In addition, the pressing structure 12 is provided with a connecting member 121 locked and/or separated from the locking channel 22, in this embodiment, the connecting member 121 and the pressing structure 12 are an integral structure, and the connecting member 121 moves along with the adjustment of the pressing structure 12, so that the connecting member 121 can be located in the locking channel 22 to be locked, or can be separated from the locking channel 22, and in other embodiments, the connecting member 121 and the pressing structure 12 can be a separate structure, or can be connected through other external parts, which all have the above functions.

As another embodiment of the present invention, as shown in fig. 3, a hollow chamber 111 is formed by being depressed inward from a part and/or the whole of the plug body 11.

Specifically, the pressing structure 12 is an independent structure, is not directly connected to the plug body 11, but moves relative to the hollow cavity 111, and compared with some existing plug connectors, most of the pressing structures are integrated structures of the pressing part and the plug body, so that the damaged part cannot be replaced or maintained, the whole pressing structure needs to be replaced or purchased again, the cost is high, and under long-time use, the pressing part and the plug body are easy to oxidize and break, and the practicability is not strong. The pressing structure 12 or the plug body 11 of the utility model is a split structure, so that the damaged structure can be replaced or maintained when damaged, and the whole structure does not need to be replaced or purchased. Further, in the present embodiment, the pressing structure 12 moves along the lateral direction of the hollow cavity 111, when the pressing structure 12 is adjusted inward and laterally, the connecting member 121 is far away from the locking channel 22, and the base unit 2 is separated from the plug unit 1, and similarly, when the pressing structure 12 is adjusted outward and laterally, the connecting member 121 is close to the locking channel 22, and the base unit 2 is locked with the plug unit 1, which is simple in structure and flexible in adjustment.

Specifically, in the present embodiment, the pressing structure 12 is partially located in the hollow chamber 111 for adjustment, and the other part is located outside for applying an acting force, so that the hollow chamber 111 of the present invention not only provides for adjustment of the pressing structure 12, but also accommodates the pressing structure 12, the space utilization is high, the structural arrangement is reasonable, and the pressing structure 12 is disposed along the longitudinal direction, thereby increasing the contact area of the pressing structure 12 in the hollow chamber 111, which is beneficial to maintaining the balance of the pressing structure 12 during adjustment, stabilizing the structure, and facilitating the application of a force. Furthermore, the longitudinal width of the pressing structure 12 is matched with the longitudinal width of the hollow chamber 111, so that the pressing structure 12 is exactly clamped in the hollow chamber 111 in the longitudinal width, thereby preventing the pressing structure 12 from longitudinally shaking during force application or use to influence the matching connection between the connecting member 121 and the locking channel 22, improving the stability, and having a firm and durable structure.

Specifically, in the present embodiment, the elastic structure 13 is provided as one, and in other embodiments, two, three or more elastic structures 13 may be provided, so that the elastic structure 13 is parallel to the hollow cavity 111 and is longitudinally located at the interval between the hollow cavity 111 and the pressing structure 12, so that when the pressing structure 12 is driven inward by an external force, the pressing structure 12 will press the elastic structure 13, and the resilience of the elastic structure 13 will drive the pressing structure 12 outward, thereby forming an adjustment. Furthermore, the elastic structure 13 is partially sleeved on the pressing structure 12, which is beneficial for firm and stable connection between the elastic structure 13 and the pressing structure 12, and certainly, the elastic structure 13 and the pressing structure 12 can be an integrated structure or a separate structure, and the elastic structure 13 can be a structure with resetting and rebounding functions, such as a spring, an elastic sheet, and the like. In addition, one end of the elastic structure 13 is connected to the pressing structure 12, and the other end of the elastic structure 13 abuts against and/or separates from the inner wall surface of the hollow chamber 111, or in other embodiments, one end of the elastic structure 13 abuts against and/or separates from the pressing structure 12, and the other end of the elastic structure is connected to the inner wall surface of the hollow chamber 111, so that when an external force acts on the pressing structure 12, the pressing structure 12 moves to the direction of the elastic structure 13 to deform through the elastic structure 13, and the adjustment is flexible during installation or use, the resetting performance is good, and a certain buffering effect is achieved.

As shown in fig. 7, as another embodiment of the present invention, the pressing structure 12 includes a pressing body 122, a driving member 123, a stopper member 124, and a connecting member 121. Specifically, the pressing body 122 is longitudinally disposed along the hollow cavity 111, or in some embodiments, the longitudinal width of the pressing body is matched with that of the hollow cavity 111, the driving member 123 laterally protrudes from an end surface of the pressing body 122, the driving member 123 can be pressed by a hand of a user, and has a force-receiving interface for applying an external force, the force-receiving interface facilitates the application of the external force by the user, so that a portion of the driving member 123 is located in the hollow cavity 111, another portion of the driving member is located outside, the limiting member 124 laterally protrudes from another end surface of the pressing body 122, the direction opposite to the direction in which the driving member 123 is disposed, and the connecting member 121 and the driving member 123 laterally protrude from the pressing body 122 at the same end surface. Therefore, in an actual adjustment process, when a user applies force to the driving member 123 to move laterally inward relative to the hollow chamber 111, the limiting member 124 gradually approaches the inner wall surface of the hollow chamber 111 until the limiting member 124 abuts against the inner wall surface of the hollow chamber 111 to limit the movement of the pressing structure 12, it should be noted that in this embodiment, the limiting member 124 is located above the driving member 123, in other embodiments, the limiting member 124 may be located at any position on the other end surface of the pressing body 122, that is, the limiting member 124 may also be located above the connecting member 121, and both have a constraint effect. Similarly, when the restoring force of the elastic structure 13 or the user applies force again to the driving member 123 to move laterally outward relative to the hollow cavity 111, the limiting member 124 gradually moves away from the inner wall surface of the hollow cavity 111, and the connecting member 121 gradually moves close to the locking channel 22, so that the plug unit 2 and the base unit 1 are locked together, and the outer end surface of the connecting member 121 is an arc surface, which is beneficial to flexible matching with the locking channel 22 and prevents jamming. In addition, the transverse width of the limiting member 124 and the pressing body 122 is smaller than the transverse width of the driving member 123 and the pressing body 122, so that the pressing structure 12 is prevented from completely entering the hollow cavity 111, the situation that the user cannot apply force to drive the pressing structure 12 is avoided, the structural design is humanized, and the practicability is improved. In the present embodiment, the driving member 123 and the stopper member 124 are provided as one, and in other embodiments, the driving member 123 and the stopper member 124 may be provided in two, three, or more, so that driving is facilitated or a stopper function is better.

In addition, the connecting member 121 can be matched and connected with the locking channel in the movement process of the first adjusting channel 112, so that the base unit 2 is locked with the plug unit 1, at the moment, the first adjusting channel 112 is communicated with the locking channel 22, and the connecting member 121 can penetrate through the first adjusting channel 112 to form locking in the locking channel 22, so that the first adjusting channel 112 is used for the movement of the connecting member 121, and the connecting member 121 is matched with the locking channel 22 in a certain range, and therefore, the flexibility is high, and the stability is good. As another embodiment of the present invention, the plug body 11 further has a second adjusting channel 113, in which the hollow chamber 111 is communicated with the outside, for the driving member 123 to move, and the position of the second adjusting channel 113 corresponds to the driving member 123, and the shape of the second adjusting channel is slightly larger than or corresponds to the shape of the driving member 123, so that when a user presses the driving member 123, the force is applied accurately and uniformly, and the second adjusting channel does not deviate, thereby saving labor and providing a good use feeling. It should be noted that, in the present embodiment, one adjusting channel 112 and one adjusting channel 113 are provided, and in other embodiments, two or more adjusting channels may be provided for adjusting the pressing structure 12 or for connecting with the base unit 2.

As shown in fig. 8, as another embodiment of the present invention, the plug body 11 is further provided with a supporting member 114, and the supporting member 114 is located between the first adjusting passage 112 and the second adjusting passage 113 for preventing the pressing structure 12 from being separated from the hollow chamber 111 when being adjusted outward. Specifically, in the present embodiment, the supporting member 114 is formed by the wall surface of the plug body 11 to block the hollow cavity 111 from the outside, during the actual adjustment process, when the pressing structure 12 is adjusted inward relative to the hollow cavity 111, the pressing structure 12 is far away from the supporting member 114, but when the pressing structure 12 is adjusted outward relative to the hollow cavity 111, that is, the connecting member 121 is located in the locking passage 22, and the base unit 2 is locked with the plug unit 1, the pressing structure 12 abuts against at least one end surface of the supporting member 114, which may be the pressing body 122 and/or the driving member 123 and/or the limiting member 124 abuts against at least one end surface of the supporting member 114, and the supporting member 114 has the supporting and limiting functions on the pressing structure 12, so as to prevent the pressing structure 12 from being separated from the hollow cavity 111 when being adjusted outward, and the structure is stable and practical.
