Abstract

The utility model relates to a tap wrench with screw dies. The utility model is composed of a wrench body, two handles, a V-shaped clamping block, a W-shaped clamping block, a holding screw and male pins. A stepped hole is arranged in the wrench body, and the holding screw is arranged on one side wall of the stepped hole. Two sections of guiding grooves are also arranged in the wrench body along a handle axis, the V-shaped and the W-shaped clamping blocks which are sheathed on the end of the handle are respectively arranged in the guiding groove, and the male pins on the clamping blocks pass through an annular notch on the end of the handle. The utility model integrates functions of a tap and the cutting die, which is convenient for operating and carrying.

Description

A kind of screw tap die-stock

The utility model relates to a kind of screw tap die-stock, and this spanner can be used for tapping or mantle fiber.

The previously manual machining internal thread need use two different spanners during with external screw thread, very inconvenient, Chinese patent specification CN2134251Y discloses a kind of combined type screw tap die-stock, the function of screw tap, die-stock is combined together, but its complex structure, use inconvenient.

The purpose of this utility model is to provide a kind of screw tap die-stock easy to use.

For achieving the above object, screw tap die-stock of the present utility model is made up of wrench body, two handles, V-arrangement fixture block, W shape fixture block, pin and holding screw, two handles are threaded with the two ends of wrench body, one shoulder hole that is used to install screw die is arranged in the wrench body, the macropore sidewall of shoulder hole is provided with the holding screw that is used for fixing screw die, in wrench body, also have two sections gathering sills along the handle axis direction, be furnished with the V-arrangement and the W shape fixture block of the handle end of being enclosed within the groove respectively, the pin on the fixture block passes the annular recess on the handle end.

After adopting such structure, shoulder hole can be installed the screw die of same outer diameter as different inner diameters, carries out mantle fiber; Turning handle can promote V, W shape fixture block is clamped screw tap and carried out tapping, uses very convenient.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Among Fig. 1: two handles 1,2 are threaded with wrench body 3 two ends respectively, and its end is with V-arrangement fixture block 4 and W shape fixture block 5 respectively.There is a shoulder hole 6 at wrench body 3 middle parts, have screw 7 on the macropore hole wall.As shown in Figure 2, in wrench body, have two sections gathering sills 8,9, intersect with shoulder hole 6 respectively along the handle axis direction.Be furnished with V-arrangement fixture block 4 and W shape fixture block 5 in the groove respectively, the pin 10 on the fixture block passes the annular recess of handle end.In the screw 7 of ladder hole wall holding screw 11 is housed.

During use, the screw tap that rotary handle promotion V, W shape fixture block can be clamped multiple model carries out tapping; Fixture block is retreated in the groove, screw die can be installed in shoulder hole, get final product mantle fiber after clamping with holding screw.Screw die can use identical and the multiple model that internal diameter is different of external diameter.
