The fixing structure 3 includes a fixing groove 31 opened on the side wall of the lock housing 1. A cavity 32 is provided inside the lock housing 1. An alarm body 33 is arranged on the side wall of the lock housing 1. A rotating rod 34 is rotatably connected to the side wall of the alarm body 33. A double-headed cam 35 is fixedly installed on the surface of the rotating rod 34. One end of a moving rod 36 passing through the inner wall of the fixing groove 31, the other end of the moving rod 36 passes through the side wall of the lock housing 1. A contact plate 310 is fixedly installed at one end of the moving rod 36 close to the double-headed cam 35. A return spring 311 is arranged on the surface of the moving rod 36. An arc groove 312 is opened on the side wall of the contact plate 310. A semi-arc-shaped clamping block 37 is fixedly installed on the inner wall of the arc groove 312. A protection structure 4 is arranged inside the lock housing 1. One end of the return spring 311 is fixedly connected to the inner wall of the notch fixing groove 31, and the other end of the return spring 311 is fixedly connected to the side wall of the contact plate 310. A handle 5 is fixedly installed at the end of the moving rod 36 located outside the lock housing 1. The double-headed cam 35 is adapted to both the arc groove 312 and the semi-arc-shaped clamping block 37.

[0022] Specifically, the fixing structure 3 of the technical solution of the utility model includes: a fixing groove 31, a cavity 32, an alarm body 33, a rotating rod 34, a double-headed cam 35, a moving rod 36, a semi-arc-shaped clamping block 37, a contact plate 310, a return spring 311, and an arc groove 312.

[0023] In an embodiment of the present utility model, a fixing structure 3 is provided to facilitate the fixing and use of the alarm device body 33 and the lock housing 1. When installing the alarm device body 33, the user can place the alarm device body 33 horizontally, and then insert the entire side of the horizontally placed alarm device body 33 into the fixing groove 31. Then, rotate the alarm device body 33. At this time, the rotating rod 34 drives the double-headed cam 35 to rotate. The rotation of the double-headed cam 35 will contact the contact plate 310 and move along the arc-shaped groove 312. Then, at this time, the double-headed cam 35 contacts one end of the semi-arc-shaped clamping block 37 and squeezes it, so that the double-headed cam 35 is limited by the other end of the semi-arc-shaped clamping block 37 with the inner wall of the arc-shaped groove 312, thus completing the installation and use. When disassembling, only need to move the moving rod 36 upward to drive the contact plate 310 to move upward to release the limit of the rotating rod 34, thus facilitating the use of the device.

[0024] Please continue to refer to Figures 1-4 , the protection structure 4 includes a limiting block 41 slidably connected to the inner wall of the cavity 32. A through hole 42 is provided on the side wall of the cavity 32. A sleeve 43 is fixedly installed on the surface of the moving rod 36. One end of a connecting rod 44 is hinged to the side wall of the sleeve 43, and the other end of the connecting rod 44 is hinged to the side wall of the limiting block 41. The through hole 42 and the lock hole are in a communicating state. By providing the protection structure 4, it is convenient to perform anti-theft limitation on the double-headed cam 35, thereby preventing the device from being stolen when used outdoors. When the lock housing 1 and the lock rod 2 are in a connected state, when the moving rod 36 is moved upward at this time, the moving rod 36 moves and drives the sleeve 43 on its surface to move. The movement of the sleeve 43 drives the connecting rod 44 on its side wall to move. The movement of the connecting rod 44 drives the limiting block 41 hinged to it to move and enter the through hole 42. However, since the lock rod 2 is located inside the lock hole at this time, the limiting block 41 cannot continue to move, which also makes the moving rod 36 unable to move too much to release the limit of the rotating rod 34, thereby improving the practicality of the device. When the lock housing 1 and the lock rod 2 are not in a connected state, the limiting block 41 can directly move and enter the through hole 42 to release the limit of the rotating rod 34, thus facilitating the user to disassemble and use, and being anti-theft.

[0025] During operation, when installing, the entire side of the horizontally placed alarm body 33 is inserted into the inside of the fixing groove 31, and then the alarm body 33 is rotated. At this time, the rotating rod 34 drives the double-headed cam 35 to rotate. The rotation of the double-headed cam 35 will contact the contact plate 310 and move along the arc-shaped groove 312. Then, at this time, the double-headed cam 35 contacts one end of the semi-arc-shaped clamping block 37 and squeezes it, so that the double-headed cam 35 is limited by the other end of the semi-arc-shaped clamping block 37 and the inner wall of the arc-shaped groove 312. When disassembling, the lock shell 1 and the lock rod 2 need to be opened, and then the moving rod 36 is toggled upward. At this time, the moving rod 36 moves and drives the sleeve 43 on its surface to move. The movement of the sleeve 43 drives the connecting rod 44 on its side wall to move. The movement of the connecting rod 44 drives the limiting block 41 hinged to it to move and enter the through hole 42, so as to release the limit of the rotating rod 34. Then, the user can reverse-rotate the alarm body 33 once to complete the disassembly, thereby improving the practicability of the device.

[0026] The above text has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
