FIG. 2 is a detailed view of the fixing means 13 for the upper member 11 and the lower member 12 shown in FIG. 1, and the upper member 11 and the lower member 12 constituting the main body 1 of the mortar fixing tool are fixed by the fixing means 13. Indicates the state. In FIG. 2, the upper member 11 and the lower member 12 which comprise the main body 1 are fixed as follows.

  That is, the main body 1 of the mortar fixing tool is placed on a work table, for example, a table, and the base 2 is laid on the inner bottom thereof. The lower opening anti-slip material 12 a of the lower member 12 of the main body 1 is placed on the table surface together with the lower anti-slip material of the base 2.

  Then, the fixing means 13 is loosened, the bowl 3 is accommodated inside the main body 1, and the upper member 11 of the main body 1 is slid on its upper opening while the thread bottom 32 is placed on the anti-slip material 21 on the base 2. The stopper 11a is moved up and down so as to contact the side wall of the bowl 3. The fixing means 13 is tightened and fixed in a state where the upper opening slip prevention material 11a is correctly brought into contact with the side wall of the bowl 3. As described above, this contact position is the position of the wall 33 in FIG. 1 or a position above it.

FIG. 3 is a plan view of the main part for explaining the vertical adjustment structure of the fixing means 13 for the upper member 11 and the lower member 12 constituting the bowl-shaped fixture according to the first embodiment of the present invention. A vertical groove 13d is formed in the upper member 11 of the main body 1 of the bowling fixture, and a bolt screw 13b is inserted into the vertical groove 13d so as to be movable up and down in the vertical groove. The bolt screw 13b is fixed by being screwed into a screw hole of a knob 13c inserted from the lower member 12 side.

Can be stretched vertically. The knob 13c is rotated in the direction of the arrow F in a state where the upper opening anti-slip material of the upper member 11 is in close contact with the side wall of the bowl 3 and fixed. In this state, put the ingredients in the mortar and perform the required work.

  5 and 6 are schematic diagrams for explaining the effect of the first embodiment of the mortar fixing device according to the present invention. In FIG. 5, the mortar 3 is placed on the pedestal 2 of the mortar fixing tool, and is fixedly held by the main body 1. As described above, the position (horizontal line L) where the bowl 3 and the upper opening anti-slip material 11a contact is preferably as close as possible to the open end of the bowl 3 and the position of the upper end of the slide wall 33 in FIG. Try to be in a higher position. If the position where the mortar 3 and the upper opening anti-slip material 11a are in contact with each other is below the horizontal line L, the mortar will not be inclined and the grouting operation will not be disabled.

  In FIG. 5, for example, a case is assumed where the work is performed with a not-shown firewood tree. Here, when the flour tree applies the force indicated by the arrow F1 in the figure below the horizontal line L on the inner wall of the mortar 3, one of the forces F2 is the table surface of the lower opening anti-slip material 12 a of the main body 1. To. Due to the frictional resistance between the lower opening anti-slip material 12a and the table surface, a force -F3 is generated against this force F2.

  Further, the force F <b> 1 by the firewood is applied to the thread bottom 32 of the mortar 3 as another force F <b> 4. For this force F4, a force -F5 that opposes the force F4 is generated by the frictional resistance between the thread bottom 32 of the twister 3 and the base 2. This force -F5 is not dragged directly by the force F2 applied to the main body 1 because the pedestal 2 is independent of the main body 1, and more effective drag against the force F4 than that in which the pedestal and the main body are integrated. It acts to suppress the movement of the mortar.

  Thus, the movement of the mortar 3 due to the force F1 applied to the inner wall of the mortar is suppressed by the structure of this embodiment. The moving force (F2 + F4) that acts on the table surface in the horizontal direction due to the force F1 does not cause the mortar to move horizontally unless the absolute value (F3 + F5) of the force against the force is exceeded. For that purpose, as the lower opening anti-slip material attached to the main body, the upper anti-slip material 21 and the lower anti-slip material 22 of the pedestal 2, there are a large number of protrusions, or a rubber plate, a resin plate, etc., which has been subjected to anti-slip treatment by roughing the surface. Use.

  In the present embodiment, as the pedestal 2, the upper anti-slip material 21 and the lower anti-slip material 22 are attached to the front and back of the substrate 2 of a resin plate, a wooden plate, or a metal plate, but the present invention is not limited to this. The upper anti-slip material 21 and the lower anti-slip material 22 can be directly bonded together, or the anti-slip treatment can be performed on the front and back of a single anti-slip plate. The lower slip prevention material 22 is preferably an elastic material including the upper opening slip prevention material 11a and the lower opening slip prevention material 12a of the main body 1.

  Also, FIG. 6 illustrates the case of using the low-profile mortar 3. If the height of the mortar is slightly different due to replacement of the mortar, the height of the mortar 3 The upper member 11 of the main body 1 is fixed at a position lowered with respect to the lower member in accordance with the height. The action of the force in such a case is the same as in FIG. In addition, when the height of the newly purchased mortar is taller than the previous mortar, the upper member 11 of the main body 1 is fixed at a position raised with respect to the lower member 12, contrary to the above.

  According to the present embodiment, the pot-fixing fixture that makes it easy for the potting work alone by suppressing the tilting force and the lateral movement force applied to the inner wall of the pot in the potting work using the pot. Can be provided.
