Abstract
The utility model relates to the field of agricultural supplies, and particularly relates to a cutter adjustable in length. The cutter adjustable in length comprises a slide bar which is made of plastics, wherein scales are formed in the slide bar, cutter holders are symmetrically arranged on the slide bar, are connected with the slide bar through circular holes and are made of titanium alloy, grooves are formed in the middle parts of the cutter holders, the cutter holders are connected with blades through rotating shaft, the width of each blade is less than that of each groove, each blade is made of steel, the cutting edge is formed in the lower end of each blade, a handle is arranged on the back end of each blade, and a rubber anti-skid mat is arranged at the bottom of each cutter holder. The cutter adjustable in length has the beneficial effects that the structural design is reasonable and practical, the conception is ingenious and novel, the cutter is simple and convenient to use, and the purpose that the length of standard samples is consistent in sampling process of standard samples is achieved.
Description
Technical field
The utility model relates to agriculture articles for use fields, relates in particular to a kind of cutting knife of length adjustment.
Background technology
Paddy rice originates in Tropical Asian, after China widely plants, propagates into all over the world gradually.Paddy rice is the annual gramineae plant, and paddy rice institute knot is paddy in fact, and rear title rice or rice shell.Nearly half population in the world comprises the almost population in whole East Asia and Southeast Asia, all take rice as food.The existing material of depending on for existence to become the mankind of paddy rice.In the plantation growth course of paddy rice, paddy rice may be by courses of infection, to form the infected area after infecting on paddy rice, for kind and the source of infection of searching germ, often the infected area of paddy rice need to be cut down test, during existing indoor paddy rice germ standard specimen sampling, all with cutter, it to be blocked, but in the situation that require obtained standard specimen length consistent, manually can't accurately complete, this will affect the experimental comparison effect.
The utility model content
The utility model is for the prior art above shortcomings, the cutting knife of novel a kind of length adjustment is provided, two tool rest positions on slide bar are adjustable, can regulate two distances between tool rest according to the scale on slide bar, and standard specimen length is consistent purpose in the sampling standard specimen to reach.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of cutting knife of length adjustment comprises slide bar, and described slide bar is made of plastics, described slide bar is provided with scale, is arranged with tool rest on described slide bar, and described tool rest is connected with slide bar by circular hole, described tool rest is made by titanium alloy, described tool rest middle part is provided with groove, and described tool rest is connected with blade by rotating shaft, and described blade width is less than recess width, described blade is formed from steel, described blade lower end is provided with blade, and described blade rear end is provided with handle, and described tool rest bottom is provided with the rubber antiskid pad.
The described handle outside is provided with anti-skidding projection.
The utility model beneficial effect: reasonable in design is practical, and the novelty that is skillfully constructed is easy to use, can reach the more consistent purpose of standard specimen length in the sampling standard specimen.
Description of drawings
Fig. 1 is the cutter structure schematic diagram of length adjustment described in the utility model.
In figure:
The 1-slide bar; The 2-scale; The 3-tool rest; The 4-circular hole; The 5-groove; The 6-blade; The 7-blade; The 8-handle.
The specific embodiment
The below is described in further detail the utility model according to drawings and embodiments:
as shown in Figure 1, the cutting knife of a kind of length adjustment of the present utility model, comprise slide bar 1, described slide bar 1 is made of plastics, plastics have certain frictional force, tool rest 3 after can guaranteeing to move can not move phenomenon by occurrence positions in use, described slide bar 1 is provided with scale 2, scale 2 is used for weighing the distance between two tool rests 3, be arranged with tool rest 3 on described slide bar 1, described tool rest 3 is connected with slide bar 1 by circular hole 4, can slide on slide bar 1 by circular hole 4 tool rests 3 on tool rest 3, described tool rest 3 is made by titanium alloy, the titanium alloy quality is light, compressive resistance is strong, be difficult for being damaged and being corroded, described tool rest 3 middle parts are provided with groove 5, can place blade 6 in groove 5, described tool rest 3 is connected with blade 6 by rotating shaft, can rotate along tool rest 3 by rotating shaft blade 6, described blade 6 width are less than groove 5 width, guarantee that blade 6 can all be placed in the groove 5 of tool rest 3, described blade 6 is formed from steel, steel is comparatively solid, can increase service time, described blade 6 lower ends are provided with blade 7, blade 7 is used for cutting plants, described blade 6 rear ends are provided with handle 8, handle 8 is the hand griping position of moving blade 6, described handle 8 outsides are provided with anti-skidding projection, anti-skidding projection plays certain skidproof effect.Described tool rest bottom is provided with the rubber antiskid pad, prevents the tool rest sidesway.
During use, length according to indoor paddy rice germ standard specimen sampling, move the position of tool rest 3 on slide bar 1 by circular hole 4, scale 2 on observation slide bar 1 moves to suitable stopping with two tool rests 3 and moves behind the position, because slide bar 1 is made of plastics, plastics have certain frictional force, can guarantee two tool rest 3 positions after mobile phenomenon that can at will not be shifted in use.Hold handle 8 two blades 6 are produced in the groove 5 of tool rest 3, the cut position of cutting that two tool rests 3 is placed on paddy rice is set up, rotating blade 6 simultaneously again, and the blade 7 on blade 6 will intercept the sampling standard specimen of paddy rice get off, to test.Do not become because the position of two tool rests 3 on slide bar 1 is fixing, the length of the sample that can guarantee when again intercept with it to take a sample is consistent, the reliability of increase experimental result.
Claims (2)
