The second clamping plate 312 is located above the limiting seat 304.

[0027] It needs to be further explained that: when the muffle tube needs to be fixed, the rotating shaft 306 at both ends is manually adjusted so that the rotating rod 313 at the top of the rotating shaft 306 can be displaced and slid inward, and the first clamping plate 307 is moved close to the outer wall of the muffle tube.

[0031] What needs to be further explained is that: under the drive of the driving motor 401, the driving screw 408 at the output end can be driven to achieve relative rotation, and then the positioning block 409 on the driving screw 408 can be driven to slide.

At the same time, in conjunction with the cutting motor 406, the cutter 407 can be used to realize the cutting process, which greatly improves the cutting accuracy and stability.

[0032] The technical solution provided by the present invention is that when it is necessary to achieve stable clamping and cutting of the muffle tube, the muffle tube is placed on a set of limit clamping mechanisms 3, and the displacement and fixation of the limit clamping mechanisms 3 can be achieved by manually adjusting the driving mechanism 2, and then the cutting process is completed by the sliding cutting mechanism 4.

[0033] Next, the muffle tube is placed on a set of limit seats 304, and a force is applied to rotate the rotating shaft 306, so as to slide the rotating rod 313 inward or outward. The first clamping plate 307 connected to the top of the rotating rod 313 can clamp and fix it, and the first spring 315 is used to achieve buffering and limiting.
