Based on the embodiments in 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.

[0020] See also Figure 1-3 A new type of pipe cutting equipment includes a main bracket 1, a handheld cutter 2 is installed on one side of the main bracket 1, and a pipe clamping assembly is installed on the other side. The pipe clamping assembly completes the clamping work of the pipe. The handheld cutter 2 includes an outer shell 3, and an axial hole is provided on the outer shell 3 and the main bracket 1. A positioning pin 4 is installed in the axial hole. The handheld cutter 2 can rotate around the positioning pin 4, and the pipe is cut by a blade 5 in the handheld cutter 2. A baffle 26 is also provided on the outer shell 3. The guard plate 26 can protect the flying plastic debris when the blade 5 cuts the pipe, thereby improving the safety of construction.

[0021] An arc-shaped groove portion 6, a limiting hole 7 and a locking hole 8 are provided on the main bracket 1, and a self-locking spring pin 9 is installed on the outer shell 3. The protruding portion of the self-locking spring pin 9 can cooperate with the limiting hole 7 and the locking hole 8 respectively. The function of the self-locking spring pin 9 is that the user can manually pull up the self-locking spring pin 9 so that the protruding portion of the self-locking spring pin 9 leaves the limiting hole 7 or the locking hole 8.

[0022] A movable block 10 is fixedly installed on the outer shell 3, and the head end of the movable block 10 extends into the arc-shaped groove portion 6, and a hexagon socket head screw 11 is installed on the head end of the movable block 10, and the screw head of the hexagon socket head screw 11 faces the axial hole, and a bending cover 12 is installed on the main bracket 1, and the bending cover 12 covers the movement path of the hexagon socket head screw 11 in the arc-shaped groove portion 6. A screw hole is provided on the head end of the movable block 10, and the hexagon socket head screw 11 is threadedly connected to the screw hole, so the head end of the movable block 10 and the hexagon socket head screw 11 slide together in the arc-shaped groove portion 6, the hexagon socket head screw 11 and the bending cover 12 are made of metal, and metal material has better strength than plastic, the screw head of the hexagon socket head screw 11 contacts the inner wall of the bending cover 12, if wear occurs, the hexagon socket head screw 11 and the bending cover 12 can be replaced.

[0023] When the protruding portion of the self-locking spring pin 9 is located in the locking hole 8, the movable block 10 is located at the front end of the arc-shaped groove portion 6, and the handheld cutting machine 2 is in an open state. When the protruding portion of the self-locking spring pin 9 is located in the limiting hole 7, the movable block 10 is located at the rear end of the arc-shaped groove portion 6, and the handheld cutting machine 2 is in a working state.

[0024] When cutting the pipe, it is also necessary to ensure that the pipe is fixed. The pipe clamping assembly includes an upper seat 13 and a lower seat 14 arranged on the main bracket 1. Bearings 15 are arranged in the through holes of the upper seat 13 and the lower seat 14. An adjusting screw 16 is arranged in the two bearings 15. The adjusting screw 16 passes through the extension section outside the upper seat 13 and is equipped with a hand wheel 17. The user can turn the hand wheel 17, and the bearings 15 of the upper seat 13 and the lower seat 14 are connected to the adjusting screw 16, so the adjusting screw 16 can rotate.

[0025] A sliding bracket 18 is provided on the adjusting screw 16, and the sliding bracket 18 is between the upper seat 13 and the lower seat 14. A nut 19 is provided in the through hole of the sliding bracket 18, and the nut 19 is threadedly connected to the adjusting screw 16, and a limiting pressure cover 20 is provided on the nut 19 and the bearing 15. The purpose of the limiting pressure cover 20 is to ensure that the position of the nut 19 and the bearing 15 is stable and does not deviate. After the user turns the hand wheel 17, the adjusting screw 16 rotates, and the nut 19 acts to make the sliding bracket 18 move up and down on the adjusting screw 16.

[0026] Both sides of the sliding bracket 18 are respectively connected to one end of the movable arm 21 through a movable connection method, and a large roller 22 is installed on the other end of the movable arm 21 through a movable connection method. The two movable arms 21 are connected to one end of the connecting piece 23 through a movable connection method, and the other end of the connecting piece 23 is connected to the lower seat 14 through a movable connection method. Small rollers 24 are installed on both sides of the lower seat 14 through a movable connection method. The movable connection method adopts a round shaft and shaft clamps at both ends of the round shaft. The movable arm 21, the large roller 22, the connecting piece 23, and the small roller 24 are installed on the round shaft, so they can be rotated around the round shaft. The structure has two large rollers 22 and small rollers 24, which can act on four directions of the pipe to ensure the stability of the pipe clamping.

[0027] The movable arms 21 at both locations are provided with detachable handles 25. The purpose of the handles 25 is to allow the user to hold them and rotate the entire device around the pipe. Only when the pipe is long and it is not suitable for rotating the pipe, an auxiliary handle 25 must be installed to allow the machine to rotate 360 ​​degrees while the pipe remains stationary. If the pipe is simply rotated for cutting, the handle 25 may not be installed.

[0028] Working principle: Place the device on the pipe so that the pipe is located between the two movable arms 21. The user turns the hand wheel 17 to rotate the adjusting screw 16, and the adjusting screw 16 drives the sliding bracket 18 to rise. Then the two movable arms 21 gradually move closer until the hand wheel 17 can no longer rotate further. At this time, the two large rollers 22 and the small rollers 24 act on the four directions of the pipe to fix it. After the pipe is fixed, pull up the self-locking spring pin 9, and then move the handheld cutting machine 2 downward to make the protruding part of the self-locking spring pin 9 leave the locking hole 8. By releasing the self-locking spring pin 9, the user can start the handheld cutter 2 to cut the pipe. The head end of the movable block 10 slides in the arc-shaped groove 6 until the self-locking spring pin 9 moves to the limiting hole 7, and the protrusion of the self-locking spring pin 9 is inserted into the limiting hole 7. At this time, the handheld cutter 2 cannot move downward. This state means that the blade 5 in the handheld cutter 2 has cut into the inner wall of the pipe. Then the user releases the handheld cutter 2, holds a handle 25 in one hand, and then rotates the entire device around the pipe until the pipe is cut.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
