Referring to fig. 7 to 10, the basic structure and the using principle of the inverted safe hand shredder of the present embodiment are the same as those of embodiment 1, except that: in this embodiment, the necking section 2-1 is disposed at the middle position of the upper portion of the cup body 2, that is, the input port 2-2 is located at the center position of the cup body 2, in order to facilitate the arrangement of the positioning column 2-3, a positioning support 2-5 is disposed at the upper portion of the necking section 2-1, and the positioning column 2-3 is disposed at the center position of the cup body 2 by using the positioning support 2-5. The positioning support 2-5 preferably adopts an S-shaped beam which crosses the upper part of the necking section 2-1, and the positioning column 2-3 is arranged at the center of the positioning support 2-5 in a downward extending way. Of course, the neck section 2-1 can be slightly deviated from the center position to one side relative to the cup body 2, and the position of the positioning column 2-3 can be ensured to be matched with the upper part of the blade component 4 on the base 1 in an axial rotating and positioning way. Compared with embodiment 1, the inlet port 2-2 of the neck-down section 2-1 in this embodiment can be set larger, and the disadvantage is that the positioning bracket 2-5 needs to be set.

In another modification of this embodiment, the neck section 2-1 and the cup body 2 may have the same inner diameter, i.e., a vertically consistent straight cylindrical cup body structure is formed.

Above-mentioned embodiment 1 and embodiment 2's an inversion formula safety hand power shredder, through set up the shredder inversion, solved at one stroke that current hand power shredder exists eat material throw with pour the operation inconvenient, have potential safety hazard and shredder main part gripping reliability relatively poor two big technical problems, provide new design thinking for the safe nimble operation of hand power shredder, and the structural design of shredder is simple compact, and the outward appearance is novel, and the flexible operation is convenient. Referring to fig. 1 and 3, and fig. 7 and 9, when in use, the upper cover 5 is opened, and the garlic and other blocky food materials are added from the neck-reducing section 2-1 of the cup body 2 through the feeding port 2-2, and enter the bottom of the cup body 2 along the neck-reducing section 2-1, so that the food materials are not easy to overflow in the feeding process, and the hand-pulling shredder can be properly shaken in the feeding process; after the food materials are added, the upper cover 5 is covered, then the neck contracting section 2-1 is held by fingers of one hand, the main body part of the shredder is held by the thumb and the other four fingers, then the lower pull handles 3-1 are repeatedly pulled by the other hand, the blade assembly 4 in the cup body 2 is driven to rotate by the pull rope driving mechanism 3 to shred the food materials, the food materials at the bottom are turned up by the scraper 4-5 in the shredding process, the food materials are shredded more uniformly, and the shredding condition of the food materials can be observed through the transparent or semitransparent cup body 2; after the food materials are cut, the upper cover 5 is opened, the food materials are poured out from the feeding opening 2-2, in the process of pouring out the food materials, a plurality of lower handles 3-1 can be pulled, the food materials stuck at the bottom are scraped by the scraping plates 4-5, and the food materials are convenient to pour out. When cleaning, the upper cover 5 can be directly opened, and the input port 2-2 is flushed towards the water tap without contacting with a blade; or the cup body 2 can be detached from the base 1, the blade component 4 can be detached for thorough cleaning, and the cleaning and the drying can be carried out.

The utility model discloses an inversion type safe hand power shredder, it sets up to adopt the inversion structure with the shredder, utilizes the input mouth on the upper portion to add the edible material, directly pours out from the input mouth after the edible material is cut up, compares with current hand power shredder, and the operation is more nimble convenient, and edible material is added and is also more accurate stable with pouring out, is difficult to spill, and the whole operation process all need not to contact the blade, operates safelyr; and, through inverting the setting with the shredder, utilize the necking down section on cup upper portion as the portion of gripping of shredder, the necking down section part that the cup just can be held to finger tiger's mouth compares with current hand power shredder, and the shredder gripping is more reliable, is difficult for the slippage, has further improved the reliability and the security of operation.
