Description
Technical field
The utility model relates to a kind of aid often using in the fields such as oil, chemical industry, smelting, refers more particularly to a kind of adjustable F type spanner.
Background technology
In the workshop in oil field, the same instrument that staff often uses is exactly " F " spanner, open large gate use large, open little gate and use little, it is many that the instrument of the same race of different model not only uses, and, also have in the use the place of many inconveniences, distance between two " chuck " is non-adjustable, bayonet socket size is fixing, and the valve that runs into different model just need to be changed adaptive spanner, and pinch bar cannot carry out to field condition the situation such as change of length.This just needs, and a kind of fitness is high, economical, spanner replaces efficiently.
Summary of the invention
The utility model is intended to for the deficiency existing in background technology, and a kind of adjustable F type spanner is provided.
The adjustable F type of one of the present utility model spanner, to be formed by fixed chuck, wrench body and grip, fixed chuck has vertically been fixed in one end of wrench body, on the body of rod of wrench body, be socketed active chuck, active chuck and fixed chuck are arranged in the same way side by side, the other end pivot bush unit of wrench body is in extension sleeve, and extension sleeve has coordinated adjustment nut with the link of wrench body, and the other end of extension sleeve has been socketed grip.
As further improvement of the utility model, in wrench body, be interval with more than two locating hole.
As further improvement of the utility model, on active chuck, there is locking handwheel, the body of rod bottom of locking handwheel is sticked in locating hole.
As further improvement of the utility model, fixed chuck and active chuck two sides are inner concave arc surface.
As further improvement of the utility model, setscrew nut has been fixed in the termination of the extension sleeve in grip.
The adjustable F type of one of the present utility model spanner, reasonable in design, owing to there being active chuck, bayonet socket size is adjustable, can adapt to the valve of different model, encounters the valve that difficulty is large, can, by wrench body in the pull-out of extension sleeve part, extend the spanner arm of force, reach labour-saving object.Because adaptability is good, so need not be equipped with the spanner of Multiple Type, alleviate staff's burden, improve operating efficiency, realize the variation of instrument.Avoid the quantity of old-fashioned F spanner various different in size, caused and carry inconvenience, take care of the realistic problem difficult, cost is high.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of adjustable F type spanner of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the adjustable F type of one of the present utility model spanner is described further.
The adjustable F type of one of the present utility model spanner, to be formed by fixed chuck 1, wrench body 4 and grip 8, fixed chuck 1 has vertically been fixed in one end of described wrench body 4, on the body of rod of wrench body 4, be socketed active chuck 2, active chuck 2 is arranged in the same way side by side with fixed chuck 1, make fixed chuck 1, active chuck 2 and wrench body 4 be " F " shape, and fixed chuck 1 is inner concave arc surface with active chuck 2 two sides.
The other end of wrench body 4 is provided with external screw thread pivot bush unit in extension sleeve 6, and extension sleeve 6 has coordinated adjustment nut 5 with the link of wrench body 4, and the other end of extension sleeve 6 has been socketed grip 8.Setscrew nut 7 has been fixed in the termination of the extension sleeve 6 in grip 8, in setscrew nut 7, is provided with internal thread.
In wrench body 4, be interval with more than two locating hole 9, have locking handwheel 3 on active chuck 2, the body of rod bottom of locking handwheel 3 is sticked in locating hole 9.
The adjustable F type of one of the present utility model spanner, in use, can regulate according to the model difference of valve the position of active chuck 2, in the time that active chuck 2 is adjusted to the locating hole of relevant position, can be by the downward precession of locking handwheel 3, snap in locating hole, now between active chuck 2 and fixed chuck 1, form fixing bayonet socket, during then fixed chuck 1 is inserted into and lacks in valve, using active chuck 2 is fulcrum, wrench body 4 is the arm of force, utilizes lever principle to reach time saving and energy saving object.Running into eminence or opening and closing difficult valve, wrench body 4 can be drawn out to from extension sleeve 6 to suitable position, be fixed with adjusting nut 5, thereby back-up wrench main body 4 is reaching the object that extends the arm of force.The not used time, in wrench body 4 retraction extension sleeves 6, and is tightened wrench body 4 other ends and setscrew nut 7, shortens its length, is convenient to deposit and carry.
