Problems solved by technology

[0005] However, if the sponge 106 is used for a long time, the recovery performance will be reduced, and the front end of the sponge 106 cannot fully touch the head of the bolt or the nut.
That is, the durability performance is reduced
In addition, it is necessary to replenish the coloring liquid from the injection port 107 at any time, but if the injection port 107 is small, it is difficult to replenish the coloring liquid, and it takes time and effort to replenish.
If the injection port 107 is enlarged for easy replenishment, it is easy to reverse the coloring liquid from the injection port 107

Embodiment Construction

[0023] As shown in FIG. 1 , the bolt fastening device 10 is composed of a socket wrench 20 and a coloring solution supply mechanism 40 .

[0024] The socket wrench 20 is composed of a rod 21 , a torque meter 22 provided at one end of the rod 21 , a socket 23 provided on the torque meter 22 , and a handle 24 provided at the other end of the rod 21 . The coloring liquid supply mechanism 40 is provided with a valve mechanism 41 , and the sleeve 23 can be fitted into a hexagonal columnar liquid outlet pipe 49 provided on the valve mechanism 41 . That is, the discharge pipe 49 is formed in a shape similar to a head of a bolt or a nut.

[0025] The sleeve 23 and the coloring liquid supply mechanism 40 will be described in detail below.

[0026] As shown in Figure 2, a large recess 25 is provided on the sleeve 23, and the inlet portion of the large recess 25 becomes the head of the bolt 38 (Figure 3A), the nut 39 (Figure 3A) or the outlet pipe 49 (Figure 1 ) into the fitting portio...

Abstract

A fastening means of bolt and or nut screw can distinguish the bolt and or nut screw finishing the fastening operation and the bolt and or nut screw incompleting the fastening operation. The apparatus (10) has a box spanner (20) and a dye liquid holding part (40). The supplement of the dye liquid is processed through interlocking the sleeve (23) arranged on the box spanner (20) and the filtrate pipe (49) arranged on the dye liquid holding part (40).

Description

technical field [0001] The present invention relates to a bolt or nut fastening device, which operates on a plurality of bolts or nuts and has the function of distinguishing bolts or nuts that have been fastened from those that have not been fastened. Background technique [0002] If the number of bolts and nuts to be tightened increases, it will be difficult to know whether they have been tightened or not, and the tightening will be insufficient, which is not desirable. Alternatively, retightening already tightened bolts or nuts will result in prolongation of operation time. As a countermeasure against this, for example, a special socket wrench is disclosed in Japanese Unexamined Publication No. 60-161569. Such a special box wrench will be described based on FIG. 8 . [0003] As shown in Figure 8, the special socket wrench 100 comprises a rod 101, a shaft 102 extending from one end of the rod 101, a sleeve 104 fixed on the shaft 102 by a small screw 103, a sleeve 104 fixe...
