Description
Technical field
The utility model relates to the technological improvement to traditional catapult and vehicle escape hammer, especially multi-functional elastic presss from both sides clockwork spring
The device of catapult, more specifically, it relates to which a kind of multi-functional elastic presss from both sides clockwork spring catapult.
Background technique
Currently, there is the shortcomings that cannot recycling elastic automatically, bullet is mutually separated with catapult in traditional catapult, so that rubber after transmitting
Muscle random coil turns round circle, it is necessary to and both hands operation could complete that elastic is cleared up neatly and bullet installs the process of transmitting, cumbersome,
Inefficiency, moreover, loose elastic is exposed to outside, it has not been convenient to daily preservation and carrying.Furthermore there is circle elastic in traditional catapult
With the classification and cumbersome binding problem of flat elastic, it cannot accomplish that round flat elastic is general and exempts to bind.Meanwhile on the market
Vehicle escape hammer exists to be limited by user's arm length, can only hammer the glass for vehicle window nearest apart from oneself, and optimal broken
Window position should be the glass for vehicle window farthest apart from oneself, for example, driver smashes the right window of back seat by taking five overboard automobiles as an example
Glass is most advantageous to escaping, because water comes in that steering position region air can be compressed in from right back, has both won sufficiently
Enabling pressure can also win breathing space to greatest extent, avoid and smash driver master and drive glass, flood comes head-on
Unsafe condition.But traditional life-saving hamer is short and small, driver can not smash the rear farthest apart from oneself on driver's seat with it
Again small by operating space with traditional catapult to glass, elastic, which arranges winding, to be unfolded, and bullet finds the disadvantages of difficult, and
Multi-functional elastic folder clockwork spring catapult can overcome disadvantage mentioned above completely, and life-saving hamer and catapult are integrated by innovation, become conjunction
Suitable Sporting toy and escaping tool.
How allowing traditional catapult to have, elastic recycling is neat, and bullet is rapid on bullet, does not choose elastic, round flat it is general and also from
How binding, avoid the weakness of vehicle escape hammer, and do not limited by interior small space, can arbitrarily smash the vehicle of any one side
Window, moreover, the production cost for completing above-mentioned design not will cause price again below or near the cost of common catapult on the market
It is excessively high, to solve these puzzlements, appeal for a long time in society.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide it is a kind of low cost, can elastic recycling,
Ball singlehanded can be shot, round flat elastic is not chosen, the multi-functional elastic that vehicle escape hammer uses can be done from elastic binding, multi-purpose content
