Description

Technical Field

[0001] The utility model relates to the technical field of drilling tools, in particular to a door and window frame drilling tool. Background Art

[0002] When fixing and installing the door and window frames, it is necessary to drill holes in the frames and walls for installation. When drilling holes in the frames and walls, the existing drilling tool uses the motor to start to control the rotation and lifting of the drill bit to achieve drilling holes in the frames and walls. Due to the meshing connection of the gears, the shaft sleeve is rotated and the rotation of the rotating rod is controlled to lift the drill bit, so it is not convenient to lift the drill bit when the drill bit is rotating.

[0003] For example, the Chinese patent application number CN202221156157.X is a drilling tool for door and window frames, in which the barrel is fixedly mounted on the right end face of the contact plate, multiple groups of slide grooves are evenly distributed inside the barrel, multiple groups of sliders are slidably mounted in the multiple groups of slide grooves, the first slider and the second slider are both slidably mounted inside the barrel, and the first slider and the second slider are both fixedly connected to the multiple groups of sliders, the first slider is on the left side of the second slider, the second slider is interconnected with the propulsion assembly, the propulsion assembly is mounted inside the barrel, the motor is fixedly mounted on the left end face of the second slider through a fixed seat, the motor output end passes through the first slider and is fixedly connected to the chuck, the drill bit is fixedly mounted on the chuck, and a through hole is provided on the contact plate, through which the drill bit and the chuck can pass. It has the following technical defects:

[0004] When the motor is working, it controls the drill bit to rotate, and then utilizes the meshing connection between the third gear and the fourth gear to control the two sets of shaft sleeves to drive the two sets of rotating rods to rotate synchronously in the same direction, thereby driving the drill bit to rise and fall. However, due to the cooperation between the shaft sleeve and the rotating rod through the limit groove and the long sliding key, the shaft sleeve moves up and down, which easily causes the third gear and the fourth gear to collide when the motor moves up and down, making it inconvenient to raise and lower the drill bit, and thus not conducive to drilling holes in door and window frames. Utility Model Content

[0009] Furthermore, the lifting component 1 includes a gear 2 meshingly connected to the gear 1, and a screw 1 for driving the support plate to lift and lower is inserted into the middle of the left side of the gear 2.

[0010] Furthermore, the lifting component 2 includes a gear 3 meshingly connected with the gear 1, and a screw 2 for driving the support plate to lift and lower is inserted into the middle of the left side of the gear 3.
