In order to achieve the above object, the utility model proposes a kind of ratchet spanner structure, it comprises:

One handle, an end of this handle has a ratchet head, the inner installing of this ratchet head one ratchet structure, and the end face of this ratchet head installs a pallet, and this pallet is switched this ratchet structure;

One hollow operating sleeve, this operating sleeve are to be installed in this ratchet head, and the desired location of this operating sleeve is provided with two or more screw;

Two or more location group, each location group are to be installed in respectively in the screw of this operating sleeve;

Two or more spiral lock, each spiral lock are that spiral shell is located in this screw respectively, and are kept out each location group.

Wherein, this operating sleeve is a hexagonal configuration in the hollow.

Wherein, this location group is made up of a spring and a steel ball, and an end of this spring abuts against the side in this spiral lock, and the in addition end of this spring replaces this steel ball, makes protruding this operating sleeve inside of exposing of this steel ball.

Wherein, this location group is made up of a spring and a steel ball, and an end of this spring is a side that abuts against in this spiral lock, and the in addition end of this spring replaces this steel ball, makes that this steel ball is protruding to be exposed outside this operating sleeve.

Wherein, this spiral lock is a screw.

Wherein, further comprise a hollow first auxiliary socket, the outer peripheral edges of this first auxiliary socket are provided with some recessed edge, and this first auxiliary socket is to be installed in this operating sleeve, make this steel ball be resisted against this recessed edge.

Wherein, further comprise a hollow second auxiliary socket, the periphery desired location of this second auxiliary socket is provided with a perforation, and this second auxiliary socket is to be installed in outside this operating sleeve, makes this steel ball be resisted against this perforation.

Advantage of the present utility model and effect are: a kind of increase operating efficiency is provided, and the ratchet spanner structure of handled easily use; A kind of assembling, replacing time of reducing sleeve is provided, and reduces the ratchet spanner structure of purchasing different size sleeve cost.

[specific embodiment]

Please cooperate and consult shown in Fig. 1-7, the utility model is a kind of ratchet spanner structure, and it comprises:

One handle 10, an end of this handle 10 has a ratchet head 11, this ratchet head 11 inner installing one ratchet structure (not shown), and the end face of this ratchet head 11 installs a pallet 12, and this pallet 12 is switched this ratchet structure;

One hollow operating sleeve 20, this operating sleeve 20 are to be installed in this ratchet head 11, and the desired location of this operating sleeve 20 is provided with two or more screw 21;

Two or more location group 30, each location group 30 are installed in respectively in the screw 21 of this operating sleeve 20;

Two or more spiral lock 40, each spiral lock 40 spiral shell respectively are located in this screw 21, and are kept out each location group 30.

Wherein, this operating sleeve 20 is a hexagonal configuration in the hollow.

Wherein, this location group 30 is made up of a spring 31 and a steel ball 32, and an end of this spring 31 abuts against the side in this spiral lock 40, and the in addition end of this spring 31 is to replace this steel ball 32, makes this steel ball 32 protruding this operating sleeve 20 inside of exposing.

Wherein, this location group 30 is made up of a spring 31 and a steel ball 32, and an end of this spring 31 abuts against the side in this spiral lock 40, and the in addition end of this spring 31 is to replace this steel ball 32, makes 32 protruding exposing outside this operating sleeve 20 of this steel ball.
