Abstract
The utility model discloses a collapsible type paper cutter, which comprises a blade, a tool rest and a handle, wherein the blade is disposed in the tool rest, the root of the tool rest is movably hinged with the front of the handle, the outer shape of the root of the tool rest is in a gear shape, the tooth valley is in a recessed semi-circular arc, a H-shaped column is movably mounted at the part of the back of the handle corresponding to the root of the tool rest, a compressed spring is arranged between one end of the H-shaped column and the inner side of the handle, the other end of the H-shaped column extends out of the handle and a column shoulder is arranged at the inner side of the end, the semidiameter of two ends of the H-shaped column is bigger than the semidiameter of the tooth valley and the semidiameter of the mid portion is smaller than the semidiameter of the tooth valley. The utility model has the advantages that by using the gear structure, the tool rest, in the folding position or in the fully unfolding position, can be locked by the H-shaped column without the rotation, and the collapsible type paper cutter can operated simply and can be safe and practical.
Description
Technical field
The utility model relates to a kind of collapsible paper knife.
Background technology
At present, increasing collapsible paper knife appears on the market, for prevent tool rest in use accident amount to, this class paper knife often needs to be provided with the back of the body spring or locking plate tool rest is locked, but these lock mechanism operative are got up very inconvenient, and generally needing both hands to cooperate could open.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of above-mentioned existence, to provide a kind of simple in structure, safe and practical, collapsible paper knife simple to operate.
The utility model is achieved through the following technical solutions.
The utility model is a kind of collapsible paper knife, it includes blade, tool rest and handle body, blade is positioned in the tool rest, tool rest root and handle body front end are movably hinged, described tool rest root outline is gear shape, tooth paddy is the semicircular arc of depression, handle body back is movably installed with a H-column body at the position corresponding with the tool rest root, be provided with the compression spring between one end of this H-column body and the handle body inboard, the other end of this H-column body extends external this end inboard simultaneously of handle and is provided with post shoulder, and the two ends radius of this H-column body greater than the radius of tooth paddy simultaneously the radius of intermediate portion less than the radius of tooth paddy.
Above-mentioned handle body back is provided with a jacking block near the position of tool rest root, and this jacking block withstands the tool rest root when tool rest is opened to horizontal level.
Advantage of the present utility model is, utilizes gear structure, and no matter tool rest is in when to amount to the position still be the fully open position, and the H-column body can be locked and make it and can not rotate, and this structure operation is simple, and is safe and practical.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model H-column body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, shown in Figure 2, the utility model is a kind of collapsible paper knife, it includes blade, tool rest and handle body, blade is positioned in the tool rest, tool rest root 1 is movably hinged with handle body front end, described tool rest root 1 outline is gear shape, tooth paddy 2 is the semicircular arc of depression, handle body back is movably installed with a H-column body 3 at the position corresponding with tool rest root 1, be provided with the compression spring between one end of this H-column body 3 and the handle body inboard, the other end of this H-column body 3 extends external this end inboard simultaneously of handle and is provided with post shoulder 4, and the two ends radius of this H-column body 3 greater than the radius of tooth paddy 2 simultaneously the radius of intermediate portion less than the radius of tooth paddy 2.When wanting the release tool rest, only need press H-column body 3, utilize the little design of radius ratio tooth paddy 2 radiuses of H-column body 3 mid portions, tool rest is promptly rotatable; When decontroling H-column body 3, the end of H-column body 3 snaps in and can prevent in the tooth paddy 2 that tool rest from rotating.
The back of above-mentioned handle body is provided with a jacking block 5 near the position of tool rest root 1, and this jacking block 5 withstands tool rest root 1 when tool rest is opened to horizontal level.Like this, just can prevent that tool rest is to handle body back ovdersteering.
