Description

[Detailed description of the invention] The present invention relates to a convenient long press holding tool that can temporarily hold the long press when attaching the long press to a lintel, or hold it for a desired time when gluing. , its configuration will be described in detail with reference to the accompanying drawings as follows.

A screw rod 4 having a U-shaped locking rod 3 that fits into the long press 1 from above and locks on the back side nailing step 2 of the long press 1.
A guide tube 7 with a presser plate 6 that presses the lower surface of the lintel 5 is fitted loosely into the tip of the U-shaped locking rod 3 so as to be able to move up and down, and a grip handle 8 is attached to the end of the threaded rod 4. is screwed onto the guide cylinder 7, and a rotation prevention mechanism a is provided at a suitable position on the guide cylinder 7 to prevent rotation of the guide cylinder 7 itself in the axial direction. In the rotation prevention mechanism a shown in the drawing, a guide groove 9 is formed in the length direction at one location of the screw rod 4, and a ball storage hole 10 is bored at one location of the guide cylinder 7, and a guide groove 9 is formed in one location of the guide cylinder 7. The figure shows a case where a ball 11 partially engaged with the groove 9 is stored and the ball 11 is pressed from the outside with a C-shaped pressing spring 12.

In the figure, 13 is a ball holding recess, and 14 is a stopper. Since the present invention is constructed as described above, the second
As shown in the figure, press the U-shaped locking rod 3 from above the long press 1.
and press and hold the tip of this U-shaped locking rod 3.
The grip handle 8 is rotated and tightened until the holding plate 6 strongly presses the lower surface of the lintel 5, thereby connecting the tip of the U-shaped locking rod 3 with the holding handle. The long press 1 and the lintel 5 are fixed by the pressing force with the plate 6, that is, the clamping force.

In this way, the long press 1 can be temporarily secured to the lintel 5 simply by rotating and tightening the grip handle 8. (In the case of adhering the long press 1 and the lintel 5, the adhesion state is maintained for a desired time.) When the grip handle 8 is rotated and tightened, the tip of the grip handle 8 is attached to the guide cylinder 7. Since the guide tube 7 is pressed against the lower surface, it may rotate together with the guide tube 7. When the guide tube 7 rotates, the position of the holding plate 6 shifts and the tip of the U-shaped locking rod 3 no longer corresponds to the U-shaped locking rod 3. Locking rod 3
There was a drawback that the long press 1 and the lintel 5 could not be held down by the tip of the button and the holding plate 6.

Therefore, in order to make the tip of the U-shaped locking rod 3 correspond to the presser plate 6, it is necessary to rotate the grip handle 8 with one hand and press the guide tube 7 with the other hand while working. I had to do it, and it was troublesome.

In this regard, in the present invention, the guide cylinder 7 is provided with a rotation prevention mechanism a that prevents rotation, so that the guide cylinder 7 can rise while corresponding to the tip of the U-shaped locking rod 3 without rotating. This allows the user to work with one hand without having to hold down the guide tube 7 one by one. In addition, since there is enough distance between the tip of the U-shaped locking rod 3 and the grip handle 8 to allow a hand to fit in, the grip handle 8 can be gripped without hitting the wall with the hand. It has excellent practical effects, such as being easy to make and work with.

Claims (1)

[Scope of utility model registration request] An inverted U-shaped locking rod is attached to the tip of the threaded rod from above and is engaged with the nailing step on the back side of the long pressing. A guide tube with a presser plate that corresponds to the tip of the rod and presses the underside of the lintel is loosely fitted so that it can be raised and lowered freely, a grip handle is screwed onto the end of this threaded rod, and the guide tube is inserted into the appropriate position of the guide tube. A long pressing tool characterized by being equipped with a rotation prevention mechanism that prevents rotation in the axial direction of the holding tool.
