Description

Fitting for multifunctional combined fastening wrench

The utility model relates to a kind of hand tools of dismounting securing member, promptly multi-functional fastening combination wrench annex.

The design people has a patent of having authorized " multifunctional combination wrench " (patent No. 912134174.1), the characteristics of this combination wrench are to utilize a kind of crossover sub to be connected use with monkey wrench, bulldog wrench and ratchet spanner etc., but can't realization and being used in combination of items such as open-end wrench, double offset ring spanner, inner hexagon spanner, box spanner, be subjected to some restrictions in actual applications.

The utility model proposes a kind of new additional project at above-mentioned shortcoming, makes open-end wrench, and double offset ring spanner, inner hexagon spanner, box spanner etc. can be used with intrinsic multifunctional combination wrench.The crux that addresses this problem is to the utility model proposes a kind of new crossover sub that can be used with multifunctional combination wrench, this crossover sub can be used in combination with open-end wrench or double offset ring spanner, the design also proposes a sleeve the core of the card on the other hand, be connected with the crossover sub of former design multifunctional wrench by the sleeve the core of the card and solved the be used in combination problem of inner hexagon spanner, thereby make the function of intrinsic multifunctional combination wrench more complete with box spanner.

Details are as follows in conjunction with the accompanying drawings for the design, wherein:

Fig. 1 is crossover sub (a 1) schematic diagram;

Fig. 2 is an inner hexagon spanner sub-assembly schematic diagram;

Fig. 3 is a sleeve extension bar sub-assembly schematic diagram;

Fig. 4 is an open-end wrench sub-assembly schematic diagram;

Fig. 5 is a double offset ring spanner sub-assembly schematic diagram;

Fig. 6 is a box spanner sub-assembly schematic diagram;

Fig. 7 is the handle connection layout of double offset ring spanner and open-end wrench and multifunctional combination wrench;

Fig. 8 is the handle connection layout of sleeve and multifunctional wrench;

Fig. 9 is the handle connection layout of inner hexagon spanner and multifunctional wrench;

Figure 10 is a sleeve the core of the card schematic diagram.

There is a square groove (1b) top of crossover sub (1) as seen from Figure 1, connector (7a) for multifunctional wrench handle (7) inserts (see figure 7), and, just in time be complementary and make tie point (7a) more tight with being connected of crossover sub (1) with the concave point (7b) of connector (7a) owing on the groove walls decorative pearl on top of an official cap (1c) that spring (1d) withstands is housed.The below of crossover sub (1) has a rectangle projection (1a) can insert in the connecting hole (5a) of the connecting hole (4a) of open-end wrench (4) and double offset ring spanner (5), also be provided with spring top bead (1e) in the above-mentioned projection (1a), the decorative pearl on top of an official cap (1e) just with open-end wrench connecting hole (4a) in concave point (4b) and the concave point (5b) of double offset ring spanner connecting hole (5a) mate to fix both connection.

Figure 10 represents a newly-designed sleeve the core of the card (8), sleeve the core of the card (8) is that a centre has folder metal plate (8a), respectively there is a hex socket (8b and 8c) at two ends, the external diameter of two sleeves has nothing in common with each other up and down, the crossover sub (9) of the external diameter of upper bush (8b) and former design multifunctional combination wrench be complementary (detail of crossover sub (9) is described and seen 912134174.1 patent specifications) wherein, and can insert connecting hole (9a) (see figure 8) of intrinsic crossover sub (9), its lower sleeve then is connected with the insertion end (6a) of the sleeve (6) of other all size, just can use.But when the working face of nut hour, (3a) of also available extension bar (3) as shown in Figure 3 inserts connecting hole (9a), is used at the sleeve of other end side and various different sizes.

When sleeve the core of the card (8), can and use as inner hexagon spanner the lower sleeve (8b) of the insertion end of inner hexagon spanner (2) (2a) insertion sleeve the core of the card when striking up partnership as shown in Figure 9 through intrinsic crossover sub (9).

The design can make intrinsic multifunctional combination wrench increase as open-end wrench after as the annex of former design multifunctional combination wrench, and the function of double offset ring spanner, inner hexagon spanner and box spanner makes its tool more perfect function, uses convenient.

Claims (1)

1, a kind of multifunctional combination wrench annex, of the present utility model being characterized as: (a), there is a groove (1b) that can insert for the connector (7a) of multifunctional combination wrench handle (7) top of crossover sub (1), its below is the projection (1a) that can be connected with double offset ring spanner or open-end wrench; (b), sleeve the core of the card (8) is to have in the middle of one folder metal plate (8a) connector of (8b and the 8c) of a hexagon sleeve respectively to be arranged two ends up and down; (c), middle part is provided with the open-end wrench (4) of connecting hole (4a); (d), a kind of middle part is provided with the double offset ring spanner (5) of connecting hole (5a); (e), has the inner hexagon spanner (2) of insertion end (2a) and have the box spanner (6) of insertion end (6a).
