Abstract

A cat eye type catapult belongs to the field of shoot-off tools and solves the problems in the prior catapult with a fixing ring that rubber bands have much possibility to slide off in the process of shooting and to wind after shooting. The cat eye type catapult comprises a handle (1) and arc forks (2), is characterized in that a spacer (3) is longitudinally fixed in a fixing ring (4) at the upper end of each arc fork (2), and has the advantages that the rubber bands can not slide off in the process of shooting and can not wind after shooting, thereby increasing the precision and frequency of shooting.

Description

A kind of cat-eye type catapult

Technical field

The utility model belongs to and launches field of tool, is specifically related to a kind of catapult.

Background technology

Catapult is as a kind of ancient instrument that launches, and is just on the books as far back as The Spring and Autumn Period China's history records.Since catapult launch power than other launch instrument a little less than, therefore, all be used for being used as converter tools usually by people though in military combat, appeared the brilliance.Along with improving constantly of people's living standard and greatly enriching of recreation, catapult has been subjected to liking of people again, and catapult heat is also heating up gradually.The catapult fans often organize some catapult matches, and catapult also becomes a kind of sports instrument in as converter tools.

At present, modal catapult is stuck the catapult that has retainer ring for bow on the market, rubber band is enclosed within to link to each other with the skin pocket on the retainer ring again get final product.The retainer ring of this catapult is circle and smooth surface, and when the tension rubber band, because the instability of direction of pull, rubber band can be sliding to two lateral deviations along retainer ring, its position instability, thereby the precision that influence is launched.After launching out pellet shot from a slingshot, rubber band usually can be twisted strength and is intertwined, and at this moment just need rubber band be untied with hand, and this has just wasted the regular hour, has reduced and has launched frequency.

The utility model content

The purpose of this utility model is that rubber band is easy when launching slides, launches the problem that the back rubber band easily twines partially for the catapult that solves existing band retainer ring exists, and a kind of cat-eye type catapult is provided.This cat-eye type catapult have rubber band when launching sliding partially, launch the advantage that the back rubber band does not twine, launch precision and frequency thereby improved.

The technical solution of the utility model is:

This cat-eye type catapult comprises handle and bow fork, it is characterized in that the inside of sticking the retainer ring of end at bow vertically is fixed with partition;

Described partition has certain angle α, 45 °≤α＜90 ° to the inboard inclination of bow fork and with level;

One end relative position place of described retainer ring and partition has opening.

The utlity model has following beneficial effect:

The inside that the bow of this cat-eye type catapult is stuck the retainer ring of end vertically is fixed with partition, owing to adopt this structure, partition can be separated two rubber bands, thereby the situation that the stubborn strength of rubber band generation is twined after preventing to launch takes place; When finishing when launching, only need rubber band retracted next time and launch, wrapping phenomena can not take place in rubber band, launches frequency thereby effectively improved; Simultaneously, partition can play the effect of fixed position to rubber band, thus when preventing that rubber band is tightened up because the instability of direction of pull and precision is launched in, influence sliding to two lateral deviations along retainer ring.Partition has certain angle α to the inboard inclination of bow fork and with level, and 45 °≤α＜90 °, owing to adopt this structure, and the inboard that the angle of partition can guide rubber band deflection bow to pitch, thus be convenient to launch aiming.One end relative position place of retainer ring and partition has opening, owing to adopt this structure, after can be earlier rubber band and skin pocket being connected, rubber band is presented in the retainer ring again, thereby is convenient for changing rubber band, has improved replacing speed.

The specific embodiment

The utility model is described in further detail below in conjunction with Fig. 1:

This cat-eye type catapult is made up of handle 1, bow fork 2, partition 3, rubber band 6 and skin pocket 7, and the inside of pitching the retainer ring 4 of 2 upper ends at bow vertically is fixed with partition 3; Partition 3 can have certain angle α, 45 °≤α＜90 ° to the 2 inboard inclinations of bow fork and with level; Retainer ring 4 can have opening 5 with an end relative position place of partition 3.Because bow is pitched the inside of the retainer ring 4 of 2 upper ends and vertically is fixed with partition 3, partition 3 can be separated two rubber bands 6, thereby prevent to launch back rubber band 6 the situation generation that strength is twined takes place to twist; When finishing when launching, only need rubber band 6 is retracted and can launch next time, wrapping phenomena can not take place in rubber band 6, launches frequency thereby effectively improved; Simultaneously, partition 3 can play the effect of fixed position to rubber band 6, thus when preventing that rubber band 6 is tightened up because the instability of direction of pull and precision is launched in, influence sliding to two lateral deviations along retainer ring 4.Partition 3 tilts and with level certain angle α is arranged to bow fork 2 is inboard, and 45 °≤α＜90 °, owing to adopt this structure, the angle of partition 3 can guide the inboard of rubber band 6 deflection bow forks 2, thereby is convenient to launch aiming.Retainer ring 4 has opening 5 with an end relative position place of partition 3, owing to adopt this structure, after can earlier rubber band 6 and skin pocket 7 being connected, rubber band 6 is presented in the retainer ring 4 again, thereby is convenient for changing rubber band 6, has improved replacing speed.

Claims

1, a kind of cat-eye type catapult, it comprises handle (1) and bow fork (2), it is characterized in that: the inside of the retainer ring (4) on bow fork (2) vertically is fixed with partition (3).

2, a kind of cat-eye type catapult according to claim 1 is characterized in that: described partition (3) has certain angle α, 45 °≤α＜90 ° to the inboard inclination of bow fork (2) and with level.
