A force-limiting and damping device has a body, a tapping element, and an elastic element. The body has a connecting segment and a holding segment. The connecting segment is formed on an end of the body and has a mounting hole. The holding segment is formed on the body opposite the connecting segment. The tapping element is connected to the body to move relative to the connecting segment. The elastic element is mounted between the tapping element and the connecting segment to abut against the tapping element and to enable the tapping element to move relative to the connecting segment. The structural relationship between the connecting segment, the tapping element, and the elastic element may provide a delayed rebound and damping effect to the reaction force, and the applied force is continuously transferred to a tapping object, and this may reduce noise and the loss of energy.

A hammer assembly for a power tool. The hammer assembly provides a first, proximal engagement portion couplable directly to a backside of the power. A second, distal engagement portion is directly connected to the first engagement portion. A head portion is directly connected to the second engagement portion. The second engagement portion provides one or more chambers, each chamber housing a spring for storing energy imparted by compressive forces against the head portion. Each spring directly interconnecting the first and second engagement portions through an open side of the chamber facing the first engagement portion. There is a gap between the first and second engagement portions, between their respective distal and proximal surface, which is spanned by the spring, enabling the latter to deflect before said surfaces contact under compressive loading.

A slide and pull hammer device includes three major components, namely, a guide sleeve, a drive bar and an impact head. The drive bar is inserted within the guide sleeve. The impact head is secured within the distal end of the guide sleeve, and has a portion which protrudes beyond the guide sleeve distal end. The drive bar is operable to impact both a distal end and a proximal end of the guide sleeve to apply force to objects in at least two opposite force directions. One force applied by the device includes a hammering or compression force, and another force applied by the device includes a tension or withdrawing force.

A hammer having a handle and head, the head comprising a cavity encapsulating a slug. The slug is configured to move in at least one direction within the cavity upon impact of the hammer with a target, reducing the transfer of momentum into the handle of the hammer and thus reducing vibration of the hammer in a user's hand. This dampening of the vibration can improve user ergonomics by minimizing fatigue caused by vibrations during continued use of the hammer.
