[0002] At present, the hammer or iron hammer used to strike the nail body in the wood, cement wall or metal plate in the industry will often bounce due to the reaction force when striking, which will not only shorten the striking surface of the hammer or iron hammer The time of contact with the nail body will easily cause the nail body to bend or deflect, and the reaction force of its immediate rebound will be converted into heat energy and noise loss, which will relatively reduce the effectiveness of the user's force. That is to say, the exerted force cannot be fully used on the nail body, so that the user needs to strike the nail body several times before the nail body can be knocked into and fixed in the board or wall, which increases relatively. The number of times of knocking and the time required; in addition, when the user holds the handle of a hammer or iron hammer, the bounce vibration generated during the knocking will also make the user feel uncomfortable; moreover, the current existing medical treatment With a hammer or surgical hammer, the percussion surface is mostly a rigid structure. Therefore, when the dentist uses...

[0074] Please cooperate with you like Figure 18 The twelfth preferred embodiment of the restricted shock absorbing device shown in the present invention has image 3 The difference in the first preferred embodiment is that the bonding portion 11K is laterally throughout the slot 112K, the sleeve portion 21k extends into the slot 112k via the bottom of the joint portion 11k, and the locking portion 23K The slot 112k is coupled to the sleeve portion 21k, and the force console 34K is disposed between the bonding portion 11k and between the locking portions 23k and within which the slot 112k is located. When the tap force is too large, the locking portion 23k will collide with the top of the slot 112K, remind the user to tap the upper limit of the power, and can provide unleadolerable tap effects.
[0075] Further, the shock absorbers 33, 33b, 33c, 33d, 33e, 33f, 33g, 33d, 33i, 33f, 34a, 34g, 34i, 34k, can be used as a spring, rubber, Silica gel, metal gasket, a resilient metal block or a resilient material having a fixed shape or the like, or the spring can be formed in the rubber or silicone, or both can be the aforementioned various One of the elastic materials is used, and the present invention does not limit its matching mode.
[0076] As described above, it is merely the preferred embodiment of the present invention, which can be used in the design of the hammer, ax, golf club head, and the limit of the limit of the strike tool, and it is not a restriction in any form of the present invention. Any equivalent embodiment of the present invention will not be departed from the technical solution of the present invention, using the technical solutions of the present invention, and They are still within the scope of the technical solutions of the present invention.
