The working principle and process for using of the utility model: after the utility model installs, before passing through drill bit 1 first most
It holds 9 inside of fixation hole on outer wall high-intensitive particle 10, then mounting rod 4 is inserted by the plug 7 on mounting rod 4 outer
In portion's fixed equipment, and it is last the combination drill and external equipment progress to pass through the fixed ring 5 on mounting rod 4 and fixing groove 6
It reinforces and fixes, then when in use, external equipment drives entire combination drill to carry out high speed rotation, drills first with needs at this time
Material is high-intensitive particle 10, the material that the high-intensitive meeting of particle 10 accelerated wear test needs to drill, then drill bit 1 and drilling rod
2 carry out drilling operation by drill flute 3, and increase an opening to the right the mounting rod of the combination drill 4 is transversely inner
Bracing means 11, and the bracing means 11 is arranged in the transversely inner adult font changed from small to big from left to right of mounting rod 4, and should
Cross sectional shape of the bracing means 11 inside mounting rod 4 is regular hexagon, enables to the combination drill stronger in this way
Be mounted on external equipment, in this way when carrying out installing fixed to the combination drill by mounting rod 4, it is only necessary to external connection
Increase the installation fixed link that a shape and length can be completely bonded with bracing means 11 in equipment, because bracing means 11 exists
The transversely inner adult font arrangement changed from small to big from left to right of mounting rod 4, enables to the combination drill passing through reinforcing in this way
Device 11 carries out installation and removal and gets up all very convenient, and because the level-one fixing collar 12 of bracing means 11, second level are reinforced
Circle 13, three-level fixing collar 14, level Four fixing collar 15 and end fixing collar 16 are in regular hexagon, and level-one fixing collar 12, second level add
Admittedly angle is handed between any two inside mounting rod 4 between circle 13, three-level fixing collar 14, level Four fixing collar 15 and end fixing collar 16
Mistake carries out mounting arrangement, and installation fixed link increased on external equipment is only needed to be directly inserted into inside bracing means 11 in this way
Afterwards, the installation fixed link of external equipment firmly stuck can be locked in the fixing collar of hexagon, to increase entire combination
The installation fastness of brill, so that combination drill is able to bear bigger impact force and centrifugal force without generating loosening.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
