[0024] Specifically, the fixed length component 6 includes a fixed box 61, a pusher 62, a measuring tape 63 and a rotating rod 64. The fixed box 61 is connected to the upper side of the workbench 4. The interior of the fixed box 61 is connected to the rotating rod 64. The outer wall of the rotating rod 64 is connected to the measuring tape 63. One end of the measuring tape 63 is connected to the pusher 62.

[0025] By adopting the above technical solution, the end of the electric MPP tube to be cut is fitted with the pushing piece 62, and then the electric MPP tube is moved onto the two clamping mechanisms 3. The movement of the electric MPP tube drives the pushing piece 62 to move, and the movement of the pushing piece 62 drives the measuring belt 63 to move to protrude from the fixed box 61. The movement of the measuring belt 63 drives the rotating rod 64 to rotate. During the process of pushing the electric MPP tube, the operator can judge the length of the electric MPP tube according to the value at the position of the cutting mechanism 2 on the measuring belt 63, which is convenient for cutting the electric MPP tube to a fixed length.

[0026] Specifically, the push member 62 includes a push plate 621, a push block 622, a slider 623 and a slide groove 624. One end of the measuring tape 63 is connected to the push plate 621, one end of the push plate 621 is connected to the push block 622, and the end of the push block 622 close to the workbench 4 is connected to the slider 623. A slide groove 624 is provided inside the workbench 4 at a position corresponding to the slider 623.

[0027] By adopting the above technical solution, the end of the power MPP tube to be cut is fitted with the push plate 621. When the power MPP tube is subsequently moved, the movement of the power MPP tube drives the push plate 621 to move, and the movement of the push plate 621 drives the push block 622 to move. The movement of the push block 622 drives the slider 623 to move inside the slide groove 624, which makes it convenient for the operator to fix the end of the power MPP tube, and then facilitates the subsequent judgment of the cutting length of the power MPP tube.

[0028] Specifically, the outer wall of the rotating rod 64 and the two ends of the measuring belt 63 are connected to the limit disk 65.

[0029] By adopting the above technical solution, during the movement of the measuring tape 63 , the limiting plate 65 can limit and fix the measuring tape 63 , thereby preventing the measuring tape 63 from being misplaced and ensuring the measurement effect of the measuring tape 63 .

[0030] When this embodiment is used, the end of the electric MPP tube to be cut is fitted with the pushing plate 621, and then the electric MPP tube is moved. The movement of the electric MPP tube drives the pushing plate 621 to move, and the movement of the pushing plate 621 drives the pushing block 622 and the measuring belt 63 to move. The movement of the pushing block 622 drives the slider 623 to move inside the slide groove 624. The measuring belt 63 moves out of the fixing box 61 and drives the rotating rod 64 to rotate. In the process of pushing the electric MPP tube, the operator can judge the length of the electric MPP tube according to the value at the position of the cutting mechanism 2 corresponding to the measuring belt 63, which is convenient for cutting the electric MPP tube to a fixed length. The pressing mechanism 3 is then used to press and fix the electric MPP tube, and then the cutting mechanism 2 is used to cut the electric MPP tube. During the cutting process, the collecting mechanism 5 can collect debris during the cutting process.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the cleaning assembly 7 includes a receiving cavity 72 and a cleaning brush 73. The interior of the fixing plate 1 is provided with the receiving cavity 72, and the interior of the receiving cavity 72 is provided with the cleaning brush 73.

[0033] Specifically, the cleaning assembly 7 further includes a support rod 71, a connecting groove 74 and a connecting spring 75. The side wall of the accommodating cavity 72 is provided with a connecting groove 74, the interior of the connecting groove 74 is plugged with the support rod 71, and a connecting spring 75 is connected between the support rod 71 and the connecting groove 74.

[0034] By adopting the above technical solution, after the cleaning brush 73 is placed inside the accommodating cavity 72, the support rod 71 is loosened, and the connecting spring 75 loses the external force and returns to its original state, driving the support rod 71 to move and protrude from the connecting groove 74. The support rod 71 is used to support the cleaning brush 73 to ensure the stability of the placement of the cleaning brush 73.

[0035] When this embodiment is used, after the cutting of the power MPP tube is completed, when there are debris remaining on the workbench 4, the support rod 71 is moved into the connecting groove 74, and the support rod 71 moves to squeeze the connecting spring 75, and then the cleaning brush 73 is taken out from the accommodating cavity 72, and then the cleaning brush 73 is used to clean the debris remaining on the workbench 4 through the rectangular hole on the workbench 4 into the collection mechanism 5, so that the operator can clean the debris on the workbench 4 and ensure the cleaning and collection effect of the debris.

[0036] The structure and principle of the cutting mechanism 2 composed of a first hydraulic cylinder, a movable plate, a rectangular vertical plate, a motor, a cutting knife, and a positioning rod in the utility model have been disclosed in the environmental protection cutting mechanism of the electric power MPP pipe disclosed in Chinese patent application number 202322466086.4. Its working principle is: a first hydraulic cylinder is provided in the middle part of the top of the fixed plate 1, and the end of the hydraulic rod of the first hydraulic cylinder passes through the top of the fixed plate 1 and is fixedly connected to the movable plate.

A rectangular vertical plate is provided at the bottom of the movable plate, and a motor is provided on the rear side of the rectangular vertical plate through a mounting seat. The end of the motor output shaft passes through the rear side of the rectangular vertical plate and is coaxially connected to the cutting knife. When in use, the motor and the first hydraulic cylinder are started to work. Under the action of the motor, the motor drives the cutting knife to rotate. Under the action of the first hydraulic cylinder, when the first hydraulic cylinder drives the movable plate to move downward, the movable plate drives the rectangular vertical plate, the motor and the cutting knife to move downward synchronously, so that the cutting knife cuts the electric power MPP pipe.

[0039] The working principle and use process of the present invention are as follows: the present invention fits the end of the electric MPP tube to be cut with the pushing plate 621, and then moves the electric MPP tube. The movement of the electric MPP tube drives the pushing plate 621 to move. The movement of the pushing plate 621 drives the pushing block 622 and the measuring tape 63 to move. The movement of the pushing block 622 drives the slider 623 to move inside the slide groove 624. The measuring tape 63 moves out of the fixed box 61 and drives the rotating rod 64 to rotate. In the process of pushing the electric MPP tube, the operator can judge the length of the electric MPP tube according to the value at the position of the corresponding cutting mechanism 2 on the measuring tape 63, which is convenient for cutting the electric MPP tube to a fixed length. The power MPP tube is compressed and fixed by the clamping mechanism 3, and then the power MPP tube is cut by the cutting mechanism 2. During the cutting process, the collecting mechanism 5 can collect debris during the cutting process. After the power MPP tube is cut, when there is debris remaining on the workbench 4, the support rod 71 is moved into the connecting groove 74, and the support rod 71 moves to squeeze the connecting spring 75, and then the cleaning brush 73 is taken out from the accommodating cavity 72, and then the cleaning brush 73 is used to clean the debris remaining on the workbench 4 through the rectangular hole on the workbench 4 into the collecting mechanism 5, which is convenient for the operator to clean the debris on the workbench 4 and ensure the debris cleaning and collection effect.
