[0031] Example 1

[0032] Reference Figures 1-2 , which is the first embodiment of the utility model, and this embodiment provides a fixed installation mechanism.

[0033] The support assembly 100 is used to provide support for the fixed installation mechanism. The support rod 101 is located at the bottom of the whole mechanism and can be fixedly connected to a matching structure of any shape and structure to assist the staff in grasping the support rod 101. The top of the support rod 101 is fixedly provided with a mounting assembly 102, which is used to accommodate the work of the fixed matching limit assembly 200.

[0034] The mounting assembly 102 is internally rotatably provided with a matching sleeve 201, which is used to work with the plug-in rod 304 provided at the bottom of the polishing assembly 300. The inner wall of the matching sleeve 201 is fixed with an oblique thread for docking with the plug-in rod 304, and the outer wall of the plug-in rod 304 is provided with a convex block corresponding to the oblique thread. When the convex block is aligned with the oblique thread, the plug-in rod 304 enters the matching sleeve 201, which can drive the matching sleeve 201 to rotate.

[0035] The locking unit 202 is arranged at the bottom of the matching sleeve 201 and the inner wall of the mounting assembly 102. The matching sleeve 201 gradually rotates when the plug-in rod 304 enters, and finally locks with the locking unit 202 after rotating ninety degrees. After the matching sleeve 201 is fixed, the plug-in rod 304 cannot be removed at will due to the action of the oblique thread, thereby ensuring that the plug-in rod 304 and the polishing assembly 300 are securely installed.

[0036] The power output end 301 is located at the center of the polishing assembly 300. The bottom of the power output end 301 is immovable, and the entire polishing assembly 300 can be firmly fixed while being fixedly connected to the plug rod 304. The transmission sleeve 302 is fixedly connected to the outer wall of the rotatable end of the power output end 301. When the power output end 301 starts to start, it can drive the transmission sleeve 302 to rotate, and the stainless steel pipe can be quickly processed and polished.

[0037] Example 2

[0038] Reference Figures 1 to 4, which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the structure of the support assembly 100 and the matching structure of the locking assembly 200 are further optimized.

[0039] A receiving groove 102a is fixedly provided on the top of the mounting assembly 102, and the receiving groove 102a itself is rotationally connected to the matching sleeve 201. A threaded bevel groove 201a is fixedly provided on the inner wall of the matching sleeve 201 to cooperate with the plug-in rod 304. A protrusion with a corresponding oblique thread is provided on the outer wall of the plug-in rod 304. When the protrusion is aligned with the threaded bevel groove 201a and enters the matching sleeve 201, it can drive the matching sleeve 201 to rotate.

[0040] An adjustment cavity 102b is provided below the receiving groove 102a, and the bottom of the matching sleeve 201 is located in the adjustment cavity 102b. Two symmetrical receiving rods 201b are fixedly provided at the bottom of the matching sleeve 201, and the receiving rods 201b will rotate following the cooperation of the matching sleeve 201 and the plug-in rod 304. A rebound groove 201b-1 is fixedly provided inside the receiving rod 201b, and a spring telescopic rod 201c is fixedly provided at the bottom of the rebound groove 201b-1. A limiting ball 201c-1 is fixedly provided at the other end of the spring telescopic rod 201c toward the opening of the rebound groove 201b-1, and the outside of the limiting ball 201c-1 is located outside the rebound groove 201b-1.

[0041] The inner wall of the locking unit 202 is fixedly provided with a blocking groove 202a, and the blocking groove 202a is used to directly cooperate with the limiting ball 201c-1. When the limiting ball 201c-1 rotates following the rotation of the matching sleeve 201, it can contact the surface of the locking unit 202, and the limiting ball 201c-1 is squeezed at this time, and the spring telescopic rod 201c can give the limiting ball 201c-1 an elastic force to reset. When the limiting ball 201c-1 moves to the maximum limit, it can enter the blocking groove 202a, and the spring telescopic rod 201c drives the limiting ball 201c-1 to pop out and cooperate with the blocking groove 202a, and the entire matching sleeve 201 can no longer rotate and is firmly fixed by the locking unit 202.

[0042] An unlocking slider 203 is disposed on the other side of the blocking groove 202a. The end of the unlocking slider 203 penetrates the blocking groove 202a and enters one side of the blocking groove 202a. The end of the unlocking slider 203 is configured as a rounded surface. When the limiting ball 201c-1 finally enters the blocking groove 202a, the end of the unlocking slider 203 can be pushed out of the blocking groove 202a. Conversely, if a thrust is applied to the unlocking slider 203 from the outside, the limiting ball 201c-1 can be pushed out of the blocking groove 202a again, so that the two are misaligned. At this time, the matching sleeve 201 is no longer restricted, and the polishing assembly 300 and the installation assembly 102 can be disassembled and separated by manually pulling.

[0043] An outer wall of the mounting assembly 102 is fixed with an embedded groove 102c, and the top outer part of the unlocking slider 203 slides along the embedded groove 102c. When the limiting ball 201c-1 and the blocking groove 202a are completely in contact, the unlocking slider 203 will be pushed out along the embedded groove 102c. This is convenient for the staff to observe and determine whether the matching sleeve 201 has been fixed, and it is also convenient for the staff to unlock.

[0044] Example 3

[0045] Reference Figures 1 to 5 , which is the third embodiment of the utility model. This embodiment is based on the above embodiment and adds a pipe mouth burr grinding device.

[0046] The power output end 301 is located at the center of the polishing assembly 300. The bottom of the power output end 301 is immovable. When the plug rod 304 is fixedly connected, the entire polishing assembly 300 can be firmly fixed. The transmission sleeve 302 is fixedly connected to the outer wall of the rotatable end of the power output end 301. When the power output end 301 starts, it can drive the transmission sleeve 302 to rotate and quickly process and polish the stainless steel pipe. A connecting rod 302a is fixedly set on the outer wall of the transmission sleeve 302, and a grinding wheel 303 is fixedly set at the other end of the connecting rod 302a. A gap is reserved between the grinding wheel 303 and the transmission sleeve 302, which can reduce the weight and avoid the accumulation of debris and dust left over from grinding.

[0047] The outer wall of the grinding wheel 303 is fixedly provided with a grinding sheet 303a, which can process the inner wall of the stainless steel pipe, further improving the polishing effect of the stainless steel pipe and reducing the probability of scratches when the staff is handling it. The top of the grinding wheel 303 is fixedly provided with an auxiliary wheel 303b. Under the drive of the power output end 301, the rotation of the grinding wheel 303 drives the rotation of the auxiliary wheel 303b, which can grind the vertical section of the stainless steel pipe mouth.
