Abstract

A novel saw bow belongs to metal products, and is provided with an adjusting lever used for assembling or disassembling a saw blade, and formed by an F-shaped saw bow frame and the L-shaped adjusting lever. The F-shaped saw bow frame includes a front bow bar, a waist bow bar, a rear bow bar and a handle bar, wherein the a saw blade front suspension column laterally perpendicular is arranged at the front end of the front bow bar, both of the front bow bar and the rear bow bar are perpendicular to the waist bow bar, distance between the front bow bar and the rear blow bar is equal to distance between two hole centers of two ends of the saw blade, the handle bar at the rear end and the waist bow bar form an included angle of 120 degrees, the handle bar is embedded into the inner face of a half-handle bar on the outer side, the front end of the adjusting lever is a front perpendicular bar, the front end of the front suspension bar is provided with a saw blade rear suspension column, the adjusting lever is overlapped on the rear bow bar and the rear portion of a saw bow frame and has the structure the same as the rear bow bar and the rear portion of the saw bow frame, a hole at the front end of the rear bow bar corresponds to a hole on the front perpendicular bar, and the front end of the rear bow bar and the front perpendicular bar are tight riveted via a rivet, two half-handle bars are combined into a single handle rotatable under force and are separable, and the saw blade is suspended to the front suspension column and the rear suspension column. The novel saw bow has simple structure and convenient use and saw blade replacement.

Description

Novel saw bow

One, technical field

Novel saw bow belongs to the hardware product, relates to the hacksaw saw bow, particularly the structure of getting the saw bow of saw blade with lever method dress.

Two, background technology

Hacksaw saw bow commonly used is that the apparatus wing is regulated the fastening hacksaw blade that tangles of nut, and dress is got equal inconvenience.

Three, summary of the invention

The utility model is a kind of novel hacksaw saw bow of getting with the dress of the convenient, fast adjusting hacksaw blade of adjustment (adjusting) lever of invention.

1, technical scheme

Novel saw bow is made up of F shape saw bow frame and the shape adjustment (adjusting) lever two large divisions of factory, the saw bow frame is by the anterior arch bar, the arcus pelvicus bar, the cantle bar, the handle bar is formed, front and back bow bar is all perpendicular to the arcus pelvicus bar, spacing is identical with saw blade two stomidium hearts distance, terminal handle bar and arcus pelvicus bar are 120 ° of angles, be embedded in the wooden of the outside or plastics matter half handle inner face, anterior arch bar front end, the preceding hanging column of saw blade that the outer center of one side has side to hang down, the adjustment (adjusting) lever front portion is preceding vertical bar, be overlapped in the cantle bar, its rear structure is corresponding identical with F shape saw bow frame rear structure, and the preceding vertical bar length and the anterior arch bar of its front end are isometric, hanging column behind the saw blade that hangs down outside having on it, cantle bar front end has nail hole, a fourth of the twelve Earthly Branches, the preceding bar that hangs down is overlapped in its corresponding position of cantle bar, and nail hole, an identical fourth of the twelve Earthly Branches is also arranged, and follows closely with both tight fourths of the twelve Earthly Branches together with the fourth of the twelve Earthly Branches, two and half handles are combined into a handle, adjustment (adjusting) lever are rotated and two and half handles separate.

2, beneficial effect

Simple in structure, it is convenient and swift that dress changes saw blade.

Four, description of drawings

Fig. 1 is novel saw bow structure diagram.

Among Fig. 1: hanging column 10 fourths of the twelve Earthly Branches nail 11 behind bar 9 saw blades that hang down before hanging column 7 adjustment (adjusting) levers 8 before saw bow frame 1 anterior arch bar 2 cantle bars 3 arcus pelvicus bars 4 handle bars 5 half handles 6 saw blades

Five, the specific embodiment:

With reference to accompanying drawing 1 usefulness cross section 4 * 18 millimeters vertical making of high-quality band steel material, 8 centimetres of 2 length of anterior arch bar foremost of F shape saw bow frame 1,3.8 millimeters of the vertical φ of its front end central side, hanging column 7 before the high 15 millimeters saw blade, 34 centimetres of arcus pelvicus bar 4 length, 6 centimetres of cantle bar 3 length, there are 5 millimeters circular holes of φ in front end central authorities, anterior arch bar 2 and cantle bar 3 are all perpendicular to arcus pelvicus bar 4,30 centimetres of centre-to-centre spacing (hacksaw blade of joining 30 centimetres of saw blade hole centre-to-centre spacing), 11 centimetres of handle bar 5 length, be 120 ° of angles with arcus pelvicus bar 4, there is one 30 millimeters * 10 millimeters * 10 centimetres half handle 6 in its outside, and handle bar 4 vertical build-ins are gone into half handle, 5 inner faces, 8 centimetres of preceding vertical bar 9 length of adjustment (adjusting) lever 8 front ends, front end has 5 millimeters holes of φ with the corresponding position, hole that overlaps on the cantle bar 3,3.8 millimeters of the vertical φ of preceding vertical bar 9 front end center line upsides, hanging column 10 behind the high 10 millimeters saw blade, and the remainder of adjustment (adjusting) lever 8 is overlapping and corresponding identical with saw bow frame 1 rear portion, live cantle bar 3 and adjustment (adjusting) lever 8 with the nail 11 tight fourths of the twelve Earthly Branches, 5 millimeters fourths of the twelve Earthly Branches of φ, but firmly rotatable getting final product.
