[0006] Preferably, the adjustable telescopic fixed support rod includes a supporting sub-rod, a supporting hollow mother rod sleeved on the supporting sub-rod, and a third butterfly bolt screwed and installed on both sides of the supporting hollow mother rod near the top; the supporting sub-rod is damped and slidably installed in the supporting hollow mother rod.

[0007] Preferably, the ends of the third butterfly bolts are pressed against the surface of the supporting sub-rod, a first mounting block is provided at the end of the supporting hollow mother rod, a second mounting block is provided on the wearing belt, and the first mounting block is adjustably mounted on the second mounting block through a fourth butterfly bolt.

[0008] Preferably, the pipeline grooving machine includes a support base, a driving motor embedded in the support base, a wheel protective shell arranged on the support base, a cross mounting shaft arranged at the output end of the driving motor, a cutting and grinding wheel sleeved on the cross mounting shaft, a fixing buckle installed at the end of the cross mounting shaft, a pushing armrest assembly arranged on the support base, and a rolling wheel assembly installed on the support base.

[0009] Preferably, the wheel protective shell comprises an open shell and a cover plate installed at the open end of the side of the open shell, and the cutting and grinding wheel comprises a plurality of cutting wheel wheels and a plurality of grinding wheels interspersed and installed between the plurality of cutting wheel wheels.

[0010] Preferably, several of the cutting wheel rotors and several of the grinding wheels are penetrated by a cross mounting groove adapted to the cross mounting axis, and the pushing armrest assembly includes a first armrest arranged at the front end of the support seat and a second armrest arranged on the upper surface of the support seat away from the cutting wheel rotor.

[0011] Preferably, the rolling wheel assembly includes a roller rotatably mounted in the support base close to the first armrest and a universal wheel mounted on the support base below the second armrest.

[0012] Preferably, the support seat is provided with a snap-fitting fixed shell, the driving motor is installed on the support seat through the snap-fitting fixed shell, the open shell is connected with a discharge suction pipe on the upper side of the snap-fitting fixed shell, a plurality of nozzles are snap-fitted and installed on the side of the open shell, and the plurality of nozzles are connected together by a water inlet pipe, and a wearing buckle is provided on the wearing belt.

[0013] A slotting method for an electrical piping slotting device for building electromechanical installation, comprising the following steps: S1. When using the device, the cover should be opened first, and then several cutting wheels and several grinding wheels should be inserted and sleeved on the cross mounting shaft, and then the fixing buckle should be installed at the end of the cross mounting shaft and locked by bolts. At this time, the end of the discharge suction pipe should be connected to the slag suction device, and then the end of the water inlet pipe should be connected to the water delivery pipe; S2. At this time, the worker can unfasten the buckle on the wearing belt, and then put the wearing belt around the worker's waist, and then fasten and lock the wearing belt with the wearing buckle; S3. At this time, the first butterfly bolt, the second butterfly bolt, the third butterfly bolt and the fourth butterfly bolt are all in a loose state. The worker wearing the wearing belt can stand in front of the working wall, and then stick the bottom of the pipeline slotting machine in his hand to the wall, and then tighten and lock the fourth butterfly bolt, so that the bottom of the adjustable telescopic fixed support rod is fixedly connected with the wearing belt. After that, the worker can carry out debugging before fixing the shared support carrying frame according to the requirements of the slotting and the comfort he feels. S4. After the shared support carrying frame is debugged, other workers can help tighten and fix the third butterfly bolt on the adjustable telescopic fixed support rod, so that the adjustable telescopic fixed support rod can be fixed and locked after being adjusted to the required position, and then tighten the second butterfly bolt between the support sub-rod and the connecting and fixing base, so that the adjustable telescopic fixed support rod and the connecting and fixing base are fixed and locked together, and then the connecting and fixing base and the rotating ball can be selected according to the route of the groove to be cut. S5. When the slotting route is relatively straight, the first butterfly bolt on the connecting and fixing base can be tightened and fixed. At this time, the two first butterfly bolts will squeeze and lock the rotating ball, so that the connecting and fixing base and the rotating ball are in a locked state. This allows the sharing support carrying frame in the device to transfer part of the force of the pipeline slotting machine to the waist of the operator to the greatest extent, thereby reducing the pressure on the arm; S6. When the slotting route is relatively tortuous, the first butterfly bolt on the connecting and fixing base may not be tightened, so that the two first butterfly bolts will not squeeze and lock the rotating ball, so that the connecting and fixing base and the rotating ball are in a state of free rotation, which makes the shared support carrying frame in the device provide the pipeline slotting machine with maximum flexibility, so that it can continue to flexibly turn and slot when facing a relatively tortuous slotting route; S7. When the pipeline grooving machine is in operation, the cutting and grinding wheel will quickly cut and groove the wall surface to be grooved under the rotation of the driving motor. When the wall surface to be grooved is quickly cut and grooved, the external water pipe will transport water to the nozzle through the water inlet pipe. At this time, the nozzle can spray water over a larger area. The sprayed water can reduce dust and quickly cool down the cutting and grinding wheel, thereby preventing the cutting and grinding wheel from overheating. Then the waste cut out will be sucked away by the slag suction device through the discharge suction pipe and temporarily stored.

[0014] The present invention has at least the following beneficial effects: 1. The invention can share part of the mass pressure of the slotting machine on the torso of the worker by cooperating with each other among the connecting rotating rod, the connecting fixed base, the first butterfly bolt, the adjustable telescopic fixed support rod, the second butterfly bolt and the wearing belt in the sharing support carrying frame, so as to distribute the pressure received and effectively reduce the pressure on the arm, so that the worker can be more comfortable when working, and thus the working efficiency can be higher.

[0015] 2. The invention can lock the connection between the fixed base 4 and the rotating ball 11 by tightening the first butterfly bolt 5, so that the shared support carrying frame 2 in the device can transfer part of the force of the pipeline grooving machine 1 to the waist of the operator to the greatest extent, thereby reducing the pressure on the arm.

[0016] 3. The invention can make the connection between the fixed base 4 and the rotating ball 11 in a free rotation state by loosening the first butterfly bolt 5, so that the shared support carrying frame 2 in the device can provide the pipeline grooving machine 1 with maximum flexibility, so that it can continue to flexibly turn and groove when facing a more tortuous grooving route.

The electrical conduit slotting device for building mechanical and electrical installation according to claim 6, characterized in that: The support seat (20) is provided with a snap-fit ​​fixed housing (36), the drive motor (21) is mounted on the support seat (20) via the snap-fit ​​fixed housing (36), the open housing (28) is provided with a discharge suction pipe (37) on the side above the snap-fit ​​fixed housing (36), a plurality of nozzles (38) are snap-fitted and mounted on the side of the open housing (28), the plurality of nozzles (38) are connected together via a water inlet pipe (41), and a wearing buckle (25) is provided on the wearing belt (8).

10. A grooving method for the electrical piping grooving device for building mechanical and electrical installation according to claim 9, characterized in that: The following steps are involved: S1. When the device is used, the cover plate (29) should be opened first, and then a plurality of cutting wheel wheels (30) and a plurality of grinding wheel wheels (31) are inserted and inserted into the cross mounting shaft (22), and then the fixing buckle (40) is installed at the end of the cross mounting shaft (22) and fixed and locked by bolts. At this time, the end of the discharge suction pipe (37) is connected to the slag suction device, and then the end of the water inlet pipe (41) is connected to the water supply pipe; S2, the worker can then unfasten the wearing buckle (25) on the wearing belt (8), and then put the wearing belt (8) around the worker's waist, and then fasten and lock the wearing belt (8) through the wearing buckle (25); S3. At this time, the first butterfly bolt (5), the second butterfly bolt (7), the third butterfly bolt (16) and the fourth butterfly bolt (19) are all in a loose state. The worker wearing the wearing belt (8) can stand in front of the working wall, and then stick the bottom of the pipeline slotting machine (1) in his hand to the wall, and then tighten and lock the fourth butterfly bolt (19) so that the bottom of the adjustable telescopic fixed support rod (6) is fixedly connected to the wearing belt (8). After that, the worker can debug the shared support carrying frame (2) before fixing it according to the requirements of the slotting and the comfort he feels. S4. After the shared support carrying frame (2) is debugged, other workers can help tighten and fix the third butterfly bolt (16) on the adjustable telescopic fixed support rod (6), so that the adjustable telescopic fixed support rod (6) can be fixed and locked after being adjusted to the desired position, and then tighten the second butterfly bolt (7) between the support sub-rod (14) and the connecting and fixing base (4), so that the adjustable telescopic fixed support rod (6) and the connecting and fixing base (4) are fixed and locked together, and then the connecting and fixing base (4) and the rotating ball (11) can be selected according to the route of the groove to be cut. S5. When the slotting route is relatively straight, the first butterfly bolt (5) on the connecting and fixing base (4) can be tightened and fixed. At this time, the two first butterfly bolts (5) will squeeze and lock the rotating ball (11), so that the connecting and fixing base (4) and the rotating ball (11) are in a locked state, so that the sharing support carrying frame (2) in the device can transfer part of the force of the pipeline slotting machine (1) to the waist of the operator to the greatest extent, thereby reducing the pressure on the arm; S6. When the slotting route is relatively tortuous, the first butterfly bolt (5) on the connecting and fixing base (4) may not be tightened. At this time, the two first butterfly bolts (5) will not squeeze and lock the rotating ball (11), so that the connecting and fixing base (4) and the rotating ball (11) are in a state of free rotation. This allows the shared support carrying frame (2) in the device to provide the pipeline slotting machine (1) with maximum flexibility, so that the pipeline slotting machine (1) can continue to flexibly turn and slot when facing a relatively tortuous slotting route; S7. When the pipeline slotting machine (1) is in operation, the cutting and grinding wheel (23) will quickly cut and grind the wall surface to be slotted under the rotation of the driving motor (21). When the wall surface to be slotted is quickly cut and grind, the external water pipe will transport water to the nozzle (38) through the water inlet pipe (41). At this time, the nozzle (38) can spray water over a large area. The sprayed water can reduce dust and quickly cool the cutting and grinding wheel (23), thereby preventing the cutting and grinding wheel (23) from overheating. Then, the waste cut out will be sucked away by the slag suction device through the discharge suction pipe (37) and temporarily stored.
