[0031] Structure description: fixed column 1
[0032] As the basic support component of the whole tool, it plays a role in connecting other key components, and builds a stable architecture for the whole tool, one end of which is connected with handle 2 to facilitate the operator to hold and exert force, and the other end is connected with hollow frame 4 to provide a bearing platform for cutting operation, and the outside is also fixed with fixed plate 12 for fixing some components related to spring clamping.
[0033] Handle 2
[0034] It is designed as a semicircular ring with an internal hollow, which conforms to ergonomics and is convenient for the operator to hold and operate. When using the tool to cut the spring, the operator exerts force by holding the handle 2 to control other components to complete the cutting action, and its connection with the fixed column 1 ensures the stability of force transmission.
[0035] Support 3
[0036] It is connected to the outside of the hollow frame 4 and plays a role in extending the structure. Its main function is to provide support for the arc-shaped clamp 16 connected below, so that the arc-shaped clamp 16 can be in the right position, facilitating the clamping and fixing of the spring. It is an important part to ensure the stability of the spring position during cutting.
[0037] Hollow frame 4
[0038] The hollow frame 4 is the core bearing part of spring placement and cutting operation, and the plurality of holes with different sizes opened on the outer surface thereof can be adapted to springs with different specifications, so that the springs can be placed in appropriate positions to wait for cutting. Meanwhile, the two ends of the hollow frame 4 are respectively rotatably connected with the gear one 5 and the gear two 6, thereby providing a basis for transmission of cutting power, and the hollow frame 4 is further connected with the connecting rod one 7 and the connecting rod two 8, thereby assisting stable movement of the clamping plate one 9 and the clamping plate two 10.
[0039] The gear one 5 and the gear two 6
[0040] The two gears cooperate with each other. When an operator manually rotates one of the gears, for example, the gear one 5, the other gear two 6 is driven to rotate synchronously through meshing transmission between the gears. The two gears serve as a power source for cutting action, and transmit the rotating force applied by the operator on the gear to the clamping plate one 9 and the clamping plate two 10 connected below, thereby driving the cutting knife 11 to perform cutting action.
[0041] The connecting rod one 7 and the connecting rod two 8
[0042] The connecting rod one 7 is connected at one end to the hollow frame 4 and at the other end to the clamping plate two 10, and the connecting rod two 8 is connected at one end to the hollow frame 4 and at the other end to the clamping plate one 9. They assist and stabilize the movement trajectory of the clamping plates. In the process of movement of the clamping plates driven by the gears, the clamping plate one 9 and the clamping plate two 10 are ensured to move stably along the predetermined trajectory, so that the cutting knife 11 can accurately cut the spring, avoiding shaking, deviation and other conditions affecting the cutting effect.

[0044] The clamping plate one 9 and the clamping plate two 10 are respectively rotatably connected at the bottom ends of the gear one 5 and the gear two 6, and each is fixedly connected with the cutting knife 11. Under the driving of the gears, the clamping plate one 9 and the clamping plate two 10 move towards or away from each other, thereby driving the cutting knife 11 to move towards or away from each other, realizing cutting and loosening action of the spring, and being a key component combination directly performing cutting operation.
[0045] The cutting knife 11
[0046] The cutting knife 11 is fixed on the clamping plate one 9 and the clamping plate two 10, and moves with the movement of the clamping plates. When the clamping plates drive the cutting knife 11 to move towards each other, the cutting edge of the cutting knife 11 can cut the spring placed on the hollow frame 4, thereby completing the task of cutting the spring. The sharpness and structural design of the cutting edge will affect the cutting effect and efficiency.
[0047] The fixed plate 12
[0048] Fixed on the fixed column 1, for spring clamp related components provide fixed basis, like spring 13, spring 13, spring 14 respectively connected to the fixed plate 12, through the connecting block 15, connecting block 17 and arc clamp 16 connected, by means of spring elasticity to make arc clamp 16 can realize the clamping and loose action of spring, guarantee the stability of spring in the cutting process.

[0050] They are connected to the fixed plate 12 at one end, and the other end is connected to the arc clamp 16 through the connecting block 17 and the connecting block 15 respectively, and the elasticity of the spring is used to make the arc clamp 16 in a relatively open state when the spring is not placed, which is convenient for the spring to be put in; when the spring is placed, under the action of the spring, the arc clamp 16 will compress the spring 13 and the spring 14, so as to clamp the spring, play an important role in fixing the spring.
[0051] Connecting block 15 and connecting block 17
[0052] Connected to the two ends of the arc clamp 16 respectively, play a role in transition connection, one end is connected to the arc clamp 16, the other end is connected to the spring 14 and the spring 13 respectively, the arc clamp 16 and the spring are connected by elasticity, and the movement of the arc clamp 16 and the spring clamping function are controlled by the elasticity of the spring.
[0053] Arc clamp 16
[0054] Through the support 3 is clamped in the hollow frame 4 below the appropriate position, in the spring 13, spring 14 and other components of the cooperation, on the spring placed in the hollow frame 4 are clamped and fixed, prevent the spring in the cutting process position moves, shakes and other situations, guarantee the cutting operation can be accurate, stable
[0055] Working principle: first, the spring to be cut is placed on the hollow frame 4, and the size of the spring is matched by selecting a suitable hole position on the outer surface of the hollow frame 4, so that the spring can be stably placed, and the arc-shaped clamp 16 plays a role after the spring is placed, the bottom is fixed by the fixed plate 12, one end of the connecting block one 15 and the other end of the connecting block two 17 are connected with the spring two 14 and the spring one 13 respectively, and the arc-shaped clamp 16 can clamp and fix the spring by the elasticity of the spring, so as to prevent the spring from moving during the subsequent cutting process and ensure that the spring is in a stable state during cutting. When the operator manually rotates the gear one 5 or the gear two 6, the power transmission of the cutting action is started, and when the gear one 5 rotates, the clamping plate one 9 connected at the bottom of the gear one 5 rotates and moves correspondingly. Similarly, the gear two 6 rotates and drives the clamping plate two 10 connected thereto to move correspondingly. The clamping plate one 9 and the clamping plate two 10 are respectively fixedly connected with the cutter 11, and the cutter 11 moves synchronously with the clamping plate one 9 and the clamping plate two 10 moving towards or away from each other under the driving of the gears. When they move towards each other, the two cutters 11 can cut the spring fixed on the hollow frame 4, so as to realize the purpose of cutting the spring. In addition, the outer top end of the clamping plate one 9 is rotatably connected with the connecting rod two 8, and the other end of the connecting rod two 8 is rotatably connected with the outer part of the hollow frame 4. The top of the clamping plate two 10 is rotatably connected with the connecting rod one 7, and the end of the connecting rod one 7 away from the clamping plate two 10 is rotatably connected with the outer part of the hollow frame 4. The connecting rod one 7 and the connecting rod two 8 play the role of auxiliary support and stable movement track of the clamping plate one 9 and the clamping plate two 10, so that the cutting action of the cutter 11 is more stable and accurate, and the cutting work can be smoothly and efficiently completed.
