Description of drawings

Come the specific embodiment described in the utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is the cutaway view of the handle that discloses of the utility model;

Fig. 3 is the explosive view of handle.

The specific embodiment

As shown in Figure 1, the electric tool that at least one handle is housed is made up of a power tool body 10 and at least one handle 1, and handle 1 is by being threaded onto on the power tool body 10.In diagram, power tool body 10 shows as a sanding machine, in other embodiments, can also be electric drill, electric hammer, saw etc.

As shown in Figure 2, handle 1 comprises a mounting portion 2, a flexible member 3 and a grip portions 4.Mounting portion 2 comprises a bolt 5, and bolt 5 is fixedlyed connected with mounting portion 2, and the threaded portion of bolt 5 stretches out mounting portion 2.Handle 1 is fixedlyed connected with power tool body 10 by the threaded portion of bolt 5.Grip portions 4 has an endoporus 40, and endoporus 40 comprises first and the second portion with second inner diameter d 2, wherein a d1＜d2 with first inner diameter d 1.Flexible member 3 comprises a flange section 31 and a bar part 32, wherein, flange section 31 connects between mounting portion 2 and grip portions 4, and bar part 32 is arranged in the endoporus 40 of grip portions 4, and flexible member 3 is connected with grip portions 4 relative fixed with mounting portion 2.

As shown in Figure 3, mounting portion 2 is made up of a ring flange 21 and a bar 22, and bar 22 has a pair of first key 6 and second key, 8, the first and second keys 6,8 to outer process to distribute with respect to the radial symmetric of bar 22 at an end that deviates from ring flange 21.Grip portions 4 has a pair of first groove 7 and second groove 9 on the inner hole wall of its first, thereby allows first key 6 and second key 8 on the bar 22 therefrom to pass in the second portion of endoporus 40 respectively when bar 22 being inserted the endoporus 40 of grip portions 4.In manufacture process, at first first and second keys 6,8 of mounting portion 2 are aimed at first and second grooves 7,9 in the first of grip portions 4, first and second keys 6,8 are moved along first and second grooves, 7,9 other ends to grip portions 4, until first and second keys 6,8 pass first and second grooves 7,9 and and be arranged in the second portion of endoporus 40, in this state, the bar 22 of mounting portion 2 can freely rotate in the endoporus 40 of grip portions 4, and is not shown.At this moment, mounting portion 2 revolved with respect to grip portions 4 turn 90 degrees, make first and second keys 6,8 and first and second grooves, 7,9 positions stagger, first-selection stagger 90 the degree, again mounting portion 2 and grip portions 4 are put into mould together and carry out injection moulding, thereby between mounting portion 2 and grip portions 4, form the flange section 31 of flexible member 3, and the bar part 32 that in the endoporus 40 of grip portions 4, forms flexible member 3.As shown in Figure 2, after injection moulding is finished, stagger in first and second keys 6,8 and first and second grooves, 7,9 positions, and first and second keys 6,8 are positioned at the below of first inner diameter d 1, therefore in the use of handle 1, even flexible member 3 is tired impaired and when losing adhesion, can not come off owing to less the articulating of first of internal diameter of the endoporus 40 of first and second keys 6,8 on the bar 22 and grip portions 4 between grip portions 4 and the mounting portion 2, make handle 1 more safe and reliable.

The electric tool that at least one handle is housed that the utility model disclosed is not limited to frame mode mentioned above and shown in the drawings, for example the quantity of the key on the mounting portion is not limited to two, can be more than one or two, key also can be projection or other shapes in addition, as ratchet etc., on basis of the present utility model, concrete shape of other members and position have been made conspicuous change, substituted or revised, all within the utility model scope.
