[0003] The structure and use mode of this kind of magnetic seat drill can have the following problems: 1, when installing drilling cutter, it also needs to artificially exert force to hold up motor, if needing to process hole for multiple times, it also needs to hold up motor for multiple times, thereby increasing the working strength of operator;2, when needing to replace drilling position, it needs to rotate the feed handle clockwise first, lifts the drilling unit to a certain height, makes the drilling cutter higher than the surface of workpiece, then one hand stabilizes the feed handle, makes the drilling cutter always higher than the surface of workpiece, the other hand moves the magnetic seat drill and places it to the next drilling position, if not stabilizing the feed handle, when moving the magnetic seat drill, motor will fall down, causes the drilling cutter and the surface of workpiece to knock, thereby causing the surface of workpiece to be damaged or the drilling cutter to be damaged. UTILITY MODEL CONTENTS
[0004] The utility model aims at providing a kind of magnetic seat drill with feed handle limiting device, it can solve the problem that the existing magnetic seat drill structure needs to artificially exert force to hold up motor when installing drilling cutter, and needs to manually stabilize feed handle when replacing drilling position.
[0005] In order to solve the above problems, the utility model adopts the technical scheme: this magnetic base drill with feed handle limiting device, including the base with feed handle, the feed handle includes the connecting rod that one end is inserted into the base horizontally, the other end of the connecting rod is equipped with a plurality of handle grip, the base is equipped with the movable limiting rod on one side of the connecting rod, one end of the movable limiting rod is hinged with the base, the lower of the movable limiting rod is equipped with the limiting block.
[0006] More specific technical solutions in the above technical scheme can also be: one end of the movable limiting rod is equipped with the recess, the surface of the base is equipped with the positioning block inserted into the recess, the positioning block and the recess are connected through the positioning pin.
[0007] Further, the movable limiting rod is made of a metal material with magnetism.
[0008] Further, the base is equipped with a magnet block above the positioning block.
[0009] Further, the limiting block is equipped with a horizontal support surface on the top.
[0010] Further, the limiting block is connected with the base through the bolt.
[0011] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects compared with the prior art:
[0012] In use, before the installation of the drilling tool is used to cut the workpiece, the feed handle is rotated clockwise first, the drilling unit including the motor and the drill chuck is lifted to a certain height, then the movable limiting rod is rotated outward of the base with the positioning pin as the center shaft, and due to the limitation and support of the limiting block, the movable limiting rod can maintain the open state and clamp the handle grip, so that the feed handle cannot be rotated counterclockwise, and the motor cannot fall downward, the drilling tool is installed in the drill chuck, and the drilling tool is locked, in this process, the motor does not need to be lifted, and the motor also has no falling risk, which reduces the working strength of the operator; when the drilling position needs to be replaced, the magnetic base drill also does not need to manually stabilize the feed handle, so that the operator can use it more simply and labor-savingly.
