Abstract

The utility model relates to a forceps type tool with a double-layer structure. The utility model is made of two types of plastics with different hardness. In the utility model, a hard plastics layer is tightly sheathed with a handle; a soft plastics layer is attached to the outer side of the hard plastics; a combination face between the hard plastics and the soft plastics forms a multilayer slope engagement shape. The handle sleeve not only can be firmly sheathed on the handle, but also makes operators feel comfortable when the operators hold the utility model. The utility model has the advantage of practicability.

Description

Double-deck clamp type tool taper knob

The utility model relates to a kind of taper knob of clamp type tool, especially adopts double-decker, and it can overlap and be fixed on the handle, feels comfortably cool when the operator is held.

The taper knob of clamp type tool in the present city, adopt the plastic cement of single character mostly, be enclosed within on the handle to one-shot forming, if plastic cement character is hard, though firmly be enclosed within on the handle, then feel uncomfortable when the operator holds, when plastic cement character is too soft, though when holding, the operator feels comfortable, and should cover landing from the handle easily.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of double-deck taper knob that has is provided, and it can be enclosed within on the handle securely, feels comfortably cool when the operator is held.

The purpose of this utility model is achieved in that and designs a kind of double-deck clamp type tool taper knob that has, adopt same kind but the different again plastic material of hardness, do twice and irritate mold forming, form double-decker, the ebonite layer tightly is placed in handle, the flexible glue layer then is dissolved in the outside of ebonite, so that the operator feels comfortably cool when holding.

Moreover, constitute multilayer slope engagement shape at its hard, soft faying face, this can increase by bonded area, increase fused property, better to reach with bond strength, the effect of difficult drop-off also makes simultaneously for the second time molten material take advantage of a situation easily to slide to and combines, there is not binding site, seamless to reach faying face, more the purpose of cementation.

Owing to adopt such scheme, taper knob is enclosed within on the handle securely, feel comfortably cool in the time of simultaneously the operator being held.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is that taper knob of the present utility model is enclosed within the schematic perspective view on the instrument.

Fig. 2 is the schematic perspective view of taper knob of the present utility model.

Fig. 3 is the perspective exploded view of taper knob of the present utility model.

Fig. 4 is the semi-section schematic diagram of taper knob of the present utility model.

Fig. 5 is the A-A schematic cross-section of Fig. 2.

Fig. 1 is that taper knob of the present utility model (1) is fixed on the handle (21) of instrument (2), and wherein taper knob (1) is to be made of by the combination of joint portion (3) (4) institute two-layer plastic cement.

Shown in Fig. 2,3, be the solid and the decomposing schematic representation of the utility model taper knob, wherein joint portion (3) (4) the horizontal integration end of the two-layer plastic cement of taper knob (1) is respectively made multilayer slope faying face (31) (41) (as shown in Figure 4).

(32) (42) are the multilayer slope faying faces of the two-layer plastic cement joint portion (3) (4) of taper knob (1) among Fig. 5.A-A cross section referring to Fig. 2.

Claims

1, a kind of double-deck clamp type tool taper knob, it is characterized in that taper knob is fused and constitute by the different two-layer plastic cement of hardness, the ebonite layer tightly is placed in handle, and the flexible glue layer then fuses the outside in ebonite, moreover also constitutes multilayer slope engagement shape at faying face hard, flexible glue.
