In this application, only by rotating the cam handle 4, the connection and locking of two lamp tubes can be realized, and the operation is simple and convenient. In some embodiments, the end of the locking rod 21 may not be provided with a second locking groove 211, and the end of the locking rod 21 is in a mushroom head shape.

[0030] See Figure 2, in some embodiments, the connecting rod 3 is disposed above the locking member 2, and a first surface 201 of the locking member 2 in contact with the connecting rod 3 is an inclined surface; the connecting rod 3 has a first protruding portion 302 protruding towards the locking member 2, and the first protruding portion 302 is in contact with the first surface 201. When the cam handle 4 drives the connecting rod 3 to slide, the first protruding portion 302 slides on the first surface 201. Since the first surface 201 is an inclined surface, the connecting rod 3 can push the locking member 2 downward (towards the locking hole 22) to insert the locking member 2 into the locking hole 22. In some embodiments, the first protruding portion 302 has an inclined second surface 3021 (see Figure 2 and Figure 4 ), and the inclination angle of the second surface 3021 is opposite to that of the first surface 201, and the first surface 201 is in contact with the second surface 3021. The setting of the inclined second surface 3021 makes the connecting rod 3 and the locking member 2 in surface-to-surface contact, and the force is more uniform.

[0031] In some embodiments, the locking member 2 is provided with a through first hole 202 so that when the lock base 20 is connected to the connecting lock 50, the lock rod 21 can pass through the locking member 2 from the first hole 202 and then insert into the locking hole 301. The first surface 201 has a first end 2011 and a second end 2012 opposite to the first end 2011. The first end 2011 is higher than the second end 2012. The first end 2011 corresponds to the insertion section 3011, and the second end 2012 corresponds to the connection section 3012. When the cam handle 4 is parallel to the fixed seat 1, the lock rod 21 is located in the connection section 3012, and the connecting rod 3 is in contact with the first end 2011, that is, the locking member 2 is inserted into the locking hole 22. When the cam handle 4 is rotated upward to be perpendicular to the fixed seat 1, the lock rod 21 is located in the insertion section 3011, and the connecting rod 3 corresponds to the second end 2012 of the first surface 201, that is, the locking member 2 is pulled out of the locking hole 22. The first end 2011 corresponds to the insertion section 3011 so that when the connecting rod 3 is in contact with the first end 2011, the lock rod 21 is in the connection section 3012. The second end 2012 corresponds to the connection section 3012 so that when the connecting rod 3 is in contact with the first end 2011, the lock rod 21 is in the insertion section 3011.

[0032] In some embodiments, the connection lock 50 further includes a first elastic member 6 and a cover plate 7. The cover plate 7 is fixedly connected to the fixed seat 1 by screws.
