Abstract

The utility model relates to a multipurpose adjustable wrench which comprises a wrench handle 1, and a wrench body 7 which is arranged on one end of the wrench handle 1 and is provided with a death tongue 3. A tongue seat 9 of which the bottom is provided with screw threads 10 is arranged on the wrench body 7, and a thread screw rod 2 matched with the screw threads 10 and arranged on the wrench body 7 can make the tongue seat 9 move. A movable tongue 6 is connected with the upper part of the tongue seat 9. After the utility model is interlocked and a definite angle is screwed, the wrench which can be screwed continuously does not need to be off a screwed cap 4 again and again. The work efficiency is enhanced, and a skidding phenomenon can not appear when the utility model is screwed.

Description

Multiple adjustable wrench

The utility model discloses a kind of Multiple adjustable wrench, belong to hand tools.

Existing adjustable wrench, because its moving tongue is to constitute with the tongue seat one of threaded of lower end, its work is by stirring the screw rod that matches with the screw thread bar on the wrench body, whole tongue seat is moved, and cooperates with tongue extremely and bites by stubborn nut thereby reach moving tongue.In the process of turning, two inner edges of jaw must remain parastate ground interlock nut.And turning in the process after interlock, whenever twist certain angle, spanner must be recessed nut, and then interlock.Thereby can not realize turning continuously after interlock, so operating efficiency is low; Also have, this spanner is prone to tightly not cause with the nut interlock and skids and damage nut.

Task of the present utility model is to provide the arbitrary position of a kind of nut can enter spanner mouth and the operating efficiency height that just can turn continuously once interlock, the Multiple adjustable wrench that is difficult for skidding.

Task of the present utility model is finished like this, a kind of Multiple adjustable wrench, it comprises spanner handle 1 and is positioned at the wrench body 7 with a dead tongue 3 of spanner handle 1 one ends, be separately positioned on its threaded 10 tongue seat 9 in bottom on the wrench body 7 and the thread screw 2 that tongue seat 9 is moved that matches with screw thread bar 10, the movable lug 6 that connects on the top of tongue seat 9.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is the utility model topology view.

Movable lug 6 of the present utility model and tongue seat 9 is active the connection, and expense hole respectively on tongue seat 9 and movable lug 6 is connected movable lug 6 by movable lug pin 8 then with tongue seat 9 earlier, makes movable lug 6 swing back and forth certain angle and reach the opening angle of flexible change jaw 5 around movable lug pin 8.Tongue seat 9 is arranged in the elongated slot on the wrench body 7 by its underpart, and the bottom one of tongue seat 9 is processed with screw thread bar 10, and screw thread bar 10 matches with the thread screw 2 that is located on the wrench body 7 by screw shaft 11.During work,, move, make the movable lug 6 of loose joint on tongue seat 9 cooperate dead tongue 3 interlock nuts 4 thereby make in the groove of tongue seat 9 on wrench body 7 by screw thread bar 10 with the moving thread screw 2 of hand-lifting.Because when movable lug 6 opened, dead tongue 3 was the little taper state of outer imperial palace with movable lug 6 formed jaws 5, promptly the size of jaw 5 is greater than nut 4.Thereby when work, be convenient to interlock nut 4 and unclamp spanner; In addition, because the angle swinging of movable lug 6 can play guide effect, as long as handle 1 is done a little low-angle automatic swing, just can make the S limit interlock of dead tongue 3 and nut 4, can hit to movable lug 6 bottoms, because leverage, it is in place and nut 4 stung tightly enter duty that movable lug 6A moves to movable lug 6 positions.When pulling handle 1 certain angle, nut 4 is just corresponding to rotate to an angle, and when spanner withdraw from very a little bit smaller apart from the time, because nut 4 still is in the nut 4A position in the jaw 5A, can make reciprocal spanner handle 1 certain angle of pulling so need not make spanner break away from nut 4 fully, at this moment nut 4 is touched the inner edge of movable lug 6 and is become the inner edge that the D edge joint touches movable lug 6A gradually by former S edge joint, thereby promote movable lug 6 opened with certain angle to movable lug 6A position, repeating above-mentioned steps then just can screw nut 4 fast or unscrew, when pulling handle 1, one thrust is arranged at 4 pairs of movable lug 6 bottoms of nut, make movable lug 6 sting the S limit of tight nut 4 more firmly, thereby skidding can not appear in nut 4.

The utility model is because active the connection can be around the movable lug 6 of movable lug pin 8 swings in the upper end of tongue seat 9, so nut 4 any positions can enter jaw 5, when movable lug 6 is bitten nut 4 once the dead tongue 3 of cooperation, need not after turning certain angle, make spanner recess nut 4 repeatedly and can turn continuously, improve operating efficiency, and in the process of turning, skidding can not occur.

Claims (1)

1, a kind of Multiple adjustable wrench, it is characterized in that it comprises spanner handle (1) and is positioned at the wrench body (7) with a dead tongue (3) of spanner handle (1) one end, be separately positioned on the tongue seat (9) of its bottom threaded (10) on the wrench body (7) and the thread screw (2) that tongue seat (9) is moved that matches with screw thread bar (10), the movable lug (6) that connects on the top of tongue seat (9).
