[0029] like Figure 1-3As shown, the fixing mechanism 2 is arranged on the supporting mechanism 1, and the fixing mechanism 2 is used to fix the steel pipe and align the center of the steel pipe with the drilling mechanism 3. The fixing mechanism 2 includes: a fixing seat 21, a movable component 22 and a fixing component 23. The fixing seat 21 is arranged on the supporting mechanism 1, and through grooves 211 are arranged at both ends of the top of the fixing seat 21. The movable component 22 includes a screw 222 and two movable blocks 221. The two movable blocks 221 are slidably arranged in the fixing seat 21, and an internal thread is arranged at the center of the two movable blocks 221. The internal threads of the two movable blocks 221 are symmetrically arranged, and the screw 222 is rotatably arranged in the base. Two sections of external threads are arranged on the screw 222, and the two sections of external threads are respectively matched with the two sections of internal threads. The central axis of the screw 222 is recorded as a first straight line, and the first straight line is collinear with the line connecting the midpoints of the two movable blocks 221. The fixing assembly 23 includes two baffles 232 and four connecting rods 231. The two baffles 232 are symmetrically opened and closed about the first straight line; each baffle 232 is hinged to one end corresponding to the two movable blocks 221 through two connecting rods 231. Specifically, the two connecting rods 231 are not parallel but arranged at an angle, one end of the connecting rod 231 is hinged to the movable block 221, and the other end of the connecting rod 231 is hinged to the baffle 232. The baffle 232 includes a first part 2321, a second part 2322 and a third part 2323. The first part 2321 is hinged to the other end of the connecting rod 231. There are two second parts 2322. The two second parts 2322 are connected to the top of the first part 2321, and the two second parts 2322 are vertically arranged at both ends of the first part 2321 respectively. The two second parts 2322 correspond to the two through grooves 211. The second part 2322 is embedded in the through groove 211 and slides along the through groove 211. The third part 2323 is located above the base, and the bottom of the third part 2323 is connected to the top of the two second parts 2322.

[0030] In other embodiments, multiple fixing mechanisms 2 may be provided, and the multiple fixing mechanisms 2 are arranged along the length direction of the first straight line, and the screws 222 of the multiple fixing mechanisms 2 are all connected. The rotation of one screw 222 can drive the screws 222 of multiple fixing mechanisms 2 to rotate simultaneously.

[0031] like Figure 4As shown, the drilling mechanism 3 is used for drilling holes in the steel pipe. The drilling mechanism 3 includes a support seat assembly 31 arranged on the support mechanism 1 and a plurality of drilling assemblies 32 arranged on the support seat assembly 31. The support seat assembly 31 includes a lead screw, a nut, a guide rod, a slider and a connecting seat 311. The lead screw is vertically arranged on the support seat assembly 31 and rotates along the central axis. The nut is matched with the lead screw, and the nut is connected to the connecting seat 311; the guide rod is vertically arranged on the support seat assembly 31, the slider is sleeved on the guide rod and slidably arranged, the slider is connected to the connecting seat 311, and the slider and the nut are located on the same side of the connecting seat 311. The other side of the connection seat 311 is connected to a plurality of drilling assemblies 32, wherein a slideway 3111 is provided on the other side of the connection seat 311, the length direction of the slideway 3111 is the same as the length direction of the first straight line, and a slide groove 322 corresponding to the slideway 3111 is provided on the drilling assembly 32, and the drilling assembly 32 slides along the slideway 3111, and the drilling assembly 32 is fixed to the connection seat 311 by bolts 33, and the arrangement of the bolts 33 is convenient for disassembly and assembly, and when the bolts 33 are removed, the drilling assembly 32 can slide, and the bolts 33 can be installed to fix the drilling assembly 32 to the connection seat 311. The drilling assembly 32 includes a drill bit 321, and the drill bit 321 is located above the first straight line.

[0032] When in use, first adjust the position of the drilling assembly 32, remove the bolt 33, release the fixation of the drilling assembly 32 and the connecting seat 311, and move the drilling assembly 32 along the slide 3111 to a suitable position, so that the bolt 33 fixes the drilling assembly 32 on the connecting seat 311, and adjust the position of each drilling assembly 32 one by one according to the above steps. The screw rod 222 is rotated, and the screw rod 222 rotates to drive the two movable blocks 221 to move in opposite directions. The two movable blocks 221 drive the two connecting rods 231 to rotate, and the angle between the two connecting rods 231 is reduced, driving the baffle 232 to move away from the first straight line. Therefore, the distance between the two baffles 232 increases. The steel pipe is placed between the two baffles 232, and the screw rod 222 is rotated in the opposite direction, so that the screw rod 222 drives the two movable blocks 221 to move in opposite directions. The two movable blocks 221 drive the two connecting rods 231 to rotate, so that the angle between the two connecting rods 231 increases, and drives the baffle 232 to move close to the first straight line, that is, the distance between the two baffles 232 is reduced and the steel pipe is clamped to fix the steel pipe. The steel pipe can be drilled by controlling the multiple drilling assemblies 32 to move downward. Even if the lead screw rotates, the nut is driven to move downward along the lead screw, and the drill bits 321 of the multiple drilling assemblies 32 can be driven to drill holes at the center of the steel pipe.

[0033] In the present invention, the drill bit 321 of the drilling mechanism 3 and the connecting line of the midpoints of the two movable blocks 221 are in the same vertical plane, so that it can be ensured that no matter whether the cross section of the steel pipe is round or square, no matter how large the size of the steel pipe is, a hole can be drilled in the middle of the steel pipe. Moreover, the setting of the fixing mechanism 2 can not only fix the steel pipe, but also fix steel pipes of different sizes, and has universal applicability.

[0034] The setting of the drilling mechanism 3 can facilitate the adjustment of the positions of multiple drilling assemblies 32. After the adjustment is completed, the drilling assemblies 32 are fixed to the connecting frame by bolts 33, so that the drilling assemblies 32 are more stable during the drilling process, thereby ensuring the drilling precision of the device.

[0035] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
