Abstract

The utility model provides a turning structure of a porous wrench. A porous sleeve wrench head and a porous offset ring wrench head can rotate randomly along the axis of a handle so that the rotational angle of the wrench head can not be fixed, which causes inconvenience in operation and is necessary to make improvement. In the utility model, a positioning sleeve and a hole are additionally formed at the maneton or the porous sleeve wrench head or the porous offset ring wrench head; a spring and two steel balls are arranged in the hole; and a plurality of positioning holes are formed on the positioning sleeve. A tight positioning hole is formed on the positioning sleeve, a slit penetrates the tight positioning hole, and the set screw of the handle can enter the tight positioning hole. The positioning sleeve is fixed in the handle by the set screw, so that when the porous sleeve wrench head or the porous offset ring wrench head is rotated, the steel balls enter and go out of the positioning holes of the positioning sleeve, thereby serving the purposes of adjusting the angle of the wrench head and positioning.

Description

Porous spanner steering structure

Affiliated technical field

The utility model is the structure about a kind of hardware ﹠ tools, knows clearly it, is a kind of porous spanner steering structure.

Background technology

Number of patent application 200820176994.2 be a kind of integrate eight pull the hole pull the borehole jack barrel spanner more, as shown in Figure 1.Be characterized in that handle 1 two ends respectively are provided with a porous sleeve spanner 2, the axis that porous sleeve spanner 2 can thorny handle 1 rotates.The situation of the porous plum blossom spanner 3 that the patent No. 88201831 Multi-end spanners are contained also is such (see figure 2).Find such defective in actual the use: after screw 4 was loosening a little, porous sleeve spanner or porous plum blossom spanner can rotate by random thorny arbor line, and the angle that spanner rotates can't be determined (to see Fig. 3-Fig. 7).Inconvenience to some extent is necessary to improve in operation.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides the location structure that a kind of spanner rotates.

The utility model is achieved in that it is to set up a positioning sleeve and a hole at the axle journal place of described each porous sleeve spanner or porous plum blossom spanner; The mid-spring in hole, two steel balls; Locate sheathed some locating holes.Positioning sleeve is provided with a tightening hole, and the tightening hole is passed in a slit, and the holding screw in the handle can enter in the tightening hole.Because positioning sleeve is fixed in the handle by holding screw, rotate porous sleeve spanner or porous plum blossom spanner, steel ball is under the effect of spring, and the locating hole of turnover positioning sleeve has played adjusting spanner angle and positioning action.

The beneficial effects of the utility model are: the angle of spanner obtains effectively determining, is convenient to operating personnel's operation.

The specific embodiment

Set up a positioning sleeve 7 and a hole 22 on the axle journal 21 of (seeing Fig. 8 and Figure 11) porous sleeve spanner 2 (or porous plum blossom spanner); Contain 52, two steel balls 51 of a spring in the hole 22; Positioning sleeve 7 contains some locating holes 73.Positioning sleeve is provided with 72, one slits 71, a tightening hole and passes tightening hole 72, and the holding screw 4 in the handle 1 can enter in the tightening hole 72.The effect in slit 71 is equivalent to make positioning sleeve 7 to have elasticity, and positioning sleeve 7 can place handle 1 very close to each otherly.Certainly, also can not establish slit 71.Because positioning sleeve 7 is fixed in the handle 1 by holding screw 4, rotate porous sleeve spanner or porous plum blossom spanner, steel ball 51 is under the effect of spring 52, and the locating hole 73 of turnover positioning sleeve 7 has played adjusting spanner angle and positioning action.

Claims

1, a kind of porous spanner steering structure, it comprises the holding screw in porous sleeve spanner or porous plum blossom spanner and handle and the handle, it is characterized in that setting up a positioning sleeve and a hole at the axle journal place of described porous sleeve spanner or porous plum blossom spanner; The mid-spring in hole, two steel balls; Locate sheathed some locating holes.

2, porous spanner steering structure as claimed in claim 1 is characterized in that described positioning sleeve is provided with a tightening hole, and the tightening hole is passed in a slit, and the holding screw in the described handle can enter in the tightening hole.
