[0036] refer to Figure 3-6 As shown, the fastening assembly 2 includes a connecting plate 201 with a long rectangular structure. Symmetrically arranged on both sides of the connecting plate 201 are baffles 202 integrally formed therewith. A travel groove is formed within the baffle 202, and a travel block 218 is provided within the travel groove. A driving groove 216 communicating with the travel groove is formed on the top surface of the baffle 202. First insertion grooves 215 are formed on both sides of the baffle 202 of the driving groove 216. A bottom plate is slidably disposed within the driving groove 216. The drive rod 213 is connected to the travel block 218. The top of the drive rod 213 is provided with a pressure plate 204 located on the outer side of the top of the baffle 202. The pressure plate 204 is parallel to the baffle 202. Locking plates 205 are symmetrically provided on both sides of the pressure plate 204. The locking plate 205 has a first locking hole 206 through which the locking bolt 3 is inserted. The bottom sides of the pressure plate 204 are symmetrically provided with insertion plates 212 that can be inserted into the first insertion slot 215.

[0037] The drive rod 213 is coaxially sleeved with a drive spring 219 located in the travel groove. One end of the drive spring 219 is connected to the travel block 218, and the other end of the drive spring 219 is connected to the inner side wall of the travel groove.

[0038] The traveling block 218 is provided with a moving block 209 extending to the outside of the baffle 202. The baffle 202 is provided with a moving groove 211 for the moving block 209 to move.

Within 3, the two cable tray bodies 1 are initially fixedly connected to the fastening assembly 2. Next, the displacement pushing block 207 causes the fastening rod 208 to disengage from the fastening hole 210, and the downward displacement moving block 209 causes the pressing plate 204 to move towards the baffle 202. The insertion plate 212 on the pressing plate 204 slides out from the first insertion groove 215 and inserts into the second insertion groove 104 of the guide plate 103. At the same time, the locking plates 205 on both sides of the pressing plate 204 are engaged into the locking grooves 105 of the cable tray body 1, so that the first locking hole 206 and the second locking hole 106 are connected. The locking bolt 3 is inserted into the connected first locking hole 206 and the second locking hole 106 for fixation, thus completing the docking installation between the two cable tray bodies 1. This utility model improves the connection strength and stability between two adjacent cable tray bodies 1.
