The present invention relates to a replaceable hitting structure for a hammer which is capable of prolonging service life of the hammer
Referring to
However, as hitting object by using the hitting block, the hitting block removes from the body easily because of impact force and vibration, thus damaging the screwing post often.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a replaceable hitting structure for a hammer which is capable of prolonging service life of the hammer.
To obtain the above objective, a replaceable hitting structure for a hammer provided by the present invention contains: a body, a handle extending downwardly from a middle portion of the body, and at least one hitting block connected with the body.
The body includes an accommodation extension arranged on one end thereof, a housing groove defined in the accommodation extension, and a peripheral trench defined in the housing groove.
Each hitting block includes a hammering face formed on a first side thereof, a connecting face arranged on a second side thereof, a coupling post extending outwardly from the connecting face and accommodated in the housing groove, a fixing notch defined on an outer wall of the coupling post, and a positioning ring retained in the fixing notch.
When the coupling post is housed in the housing groove, the positioning ring contacts with the peripheral trench of the body, and the connecting face engages with the accommodation portion matingly.
With reference to
The body 1 includes an accommodation extension 11 arranged on one end thereof, a housing groove 12 defined in the accommodation extension 11, and a peripheral trench 13 defined in the housing groove 12. Each hitting block 3 includes a hammering face 31 formed on a first side thereof, a connecting face 32 arranged on a second side thereof, a coupling post 33 extending outwardly from the connecting face 32 and accommodated in the housing groove 12, a fixing notch 34 defined on an outer wall of the coupling post 33, and a positioning ring 35 retained in the fixing notch 34. When the coupling post 33 is housed in the housing groove 12, the positioning ring 35 contacts with the peripheral trench 13 of the body 1, and the connecting face 32 engages with the accommodation portion 11 matingly, hence said each hitting block 3 is connected with the body 1 quickly and securely.
When the positioning ring 35 contacts with the peripheral trench 13, the connecting face 32 engages with the accommodation portion 11 matingly so that said hitting block 3 absorbs impact force and vibration of the body 1 as hitting an object by using the hammer
The positioning ring 35 is flexible and is made of rubber (such as a C ring).
Thereby, the hitting structure of the present invention is capable of replacing hitting blocks 3 of various sizes based on using requirements, as shown in
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
