Abstract
The utility model belongs to tools used for fastening or loosening bolts and nuts, and relates to a wrench, in particular to a hexagonal ratchet sleeve wrench which comprises a wrench body and a sleeve provided with a ratchet, the sleeve provided with the ratchet is connected to one end of the wrench body in a matched mode, the sleeve is a hexagonal sleeve, an outer surface of a port position of a work end of the sleeve is a slope, and the included angle of the slope and an inner side wall of the sleeve is 40-60 degrees. Contact surfaces of the wrench sleeve and a nut are increased, so that the nut is not easy to damage; the sleeve and the nut are easy to fit, so that operation is convenient, and work efficiency is improved.
Description
Technical field
The utility model belongs to the instrument of tightening or unscrew screw, nut, i.e. spanner; Be particularly related to a kind of hexagonal box socket set.
Background technology
Ratchet spanner with respect to common wrench, on the convenience of its use, has absolute advantage, during its rotation nut, need not to take off spanner, only needs the reverse rotation spanner can accomplish the rotation of the nut of next segment distance; Yet it is the same with common wrench, and the wall thickness of sleeve makes spanner under the situation that the gap narrows down gradually between rotation nut and the workpiece wall, and wrench socket can't contact with nut fully; When the rotation nut; Less contact-making surface makes nut damage easily, and is inconvenient to operate, and operating efficiency is not high.
Summary of the invention
The utility model provides a kind of ratchet spanner, and purpose is to solve existing ratchet spanner, because the sleeve influence of wall thickness makes sleeve and nut contact-making surface little, nut is fragile, and causes inconvenient operation, ineffective defective.
The utility model comprises wrench body, is provided with the sleeve of ratchet; The said sleeve that is provided with ratchet is connected at an end of said wrench body; Said sleeve is a Hexagonal jacket; The outer surface of the port of the working end of said sleeve is arranged to the inclined-plane, and the angle between said inclined-plane and the sleeve madial wall is 40 °～60 °.
The utility model is through being arranged to the inclined-plane with the outer surface of the port, working end of sleeve; Be about to port wall thickness attenuation; Like this can be so that under the situation that wrench socket can narrow down in the gap between nut and the workpiece gradually; Can increase the contact-making surface of sleeve and nut, make nut not fragile like this; Sleeve and nut are prone to coincide, also can be so that operation become convenient, and operating efficiency improves.
Angle between said inclined-plane of the utility model and the sleeve madial wall is 45 °～50 °.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is a kind of structural representation of the utility model sleeve;
Fig. 3 is that the A-A of Fig. 2 is to view.
Among the figure, 1, wrench body, 2, sleeve, 3, the inclined-plane, 4, ratchet.
The specific embodiment
Like Fig. 1,2, shown in 3; This ratchet spanner comprises wrench body 1, is provided with the sleeve 2 of ratchet 4, and the sleeve 2 that is provided with ratchet 4 is connected at an end of wrench body 1; Sleeve 2 is a Hexagonal jacket; The outer surface of the port of the working end of sleeve 2 is arranged to inclined-plane 3, and the angle between inclined-plane 3 and sleeve 2 madial walls is 40 °～60 °, preferred 45 °～50 °.
Claims (2)
1. ratchet spanner; It is characterized in that the sleeve that comprises wrench body, be provided with ratchet; The said sleeve that is provided with ratchet is connected at an end of said wrench body; Said sleeve is a Hexagonal jacket, and the outer surface of the port of the working end of said sleeve is arranged to the inclined-plane, and the angle between said inclined-plane and the sleeve madial wall is 40 °～60 °.
