Abstract
The utility model discloses a handsaw pull rod, including ladder pin, spring leaf, pull rod, wherein the assembly of ladder pin is in the planar shoulder hole of pull rod, and the thin end of ladder pin is equipped with the dop, uses the material to make the spring leaf of question mark shape as the steel sheet of spring steel, with the screw fixation on the pull rod plane, just constituted a handsaw pull rod. The utility model discloses simple structure, convenient to use have solved saw blade mounting hole position and have had the not enough of clearance with the pull rod plane.
Description
Technical field
The utility model belongs to manual tool technical field, specifically a kind of handsaw pull bar.
Background technology
Handsaw is the common instrument that pincers worker uses in sawing operation.Respectively there are steady brace and active pull rod in the rear and front end of saw bow, and two pull bars are all equipped with pin, utilizes saw blade two ends installing hole to coordinate with pin and installs saw blade, regulates active pull rod to make saw blade tensioning, can carry out sawing operation.Pincers worker handsaw must ensure that saw blade is tension in operation, pulling force on saw blade acts on the pin at two ends, operator is when using handsaw to carry out sawing work, due to saw blade unbalance stress in push-and-pull process, often make the plane on the side at saw blade two ends and pull bar not be close together, but leave certain gap, this gap causes when sawing, saw blade swings back and forth in the left and right sides in fortune saw direction, makes saw kerf depart from drawn line, is difficult to levelling.
Utility model content
The utility model overcomes the deficiency of background technology, provides a kind of handsaw pull bar that saw blade and pull bar plane can be close together.
The design that the utility model adopts is: the spring leaf being made into question mark shape with the sheet metal that material is spring steel, be screwed in pull bar plane, form a pull bar entirety, spring leaf is arranged the elliptical aperture of larger than pin one week, ladder pin movable on pull bar is arranged on to penetrate, install by the ladder pin on pull bar and strain saw blade, the handsaw pull bar that so just formation one is novel.
The utility model structure is simple, be easy to processing and fabricating, easy to use, be applicable to all kinds of handsaw having identical mounting means.
Accompanying drawing explanation
Accompanying drawing 1 is the package assembly schematic diagram that the utility model band is analysed and observe;
Accompanying drawing 2 is top views of the utility model accompanying drawing 1;
Accompanying drawing 3 is left sectional views of the utility model accompanying drawing 1.
1. ladder pin, 2. spring leaf, 3. fixed screw, 4. pull bar, 5. dop, 6. saw blades in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of handsaw pull bar, comprise ladder pin 1, spring leaf 2, pull bar 4, wherein ladder pin 1 is assemblied in the shoulder hole of pull bar 4 plane, and the taper end of ladder pin 1 is equipped with dop 5, adopts riveted joint or welding to make ladder pin 1 connect in aggregates with dop 5, spring leaf 2 is fixed in the plane of pull bar 4 by screw 3, the handsaw pull bar that just formation one is novel.
The utility model pull bar shoulder hole will coordinate with ladder pin size, excessive gap can not be had to make ladder pin again, and in shoulder hole, activity is freely, ladder pin butt end plane and pull bar plane will remain on same plane or lower slightly, when dop contacts with pull bar, the butt end of ladder pin still matches with the butt end in pull bar shoulder hole, the tail end of spring leaf contacts with the vertical plane of pull bar, prevents spring leaf from being swung by screw single-point fixing appearance.When saw blade is installed, saw blade 6 is inserted by the contact site of spring leaf and pull bar plane, elliptical aperture in the middle of spring leaf is observed, be beneficial to ladder pin and penetrate saw blade installing hole and elliptical aperture, spring leaf acts on one, saw blade installing hole position pressure all the time, makes saw blade and pull bar plane close contact, prevents saw blade from swinging on fortune saw direction, thus ensure that saw kerf carries out sawing along line, make operator more easily grasp the operation of sawing.
The above embodiment is only further illustrate of the present utility model, not does other forms of restriction to the utility model, and every the utility model that utilizes makes various corresponding change and distortion, all should comprise in scope of patent protection of the present utility model.
