By inserting the connecting tube 16 into the inside of the positioning tube 15, and then fastening the positioning tube 15 and the connecting tube 16 by bolts on the surface of the positioning tube 15, the blade body 17 is stably installed at one end of the connecting tube 16, and then the positioning tube 15 is inserted into the inside of the installation tube 11, and during the insertion process, the position of the first rack plate 13 is always adapted to the position of the second gear 20. Therefore, when the connecting tube 16 is installed as a whole, after the connecting tube 16 is clamped, the control panel 2 is designed to start The oil cylinder 14 is driven to move the first rack plate 13 upward through the oil cylinder 14, and the second gear 20 is driven to rotate during the movement, so that the second gear 20 will drive the first gear 19 to rotate. When the first gear 19 rotates, it can also drive the second rack plate 21 to move upward as a whole, so that the second rack plate 21 drives the first spring seat 23 and the top column 25 to move upward inside the mounting groove, so that the first clamping ring 26 can contact the inner side wall of the positioning cylinder 15. After the first clamping ring 26 contacts the inner side wall of the positioning cylinder 15, the extrusion spring 24 and the top column 25 begin to contract, thereby strengthening the elastic force and improving the stability. Similarly, the third rack plate 27 begins to descend, so that the second clamping ring 29 will contact the inner side wall of the positioning cylinder 15 The bottom wall improves the stable connection between the internal structure of the connecting cylinder 16 and the inner wall of the positioning cylinder 15, improves the clamping effect to a certain extent, and solves the problem of poor fastening of bolts used in the past.

After rotating to the adjusted angle, the oil cylinder 14 is opened again to clamp the positioning cylinder 15 and the connecting cylinder 16. When the first rack plate 13 begins to rise, the second rack plate 21 begins to rise, and the third rack plate 27 begins to descend, so that the third rack plate 27 will drive the first connecting ring 30 and the first pull rope 31 to descend as a whole, and then the first pull rope 31 can be limited to a certain position by the limiting roller 32, so that the first pull rope 31 is clamped by the first The connecting ring 30 is pulled downward stably. After the first pull rope 31 is pulled, the fixed column 34 can be pulled to move leftward inside the slide groove, so that the slider 35 and the limit frame 36 can be moved leftward uniformly, so that the second stretch 37 will also move leftward to a certain extent, and then the second stretch 37 is sleeved inside the sleeve 48 to limit the second stretch 37 to a certain extent, and then the second stretch 37 can pull the second connecting ring 45 and the connecting spring 44 to move leftward to a certain extent, so that the third connecting ring 46 will pull the second contact plate 47 to move leftward to a certain extent, and the two groups of piston cylinders 41 can provide a certain stability for the leftward movement of the second contact plate 47, and at the same time, the limit plate 42 and the limit ring 43 are used to prevent the connecting spring 44 from bending during the leftward movement.Therefore, the second abutment plate 47 will fit the cutting edge of the blade body 17, and the cutting edge of the blade body 17 is clamped to a certain extent by the first abutment plate 39 and the second abutment plate 47, thereby further improving the clamping effect of the blade body 17.

[0033] Working principle: When the staff uses the device, firstly, the device is connected to an external power supply to provide power support for the device. When in use, firstly, the connecting tube 16 is inserted into the interior of the positioning tube 15, and then the positioning tube 15 and the connecting tube 16 are fastened by the bolts on the surface of the positioning tube 15. The blade body 17 is stably installed at one end of the connecting tube 16, and then the positioning tube 15 is inserted into the interior of the installation tube 11, and during the insertion process, the position of the first rack plate 13 is always matched with the position of the second gear 20. Therefore, when the connecting tube 16 is installed as a whole, after the connecting tube 16 is clamped, the oil cylinder 14 is started through the design of the control panel 2, and the first rack plate 13 is driven by the oil cylinder 14 to move upward, and the operation During the movement, the second gear 20 is driven to rotate, so that the second gear 20 will drive the first gear 19 to rotate. When the first gear 19 rotates, it can also drive the second rack plate 21 to move upward as a whole, so that the second rack plate 21 drives the first spring seat 23 and the top column 25 to move upward inside the mounting groove, so that the first clamping ring 26 can contact the inner side wall of the positioning tube 15. After the first clamping ring 26 contacts the inner side wall of the positioning tube 15, the extrusion spring 24 and the top column 25 begin to contract, thereby strengthening the elastic force and improving the stability. Similarly, the third rack plate 27 begins to descend, so that the second clamping ring 29 will contact the inner bottom wall of the belt positioning tube 15, thereby improving the gap between the internal structure of the connecting tube 16 and the inner wall of the positioning tube 15 The stable connectivity improves the clamping effect to a certain extent, and solves the problem of poor fastening of bolts used in the past. At the same time, when the blade body 17 needs to be rotated and ground, the oil cylinder 14 is moved downward. After rotating to the adjusted angle, the oil cylinder 14 is opened again to clamp the positioning cylinder 15 and the connecting cylinder 16. When the first rack plate 13 begins to rise, the second rack plate 21 begins to rise, and the third rack plate 27 begins to descend. As a result, the third rack plate 27 will drive the first connecting ring 30 and the first pull rope 31 to descend as a whole, and then the first pull rope 31 can be limited to a certain position by the limiting roller 32, so that the first pull rope 31 is stably pulled downward by the first connecting ring 30. After the first pull rope 31 is pulled, The fixing column 34 can be pulled to move leftward inside the slide groove, so that the slider 35 and the limiting frame 36 can be uniformly moved leftward, so that the second stretching 37 will also move leftward to a certain extent, and then the second stretching 37 is sleeved inside the sleeve 48 to limit the second stretching 37 to a certain extent, and then the second stretching 37 can pull the second connecting ring 45 and the connecting spring 44 to move leftward to a certain extent, so that the third connecting ring 46 will pull the second contact plate 47 to move leftward to a certain extent, and the two groups of piston cylinders 41 can provide a certain stability for the leftward movement of the second contact plate 47, and at the same time, the limiting plate 42 and the limiting ring 43 are used to prevent the connecting spring 44 from bending during the leftward movement, so that the second contact plate 47 will fit the cutting edge of the blade body 17,The first abutment plate 39 and the second abutment plate 47 are used to clamp the cutting edge of the blade body 17 to a certain extent, thereby further improving the clamping effect of the blade body 17. At the same time, the design of the first abutment plate 39 and the processing layer 40 can also scrape off the burrs on the cutting edge to a certain extent, thereby ensuring the processing effect of the blade body 17 during operation. The above is all the working principles of the present invention.
