A rubber anti-slip pad 5 is fixedly installed on the inner wall of the locking groove 102 inside the fixing block 101. The rubber anti-slip pad 5 can increase the friction between the fixing block 101 and the lower frame of the module, thereby making the connection between the fixing block 101 and the lower frame of the module more stable.
