Description

Multifunctional wrench

Technical field:

The utility model relates to a kind of multi-functional wrench, belongs to the machine tool field.

Background technology:

Present lathe worker has a lot, and the instrument of special purpose is arranged, and multi-functional instrument is also arranged, but all has defective in various degree, makes its casing volume carry inconvenience greatly owing to exchangeable part as multi-functional instrument.And single instrument a large amount of instrument of needs when work, the time that makes repairing is than the labour intensity of growing and increased service worker.

Summary of the invention:

The purpose of this utility model is to provide a kind of multi-functional wrench, and it carries with very easy to use, and can accomplish continuously to press down and lift, and is more laborsaving during use; Shorten working time and reduced labour intensity.

The technical solution of the utility model is achieved in that multi-functional wrench is made up of handle and driving head, and wherein handle is hollow, innerly by screw thread screwdriver is housed fixedly; Driving head is made up of round axle and axle sleeve, and the external diameter of interior axle is 45 or 90 gears, and inner axes is hollow, four jiaos or hexangle type; The one side of outer shaft is fixing jam, and another side is dismantled and assembled jam, and that be equipped with the both sides of outer shaft is very heavy, spring and fix with screw, in very heavy can directly packing in the gear grooved of axle.

Good effect of the present utility model is a kind of multi-functional wrench, and it carries and uses more conveniently, has shortened working time and has reduced labour intensity.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model A-A profile;

The specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing: multi-functional as shown in Figure 1, 2 wrench is made up of handle 1 and driving head 2, and wherein handle 1 is hollow, and screwdriver 3 fixedly is equipped with by screw thread in inside; Driving head 2 is made up of axle 4 and outer shaft 5 in round, and the external diameter of interior axle 4 is 90 or 45 gears 6, and inner axes is hollow, four jiaos or hexangle type; The one side of outer shaft 5 is fixing jams, and another side is dismantled and assembled jam 7, and there is hole the both sides of outer shaft 5 and very heavy, spring is housed therein and fixes with screw.When multi-functional wrench as shown in Figure 1 uses, at first the casing joint on the interior axle 4 being chosen as required is with hollow, four jiaos or hexangle type, turning handle 1 can carry out spacing reaching by the gear 6 on the very heavy internal axle 4 in the outer shaft 5 and press down continuously and lift, so that maintenance work is finished rapidly.When needs only need during with screwdriver the screwdriver in the handle is screwed out and can use, when extending if desired screwdriver is screwed in it is become one, can do boosting-rod and use.
