The air curtain ejection and air transmission device ejects air through an upper air curtain outlet groove, a lower air curtain air outlet groove and two breathing air transmission holes to form an air curtain isolation layer to block surrounding unclean air, clean air is ejected from the two breathing air transmission holes. A long-time wearing mode is provided when a portable external air filter is included.
