Abstract

The utility model relates to a blade bending device which comprises an upper pressing block and a lower pressing block. The lower end face of the upper pressing block is provided with a protruding blade bending pressing block, and the bottom end of the blade bending pressing block is higher than a blade. The upper end face of the lower pressing block is provided with a cylinder, and the blade bending pressing block is located in front of the cylinder. A hole is formed in the end face of the cylinder downwards, and the hole is internally provided with a spring. The top end of the spring is in fixed contact with the upper pressing block in an abutted mode, and the position, relatively located on the rear side of the blade bending pressing block, of the lower pressing block is provided with a blade limiting block. When the blade is bent, the bent waste blade can fall off from a specific place and cannot fly randomly, and therefore the human safety of a consumer is protected. In addition, the blade bending device is simple in structure, low in cost and convenient to use.

Description

A kind of blade tabs device

Technical field

The utility model relates to a kind of blade tabs device.

Background technology

On market, the tabs device of more common cutter self band is the clasp of opening this blade on afterbody plastic parts or metalwork, because tabs mouth and blade have very large gap, in the time of tabs, the inertia force of blade breakages moment can make the uncontrolled unrest of blade being folded down fly, and easily causes unnecessary injury to consumer.

Utility model content

Technical problem to be solved in the utility model is: the blade tabs device that when a kind of jack knife sheet is provided, blade can disorderly not fly.

For addressing the above problem, the technical solution adopted in the utility model is: a kind of blade tabs device, comprise upper holder block and lower lock block, on the lower surface of described upper holder block, be provided with the tabs briquetting of a protrusion, the bottom of described tabs briquetting is higher than blade position, on the upper surface of described lower lock block, be provided with a cylinder, described tabs briquetting is positioned at cylindrical front, described cylinder end face is offered porose downwards, in described hole, be provided with a spring, top and the upper holder block of described spring fix conflict, the rear side that is relatively positioned at tabs briquetting on described lower lock block is provided with a blade limited block.

Preferably, described cylindrical height is a little more than blade position.

Preferably, described tabs briquetting is positioned at the front side 3-5mm of blade limited block.

Preferably, described cylinder is positioned at the rear side 3-5mm of tabs briquetting.

Preferably, described lower lock block interior shape matches with razor blade for carving tool frame profile.

The beneficial effects of the utility model are: the utility model is in the time of jack knife sheet, and being folded down the discarded blade coming can drop out from specific place, can disorderly not fly; thereby protect consumer's personal safety; and the utility model is simple in structure, cost is lower, easy to use.

Detailed description of the invention

The utility model is further described by specific embodiment below in conjunction with accompanying drawing.

As shown in Figure 1, described a kind of blade tabs device, comprise upper holder block 1 and lower lock block 2, on the lower surface of described upper holder block 1, be provided with the tabs briquetting 3 of a protrusion, the bottom of described tabs briquetting 3 is higher than the position of blade 8, on the upper surface of described lower lock block 2, be provided with a cylinder 4, described tabs briquetting 3 is positioned at the front of cylinder 4, the end face of described cylinder 4 offers porose 41 downwards, in described hole 41, be provided with a spring 5, the top of described spring 5 and upper holder block 1 fix conflict, as shown in Figure 2, the rear side that is relatively positioned at tabs briquetting 3 on described lower lock block 2 is provided with a blade limited block 6, the height of described cylinder 4 is a little more than the position of blade 8, the spring 5 that makes to be arranged in hole 41 is fixed more firm, described tabs briquetting 3 is positioned at the front side 3-5mm of blade limited block 6, due to lever principle, can be very light when now the blade 8 of required tabs in tabs device being fractureed, described cylinder 4 is positioned at the rear side 3-5mm of tabs briquetting 3, cylinder 4 now has also played the auxiliary spacing effect of a blade 8, described lower lock block 2 interior shapes match with razor blade for carving tool frame 7 profiles, therefore, in the time that the front end of cutter inserts in tabs device, play the good positioning action of a tool setting horse 7.

When use, cutter front end inserts in tabs device, because lower lock block 2 interior shapes and razor blade for carving tool frame 7 profiles match, therefore, in the time that the front end of cutter inserts in tabs device, play the good positioning action of a tool setting horse 7, in the time that blade 8 pushes up the blade limited block 6 on lower lock block 2, finger presses upper holder block 1 starts tabs with lower lock block 2, be positioned at again the front side 3-5mm of blade limited block 6 because of tabs briquetting 3, in required tabs blade 8 foremost, due to lever principle, can be very light when now blade 8 fractures, the discarded blade fractureing is due to restricted in tabs device, can disorderly not fly, so can only drop out from a specific side, thereby Protection of consumer personal safety.
