摘要： A foldable frame structure for trailer so designed that the distance between the pivot connection center of each pivot holder and the left/right side frame and the topmost edge of the left/right frame bar of the bottom frame is greater than the distance obtained by deducting the width of the collapsed bottom frame from the height from the left/right frame bar of the bottom frame to the topmost edge of the left/right side frame. Thus, the left side frame and the right side frame can be individually collapsed and closely attached to the bottom frame in one step. The present invention can greatly save the transportation volume and simplify the folding structure and folding action, and thus achieve the purpose of user's convenient collection and carrying.

摘要： A step auto clay thrower consisting of a base, a stepping rod, a support, a throwing arm holder, a throwing arm and a mini motor is disclosed. When the stepping rod is depressed, the throwing arm is forced by a second spring to move a link and a first linking member in turning a shaft and a throwing arm forward for causing generation of a centrifugal force to throw a clay away from the throwing arm, and then a motor shaft of the mini motor is driven to rotate the shaft, thereby returning the throwing arm without any manual operation. In the time the throwing arm throws the clay and the throwing arm is returned by the mini motor, the mini motor does not need to overcome the force of the second spring so that the capacity of the mini motor can be minimized.

摘要： A bipod base consisting of a rail clamp, a first quick-release, a ball joint, first and housing clamps, first and second spherical bushings and a second quick-release. When the second quick-release is loosened, the rail clamp is allowed for 360-degree angular position adjustment with the ball of the ball joint relative to the first and second spherical bushings and the first and second housing clamps. After adjustment, the second quick release handle is biased to fasten tight the first and second housing clamps in locking the first and second spherical bushings that are kept in surface contact with the ball of the ball joint.

摘要： A trap wobbler includes a base with an inclined bearing seat and a bearing supported on the inclined bearing seat, a trap frame connector pivotally coupled to the bearing of the base for enabling the trap frame connector to be biased relative to the base, and a throwing trap fastened to the trap frame connector. When the throwing arm of the throwing trap is rotated to throw a clay, the inertia force thus generated causes the throwing trap and the trap frame connector to swing left and right. As long as the throwing arm is continuously controlled to continue throwing a clay before stopping of the swinging action of the throwing trap, the left and right swinging motions and amplitudes of the throwing trap is continuously increased.

摘要： An easy fold layout hunting blind framework structure comprises two upper supporting frames, two side supporting frames, and four supporting feet. When folding, four supporting feet can be folded towards four foot stocks, and two side supporting frames can turn downwards to come close to each other, and two upper supporting frames can be folded towards the two side supporting frames and, thus, the operation is easy. On the other hand, when developing for use, the only thing to do is to develop two side supporting frames, and develop four supporting feet, when turning both upper supporting frames so as to make their straight portions closely press each other thereby completing the developing operation. The operation is simple without using hand tools or detaching any component parts.
