A tool for cracking ice and frost includes an outer tubular member, a T-shaped handle fixedly mounted on an upper end of the outer tubular member, a cylindrical sleeve having an axial through hole and an end formed with a flange, a conical head having a conical portion at one end thereof, a neck portion adjacent to the conical portion and a threaded portion at another end thereof, an inner tubular member being formed an internally threaded portion at one end thereof, an externally threaded portion at another end thereof, and an inner neck portion at an intermediate portion thereof, a striking pin provided with a sharp point at a lower end thereof and a flange at an upper end thereof, a guiding pin formed a cylindrical portion, an enlarged bottom at a lower end thereof, a rod portion having a smaller diameter than said cylindrical portion, and a conical portion between the cylindrical portion and the rod portion, a first helical spring provided with an eccentric lower end and arranged between the inner neck portion of the inner tubular member and the enlarged bottom of the guiding pin, a cylindrical hammer formed with an axial blind hole at a bottom thereof, a second helical spring being fitted within the inner tubular member, and a cap threadedly engaged with the upper end of the inner tubular member.
A tool for holding and installing clip-on type wheel balancing weights to be affixed to pneumatic automobile and truck tire rims is provided. The tool may be used to quickly, conveniently, accurately, permanently and painlessly install clip-on type wheel weights, from the largest available to the smallest desirable, for precision balancing of automotive tires.
A glass tapping tool for tapping glass and breaking glass along a score-line that has been previously cut. In one embodiment, the tool comprises a hollow tube with a first end and a second end. A stationary striking member is attached to the first end of the tube for tapping a piece of glass which has been previously cut along a score-line. Mounted inside the tube is a slidable hammer with a first end and a second end. The slidable hammer is mounted so that the second end of the slidable hammer protrudes outside the second end of the hollow tube. Elastically coupled the stationary striking member with the slidable hammer is a spring. When a user pulls the part of slidable hammer protruding from the hollow tube in an axial direction away from the hollow tube, the spring produces a force in opposite direction which causes the slidable hammer through the spring to strike the stationary striking member, when the user releases the slidable hammer, so as to tap the glass along a score line and causing the glass to break along the score line.
