[0032] like Figures 1 to 6The knife lock structure for a knife storage magazine shown in the figure comprises: a knife row body 1, with a plurality of knife lock openings 11 provided on opposite sides thereof, an annular protrusion 111 provided within the knife lock opening 11 for positioning the knife handle, and a positioning key 2 provided in the middle of the edge of the knife lock opening 11, and the positioning key 2 is embedded in the positioning groove of the knife handle to prevent the knife from rotating; a knife lock assembly is provided at the opening of the knife lock opening 11, and comprises a spring plate 3 located at the upper end of the opening and a pressing plate 4 located at the lower end of the opening;

[0033] Among them, the spring sheet 3 includes a fixed part 31, and an elastic paddle 32 formed by bending and extending along the lower edge of the fixed part 31. The elastic paddle 32 is arranged corresponding to the annular protrusion 111 and is used to clamp the embedded tool. The pressing sheet 4 is arranged on a side of the knife handle of the knife row body 1 and is used to press the bottom of the end face of the knife handle.

[0034] In the present invention, the plurality of locking blades 11 on both sides of the knife row body 1 are symmetrically arranged, or the plurality of locking blades 11 on both sides of the knife row body 1 are staggered. When the tool has not entered the locking blade 11, the spring paddle is in a free state. When the tool handle fully enters the locking blade 11, the tool handle is subjected to the dual positioning action of the annular protrusion 111 and the positioning key 2, so that the tool is fixed in the locking blade 11. At this time, the elastic paddle 32 of the spring plate 3 is squeezed, and its reaction force applies a thrust toward the inside of the locking blade 11 on the outer cylindrical surface of the tool handle to lock the tool handle in the locking blade 11. At the same time, the pressing plate 4 acts on the end face of the tool handle away from the tool, pressing the bottom of the end face of the tool handle to ensure the horizontality of the tool axis. In the present invention, the number of tools is increased by the arrangement of the knife row body 1, thereby meeting the processing and use requirements of multiple tools. The arrangement of the spring plate 3 and the pressing plate 4 ensures the stability of the tool in the locking blade 11, thereby improving the reliability of the tool fixation.

[0035] The locking blade 11 of the present invention includes a semicircular positioning groove 112, and an upper sliding section 113 and a lower sliding section 114 located at the open end of the semicircular positioning groove 112 and arranged parallel to each other; the spring leaf 3 is located in the upper sliding section 113, and the pressing piece 4 is located in the lower sliding section 114, and provides a pressing force in the axial direction to the end face of the handle at the connection position with the semicircular positioning groove 112.

[0036] Specifically, the spring pick is in a free state, and its end protrudes from the inner side surface of the upper sliding section 113. When the tool slides in between the upper sliding section 113 and the lower sliding section 114, the elastic pick 32 will be gradually squeezed by the outer cylindrical surface of the tool handle until the elastic pick 32 originally protruding from the upper sliding section 113 remains flush with the inner side surface of the upper sliding section 113; when the tool handle completely enters the semicircular positioning groove 112, the tool handle is subjected to the dual positioning action of the annular protrusion 111 and the positioning key 2, so that the tool is fixed in the locking blade 11. At this time, the outer cylindrical surface of the tool handle is not in contact with the inner side surfaces of the upper sliding section 113 and the lower sliding section 114, and the elastic pick 32 located in the upper sliding section 113 acts on the tool handle to lock the tool handle in the locking blade 11. At the same time, the pressing piece 4 acts on the end face of the tool handle away from the tool to press the bottom of the end face of the tool handle.

[0037] In the present invention, a notch 11a is provided on the inner side of the locking blade 11 corresponding to the mounting position of the elastic paddle 32. When the tool enters the locking blade 11, the notch 11a provides space for the elastic paddle 32 to move, facilitating smooth entry of the tool while ensuring sufficient clamping force on the tool and improving the positioning stability of the tool.

[0038] As the tool enters, the elastic pick 32 is squeezed upward to reduce its inclination angle. When the tool is fully inserted, the elastic pick 32 will abut against the outer cylindrical surface of the handle. At this time, the abutment point is lower than the highest point of the handle. Therefore, in order to enable the tool to be smoothly removed from the locking blade 11, the end of the elastic pick 32 extends upward to form an arc-shaped surface 321 for abutting against the handle.

[0039] When the tool enters the locking edge 11 from the side, in order to ensure smooth entry of the tool and reliability of the clamping force, the pressing piece 4 is bent at both ends along the opening direction of the locking edge 11 away from the tool row body 1 to form a guide arc edge 41.

[0040] In the preferred embodiment, a gasket 5 is provided between the pressing piece 4 and the blade row body 1. By replacing different types of gaskets 5, the distance between the clamping surfaces can be adjusted to ensure the reliability of the clamping force.

[0041] In a preferred embodiment of the present invention, the fixing portion 31 comprises a middle plate 311 and two locking plates 312 disposed perpendicularly to the middle plate 311 at either end. The two locking plates 312 are fixed to opposite sides of the blade assembly body 1, and the lower edge of the middle plate 311 extends downward and bends toward the interior of the locking edge 11 to form the elastic paddle 32. The two locking plates 312 secure the spring piece 3 on both sides, improving the reliability of the spring piece 3's positioning within the blade assembly body 1.

[0042] In order to prevent the spring sheet 3 from rotating when the tool enters the cutting edge, thereby affecting the clamping force of the tool, fixing holes 312a are provided at the ends of the two locking plates 312 away from the middle plate 311, and the lengths of the two locking plates 312 are not equal.

[0043] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
