[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Referring to Figures 1, 2, and 4, an embodiment of this utility model discloses an adjustable cutting length shredder, comprising: a shredder body 1; a fixing frame 2 fixedly connected to the outer surface of the shredder body 1; a motor 3 fixedly connected to the upper surface of the fixing frame 2; a bevel gear 4 fixedly connected to the output end of the motor 3; a bevel gear 5 meshing with the outer surface of the bevel gear 4; a connecting rod 6 fixedly connected to the outer surface of the bevel gear 5; a bulletproof frame 7 fixedly connected to one end of the connecting rod 6; and an identification box 14 fixedly connected to the outer surface of the shredder body 1. The inside of the label box 14 contains a label. The outer surface of the main body 1 of the shredder is fixedly connected to a protective cover 15. The positions of motor 3, bevel gear 4 and bevel gear 5 are located inside the protective cover 15. The outer surface of the protective cover 15 is provided with a heat dissipation vent, which is located opposite to the position of motor 3. The outer surface of the protective cover 15 is fixedly connected to a limit block 16. The outer surface of the limit block 16 is in contact with the upper surface of the bulletproof frame 7. The position of the bulletproof frame 7 is located outside the main body 1 of the shredder. The outer surface of the connecting rod 6 is rotatably connected to the fixed frame 2.

[0022] Specifically, the main body 1 of the wire cutter consists of a drive device, a conveying device, and a cutting device, etc., and is used to cut galvanized iron wire. When the cam of the cutting device rotates, its specific shape will cause the blade to contact the iron wire within a specific time, thereby achieving cutting. By changing the position of the cam and the blade with different shapes, different cutting length requirements can be met. The bulletproof frame 7 is outside the cutting device of the main body 1 of the wire cutter. The conveying device of the main body 1 of the wire cutter transports a portion of the galvanized iron wire into the bulletproof frame 7, and then the cutting device of the main body 1 of the wire cutter cuts it. After the galvanized iron wire is cut, it falls into the designated position through the inclined bulletproof frame 7. At the same time, the bulletproof frame 7 prevents the cut iron wire from splashing. This is the prior art. The motor 3 on the fixed frame 2 rotates the bevel gear 4, so that the bevel gear 5 meshing with the bevel gear 4 can rotate. The rotation of the bevel gear 5 causes the connecting rod 6 to rotate. The rotation of the connecting rod 6 allows the bulletproof frame 7 to adjust the angle.

[0023] Referring to Figures 2 and 3, a mounting bracket 8 is fixedly connected to the lower surface of the bulletproof frame 7, a motor 9 is fixedly connected to the outer surface of the mounting bracket 8, a lead screw 10 is fixedly connected to the output end of the motor 9, a movable frame 11 is threadedly connected to the outer surface of the lead screw 10, an extension tube 12 is fixedly connected to one end of the movable frame 11, the inner wall of the extension tube 12 is slidably connected to the bulletproof frame 7, a guide rod 13 is fixedly connected to the inner wall of the mounting bracket 8, the outer surface of the guide rod 13 is slidably connected to the movable frame 11, one end of the lead screw 10 is rotatably connected to the mounting bracket 8, and the outer surface of the movable frame 11 is slidably connected to the mounting bracket 8.

[0024] Specifically, the mounting bracket 8 is fixed below the bulletproof frame 7. The motor 9 on the outside of the mounting bracket 8 rotates the lead screw 10, which allows the movable bracket 11, which is threadedly connected to the lead screw 10, to move. The movement of the movable bracket 11 can move the extension tube 12. The length of the bulletproof frame 7 can be adjusted by extending and retracting the extension tube 12, and the position of the wire slippage can be changed as needed. A guide rod 13 is fixed on the inner side of the mounting bracket 8. The guide rod 13 provides guidance for the movement of the extension tube 12 and prevents the extension tube 12 from deviating during movement.

[0025] Working principle: After the galvanized iron wire is cut, it falls into a designated position through the inclined bulletproof frame 7. At the same time, the bulletproof frame 7 prevents the cut iron wire from flying. Then, the motor 3 on the fixed frame 2 rotates the bevel gear 4, which in turn rotates the bevel gear 5 that meshes with the bevel gear 4. The rotation of the bevel gear 5 causes the connecting rod 6 to rotate, and the rotation of the connecting rod 6 allows the bulletproof frame 7 to be adjusted in angle. The motor 9 on the outside of the mounting frame 8 rotates the lead screw 10, which causes the movable frame 11, which is threaded to the lead screw 10, to move. The movement of the movable frame 11 moves the extension tube 12. The length of the bulletproof frame 7 can be adjusted by extending and retracting the extension tube 12. A guide rod 13 is fixed on the inside of the mounting frame 8. The guide rod 13 provides guidance for the movement of the extension tube 12 and prevents the extension tube 12 from deviating during movement.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
