In the present embodiment, the number of the second fixing plates 34 is eight. Four second fixing plates 34 are provided in each of the second arc grooves 33.

A connecting rod 341 is provided between two adjacent second fixing plates 34 in the same second arc groove 33. Both ends of the connection rod 341 are fixed to one side of the corresponding second fixing plate 34.

The length of the transverse plate in the second fixing plate 34 is 0.8-0.9 times the distance between two adjacent first fixing plates 31 in the same first arc-shaped groove 32. In the present embodiment, the length of the transverse plate in the second fixing plate 34 is 0.8 times the length of the distance between two adjacent first fixing plates 31 in the same first arc-shaped groove 32.

A first guide rod 4 is horizontally arranged in each second arc-shaped groove 33, and the first guide rod 4 passes through a plurality of second fixing plates 34 in the same second arc-shaped groove 33.

The connecting assembly 3 further comprises two pushing assemblies 5, the positions of the pushing assemblies 5 correspond to the positions of the corresponding second arc-shaped grooves 33.

The pushing component 5 comprises a connecting block 51, a first through hole 52 is formed in one side of each of the two arc surfaces in the protective sleeve 2, the inside of the first through hole 52 is communicated with the inside of the corresponding second arc groove 33, the connecting block 51 is located in the corresponding first through hole 52, and one side of the connecting block 51 is fixed with one side of the corresponding riser in the second fixing plate 34.

The second guide rod 53 is horizontally arranged in the first through hole 52, the second guide rod 53 penetrates through the corresponding connecting block 51, the connecting block 51 is in sliding connection with the corresponding second guide rod 53, a push plate 54 is arranged on one side, away from the second fixing plate 34, of the connecting block 51, the push plate 54 covers the corresponding first through hole 52, one side of the push plate 54 is attached to the outer side of the protective sleeve 2, and anti-skidding patterns are machined on one side, away from the protective sleeve 2, of the push plate 54. During the movement of the push plate 54, the push plate 54 always covers the corresponding first through hole 52. The outer peripheral surface of the second guide rod 53 is sleeved with a first spring 6, and two ends of the first spring 6 are respectively fixed with one side corresponding to the inner wall of the first through hole 52 and one side corresponding to the connecting block 51.

Since the cross-sectional shape of the charging end 12 and the cross-sectional shape of the protective sleeve 2 are both special figures. When the charging end 12 enters the inside of the protective sleeve 2, and the first spring 6 is in a compression deformation state, the second fixing plate 34 naturally falls between the corresponding two first fixing plates 31. At this time, attention should be paid to the positional state of the connection block 51, and the connection block 51 should not be able to further compress the first spring 6 by continuing the movement.

At this time, the risers in the second fixing plates 34 are located between the corresponding two first fixing plates 31. And the transverse plate in the second fixing plate 34 is positioned between the bottom of the inner wall of the first arc-shaped groove 32 and the first fixing plate 31.

When the transverse plate in the second fixing plate 34 is positioned in the corresponding first arc-shaped groove 32 and the first spring 6 is in a natural state, the transverse plate in the second fixing plate 34 is attached to one side of the corresponding first fixing plate 31.

The implementation principle of the embodiment is as follows:

when an operator needs to use the charging gun body 1, the operator pushes two push plates 54 simultaneously, and the push plates 54 drive the corresponding connecting blocks 51, so that the connecting blocks 51 start to move, and the first springs 6 are driven to be in a compressed state. When the connection block 51 cannot be moved any more, the operator takes the protective cover 2 out of the charging end 12 while keeping the existing position of the connection block 51 unchanged. At this time, the second fixing plate 34 is located exactly between the corresponding two first fixing plates 31. (fig. 2 of the drawings is an exemplary diagram in which the positions of the connection block 51, the plurality of second fixing plates 34, and the first springs 6 are not accurate).

When the protective sheath 2 is separated from the charging end 12, the operator releases both push plates 54. Under the elastic restoring force of the first springs 6, the first springs 6 return to the initial position, and at this time, the plurality of second fixing plates 34 also move to the initial position.

After the charging gun body 1 is completed. The operator places the protective sheath 2 on the charging gun body 1.

First, the operator pushes the two push plates 54 to move the push plates 54, and the push plates 54 drive the corresponding connection blocks 51 to move. The connecting block 51 drives the corresponding second fixing plate 34 to move, and the second fixing plate 34 drives the rest of the second fixing plates 34 to move through the connecting rod 341.

The operator then holds the push plate 54 in place and places the protective sleeve 2 over the charging end 12. Since the cross-sectional shape of the charging end 12 and the cross-sectional shape of the protective sleeve 2 are both special patterns, care is not required to consider the direction of the protective sleeve 2.

When the charging end 12 is fully inserted into the protective sheath 2. At this time, the vertical plate in the second fixing plate 34 is located between the corresponding two first fixing plates 31, and the horizontal plate in the second fixing plate 34 is located below the first fixing plates 31.

The operator then releases both push plates 54. Under the action of elastic restoring force of the first spring 6, the first spring 6 drives the connecting block 51 to return to the initial position. And then the second fixing plates 34 corresponding to the second arc grooves 33 are returned to the initial positions. At this time, the side of the transverse plate of the second fixing plate 34 is attached to the side corresponding to the first fixing plate 31.

When the operator wants to clean the inside of the charging hole of the charging end 12, the protection sleeve 2 needs to be guaranteed to be connected with the charging end 12.

The operator rotates knob 8, and knob 8 drives corresponding connecting block 51 to rotate, and connecting block 51 drives corresponding rotation rod to rotate, and the rotation rod drives corresponding clearance portion to rotate. The cleaning part cleans the inside of the corresponding charging hole.

When the cleaning is completed, if the operator needs to replace the cleaning part, the operator takes out the protective sleeve 2 according to the method and replaces the cleaning part, and then installs the protective sleeve 2.

It is noted that the cleaning portion is shaped and sized to fit the internal shape and size of the charging end 12. An exemplary diagram is shown in fig. 5 of the accompanying drawings.

The embodiments of the present utility model are all preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
