The pivot joint angular displacement flexible limiting body is to be arranged between each pivot seat 103g and 801g and between 802g and 104g with elastic or flexible material 204, such as PU or other plastics or elastic bodies made of rubber; in order to support the two It is in a flexible steady state when it is not stressed, and it can make a flexible angular displacement along the hammering direction when it is stressed.

As shown in Fig. 25 and Fig. 26, the present invention includes a hammer head structure 100h, a handle structure 200h, a pivot 105 and a flexible restricting body for the angular displacement of the pivot joint.

The hammer head structure 100h is a swinging hammer head structure, which is an integrated structure according to the required geometric shape by selecting materials.

The handle structure 200h is a pivoted handle structure, which is a combined structure composed of selected materials according to the required geometric shape, and includes handles 201h and pivot blocks 700h made of different materials.

The two ends of the pivot block 700h are respectively a joint hole 702h for assembling the handle 201h and a pivot seat 701h coupled to a single pivot ear in the pivot seat 704h slot of the hammer head structure 100h. The grips 201h of different materials assembled in the joint hole 702h of the pivot block 700h are firmly combined with the joint hole 702h by tight fit, embedded fixed piece tight, glued or thermal expansion and contraction, or other conventional methods.

The pivot 105 can be sleeved or not sleeved with an elastic or flexible material body 204 as required, and pivotally installed on the hammer head structure 100h and the pivot block 700h pivot seat 701h by locking, riveting or fitting , to form a swingable pivot joint that swings along the hammering direction, so that when the hammerhead structure 100h is under hammering force, there is a gap between the hammerhead structure 100h and the handle structure 200h pivot seat 704h, 701h that can be hammered along. direction for angular displacement swing.

The flexible restricting body for the angular displacement of the pivot joint is at least one elastic structure 703h extending from the handle structure 200h pivot seat 104h to the hammering direction; Set a tool elastic or flexible material 204, such as PU or other plastics or elastic bodies made of rubber; in order to support the two, they are in a flexible and stable state when they are not stressed, and they can be flexed along the hammering direction when they are stressed. sexual angular displacement.

In practical applications, the shape and material of the hammer head structure 100j can be selected according to needs, and among them, the claw hammer with single-end nail-pulling function can be traditionally installed on the hammer head; it can also be used as shown in Figure 27. As shown, the nail pulling head 300j is disposed above the end of the pivot seat 104j of the handle structure 200j.

In summary, the present invention sets one or more swingable pivot joints that can swing along the hammering direction through the structure of the hammer head and the structure of the handle in the hammering direction, so that the reaction force generated at the moment of hammering can be borrowed. The direction can be swung with the pivot as the center to release the swing direction, so as to avoid damage to human fingers and limbs.
