Installation sleeve, is hinged in the notch of mounting handle front end, for installing ratchet;
Described ratchet insertion is also spacing in installation sleeve, and its center is provided with regular hexagon endoporus, for rotating outer-hexagonal bolt or installing interior hexagonal spanner;
Dop is a short cylindrical pin, and it is arranged in the body of installation sleeve side by compression spring and pressing plate, is engaged, for transmitting power in the centre bore that dop front end is inserted into installation sleeve with the teeth of ratchet outer rim;
Described interior hexagonal spanner is stepped hexagonal prism and is inserted into ratchet endoporus, with the regular hexagon endoporus matched in clearance of ratchet in the middle part of it, rotates hexagon socket head cap screw for transmitting torque.
As preferred further, be inserted with bearing pin in the forked front end bilateral symmetry of mounting handle, described installation sleeve in the notch of mounting handle, is respectively equipped with the resilient pin running through bearing pin by hinge in installation sleeve both sides.
As further preferably, be provided with rectangular boss in described installation sleeve side, for installing described dop, compression spring and pressing plate.
As preferred further, described pressing plate is fixed by screws in rectangular boss outer end, for pushing down compression spring.
As preferred further, described ratchet one end is provided with annular boss, and its diameter is greater than the internal diameter of installation sleeve, to be stuck in installation sleeve side; Circlip is provided with, to realize the spacing of ratchet in ratchet other end outer rim.
As preferred further, the teeth of described ratchet are located in the middle part of its outer rim.
As preferred further, described mounting handle rear end is set with adapter sleeve, and adapter sleeve rear end is arranged with grip, so that use.
As preferred further, described interior hexagonal spanner is multiple and corresponding different hexagon socket head cap screw hole size, so that hexagonal spanner in changing according to the hexagon socket head cap screw of different size.
The invention has the beneficial effects as follows: because ratchet center is provided with regular hexagon endoporus, can be used in rotating outer-hexagonal bolt; Owing to being fitted with interior hexagonal spanner at ratchet endoporus, therefore, it is possible to for rotating hexagon socket head cap screw, for hexagon socket head cap screw and outer-hexagonal bolt all applicable; And structure is simple, component parts is few, is convenient to processing, easy to use, inserts or unload the conversion that interior hexagonal spanner just can realize between outer-hexagonal universal wrench and interior hexagonal universal wrench.

Detailed description of the invention
As depicted in figs. 1 and 2, the manual inside and outside hexagonal universal wrench of the one that the present invention relates to, comprise a mounting handle 7, its front end is forked, and rear end is shaft-like, for providing installation body.One is hinged with for installing the installation sleeve 2 of ratchet 3 in the notch of mounting handle 7 front end, bearing pin 1 is inserted with in the forked front end bilateral symmetry of mounting handle 7, described installation sleeve 2 is hinged on by bearing pin 1 in the notch of mounting handle 7, is respectively equipped with the resilient pin 11 running through bearing pin 1 in installation sleeve 2 both sides.Described installation sleeve 2 outer wall side is provided with the rectangular boss 201 of one, and rectangular boss 201 is positioned at the notch side of mounting handle 7, for installing dop 4, compression spring 5 and pressing plate 6.
Insert in installation sleeve 2 and be provided with ratchet 3, ratchet 3 center is provided with regular hexagon endoporus, for rotating outer-hexagonal bolt or installing interior hexagonal spanner 12.Described ratchet 3 one end is provided with annular boss 301, and its diameter is greater than the internal diameter of installation sleeve 2, to be stuck in installation sleeve 2 side; Circlip 13 is provided with, to realize the spacing of ratchet 3 in ratchet 3 other end outer rim.Zigzag teeth 302 are processed with, for realizing single-direction transmission screens in the middle part of ratchet 3 outer rim.
An installing hole 202 is provided with in the middle part of rectangular boss 201, described dop 4 is a short cylindrical pin, it is arranged in the installing hole 202 of described rectangular boss 201 by compression spring 5 and pressing plate 6, be engaged with the teeth 302 of ratchet 3 outer rim, for transmitting power in the centre bore that dop 4 front end is inserted into installation sleeve 2; Described pressing plate 6 is fixed on rectangular boss 201 outer face by two screws 10, for pushing down compression spring 5.
Described interior hexagonal spanner 12 is stepped hexagonal prism and is inserted into ratchet 3 endoporus, with the regular hexagon endoporus matched in clearance of ratchet 3 in the middle part of it, rotates hexagon socket head cap screw for transmitting torque.Its one end is provided with annular snap along 1201 and is stuck in annular boss 301 outer end of ratchet 3, spacing for the one direction realizing interior hexagonal spanner 12; Its other end is the hexahedron 1202 that size is less, for rotating hexagon socket head cap screw.Described interior hexagonal spanner 12 is multiple and hexagon socket head cap screw hole size corresponding to its hexahedron 1202 one end, so that hexagonal spanner 12 in changing according to the hexagon socket head cap screw of different size.
As further preferably, described mounting handle 7 rear end tight fit is set with adapter sleeve 8, is arranged with the insulation grip 9 that rubber or plastics are made, so that use in adapter sleeve 8 rear end.
During use, adjust the size of this manual inside and outside hexagonal universal wrench and interior hexagonal spanner 12 according to the bolt kind that will rotate.When needs rotate outer-hexagonal bolt, interior hexagonal spanner 12 is unloaded, utilizes the regular hexagon endoporus at ratchet 3 center just can screw or unclamp outer-hexagonal bolt; When needs rotate hexagon socket head cap screw, load onto interior hexagonal spanner 12, hold grip and pull mounting handle 7, drive ratchet 3 and interior hexagonal spanner 12 to rotate by dop 4, just internally can carry out degree of tightness by hexagonal spanner 12.
Although embodiment of the present invention are open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
