When it is necessary to process a blade of one size, The end of the corresponding positioning plate 13 is pressed in the direction of the first groove 12. During the sliding process of the positioning plate 13, the inclined surface of the end of the card plate 16 is squeezed and the card plate 16 slides toward the inside of the second groove 15, and then extends into the inside of the first groove 12 again under the elastic force of the first spring 17 and limits the positioning plate 13. At this time, the end of the positioning plate 13 will extend from the side wall of the positioning block 1. After the positioning plates 13 of a pair of positioning blocks 1 are extended, the blade of the corresponding size is placed between the pair of positioning blocks 1, and the end of the blade is blocked by the pair of positioning plates 13, thereby completing the positioning. When the size needs to be changed, the fixing rod 18 can be toggled to drive the card plate 16 to slide, thereby releasing the restriction on the positioning plate 13, and the positioning plate 13 is retracted under the elastic force of the elastic rope 14. Through the above structure, when processing some common size blades, it is convenient to complete the positioning of blades of various common sizes, thereby improving the convenience of the positioning device.

[0023] like Figures 1 to 3As shown, a pair of slide grooves 2 are provided on the top of the positioning block 1; a slide plate 21 is slidably connected to the middle of the pair of slide grooves 2; a plurality of top blocks 22 are fixedly connected to the side of the slide plate 21 facing the fixed rod 18; a connecting belt 23 is fixedly connected between each pair of the fixed rods 18; the top block 22 is arranged toward the middle of the connecting belt 23; a fixing column 24 is fixedly connected to the top of the positioning plate 13; during operation, when it is necessary to adjust the positioning distance of the device, the positioning plate 13 to be used is directly pressed and slid toward the other side of the positioning block 1, and during the sliding process, the fixing column 24 will contact the slide plate 21 and drive the slide plate 21 to slide, thereby driving the top block 22 to squeeze the connecting belt 23, so that the connecting belt 23 pulls a pair of fixed rods 18 and drives a pair of fixed rods 18 are close to each other, thereby driving multiple card plates 16 to release the restriction on the positioning plate 13 inside each first slot 12, so that the positioning plate 13 that is not pressed can be retracted into the first slot 12 under the elastic force of the elastic rope 14, and then the pressure on the positioning plate 13 is released. The positioning plate 13 that needs to be used will be retracted a certain distance due to the pulling force of the elastic rope 14, and at the same time, the fixing column 24 will retreat, and multiple card plates 16 will enter the first slot 12 under the elastic force of the first spring 17, thereby restricting the positioning plate 13 that needs to be used. Through the above structure, when the blade positioning distance needs to be changed, only one positioning plate 13 needs to be directly pressed to simultaneously retract the other positioning plates 13 into the first slot 12, thereby improving the convenience of the device.

[0024] like Figures 1 to 4 As shown, a pressure plate 3 is hinged on the top of one of the positioning blocks 1; a plurality of pressure blocks 31 are slidably connected to the middle of the pressure plate 3; a pair of fixed plates 32 are fixedly connected to the top of another positioning block 1; a spring buckle 33 is slidably connected to the middle of one of the fixed plates 32; during operation, after the blade is placed between the pair of positioning blocks 1, the pressure plate 3 is pressed downward so that the pressure plate 3 extends between the pair of fixed plates 32 and is limited by the spring buckle 33, and at the same time, a pair of pressure blocks 31 will be pressed on top of the blade, making it difficult for the blade to shake during processing, thereby improving the processing accuracy of the blade.

[0025] like Figure 1 to Figure 2 As shown, a screw rod 4 is rotatably connected to the middle part of one of the positioning blocks 1; the other end of the screw rod 4 is threadedly connected to another positioning block 1; a plurality of guide rods 41 are fixedly connected to the side wall of one of the positioning blocks 1; the plurality of guide rods 41 are slidingly matched with the middle part of another positioning block 1; during operation, when it is necessary to adjust the distance between a pair of positioning blocks 1 according to the size of the blade, it is only necessary to rotate the screw rod 4 to expand or reduce the distance between the pair of positioning blocks 1. At the same time, the arrangement of the screw rod 4 and the guide rod 41 can improve the overall stability of the entire device, thereby improving the processing accuracy when processing the blade.

[0026] like Figures 1 to 4As shown, a second spring 5 is fixedly connected to the top of the positioning block 1; the second spring 5 is located between a pair of fixed plates 32; a top plate 51 is fixedly connected to the top of the second spring 5; during operation, after the pressing plate 3 is pressed down, the pressing plate 3 will squeeze the top plate 51 to shrink the second spring 5.

[0029] During operation, the distances between the plurality of positioning plates 13 are set according to the commonly used sizes of the processing blades, and then a pair of positioning blocks 1 are placed opposite to each other. When it is necessary to process a blade of one size, the end of the corresponding positioning plate 13 is pressed toward the direction of the first groove 12. During the sliding process of the positioning plate 13, the inclined surface of the end of the clamping plate 16 is squeezed and the clamping plate 16 slides toward the inside of the second groove 15, and then the clamping plate 16 is extended into the inside of the first groove 12 again under the elastic force of the first spring 17 and the positioning plate 13 is limited. At this time, the end of the positioning plate 13 extends out from the side wall of the positioning block 1. After the positioning plates 13 of a pair of positioning blocks 1 are extended, A blade of corresponding size is placed between a pair of positioning blocks 1, and the end of the blade is blocked by a pair of positioning plates 13 to complete the positioning. When the size needs to be changed, the fixing rod 18 can be toggled to drive the card plate 16 to slide, thereby releasing the restriction on the positioning plate 13, so that the positioning plate 13 is retracted under the elastic force of the elastic rope 14. When the positioning distance of the device needs to be adjusted, the positioning plate 13 to be used is directly pressed and slid toward the other side of the positioning block 1.

After the blade is placed between the pair of positioning blocks 1, the pressure plate 3 Pressing downward, the pressing plate 3 extends into between a pair of fixed plates 32 and is limited by the spring catch 33. At the same time, a pair of pressing blocks 31 will be pressed on top of the blade, making it difficult for the blade to shake during processing. When it is necessary to adjust the distance between a pair of positioning blocks 1 according to the size of the blade, it is only necessary to rotate the screw 4 to expand or reduce the distance between the pair of positioning blocks 1. At the same time, the setting of the screw 4 and the guide rod 41 can improve the overall stability of the entire device. After the pressing plate 3 is pressed down, the pressing plate 3 will squeeze the top plate 51 to shrink the second spring 5. After the processing is completed, the restriction on the pressing plate 3 is released. At this time, the pressing plate 3 will be directly bounced open by the second spring 5, thereby reducing the number of operating steps.
