detailed description

Below in conjunction with accompanying drawing, describe the utility model in detail.

The multi-functional compound tool fixture shown in Figure 1-3 includes a lower clamp body 1, an upper clamp body 2, a gasket 3, a first stud 4, a first operating handle 5, a butterfly nut 6, and a second operating handle 7 and the second stud 8, the above parts are independent of each other and can be freely disassembled and assembled.

The lower clamping body 1 and the upper clamping body 2 jointly form a clamping body structure, which controls the size and position of the clamping and clamping, and performs adjustment, positioning, fastening and specific processing of small workpieces (sheet materials, round materials). The lower clamp body 1 and the upper clamp body 2 have opposite abutting surfaces for clamping workpieces. The front butt joint surfaces of the lower clamp body 1 and the upper clamp body 2 are provided with notches 9. When they cooperate with each other, the two notches 9 jointly form a clamping groove for fixing the workpiece. Preferably, when the lower clamping body 1 and the upper clamping body 2 are closed together, the two notches 9 jointly form a square clamping groove, and the square design can more firmly clamp such as round rods, Workpieces with special shapes such as thin plates.

Both the outer surfaces of the first stud 4 and the second stud 8 are threaded, and together form an adjustment structure. A vertical first through hole 10 is provided in the middle of the lower clamp body 1, and a vertical second through hole 11 is provided in the middle of the upper clamp body 2, and the first through hole 10 and the second through hole 11 are coaxially arranged. The bottom of the first stud 4 is sequentially inserted into the second through hole 11 and the first through hole 10, wherein the inner wall of the first through hole 10 is provided with an internal thread adapted to the external thread of the first stud 4, so that the first through hole The bottom of a stud 4 can be effectively fixed, and the second through hole 11 has a smooth inner wall and is larger in diameter than the first through hole 10, so that the upper clamp body 2 can move vertically on the first stud 4, thereby adjusting the lower clamp body 1 and the distance between the upper clamp body 2. The wing nut 6 is sleeved on the first stud 4, the internal thread of the wing nut 6 is compatible with the external thread of the first stud 4, and the gasket 3 is installed under the wing nut 6, by tightening and loosening Wing nut 6, so as to realize the clamping and releasing of the workpiece. The first operating handle 5 is screw-fixed on the top end of the first stud 4 , and the first stud 4 can be freely tightened and unscrewed by operating the first operating handle 5 .

The rear portion of the upper clamping body 2 is provided with a vertical third through hole 12, the bottom of the second stud 8 is inserted into the third through hole 12, and the inner wall of the third through hole 12 is provided with an external thread suitable for the second stud 8. The internal thread of the matching, so as to realize the fixing of the second stud 8, the bottom end of the second stud 8 passes through the third through hole 12 and presses against the butt surface of the lower clamp body 1, on the one hand, it can strengthen the upper clamp The stability of the concrete 2 prevents it from rotating around the first stud 4; on the other hand, because the workpiece is clamped at the front of the lower clamp body 1 and the upper clamp body 2, the force is uneven, and in practice The lower clamping body 1 and the upper clamping body 2 are prone to inclination during operation, and the parallel distance between the lower clamping body 1 and the upper clamping body 2 can be effectively adjusted through the supporting and pressing effect of the second stud 8 to keep them parallel. Improve overall stability. The second operating handle 7 is screw-fixed on the top of the second stud 8 , and the second stud 8 can be freely screwed and unscrewed by operating the second operating handle 7 .

When using the clamping function of the present invention, first loosen the lower clamp body 1 and the upper clamp body 2, place the workpiece between the draw-in slots formed by the lower clamp body 1 and the upper clamp body 2, and then tighten the wing nut 6 , and then tighten the second stud 8 to adjust the distance between the lower clamp body 1 and the upper clamp body 2 to keep it parallel and stable.

In addition to the clamping function, the present invention also combines the functions of various other tools, and can be used as a dismounting tool in conjunction with tools such as a straight lifter and a cross lifter. After the fixture is disassembled, it can be used as a hand hammer, and a plurality of inner hexagonal holes 13 are symmetrically arranged on the left and right sides of the lower clamp body 1. The plurality of inner hexagonal holes 13 have various common sizes and can be assembled and disassembled. Bolts, nuts and hexagon socket screws, the first stud 4 and the hexagon socket hole 13 are used in conjunction, and the principle of leverage is used to make disassembly and assembly more labor-saving. As shown in Figure 2, the front side of the lower clamping body 1 is also provided with a scale 14, which can be used as a reference size when clamping a workpiece, and can also be used as a measuring ruler alone. Referring further to Fig. 4, the front end of the lower clamp body 1 is provided with a V-shaped notch 15, which can be used as a nail remover.
