Abstract
A handle for hand tool has an enclosed hollow cavity for damping with good effect of shock reduction and an insertion slot for connecting hand tool.
Description
The invention belongs to the hand-held tool handle, particularly a kind of hand tool shank with vibration absorption closed cavity.
The hand-held tool of commonly using as iron hammer, must coat the lever lining of the soft material of a sheathed glue in addition at its end usually, provides good grip effect with the frictional force of colloid lever lining, prevents sliding openhanded moving situation and takes place.This lever lining also has cushioning effect slightly, and the reaction force that produces when making operation is slightly slowed down.Yet, because being, the portion that plugs together of hand-held tool and lever lining directly tightly wrap up in cover, the reaction force that acts on the hand-held tool directly is passed to the user on hand through portion of plugging together and lever lining, so its cushioning effect is only by means of the characteristic of glue softwood matter, and its damping effect is relatively poor.
The purpose of this invention is to provide a kind of hand tool shank with vibration absorption closed cavity with the shock-absorbing of sealing cavity, good damping effect.
The present invention has with the hand-held tool portion of plugging together plugs together and plugs together groove, its outer surface and plug together and constitute the sealing cavity between the groove.
Plug together groove because the present invention has with the hand-held tool portion of plugging together plugs together, its outer surface seals cavity with plugging together to constitute between the groove.During use, acting on reaction force on the hand-held tool handles the portion that plugs together and the lever outer surface of instrument and plugs together the sealing lumen indirect transfer that constitutes between the groove to the user, and with its outer surface and plug together the sealing lumen that constitutes between the groove, absorb the vibrations reaction force that bump is produced, good damping effect, thus reach purpose of the present invention.
