Claims

[Scope of utility model registration request]

(1) Consisting of a long handle, a pipe clamp part provided at the lower end of the handle, and a clamp operating part that reaches from near the upper end of the former to the latter, and the handle is attached to a groove in which a pipe for underground piping is laid. The main part is a cylindrical handle that is considerably longer than the depth of the pipe, and grip handles are provided at two upper and lower positions, respectively. Has a clamp claw,
The portions of these claws below the pivot points are opposed to each other in a substantially ( ) shape, and on the inside of the portions above these points, slopes are formed that face each other in a V-shape, and the clamp operating portion The above-mentioned operating handles are respectively pivotally supported at two positions above and below the body, a wedge which is fitted into the lower end of the handle so as to be able to rise and fall and narrows downward into a ■-shape; It has a spring that presses the wedge in the direction of pushing the wedge into the opposing diagonals of the clamp claws, and each of the upper operation handles and the wedge at the lower end are connected by an interlocking medium housed inside the handle. Pipe grip and placement for buried piping characterized by:

(2) Each operating handle, which is engaged with the interlocking medium inside the handle by a fork at the tip, is pivoted to the handle at a position slightly in front of each fork, and can only be moved downward from a horizontal position. A pipe gripping device for buried piping as set forth in claim 1 of the utility model registration claim, characterized in that it is rotatable.

(3) A lock pin whose lower end protrudes from both sides of the V-shape of the model when it descends relative to the wedge passes through the wedge in a movable manner and faces the V-shape of both clamp claws. A recess is formed at the bottom of each inclined surface to engage the lower end portion of the lowered lock pin, the lock pin is connected to the interlocking medium inside the handle, and the wedge is connected to this interlocking medium. The locking pin is shaped so that it is locked onto the shoulder of the upper end of the locking pin when it rises without falling, and the locking pin and wedge are each individually pressed downward by a dedicated spring. A pipe gripping device for buried piping as set forth in claim 1 of the utility model registration claim.
