Изобретение относитс к ручному деревообрабатывающему инструменту и может быть использовано дл выпиливани деталей с криволинейными контурами.The invention relates to a manual woodworking tool and can be used for cutting out parts with curvilinear contours.
Известен лобзик, включающий скобу с ручкой, установленные на концах скобы зажимные с;,товр; ра с закрепленным в них пильным |поло™ом,Known jigsaw, including bracket with a handle mounted on the ends of the bracket clamping with; tov; pa with the saw | polo ™ set in them,
Недостаткам Данного устройства вл етс заранее опр в ирлий длина пильного полотна, рпр.едел е1у5а рассто нием между концами скобы 4т& разрыве пильного полотна исключ у..вд1з.1 6жность дальнейшего использовани обеих его половин. Это, в свою очередь, приводит к повышенному расходу пильных полотен.The disadvantages of this device are to determine in advance the length of the saw blade, ie the length of the distance between the ends of the shackle 4 t & rupture of the saw blade is excluded. .. vd1z.1 6ness of the further use of both its halves. This, in turn, leads to increased consumption of saw blades.
Цель изобретени - уменьшение расхода пильных полотен.The purpose of the invention is to reduce the consumption of saw blades.
Цель достигаетс тем, что лобзик, включающий скобу с ручкой, установленные на концах скобы зажимные устройства с закрепленным в них пильным полотном, снабжен катушкой, ручка выполнена полой, а пильное полотно имеет длину, превышающую рассто ние между концами скобы, причем избыток пильного полотна намотан на катушку, котора размещена в полой ручке.The goal is achieved by the fact that the jigsaw, including a bracket with a handle, clamping devices mounted on the ends of the bracket with a saw blade fixed in them, is provided with a coil, the handle is made hollow, and the saw blade has a length exceeding the distance between the ends of the bracket, and the excess saw blade is wound on a coil that is placed in a hollow handle.
На чертеже показан лобзик с ручкой, общий вид, разрез.The drawing shows a jigsaw with a handle, a general view, a slit.
Лобзик содержит скобу 1, а также ручку 2 с полостью, в которую вставл етс катущка 3 с намотанной на нее тонкой стальной проволокой с насечкой на поверхности, котора и служит пильным полотном. На концах скобы 1 установлены зажимные устройства 4 и 5, в которых зажат рабочий отрезок 6 пильного полотна.The jigsaw contains a bracket 1, as well as a handle 2 with a cavity into which the roller 3 is inserted with a thin steel wire wound around it with a notch on the surface, which serves as a saw blade. At the ends of the bracket 1, clamping devices 4 and 5 are installed, in which the working length 6 of the saw blade is clamped.
Лобзик работает следующим образом.Jigsaw works as follows.
Перед началом работы в полость ручки 2 вставл етс катушка 3. Конец намотанной на нее пилки пропускаетс в отверстие в скобе лобзика и катушка закрепл етс завинчиваемой крышкой. Конец пилки выт гиваетс на необходимую длину. Свободный конец пилки закрепл етс зажимным устройством 5, и лобзик готов к работе .Before starting work, the coil 3 is inserted into the cavity of the handle 2. The end of the file wound around it is passed into the hole in the jigsaw bracket and the coil is fixed with a screw-on cap. The end of the file is stretched to the required length. The free end of the file is fixed by the clamping device 5, and the jigsaw is ready for operation.
При обрыве пильного полотна освобождаютс зажимные устройства 4 и 5, конец пильного полотна выт гиваетс на необходимую длину и закрепление его в скобе лобзика производитс тем же пор дком.When the saw blade is broken, the clamping devices 4 and 5 are released, the end of the saw blade is pulled out to the required length and its fixation in the jigsaw bracket is done in the same order.
Таким образом, изобретение позволит приблизительно вдвое уменьшить расход пильного полотна.Thus, the invention will approximately halve the consumption of the saw blade.
