The invention is further provided with: each triangular slide block is equal to a waist triangle and is subjected to corner cutting treatment at one corner far away from the bottom edge to form an isosceles trapezoid.
Through adopting above-mentioned technical scheme for the sliding space of triangle slider in the sleeve is bigger, and the adjustable scope of opening that forms between the triangle slider is bigger.
By adopting the technical scheme, the sleeve cover is detachably connected with the sleeve through the plurality of connecting bolts.
Compared with the prior art, the invention has the following beneficial effects:
firstly, the chutes connected into a regular polygon drive the triangular slide block to move regularly during rotation to form an air cannon type opening, the size of the air cannon type opening can be adjusted at will according to actual conditions, the air cannon type opening is suitable for bolts and nuts of different models and sizes, trouble in finding tools is avoided, working efficiency is improved, face-to-face contact stress is realized, stress is uniform, slipping is not easy to occur, and the bolts and nuts are not easy to damage;
secondly, due to the self-locking principle of the worm wheel driving turntable and the worm, the worm can drive the worm wheel driving turntable to rotate so as to freely adjust the size of the opening of the wind cannon, but the reaction force generated when the bolt or the nut is screwed cannot enable the worm wheel driving turntable to drive the worm to rotate, and the wind cannon cannot slip due to the enlargement of the opening of the wind cannon in the using process;
thirdly, because the handle and the sleeve cover can be detached at any time, the handle can be continuously taken down to adjust the position when in use, the bolt or the nut does not need to be screwed by rotating the handle for a whole circle, and the use in a narrow and small use space is convenient.
