During actual operation, the hole expanding device is inserted into the drilled hole, and then the output shaft of the external driving member is connected to the external connection seat 1.2. The external driving member drives the hole expanding pipe 1.1 to rotate through the external connection seat 1.2. At the same time, the hole expanding component 2 can cut the inner wall of the hole to enlarge the hole size; and the elastic member 3.2 in the cleaning component 3 arranged at the end of the hole expanding pipe 1.1 away from the external connection seat 1.2 can pull the adjusting rod 3.1, so that the cleaning head 3.3 abuts against the inner wall of the hole, so as to clean the stone slag residues generated during the cutting of the hole expanding component 2 while the hole expanding component 2 is cutting, thereby ensuring the drilling effect, avoiding damage to the equipment in the subsequent hole caused by the remaining stone slag residues, and meeting the construction requirements of holes with different sizes without replacing the drill bit, effectively improving the efficiency of the drilling operation.

[0027] Based on the above embodiments, an installation cavity 1.1.1 and an adjustment groove 1.1.2 arranged along the length direction of the reaming pipe 1.1 are formed in the reaming pipe 1.1, and the adjustment groove 1.1.2 communicates with the installation cavity 1.1.1; the reaming assembly 2 includes an adjustment structure 2.1 and a reaming head 2.2. The adjustment structure 2.1 includes an adjustment lead screw 2.1.1 and two oppositely arranged adjustment seats 2.1.2. The adjustment lead screw 2.1.1 is rotatably arranged in the installation cavity 1.1.1. The two adjustment seats 2.1.2 are sleeved on the adjustment lead screw 2.1.1 at intervals, and the adjustment seat 2.1.2 is threadedly connected to the adjustment lead screw 2.1.1; the reaming head 2.2 includes a cutter head 2.2.1 and two connecting arms 2.2.2 hinged to the cutter head 2.2.1. The cutter head 2.2.1 is respectively hinged to the two adjustment seats 2.1.2 through the two connecting arms 2.2.2. The adjustment lead screw 2.1.1 can drive the two adjustment seats 2.1.2 to approach or move away from each other to adjust the distance between the cutter head 2.2.1 and the adjustment lead screw 2.1.1. A tool is used to drive the adjustment lead screw 2.1.1 to rotate, so as to drive the two adjustment seats 2.1.2 to approach each other to make the angle between the two connecting arms 2.2.2 smaller, and the two connecting arms 2.2.2 push the cutter head 2.2.1 away from the adjustment lead screw 2.1.1, or the two adjustment seats 2.1.2 move away from each other to drive the cutter head 2.2.1 to approach the adjustment lead screw 2.1.1 through the two connecting arms 2.2.2, so that the drilling size can be flexibly adjusted. During the reaming operation, first, the distance between the two adjustment seats 2.1.2 is adjusted by rotating the adjustment lead screw 2.1.1 according to the set hole diameter size, and then the distance between the cutter head 2.2.1 and the adjustment lead screw 2.1.1 is adjusted. Then, an external driving member is used for driving to drive the reaming head 2.2 to cut the inner wall of the hole, so as to adjust the hole diameter size to the set hole diameter size. The reaming assembly 2 can quickly adjust the hole diameter size without replacing drills of different sizes for drilling, which can not only ensure the smoothness of the hole wall, improve the drilling effect, but also be beneficial to improving the drilling efficiency.

[0028] Wherein, the number of the reaming heads 2.2 is two, and the two reaming heads 2.2 are arranged back to back. The two reaming heads 2.2 cooperate to perform the reaming operation, so that the reaming assembly 2 is stably matched with the inner wall of the hole, improving the operation efficiency, and avoiding wear caused by uneven force during the operation of a single reaming head 2.2, which affects the service life of the reaming head 2.2.

[0029] In another example of this embodiment, the number of the reaming heads 2.2 is more than two, and the more than two reaming heads 2.2 are circumferentially arranged with the central axis of the reaming pipe 1.1 as the center of the circle. Each reaming head 2.2 is circumferentially arranged and cooperates to perform the reaming operation, which not only further improves the operation efficiency and the drilling effect, but also can disperse the force and extend the service life.

[0030] Specifically, an opening 1.1.3 communicating with the installation cavity 1.1.1 is formed at one end of the reaming tube 1.1 away from the cleaning assembly 3, and the outer connecting seat 1.2 extends into the opening 1.1.3 and is detachably connected to the reaming tube 1.1; the adjusting structure 2.1 further includes an adjusting handle 2.1.3, the adjusting handle 2.1.3 is arranged at the opening 1.1.3, and the adjusting handle 2.1.3 is connected to the adjusting screw rod 2.1.1.

The operation is convenient and the flexibility is high. Preferably, the adjusting handle 2.1.3 is also provided with scales corresponding to different drilling sizes, so as to facilitate the operator to accurately adjust the drilling size.

The external tool is provided with a chuck corresponding to the clamping groove B. The output end of the external tool is sleeved on the outer periphery of the adjusting handle 2.1.3, and at the same time, the chuck is clamped with the clamping groove B, and then the rotating tool is rotated to drive the adjusting handle 2.1.3 to rotate. The anti-slip groove C can increase the friction between the adjusting handle 2.1.3 and the external tool and prevent slipping.

[0032] As Figure 3 shown, the reaming device further includes a mounting seat 1.3, the mounting seat 1.3 includes a connected mounting portion 1.3.1, a connecting portion 1.3.2 and a rebounding portion 1.3.3. The connecting portion 1.3.2 is detachably connected to one end of the reaming tube 1.1 away from the outer connecting seat 1.2 through the mounting portion 1.3.1, and the connecting portion 1.3.2 forms a movable groove A.

The cleaning assembly 3 is detachably connected to the reaming tube 1.1 through the mounting seat 1.3, so that the cleaning assembly 3 can be disassembled at any time and the drill bit can be replaced for drilling operations. The elastic member 3.2 is hinged between the rebounding portion 1.3.3 and the second end of the adjusting rod 3.1, so that the elastic member 3.2 can pull the second end of the adjusting rod 3.1 to incline away from the central axis of the reaming tube 1.1. When cleaning holes of different sizes, the cleaning head 3.3 can be kept in contact with the inner wall of the hole, so as to adapt to the cleaning operations of holes of different sizes.

[0033] Among them, the cleaning assembly 3 further includes two hinge seats 3.4, which are respectively arranged on the elastic return part 1.3.3 and the adjusting rod 3.1. The two ends of the elastic member 3.2 are respectively hinged to the two hinge seats 3.4. The elastic member 3.2 is respectively connected to the elastic return part 1.3.3 and the adjusting rod 3.1 through the two hinge seats 3.4, so as to regularly replace the elastic member 3.2 to maintain the close fit between the cleaning assembly 3 and the inner wall of the hole and ensure the cleaning effect.

[0034] In addition, the number of the cleaning assemblies 3 is two, and the two cleaning assemblies 3 are arranged back to back on the connecting part 1.3.2; the two cleaning assemblies 3 cooperate to work, so that the cleaning assembly 3 is stably matched with the inner wall of the hole, improving the working efficiency and avoiding the wear caused by uneven force when a single cleaning assembly 3 works, which affects the service life of the cleaning assembly 3.

[0035] In another example of this embodiment, the number of the cleaning assemblies 3 is more than two, and the more than two cleaning assemblies 3 are circumferentially arranged with the central axis of the reaming pipe 1.1 as the center of the circle. Each cleaning assembly 3 is circumferentially arranged and cooperates to work, which not only further improves the working efficiency and the cleaning effect, but also can disperse the force and extend the service life.
