handle to be fixedly connected with the
handle, the other end of the main rod is provided with a connection bend, one end of the thread rod penetrates into a through hole formed in the three-claw chuck and then is connected with the connection bend, the other end of the thread rod is connected with a center shaft of the three-fork rod, one end of each connection rodis hinged to the side of the three-claw chuck, the other end of each connection rod is hinged to a clamping rod, and the ends of the clamping rods are provided with clamping blocks. A
bottle cap is clamped by means of cooperated use of the three-claw chuck, the thread rod, the three-fork rod, the connection rods, the clamping rods and a nut, then, the
bottle cap is removed by operating the handle,operation is convenient and saves labor, the opening and closing angle of the clamping rods can be adjusted for bottle caps with different diameters, the problem that universality is poor in the prior art is solved, and the three-claw chuck
bottle cap loosening device has the advantages of being simple in structure, large in adjusting range and easy and convenient to use.
