Abstract: An axillary crutch is disclosed in the invention; the axillary crutch has a body comprised of two opposite shafts, each shaft has a wall portion embedded therein, so that the wall portions may serve as the basis for adjusting and positioning a handgrip. Therefore, the shafts do not need to be formed with holes for securing the handgrip, which not only maintains the strength of the shafts, but also reinforces the strength and security of the axillary crutch as a whole because the shafts are embedded with fortified wall portions therein. Moreover, the position of the handgrip may be adjusted according to the length of a user's arm, and a pivot fitted into the handgrip may hold the opposite shafts together, which prevents the two shafts from becoming deformed or twisted, or buckling due to external forces.

Abstract: A crutch comprises a pad enclosing an arm piece, two bow rods connecting the hollow arm piece longitudinally, a handpiece connecting two bow rods transversely, a pipe clamped by the lower portions of two bow rods, an extensible rod inserted beneath the pipe, a tip cushion covering the lower end of the extensible rod, and a mount confining the lower ends of the pipe and two bow rods. A plug is disposed on the upper end of the pipe. The pipe has a plurality of adjusting holes.

Abstract: A folding play crib structure comprising frame tubes, corner joints, middle joints, central bottom joint, U-shaped tubes, V-shaped pull rods, bottom cross tubes and leg joints. One end of the frame tube is pivotally connected with an insert seat which cooperates with the joints for controlling the locking and folding of the crib structure. The U-shaped tubes are pivotally connected at the central portion of the bottom cross tubes to enhance the supporting effect for the bottom of the crib structure. V-shaped pull levers are pivotally connected on one side of the U-shaped tube, whereby when folding the cross tubes, the U-shaped tubes are also folded to ensure safety and more reliably support the crib structure at multiple points of the bottom thereof.

Abstract: A golf cart comprising a handle, an upper tube, a middle tube, an upper cover for the middle tube, a lower tube, an upper cover for the lower tube, an upper bracket, a lower bracket having a support base, a lower cover for the lower tube, a rocking butterfly plate, a rocking slide block, a link assembly and cart wheels, wherein the handle is fixed on an upper end of the upper tube and the upper, middle and lower tubes are fitted into each other and pressed and fixed by screws. The upper bracket and lower bracket are respectively fitted on the middle tube and lower tube and fixed by eccentric pressing blocks. The rocking butterfly plate is fitted on a rear face of the lower tube and fixed by the eccentric pressing block. The rocking slide block is slidably fitted into the dovetail channel of the lower tube. By means of the cooperation of the V-shaped pull lever and link assembly, with the rocking slide block, the wheel support is foldable.

Abstract: A telescopic and foldable crutch structure includes an armpit seat, two telescopic inner tubes each having a top end on which the armpit seat is disposed, two telescopic outer tubes telescopically receiving the inner tubes, a handle adjustably coupling the telescopic inner and outer tubes with each other, a locking cam having a locking pin, two coupling blocks, two outer coupling tubes, an adjusting outer tube, an adjusting inner tube, a cap member fitted on bottom ends of the outer coupling tubes and the adjusting outer tube and a pad member fitted on a bottom end of the adjusting inner. The adjusting outer tube is tightened by the locking cam, The adjusting outer tube, is pivotally connected with the telescopic outer tubes by the locking pin and tightened between the telescopic outer tubes by the locking cam. The locking cam is adapted to be pulled upward, permitting the adjusting outer tube and the outer coupling tubes to be folded upward.
