Connecting hole 92A2.Locking piece 92B also has first end (diagram right-hand member) and the second end (diagram left end).The first of locking piece 92B
End is provided with bullet part hole 92B1, and second end of locking piece 92B is provided with connecting hole 92B2.By second end of locking piece 92A is overlapped
At second end of locking piece 92B, and make connecting hole 92A2 and connecting hole 92B2 overlapped, then actuator 91 is inserted connection
In 92A2 and 92B2 of hole, thus locking piece 92A and locking piece 92B is connected into locking piece 92.
As shown in figure 9, actuator 91 front end is provided with stop portion 911 and gradually broadening from front end to tail end, so that
The plane projection approximate trapezoid of actuator 91, its front end is little, and tail end is big.The front end size of actuator 91 is than the company on locking piece 92
Connect the little of hole 92A2 and connecting hole 92B2, and tail end size is bigger than the connecting hole 92A1 on locking piece 92 and connecting hole 92B1, from
And when external force forces locking key 91 to move forward in connecting hole 92A1 and connecting hole 92B1, locking piece 92A and locking piece 92B
Simultaneously to middle mobile, thus the left and right two ends of locking piece 92 are respectively from the locking piece receiving opening (not shown) of side plate 2 and side plate 4
In exit.Thus realizing the unblock of side plate 3 and side plate 2 and side plate 4.
As shown in fig. 6, bullet part 63 includes bullet part 63A and bullet part 63B.Bullet part 63A is identical with bullet part 63B, all for a U-shaped
Part.Bullet part 63A carries fixed part 63A1 and elastic 63A2, and bullet part 63B carries fixed part 63B1 and elastic 63B2.Accordingly
Ground, is provided with fixed part installation position 33A and fixed part installation position 33B on side plate 3.Fixed part 63A1 and fixed part 63B1 pacifies respectively
It is loaded in the fixed part installation position 33A and fixed part installation position 33B of side plate 3, thus bullet part 63A and bullet part 63B is fixed respectively
On side plate 3.Elastic 63A2 and elastic 63B2 are respectively protruding in the bullet part hole 92A1 and bullet part hole 92B1 of locking piece 92,
Thus after locking piece 92 mobile unblock, elastic 63A2 and elastic 63B2 apply to locking piece 92 from two ends respectively and move
Power in opposite direction forces its reset.
During installation, first locking piece 92A and locking piece 92B is connected with each other by actuator 91.Then locking piece 92 is pacified
It is loaded in the locking piece installation portion (not) of side plate 3.Finally again bullet part 63A and bullet part 63B is passed through fixed part 63A1 and 63B1
Thus being installed to bullet part 63 on side plate 3 in the fixed part installation position 33A being installed on side plate 3 and fixed part installation position 33B, and
Its elastic 63A2 and elastic 63B2 is made to be respectively protruding in the bullet part hole 92A1 and bullet part hole 92B1 of locking piece 92.
During locking, bullet part 63A and bullet part 63B are respectively at undeformed state, the weight of connecting hole 92A1 and connecting hole 92B1
Folded part just be enough to accommodate the cervical region 912 of actuator 91, and now the two ends of locking piece 92 are respectively protruding into side plate 2 and side plate 4
Locking piece receiving opening (not shown) in.During unblock, promote actuator 91 forward, actuator 91 is to locking piece 92A and locking piece
92B applying power simultaneously, forces locking piece 92A and locking piece 92B to overcome the elastic force of bullet part 63A and bullet part 63B to act on and move in opposite directions
Dynamic, and make connecting hole 92A1 and connecting hole 92B1 lap become big, thus locking piece 92 two ends exit side plate 2 and side respectively
The locking piece receiving opening (not shown) of plate 4.After unblock terminates, locking piece 92A and locking piece 92B is bullet part 63A's and bullet part 63B
Under elastic force effect, each return to locking bit.Now, if side plate 2 and side plate 4 are all holded up and be in the locked position with side plate 3,
The two ends of locking piece 92 are stretched in side plate 2 and the locking piece receiving opening (not shown) of side plate 4 again, thus again by side plate 2
With side plate 4 mutually locking.
