Abstract

The utility model relates to a hinge hand frame, which is composed of clamping blocks with handles, wherein, the two clamping blocks are connected together by adjusting screws, and approximate ellipse assembling grooves are arranged on the two clamping blocks. Fastening screws are arranged on the side walls of the curved surfaces of the grooves. The utility model is also provided with two tap clamping blocks, just uses a frame to install dies, taps and reaming tools with different kind and different specifications to realize a plurality of functions of threading, tapping and reaming. The utility model has the advantages of multiple functions, material saving, portability and convenient operation.

Description

General die

The utility model is a kind of hand bracket, particularly can finish the general hand bracket of multiple function.

Now people are with screw die, screw tap, the manual hitch of reamer, tapping, fraising the time, generally are model specifications with a shelf, thus need make a lot of shelfs, the expense of both having taken a lot of work material, and use and carry also inconvenience.

The utility model aims to provide a kind ofly can be installed variety classes, different size screw die, screw tap, reamer and finish the ream general hand bracket of multiple function of hitch, tapping.

The purpose of this utility model is achieved in that it comprises two clamp 1 and clamps 6 that can be adjacent to its side plane, be screwed with on the clamp and two clamps are combined as a whole and can adjust the adjustment screw of distance between two clamps, have the smaller part circular groove on two clamps, when being adjacent to, it forms the vertical frock groove 10 of sub-elliptical shape, groove is equipped with 3-5 adjustable fastening jackscrew that is screwed into from the clamp another side on the bent side, bottom portion of groove is the plane that the center has circular hole 12, be respectively equipped with handgrip 11 and 8 on two clamps, two handgrips are 180 ° of angles, the utility model also has two screw

tap fixture blocks

14,15, it is shaped as the cylinder that cuts perpendicular to the bottom surface, its radius is slightly less than the radius of two smaller part circular grooves of frock groove 10, has 90 ° v-depression 13 on its rectangular side cross section vertical center line.

Its operation principle is: when need using screw die, see Fig. 3, be placed on screw die in the frock groove 10 and be adjacent to groove floor, tighten fastening jackscrew then, the screw die of different size is installed, can turn the adjustment screw according to its size.When needing to use screw tap, reamer, see Fig. 4: screw

tap fixture block

14,15 is put into frock groove 10, the four-prism at two screw taps, reamer rear portion partly is stuck in the square hole that the 90 ° of V-type grooves again on the screw

tap fixture block

14,15 form, and tightens fastening jackscrew then and can use.

The utility model only needs a shelf that screw die, screw tap, the reamer of variety classes, different size can be installed, obtain more than one with, saving material, easy to carry, use simple effect.

The invention will be further described below in conjunction with embodiment:

Present embodiment sees Fig. 1, two small semicircle groove radiuses that present embodiment constitutes the frock groove 10 of sub-elliptical are 22mm, on the curved surface sidewall of the groove center of fastening block 1, a fastening jackscrew 9 is housed, three fastening jackscrews 3 are housed on the groove curved surface sidewall on the opposite

side fastening block

6,4,5, fastening jackscrew 9 be positioned at jackscrew 3, fastening jackscrew 4 in the middle of 5 point-blank, the bent side of groove hit exactly to the wall thickness of fastening block another side be 7mm, bottom portion of groove wall thickness 5mm, the diameter of center hole 12 is 12mm, the screw tap fixture block 14 of present embodiment and 15 radius are 20mm, have top wire hole 18 on its lateral wall, one of two screw tap fixture block are big, one littler, is convenient to when the screw tap reamer is installed like this adjust.During with the screw die hitch,, can directly screw die be put into oval frock groove 10, tighten fastening jackscrew and can use (fastening jackscrew can be aimed at top wire hole or the jackscrew groove on the screw die lateral wall) if need the button of cover 3-10mm.The button that needs cover 10-16mm then unclamps and adjusts screw 2 and 7, screw die can be put into to hold out against.

Embodiment two sees Fig. 5, present embodiment is processed with the plurality of tooth-shaped protrusion on frock groove 10 curved surface sidewalls of sub-elliptical, like this when major diameter screw die (as 10-16mm) is installed, screw die can be put into the frock groove, fastening jackscrew 9 is aimed at the top wire hole or the jackscrew groove in the screw die outside, have the clamp clamping of toothed projections thing again with the two sides, can make screw die not take place to slide and rotate.
