Problems solved by technology

Therefore, when the desired anti-vibration effect is obtained by making the deformation direction of the elastic body close to the long axis direction of the drill bit, the arrangement interval between the rotating shaft and the elastic body will increase, and as a result, the anti-vibration handle will be too large in the vertical direction.
Therefore, the vibration-type anti-vibration handle is difficult to apply to relatively small work tools, and there is still room for improvement in this regard.

Embodiment Construction

[0030] Below, refer to Figure 1 to Figure 6 Embodiments of the present invention will be described in detail. In the embodiment of the present invention, a cordless hammer drill will be described as an example of a hand-held power tool. figure 1 It is an external view showing the overall configuration of the hammer drill 101 according to this embodiment. figure 2 It is a side view showing the internal structure of the hammer drill 101 by dotted lines and a partial section. Such as figure 1As shown, the main body of the hammer drill 101 generally has: a body part 103 forming the outer contour of the hammer drill 101, a drill bit 119 detachably mounted on the front end region of the body part 103 by means of a drill sleeve 137, and a drill bit 119 connected to the body part 103. The handle 109 that can be held by the user on the opposite side of the drill bit 119 and the storage power source 107 installed on the lower side of the main body 103 . The main body 103 correspon...

Abstract

A hand-held power tool comprises a power tool body having a tip end region to which the tool bit is coupled, and a handle provided on the rear of the power tool body opposite to the tool bit, the handle being held by a user of the power tool, wherein the handle is connected to the power tool body via an elastic element and can slide with respect to the power tool body in an axial direction of thetool bit and an extending region provided with the power tool body, the extending region extending to a lower region of the handle to receive the sliding movement of the handle.

Description

technical field [0001] The present invention relates to an anti-vibration handle of a hand-held work tool, such as a hammer or a hammer drill, which drives a tip tool in a certain cycle. Background technique [0002] Japanese Unexamined Patent Publication No. 2005-219195 discloses a configuration of a hand-held electric hammer provided with a vibration-proof handle. In this electric hammer, there is disclosed a configuration in which a vibration-proof handle held by an operator during jarring work is attached to the hammer main body via a vibration-absorbing elastic body. Specifically, the anti-vibration handle, relative to the rear part of the hammer body, has one end (lower end) in the direction of the long axis of the hand grip and uses the rotation axis as a fulcrum to rotate relatively along the long axis of the drill (front and rear direction). The (upper end) side is connected via an elastic body. [0003] In the above-mentioned rotary anti-vibration handle which is...
