Description

Technical Field

[0001] The utility model relates to the technical field of lithium-electric jigsaws, in particular to a lithium-electric jigsaw with a stable structure. Background Art

[0002] Lithium-powered jigsaws are mainly used for cutting metals and non-ferrous metals. They have better chip handling when cutting metals. They have larger teeth, which are more efficient when cutting wood and other wood products. Carbon steel jigsaws are used for cutting all types of wood and non-metals. They have sharpened, conical teeth, which cut faster and have better chip handling.

[0003] When you need to cut some objects, you need to use a lithium-electric jigsaw to cut the objects into the required shape and size.

[0004] When using the lithium-electric jigsaw, the user's arm needs to always apply vertical downward force to the lithium-electric jigsaw. Because the motor and other components of the lithium-electric jigsaw are located at the back of the jigsaw, the center of gravity of the lithium-electric jigsaw is tilted backward. Long-term use of force will cause fatigue of the user, resulting in unstable movement of the jigsaw and resulting in cutting failure.

[0005] Moreover, when cutting an object with an existing lithium electric jigsaw, it is necessary to draw a line on the object in advance and then cut it. The existing jigsaw cannot prevent deviation when moving. Utility Model Content

[0006] The purpose of the utility model is to provide a lithium-electric jigsaw with a stable structure to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a lithium-ion curved saw with a stable structure, comprising a curved saw body and an extension plate located at the bottom of the curved saw body; the bottom of the curved saw body is connected to a base plate by a fastener, an extension plate is provided on one side of the base plate, one end of the extension plate is connected to the base plate by embedding, the extension plate is connected to a first threaded column by a thread, one end of the first threaded column is connected to a support plate at the top by a rotating shaft, the bottom of the support plate is connected to a pulley by rotating, one end of the base plate is connected to one side of a connecting column by a fastener, one end of the connecting column is connected to one end of a support rod by embedding, and a guide plate is provided at one end of the support rod away from the connecting column.

[0008] Preferably, the base plate is connected to a fixing bolt via a thread, one end of the fixing bolt is connected to the extension plate by extrusion, the support plate is connected to one end of the sliding rod via a fastener, and the other end of the sliding rod penetrates and connects to the extension plate.

[0009] Preferably, the connecting column is connected to the limiting bolt through a threaded connection, one end of the limiting bolt is connected to the support rod through extrusion, and one end of the support rod away from the connecting column is connected to the support column through a fastener.

[0010] Preferably, one end of the support column is connected to the telescopic column in an embedded manner, and one end of the telescopic column away from the support column is connected to the guide plate through a fastener.

[0011] Preferably, a second threaded column is provided on the outer wall of the support column, two ends of the second threaded column are connected to the outer wall of the support column via a rotating shaft, and the second threaded column is connected to the threaded block via a thread.

[0012] Preferably, one end of the threaded block away from the second threaded column is connected to the telescopic column by welding, and the threaded block passes through the support column.

[0013] Preferably, the pulleys are symmetrically distributed on the support plate, the support plate is mirror-distributed on the bottom plate, and the guide plates are stacked.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model can support the jig saw by providing an extension plate and a pulley to prevent the jig saw from being unstable when moving. When it is necessary to cut an object, the fixing bolt is rotated so that the fixing bolt no longer squeezes the extension plate, and then the extension plate is pulled to make the extension plate drive the pulley to move to a certain length, and then the fixing bolt is rotated in the opposite direction to limit the extension plate, and the first threaded column is rotated, and the first threaded column moves downward on the extension plate through the thread, so that the pulley is supported on the object, and the jig saw is opened to push the jig saw to move. The jig saw moves through the pulley, and through the support of the pulleys on both sides and the rear end, it is only necessary to pull the jig saw to move, which effectively prevents the user from using vertical downward force on the jig saw for a long time, causing the jig saw to tilt when exhausted, saving time and effort and improving work efficiency.

[0016] Secondly, the utility model can guide the curved saw during movement by providing a guide plate and a second threaded column. Before using the curved saw, the limit bolt is rotated so that the limit bolt no longer squeezes and limits the support rod, and the support rod is pulled to move so that the guide plate is located at the corner of the cutting object, and then the second threaded column is rotated. The second threaded column drives the threaded block to move through the thread, and the threaded block drives the telescopic column to move downward, and the telescopic column drives the guide plate to engage at the corner of the object. When the curved saw moves, the guide plate is attached to the corner of the object. The guidance of the guide plate at the corner of the object can prevent the curved saw from being offset and tilted, and there is no need to draw lines on the object in advance, which reflects the practicality of this device.
