The specific embodiment
As shown in Figure 2, retaining mechanism of the present utility model is made of retainer plate 6, moving-coil 7 and steel ball 8.Two lug bosses 9 that radially form are relatively arranged on the retainer plate 6, two handles 10 that radially form are relatively arranged on the moving-coil 7.As shown in Figure 5, be formed with corresponding retainer plate locating slot 19 and moving-coil handle hole 20 on the main frame body.During assembling, shown in Fig. 6 and 7, the lug boss 9 on the retainer plate 6 is contained in the corresponding retainer plate locating slot 19 and can not rotates, and the handle 10 on the moving-coil 7 is contained in the corresponding moving-coil handle hole 20.The size of moving-coil handle hole 20 can make the motion along the circumferential direction therein of moving-coil handle.
Shown in Fig. 2,3 and 4, be formed with a collar flange 11 on the inner ring of retainer plate 6, be formed with a plurality of grooves 12 on the collar flange 11, be preferably six grooves, have little seam 13 in the inboard of groove 12, seam 13 is used to block steel ball 8, prevents that steel ball free from coming off.Shown in Fig. 2,11 and 12, moving-coil 7 with face that retainer plate 6 matches on be formed with an annular recess 14 towards the outward flange direction of moving-coil 7.When retainer plate and moving-coil fitted together, the recess 14 on the moving-coil 7 can relevantly cooperate with the collar flange 11 on the retainer plate 6, and moving-coil 7 can be rotated with respect to retainer plate 6, and the circular open in the middle of their can be used for laying the working head neck.The periphery of the recess 14 of moving-coil 7 is formed with a plurality of ears hole portion 15, and the number of the groove 12 on the number of ear hole portion 15 and the retainer plate 6 is identical, is preferably also six.Ear hole portion 15 comprises larger-size part 16 and the less part 17 of size, interconnects by inclined-plane 18, an ear hole between the part 16 and 17.
Fig. 8,9 and 10 shows the structure of working head neck.The neck 22 of working head 21 is designed to cylindrical according to retaining mechanism, the first step circumference that the working head neck matches with moving-coil and retainer plate is provided with two semicircle locking slots 23, the length of working head neck and the position of locking slot are arranged to, when working head installed on the main frame body, steel ball can be arranged in locking slot 23.The second step of working head neck is provided with positioning key 24 and the assist location key 25 that cooperates with the main frame body.Positioning key 24 and assist location key 25 can not rotate working head in casing, also can not make working head direction dress anti-.
After moving-coil and retainer plate are assembled on the main frame body, retainer plate is positioned at locking or does not rotate when unclamping working head by host machine casing, by stirring the moving-coil handle moving-coil can be rotated a certain angle with respect to retainer plate, this angle is limited by the handle hole on the casing, is preferably 6 °.
Below describe retaining mechanism of the present utility model and be and how to lock and unclamp working head.For the ease of watching, Figure 11 and 12 shows the work schematic diagram of the retaining mechanism that direction looks shown in the arrow A in Fig. 5.
After working head inserts retaining mechanism, as shown in figure 11, rotate predetermined angle with the moving moving-coil handle 10 of hand-lifting along direction shown in the arrow B, be preferably 6 °, because steel ball 8 and retainer plate 6 are fixed, moving-coil 7 rotates with respect to steel ball 8 along the inclined-plane 18, ear hole of Qi Erkeng portion, makes steel ball 8 arrive the smaller portions 17 that are in ear hole portion from the major part 16 that is in ear hole portion.In this process, steel ball 8 is pressed onto in the locating slot on the retainer plate 6 by moving-coil 7, and the part of steel ball is in the locking slot 23 on the working head neck.After steel ball arrived position shown in Figure 11, steel ball 8 was by the smaller portions 17 hoop jails of moving-coil ear hole portion, and steel ball 8 tightly is stuck in the working head neck locking slot 23 can not move freely, thereby working head can be locked on the combination tool main frame body.
When needs take off working head, as shown in figure 12, move moving-coil handle 10 along rotating predetermined angle with hand-lifting with square C in the opposite direction shown in the arrow B, moving-coil 7 rotates with respect to steel ball 8 along the inclined-plane 18, ear hole of Qi Erkeng portion, make steel ball 8 arrive the ear hole portion major part 16 that is in releasing orientation from the ear hole portion smaller portions 17 that are in locking state, that is, make the ear hole portion major part 16 of moving-coil and the position alignment of steel ball 8.At this moment, firmly be pulled outwardly moving working head, steel ball 8 rolls to ear hole portion major part 16 under the effect of the power that is pulled outwardly moving working head, like this, just has been totally released working head, can easily working head be taken off from combination tool main frame body.
As shown in figure 13, the working head that can be installed on the main frame body 26 of the combination tool that comprises the utility model retaining mechanism comprises reciprocating-type saw working head 27, sanding machine working head 28, electric drill working head 29, sander working head 30, engraving machine working head 31 and other suitable working head.
The utility model also relates to a kind of combination tool that comprises above-mentioned retaining mechanism.
