When the electrical pipes are cut in the wall grooves, the decoration workers mostly use cutting machines to cut the grooves on the wall.

[0003] According to the public patent 202120600554.0, a grooving device for electrical pipes for building mechanical and electrical installations includes: a groover body with a water inlet on the top, a circular cutting blade arranged on the groover body through a rotating shaft, and a water tank arranged in the groover body and connected to the water inlet through a water inlet pipe. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The high-pressure nozzle connected to the water tank through a water outlet pipe and the water spray direction facing the cutting blade, and the water volume control structure that controls the water output of the water tank solve the problem of not being able to automatically cool the cutting blade. During use, the traditional grooving device for electrical pipes for building mechanical and electrical installations cannot select grooving wheels of different sizes according to the diameter of different pipes for grooving. The operator is slow in replacing the grooving wheel, and needs to use a disassembly tool to disassemble and replace the grooving wheel, which reduces the convenience of the electrical pipe grooving device during use. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: a grooving device for electrical pipes for building mechanical and electrical installation is designed, including a support arm, a sleeve arm is installed at one end of the support arm, the sleeve arm is connected to an extension arm through a threaded rod, a threaded groove is opened inside the extension arm, one end of the threaded rod is provided with a crank, the other end of the extension arm is connected to a mounting sleeve through a connecting arm, a driving motor is fixedly connected to the inside of the mounting sleeve, a plug connector is fixedly connected to the output end of the driving motor, the other end of the support arm is rotatably connected to a mounting disk, a plurality of slotted wheels of different sizes are rotatably connected around the mounting disk, a plug-in groove is opened in the middle of the other side of the plurality of slotted wheels of different sizes, a limiting hole corresponding to the position of the plurality of slotted wheels of different sizes is opened on the other side of the mounting disk, a limiting screw pin is installed inside the limiting hole, and a fixing plate is installed outside the limiting screw pin.

[0006] Preferably, one end of the sleeve arm is fixedly connected to one end of the support arm, and the other end of the sleeve arm is sleeved on the outside of the extension arm and slidably connected to the outer surface of the extension arm.

[0007] Preferably, one end of the threaded rod is rotatably connected to the inner wall of the sleeve arm, and passes through the interior of the sleeve arm and the support arm to be fixedly connected to one end of the crank, and the other end of the threaded rod is connected to the interior of the thread groove through a thread.

[0008] Preferably, one end of the connecting arm is fixedly connected to the other end of the extending arm, and the other end of the connecting arm is fixedly connected to the top end of the mounting sleeve.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines a sleeve arm, a threaded rod, an extension arm, a threaded groove, a crank, a driving motor, a plug connector, a mounting plate, a slotted wheel, a plug connector groove, a limiting hole and a limiting screw pin. When the slotted wheel of the slotting device needs to be replaced, an operator first rotates the crank so that the crank drives the threaded rod to rotate inside the threaded groove, thereby moving the extension arm out of the sleeve arm. At this time, the extension arm drives the plug connector on the driving motor to be separated from the plug connector groove through the connecting arm and the mounting sleeve. The plug connector and the plug connector groove are disassembled and assembled in a plug-in manner, thereby saving time when disassembling and assembling the plug connector and the slotted wheel.

[0013] The limiting screw is then unscrewed from the inside of the limiting hole, and the mounting plate is then rotated on the support arm, so that the slotting wheel to be used is rotated to the position of the driving motor, and the plug connector is finally moved to the inside of the plug slot, so that slotting wheels of different sizes can be selected for slotting according to the diameters of different pipes, which speeds up the operator's replacement of the slotting wheel and avoids the use of disassembly and assembly tools to disassemble and replace the slotting wheel, thereby improving the convenience of the electrical pipe slotting device during use.
