Referring to Fig. 3, the utility model is made up of U-shape shackle 20, lock body 30, bayonet pin 40 and iron ring 50, wherein:

A U-shaped lock hook 20: its pipe body 21 is rectangular, and several circular grooves 23 with hypotenuses 22 are provided on the two opposite inner edges;

A lock body 30: the top and the front are respectively provided with a through placement hole 31 and a lock hole 32 matching the shape of the U-shaped lock hook 20, and an embedding groove 33 is set on the side to insert two relative cards. Pin 40, and the front edge of the lock body 30 is a semi-arc shape 34, and a front edge is built into the lock body for the control lock body 36 of the stop pin 35;

A bayonet pin 40: a cylinder 41 protruding outwards at one end and the end is chamfered, the other end is a pressing plate 43 provided with a notch 42, and a fitting hole 44 is set in front of the pressing plate 43 to embed a Compression spring 45;

An iron ring 50: for matching the semi-arc shape 51 of the front edge of the lock body 30, a hollow hole 52 is provided at the relative position of the lock hole 32 of the lock body 30, and a rubber pad 53 is placed on the inner edge of the iron ring 50;

Referring to Fig. 4, during combination, the bayonet pin 40 pressed against each other by the two pressure plates 43 and the spring 45 is placed in the embedding groove 33 of the lock body 30, and the notch 42 of the pressure plate 43 and the stop pin 35 of the control lock body 36 are used Engaging, so that the cylinder 41 of the detent 40 is just placed at the intersection of the placement hole 31 and the lock hole 32, please refer to Figure 5, when the U-shaped lock hook 20 is inserted into the lock hole 32 in parallel, the U-shaped lock hook can be used The circular groove 23 of 20 is engaged with the cylinder 41 of the bayonet pin 40. Because the upper side of the circular groove 23 is a hypotenuse 22, the U-shaped lock hook 20 can be pushed forward by the hypotenuse 22 to engage in different positions. When the circular groove 23 is combined with the cylinder 41, because the area outside the cylinder 41 is all topped in the area of the inner edge of the circular groove 23, the combined contact area of the two is relatively large, making the U-shaped lock When the hook 20 is pulled by an external force, the circular groove 23 and the cylinder 41 are still firmly combined and will not be disengaged from the clamping system. A key must be used to turn the stop pin 35 of the control lock body 36 to push the two detent pins 40 inwards to break away from the U-shaped hook 20. Locking hook 20 round groove 23 is clamped, and when retaining pin 35 is not rotated, spring 45 provided at the front end of pressing plate 43 promptly returns to the pressure position, and cylinder 41 is bounced back to the intersecting place of placement hole 31 and lock hole 32; Please refer to Fig. 6, similarly, when the U-shaped lock hook 20 is inserted through the placement hole 31, the cylinder 41 of the bayonet 40 can be used to engage the U-shaped lock hook 20 to increase the joint area, so that the U-shaped lock hook The lock hook 20 is not easy to be pulled by external force and breaks away from the clamping system. It is necessary to use the key to rotate the stop pin 35 of the lock body 36 to separate the cylinder 41 of the second bayonet pin 40 from the circular groove 23, so that the U-shaped lock hook 20 can be pulled out; please refer to the figure 7. When the utility model is installed on a motorcycle, the lock body 30 and the iron ring 50 must be combined with the screw A, so that the semi-arc shape 34 of the front edge of the lock body 30 and the semi-arc shape 51 of the iron ring 50 form a set of holes Clamp the motorcycle shock absorber 60 in it, and utilize the rubber pad 53 on the inner edge of the iron ring 50 to prevent the motorcycle lock from getting loose, so that the motorcycle lock is fixed on the shock absorber 60, and can be locked or opened as desired. Put the U-shaped lock hook 20 into the lock hole 32 or the placement hole 31 to achieve the purpose of easy use.

To sum up, since the pin block of the existing lock is a slope, the area that is restrained in the U-shaped lock hook slot is limited, and the slope of the block can accelerate the separation of the U-shaped lock hook slot from the block. The clamping system is not ideal in anti-theft effect; and the utility model utilizes the cylindrical body of the bayonet pin and the round groove of the U-shaped lock hook to be closely combined, and the area where the two push against each other is relatively large, even if the U-shaped lock hook is affected. Pulling or knocking by external force will not break away from the lock of the bayonet cylinder, and the anti-theft effect is better than that of the prior art. The same product has never been seen on the market, so the application is filed.
