For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of fine stern double-end ratchet wrench, its side's of comprising tenon, ratchet, ratchet and handle, described side's tenon is arranged on ratchet, described ratchet and pawl is engageable, described ratchet and pawl all is installed on handle, it also comprises positioning ball, spring and poined afterbody, in the groove that described spring fitting is provided with in handle, described positioning ball one side is connected with spring, opposite side is connected with a side of ratchet, and described poined afterbody is positioned at the handle afterbody.
Described side's tenon comprises first party tenon and second party tenon, and described first party tenon is different with the second party tenon structure.
Described ratchet comprises body, the first Contact Tooth section, the second Contact Tooth section, location division, bearing pin and installation through hole, described the first Contact Tooth section, the second Contact Tooth section and location division all are arranged at body, described the first Contact Tooth section is arranged at the upper end, left side of body, the second Contact Tooth section is arranged at the lower end, left side of body, described location division is arranged at the right side of body, described bearing pin and the socket of installation through hole.
Described the first Contact Tooth section and the second Contact Tooth section all can mesh with ratchet, and described location division is connected with positioning ball.
Described fine stern double-end ratchet wrench also comprises back-up ring, and described back-up ring is connecting handle and ratchet respectively.
be compared with the prior art, the beneficial effects of the utility model are: hook tooth of the present utility model and pawl teeth are larger, intensity is good, can not be damaged to hook tooth or ratchet even overexert yet, and special ratchet and pawl structure makes along reversing to all realizing, only need to rotate ratchet with hand, make to mesh between ratchet the first Contact Tooth section and the second Contact Tooth section and hook tooth to change and get final product, no matter also nut degree of tightness, singlehanded handle is not shifted, just rapid clockwise arbitrarily, contrary ratchet tightly unloads nut, the poined afterbody that the utility model also is provided with makes the arm of force increase, moment can increase several times, more laborsaving, fine stern double-end ratchet wrench of the present utility model is simple in structure, part is few, poined afterbody also can be used as ripping bar and uses, diverse in function, be more suitable for wide popularization and application.
As preferably, described side's tenon comprises first party tenon and second party tenon, and described first party tenon is different with the second party tenon structure, and both sides' tenon arranges, and makes the scope of application wider.
As another preferred, described ratchet comprises body, the first Contact Tooth section, the second Contact Tooth section, location division, bearing pin and installation through hole, described the first Contact Tooth section, the second Contact Tooth section and location division all are arranged at body, described the first Contact Tooth section and the second Contact Tooth section are arranged at body one side, described braking parts is arranged at the body opposite side, described bearing pin and the socket of installation through hole, make along reversing to all realizing, need not to take off, no matter also nut degree of tightness, singlehanded handle is not shifted, and just rapid clockwise, contrary ratchet tightly unload nut arbitrarily.
