Furthermore, during the installation of the chassis, the user can quickly and safely install or replace the chassis 1 without tools, making it extremely convenient to replace or upgrade the chassis 1 later.

[0052] like Figure 7-Figure 9As shown, the first limiting block 5 has an engaging groove 51 on one side close to the chassis 1 , and the engaging groove 51 matches with the engaging portion 11 .

[0053] By opening an engagement groove 51 on the first limiting block 5, the engagement groove 51 is used to cooperate with the engagement portion 11. When the chassis 1 is installed, the engagement portion 11 of the chassis 1 cooperates with the engagement groove 51 of the first limiting block 5, so that the rear end of the chassis 1 is limited on the rack 2 by the first limiting block 5, so as to fix the chassis 1 later.

[0054] A preferred method is as follows Fig. 9 As shown, the position of the engaging portion 11 corresponds to the position of the engaging groove 51 , ensuring that the engaging portion 11 and the engaging groove 51 can be accurately matched together when the chassis 1 is installed.

At this time, the pin 42 provides a locking force for pressing the chassis 1 backward, and the spanner 31 is not disengaged when being clamped by the trigger 33, thereby ensuring that the lock hook 32 and the pin 42 are hooked and locked, thereby completing the installation and fixing of the chassis 1 on the frame 2. At this time, the chassis 1 is fixed on the frame 2 through the cooperation of the locking handle 3 and the lock 4, and the cooperation of the first limit block 5 and the meshing portion 11;

[0065] When the chassis 1 is removed from the frame 2, the trigger 33 is pulled outward to separate the trigger 33 from the wrench 31, and then the wrench 31 is rotated counterclockwise to separate the lock hook 32 from the pin 42 and disengage from the grooved member 41. Fig.11 , and then the chassis 1 is taken out from the rack 2 by pulling the handle housing 34 .

[0066] A chassis assembly system of the present application can realize the rapid installation and removal of the chassis 1 on the rack 2 through the cooperation of the locking handle 3 and the lock 4, and the cooperation of the first limit block 5 and the engaging portion 11, thereby greatly improving the convenience of using and replacing the chassis 1.

[0067] In a preferred manner, the pin shaft 42 is detachably installed inside the groove member 41 .

[0068] Since the pin shaft 42 is detachably installed inside the grooved part 41, when the wrench 31 is not easy to rotate and the locking hook 32 and the pin shaft 42 cannot be separated, the locking handle 3 and the lock 4 can be separated by removing the pin shaft 42, thereby facilitating the removal of the chassis 1 from the frame 2.

[0069] In a preferred manner, the handle housing 34 is mounted on the chassis 1 by bolt connection.
