Embodiment

Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below With reference to embodiment, the utility model is expanded on further.

Figure is referred to, the utility model provides a kind of technical scheme：One kind impact electric hammer, including hammer body 1 and assist handle 2.Motor, drill bit rotating mechanism, beater mechanism in electric hammer are all located in hammer body 1, and drill bit can insert in the front end of hammer body 1, auxiliary Handle 2 is located at the middle part of hammer body 1 and is located at the rear end of hammer body 1 close to bit location, operation handle 3.So that right standard rudder operates as an example, electric hammer is used When, the right hand holds operation handle 3 and presses button above, and left hand holds assist handle 2 to keep electric hammer stable.

In order to change the angle of assist handle 2, assist handle 2 includes body and shank 21, and body is placed on outside hammer body 1 And be rotatably assorted with hammer body 1, shank 21 and body grafting, assist handle 2 are rotated by body hammer body 1, so as to according to not With circumferential position of the Operating condition adjustment assist handle 2 on hammer body 1, the arm and hand for making operating personnel are in pleasant shape State.

As shown in Fig. 2 body includes first set 22 and second set 23, first set 22 is placed on outside hammer body 1, second set 23 and A set of 22 is axially vertical, and second set 23 of end is fixedly connected on the excircle of first set 22, and shank 21 inserts second set 23 In vivo.

Also include being used to connector 4 fixed between shank 21 and second set 23, connector 4 including latch 41 and spring 42, the through hole corresponding with latch 41 is provided with second set 23, and the blind hole corresponding with latch 41, latch 41 are provided with shank 21 One end slidably through the through hole on second set 23 and is inserted in the blind hole of shank 21, and the middle part of latch 41 has flange 411, bullet Spring 42 is placed on outside latch 41, and the both ends of spring 42 are connected with flange 411 and second set 23 respectively.One end of latch 41 and shank 21 are blind The cross section in hole is square, after latch 41 is inserted in the blind hole of shank 21, passes through latch between shank 21 and second set 23 41 are fixedly connected, and when holding the rotation of shank 21, connect between shank 21 and second set 23 i.e. body and more consolidate, meanwhile, when When needing to change shank 21, latch 41 is extracted from shank 21, easy to operate.

Support 25 is connected be coaxially cased with circumferentially surrounding connector 4 outside second set 23 the 3rd set 24, second set 23, 3rd set 24 can be rotatable around its axis be arranged on support 25, there is arc block 26, arc block on the 3rd set 24 of inner periphery 26 are protruded by circumferential 3rd set 24 axis direction of the 3rd set 24 of inner circle, and the other end of latch 41 is connected with roller 43；When When turning to arc block 26 for three set 24 and being contacted with roller 43, latch 41 can be inserted into the blind hole of shank 21, when the 3rd set of 24 rotation When being contacted to its inner periphery with roller 43, latch 41 exits the blind hole of shank 21.Latch can be driven by rotating the 3rd set 24 41 disengaging shanks 21, as shown in figure 3, when the top contact of roller 43 and arc block 26, latch 41 is inserted in blind hole, latch 41 Second set 23 and shank 21 are connected；The 3rd set of position shown in 24 to Fig. 4 is rotated, arc block 26 does not contact with roller 43, Under the effect of spring 42, latch 41 moves to the 3rd set of 24 inner peripherys, and the blind hole of shank 21 is left in the end of latch 41, shank 21 and the Between two set 23 only circumferentially between gap coordinate, shank 21 more can disassemble easily from second set 23.

As shown in figure 5, the top of arc block 26 has an arcwall face 261 of indent, arcwall face can with the circular contact of roller 43, Certain frictional resistance is applied by the arcwall face pair roller 43 of indent, it is necessary to which applying certain torque to the 3rd set 24 can just make 3rd set of 24 rotation, so as to prevent that the 3rd set 24 circumferentially channels bit, that is to say, that the position that latch 41 can be made to insert after shank 21 It is more stable.

In order that shank 21 with second set 23 it is circumferential be connected more stable, connector 4 and corresponding arc block 26 is along the Two set 23 circumferential uniform multiple.

The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above, for For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the utility model is by institute Attached claim rather than described above limit, it is intended that will fall in the implication and scope of the equivalency of claim All changes are included in the utility model.Any reference in claim should not be considered as to the involved right of limitation It is required that.
