Detailed Description

The principles and features of the present invention are described below in conjunction with the following examples, which are set forth only for the purposes of explanation and are not intended to limit the scope of the present invention.

As shown in fig. 1-4, a narrow and small space spanner of straight cylinder, including shell 1, be equipped with action wheel 2 in the shell 1 and follow driving wheel 4, action wheel 2 and from driving wheel 4 intermeshing, the central point that corresponds two gears on the shell 1 puts and is equipped with the hole, locates the bottom from the hole of 4 one ends of driving wheel, and the top is located in the hole of 2 one ends of action wheel, be equipped with the support on the shell 1 of 2 one ends of action wheel, be equipped with straight-bar 5 from 4 middle parts of driving wheel, straight-bar 5 with from 4 fixed connection of driving wheel, the other end of straight-bar 5 is equipped with nut 6, the central point of action wheel 2.

In order to facilitate replacement of different nuts 6 and adapt to tightening of different bolts, the straight rod 5 is bolted with the nuts 6, holes are formed in the straight rod 5 and the nuts 6 in the diameter direction, bolts 7 penetrate through the holes, and the nuts 6 of different specifications can be arranged, so that bolts of different specifications can be conveniently tightened.

For guaranteeing the stability of spanner, the support includes base 8 and locates telescopic link 9 on the base 8, the interior pole of telescopic link 9 with 1 fixed connection of shell.

In order to take down the handle 3 and facilitate installation, a connecting hole 10 is formed in the middle of the driving wheel 2, grooves 11 are symmetrically formed in the connecting hole 10, the handle 3 is a Z-shaped handle, a connecting shaft 12 is arranged at one end of the handle 3, and clamping pins 13 are arranged on the connecting shaft 12 and used for limiting relative rotation of the handle 3 and the driving wheel 2.
