Abstract

The utility model discloses a folding paper cutter. The folding paper cutter consists of a blade, a tool apron and a handle body; the back of the handle body is provided with a locking device for locking the tool apron; the locking device comprises a guide rail groove, a push block and a compression spring; the push block consists of a locking rod and a push rod; the guide rail groove is formed in a back rod on the back of the handle body; one end of the guide rail groove is opened, while the other end is closed; the locking rod and the compression spring are connected together and placed in the guide rail groove; the push rod extends out of the back rod from a through hole communicated with the guide rail groove; and the end part where the tool apron and the handle body are connected is provided with a blind hole for inserting the locking rod. The folding paper cutter has the advantages that: a locking switch is positioned at the front end of the handle body, one hand can hold the handle body and the thumb of the hand can push the push block to finish the unlocking process of the tool apron, meanwhile, the structure has small volume, the elastic potential energy of the compression spring is lower, and the operation is labor-saving.

Description

A kind of collapsible paper knife

Technical field

The utility model relates to a kind of instrument of cutting a sheet of paper, and more particularly, relates in particular to a kind of collapsible paper knife.

Background technology

Present collapsible paper knife, the locking device of its locking tool rest generally is the back of the body spring that is positioned at handle body back, break away from tool rest bayonet socket realization release by impel its front end to lift by lower back spring rear end, the active force that this structure need put on back of the body spring rear end is bigger, and the rear end of back of the body spring is positioned at the tail end of handle body, hand operated is got up also inconvenient, needs the another hand to catch the operation easily of holding steadily just of the front end of handle body.

The utility model content

The purpose of this utility model is in order to solve the problem of above-mentioned existence, and a kind of rapid operation, collapsible paper knife easily are provided.

The utility model is a kind of collapsible paper knife, it is made up of blade, tool rest, handle body, handle body back is provided with the locking device of locking tool rest, described locking device comprises guide-track groove, pushing block and compression spring, pushing block is made up of securing rod and catch bar, guide-track groove is arranged in the back of the body bar at handle body back, this guide-track groove one end opening one end sealing, securing rod connects with the compression spring and places guide-track groove, catch bar is outside the port that is communicated with guide-track groove extends to back of the body bar, and the end that tool rest and handle body join is provided with and holds the blind hole that securing rod inserts.

Above-mentioned securing rod and catch bar are formed as one, and both are vertical mutually.

The width of above-mentioned port is greater than the width of catch bar through the port position.

Advantage of the present utility model is, locking switch is positioned at the front end of handle body, and the thumb that hand promptly can be held handle body and this hand can promote the releasing process that pushing block is finished tool rest, and this structural volume is little simultaneously, the elastic potential energy of compression spring is smaller, and it is more laborsaving to operate.

Description of drawings

Fig. 1 is this practical overall structure schematic diagram;

Fig. 2 is the structural representation of the utility model locking device.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1, the utility model is a kind of collapsible paper knife, it is by blade, tool rest, the handle body is formed, handle body back is provided with the locking device of locking tool rest, described locking device comprises guide-track groove 2, pushing block 3 and compression spring 4, pushing block 3 is integrally formed by orthogonal securing rod 31 and catch bar 32, guide-track groove 2 is arranged in the back of the body bar 1 at handle body back, this guide-track groove 2 one end openings one end sealing, securing rod 31 connects with compression spring 4 and places guide-track groove 2, catch bar 32 is outside the port 5 that is communicated with guide-track groove 2 extends to back of the body bar 1, and the end that tool rest and handle body join is provided with and holds the blind hole 6 that securing rod 31 inserts.

As shown in Figure 2, can move forward and backward in order to guarantee pushing block 3, the width of port 5 is greater than catch bar 32 width through ports 5 positions, and this width should take in guide-track groove 2 for well fully can make securing rod 31 be positioned at back of the body bar 1 outer part.
