Abstract

The utility model relates to a steel saw with a movable handle, which belongs to hand tools. The steel saw is composed of a saw handle, a saw bow and a locker, wherein the saw handle can be adjusted on the saw bow at multiple angles, and the locker is composed of the saw handle, a disc-shaped tooth structure on the saw bow, and a screw stud and a butterfly nut on the saw bow. The steel saw has the characteristics of simple structure, comfortableness and labor saving in use, and is suitable for operation at different angles.

Description

Live hacksaw

Technical field

The utility model relates to a kind of common tool one hacksaw.Be a kind ofly can artificially control the hacksaw handle angle according to user's use needs, make things convenient for living hacksaw of execute-in-place.Can make more easy and convenient the operating of operator.

Technical background

At present, the handle of known hacksaw all is fixed angle, and when big, the user can feel when work not smoothly and fatiguability in operation height and the personal discrepancy in elevation.

At above-mentioned deficiency, I have developed a kind of novel living hacksaw, and the structure of common hacksaw is improved, and make the adjustable operating angle of handle.The angle that makes the operator can regulate the hacksaw handle according to the working condition of reality easily like this when operation is to reach the most comfortable labour-saving work angle.Solve former fixed handle, operated hard and inconvenient problem in many cases.

Summary of the invention

Existing hacksaw handle is fixed in order to overcome, the deficiency of non-adjustable saw handle angle, the utility model provides a kind of and lives hacksaw, and this hacksaw can not only be worked as common hacksaw, and can be according to the needs of practical operation, the angle of manual adjustment handle makes operation more comfortable laborsaving.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of living hacksaw, formed by saw handle, saw bow, locker, and it is characterized in that: saw handle and saw bow are the whole structure of multistage adjustable angle.Locker is made up of Fig. 7, part shown in Figure 8 and wing nut, is angle adjustment and locking and fixing device.Detent projection on Fig. 7, Fig. 8 part (this bossing can adopt various ways, is advisable so that adjust angle) be used for adjusting and fastening saw handle and saw bow between angle.When needs are adjusted the saw handle angle, only need unscrew wing nut, can adjust the angle between saw handle and the saw bow, adjusts suitable after need wing nut is tightened.

The beneficial effects of the utility model are, can be artificial regulate angle between saw handle and the saw bow according to action need.Easy to operate, can arbitrarily change its angle, more comfortable laborsaving during use.

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified.(core of the present utility model is the adjustable angle between saw handle and the saw bow.Its outward appearance can arbitrarily design, and understands for convenience here, and it is simpler and cruder that outward appearance is drawn.Core of the present utility model is the adjustable angle that is between saw handle and the saw bow.)

The specific embodiment

The utility model is to carry out improved on common hacksaw basis, Fig. 1 is initial equilibrium state figure of the present utility model, look basically identical with common hacksaw, if when operation, need regulate the angle between saw handle and the saw bow, only need its wing nut is unscrewed, the dentation device on Fig. 7, Fig. 8 part is separated, regulate angle to the suitable angle between saw handle and the saw bow then, tighten wing nut, the dentation device locking on Fig. 7, Fig. 8 part is got final product.

Claims

1. a work is made of hacksaw saw handle, saw bow, locker, it is characterized in that: saw handle and saw bow are the whole structure of multistage adjustable angle.

2. according to the described hacksaw of claim 1, it is characterized in that: the disc tooth-like part of anything on saw bow rear portion and saw handle one end and wing nut constitute a locker.

3. according to the described hacksaw of claim 1, it is characterized in that: locker can be the plane formula locker, tooth on it can be triangle, rectangle, trapezoidal, arc, outer tooth ring shape locker in also can adopting, pin-and-hole formula locker, and the friction lock device, with adjustment saw handle angle, and prevent from rocking.
