Abstract

The utility model relates to a bidirectional ratchet socket spanner which is composed of a sleeve barrel body, a bidirectional ratchet mechanism and a special spanner. The bidirectional ratchet socket spanner is characterized in that the sleeve barrel body is provided with the bidirectional ratchet mechanism which is wrenched by the special spanner, and the sleeve barrel body can rotate in bidirection. A screw nut can be rotated in forward direction and inverse direction, and the utility model has the advantages of high speed, convenient operation, one-person operation and enough strength. The bidirectional ratchet socket spanner is widely suitable for a place which has small rotation angle and narrow space and is particularly suitable for field operations or the assembly and the disassembly of double wheels of a truck in a small store.

Description

Two-way box socket set

The utility model relates to a kind of ratchet spanner instrument, particularly relates to a kind of two-way box socket set.

Existing in the open air or place, little shop unloads or the instrument of loading truck wheel is an impact wrench, generally want two people's compounding practices, when unloading or during the loading truck wheel, rotate nut, whenever revolving certain angle will take out the arm bar other end that the sleeve pipe that strengthens the arm of force puts box spanner again and rotate to an angle, so cyclic process, unload or the speed of wheel-mounted slow, time-consuming, box spanner uses inconvenient, and its arm bar is subjected to the restriction in aperture, diameter can not be too big, when often changing the lorry dual wheels, and the arm bar insufficient strength of box spanner, the meeting bending can not unload or wheel-mounted.

The purpose of this utility model provides a kind of two-way box socket set, can rotate nut by both forward and reverse directions, and rotation nut speed is fast, and intensity is enough.

For achieving the above object, two-way box socket set of the present utility model is made up of sleeve body, the bidirectional ratchet mechanism and the spanner that are enclosed within on the sleeve body, it is characterized in that: sleeve body one end has a shape, size and hex nut, the corresponding cavity of bolt, this cavity top is a hexagon, a little bearing or copper sheathing are equipped with in the below, the other end has a shape, size and tetragonal nut, the corresponding cavity of bolt, cavity is a quadrangle, a copper sheathing is housed in the cavity, and sleeve body middle part external diameter has spline; The ratchet spline endoporus of bidirectional ratchet mechanism and sleeve body middle part spline external diameter movingly, the bidirectional ratchet mechanism end face has corresponding two through holes of two pawls of shape, size and special spanner; The two pawls of special spanner one end and two through holes of this ratchet mechanism end face have shape, size and sleeve body middle part external diameter corresponding grooves for movingly between its pair pawl.

This bidirectional ratchet mechanism, by a ratchet, be enclosed within a ratchet sleeve on the ratchet external diameter and place two ratchets and two end caps in the ratchet sleeve to form, uniform multiple tooth on the ratchet external diameter circumference, its external diameter and ratchet sleeve endoporus are movingly; Two shapes, size and ratchet, the corresponding cavity of little spring are arranged in the ratchet sleeve, and two ratchets, little springs just in time are positioned at this cavity during assembling, and two active fastening blocks are arranged on its external diameter; The end face of end cap has shape, size and the corresponding hole of ratchet projection, and ratchet projection from then on hole stretches out.

This sleeve body other end can also be that a shape, size and hex nut, the corresponding cavity of bolt are arranged, and cavity is a hexagon, and cavity is equipped with a little bearing or copper sheathing.

This ratchet mechanism can also be a single direction ratchet mechanism, it by a ratchet, be enclosed within a ratchet sleeve on the ratchet external diameter and place a ratchet and two end caps in the ratchet sleeve to form, a shape, size and ratchet, the corresponding cavity of little spring are arranged in the ratchet sleeve, and ratchet, little spring just in time are positioned at this cavity during assembling.

After adopting such structure, owing to be provided with bidirectional ratchet mechanism on the sleeve body, the two-way rotation of sleeve physical efficiency can be rotated nut by both forward and reverse directions, and speed is fast, and is easy to use, the one man operation, and intensity is enough.Be widely used in little, the narrow place of the anglec of rotation and use, be particularly useful for field or little shop and unload or adorn the use of automobile double wheel.

Below in conjunction with drawings and the embodiments the utility model is described in further detail.
