Abstract:
1. An improvement for elongate tools that are designed to engage objects from remote distances and that have engagement elements located on a distal end of a rod, a handle on a proximate end of said rod, a controller on said handle to control said engagement elements, and a linkage between said controller and said engagement elements to control said engagement elements, said controller further comprises a trigger member and said trigger member is attached to said handle, said improvement comprising a lock member, said lock member comprising a receiving surface and a stop member, said receiving surface extending from said trigger member and adapted to receive said stop member, and said receiving surface attached to said trigger member in a rigid and fixed relationship, wherein said receiving surface comprises a series of adjacent saw-tooth shaped extensions and said stop member comprises at least one opposite complementary saw-tooth extension wherein when said extension from said stop member engages said receiving surface, said receiving surface is restricted from lateral movement with respect to said stop member thereby causing said trigger member to lock said lock member further comprising a switch member, said switch member connected to said stop member to control the movement of said stop member, wherein in response to movement of said switch member, said stop member either engages or disengages said receiving surface wherein when said stop member is engaged with said receiving surface the movement of said trigger member is prevented and when said stop member is disengaged from said receiving surface said trigger member is allowed to be displaced.
