[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 Figures 1-3This utility model provides a cutting device for steel pipes used in tents, including a base plate 4. A support frame 2 is bolted to the top of the base plate 4. A cutting mechanism for cutting the steel pipe is located on the top of the support frame 2. Two fixing plates 11 are bolted to the top of the base plate 4. A rotating shaft is rotatably connected to one side of each fixing plate 11. A take-up / undo roller 12 is bolted to one side of each rotating shaft. A reset mechanism for winding up the take-up / undo roller 12 is located on one side of each fixing plate 11. The two reset mechanisms are torsion springs 10, which are bolted to one side of the fixing plates 11. The other end is fixed to the rotating shaft. The torsion of the torsion spring 10 drives the take-up and release roller 12 to rotate, causing the take-up and release roller 12 to wind up the pull rope 18. At the same time, the pull rope 18 pulls the top plate 9 forward, thereby achieving rapid reset of the top plate 9. The top of the bottom plate 4 is provided with a fixing mechanism to limit the two take-up and release rollers 12. The fixing mechanism consists of multiple guide rods 15. Magnetic blocks 13 are fixed to the outer circumference of each of the multiple guide rods 15 by bolts. The magnetic blocks 13 are attracted to the locking block 16, and the magnetic force of the magnetic blocks 13 quickly fixes the locking block 16. All the guide rods 15 are fixed to the bottom plate 4 by bolts. At the top, two adjacent guide rods 15 are slidably connected to a locking block 16. The bottom of each locking block 16 is fixed with a spring 14 by bolts, and the other end of the spring 14 is fixed to the base plate 4. Multiple slots 17 are provided on the outer circumference of each of the two take-up and release rollers 12, and these slots 17 engage with the locking blocks 16. The spring force of the spring 14 causes the locking blocks 16 to engage with the slots 17, thus quickly fixing the take-up and release rollers 12. Two slide rails 3 are fixed to the top of the base plate 4 by bolts. A top plate 9 is slidably connected to the top of the two slide rails 3. Two pull rods are fixed to one side of the top plate 9 by bolts. The rope 18 is wound around the take-up and release roller 12. The top of the base plate 4 has multiple scale lines 21. The steel pipe is placed on the top of the base plate 4 and then pushed. The steel pipe pushes the top plate 9 to move backward along the slide rail 3. At the same time, the top plate 9 will pull the rope 18 to move. The rope 18 drives the take-up and release roller 12 to rotate. After the steel pipe moves to the appropriate position, the take-up and release roller 12 is fixed by the fixing mechanism. Then, by using the scale lines 21 on the top of the base plate 4 in conjunction with the top plate 9, the size of the steel pipe to be cut can be determined. There is no need for the staff to use a tape measure to measure it, which greatly saves the operation time.

[0023] In this embodiment, the cutting mechanism is a dual-axis cylinder 1. The dual-axis cylinder 1 is fixed to the top of the support frame 2 by bolts. The piston rod of the dual-axis cylinder 1 passes through the support frame 2 and is fixed to a connecting frame 19 by bolts. A motor is fixed to one side of the connecting frame 19 by bolts, and the output shaft of the motor passes through the connecting frame 19 and is fixed to the cutting blade 20 by bolts. A clearance groove 22 is provided on the top of the base plate 4. Two sliding grooves 8 are provided on the top of the base plate 4. The sliding grooves 8 are slidably connected to the clamping plate 6. The sliding grooves 8 allow the clamping plate 6 to slide more smoothly. Two electric motors are fixed to the top of the base plate 4 by bolts. The piston rods of the two electric push rods 5 are fixed to clamping plates 6 by bolts. Each clamping plate 6 has an inclined surface 7 on one side. The steel pipe contacts the inclined surface 7 to prevent the steel pipe from moving upward during cutting, which would affect the cutting process. At the same time, the two electric push rods 5 are activated, which drive the two clamping plates 6 to move towards each other, thereby positioning and clamping the steel pipe. The motor is started, and the output shaft of the motor drives the cutting blade 20 to rotate. Then, the dual-axis cylinder 1 is activated, and the piston rod of the dual-axis cylinder 1 drives the cutting blade 20 to move downward, thereby cutting the steel pipe.

[0024] The working principle and usage process of this utility model are as follows: Place the steel pipe on the top of the base plate 4, then push the steel pipe. The steel pipe pushes the top plate 9 to move backward along the slide rail 3. At the same time, the top plate 9 will pull the pull rope 18 to move. The pull rope 18 drives the take-up and release roller 12 to rotate. After the steel pipe moves to the appropriate position, push the locking block 16 to make the locking block 16 disengage from the magnetic block 13. Through the elastic force of the spring 14, the locking block 16 is locked into the locking groove 17, which fixes the take-up and release roller 12. Then, the scale line 21 on the top of the base plate 4 and the top plate 9 are used to determine the size of the steel pipe to be cut. Then, start the motor. The output shaft of the motor drives the cutting blade 20 to rotate. Finally, start the double-axis cylinder 1. The piston rod of the double-axis cylinder 1 drives the cutting blade 20 to move downward, thereby cutting the steel pipe.

[0025] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
