Description
Technical field:
The utility model relates to spanner technical field, specifically a kind of for Large circular cylinder degree of tightness spanner.
Background technology:
The device of the cast on the large-scale face of cylinder links together often through the connected mode of screw thread, and on the face of cylinder that these are relatively large the more difficult shape being arranged to nut, the spanner of so large nut is not had yet, such as in the field that pipeline connects, in the field etc. of air filter for automobile dismounting, what the spanner of the degree of tightness for this connected mode of the prior art had is contacted by the hard of metal with the face of cylinder, easily on the face of cylinder, leave impression, even cause distortion, also the snap fit with soft ribbons is had plenty of, but need the grip force that staff is larger, otherwise just cause coming loose of soft ribbons, do not have the effect of card labor, existing spanner of the prior art can not regulate the engaging diameter of spanner preferably for the face of cylinder that diameter changes greatly in addition.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, and be convenient to regulate, card labor is reliable and stable, and labour-saving is used for Large circular cylinder degree of tightness spanner.
Solve technical problem adopt following technical scheme:
A kind of for Large circular cylinder degree of tightness spanner, it is characterized in that: comprise gland, fastening belt, leading screw, silk braid, fixed cover and handrail, described gland is symmetrically arranged with two elongated holes, the two ends of described fastening belt are inserted in elongated hole respectively from the front end of gland, described leading screw is fixedly installed on the rear end of gland, described silk braid is threaded connection and is set on leading screw, described fixed cover is rotatable relative to silk braid to be arranged on silk braid, the two ends of described fastening belt are fixedly installed on fixed cover, described handrail is fixedly installed on the end of leading screw.
The inner side of described fastening belt is evenly provided with jagged anti-slip veins.
The front end of described gland is provided with the groove of circular arc.
The sidepiece of described silk braid is provided with symmetrical handle.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, are convenient to regulate, and card labor is reliable and stable, can not cause damage to the face of cylinder, and without the need to grip force.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
