Embodiment 1

[0024] The hand-held impact wrench of this embodiment is as figure 1 , figure 2 and image 3 As shown, it includes a housing (not shown in the figure) in which the drive motor is placed, and the lower part of the housing extends out the handle 1 formed by the paired two handle housings 1-A, 1-B. The bottom of the handle 1 has two conjoined connection shells 3-A, 3-B for inserting the battery pack 2 . Connecting seat 4 is housed in the two handle shells 1-A, 1-B that fit together. A circuit board 5 is housed in the two connecting shells 3-A, 4-B that are combined.

[0025] Connection seat 4 such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, it is composed of an upper base body and a lower base body using the rubber encapsulation process. The upper base body is a metal rigid component 4-A with circular through holes on both sides of the lower part, and the lower base body is a rubber elastic component 4-B embedded in two circular through holes. Between the...

Abstract

The invention relates to a handheld electric tool and belongs to the technical field of electric tools. The lower part of a casing of the tool extends to form a handle comprising two handle casings, and two correspondingly combined connecting casings are arranged at the bottom of the handle; a connecting seat formed by combining an upper seat body and a lower seat body is mounted in the two handle casings, one of the upper and lower seat bodies is a rigid component provided with a through hole, the other one of the upper and lower seat bodies is an elastic component embedded in the through hole, and horizontal through holes are formed in the rigid component and the elastic component respectively; a horizontal hinge pin penetrating through the horizontal through hole of one of the rigid component and the elastic component extends from the inside of one of the two correspondingly combined handle casings, and the horizontal hinge pin is fixedly connected with the other one of the two correspondingly combined handle casings after corresponding combination; a horizontal hinge pin penetrating through the horizontal through hole of the other one of the rigid component and the elastic component extends from the inside of one of the two correspondingly combined connecting casings, and the horizontal hinge pin is fixedly connected with the other one of the two correspondingly combined connecting casings after corresponding combination. The handheld electric tool can effectively isolate vibration, and all parts of the electric tool cannot loosen and fall when impacted accidentally, so that safety and reliability are guaranteed.

Description

technical field [0001] The invention relates to an electric tool, in particular to a hand-held electric tool, and belongs to the technical field of electric tools. Background technique [0002] Hand-held electric tools such as electric wrench and electric drill are one of the most commonly used electric tools. Its typical structure includes a housing for arranging the motor for driving the tool head. The bottom of the handle has a battery pack insertion structure. During use, the vibration of this type of electric tool will inevitably be transmitted to the battery pack it is plugged into, which will easily lead to damage to the plugged part and unreliable plugging of the battery pack, especially the electric wrench with impact function, the vibration during use is very strong. [0003] For this reason, Chinese invention patent application number 200810111227.8 (patent family JP4977533B2) discloses an electric tool capable of preventing vibration of a battery pack in the el...
