DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a universal mechanical rotating tool holder with a protective function, comprising a tool holder 1 and a protective box 5, blades 2 are fixedly installed on the four sides of the tool holder 1, the upper half of the tool holder 1 is penetrated by a limiting bolt 3, and the penetration is threaded, a steering handle 4 is rotatably installed on the upper surface of the tool holder 1, the tool holder 1 penetrates the protective box 5, and the penetration is fitted, a limiting mechanism 6 is fixedly installed on the upper surface of the protective box 5, and a cleaning mechanism 7 is fixedly installed on the side of the tool holder 1.

[0021] Specifically, the cleaning mechanism 7 includes a metal block 71, the metal block 71 is fixed to the side of the tool holder 1, a spring 72 is fixed to the bottom of the metal block 71, a cleaning block 73 is fixed to the end of the spring 72 away from the metal block 71, the metal block 71, the spring 72 and the cleaning block 73 each have four groups, which are fixed to the four sides of the tool holder 1, and the inner wall of the protective box 5 is fixed with a metal column 74. Four groups of metal columns 74 are fixed on the inner wall of the protective box 5, and the metal columns 74 can contact the cleaning blocks 73 when moving up and down.

[0022] Specifically, the limiting mechanism 6 includes a fixed block 61, a fixed block 61 is fixed on the upper surface of the protection box 5, a limiting spring 62 is fixed on the inner side of the fixed block 61, a slider 63 is fixed on the end of the limiting spring 62 away from the fixed block 61, the slider 63 passes through the positioning block 64, and is slidably connected with the positioning block 64 at the penetration point, a limiting block 65 is fixed on the upper surface of the tool holder 1, when the protection box 5 is raised, the slider 63 passes through the limiting block 65, and is slidably connected at the penetration point, a limiting hole 66 is provided on the front side of the tool holder 1, and a rotating shaft 66 is provided on the front side of the tool holder 1 for rotation 7. The rotating shaft 67 passes through the gear 68, and the outer wall of the rotating shaft 67 and the inner wall of the gear 68 are fixedly connected. When the rotating shaft 67 rotates, the gear 68 can be driven to rotate together. A handle 69 is fixed to the end of the rotating shaft 67 away from the tool holder 1. When the handle 69 rotates, the rotating shaft 67 can be driven to rotate together. A movable hole 611 is opened on the front side of the protection box 5. A rack 610 is fixedly installed on the inner wall on the same side of the movable hole 611, and the tooth surface of the rack 610 is meshed with the gear 68. When the gear 68 rotates, the rack 610 can be driven to move up and down.

[0023] Working principle: when the protective box 5 needs to be lowered, first slide the slider 63 toward the fixed block 61 so that the slider 63 no longer contacts the limit block 65, and then turn the handle 69 counterclockwise. The handle 69 drives the rotating shaft 67 fixed to it to start rotating, and the rotation of the rotating shaft 67 drives the gear 68 to rotate. When the gear 68 starts to rotate counterclockwise, the rack 610 meshing with it moves downward. During the downward movement of the protective box 5, the slider 63 is fitted with the tool holder 1 by the thrust of the limiting spring 62. When the slider 63 moving with the protective box 5 reaches the position of the limiting hole 66, the slider 63 passes through the limiting hole 66 by the thrust of the limiting spring 62, thereby completing the limiting of the protective box 5.

[0024] When the protection box 5 moves downward, the metal column 74 fixed on the inner wall of the protection box 5 also moves together. During the downward movement of the metal column 74, the metal column 74 fits the cleaning block 73 and pushes the cleaning block 73 to move downward together. The left side wall of the cleaning block 73 fits the blade 2 and brings down the debris remaining on the blade 2. When the protection box 5 is raised, the cleaning block 73 moves upward under the pulling force of the spring 72.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
