Description

A kind of screw tap, die-stock

Technical field

The utility model relates to a kind of spanner, relates in particular to a kind of screw tap, die-stock.

Background technology

Existing screw tap plate, tooth spanner kind and specification have a lot, but its structure is similar substantially, generally comprised the spanner seat, be provided with screw in the spanner seat, be arranged on the handle of spanner seat both sides, handle generally is to be threaded in the spanner seat left and right sides, have through hole and the screw tap hole vertical in the spanner seat with through hole, during use, screw die or screw tap are inserted in the spanner seat, utilize the screw in the spanner seat that workpiece is carried out mantle fiber or tapping.The handle of general this spanner is the metal handle, and shorter and smaller quality is hard and smooth, and the user holds that adept handle is uncomfortable, feel is bad when operation, and skids easily, uses and requires great effort.

It is that the Chinese utility model patent " die tap combination wrench " of ZL96228139.5 (notification number is CN2256794Y) has just disclosed a kind of like this spanner that one patent No. is arranged, spanner frame, fixed handle and adjusting lead screw handle are arranged, stiff end is put the clamp of an interchangeable direction in the spanner frame, a V-arrangement slip clamp is put in the adjustable side, the lower surface that it is characterized in that interchangeable direction clamp has a projection, and a location sheet frame is fixed in the front of spanner frame.The lower surface of clamp can be plane or cambered surface.The rectangle hole of location sheet frame is more young than spanner frame.The advantage of this spanner is to finish the mantle fiber of screw die of multiple different size and the tapping of multiple screw tap.But it still exists handle to hold by defective uncomfortable, that feel is bad, use is hard.

It is the structure that the Chinese utility model patent " screw die, screw tap adjustable wrench " of ZL94246842.2 (notification number is CN2209018Y) has disclosed a kind of like this spanner that one patent No. is arranged again, it takes section to be processed with annular knurl holding of left and right sides handle, annular knurl is set increases frictional force, the defective that palmistry is skidded to handle when preventing operating handle is used laborsaving relatively.But the handle quality is still very hard, the user hold take uncomfortable, feel is bad.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of to hold by comfortable, good hand touch, use labour-saving screw tap, die-stock at above-mentioned prior art present situation, and it has advantage rational in infrastructure, easy to process.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of screw tap, die-stock, include the spanner seat, and be arranged on the handle of spanner seat both sides, it is characterized in that holding by end of described handle is coated with the sleeve made from flexible material.

The defective that palmistry is skidded to handle when preventing operating handle, the outer surface of above-mentioned sleeve forms anti-skid design.

Above-mentioned anti-skid design is good with the sags and crests that spreads on the sleeve.Certainly also can adopt the anti-skid design that is adopted on the existing sleeve.

Holding of above-mentioned handle takes end to be processed with annular knurl.Sleeve is combined firmly with handle.

Above-mentioned sleeve is that pressure injection is taken end to holding of handle.But adopt the mode sleeve of pressure injection to combine with handle firmly, be difficult for coming off from handle.

In above-mentioned sleeve also is coated on the outer face of handle.So not only make the spanner overall appearance, and can also prevent that sleeve is towards the slippage of handle inner end.

Compared with prior art, advantage of the present utility model is: it takes end to be coated with the sleeve made from flexible material holding of handle, the user is when the operation spanner like this, two hands contact soft sleeve rotating spanner more simultaneously, not only increased feel, and sleeve also has certain antiskid function, operates more laborsaving.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1～3, be an embodiment of the present utility model, it is a kind of die-stock, includes spanner seat 1, is arranged on the handle 2 of spanner seat 1 both sides, and handle 2 generally is threaded in spanner seat 1 both sides, and holding of handle 2 takes end to be processed with annular knurl 21.

Wherein spanner seat 1 can adopt various different structures, have adjustable, have multidutyly or the like, be illustrated in figure 1 as a kind of of screw tap, die-stock, it is a prior art, it is not described in detail at this.

Holding of described handle 2 takes end to be coated with the sleeve made from flexible material 3, in this sleeve 3 also is coated on the outer face of handle 2, the mode that sleeve 3 provides pressure injection is combined in holding by end of handle 2, and the outer surface of sleeve 3 forms anti-skid design 31, anti-skid design 31 also can be the anti-skid design of other type certainly for spreading over the sags and crests on the sleeve 3.

Shown in Fig. 4,5, be second embodiment of the present utility model, it is a kind of windeisen, the difference of itself and first embodiment is that the structure difference that it adopts the spanner seat is the equal of screw tap, the die-stock of another kind of model specification.
