Pull rod fork with stepless adjustable height of double lower support legs

Abstract

The invention discloses a pull rod fork with stepless adjustable height of double lower support legs. The pull rod fork consists of an upper fork, a cross beam, pull rods, a handle seat, a rotary column and a handle. The pull rod fork is characterized in that the upper fork is manufactured into two cylinders which are perpendicular to each other, and the lower ends of the two cylinders are connected integrally, and the connecting place is also integrally connected with the cross beam; the cross beam is a cuboid; the handle seat is arranged in the middle of the side surface of the cross beam; through holes are formed in two ends of the side surface of the cross beam respectively and the through holes can penetrate through the rotary column; a hole is formed in a relatively thick section of the rotary column, and the hole can penetrate through the thickest section of multiple sections of the pull rods; after half of the section of the pull rod is penetrated, the pull rod and the circular hole in the rotary column are firmly glued through a strong binder; in installation, after a thin section of the rotary column penetrates through the circular hole in the cross beam, a spring spacer is placed and then a pin is adopted in a penetration manner, so that the length of a frame bar can be changed by an athlete by freely pulling the movable parts of the pull rods manually when the height of the frame bar needs to be adjusted; the corresponding pull rods also can rotate left and right so as to take advantage in motion; and the universal frame bar is creative in design, simple in manufacturing, low in cost and high in market prospect.

Description

AI Technical Summary

Problems solved by technology

Players A and B who score more colored balls and accumulate more points are the winners. Usually athletes use their fingers as the fulcrum to hit the white ball with a cue, 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 the fourth height. For example, it cannot be realized at any point between the low pole and the high pole, and it cannot be realized at a higher pole 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 a handy billiard pole fork with stepless adjustable double lower legs height
