[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0031] Example

[0032] See also Figure 1-Figure 6 A buffer reset mechanism for a cutting machine includes a base 1, a cutting machine body 2 is arranged on the top of the base 1, a fixed rod 4 and a rotating rod 5 are installed in the middle of the base 1, and two groups of reset components 6 are provided. The reset component 6 includes a connecting plate 61, a pushing member 65 and a rotating member 67 are arranged on one side of the connecting plate 61, a buffer component 7 is arranged on one side of the reset component 6, and a driving component 3. The driving component 3 includes a transmission member 35 and a toothed belt 36.

[0033] Preferably, the drive assembly 3 includes a placement member 31, an arc-shaped hole 32 is provided on one side of the placement member 31, the drive assembly 3 passes through the interior of the drive member 34, a housing 33 is installed on one side of the placement member 31, a transmission member 35 is installed inside the placement member 31, one end of the transmission member 35 is connected to the cutting machine body 2, a drive member 34 is installed at the top of the placement member 31, the drive member 34 is specifically a motor, and the output end of the drive member 34 is connected to the transmission member 35 through a toothed belt 36. The design of the drive assembly 3 at the top of the device cleverly disperses the weight of the cutting machine body 2 and the drive member 34, and places them on both sides of the top of the connecting plate 61. Such a layout can effectively reduce the inclination of the force on both sides of the connecting plate 61 when the cutting machine body 2 is rotated for practical operation, so that the tension spring 75 maintains a normal stretched state, further reducing the tension on the cutting machine body 2 when it is stably placed, thereby significantly improving the service life of the tension spring 75.

[0034] Preferably, the reset assembly 6 includes two fixed plates 62, which are connected to both sides of the top of the connecting plate 61, the top of the fixed plate 62 is connected to the bottom of the placement member 31, and a special-shaped plate 63 is provided on one side of the connecting plate 61. The special-shaped plate 63 is fixedly connected to the base 1 through a long plate 68. The rotating rod 5 movably penetrates the special-shaped plate 63, and a round rod 64 is fixedly connected to one side of the special-shaped plate 63. The middle part of the round rod 64 movably penetrates the middle part of the pusher 65. One end of the pusher 65 is connected to a push plate 66, and the outer wall of the push plate 66 is slidably connected to the inner wall of the rotating member 67. The rotating rod 5 is fixedly penetrated through the middle part of the connecting plate 61 and the rotating member 67 in sequence. When the cutting machine body 2 is pressed down and driven to rotate to cut parts, the connecting plate 61 rotates and tilts forward accordingly. Since the rotating rod 5 is fixedly connected to the connecting plate 61, the rotating rod 5 also rotates synchronously. At the same time, the rotating member 67 fixed in the middle part of the rotating rod 5 also rotates accordingly. During the rotation of the rotating member 67, its inner corner portion squeezes the push plate 66, causing the push plate 66 to move downward, thereby triggering the push member 65 connected to the push plate 66 to rotate, and its other end tilts outward. As the push member 65 rotates, the short rod 71 moves to the side away from the long plate 68, causing the tension spring 75 to be stretched. Once the cutting machine body 2 completes the cutting and releases the external force, the tension spring 75 will use its internal elastic force to begin to shrink back to the original position, thereby driving the push member 65 to rotate, and further pushing the rotating member 67, the rotating rod 5 and the connecting plate 61 to return to the initial position. This series of actions effectively realizes the buffer reset function of the device and ensures the stability and reliability of the device.

[0035] In addition, when the cutting machine body 2 completes its work and releases the external force, the tension spring 75 begins to shrink to its original position by virtue of its own elastic force, driving the pushing member 65 to rotate, and further pushing the rotating member 67, the rotating rod 5 and the connecting plate 61 to rotate to the initial position, thereby realizing the buffer reset mechanism of the entire device.

[0036] It is worth mentioning that if the tension spring 75 needs to be replaced or maintained, it can be easily removed from the inside of the threaded groove 73 by rotating the threaded rod 74, so that both ends of the tension spring 75 are exposed to the outside, making it easy to remove from the surface of the device and replace it.

[0037] Preferably, the buffer assembly 7 includes a short rod 71, a long rod 72 is provided on one side of the short rod 71, one end of the short rod 71 is fixedly connected to one side of the pusher 65, one end of the long rod 72 is fixedly connected to the special-shaped plate 63, one end of the short rod 71 and the long rod 72 are both provided with a threaded groove 73, the internal thread of the threaded groove 73 is connected to a threaded rod 74, and a tension spring 75 is connected between the short rod 71 and the long rod 72.

[0038] The use process of a buffer reset mechanism of a cutting machine provided by the present invention is as follows: the cutting machine body 2 is pressed down to drive the cutting machine body 2 to rotate to cut the parts. At this time, the connecting plate 61 rotates and tilts forward. The rotating rod 5 and the connecting plate 61 are fixedly connected, so the rotating rod 5 rotates, and the rotating member 67 is also fixed to the middle part of the rotating rod 5, so the rotating member 67 rotates at the same time. When the rotating member 67 rotates, the inner angle squeezes the push plate 66, pushing the push plate 66 downward, so that the pushing member 65 connected to the push plate 66 rotates, and the other end of the pushing member 65 tilts outward, and the short rod 71 moves to the side away from the long plate 68, and the tension spring 75 is stretched. Therefore, after the cutting machine body 2 is used, the cutting machine body 2 is no longer pulled by external force. The tension spring 75 has an elastic force that contracts to the original position, drives the pushing member 65 to rotate, and pushes the rotating member 67 to rotate, so that the rotating rod 5 and the connecting plate 61 rotate and return to the original position, thereby completing the buffer reset of the device. At the same time, by rotating the threaded rod 74, the threaded rod 74 can be taken out from the inside of the thread groove 73, so that the two ends of the tension spring 75 are exposed, and the tension spring 75 can be smoothly removed from the surface of the device for replacement. The driving assembly 3 arranged at the top disperses the weight of the cutter body 2 and the driving member 34, so that the cutter body 2 and the driving member 34 are placed on both sides of the top of the connecting plate 61. In this way, when the cutter body 2 is rotated, the inclination of the force on both sides of the connecting plate 61 will be reduced, and the tension spring 75 maintains a normal stretched state, so that the tension force on the cutter body 2 when it is stably placed is smaller, which is more helpful to increase the practical life of the tension spring 75.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
