The inner wall of the support plate 601 is slidably connected with a movable plate 602, and a slide groove is provided on the outer wall of the support plate 601. The movable plate 602 is slidably connected to the inner wall of the slide groove. The inner wall of the movable plate 602 is slidably connected with a clamp seat 603, and the clamp seat 603 is arc-shaped. The arc-shaped setting is convenient for clamping metal pipes. The inner wall of the movable plate 602 is elastically connected with a plug-in column 607 through a connecting spring 606. The plug-in column 607 penetrates and It is slidably connected to the inner wall of the left movable plate 602, and the inner side wall of the clamp seat 603 is fixedly connected with a roller 604. The function of the roller 604 is to reduce the friction force. The top of the movable plate 602 is fixedly connected with a connecting rod 605.

The outer wall of the movable plate 602 is provided with a through inclined groove, and the outer wall of the clamp seat 603 contacts the inner wall of the through inclined groove. When the movable plate 602 moves downward, the clamp seat 603 contacts the through inclined groove, thereby driving the clamp seat 603 to move.

[0036] Reference Figure 3-Figure 4One end of the connecting spring 606 is fixedly connected to the outer wall of the plug-in column 607, and the other end of the connecting spring 606 is fixedly connected to the inner wall of the movable plate 602. The outer wall of the plug-in column 607 is slidably connected to the inner wall of the movable plate 602. The elasticity of the connecting spring 606 makes the plug-in column 607 have a reset and limit function. The movable plate 602 is provided with two groups, and the two groups of movable plates 602 are respectively located on the left and right sides of the connecting rod 605. The outer wall of the left movable plate 602 is provided with a plug-in hole 608, and the plug-in hole 608 is provided with multiple groups. The multiple groups are arranged to facilitate the clamp seat 603 to clamp metal pipes of different sizes. The outer wall of the plug-in column 607 is plugged into the inner wall of the plug-in hole 608, and the two are plugged together to prevent the movable plate 602 from moving.

[0037] Reference Figure 5-Figure 6 The movable mechanism 7 includes a support seat 701, the bottom end of the support seat 701 is slidably connected to the top inner wall of the base 1, the top of the support seat 701 is arc-shaped, and the outer wall of the support seat 701 is fixedly connected with a fixing column 706. A slot hole compatible with the fixing column 706 can be opened between the cutting of the metal pipe, and the fixing column 706 is plugged into the slot to prevent the metal pipe from shaking. The right end of the support seat 701 is fixedly connected to the limiting block 703, and the inner wall of the limiting block 703 is elastically connected with a positioning column 705 through a supporting spring 704. The positioning column 705 penetrates and is slidably connected to the inner wall of the limiting block 703, and an inclined surface is set at the bottom end of the positioning column 705, and the inclined surface is set to facilitate the movement of the support seat 701.

[0038] Reference Figure 5-Figure 6 One end of the support spring 704 is fixedly connected to the inner wall of the limit block 703, and the other end of the support spring 704 is fixedly connected to the outer wall of the positioning column 705. The outer wall of the positioning column 705 is slidably connected to the inner wall of the limit block 703. The elasticity of the support spring 704 enables the positioning column 705 to have reset and limit functions. A positioning hole 702 is provided at the top of the base 1, and the bottom end of the positioning column 705 is inserted into the inner wall of the positioning hole 702. There are multiple groups of positioning holes 702, and multiple groups are set to facilitate the use of metal pipes of different lengths.

[0039] Working principle: When relevant personnel need to cut metal pipes, first place the metal pipe on the support seat 701, so that the slotted hole at one end of the metal pipe is aligned with the fixed column 706, and then release the limit of the plug-in column 607, so that the connecting rod 605 drives the two sets of movable plates 602 to move downward, and then the downward movement of the two sets of movable plates 602 will drive the two sets of clamping seats 603 to move closer to the middle, thereby clamping the other end of the metal pipe. When the clamping is completed, the plug-in column 607 is released. At this time, due to the elasticity of the connecting spring 606, the plug-in column 607 is reset and then plugged into the corresponding plug-in hole 608. The operation is simple and convenient, and repeated rotation of the screw rod is avoided to achieve the clamping purpose. After clamping is completed, the hydraulic rod 4 and the cutting knife 5 are started to cut the metal pipe.

[0040] When a section of metal pipe is cut, the support seat 701 is moved so that the support seat 701 drives the metal pipe to move. When the support seat 701 moves, the bottom end slope of the positioning column 705 will contact and squeeze the inner wall of the positioning hole 702, so that the support seat 701 can move. When the support seat 701 moves, the outer wall of the metal pipe will contact the roller 604, and the roller 604 will rotate so that the support seat 701 can drive the metal pipe to move, thereby avoiding the need to release the limit of the clamping seat when the next section of the metal pipe needs to be cut, thereby saving time and effort.
