Description
Technical field
The utility model relates to the Hand saw technical field with Straight blade.
Background technology
Arm saw is a kind of universal tool, in the cutting of repair of machine, steel, makes by hand, the field purposes such as timber processing, decorations is a lot.In prior art, the saw blade of Arm saw is installed and must be connected with saw bow with members such as butterfly bolt, box hook, pins, and saw blade fitting operation is loaded down with trivial details, and saw blade dismounting is not quick; In long-time use procedure, make saw bow distortion because the member stress such as butterfly bolt, box hook, pin are uneven, often occur saw blade phenomenon of rupture; Because using wearing and tearing to affect production efficiency in operating process.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Arm saw, has simple in structure, conveniently feature of handling saw blade.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of Arm saw, comprises saw bow and saw blade; Described saw bow is that a round steel is made by bending, described saw bow both ends are provided with axial notch, described saw blade is connected between saw bow both ends and embeds in axial notch, inserts respectively pin in the through hole at saw blade two ends, and described pin lays respectively at the outside, both ends of saw bow.
The further improvement that the utility model is done is: described saw bow comprises forearm, horizontal arm, handle outer side edges, handle inner side edge and upright arm; Angle between described forearm and saw blade is acute angle, and the angle between forearm and horizontal arm and between horizontal arm and handle outer side edges is obtuse angle, and the angle between handle inner side edge and upright arm is acute angle, and the angle between upright arm and saw blade is right angle.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, is adapted at job location and gathers materials on the spot, and easily makes, and handling saw blade is quick, easy to operate, can raise labour efficiency.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model:
As shown in the figure: 1 pin, 2 forearms, 3 horizontal arms, 4 handle outer side edges, 5 handle inner side edges, 6 upright arms, 7 saw blades.
Detailed description of the invention
Contrast Fig. 1 uses step to be described further to operation of the present utility model:
Embodiment 1: a kind of Arm saw, comprises saw bow and saw blade 7; Described saw bow is that a round steel is made by bending, described saw bow both ends are provided with axial notch, described saw blade 7 is connected between saw bow both ends and embeds in axial notch, inserts respectively pin 1 in the through hole at saw blade 7 two ends, and described pin 1 lays respectively at the outside, both ends of saw bow.The using method of the present embodiment: this Arm saw is adapted at job location and gathers materials on the spot, easily makes.Can select the round steel of diameter 12mm, the length 12cm of forearm 2, the length 26cm of horizontal arm 3,136 ° of the angles between forearm 2 and horizontal arm 3.Forearm 2 lower ends and upright arm 6 lower ends must keep same level, after saw blade 7 is installed, and 90 ° of the angles between upright arm 6 and saw blade 7,44 ° of the angles between forearm 2 and saw blade 7.This saw bow front portion is triangle, prevents that saw blade 7 is loosening.When saw blade 7 is installed, saw blade 7 is embedded in the axial notch at saw bow both ends, in the through hole of saw blade one end, insert pin 1, push at saw bow opposite side a little, insert second pin 1, restore to the original state because the strain of round steel makes saw bow, saw blade 7 is clamped on saw bow.
Embodiment 2: a kind of Arm saw, comprises saw bow and saw blade 7; Described saw bow is that a round steel is made by bending, described saw bow both ends are provided with axial notch, described saw blade 7 is connected between saw bow both ends and embeds in axial notch, inserts respectively pin 1 in the through hole at saw blade 7 two ends, and described pin 1 lays respectively at the outside, both ends of saw bow.Described saw bow comprises forearm 2, horizontal arm 3, handle outer side edges 4, handle inner side edge 5 and upright arm 6; Angle between described forearm 2 and saw blade 7 is acute angle, angle between forearm 2 and horizontal arm 3 and between horizontal arm 3 and handle outer side edges 4 is obtuse angle, angle between handle inner side edge 5 and upright arm 6 is acute angle, and the angle between upright arm 6 and saw blade 7 is right angle.The using method of the present embodiment is identical with embodiment 1.
