[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] The following will describe in detail the specific settings and functions of the disassembly and assembly mechanism and the storage mechanism.

[0024] Reference Figure 1-Figure 3As shown, in this embodiment: the user places the sensing probe 5 close to the device on which the coupler is installed. During the rotation of the coupler, the vibration frequency of the device is transmitted to the detector 2 through the sensing probe 5 to determine the operation status of the coupler. When the detector 2 needs to be repaired, the L-shaped limit plate 10 is pulled forward to disengage from the inside of the limit slot 9, and the limit on the detector 2 is released, so that the detector 2 can be taken out from the inside of the outer box 1 for easy maintenance. The rear end of the first placement slot 8 is fixedly connected with a reset spring 11, and the front end of the reset spring 11 is fixedly connected to the rear end of the L-shaped limit plate 10. When the user needs to disassemble the detector 2 for maintenance, the user pulls the L-shaped limit plate 10 out of the inside of the limit slot 9 to release the limit on the detector 2 so that the detector 2 can be taken out upward for easy maintenance of the detector 2. After the maintenance is completed, pull the L-shaped limit plate 10 The L-shaped limit plate 10 moves to the front end, and the reset spring 11 accumulates force. After the detector 2 is placed inside the outer box 1, the L-shaped limit plate 10 is released. Under the action of the reset spring 11, the L-shaped limit plate 10 is driven to insert into the limit groove 9 to fix the detector 2. The bottom end of the outer box 1 is fixedly connected with a buffer spring 12, and the top of the buffer spring 12 is fixedly connected with a top plate 13. The top of the top plate 13 is fitted and connected with the bottom of the detector 2. After the user pulls the L-shaped limit plate 10 to release the limit on the detector 2, the buffer spring 12 at the bottom of the detector 2 pushes the detector 2 upward to move a distance. After the maintenance is completed, the slider 7 is aligned with the position of the slide groove 6 and installed into the detector 2. During the descent of the detector 2, the buffer spring 12 buffers the movement of the detector 2 to prevent the bottom of the detector 2 from colliding with the bottom of the outer box 1.

[0025] Reference Figure 1 , Figure 4 and Figure 5As shown, specifically, two storage grooves 14 are evenly arranged at the bottom of the outer box 1, and both sides of the storage grooves 14 are fixedly connected with a rotating shaft 15, and the surface of the rotating shaft 15 is rotatably connected with a support leg 16. When the user detects the operation of the coupler, the support leg 16 is rotated to support the outer box 1, so that the outer box 1 can be placed on the ground, so that the user does not need to hold the outer box 1 in his hand for operation, saving physical strength. When the detector 2 needs to be taken for maintenance, the support leg 16 is rotated to enter the interior of the storage groove 14 to store the support leg 16 for easy carrying. Two second placement grooves 17 are evenly arranged at the bottom of the outer box 1, and an L-shaped plug plate 18 is slidably connected to the interior of the second placement groove 17. The top of the L-shaped plug plate 18 is fitted and connected to the top of the support leg 16. When the user needs to carry the outer box 1, the support leg 16 is rotated back to the interior of the storage groove 14 and placed in the second placement groove. The L-shaped plug plate 18 is moved toward both ends inside the slot 17 so that the L-shaped plug plate 18 limits the leg 16 to prevent the leg 16 from being supported apart during carrying. The rear end of the L-shaped plug plate 18 is fixedly connected to a thrust spring 19, and the rear end of the thrust spring 19 is fixedly connected to the rear end inside the second placement slot 17. When the user needs to spread the leg 16, the L-shaped plug plate 18 is first moved toward the middle to release the limit on the leg 16, and the leg 16 is rotated to support the outer box 1. When the leg 16 needs to be stored, the L-shaped plug plate 18 is moved toward the middle, and the thrust spring 19 accumulates force. After the leg 16 is rotated to the inside of the storage slot 14, the L-shaped plug plate 18 is released, and the thrust spring 19 pushes the L-shaped plug plate 18 to move toward both ends under the action of the thrust spring 19 to limit the leg 16, so as to prevent the L-shaped plug plate 18 from being displaced by gravity during carrying, and the leg 16 cannot be limited.

[0026] The practical working principle of the present invention is that the user places the sensing probe 5 close to the device installed with the coupler. During the rotation of the coupler, the device vibration frequency is transmitted to the detector 2 through the sensing probe 5 to determine the operation status of the coupler. When the detector 2 needs to be repaired, the L-shaped limit plate 10 is pulled forward to disengage from the inside of the limit groove 9, and the limit on the detector 2 is released, so that the detector 2 can be taken out from the inside of the outer box 1. When the detector 2 needs to be disassembled for maintenance, the L-shaped limit plate 10 is pulled out of the inside of the limit groove 9 to release the limit on the detector 2 so that the detector 2 can be taken out upward, which is convenient for the detection. The detector 2 is repaired and after the repair is completed, the L-shaped limit plate 10 is pulled to move to the front end, and the reset spring 11 is charged. After the detector 2 is placed in the outer box 1, the L-shaped limit plate 10 is released. Under the action of the reset spring 11, the L-shaped limit plate 10 is driven to insert into the limit groove 9 to fix the detector 2. After the L-shaped limit plate 10 is pulled to release the limit of the detector 2, the buffer spring 12 at the bottom of the detector 2 pushes the detector 2 upward to move a distance. After the repair is completed, the slider 7 is aligned with the position of the slide groove 6 and installed into the detector 2. During the descent of the detector 2, the buffer spring 12 The support legs 16 are used to buffer the bottom of the detector 2 and prevent the bottom of the outer box 1 from colliding. When the user detects the operation of the coupler, the support legs 16 are rotated to support the outer box 1, so that the outer box 1 can be placed on the ground, so that the user does not need to hold the outer box 1 in his hand for operation, saving physical strength. When the detector 2 needs to be taken for maintenance, the support legs 16 are rotated to enter the interior of the storage slot 14 to store the support legs 16. When the outer box 1 needs to be carried, the support legs 16 are rotated back to the interior of the storage slot 14, and the L-shaped plug plates 18 are moved to both ends in the second placement slot 17 so that the L-shaped plug plates 18 are aligned with the support legs 16. The legs 16 are limited in position to prevent them from being spread apart during carrying. When the legs 16 need to be spread apart, the L-shaped plug plates 18 are first moved toward the middle to release the limit on the legs 16, and the legs 16 are rotated to support the outer box 1. When the legs 16 need to be stored, the L-shaped plug plates 18 are moved toward the middle, and at the same time, the thrust springs 19 are charged. After the legs 16 are rotated to the inside of the storage slots 14, the L-shaped plug plates 18 are released, and under the action of the thrust springs 19, the L-shaped plug plates 18 are pushed to move toward both ends to limit the legs 16, preventing the L-shaped plug plates 18 from being displaced by gravity during carrying, and making it impossible to limit the legs 16.
