DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-direction chuck wrench (CHUCK WRENCH) used as a kind of scissors.

[0002]

2. Description of the Related Art A generally used plate chuck wrench operates a number of chucks to collect adjacent plate members, and a chuck wrench is provided for each unit on one side of the upper and lower sides of the object to be sandwiched. It is only available, and therefore there is the inconvenience of having to prepare multiple sets of chuck wrenches. That is, with only a single set of chuck wrenches, when the object to be sandwiched is firmly sandwiched, one side of the object to be sandwiched is lifted and the object cannot be effectively sandwiched.

[0003]

In this case, if the upper and lower sides are to be equally sandwiched, it is necessary to simultaneously sandwich the upper and lower sides by using two or more sets of chucks. However, when the length of the object to be sandwiched is relatively long, a large number of chucks must be operated, which is inconvenient in operation and uneconomical in terms of cost.

SUMMARY OF THE INVENTION The present invention is an improvement in the structure of the front chuck head and the rear chuck sheet found in conventional scissors. That is, the present invention comprises a front chuck head 1, a rear chuck sheet 2, an upper pressure plate 3, a lower pressure plate 4 and two sets of tightening pedestals 8 and 9. The front chuck head 1 has two side plates 11 and a lower stopper. The shaft 12 and the central plug shaft 13 are integrally connected to each other, and the central plug shaft 13 is screwed with a screw plug 14, and a thrust mass 15 is attached to the front end of the screw plug 14.
Has a blade-shaped nut 16 at its end, and the rear chuck sheet 2 also has two side plates 2
1 and a lower stopper shaft 22, and a central stopper shaft 23 is provided with a U-shaped stopper seat 231. The upper and lower pressure plates 3 and 4 are plate-shaped bodies having appropriate thickness and width. , Tightening pedestal 8,
Reference numerals 9 are provided on the upper end portions of the front chuck head 1 and the rear chuck sheet 2, respectively, and the tightening pedestals 8 and 9 are the receiving pedestals 5.
1, the wedge shaft 52, the hook body 53, and the torsion spring 54, and the pedestal 51 is a U-shaped plate-like body that allows the upper pressure plate 3 to pass therethrough and lower plug shafts of the front chuck head 1 and the rear chuck seat 2. It is a multi-directional chuck wrench in which the lower pressure plate 4 is arranged on the plates 12 and 22, and the object 6 can be firmly sandwiched between the upper pressure plate 3 and the lower pressure plate 4.

[0005]

Function: Front chuck head 1 and rear chuck sheet 2
The upper pressure plate 3 is penetrated through the pedestal 51, and the arcuate rough surface 533 of the second end of the hook body 53 is tightly engaged with the upper pressure plate 3 by the twisting force of the torsion spring 54 to generate a coupling effect. . Further, the lower pressure plate 4 is arranged on the lower stopper shafts 22 of the front chuck head 1 and the rear chuck sheet 2, and the object to be sandwiched 6 is placed.
Between the upper pressure plate 3 and the lower pressure plate 4. Thus, when the screw plug 14 is rotated by the nut 16, its thrust mass 15
The object to be sandwiched 16 can be firmly sandwiched between and the stop seat 231. By appropriately pressing the hook body 53 by the pressing portion 532, the engagement between it and the upper pressure plate 3 is released.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the structure of the present invention has a front chuck head (CHUCK HEAD) 1 and a rear chuck sheet (CHUCK HEAD).
K SEAT) 2, an upper pressure plate 3, a lower pressure plate 4 and two sets of tightening pedestals 8 and 9. The front chuck head 1 has two side plates 11, a lower plug shaft 12 and a central plug shaft 13 which are integrally formed and a screw plug 14 is provided on the central plug shaft 13. A thrust mass 15 is fitted on the front end of the screw plug 14, a blade-type nut 16 is screwed on the end, and both side plates 21 of the rear chuck sheet 2 are joined by a lower plug shaft 22. The central stopper shaft 23 is provided with a U-shaped stop seat 231 and is designed to receive an object to be sandwiched.

Besides, the upper pressure plate 3 and the lower pressure plate 4 are both plate-shaped bodies having appropriate thickness and width. In these embodiments, these structures are, that is, the front chuck head 1 and the rear chuck sheet 2 are individually provided with fastening pedestals (see FIGS. 2 and 3). Have the same structure. Therefore, here, the structure of the front chuck head 1 will be slightly described in detail.

As shown in FIG. 2, the tightening pedestal is provided on the upper end of the front chuck head 1 (or the upper end of the rear chuck sheet 2 as shown in FIG. 3). The tightening pedestal is composed of parts such as a pedestal 51, a wedge shaft 52, a hook body 53, and a torsion spring 54. Among them, the pedestal 51 is a U-shaped plate-like body, and connecting holes 511 are formed on both side walls thereof. And an implanting iron piece 512 is provided on one side wall thereof toward the inside.

The wedge shaft 52 is a connecting hole 5 on both side walls of the pedestal 51.
It is provided so that it may penetrate 11, and both side walls are connected by this. The hook body 53 is a plate-shaped hook body having a second-letter shape, the end of the second-letter shape is appropriately arcuate, and the arcuate end surface is a serrated serrated surface 531. Reference numeral 532 is the pressing portion. A connecting part 533 is provided on the Otsuji type hook,
A connecting hole 534 for turning the wedge shaft 52 is formed in the connecting portion 533.

The torsion spring 54 is a rough surface 53 of the hook 53.
3, the wedge shaft 52 is provided so as to penetrate through the connection hole 511 of the pedestal 51 and the connection hole 534 of the hook body 53, and one end of the torsion spring 54 is held by the hook body 53. The other end is held by the implanted iron piece 512 of the pedestal 51.

As described above, the upper pressure plate 3 is fixed at a fixed position by using the hook body 53, and the lower pressure plate 4 is attached to the lower chuck shaft 2 at the lower ends of the front chuck head 1 and the rear chuck sheet 2.
If it is provided so as to penetrate above 2, a space sandwiching the object is formed.

The operation of the multidirectional chuck wrench constructed by the above components will be described. The upper pressing plate 3 is penetrated through the receiving bases 51 of the front chuck head 1 and the rear chuck sheet 2, and the second end-shaped arcuate rough surface 533 of the hook body 53.
Is tightly engaged with the upper pressure plate 3 by the twisting force of the torsion spring 54, and a coupling effect is generated. Further, on the lower stopper shaft 22 of the front chuck head 1 and the rear chuck sheet 2,
The lower pressure plate 4 is arranged and the object 6 is placed between the upper pressure plate 3 and the lower pressure plate 4. Thus, by rotating the screw plug 14 by the nut 16, the object 16 can be firmly sandwiched between the thrust mass 15 and the stop seat 231. Appropriate pressing part 5
By pressing the hook body 53 with 32, the engagement between it and the upper pressure plate 3 is released. Therefore, according to the present invention, it becomes possible to tightly and firmly sandwich a large number of objects to be sandwiched. Further, the present invention is characterized in that it is easy to use and the components are simple.

[0013]

【The invention's effect】

(1) When the work for sandwiching an object to be sandwiched such as a plate material is performed using the multidirectional chuck wrench according to the present invention, the operation can be performed easily and quickly. Further, the fixed pedestal at the bottom of the lower pressure plate can be omitted, and the parts for adjusting the fixed pedestal can also be omitted. In addition, the upper pressure plate can be easily removed and inserted for convenient operation. (2) The present invention is a chuck wrench having a simple structure. When not in use, the upper and lower pressure plates can be removed at any time, and it is not necessary to provide a fixed pedestal on the lower pressure plate, and the fixed pedestal can be adjusted. The necessary parts can be omitted as well, which has the advantage of not occupying an extra space when storing.
