Description

A kind of bag opener for plastic bags

Technical field

The cutter that the present invention relates to use in the daily life is specifically related to a kind of bag opener for plastic bags.

Background technology

People touch increasing plastics sacked goods in daily life, therefore, it is also more and more frequent to open plastic bag, in the prior art, generally be the sawtooth pattern mouth opening that utilizes above the plastic bag, be torn by hand plastic bag, and in the practical operation, it is that the sawtooth pattern mouth opening is malfunctioning that a lot of situations are also arranged, and is difficult to tear; Also there is plastic bag that mouth opening is not set, in this case, usually adopt scissors or knife to open plastic bag, but open plastic bag with scissors or knife, and it is dangerous, especially, when using scissors or knife, cause actual bodily harm easily for not agile the elderly of child, trick and the user that some are defective in body.

Summary of the invention

The objective of the invention is: a kind of bag opener for plastic bags safe in utilization is provided.

Technical scheme provided by the invention is as follows: a kind of bag opener for plastic bags, comprise a upper shell, have one on the sidewall of upper shell and advance sack, the end face of upper shell has a chute, the bottom surface of chute is provided with a slide rail, be equiped with a slide rest that can slidably reciprocate in the slide rail, slide rest is fixedly connected with a blade; Described upper shell under shed is fixedly connected with a lower cover, and the lower cover bottom surface has a reject chute, and the reject chute adjacency has a cutter groove, and described blade can slidably reciprocate in the cutter groove.

As being an improvement of the present invention, described blade end is provided with a leg-of-mutton twolip knife edge.

As a further improvement on the present invention, described slide rest is the intermediate plate that comprises two clamping blades, the intermediate plate bottom stretches out one and the slide block that cooperates of slide rail to the side, two intermediate plates stretch out chute, its top captive joint one sleeve, sleeve captive joint one push button, the push button lower surface is resisted against the end face of described chute.

As a further improvement on the present invention, described upper shell is a Long Circle housing, the bottom of upper shell end face has four connecting bores, and described lower cover protrudes upward four joint pins that cooperate with it, and upper shell and lower cover are connected by joint pin, connecting bore.

The present invention has the following advantages: blade is ensconced in the housing, has guaranteed that the user does not in use reach blade, and is safe in utilization; Blade has a cutter groove that cooperates with it, has guaranteed the validity of each action, and is easy-to-use.

The specific embodiment

Below in conjunction with accompanying drawing concrete embodiment is illustrated:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of bag opener for plastic bags, comprise a upper shell 1, have one on the sidewall of upper shell 1 and advance sack 12, the end face of upper shell 1 has an oblong chute 13, the bottom surface of chute 13 is provided with an oblong slide rail 14, be equiped with a slide rest that can slidably reciprocate 2 in the slide rail 14, described slide rest 2 comprises two posts, the intermediate plate 21 that borehole jack connects, two intermediate plates, 21 middle parts are provided with a knife holder slot 22, are provided with the registration mast 23 of two walls in the transverse slot in the knife holder slot 22, and registration mast 23 is connected with a blade 3, blade 3 and knife holder slot 22 cooperations are stretched out to intermediate plate 21 bottoms, and blade 3 ends are provided with a leg-of-mutton twolip knife edge 31; Described intermediate plate 21 bottoms to the side stretch out one and slide block 24, two intermediate plates 21 that cooperate of slide rail stretch out chute 13, its top captive joint one sleeve 25, sleeve 25 captive joints one push button 26, push button 26 lower surfaces are resisted against the end face of described chute 13;

Described upper shell 1 is a Long Circle housing, and the bottom of upper shell 1 end face has four connecting bores 15, and described lower cover 4 protrudes upward four joint pins 41, upper shell 1 and lower cover 4 being connected by joint pin, connecting bore that cooperates with it.Described lower cover 4 bottom surfaces have a reject chute 42, and reject chute 42 adjacencies have a cutter groove 43, and described blade 3 can slidably reciprocate in cutter groove 43.

During use, only need insert into sack 12 to a jiao of plastic bag, promote slide rest 2 then, make the knife edge 31 of blade 3 streak plastic bag to be cut, plastic bag be withdrawed from getting final product then, the plastic bag waste material of cutting will drop out from reject chute 42.

Above embodiment is explanation rather than restriction the present invention just, and upper shell 1 can be a Long Circle as described, also can be oblong, and is cylindrical; Described chute 13 can be a Long Circle, also can be oblong; Described upper shell 1 and lower cover 4 can be that joint pin, hole are connected, and also can be to glued joint or the like ..., of this sort conversion all falls within protection scope of the present invention.
