[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 A portable boring machine includes a boring bar head 1, a boring bar connecting seat 2, a boring bar 3, a transmission sleeve 4, a flange fixing seat 5, a fixing sleeve 6, and a transverse feed assembly. One end of the flange fixing seat 5 is connected to the fixing sleeve 6. The transmission sleeve 4 is housed inside the fixing sleeve 6, and bearings 14 are installed between the two ends of the inner wall of the transmission sleeve 4 and the boring bar 3. The bearings 14 reduce friction. The boring bar 3 is housed inside the transmission sleeve 4, and one end of the boring bar 3 is connected to the boring bar connecting seat 2. The boring bar connecting seat 2 is connected to the boring bar head 1. The boring bar head 1 and the boring bar connecting seat 2 are connected by a second screw. A drive connection bayonet 15 is provided at the end of the boring bar 3 facing away from the boring bar connecting seat 2. The drive connection bayonet 15 is for easy connection of a motor drive for the boring machine to rotate and bore. The flange fixing seat 5 has slots on all four sides for easy position adjustment and better fixation.

[0023] Specifically, the boring tool head 1 and the tool head connecting seat 2 are connected by a second screw, which is used to lock the tool head in place. When the tool head needs to be replaced, the screw is loosened and the tool head is replaced.

[0024] Specifically, the lateral feed assembly is located on the outer wall of the fixed sleeve 6, passing through the fixed sleeve 6 and connecting to the transmission sleeve 4. The lateral feed assembly includes a lateral feed handwheel 7, which is rotatably connected to the outer wall of the fixed sleeve 6. An annular limiting groove 11 is formed on the inner wall of the lateral feed handwheel 7. A keyway 8 is formed on the outer wall of the transmission sleeve 4, and a connecting key 9 is connected to the keyway 8. The connecting key 9 is connected to the bottom surface of the keyway 8 by a first screw. A through groove 10 is formed on the outer wall of the fixed sleeve 6, and the other end of the connecting key 9 passes through the through groove 10 and connects to the annular limiting groove 11. The connecting key 9 is L-shaped. An external thread 12 is formed on the outer wall of the fixed sleeve 6, and an internal thread 13 is formed on the inner wall of the lateral feed handwheel 7. The lateral feed handwheel 7 is threadedly connected to the fixed sleeve 6.

[0025] During operation, the flange mounting base 5 is fixed in the corresponding position, and the drive motor is connected through the drive connection bayonet 15. The drive motor rotates, which drives the boring bar 3 to rotate. The rotation of the boring bar 3 drives the tool head connecting seat 2 and the boring tool head 1 to rotate and bore. The transverse feed handwheel 7 is rotated, and the transverse feed handwheel 7 moves on the outer wall of the fixed sleeve 6. The connecting key 9 pushes the transmission sleeve 4 and the boring bar 3 inside the transmission sleeve 4 to move forward, which in turn drives the tool head connecting seat 2 and the boring tool head 1 to move forward, thereby realizing transverse movement boring.

[0026] This portable boring machine features a flange mounting base connected to a fixed sleeve at one end. Inside the fixed sleeve is a transmission sleeve, and inside the transmission sleeve is a boring bar. One end of the boring bar is connected to a tool head connector, which in turn connects to the boring tool head. A transverse feed assembly is located on the outer wall of the fixed sleeve, penetrating the fixed sleeve and connecting to the transmission sleeve. The machine boasts a simple structure, easy installation and disassembly, and convenient maintenance; it is also convenient for travelers to carry.
