Abstract

The utility model relates to a catapult device, which belongs to the field of toys. The central circle of a common catapult with a chord line is fixed in a circle ring at the front lower part of a front ejecting chute. The front ejecting chute is in a long columnar shape. An empty sliding chute with a semicircular or square tangent plane is formed parting the middle of a long columnar upper surface of the front ejecting groove, and two short vertical bending rotating shafts are arranged at both sides of the back part of the front ejecting chute respectively and are inserted into side holes at the front end of a back ejecting chute. The back ejecting chute has the same arrangement as the front ejecting chute as follows: an empty sliding chute communicated with the front ejecting chute is arranged on the back ejecting chute; a circular front handle is arranged at the front lower part of the back ejecting chute; the back end of the back ejecting chute is connected with a back handle having a square tangent plane and an arc upward-bending half back part; an elliptic vertical hole is formed on the back part of the back ejecting chute; an elliptic and columnar chord hanging column inserted in the vertical hole extends out of the back ejecting chute; two side vertical columns vertically extend from both sides of the lower end of the chord hanging column respectively; a spring sheet fixed under the back ejecting chute is positioned under the chord hanging column and is used for supporting the chord hanging column; the back end of the chord hanging column penetrates and is clamped in a chute hole at the middle part of the front part of an ejector in an arc sheet shape, and the middle part of the ejector is threaded on a steel wire fixed under the back handle. The catapult device can be accurately used for ejecting arrows, balls and ejection-type toy planes.

Description

Ejector

One, technical field

Ejector belongs to the toy field, relates to the ejector structure, particularly has the structure of the ejector of shell fragment bow and bowstring.

Two, background technology

Common archery tortuous bow and running fire arrow, both aiming function are all very poor.

Three, summary of the invention

The utility model is a kind of ejector that aims at better function of invention.

1, technical scheme

Ejector is that the tortuous bow middle part of the common tool string of a musical instrument is drawn a circle to approve in the circle ring of preceding emission groove front lower place; Before emission flute length column, upper central have a tangent plane to insert in the back emission front of the slot side opening for respectively having a weak point to hang down on semicircle or square empty chute, the both sides, rear portion to curve axle; Back emission groove is identical with preceding emission groove; Also there are empty chute, the front lower place of the preceding emission of connection groove to have round front hand grip, a rear end to connect back handle curved under the square latter half of arcuation of a undercut face above; There is the ellipse hole of hanging down at back emission groove rear portion; Hanging down is inserted with an oval column string hanging column in the hole and stretches out above the back emission groove, and two each the side drawdowns in string hanging column lower end go out two sides post that hangs down, and has below the string hanging column spring leaf that a slice is fixed in below the back emission groove that it is held; Wear in the slotted eye that is sandwiched in arc curved piece shape firing device front, center the string hanging column rear end, and the firing device middle part is through on the steel wire that is fixed under the back handle.

2, beneficial effect

Can accurately launch arrow, ball, ejection type toy airplane.
