In other words, the link belt second end portion 302 is rotatably connected to the inside of the end of the long side of the L-shaped body 100.

In different angles, the body 100 is recessed inward at a position near one side to form the limiting portion 110, the other side extends outward toward the opening of the limiting portion 110 to form a support arm 101, and the second end 302 of the chain belt is coupled to one end of the support arm 101 away from the limiting portion 110 and toward the limiting portion 110.

In the embodiment shown in fig. 1B, when the second end portion 302 of the fastener tape is inserted into the position-limiting portion 110, the position-limiting element 120 can move to at least partially enter or exit the body 100, so as to limit or open the second end portion 302 of the fastener tape to leave the position-limiting portion 110. Further, as shown in the cross-sectional view of the embodiment shown in fig. 2, the fixing device 900 further includes a lock body 500 disposed in the body 100, and when the lock body 500 is in a locked state, the lock body 500 limits the movement of the limiting member 120 out of the body 100.

Specifically, as shown in the embodiment of fig. 2, an engaging portion 121 is disposed on a side of the position-limiting member 120, and when the lock 500 is in a locked state, the lock 500 engages with the engaging portion 121 to limit the position-limiting member 120 from moving out of the body 100. More specifically, the lock body 500 includes a catch 510 and a driver 520. The driving member 520 abuts against the engaging member 510. The stopper 120 is movable in a direction parallel to the X-axis. The engaging member 510 is movable in a direction parallel to the Y axis, and the engaging portion 121 is a recess provided on a side surface of the engaging member 120. The driving member 520 includes a driving protrusion 521, the driving protrusion 521 extends into the engaging member recess 511 along a direction parallel to the X-axis, and the driving member 520 can rotate along a direction parallel to the Y-Z plane to move the engaging member 510 to engage with or disengage from the engaging portion 121. The X, Y, and Z axes are orthogonal.

As shown in fig. 3A and 3B, when the lock body 500 is in the locked state, one end of the engaging element 510 extends into the engaging portion 121 to engage therewith, so as to limit the movement of the limiting member 120 along the direction parallel to the X axis to exit from the main body 100 (see fig. 3B), and at this time, the limiting member 120 passes through the second end portion 302 of the chain belt, so as to limit the second end portion 302 of the chain belt to leave the limiting portion 110. The lock body 500 further includes an engaging member elastic member 210 for providing an elastic force to move the engaging member 510 toward the position-limiting member 120.

In the embodiment shown in fig. 4A and 4B, when the user turns the key 590 to unlock the lock body 500, the driving member 520 rotates in a direction parallel to the Y-Z plane, and drives the driving protrusion 521 in the engaging member recess 511 to rotate in a direction parallel to the Y-Z plane, so as to drive the engaging member 510 to move away from the engaging portion 121 in a direction parallel to the Y axis, thereby releasing the restriction of the limiting member 120 moving in a direction parallel to the X axis to exit the body 100.

As shown in fig. 5A and 5B, when the restriction of the movement of the limiting element 120 along the direction parallel to the X axis is released, the limiting element 120 can be withdrawn from the body 100. For convenience of use, the fixing device 900 further includes a limiting member elastic member 220 for providing an elastic force for the limiting member 120 to exit from the body 100. When the stopper 120 is withdrawn from the body 100, the second end portion 302 of the chain belt can leave the stopper 110 as shown in fig. 6, the chain rods 310 connected in series can be moved and dislocated to unfold the chain belt 300, so that the second end portion 302 of the chain belt can pass through an object to be fixed, such as a bicycle wheel frame, and then the stopper 110 is inserted as shown in fig. 7, and the lock body 500 is restored to the locked state to restrict the second end portion 302 of the chain belt from leaving the stopper 110, thereby achieving the purpose of locking.

On the other hand, as shown in the embodiment of fig. 5A and 5B, the fixing device 900 further includes an anti-disengagement device 400 disposed in the body 100, when the limiting element 120 moves to disengage from the body 100, the anti-disengagement device 400 can move along a direction parallel to the Y axis to engage with the engaging portion 121, so as to prevent the limiting element 120 from completely disengaging from the body 100.

In the above embodiments, the lock body 500 uses a key cylinder, however, in different embodiments, the lock body 500 may use other cylinders. On the other hand, in the above embodiment, the stopper 120 is retracted from the body 100 on the opposite side of the body 100 to the side where the key 590 is inserted. However, in various embodiments, the position-limiting member 120 may exit the body 100 at other positions depending on manufacturing, use or design considerations.

In a different embodiment, as shown in fig. 8A and 8B, the limiting member 120a can be withdrawn from the body 100a on the same side of the body 100a as the key 590a is inserted. Further, as shown in fig. 9A and 9B, in the embodiment, an engaging portion 121a is disposed on a side of the limiting member 120a, and when the lock body 500a is in a locked state, the lock body 500a is engaged with the engaging portion 121a to limit the limiting member 120a from moving out of the main body 100 a.

Specifically, as shown in the embodiment of fig. 9A to 9C, the lock body 500a includes a clipping member 530, a control member 540 and a lock body 550 that are sleeved with each other. The control member 540 abuts the engaging member 530. The stopper 120a is movable in a direction parallel to the X-axis. The engaging portion 121a is a through hole disposed on a side surface of the stopper 120 a. The control member 540 extends into the position-limiting member 120a along a direction parallel to the X-axis, and has a control member recess 541 on a side surface thereof. The engaging member 530 is movable in the engaging portion 121a and abuts against a side surface of the control member 540. The control 540 may be rotated in a direction parallel to the Y-Z plane. The X, Y, and Z axes are orthogonal.

More specifically, as shown in fig. 9C, the position-limiting element 120a includes a position-limiting element body 122 and a rod 124 that are sleeved with each other, and the rod 124 and the lock body 550 can be sleeved with each other and fixed by a pin 123. When the second end 302a of the link belt is located in the position-limiting portion 110a, the rod 124 can pass through the second end 302a of the link belt. The control member 540 is cylindrical and is sleeved outside the lock body 550 and the rod member 124, the side wall of the control member 540 is further provided with a guide groove 542 arranged along the circumferential direction, and the pin member 125 is inserted into the guide groove 542 so as to limit the rotation of the control member 540 relative to the limiting member 120 a.

In the embodiment shown in fig. 9A and 9B, when the lock body 500a is in the locked state, the control member recess 541 is misaligned with the engaging portion 121a, and the movement of the engaging member 530 relative to the engaging portion 121a is limited, so as to limit the movement of the limiting member 120a to exit the main body 100 a. Furthermore, the inner side of the body 100a may further have a limiting recess 109, when the lock body 500a is in the locked state, the control member recess 541 and the engaging portion 121a are dislocated, and a part of the engaging member 530 extends into the limiting recess 109 from the engaging portion 121a to limit the movement of the limiting member 120a out of the body 100 a.

As shown in fig. 10A and 10B, when the user turns the key 590A to unlock the lock 500A, the lock body 550 rotates along a direction parallel to the Y-Z plane, so as to rotate the locking member 540 until the locking member recess 541 is opposite to the engaging portion 121 a. Thereby, the engaging member 530 can move relative to the engaging portion 121a, and the restriction of the movement of the limiting member 120a out of the main body 100a is released. More specifically, as shown in the embodiment of fig. 11A and 11B, since the engaging member 530 is movable relative to the engaging portion 121A away from the limiting recess 109, the limiting member 120a can be moved to exit the main body 100 a.

When the stopper 120a is withdrawn from the body 100a, the second end 302a of the chain belt can be separated from the stopper 110a as shown in fig. 12, the chain rod 310a connected in series can be moved and dislocated to unfold the chain belt 300a, so that the second end 302a of the chain belt can pass through an object to be fixed, such as a bicycle rim, and then the stopper 110a is inserted into the lock body 500a (see fig. 11A) to return to a locked state as shown in fig. 13, so as to restrict the second end 302a of the chain belt from separating from the stopper 110a, thereby achieving the purpose of locking.
