Abstract
The utility model relates to a high efficient spanner of the hand tool. The utility model is composed of a handle with a fixed clip tip, an adjustable spanner composed of a hand wheel and a hand wheel shaft, a fixing guide rail arranged on the adjustable spanner, a toothed belt of the fixing guide rail, a spring, a pawl, a tongue piece on the sliding clip tip, which are connected together, Because the sliding clip tip can quickly slide in the fixing guide rail, the locking function is completed by using the work piece pressure, and thus, the utility model is used for adjusting the size of the spanner opening. Compared with the present adjustable spanner, the high efficient spanner can improve the work efficiency more than 3 times.
Description
The utility model relates to a kind of efficient adjustable wrench of hand-operated tools.
Existing adjustable wrench is the distance of adjusting slide card point and fixing card point by the operation handwheel fully, to satisfy the requirement of different size connector.When the size specification of connector differs far away, just exist slow, the inefficient deficiency of speed with the handwheel adjustment.
The purpose of this utility model is to provide a kind of no matter the connector specification differs much, can both finish the efficient adjustable wrench that loosens, tighten function quickly and efficiently.
The utility model is achieved in that on the common adjustable wrench that handle, handwheel and the hand wheel shaft of the fixing card point by band are formed, and fixed guide is housed, and spring, ratchet and tongue piece on the cingulum on the fixed guide and the card point that slides are formed by connecting.Owing to slide the card point can be in fixed guide fast moving, and can utilize the pressure of workpiece to finish to lock function, so just can reach purpose rapidly and efficiently by tongue piece, spring and cingulum.
Further operation principle of the present utility model is described in further detail below in conjunction with drawings and Examples.
Shown in the drawings is that the utility model is at the improved structural representation of active card nose part.
With reference to accompanying drawing, on the handle of the fixing card point of band, the spiral handwheel is housed by hand wheel shaft.Fixed guide 1 is contained on the spiral handwheel by the helical tooth of its underpart.Be contained in tongue piece 5, spring 4 and ratchet 3 on the card point 6 that slides, be contained on the fixed guide 1 by the cingulum on the fixed guide 12.The card point 6 that slides is slided to the terminal propelling workpiece of clamped condition and the tongue piece made from spring steel with Work-sheet pressing 5, make the card point 6 that slides by ratchet 3 stuck can not slips, adjusting handwheel makes whole work-piece clamped, pull handle, workpiece is followed the spanner rotation, when stopping to pull handle, only needs pumpback one distance to decontrol tongue piece 5, ratchet 3 is because spring 4 power effects just can be unclamped automatically, and sharp 6 parts of card of at this moment sliding just can be free to slide.Card point 6 unclamps and (moves if work piece drag can not promote slip card point 6 if counter-rotation handle (noting not firmly top tight workpiece) slides owing to work piece drag will make, then can directly stir with hand) sharp 6 parts of card of sliding move enough apart from the time, pull the handle workpiece and no longer follow rotation, when at the no good again hand of suitable angle, as long as the power of spring 4 is selected suitably (greater than the gravity of active card point 6 parts), the card point 6 that slides just slides earlier and clamps, and then stuck with ratchet 3, at this moment can work on again.
Another kind of working method is after rotating once spanner to be extracted out, on suitable angle, pushing again slide card point 6 just automatically clamping work pieces worked on.
Use high-efficiency clyburn spanner described in the utility model, compare with existing adjustable wrench, in the situation that often needs adjustment wrench opening size, can increase work efficiency more than 3 times.
Claims (2)
1, a kind of efficient adjustable wrench is made up of handle, handwheel, the hand wheel shaft of the fixing card point of band, it is characterized in that being contained in the spring 4, ratchet 3 and the tongue piece 5 that slide on the card sharp 6 and is connected with cingulum 2 on being contained in fixed guide 1.
2, adjustable wrench as claimed in claim 1 is characterized in that tongue piece 5 made by spring steel.
