The utility model discloses a with being equipped with trepanning, lower channel on the spanner body and going up the channel, be equipped with top shoe and screw rod on the slider, the swivel nut is installed in the middle of the trepanning, and the sleeve gasket is still installed to the swivel nut both sides, and swivel nut and the same shaft fit of screw rod, top shoe lie in the channel, and lower screw rod lies in channel down, can make the spanner pass through the swivel nut adjustment, is difficult for producing oil pollution, but also can effective protection point.
Description
[technical field]
The utility model relates to the technical field of tightening device, particularly the technical field of a kind of spiral shell cover spanner.
[background technology]
Along with the continuous progress of science and technology, various mechanical means is used for social production work, different equipment has different purposes, though equipment complexity of a great variety, it be unable to do without some and simply load and unload principle, and it is ubiquitous to be threaded in mechanical means, need the dismounting equipment to be, it is often necessary to use spanner, good spanner can fast and easy dismounting fastening, increase work efficiency, the routine maintenance of production unit is abnormal important. The spanner of common use, secure component is by a worm screw rack mechanism, but needs to add lubricating oil between the worm screw of centre and tooth bar, it may also be useful to time easily produce oil pollution, and worm screw tooth bar is outside exposed, may snap into finger because of carelessness during finger rotary worm.
[practical novel content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed to a kind of spiral shell cover spanner, it is possible to makes spanner by spiral shell cover adjustment, not easily produces oil pollution, and can also available protecting finger.
For achieving the above object, the utility model proposes a kind of spiral shell cover spanner, comprise wrench body, slide block, spiral shell cover and cover pad, described wrench body is provided with trepanning, Xia Cao Dao Heshangcao road, and described slide block is provided with slide block and screw rod, and described spiral shell cover is arranged in the middle of trepanning, described spiral shell cover both sides are also provided with cover pad, described spiral shell cover coordinates with screw coaxial, and described upper slide block is positioned at Shang Cao road, and described lower screw rod is positioned at Xia Cao road.
As preferably, described trepanning is greater than spiral shell cover, described cover pad, between cover hole wall and spiral shell overlap, has gap between described spiral shell cover and cover pad.
As preferably, described slide block being also provided with link arm, being connected to side by link arm between described upper slide block and screw rod, screw rod 2 is provided with screw thread.
As preferably, described spiral shell cover cylindrical is also provided with and rolls tooth, has gap between described spiral shell cover and trepanning.
The beneficial effects of the utility model: the utility model by being provided with trepanning, Xia Cao Dao Heshangcao road by wrench body; slide block is provided with slide block and screw rod; spiral shell cover is arranged in the middle of trepanning; spiral shell cover both sides are also provided with cover pad, and spiral shell cover coordinates with screw coaxial, and upper slide block is positioned at Shang Cao road; lower screw rod is positioned at Xia Cao road; spanner can be made by spiral shell cover adjustment, not easily produce oil pollution, and can also available protecting finger.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
