[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Embodiment one, please refer to Figures 1-4 The utility model provides a kind of urban gas handheld pipe cutting device, including frame body 1, the frame body 1 top is provided with threaded rod 2, one end of the threaded rod 2 is inserted into the frame body 1 by penetrating the top of the frame body 1, the threaded rod 2 one end is connected with pressure device, cutting device is provided below the pressure device, and the cutting device is installed in the frame body 1 inner bottom, pipe is clamped and fixed between pressure device and cutting device by moving pressure device downwards, pipe is fixed by rotating frame body 1 to pipe cutting;

[0025] The other end of the threaded rod 2 connected with handle 3 outside the frame body 1;

[0026] The pressure device includes sliding block 4, one end of the threaded rod 2 is connected with the sliding block 4,

[0027] The bottom end of the sliding block 4 away from threaded rod 2 is provided with two rollers 6, the bottom end of the sliding block 4 is rotatably connected with the roller 6 by fixed pin 5, for moving downward by rotating threaded rod 2 to drive roller 6 to clamp and fix pipe between two rollers 6 and cutting knife 9;

[0028] The frame 1 has a "[" shaped structure. Vertically arranged limiting strips 7 are provided on the two side walls of the frame 1 away from the opening. A groove is provided on one side of the sliding block 4. Limiting grooves that cooperate with the limiting strips 7 are provided on both sides of the groove. One side of the sliding block 4 cooperates with the limiting strips at one end of the frame 1 through the limiting grooves, so that the sliding block 4 can move along the limiting strips 7.

[0029] The cutting device is a disc-shaped cutting blade 9, which is located below the two rollers 6. The pipe is clamped and fixed between the two rollers 6 and the cutting blade 9 by moving the threaded rod 2 to drive the rollers 6 to move.

[0030] An opening 8 is provided at the bottom of the frame 1, and the cutting blade 9 is located inside the opening 8. The cutting blade 9 is rotatably mounted at the bottom of the frame 1 via a detachable device.

[0031] The detachable device includes a pin 16, the cutting blade 9 has a disc-shaped structure, and the pin 16 passes through the center of the cutting blade 9 and connects to the bottom of the inner end of the frame 1.

[0032] It is worth noting that by setting up a frame 1, a threaded rod 2, a handle 3, a sliding block 4, a fixing pin 5, a roller 6, a limit strip 7, an opening 8, and a cutting blade 9, rotating the handle causes the threaded rod to rotate inside the frame, pushing the sliding block to slide on the limit strip, thereby bringing the roller closer to the cutting blade 9 and fixing the pipe. Then, rotating the frame allows for fast and accurate cutting of the pipe. The cutting blade 9 is made of stainless steel.

[0033] In this embodiment, the handle 3 is held and rotated, causing the threaded rod 2, which is fixedly connected to it, to rotate within the frame 1. As the threaded rod 2 rotates, the sliding block 4, which is fixedly connected to its bottom end, begins to move. Due to the restriction of the limiting strip 7, the sliding block 4 can only slide on the limiting strip 7, thus ensuring the stability and directionality of its movement. The movement of the sliding block 4 causes the roller 6 to move closer to or away from the cutting blade 9. When the roller 6 moves closer to the cutting blade 9, they work together on the pipe to clamp and fix it. At this time, the operator continues to rotate the handle 3 so that the cutting blade 9 can cut the pipe. The design of the opening 8 allows the cutting blade 9 to act accurately on the pipe, ensuring the accuracy and efficiency of the cutting.

[0034] Example 2, as Figure 1 - Figure 4 As shown, the detachable device also includes a sliding rod 11;

[0035] like Figure 4As shown, the frame 1 is provided with a sliding groove 10 at the bottom end of the frame 1 towards the opening end side of the frame 1, the sliding rod 11 is a T-shaped rod, the sliding groove 10 is a T-shaped groove, one end of the sliding rod 11 located in the sliding groove 10 is connected with a limiting ring 12, and a spring is sleeved on the side wall of one end of the sliding rod 11, the other end of the sliding rod 11 located outside the sliding groove 10 is connected with one end of the bolt 16 through a connecting rod 15, the other end of the sliding rod 11 is provided with a pull ring 14, and the pull ring 14 is located in front of the connecting rod 15; by pulling the pull ring 14, the pull ring 14 slides with the sliding rod 11 in the sliding groove 10, the sliding rod 11 moves with the limiting ring 12, and the spring 13 is compressed, at the same time, the pull ring 14 moves with the connecting rod 15, the connecting rod 15 moves with the bolt 16, so that the bolt 16 is separated from the cutting knife 9, and the cutting knife 9 can be easily taken out for replacement or maintenance.

[0036] The working principle and use process of the utility model are as follows: the operator holds the handle 3 and rotates, the handle 3 drives the threaded rod 2 fixedly connected therewith to rotate in the frame 1, along with the rotation of the threaded rod 2, the sliding block 4 fixedly connected with the bottom end thereof starts to move, due to the limitation of the limiting strip 7, the sliding block 4 can only slide on the limiting strip 7, thereby ensuring the stability and directionality of the movement thereof, the movement of the sliding block 4 drives the rollers 6 to approach or move away from the cutting knife 9. When the rollers 6 approach the cutting knife 9, they jointly act on the pipeline, realizing the clamping and fixing of the pipeline; at this time, the operator can continue to rotate the handle 3, so that the cutting knife 9 cuts the pipeline, the design of the opening 8 enables the cutting knife 9 to accurately act on the pipeline, ensuring the accuracy and efficiency of the cutting. When operating, the pull ring 14 slides with the sliding rod 11 in the interior of the frame 1, the sliding rod 11 moves with the limiting ring 12, and the spring 13 is compressed, at the same time, the pull ring 14 moves with the connecting rod 15, the connecting rod 15 moves with the bolt 16, so that the bolt 16 is separated from the cutting knife 9, and the cutting knife 9 can be easily taken out for replacement or maintenance.

[0037] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
