Fixed head 4 is covered on the alcove 20 of pedestal 2, cooperate the long perforation 202 of pedestal 2 and 204 positions of boring a hole on the fixed head 4, the corresponding open- work 40,41 that is provided with, with magnet 21 positions of pedestal 2, corresponding being provided with bores a hole 42, and corresponding to chute 24 positions of pedestal 2, corresponding being provided with worn groove 43, and it is corresponding with the perforation 32 of baffle plate 3 that the side of fixed head 4 is provided with a kerf 44, and all green majority that is provided with of fixed head 4 bores a hole 45, stretch through for affixed element 46, fixed head 4 is set firmly with pedestal 2 combine;

Beam ring 5 is by on the rear wall of being located at pedestal 2, and the affixed element 203 by being located at long perforation 202 in the pedestal 2 is in affixed, and two ends of beam ring 5 are provided with location-plate 50, and location-plate 50 is provided with perforation 51;

Clamshell 6 covers at the outside of pedestal 2, and the position that clamshell 6 aligns locking bar 26 and push pedal 27 is provided with an open-work 60, and key hole 28 places that align lock 22 in the sidewall of clamshell 6 are provided with a key hole 61 relatively.

Cooperate and to consult Fig. 4-shown in Figure 7, during assembling, two affixed elements 203 are arranged in respectively in the long perforation 202 of pedestal 2, and be arranged in the perforation 51 of beam ring 5 and locked, in addition baffle plate 3 is located in the alcove 20 of pedestal 2, make its back side held by the follow blocks 200 in pedestal 2 alcoves 20, root edge is then by being held on the plate body 201 of location, baffle plate 3 is by being held in left and right sides slippage on the plate body 201 of location, and with the long perforation 202 of pedestal 2 and bore a hole and 204 covered and block resistance, shown in Fig. 7,8;

And 30 at the otch of baffle plate 3 is striden and is located at locking bar 26 tops, 31 blocks of block face are in the side wall surface of locking bar 26, make outwards pull slippage of baffle plate 3, be limited in the alcove 20 of pedestal 2, be fixedly arranged on fixed head 4 on the alcove 20 of pedestal 2 by affixed element 46 again, 27 grooves 43 of wearing by fixed head 4 of the push pedal that its locking bar 26 front ends are pivoted stretch through out, and the elastic force pressure holding by wind spring 270, push pedal 27 pushed be 90 degree and be provided with, and by on the wall that is held in fixed head 4, the magnet 21 of pedestal 2 then is convexly set in the perforation 42 of fixed head 4, and its push pedal 27 can be subjected to magnet 21 stickings, and firm absorption is positioned on the fixed head 4;

At last, again clamshell 6 is covered at pedestal 2 outsides, so, can finish whole assembling.

If the time spent, lucerne is a straight line with push pedal 27 outside switchings 90 degree and locking bar 26 earlier to desire, as shown in Figure 7 with the lockset group; With push pedal 27 to pedestal 2, chute 24 in pass, as shown in Figure 9, locking bar 26 is slippage backward in the lump, 260 of the convex bodys of locking bar 26 bottoms can compress the spring 261 of being located at the bottom and be elastic compression, the bayonet lock 250 of latch components 25 then inwardly shrinks along caulking groove 262 scarves of locking bar 26, end face slippage along locking bar 26, when treating the position of grooving 271 squaring pushers 3 of push pedal 27 end faces, utilize instrument to stretch through in the perforation 32 of baffle plate 3, the alcove 20 interior otch 29 by grooving 271 and pedestal 2 of baffle plate 3 from pedestal 2 are outwards pulled out, as shown in figure 10;

Baffle plate 3 is no longer covered and block resistance growing perforation 202 and boring a hole 204 in pedestal 2, so, the pedestal 2 of lockset can be located at a side of wheel, beam ring 5 then cover is restrainted on the front fork stalk 17 of vehicle, two ends of its beam ring 5 are then by on the rear wall of being located at pedestal 2, and affixed element 203 is extended through in the perforation 51 of location-plate 50, and be extended through the open-work 40 of fixed head 4 by instrument, 41, the affixed element of being located in pedestal 2 alcoves 20 203 is locked mutually with beam ring 5, the steady state of lockset can be mounted on the locomotive front fork stem 17, after the firm group of lockset is established, again baffle plate 3 is passed in alcove 20, baffle plate 3 is covered once more and block resistance in the long perforation 202 of affixed element 203 and each and bore a hole 204, and the grooving 271 of push pedal 27 no longer is subjected to baffle plate 3 spacing being inserted in the chute 24, then locking bar 26 can be subjected to spring 261 to be elastic recovery, in the lump with push pedal 27 outside pushing tows, move outside the push pedal 27 and be subjected to pushing of wind spring 270 to be 90 degree with locking bar 26 once more and be provided with, and be adsorbed on the magnet 21 of pedestal 2, the block face 31 of baffle plate 3 once more block in the side wall surface of locking bar 26, can't move outward, clamshell 6 on pedestal 2 outer cup again, so, lockset firmly can be mounted on the preceding bar again 17 of wheel, as shown in figure 11;

Insert when lock stalk 26 and to pull that the bayonet lock 250 by latch components 25 is arranged in the grooving 271 of push pedal 27 between spoke, be when locking state, baffle plate 3 is subjected to 27 stopping of sidewall of push pedal and outside pull, as shown in figure 12, can reach the purpose of snap close really; When desire is removed snap close, must insert in the key hole and can trip with key 7, and by baffle plate 3 with the long perforation 202 of affixed element 203 and pedestal 2 and bore a hole and 204 cover and stop, can prevent more after locking that the burglar from being stretched in people's pedestal 2 by the open- work 40,41 of fixed head 4 by instrument, affixed element 203 is unscrewed, to put in order the group lockset and pull down, have splendid antitheft effect from wheel.

In sum, the utility model has been linked desired application target and effect really, and more traditional lock is even more ideal and practical, has the value on the industry, and before application, do not see in the ware, so the application has novelty, practicality and creativeness.
