The operator releases the foot switch 6, the telescopic mechanism 3 contracts, and the cutter 4 moves in the opposite direction to return to the initial position, which saves time and effort, can reduce the requirement for the operator's arm strength, and avoids the problem of arm pain of the operator.

[0047] Embodiment 2 is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: Figure 3 and Figure 4As shown, it also includes a pressing plate 13, which is slidably arranged above the operating table 2, and the sliding direction of the pressing plate 13 is the same as the length direction of the longitudinal groove 9-2, and the tube body 18 to be cut is used to be placed between the pressing plate 13 and the operating table 2. The length direction of the longitudinal groove 9-2 is set along the front-to-back direction, and the pressing plate 13 can slide along the front-to-back direction. When the tube body 18 to be cut needs to be placed in the tube body placement groove 9, the pressing plate 13 is slid to the front end of the operating table 2. After placement, it is ensured that the pressing plate 13 can press the parts of the tube body 18 to be cut located on both sides of the cutter 4. The pressing plate 13 cooperates with the operating table 2 to clamp the tube body 18 to be cut, which can prevent the tube body 18 to be cut from moving upward during the cutting process and affecting the cutting effect. When the front and rear positions of the left and right cutters 4 are different, the pressing plate 13 includes a front transverse plate, a rear transverse plate and a longitudinal plate, the front transverse plate is used to cooperate with the cutter 4 located on the front side, the rear transverse plate is used to cooperate with the cutter 4 on the rear side, and the longitudinal plate is connected between the front transverse plate and the rear transverse plate.

[0048] Furthermore, if Figure 3 , Figure 4 and Figure 5 As shown, it also includes a waste pushing plate 14, a slot 15 is opened on the pressure plate 13, the lower end of the waste pushing plate 14 is plugged into the slot 15, and the upper end of the waste pushing plate 14 is located above the pressure plate 13. The waste pushing plate 14 separates the cut waste from the longitudinal groove 9-2 by sliding the pressure plate 13. The front end of the longitudinal groove 9-2 is an open end. Before cutting, the waste pushing plate 14 is located behind the cutter 4, so that the waste pushing plate 14 is placed on the tube body 18 to be cut. After cutting is completed, the cutter 4 drops back to the initial position, and the pressure plate 13 is slid forward to take out the resulting product located behind the cutter 4. When the waste pushing plate 14 moves to the top of the cutter 4, the waste pushing plate 14 drops along the slot 15, and the lower end of the waste pushing plate 14 drops into the longitudinal groove 9-2 and contacts with the cut waste. Continue to slide the pressure plate 13 forward, then the waste pushing plate 14 pushes the waste forward, so that the waste is separated from the longitudinal groove 9-2, and then the next tube body 18 to be cut is placed in the tube body placement groove 9, so as to facilitate the discharge of the waste.

[0049] Furthermore, if Figure 3 and Figure 4 As shown, it also includes a dovetail bar 16, which is arranged on the lower end faces of both ends of the pressing plate 13, and a dovetail groove 17 is provided on the upper end face of the operating table 2, the length direction of the dovetail groove 17 is the same as the length direction of the longitudinal groove 9-2, one end of the dovetail groove 17 is an open end, and the other end is a closed end, and the dovetail bar 16 is plugged into the longitudinal groove 9-2 to form a sliding fit. Two left and right dovetail grooves 17 are provided on the upper end face of the operating table 2, and the length direction of the dovetail groove 17 is arranged along the front-back direction. The cooperation between the dovetail bar 16 and the dovetail groove 17 can play a guiding and limiting role for the pressing plate 13, preventing the pressing plate 13 from shaking up and down and left and right during the sliding process, and having better stability.

[0050] Furthermore, if Figure 3 As shown, one end of the dovetail groove 17 near the transverse groove 9-1 is an open end, and the other end is a closed end. The rear end of the dovetail groove 17 is an open end, and the front end is a closed end, which can prevent the dovetail strip 16 from slipping out of the dovetail groove 17 when the pressure plate 13 drives the waste pushing plate 14 to move forward to discharge the waste, and the safety is better.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
