Abstract

The utility model relates to a hand tool with a foldable pull rod. The hand tool can finish shearing, tonging, clamping and calipering work, etc., under special conditions, and can be folded. The hand tool is convenient to be carried. The utility model is composed of a tool part (figure 2), a driving pull rod (figure 2) and a manual part (figure 4), and the three parts are mutually connected.

Description

Hand tool with foldable pull-rod

The utility model is a kind of foldable pull rod-type hand tools series.

Hand tools such as at present people use cuts, clamp, folder, slide calliper rule are all because of can only using in the human arm length range, and can not use in that some specific conditions are next.Such as, object in crack, when staff can't enter crack, then can't finish with general tool, at this moment people often use relatively large long-armed instrument.And large-scale instrument inconvenience is carried.The utility model has overcome the weakness of above instrument.

The utility model utilizes lever and gear drive principle to make.

The utility model is made of Fig. 2, tools section, Fig. 3, shackle rod, Fig. 4, manual part, and three parts interconnect, and the hand tools that formation can fold makes this instrument be fit to specific condition and uses down, and is easy to carry.

After the utility model is achieved in that manual part is stressed, by gear and multiple tooth drive link active force is passed to shackle rod after, pass to tools section by shackle rod, instrument is worked.

Fig. 1, be a kind of concrete structure longitudinal sectional drawing of the present utility model.

Fig. 2,3,4, be exploded view.

Fig. 1, mark 1, be instrument, instrument can be and cuts, clamps, folder, slide calliper rule＜Fig. 2-1〉2, be to drive instrument by drive link by drive link, there is a garden shape sheet drive link top, as the spring pressure sheet.3, be spring, work making instrument recover the open configuration effect.4, for pull bar, pull bar are more piece, tubular, the spiral shell button of fixation having been arranged between joint and the joint or blocked can be overlapping between button＜Fig. 3-2〉joint and the joint.5, be shackle rod, shackle rod is to link to each other with hook＜Fig. 3-3〉between more piece, triangle＜Fig. 3-1〉save and save, every joint up-thin-low-thick＜Fig. 3-4 〉, can be overlapping between shackle rod joint and the joint, shackle rod is near a joint of manual part, should save weak point than one of the close manually part of pull bar, and link to each other with the drive link that is connected manual part.6, be spring, work to support that the power rod makes its attitude that resiles after losing pressure.7, be gear, 10, for multiple tooth drive link, both interact, in order to the tractive instrument.8, be pulley, play fixing multiple tooth drive link position.9, be spring.11, be Baltimore groove, in order to hold drive link.12, be tubular instrument cap,, can with the instrument cap on instrument, be easy to carry in instrument time spent not.13, the power rod, be the power source of this instrument, staff makes instrument stressed by it.
