[0025] By adopting the above technical scheme, when it is necessary to use the driving mechanism 5 to expand the materials required for the construction of the construction project, the water pump 72 is started. Under the action of the water pump 72 and the elastic bellows 74, the cold water inside the water tank 73 can be transported to the inside of the annular tube 76, and then sprayed to the expanding component under the driving mechanism 5 through the nozzle 75, and the expanding component under the driving mechanism 5 is water-cooled to avoid the temperature of the expanding component under the driving mechanism 5 being too high during the expanding process, thereby avoiding damage to the expanding component under the driving mechanism 5. The water after water cooling flows into the collecting component 71 for collection operation.
[0026] Specifically, the collecting member 71 includes an L-shaped plate 711, a collecting port 712, a collecting box 713, a separation net cylinder 714 and a support block 715.

Under the action of the water pump 72 and the elastic bellows 74, the cold water in the water storage tank 73 can be transported to the inside of the annular pipe 76, and then sprayed The head 75 sprays onto the hole-expanding component below the driving mechanism 5, and performs water cooling on the hole-expanding component below the driving mechanism 5 to avoid excessive temperature of the hole-expanding component below the driving mechanism 5 during the hole-expanding process, thereby preventing the hole-expanding component below the driving mechanism 5 from being damaged. The water after water cooling and the debris generated during the hole-expanding process fall into the collection box 713 through the collection port 712, and the water falls into the collection box 713 through the pores on the separation net cylinder 714. The debris generated during the hole-expanding process remains in the separation net cylinder 714, which facilitates the separate collection of water and debris.

[0032] The present embodiment is different from the embodiment 1 in that the storage and placement assembly 4 includes a placement box 41, a reaming drill 43, a top plate 44 and a placement groove 46. The side wall of the workbench 1 is connected with the placement box 41, a plurality of reaming drills 43 are arranged inside the placement box 41, a placement groove 46 is arranged above the placement box 41, and a top plate 44 is arranged inside the placement groove 46.
[0033] Specifically, the storage and placement component 4 further includes a plug hole 42 and a plug board 45. The inside of the placement box 41 is connected to the plug board 45. The plug hole 42 is arranged on the plug board 45 and is located on the periphery of the reamer 43.

[0037] The structure and principle of the driving mechanism 5 composed of a guide column, a first spring, a sliding plate, a motor, a mounting shell, a clamping rod, and a second spring in the utility model have been disclosed in Chinese patent application No. 202321992175.6, which discloses a hole expander for construction engineering. Its working principle is: guide columns are connected to both ends of the upper part of the workbench 1 and located inside the bracket 2, the outer periphery of the guide column is sleeved with a first spring, a sliding plate is arranged between the two guide columns and located above the second spring, a motor is installed at the bottom of the sliding plate through a mounting frame, the output shaft of the motor is connected to the mounting shell through a coupling, clamping rods are passed through both sides of the mounting shell, the clamping rods are L-shaped, and A square plate is provided on the part of the mounting shell where the clamping rod is located, and a second spring is connected to one end of the clamping rod located inside the mounting shell. When in use, the clamping rods on both sides are pressed to insert the reamer 43 into the mounting shell, and then the clamping rods on both sides are released. The clamping rods on both sides are reset under the action of the second spring to clamp and fix the reamer 43. When reaming, the sliding plate is moved down to drive the protective mechanism 6 to contact the building materials on the workbench 1, and then continue to press down, so that the protective mechanism 6 slides up on both sides of the motor. Under the action of the protective mechanism 6, the debris generated during reaming can be prevented from splashing, and then the motor is used to drive the mounting shell to rotate, thereby driving the reamer 43 to rotate to perform the reaming operation.
[0038] The structure and principle of the protective mechanism 6 composed of a protective cover, a guide rod and a third spring in the utility model have been disclosed in Chinese patent application No. 202321992175.6, which discloses a reamer for construction engineering. Its working principle is: guide rods are slidably arranged on both sides of the motor component mounting frame in the driving mechanism 5, and the guide rods are sleeved with a third spring. The guide rods are jointly connected with a protective cover, and the mounting shell component and the reaming drill 43 in the driving mechanism 5 are both inside the protective cover. The protective cover protects the mounting shell component and the reaming drill 43 in the driving mechanism 5. The coupling of the output shaft of the motor component in the driving mechanism 5 passes through the top of the protective cover. When in use, the driving mechanism 5 is moved downward to drive the protective cover to move downward. After the protective cover is attached to the surface of the building material, the driving mechanism 5 continues to be moved downward. The protective cover is squeezed by the building material and moves along the guide rod. The protective cover moves and squeezes the third spring. In the subsequent reaming operation of the reaming drill 43, the splashing of debris can be avoided under the action of the protective cover.
[0039] The working principle and use process of the utility model: during the construction process of the construction project of the utility model, when it is necessary to expand the hole of the building material, the top plate 44 is moved upwards to make the top plate 44 away from the placement groove 46, and then the corresponding expansion drill 43 is found from the inside of the placement box 41 according to the aperture size of the expansion hole required by the building material, and then the expansion drill 43 is moved upwards to make the expansion drill 43 away from the plug-in hole 42 on the plug-in plate 45, and then the existing expansion drill 43 on the driving mechanism 5 is removed, and the expansion drill 43 taken out from the inside of the placement box 41 is installed on the driving mechanism 5, and then the removed expansion drill 43 is plugged into the vacant plug-in hole 42, so as to facilitate the disassembly, assembly and replacement operation of the expansion drill 43 and improve the processing efficiency, and the building material is placed on the workbench 1, and then the driving mechanism 5 is moved downward along the bracket 2, and the downward movement of the driving mechanism 5 drives the protective mechanism 6 to move downward to fit the surface of the building material, so as to prevent the expansion drill 43 from being damaged. The protective mechanism 6 moves downward to drive the elastic bellows 74 to expand and contract, and then the water pump 72 is started. At the same time, the driving mechanism 5 is used to drive the reaming drill 43 to expand the building materials. Under the action of the water pump 72 and the elastic bellows 74, the cold water in the water storage tank 73 can be transported to the inside of the annular tube 76, and then sprayed to the reaming drill 43 below the driving mechanism 5 through the nozzle 75, and the reaming drill 43 below the driving mechanism 5 is water-cooled to prevent the reaming drill 43 below the driving mechanism 5 from being too high during the reaming process, thereby preventing the reaming drill 43 below the driving mechanism 5 from being damaged. The water after water cooling and the debris generated during the reaming process fall into the collection box 713 through the collection port 712, and the water falls into the collection box 713 through the pores on the separation net cylinder 714. The debris generated during the reaming process remains in the separation net cylinder 714, which is convenient for realizing the separate collection operation of water and debris.
