Under the condition that the locking piece 30 is in the locking state, the limiting structure 32 is connected with the locking structure 45 so as to lock the guide sleeve 42; with the lock 30 in the unlocked state, the limit structure 32 is disengaged from the lock structure 45 to unlock the guide sleeve 42.

Set up spacing boss 31 on the outer wall of locking piece 30, be provided with limit structure 32 on the spacing boss 31, be provided with spacing groove 1311 along the direction of the second face to first face of casing 10 on the pore wall of first mounting hole 131, and when first mounting hole 131 switched on through spacing groove 1311 with second mounting hole 132, at this moment, spacing boss 31 was located spacing groove 1311, make locking piece 30 can't rotate, locking piece 30 can only follow the direction removal of second face to first face, locking piece 30 can't rotate promptly, can only follow the axial direction removal of self. That is, the locking member 30 is limited by the cooperation of the limiting boss 31 and the limiting groove 1311, so that the locking member 30 is prevented from rotating. In addition, when the locking member 30 moves along the axial direction of the locking member 30, the state of the locking member 30 can be changed, and when the locking member 30 is in the locking state, the limiting structure 32 is connected with the locking structure 45, which is equivalent to the connection between the guide sleeve 42 and the locking member 30, and because the locking member 30 cannot rotate, the guide sleeve 42 cannot rotate, and the guide sleeve 42 is locked; when the lock member 30 is in the unlocked state, the stopper 32 is separated from the lock structure 45, which means that the guide bush 42 is separated from the lock member 30, and at this time, the guide bush 42 is unlocked by the lock member 30, so that the guide bush 42 can be rotated.

It should be noted that, in the embodiment of the present invention, the limiting boss 31 may be disposed along the axial direction of the locking member 30. In addition, in the embodiment of the present invention, the position-limiting structure 32 is adapted to the locking structure 45, that is, the position-limiting structure 32 is different according to the locking structure 45. For example, when locking structure 45 is the toper tooth, this moment, limit structure 32 can be the skewed tooth, and skewed tooth and tapered tooth can mesh, and when locking structure 45 was the joint groove, this moment, limit structure 32 can be the joint boss, and the joint boss can the joint in the joint groove.

In addition, in some embodiments, as shown in fig. 2, one end of the locking member 30 is a closed end, and the locking member 30 is provided with an elastic member 50. One end of the elastic member 50 contacts the closed end of the locking member 30, and the other end of the elastic member 50 contacts the bottom of the second mounting hole 132. When the elastic member 50 is in a compressed state by pressing the closed end of the locking member 30, the locking member 30 is in an unlocked state; when the closed end of the lock member 30 is released from the pressing and the elastic member 50 returns to the original state, the lock member 30 is in the locked state.

When the one end of retaining member is the blind end, sets up elastic component 50 in the locking member 30, the one end of elastic component 50 and the blind end contact of locking member 30, when the other end of elastic component 50 and the hole bottom contact of second mounting hole 132, at this moment, can press locking member 30 through the blind end for locking member 30 moves along the axial direction of locking member 30, and then makes the state change of locking member 30. When the closed end of the locking member 30 is pressed and the elastic member 50 is in a compressed state, at this time, the limiting structure 32 can be separated from the locking structure 45, so that the locking member 30 is in an unlocked state, and the locking member 30 releases the locking of the guide sleeve 42; when the closed end of the locking piece 30 is released from pressing, the elastic piece 50 is restored to the initial state from the compression state due to the elastic action of the elastic piece 50, the elastic piece 50 drives the locking piece 30 to move in the restoration process of the elastic piece 50, and at the moment, the limiting structure 32 is connected with the locking structure 45, so that the locking piece 30 is in the locking state, the locking piece 30 is further enabled to lock the guide sleeve 42, and the guide sleeve 42 is enabled not to rotate. That is, by providing the elastic member 50 in the locking member 30, and contacting both ends of the elastic member 50 with the closed end of the locking member 30 and the bottom of the second mounting hole 132, respectively, it is possible to facilitate switching of the state of the locking member 30.

When fastening components include baffle 60, baffle 60 sets up the second face at fixed plate 11, third through-hole 61 has been seted up on the baffle 60, third through-hole 61 corresponds with first mounting hole 131 position, the aperture of third through-hole 61 is less than the external diameter of second cooperation limit structure 44, the aperture of fourth through-hole 62 is less than or equal to the external diameter of locking piece 30, consequently, when fastener 41 drops from uide bushing 42, second cooperation limit structure 44 can be blockked by baffle 60, thereby block fastener 41, avoid fastener 41 to drop from the uide bushing 42. In addition, the baffle 60 is further provided with a fourth through hole 62, and the fourth through hole 62 corresponds to the second mounting hole 132, so that when the closed end of the locking piece 30 needs to be pressed, the pressing piece can be pressed against the closed end of the locking piece 30 after penetrating through the fourth through hole 62, and the locking piece 30 can be pressed. That is, the third through hole 61 and the fourth through hole 62 are formed in the blocking plate 60, so that the blocking plate 60 blocks the fastening member 41 and the locking member 30 can be easily pressed.

It should be noted that the baffle plate 60 may be connected to the second surface of the fixing plate 11 by bolts, of course, the baffle plate 60 may also be connected to the second surface of the fixing plate 11 by pins, or may also be connected to the second surface of the fixing plate 11 by welding, and the embodiment of the present invention is not limited herein as to the way that the baffle plate 60 is disposed on the second surface of the fixing plate 11.

In addition, in some embodiments, as shown in fig. 1 and fig. 2, a mounting table 14 is disposed on the second fixing table 13, a guide hole is opened on the mounting table 14, the fastening member 41 is inserted through the guide hole, and at least a portion of the fastening member 41 is located outside the guide hole, a mounting member 15 is disposed on an outer wall of the mounting table 14, and the mounting member 15 is used for connecting the battery with the second fixing table 13.

Because the installation platform 14 is arranged on the second fixing platform 13, the installation platform 14 is provided with a guide hole, the fastener 41 penetrates through the guide hole, and at least part of the fastener 41 is positioned outside the guide hole, when the battery is connected with the vehicle through the fastener 41, the installation platform 14 cannot influence the fastener 41, and further influence the connection of the battery and the vehicle through the fastener 41. Since the mounting member 15 is disposed on the outer wall of the mounting table 14, the battery can be connected to the second fixing table 13 through the mounting member 15, so that the connection between the battery and the fastening assembly is more secure.

It should be noted that the mounting member 15 may be a nut, and the outer wall of the mounting table 14 may be provided with a thread, and at this time, the nut may be rotated to mount the nut on the outer wall of the mounting table 14. Of course, the mounting member 15 may be other devices, such as a snap, for example, and the embodiment of the present invention is not limited thereto.

In addition, in the embodiment of the present invention, one end of the mounting table 14 may be connected to the second fixing table 13, and an end surface of the other end of the mounting table 14 may be flush with an end surface of the first fixing table 12 at an end not connected to the fixing plate 11.
