Background

The hacksaw is a tool frequently used in construction, but most of saw bows purchased in the current market are inclined, and the saw blade is easy to break due to insufficient tension force. And in the construction site, a plurality of workers are often required to handle one hacksaw to accelerate the construction progress, and the phenomenon of shortage of the number of the hacksaws usually occurs, so that the workers cannot handle one hacksaw or only use simple saw blades, and the construction quality and progress are seriously influenced. Meanwhile, waste materials such as round steel and the like can be seen everywhere in a construction site, such as the waste materials of the lightning rod for electrical construction and the like. Therefore, the steel saw which can be manufactured by using waste materials on site and has the advantages of simplicity and good practicability is urgently needed.

Disclosure of Invention

The utility model discloses the problem to the aforesaid that awaits the solution urgently invents a can the on-the-spot simple and easy hacksaw who makes of abandonment materials such as electric construction lightning rod on the spot, because electric construction lightning rod abandonment material is the zinc-plated material, makes simple and easy instrument convenient durable, and difficult corruption.

The utility model discloses a following mode realizes:

the utility model discloses a simple and easy hacksaw is including bow (1), saw blade (2), anterior pin (3), rear portion pin (4), the bow is bent, simple welding is made by a zinc-plated round steel, and the bow includes that the arc is anterior, the front portion is shaken hands, straight middle part, arc rear portion is shaken hands, the arc is anterior 145 jiaos, anterior shake hands with straight middle part is welded connection, the saw is held to arc rear portion hand of holding laminating hand, and the yardstick is more reasonable, the both ends of bow respectively set up a vertical groove of putting the saw blade along the axis of round steel, and vertical groove width is 1.0mm, and two sides of vertical groove position placed in the middle respectively transversely set up anterior cotter hole (5) and rear portion cotter hole (6) of a fixed saw blade, and the saw blade is fixed through the pin at both ends, the saw blade is 120mm with the interval at the straight middle part of bow. The model of the round steel is phi 12. The round steel is galvanized round steel or copper-plated round steel. The connection of the front grip to the straight middle of the saw bow may also be a rivet or screw connection. The diameter of the fixing hole of the hacksaw is 3 mm.

The utility model has the advantages that:

(1) the structure is simple, and the comfort level of the grip is high;

(2) the design of the front handle enables the operation of two hands to be possible, and meanwhile, the downward pressure of the front handle improves the working efficiency of sawing hard steel and solid steel bars;

(3) the waste round steel is used for on-site manufacture, waste utilization and environmental protection are achieved.

The saw comprises a saw bow 1, a saw blade 2, a front pin 3, a rear pin 4, a front pin hole 5 and a rear pin hole 6.

Detailed Description

The utility model discloses a simple and easy hacksaw is including bow (1), saw blade (2), anterior pin (3), rear portion pin (4), the bow is bent, simple welding is made by a galvanized round steel, and the bow includes that the arc is anterior, the front portion is shaken hands, straight middle part, arc rear portion are shaken hands, the arc is anterior is 145 jiaos, increases the tension of bow, and anterior shaking hands increases the holding force when using, and the arc is held hand laminating hand and is held the saw yardstick more rationally, wholly plays certain tension to the bow during use. The front handle and the straight middle part are in welded connection, two ends of the saw bow are respectively provided with a longitudinal groove for placing a saw blade along the axis of the round steel, the width of the longitudinal groove is 1.0mm, two side surfaces of the longitudinal groove are respectively transversely provided with a front pin hole (5) and a rear pin hole (6) for fixing the saw blade, and the distance between the saw blade and the straight middle part of the saw bow is 120 mm. The model of the round steel is phi 12. The round steel is galvanized round steel or copper-plated round steel. The connection of the front grip to the straight middle of the saw bow may also be a rivet or screw connection. The diameter of the fixing hole of the hacksaw is 3 mm. The saw blade passes through anterior pin (3) and rear portion pin (4) are fixed in the pin hole, the degree of depth of two longitudinal grooves be 10 mm.

When the steel saw blade handle is used, the front end of the steel saw blade (2) is placed into the front longitudinal groove and then fixed through the front pin (3), the front end of the saw bow is pushed to press the arc-shaped rear handle with force, and the rear end of the steel saw blade (2) is placed into the rear longitudinal groove and fixed through the rear pin (4). The simple steel saw can be normally used.
