[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This highly stable rotary cutter, equipped with a locking block, fixing bolts, a limiting plate, and a mounting box, allows for easy tool installation. When the tool needs to be installed, the operator engages the locking block in the slot, inserts the limiting plate into the limiting slot, and then secures the fixing bolt through the limiting plate to the mounting plate. The motor inside the mounting box is then activated, and its output shaft drives the pulley to rotate. The pulley's rotation, in turn, drives the belt attached to it, which in turn drives the rotating shaft. Since the rotating shaft is connected to the turntable, its rotation causes the turntable to rotate. Because the bottom of the turntable is fixedly equipped with a locking block that engages in a slot on the mounting plate, the rotation of the turntable causes the mounting plate and the tool to rotate synchronously. This facilitates subsequent wire cutting, reduces the workload for operators installing the tool, and saves time and effort.

[0013] This highly stable rotary cutter, equipped with a mounting frame, a fixed frame, an electric telescopic rod, and a base, allows the operator to easily cut the wire. During operation, the operator wraps both ends of the wire to be cut around the fixed shafts installed in the two mounting frames. After tightening, the operator turns on the motor to rotate the cutter. Simultaneously, the operator opens the electric telescopic rod installed on the base and the fixed frame. Because the electric telescopic rod is connected to the mounting frame, it moves the mounting frame and the wire along two sliding rods within a moving groove until they reach the position of the rotating cutter, allowing the cutter to cut the wire. This eliminates the need for the operator to hold the wire during cutting, improving work safety. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a highly stable rotary cutter, including a base 1, a movable groove 6 on the base 1 and a fixed frame 4, two sliding rods 20 fixedly installed in the movable groove 6, a mounting frame 7 slidably installed on the sliding rods 20, and an electric telescopic rod 5 installed on the base 1 and the fixed frame 4. The electric telescopic rod 5 is connected to the mounting frame 7. Because of the electric telescopic rod 5, the mounting frame 7 and the wire can be moved along the two sliding rods 20 in the movable groove 6 until they reach the position of the rotating cutter 15, so that the cutter 15 can cut the wire without the need for the operator to hold the wire for cutting, thus improving the safety of the operation.

[0021] The mounting bracket 7 has a fixed shaft 21 fixedly installed inside, and the mounting plate 14 has a fixed tool 15 fixedly installed inside.

[0022] A mounting box 8 is fixedly installed on the mounting frame 4. A motor 9 is fixedly installed inside the mounting box 8. Because of the motor 9, the grooved wheel 10 can be rotated. The rotation of the grooved wheel 10 drives the belt 11 sleeved on it to rotate. The rotation of the belt 11 drives the rotating shaft 12 to rotate. Since the rotating shaft 12 is connected to the turntable 13, the rotation of the rotating shaft 12 will drive the turntable 13 to rotate. Since the bottom of the turntable 13 is fixedly installed with a locking block 16, and the locking block 16 is engaged in the locking groove 22 opened on the mounting plate 14, the rotation of the turntable 13 will drive the mounting plate 14 and the cutter 15 to rotate synchronously, which facilitates the subsequent cutting of the wire.

[0023] The output shaft of motor 9 is connected to grooved wheel 10. A buffer spring 23 is installed inside column 2 and is connected to support column 3. Because of the installation of buffer spring 23, the parts of fixed tool 15 can be prevented from loosening due to long-term vibration during operation, which would affect the subsequent wire cutting work and improve the stability of the device.

[0024] The base 1 has four columns 2 fixedly installed at its four corners. Support columns 3 are slidably installed on the columns 2. Fixing brackets 4 are fixedly installed on the support columns 3. Two grooved wheels 10 are installed on the fixing brackets 4. Belts 11 are sleeved on the two grooved wheels 10. A rotating shaft 12 is fixedly connected to the bottom of the grooved wheels 10. A turntable 13 is provided at the bottom of the fixing brackets 4. The rotating shaft 12 passes through the fixing brackets 4 and connects to the turntable 13. A locking block 16 is fixedly installed at the bottom of the turntable 13. Because of the locking block 16, when it is necessary to install the tool 15, the worker will engage the locking block 16 in the locking groove 22, then insert the limiting plate 17 into the limiting groove 18, and then fix the fixing bolt 19 through the limiting plate 17 onto the mounting plate 14. This will fix the tool 15, reducing the workload of the worker when installing the tool 15 and saving time and effort.

[0025] A mounting plate 14 is provided below the mounting bracket 4. A slot 22 is provided on the mounting plate 14. A locking block 16 is engaged in the slot 22. A limiting groove 18 is provided on the mounting plate 14 and the locking block 16. A limiting plate 17 is slidably installed in the limiting groove 18. Fixing bolts 19 are installed at both ends of the limiting plate 17. The fixing bolts 19 pass through the limiting plate 17 and are connected to the mounting plate 14.

[0026] The working principle of this utility model is as follows: During operation, the operator wraps both ends of the wire to be cut around the fixed shafts 21 installed in the two mounting brackets 7. After wrapping tightly, the operator engages the locking block 16 in the locking groove 22, then inserts the limiting plate 17 into the limiting groove 18, and then fixes the fixing bolt 19 through the limiting plate 17 onto the mounting plate 14, thus fixing the cutter 15. Then, the motor 9 in the mounting box 8 is turned on. The output shaft of the motor 9 drives the grooved wheel 10 to rotate. The rotation of the grooved wheel 10 drives the belt 11 sleeved on it to rotate. The rotation of the belt 11 drives the rotating shaft 12 to rotate. 12 is connected to turntable 13, so the rotation of the shaft 12 will drive the turntable 13 to rotate. Since the bottom of the turntable 13 is fixed with a mounting block 16, and the mounting block 16 is engaged in the slot 22 opened on the mounting plate 14, the rotation of the turntable 13 will drive the mounting plate 14 and the cutter 15 to rotate synchronously. Then the electric telescopic rod 5 installed on the base 1 and the fixing frame 4 will be opened. Since the electric telescopic rod 5 is connected to the mounting frame 7, the electric telescopic rod 5 will drive the mounting frame 7 and the wire to move along the two slide rods 20 in the moving groove 6 until it moves to the position of the rotating cutter 15, so that the cutter 15 can cut the wire.
