-drive unit 250 comprises knob 251 and the cam 252 that is connected with knob 251, cam 252 and joint 243 mutually against, also be provided with on the cam 252 for spacing and bump pearl 253.
Based on above-mentioned setting, can realize locking or the release movement of locking device by rotation manipulation knob 251.
Below will cooperate Fig. 6 and Fig. 7 to describe the working principle of this locking device in detail.Left-half among Fig. 6 and Fig. 7 is locking state, and right half part is releasing state, and wherein, releasing state are the normality of locking device.
Specifically, Fig. 6 is depicted as the work relationship figure between cam 252 and the slide block 240 from the left side of locking device.By rotation knob 251, can drive cam 252 and in the state shown in the left and right sides of Fig. 6, switch.Shown in left-half among the figure, when the joint 243 of the protuberance 2521 of cam 252 and slide block 240 mutually against the time, slide block 240 is in the bottom of sliding area; Shown in right half part, when the joint 243 of the round portion 2522 of cam 252 and slide block 240 mutually against the time, slide block 240 is in the top of sliding area.
Fig. 7 further shows the work relationship figure between cam 252, slide block 240 and the lock sheet 231,232 from the right side of locking device on the basis of Fig. 6.Chute 242 shown in Fig. 7 is half groove, non-groove.
Earlier referring to right half part, when the joint 243 of the round portion 2522 of cam 252 and slide block 240 mutually against the time, slide block 240 is in the top of sliding area, lock sheet 231,232 bent axle 2314,2324 lay respectively at the bottom 2421 of chute 242, at this moment, the clamping part 2313 of first lock sheet and second lock sheet, 2323 are in vertical position, release portion 2315,2325 are horizontal and towards center fork 290, two release portions 2315,2325 have complemented each other to form a release areas greater than center fork 290 cross-section areas, permission center fork 290 is free movable in this release areas, this release areas can equal the sphere of activities that the center hole 211 greater than base 210 limits, and also can be slightly less than this sphere of activities.
When user's operation knob, with the joint 243 of the protuberance 2521 of cam 252 and slide block 240 mutually against.At this moment, slide block 240 is in sliding area, and from up to down along vertical slot 241 slip LAP h and slide into the bottom of sliding area, lock sheet 231,232 bent axle 2314,2324 move to chute 242 tops 2422 respectively.Because bent axle is not coaxial with the end axle of lock sheet, therefore, the mobile lock sheet 231,232 that drives of bent axle is around the first coaxial end axle 2311, the 2321 and second end axle 2312,2322 rotations, thereby make the clamping part 2313,2323 of lock sheet be horizontal, and towards center fork 290, release portion 2315,2325 then is in vertical position.Clamping part 2313,2323 has complemented each other to form a size and the close-fitting shape of center fork 290 cross-section areas, thereby has clamped center fork 290.
When user's operation knob again, the protuberance 2521 of cam 252 is left joint 243, the elastic force that slide block 240 will be discharged by spring section 244 medi-springs is the top upwards, to return to releasing state.
In order to promote the clamping effect, can adopt following dual mode:
(1) also extends one section limit position 2423 straight up at the top 2422 of chute 242, make chute 242 form " L " shape chute of a pair of accumbency shape, when bent axle 2314,2324 slided to this limit position 2423, clamping part 2313,2323 can fully be locked center fork 290;
(2) increase several juts 2316,2326 at clamping part 2313,2323, thereby increase the area of contact of clamping part and center fork.
In addition, as shown in Figure 8, in order to allow the power switch 260 of locking device and laser device link, can in two lock sheeies, a linkage portion 233 be set the second end axle of any one, this linkage portion 233 links to each other with the power switch 260 of laser device or leans, when lock sheet was in locking state, power switch 260 was closed condition; When lock sheet is in releasing state, 260 one-tenth opening states of power switch.
Should be noted that, embodiment of the present utility model has preferable implementation, and be not that the utility model is done any type of restriction, any person skilled in art of being familiar with may utilize the technology contents change of above-mentioned announcement or be modified to the effective embodiment who is equal to, in every case the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any modification or equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
