Abstract

The utility model discloses a portable cut-off knife, and belongs to the technical field of cutting tools. The portable cut-off knife solves the problems that an existing membrane sampling cut-off knife is complex in structure, large in size, inconvenient for maintenance of knife blades, and low in cutting off efficiency. The portable cut-off knife comprise a knife frame provided with an H-shaped cross section, the knife frame is composed of a top plate, base seats and a connecting plate used for connection of the top plate and the base seats, a sliding groove is formed in the connecting plate along the longitudinal direction, a slider is sleeved in the sliding groove, the two ends of the slider are respectively provided with a slider pin, the base seats arranged on the two sides of the connecting plate are respectively provided with a knife seat, the knife seats are fixedly installed on the slider pins, and knife blades and knife handles are fixedly installed on the knife seats. When used, the portable cut-off knife is placed on a sample membrane, the handles are pulled to enable the knife seats to parallelly move along the base seats, and the membrane is cut through the knife blades fixed on the knife seats. The portable cut-off knife is convenient to operate, simple in structure, and easy to carry, place and maintain. The knife blades are generally-used double-face blades, and time and cost are saved.

Description

Portable cut-off knife

Technical field

The utility model belongs to the crop tool technical field, particularly the cutter used of a kind of cutting plastic sheeting.

Background technology

Plastic sheeting is being carried out the test machines performance, during as tensile strength performance, elongation at break, elasticity modulus test, need to take a sample to film with cut-off knife, traditional Film sampling cut-off knife is cutting knife type or pulley type, its cutter frame structure is complicated, bulky, take up room large, use inconvenience, and blade is special-purpose cambered blade, in case blade passivation, its regrinding work is complicated, even undertaken by specialized factory, wastes time and energy; Perhaps carry out the replacing of whole cambered blade, but replacement cost is high, seriously dallies over one's work the time, impact is normally produced.

Summary of the invention

Existing Film sampling cutter structure is complicated, bulky in order to solve, the problem of blade inconvenient maintenance, and the utility model provides a kind of portable cut-off knife, and its technical scheme is as follows:

Portable cut-off knife, comprise that a cross section is I-shaped knife rest, knife rest is made of the connecting plate of top board, base and connection top board and base, be vertically arranged with chute on connecting plate, be set with slide block in chute, respectively there is a slide block pin at slide block two ends, respectively are provided with a tool rest on the base of connecting plate both sides, tool rest is fixedly mounted on slider pin and nails on, and is installed with blade and handle on tool rest.

As preferred version of the present utility model:

Stretch out outside tool rest the termination of described slide block pin, has thread segment on the termination of slide block pin, blade is arranged on one of them slider pin and nails on, hold(ing)-down clip is arranged on another slider pin and nails on, be positioned at blade and hold(ing)-down clip the outside slide block pin thread section on wing nut is installed, blade and hold(ing)-down clip are fastened on tool rest by wing nut.

During use, above-mentioned portable cut-off knife is positioned on the sampling film, base is smooth plate armature, be equivalent to guide rail, pull handle to make tool rest along the base parallel, sliding pin cuts film along the chute parallel by the blade that is fixed on tool rest, the width of knife rest is the width of the film that cuts out, thereby makes the dimensional accuracy of thin-film width obtain strict guarantee.The portable cut-off knife of the utility model is easy to operate, simple in structure, is easy to carry, places.Blade is universal double-edged razor blade, after using a period of time, occurs the burr flaw during for fear of film slitting, can quality is fully guaranteed by allowing blade replacement more, saves time and cost.

Fig. 2 is that A-A in Fig. 1 is to cutaway view.

The specific embodiment

Portable cut-off knife as depicted in figs. 1 and 2:

Comprise that a cross section is I-shaped knife rest 1, knife rest 1 is made of the connecting plate 3 of top board 2, base 4 and connection top board 2 and base 4, be vertically arranged with chute 5 on connecting plate 3, be set with slide block 6 in chute 5, respectively there is a slide block pin 7 at slide block 6 two ends, respectively be provided with a tool rest 8 on the base 4 of connecting plate 3 both sides, tool rest 8 is fixedly mounted on slide block pin 7, is installed with blade 9 and handle 12 on tool rest 8.

Stretch out outside tool rest 8 termination of described slide block pin 7, has thread segment on the termination of slide block pin 7, blade 9 is arranged on one of them slide block pin 7, hold(ing)-down clip 10 is arranged on another slide block pin 7, be positioned on slide block pin 7 thread segments in blade 9 and hold(ing)-down clip 10 outsides wing nut 11 is installed, blade 9 and hold(ing)-down clip 10 are fastened on tool rest 8 by wing nut 11.

During use, above-mentioned portable cut-off knife is positioned on the sampling film, base 4 is smooth plate armature, be equivalent to guide rail, pull handle 12 to make tool rest 8 along base 4 parallels, slide block 6 cuts film along chute 5 parallels by the blade 9 that is fixed on tool rest 8.
