Additionally, the working method and principle of the of the invention each part according to described in embodiment herein above, it is known that it should possess some optional implementation methods respectively, as follows be explained citing.
Alternatively, although the lateral profile of hollow shaft housing and inner side profile are defined to positive dodecagon profile and regular hexagon profile respectively in above example.But understand that the purpose being so designed that is to enable that hollow shaft housing firmly couples with first section for coupling section and heart axle of hub internal bore respectively, and then torque can be stably transferred to sleeve from heart axle when complete equipment works, and and then be transferred to hole saw.Further, the lateral profile of hollow shaft housing is defined to positive dodecagon profile, more mainly be for having completed pre-installation in heart axle and hole saw in the state of, if alignment pin cannot be aligned with hole saw, for the reverse rotation of heart axle, to provide more regulation angles for selection, therefore the reverse angle of heart axle is reduced as few as possible, and then reduces heart axle unscrew degree relative to hole saw.Based on principles above, it can also be designed to make the connection section of endoporus that there is the first regular polygon profile for matching with the lateral profile of hollow shaft housing；And/or the first section of heart axle has the second regular polygon profile for matching with the inner side profile of hollow shaft housing.Because regular polygon profile can provide relatively firm connection and various adjustable reverse angles during the above-mentioned part of engagement is engaged two-by-two, therefore it equally can be suitably used for herein.The structure designs such as specific angle number, the number of degrees as regular polygon profile, then should combine the many-side such as design space, size, practical application performance of part and consider in the lump.
Alternatively, the first regular polygon profile and the second regular polygon profile can also be made has the summit staggered in the circumferential, it is so designed that, so that in the case of the angle number and the number of degrees of the first regular polygon profile and the second regular polygon profile are fixed, can also be by for selection to provide relatively more and relatively smaller maximum reverse angles to shifting to install between profile angular vertex, this will further avoid between heart axle and hole saw excessively lax connection.
Alternatively, the first section of heart axle is set into regular hexagon profile allows it while matching the regular hexagon profile in the output shaft hole of the drive division of hollow shaft housing and offer power, the simplicity that further raising is processed and assembled.
Alternatively, the base portion 430 in positioning component 400 mentioned above can use bolt, and it has relatively suitable locating effect and cost viewpoint.
Alternatively, retaining component 500 mentioned above can use retaining spring, and it simultaneously has relatively suitable locating effect and cost viewpoint.
The quick assembling process of adapter of the invention and hole saw is described below in conjunction with Figure 10 to Figure 13.
First, moving sleeve 100 axially upward, until positioning bead slides into the release connection slot on heart axle 200, now the release section 112 of endoporus 110 is matched with the first section 210 of heart axle 200, thus heart axle 200 can be rotated independently of sleeve 100.Hereafter, the rotation of heart axle 200 can be screwed into the axis hole 810 at the center of hole saw 800, preliminarily forms the connection of heart axle and hole saw.Then, turnbarrel 100 makes the alignment pin 600 that it is installed on its ring flange 120 be aligned with the pin mounting hole 820 in hole saw 800.Now, if cannot being narrowly focused towards with heart axle 200 if there is sleeve 100, slightly reversion will be taken to unscrew heart axle 200 to realize the alignment of the two.Finally, sleeve is depressed into downwards in alignment pin 600 is inserted hole saw 800, now first section 210 of heart axle 200 departs from the release section 112 of endoporus 110, and is matched with the section 111 that couples of endoporus 110, thus heart axle 200 is in the coupled position that can be in the lump rotated with moving sleeve 100.So far the installation of hole saw 800 and adapter has been completed, the normal work of hole saw 800 has been driven by then adapter is plugged on drive division.Alternatively, hole saw and adapter are if desired dismantled, more than reverse execution is operated.
