Mousetrap
Technical field
The present invention relates to a kind of daily necessities, relate in particular to a kind of mousetrap.
Background technology
Mouse serve as a soldier steathily food, spread disease, its fertility is extremely strong, and is very harmful to the mankind, therefore killing mouse is the long-range mission of face of mankind.The mousetrap of people's use now comprises the casing to open front, and the upper surface of the front portion of casing has puts the doorway, puts and is placed with the Qianmen in the doorway; There is stay cord in the upper surface system at Qianmen, during use, needs earlier the Qianmen to be taken away; In casing, place food, mouse will creep in the casing and eat food, and at this moment the Qianmen is put down; Mouse has just been caught, this mousetrap waste of manpower, and result of use is poor.
Summary of the invention
The purpose of this invention is to provide a kind ofly can kill rats automatically, mousetrap that result of use is good.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of mousetrap comprises the mousetrap casing; It is characterized in that: the both sides of the front portion of mousetrap casing are fixedly connected with long " U " shape frame, and the both sides at the rear portion of mousetrap casing are fixedly connected with short " U " shape frame, are connected with long stent connecting rod and short rack rod on long " U " shape frame and weak point " U " the shape frame respectively; Be connected with lever on the long stent connecting rod, be connected with the snap close piece on the short rack rod, the front end of lever is connected with the Qianmen through stay cord; The front portion of mousetrap casing has the hole; The Qianmen is positioned at the hole, the rear portion grafting push rod of mousetrap casing, and the lower end of push rod passes the lower surface of mousetrap casing; The rear end of lever is corresponding with the groove of snap close piece; The front end of snap close piece is corresponding with push rod, and the middle part of mousetrap casing lower surface is fixed with the Connection Block of inverted triangle, is connected with the base of equilateral triangle on the Connection Block.
In this structure, the upper surface of mousetrap casing has air-vent.
Advantageous effect of the present invention is: because the both sides of the front portion of mousetrap casing are fixedly connected with long " U " shape frame among the present invention, the both sides at the rear portion of mousetrap casing are fixedly connected with short " U " shape frame, are connected with long stent connecting rod and short rack rod on long " U " shape frame and weak point " U " the shape frame respectively; Be connected with lever on the long stent connecting rod, be connected with the snap close piece on the short rack rod, the front end of lever is connected with the Qianmen through stay cord; The front portion of mousetrap casing has the hole, and the Qianmen is positioned at the hole, the rear portion grafting push rod of mousetrap casing; The lower end of push rod passes the lower surface of mousetrap casing, and the rear end of lever is corresponding with the groove of snap close piece, and the front end of snap close piece is corresponding with push rod; The middle part of mousetrap casing lower surface is fixed with the Connection Block of inverted triangle; Be connected with the base of equilateral triangle on the Connection Block,, can avoid artificial guard so use when of the present invention; Directly can capture mouse automatically, result of use is good.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
A kind of mousetrap, the present invention is as shown in Figure 1, a kind of mousetrap; Comprise mousetrap casing 10, it is characterized in that: the both sides of the front portion of mousetrap casing 10 are fixedly connected with long " U " shape frame 3, and the both sides at the rear portion of mousetrap casing 10 are fixedly connected with short " U " shape frame 5; Be connected with long stent connecting rod 2 and short rack rod 7 on long " U " shape frame 3 and short " U " shape frame 5 respectively, be connected with lever 4 on the long stent connecting rod 2, be connected with snap close piece 8 on the short rack rod 7; The front end of lever 4 is connected with Qianmen 13 through stay cord 1, and the front portion of mousetrap casing 10 has the hole, and Qianmen 13 is positioned at the hole; The rear portion grafting push rod 9 of mousetrap casing 10; The lower end of push rod 9 passes the lower surface of mousetrap casing 10, and the rear end of lever 4 is corresponding with the groove of snap close piece 8, and the front end of snap close piece 8 is corresponding with push rod 9; The middle part of mousetrap casing 10 lower surfaces is fixed with the Connection Block 12 of inverted triangle, is connected with the base 11 of equilateral triangle on the Connection Block 12.In the present embodiment, the upper surface of mousetrap casing 10 has air-vent 6.
Use when of the present invention, earlier the present invention is turned forward, put some foods at the rear portion of mousetrap casing, mouse will get in the mousetrap casing in order to eat food like this; After mouse gets into the mousetrap casing, because the weight of mouse causes the hypsokinesis of mousetrap casing; At this moment push rod moves upward, and the front end of jack-up snap close piece is because the snap close piece flexibly connects with short rack rod; So the rear portion of snap close piece moves downward, thereby break away from lever, at this moment the front end of lever moves downward; The Qianmen is put down, and promptly the Qianmen of mousetrap casing is closed, and mouse just has been closed in the mousetrap casing.
