Abstract

The utility model relates to an improved wrench which comprises a main body, a pressing member, a sliding block and a fine tuning member. Because the sliding block for adjusting the distance of the fine tuning member and a first and a second planes can automatically reset by the elastic force of a first elastic element. In addition, the spacing between the fine tuning member and the first and the second planes can be adjusted in micro quantity by rotating the fine tuning member, so the improved wrench can be suitable for various different sizes of screw bolts.

Description

The spanner of improvement

The utility model is relevant a kind of hand-operated tools, refer to especially a kind of easy to adjust and quick, and the spanner of improvement that can strong fix.

See also Fig. 9, commonly use spanner and have a lever 8 and a slide 9, one side of this lever 8 is provided with most teeth 81, but its end has the folder portion 82 of a grip bolt 7, one side of this slide 9 is provided with one 91, this 91 pivot joint, one driving lever 92 that replaced by shell fragment 93, these driving lever 92 1 ends have tooth 81 engagements of most teeth 921 and this lever 8.

During use, the tooth 81 that user's hand must be pushed tooth 921 that driving lever 92 makes driving lever 92 and lever 8 breaks away from, could forward and backward mobile lever 8 with the distance of 94 of the lean against part that change folder portion 82 and slide 9.And in the process of mobile lever 8, must keep the tooth 921 of driving lever 92 could constantly pass lever 8 with the state that the tooth 81 of lever 8 separates fully always.And when pushing driving lever 92, promote to have the lever 8 of suitable weight, the wayward only distance of displacement one tooth of lever 8 that makes of the strength of its promotion, and be difficult to the distance that trace is adjusted a tooth, 7 on the bolt that causes folder portion 82 and pulled has a spacing, and can't lose the effect of spanner really with bolt 7 clamping switchings.

Because driving lever 92 is to be hubbed on the slide 9 by axle 91, and replaced by shell fragment 93 and with lever 8 on tooth 81 engagement, need push driving lever 92 during use its tooth 921 is separated fully with the tooth 81 of lever 8, can promote the distance that lever 8 is adjusted this folder portion 82 and lean against part 94.If fully driving lever 92 is not pressed into the end, promptly move this lever 8, because still having near this part tooth 921 of 91, this driving lever 92 do not break away from the tooth 81 of lever 8, and be easy to wear and tear, if things go on like this, this part tooth 921 can be worn away, and only is easy to generate slip by tooth 81 engagements of remaining tooth 921 and lever 8, and influences the locating effect of driving lever 92.

In addition, this kind spanner is to promote lever 8 adjusting the distance of this folder portion 82 and lean against part 94, but when being used for the bolt 7 of different sizes, the multiple distance that it only can this tooth 81 of displacement, and can't cooperate different bolts 7 sizes fully.Bigger as if tooth 81 is made, its engagement strength is bigger, but adjustable scope diminishes; Otherwise the strength of the less engagement of tooth 81 sizes is not enough again, is easy to generate slip.

Main purpose of the present utility model is, for the spanner that above-mentioned problem that spanner exists provides a kind of improvement is commonly used in solution, because it is quite light and handy for the slide block of adjusting trimming piece and this first and second interplanar distance, and it can automatically reset by the elastic force of first flexible member, and reaches easy to adjust and effect fast.

A time purpose of the present utility model is, a kind of spanner of improvement is provided, by the tooth of slide block can be simultaneously with the tooth engagement of gear block or separate, and can avoid the wearing and tearing of this gear block part tooth, and make between this gear block and slide block enough contacting and engagement force arranged.

A purpose more of the present utility model is, a kind of spanner of improvement is provided, and can adjust trimming piece and this first and second interplanar spacing by trace by rotary fine adjustment spare.

The purpose of this utility model is realized by following technical scheme.

A kind of spanner of improvement, comprise: body, slide block, casting die, described body is established more than one cushion block by a top board and base plate folder and is formed, this body front end has a holding section, this holding section has one first and one second plane at least, this first and second interplanar accompanies an angle and forms an engaging space, and this body is provided with a microscler chute that communicates with the engaging space in the side with respect to first, second plane; Described slide block is located in the chute of this body, and a side of this slide block is provided with most teeth; Described casting die is installed with a gear block, and the face that this gear block is relative with this slide block is provided with most teeth; It is characterized in that: described cushion block inside has the space that is installed with each member, one side of this body chute is provided with more than one elongated slot, and its bottom is provided with a hook portion, the rear end of this slide block is provided with a hook portion, be provided with an extension spring between the hook portion of this chute and the hook portion of this slide block, this slip front is provided with a screw rod, revolve lock on this screw rod one trimming piece is arranged, this trimming piece is in the engaging space, place, position, and this slide block is installed with the push button of this body of protrusion, and this casting die sets firmly this gear block with the elongated slot that more than one fixture passes this body, and the tooth of this gear block can be simultaneously with the tooth engagement of this slide block or separate, in addition, this casting die forms a press section in the opposite side of this slide block, be provided with most flexible members between this press section and this body, this flexible member makes the tooth engagement of normal maintenance of the tooth of this casting die and slide block.

The purpose of this utility model can also further realize by following technical measures.

The spanner of aforesaid improvement, cushion block wherein can be formed by stacking by the multi-disc flat board.

The spanner of aforesaid improvement, body back segment wherein has a hollow bulb, and a side of this hollow bulb is articulated with a side cover, and this side cover is provided with the groove that majority can supply tool heads to plug.
