Description

Saw capable of reversing
Technical field
The utility model belongs to the sawing instrument, a kind of specifically saw capable of reversing.
Background technology
Existing saw, position relation between its saw bow and the handle is unadjustable, as Chinese utility model patent ZL03225125.4 number " installing and removing the saw of saw blade fast " and ZL200620088201.2 " multifunctional assembled hacksaw ", therefore, after installing saw blade, distance between saw blade and the saw bow is fixed, and big young pathbreaker that should distance influence saw can carry out sawing and saw to great workpiece can operation in great working space, be in particular in following two aspects:
1, when the distance between saw blade and the saw bow is big, it can once come bigger workpiece sawing, but the narrow and small operation occasion in some spaces owing to this distance causes not having enough positions to hold saw greatly and for the saw activity, thereby is difficult to smoothly the workpiece of this occasion is carried out sawing;
Otherwise 2, the distance between saw blade and saw bow hour, it is can be in some narrow spaces movable smoothly and implement the sawing operation, but be difficult to owing to this distance is less once will be bigger the workpiece sawing come.
So existing saw is difficult to take into account simultaneously the bigger workpiece of sawing and is applicable to narrow and small working space.
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the defective that existing saw is difficult to take into account the bigger workpiece of sawing simultaneously and is applicable to narrow and small working space, a kind of saw capable of reversing is provided, so that to the saw bow commutation, satisfy different user demands as required.For this reason, the utility model is by the following technical solutions:
Saw capable of reversing is characterized in that comprising:
Saw bow, it is bending, and its two ends are provided with mounting structure respectively;
Handle, it is provided with a saw bow installation portion and a pulling assembly, and described pulling assembly has the saw blade installation portion;
Head is installed, and it is provided with saw bow installation portion and saw blade installation portion;
Saw blade, its two ends are installed in the saw blade installation portion of described pulling assembly and install on the saw blade installation portion of head;
Capable of reversing being installed together of saw bow installation portion on the mounting structure at described saw bow two ends and the saw bow installation portion on the handle and the installation head.
This saw can be installed in forniciform saw bow commutation between handle and the installation head when work as required, thereby changes the distance between saw bow and the saw blade, is applicable to different demands.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature, so that when implementing, select for use as required:
The mounting structure at described saw bow two ends is plug, jack or is respectively plug and jack; Saw bow installation portion on the described handle and the saw bow installation portion of installing on the head are to realize jack, the plug of pegging graft or be respectively jack and plug with the mounting structure at described saw bow two ends.This structure is convenient to handle, saw bow, installation head and saw blade fits together and saw bow is commutated.
Be connected with hold-down screw between the saw bow installation portion on the mounting structure at described saw bow two ends and the saw bow installation portion on the handle and the installation head.So that saw bow is implemented operation with handle with installing that head is connected reliably.
Described saw bow two ends are provided with the plane of pair of parallel, described two mounting structures respectively from its plane at one end stretch out; Described handle with head is installed on be respectively arranged with and this matching surface corresponding parallel plane.Such structure can make the contact site of saw bow and handle and installation head keep neat, when guaranteeing that relation is installed in saw bow and handle and the position that head is installed, also makes it fit together and has neat outward appearance.
The mounting structure at described saw bow two ends is positioned on the same straight line vertical with the plane at described saw bow two ends.Such structure makes saw bow not have directionality, therefore, in when assembling, can any end be connected with handle and installation, makes simple and convenient assembly, easy to operate.Further, the two ends of described saw bow are symmetrical arranged.Described saw bow is circular-arc.
The cross section of described jack, plug is a rectangle.Such structure can be avoided saw bow and handle and change in location between the head is installed, thereby can prevent that in use saw blade from twisting and cause and can not normally use.
The beneficial effects of the utility model are:
This saw is when work, can as required forniciform saw bow commutation be installed between handle and the installation head, thereby change the distance between saw bow and the saw blade, make an instrument promptly can take into account the bigger workpiece of sawing and be applicable to narrow and small working space, be applicable to different demands.
