Pneumatic stripping tool

A pneumatic stripping tool, comprising:

• a main base, wherein a top end of the main base is connected with an upper plate through first screws;
• a middle part of a top end of the upper plate is connected with a handle through second screws;
• one end of the upper plate is connected with a pneumatic-wrench fixing seat collar through third screws;
• a mobile cutting assembly is mounted inside the main base;
• the mobile cutting assembly comprises a pneumatic wrench, a power wrench sleeve, a mounting hole, a bottom wheel, two first grooved ball bearings, first snap rings, first mounting slots, two movable bearing seats, second grooved ball bearings, a cutter shaft, two blade spacer bushes, blades, a pipe limiting-block, a limiting shaft, second mounting slots, bearing pin bolts, third grooved ball bearings and bearing washers;
• the pneumatic wrench is connected between the handle and the pneumatic-wrench fixing seat collar;
• an inner side of one end of the pneumatic wrench is connected with the power wrench sleeve;
• the mounting hole is formed in a portion of the main base which is corresponding to the power wrench sleeve;
• an inner side of one end of the power wrench sleeve is connected with the bottom wheel;
• the bottom wheel extends into an inside of the mounting hole;
• portions, which are inside the mounting hole, of outer sides of two ends of the bottom wheel are each sleeved with a corresponding one of the two first grooved ball bearings;
• outer sides of the two first grooved ball bearings are each connected with a corresponding one of the first snap rings;
• the first mounting slots are formed in respective edge parts of the top end of the main base;
• two internal ends of the first mounting slots are each connected with a corresponding one of the two movable bearing seats;
• each of the two movable bearing seats has a respective inner side that is sleeved with a corresponding one of the second grooved ball bearings;
• inner sides of the second grooved ball bearings are sleeved with the cutter shaft;
• portions, which are located between the two second grooved ball bearings, of outer sides of two ends of the cutter shaft are sleeved with the two blade spacer bushes;
• portions, which are located between the two blade spacer bushes, of an outer portion of the cutter shaft are sleeved with the blades;
• an edge part of one end of the main base is provided with the pipe limiting-block through fourth screws;
• an edge part of a top end of the pipe limiting-block is connected with the limiting shaft;
• the limiting shaft penetrates through the pipe limiting-block and extends out an outer side of the pipe limiting-block;
• the second mounting slots are formed in portions, which are above a joint between the main base and the pipe limiting-block, of two ends of the main base;
• each of the second mounting slots has two ends, and each of the two ends of the second mounting slot is connected with a corresponding one of the bearing pin bolts;
• the bearing pin bolts extend into an inside of the main base;
• portions, which are located inside the second mounting slots, of outer portions of the bearing pin bolts are each sleeved with a corresponding one of the third grooved ball bearings;
• and portions, which are located at bottom ends of the third grooved ball bearings, of the outer portions of the bearing pin bolts are each sleeved with a corresponding one of the bearing washers.
