Abstract
Disclosed is a hand saw, which is composed of a bow saw frame (1) and a saw blade (9). The utility model is characterized in that the rear part of the bow saw frame (1) is provided with a groove-shaped cavity (12) and a lever mechanism of the tensioning saw blade (9) is arranged in the cavity; the lever mechanism is composed of a plate (2), clamping plates (3) and a push-pull rod (4); the two clamping plates (3) are arranged on one side of the plate (2) and one side of the push-pull rod (4) to tightly clamp and fix the plate (2) and the push-pull rod (4) between the two clamping plates; the plate (2) utilizes a shaft (5) of the bow saw frame (1) as a rotary shaft; the push-pull rod (4) utilizes a shaft (6) of the bow saw frame (1) as a rotary shaft; the push-pull rod (4) is a flat rod which is provided with a lower kick pleat (43); a clamp of the lower kick pleat (43) is arranged on a tensioning movable shaft (8) of the saw blade (9).
Description
The utility model relates to a kind of Hand saw.
Present Hand saw adorning the tensioning state that saw blade will remove to regulate saw blade often by hand, uses inconvenience.
Task of the present utility model is to propose a kind of Hand saw that can regulate the saw blade tensioning state automatically
The technical solution of the utility model is: Hand saw is made up of arc saw frame, saw blade.There is slotted cavities at the rear portion of arc saw frame, the leverage that the tensioning saw blade is arranged in the cavity, leverage by the plate, clamping plate, the pull bar that play leverage constitute, second splint grip at plate, pull bar two sides, with plate, pull bar be fixed between the second splint, plate is turning cylinder with the axle (5) of arc saw frame, pull bar is that turning cylinder, pull bar are the flat rod that following jag is arranged with the axle (6) of arc saw frame, and following jag fork is on the movable axis of regulating the saw blade tensioning
Because the effect of leverage, when plate rotates, the fork of pull bar bottom, push away, draw movable axis correctly to regulate the rate of tension of saw blade automatically, finish the invention task.
Fig. 1 is embodiment of the present utility model.
Fig. 2 is the embodiment of plate.
Fig. 3 is the embodiment of clamping plate.
Fig. 4 is the embodiment of pull bar.
Be described in detail the utility model below in conjunction with accompanying drawing
The utility model Hand saw, form by arc saw frame (1) saw blade, there is the leverage that tensioning saw blade (9) are arranged in slotted cavities (12) cavity at the rear portion of arc saw frame (1), leverage has had the plate (2) of leverage, clamping plate (3) pull bars (4) constitute, two clamping plate 3) in plate (2), pull bar (4) two side faces grips plate (2) pull bar (3) and is fixed between the second splint, plate (2) is a turning cylinder with the axle (6) of arc saw frame (1), pull bar (4) is the flat rod that following jag (43) is arranged, and following jag (43) fork is on the movable axis (8) of regulating saw blade (9) tensioning.
Plate (2) porose (21) has last hole (42), following hole (41), clamping plate (3) to be spill with hole (22), pull bar (4), the fixed structure that grips of porose (31) (32), second splint (3) and plate (2), pull bar (4) is: hole (21), hole (31), fixed by rivet (231) rivet, hole (32), hole (42) are fixed by rivet (342) rivet.
Hole (22) on the plate (2) is enclosed within on the axle (5), and the following hole (41) of pull bar (4) is enclosed within on the axle (6).
Plate (2) has handle (23) to be used to make plate (2) to rotate around axle (5), can have the arc saw frame of bolt (7) that handle (11) is arranged in the movable axis (8).
Because leverage, when handle (23) makes plate (2) when the state I turns to the state II, the fork (43) on the pull bar (4) presses movable axis (8) unclamps saw blade (9).
Operating grip makes when returning to form I, and fork (43) is pulled out activity, and axle (8) tensioning saw blade (9) (Fig. 1).
The utility model Hand saw, easy to use, function-stable, simple in structure, cost is low, practicality good.
