| 摘要 |
A device is provided for locking a front end of a shaft for a spear gun. The device comprises a bridge-shaped element extending crosswise over a distal end of the gun with a substantially U-shaped nosepiece connected to the distal end and revolving relatively freely about a crosswise axis thereof. The nosepiece includes at least two arms connected respectively to ends of a relatively elastic cable that may be tensioned against a rear end of the shaft, when the shaft is placed on a support surface along the body of the gun. The bridge element is attached to and integrally with the ends of the elastic cable and is placed at a selected distance from the support surface such that the shaft is retained against the surface when the spear is in a stowed or loaded position in the gun.
