crocodile fork

Abstract

The invention discloses a crocodile fork, which is composed of an upper fork, a movable fork, a fixed fork, a lower fork, two independent cones, two independent gear racks, a torsional spring and a stopper; the crocodile fork is characterized in that the tail end of the movable fork is connected to a square solid body of the fixed fork by virtue of a pin, and the movable fork can move in a fan-shaped form; an included angle is formed between the movable fork and the fixed fork; the gear racks are each arranged at the bottom of a groove of each fork; two cones are arranged on a same shaft and are meshed with the corresponding gear racks; and the stopper is screwed at two ends of a shaft head. The stopper is pushed forwards by an athlete's finger, so that the cone on the movable fork can rotate in a clockwise direction and the cone on the fixed fork, which can take a damping effect, can rotate in an anticlockwise direction, the included angle between the two forks is minimized and the upper fork which is arranged on the movable fork is descended to the lowest position; the included angle between the fixed fork and the movable fork is maximized and the upper fork is ascended to the highest position when the stopper is pulled backwards by a hand; the upper fork, which moves from the lowest position to the highest position in a mode of stepless regulation, can have a plurality of rest points, so that functions are enriched in comparison with current low, middle and high rest points, more choices are offered to an athlete and the possibility of winning is improved; and the crocodile fork is simple to make, low in cost, economical and practical.

Description

Technical field: [0001] The invention belongs to the technical field of billiard stand manufacture, and in particular relates to a billiard stand with a crocodile fork capable of steplessly adjusting the height of the upper fork. Background technique: [0002] As far as I know, billiards is one of the sports activities that exist widely all over the world. It is popular in Europe and the United States. Now there are more and more young people and people who love billiards in our country.

The rule of the billiards game is that the player hits the white ball with a cue using various brackets as the fulcrum, hits the colored ball, and makes the colored ball enter each hole near the library to score. Players A and B who score more colored balls and accumulate more po...

AI Technical Summary

Problems solved by technology

Players A and B who score more colored balls and accumulate more points are the winners. Usually the players use their fingers as the fulcrum to hit the white ball with a club, but many colored balls have ever-changing positions on the table. There are colored balls blocking the position of the pole. If you want the best position for the pole, you need to use special tools as the fulcrum. There are three types of poles commonly used, low poles, middle poles, and high poles. Their styles There are many, such as fancy forks, English forks, American forks, cross forks, antler forks, elephant trunk forks, butterfly forks, bat forks, etc. No matter what kind of fork is, the height of the three dimensions of low, medium and high is fixed. People want to be more precise, and there is still no pole with a fourth height. For example, it cannot be realized at any point between the low pole and the high pole, and it cannot be achieved at any point higher than the high pole. This is the current situation. The unsatisfactory parts of the three poles require us to create and develop more accurate multi-point height poles to provide athletes with handy crocodile forks.
