Abstract

The utility model provides a universal adjustable booster box wrench, which is composed of a concave hole ratchet wheel box, a square shaft ratchet wheel, a semicircle tooth, a direction regulating handle, a force arm, a push rod tooth, a booster rod, a handle head, a barrel body, a clamping jaw, a regulating ring, a dustproof cover, a ferrule, etc. The utility model has the advantages of simple structure, steel saving, light weight and convenient operation and carrying. The universal adjustable booster box wrench can quickly change reversible rotary directions and vertical rotary direction, and can get across obstacles on workpieces when operation. The universal adjustable booster box wrench changes diameter according to the size and different specifications of bolts, and is suitable for being used by metric and English system and non-standard bolts. The universal adjustable booster box wrench gathers a plurality of accessory functions of traditional box wrenches into one body, and is widely and universally used in various mechanical electric appliances, machine tool devices, automobiles, tractors, bicycles engineering, etc.

Description

Universal adjustable booster box wrench
The utility model relates to a kind of box spanner, particularly be a kind of universal reducing reinforcement box spanner.
Generally use known traditional shape ratchet spanner and several sleeves and annex combination in China's hardware ﹠ tools industry.How heavy this number of tools is, the waste steel, portably use inconvenience, can not change along reverse rotational direction, can not cross barrier on the workpiece in operation, especially when complex machines equipment of maintenance is installed, want frequent selectivity to change several sleeves and adapt to the operation needs, efficient is low, application number 92220131.5,92220132.3 can change along contrary direction and vertical direction of rotation, can make left and right sides clip tongue on main frame, compress the back and become and to diminish greatly, but this structure is complicated, contain behind the spring fatigue fragile, screw thread is because of being exposed at damages of damaging easily of operation outside, clip tongue lower end, inconveniently operates in stenosis.
The utility model specific aim provides a kind of further essential improvement perfect, and the weight reduction that simplifies the structure has reduced cost, the universal reducing reinforcement box spanner that service behaviour is more superior.
The utility model is achieved like this, the utility model is passed by shrinkage pool ratchet box and contains tooth square shaft ratchet on the shrinkage pool ratchet box, an end that is positioned on the shrinkage pool ratchet box is withstood ratchet with the interlock of square shaft ratchet forward by the spring band roller, pin passes ratchet holes successively, the tuning handle, cover plate connects with shrinkage pool ratchet box, other end semicircle tooth is passed by pin and is the connection of the jaw shape arm of force, push rod tooth and the interlock of semicircle tooth in the arm of force hole, the other end spindle nose of push rod tooth passes on the afterbody that spring blocked by step and is shrinkage pool, being contained open slot push rod screw withstands, the reinforcement bar connects handle head with pin, be positioned on the reinforcement rod sleeve one end outer rim through hole and contain the ball that spring base is withstood by spring, contain tooth square shaft ratchet and pass square hole cylindrical shell connection in the band, the left and right sides is positioned on the reinforcement rod sleeve one end outer rim through hole and contains the ball that spring base is withstood by spring on the cylindrical shell, contain tooth square shaft ratchet and pass square hole cylindrical shell connection in the band, left and right sides guide groove is embedded in jaw and can moves up and down on the cylindrical shell, be positioned at the adjusting ring that jaw top fluting also can move up and down around the rotation of cylindrical shell external screw thread, the jaw lower end is symmetrical V-arrangement angle face, and dust cap and lower end that the cylindrical shell upper end connects are lasso one (referring to Fig. 1).In the utility model when operation, make two jaws move up and down required position according to nut size specification rotation adjusting ring, snap in behind the bolt continuously the turn spanner with nut until tightening or back-outing.
When needs changed the jaw different size, the rotation adjusting ring makes two jaws move up and down at cylindrical shell can realize reducing.When needs change the ratchet direction of rotation, after stirring the tuning handle and driving ratchet and overcome spring pressure, make roller withstand on the opposite side interlock of ratchet back again, promptly changed direction of rotation (referring to Fig. 2).
When needs reinforcement bar and shrinkage pool ratchet box are made level and are vertically rotated, holding the handle head afterbody promotes to make cross card and push rod screw to block back another mistake to rotation forward, the push rod tooth is topped bar under acting force of the spring, the push rod tooth is separated with the semicircle tooth in arm of force hole, otherwise forward rotating the push rod screw withstands forward, the step that promotes the push rod tooth again pushes up gradually to the semicircle tooth after overcoming acting force of the spring and promptly is locked, the reinforcement bar is forwards, backwards, during promotion trend, jump out arm of force outer fringe surface respectively, with the state that slides in the chute be rotatable and spacing, pull out the reinforcement bar backward and realized the increase torsional forces, when not needing to increase torsional forces, hold handle head and promote forward, ball is dropped on the arm of force shrinkage pool again, promptly return to original state (referring to Fig. 1).
The utlity model has simple in structure, portably use conveniently, can change fast along being locked after reverse rotational direction and ratchet box and the vertical direction of rotation of reinforcement bar, realize to cross barrier on the workpiece in the operation, adapt to metric and English, non-standard different size bolt clamping, concentrate several annexes of conventional sleeve spanner integrated, save steel, weight reduction has reduced cost.
