Referring to <FIG>, the plug storage base <NUM> comprises a connecting body <NUM> and at least two storage structures <NUM> disposed on the connecting body <NUM>. Each storage structure <NUM> comprises a mounting recess <NUM> provided in the connecting body <NUM> and a stop block <NUM> connected to a recess wall of the mounting recess <NUM>, the mounting recess <NUM> is provided along in an extension direction, the mounting recess <NUM> is configured to store the plugging structure <NUM>, and the stop block <NUM> can be adapted to and plugged in the plugging structure <NUM>. Preferably, the stop block <NUM> can divide the mounting recess <NUM> into two separate slots each adapted to one of the fasteners <NUM>, and the connecting block is adapted to and plugged in the stop block <NUM>. In this embodiment, three storage structures <NUM> are provided to store three detachable plugs <NUM>. Preferably, the multiple mounting recesses <NUM> are spaced apart from each other so as to prevent the multiple detachable plugs <NUM> from interfering with each other during installation.

An inner wall surface of the mounting recess <NUM> has a bottom surface, a slot back surface that is opened in an extension direction of the mounting recess, and two slot side surfaces located on two sides of the opening in the extension direction of the mounting recess. Referring to <FIG> and <FIG>, in order to achieve alignment of the pluggable plug and the mounting recess <NUM>, the recess wall of the mounting recess <NUM> is provided with a first slide connection structure <NUM> for slide connection with the plugging structure <NUM>. Accordingly, this plug storage base <NUM> is suitable for detachable plugs <NUM> each provided with a second slide connection structure <NUM> that is adapted and in slide connection with the first slide connection structure <NUM>. One first slide connection structure <NUM> may be provided and is arranged on a slot side surface of the mounting recess <NUM> and extends in an extension direction of the mounting recess <NUM>, or two first slide connection structures <NUM> may be provided and are respectively arranged on both slot side surfaces of the mounting recess <NUM> so as to have a function of stopping the plugging structure <NUM> on both sides. Optionally, the first slide connection structure <NUM> may be a sliding block, and the second slide connection structure <NUM> is a slide connection slot. In this embodiment, the first slide connection structure <NUM> is a slide connection slot, and the second slide connection structure <NUM> is a sliding block. This can avoid affecting the structural stability of a socket. The slide connection slot may be adapted to the sliding block, and the slide connection slot may have a width greater than that of the sliding block, as long as a side surface of the slide connection slot facing the bottom of the mounting recess <NUM> can fit to the sliding block when the connecting block is plugged with the stop block <NUM>.

According to the present invention, at least two storage structures <NUM> are provided to provide mounting locations for at least two detachable plugs <NUM>, the plugging structure <NUM> of each of the detachable plugs <NUM> can be stored in the mounting recess <NUM> of one storage structure <NUM>, the recess wall of the mounting recess <NUM> is provided with the first slide connection structure <NUM>, and the plugging structure <NUM> can slide into the mounting recess <NUM> by means of the first slide connection structure <NUM> so as to achieve the function of guiding the plugging structure <NUM> and implement connection to the plug storage base <NUM>. The first slide connection structure <NUM> is disposed on the recess wall of the mounting recess <NUM> and thus can stop the detachable plugs <NUM> in the direction perpendicular to the extension direction of the mounting recess, so as to prevent the detachable plugs <NUM> from being separated from the plug storage base <NUM> in the direction perpendicular to the extension direction of the first slide connection structure <NUM>, so that the plug storage base <NUM> can store at least two detachable plugs <NUM> and is convenient to carry, so as to prevent the occurrence of easy losing of multiple detachable plugs <NUM> when being placed separately.

Referring to <FIG> and <FIG>, in order to prevent the detachable plugs <NUM> from accidentally sliding out of the mounting recesses <NUM>, the plug storage base <NUM> further comprises a first engaging structure <NUM> for clamped with the plug body <NUM>. Accordingly, the plug storage base <NUM> is suitable for detachable plugs <NUM> each provided with a second engaging structure <NUM> that is adapted and clamped with the first engaging structure <NUM>. In this way, the detachable plug <NUM> can only be detached from the mounting recess <NUM> by an external force, so as to prevent the detachable plug <NUM> from being lost. Optionally, the first engaging structure <NUM> may be a bump, and the second engaging structure <NUM> may be an engaging slot adapted to the bump. In this embodiment, the first engaging structure <NUM> is an engaging slot, and the second engaging structure <NUM> is a bump. The engaging slot is provided in the side of the stop block <NUM> that faces away from the bottom of the mounting recess <NUM> so as to achieve engaging and fitting with the plug body <NUM>. In other embodiments, the plug storage base without the first engaging structure <NUM> may also be suitable for a detachable plug <NUM> each provided with a bump. In this case, the slide connection and fitting between the first slide connection structure <NUM> and the second slide connection structure <NUM> is implemented by the stop block <NUM> or/and the plug body <NUM> through elastic deformation, and the bump and the stop block <NUM> elastically abut together through a friction force under the action of an external force, so as to implement fastening and connection between the detachable plugs <NUM> and the plug storage base <NUM>.

The connecting body <NUM> has a first connecting surface, a second connecting surface and a third connecting surface. The second connecting surface faces away from the third connecting surface, the first connecting surface is connected to the second connecting surface and the third connecting surface, and referring to <FIG>, one of the storage structures <NUM> further comprises an accommodating recess <NUM> provided in the first connecting surface and configured to store the plug body <NUM>, and the mounting recess <NUM> is provided in the recess wall of the accommodating recess <NUM> and has an opening on the first connecting surface. The accommodating recess <NUM> can be adapted to the plug body <NUM> when the plugging structure <NUM> is in plugged with the stop block <NUM> so as to prevent the plug body <NUM> from shaking when being bumped and thus prevent loosened connection between the plugging structure <NUM> and the stop block <NUM> caused by the shaking of the plug body <NUM>. A side wall of the accommodating recess <NUM> is closed to protect the detachable plugs <NUM> from being bumped. In addition, the pins <NUM> of the plug body <NUM> can be stored in the accommodating recess <NUM>.

Referring to <FIG>, preferably, the accommodating recess <NUM> has an opening on the second connecting surface. In this way, in one direction, the detachable plug <NUM> can be mounted to the accommodating recess <NUM>, and in the other direction, the detachable plug <NUM> is taken out from the accommodating recess <NUM>.

Referring to <FIG>, the mounting recess <NUM> may be provided in a side wall of the accommodating recess <NUM> that faces the second connecting surface. In this way, each detachable plug <NUM> can be plugged into the accommodating recess <NUM> in the direction of the first connecting surface, so that the plugging structure <NUM> of the detachable plug is inserted into the stop block <NUM> and accommodated in the mounting recess <NUM>. A user moves the plug body <NUM> from the opening of the accommodating recess <NUM> in the second connecting surface.

Optionally, the mounting recess <NUM> is provided in a side wall of the accommodating recess <NUM> perpendicular to a connecting line between the second connecting surface and the third connecting surface. In this way, the user performs the moving operation from a side of the plug body <NUM>.

Referring to <FIG>, preferably, the accommodating recess <NUM> has an opening on the second connecting surface and the third connecting surface. In this way, the storage structure <NUM> avoids the opposite sides of the plug body <NUM>, so that the user can hold the plug body <NUM> from two side surfaces of the plug body <NUM>.

Referring to <FIG> and <FIG>, pins <NUM> of the detachable plugs <NUM> are preferably collapsible so as to reduce the space occupied thereby, and referring to <FIG>, the plug storage base <NUM> is adapted to the detachable plugs, and one of the storage structures <NUM> further comprises an avoidance groove <NUM> communicating with the accommodating recess <NUM>. Since there are usually two pins <NUM> of the detachable plug <NUM>, two avoidance grooves <NUM> may be provided, and the two avoidance grooves <NUM> are arranged in parallel and spaced apart to respectively receive the pins <NUM>.

There are many ways of fixing the stop block <NUM> in the mounting recess <NUM>. Preferably, the stop block <NUM> extends in the same direction as the extension direction of the mounting recess <NUM> so as to facilitate machining.

Referring to <FIG>, since a connecting block is provided between two fasteners <NUM>, in order to implement plugging to the connecting block, the stop block <NUM> is provided with a limiting slot in an end face of the stop block in an extension direction thereof, and the connecting block can be inserted in the limiting slot to prevent the detachable plug <NUM> from being loosened from the side.

Since the connecting block is usually connected to a side wall of the plugging body, with the protruding direction thereof being perpendicular to the extension direction, in order to adapt to the plugging structure <NUM>, the limiting slot is extended toward the opening direction of the mounting recess <NUM>, so that the connecting block can be plugged in the limiting slot of the stop block <NUM> when the plugging structure <NUM> slides in from the opening of the mounting recess <NUM> in the extension direction.

The limiting slot sequentially comprises a limiting section and a connecting section in the extension direction of the limiting slot, and the slot width of the connecting section is smaller than that of the limiting section, so as to adapt to the structure of the connecting block. In this way, the connecting section achieves the function of limiting the connecting block in the opening direction of the mounting recess <NUM>, thereby preventing the connecting block from being separated from the limiting section.

In order to implement the tight connection between the storage structure <NUM> and the detachable plug <NUM>, the limiting slot is in an interference-fit with the plugging structure <NUM>, and since the fastener <NUM> of the plugging structure <NUM> is of a hollow structure, certain elastic deformation can be generated so as to achieve abutting with the storage structure <NUM> under the action of friction force.

Referring to <FIG>, in order to facilitate the carrying of the plug storage base <NUM>, the plug storage base <NUM> is further provided with a through hole <NUM>, and the user can pass a string through the through hole <NUM> to fix the plug storage base <NUM> to other parts for easy access and carrying.

Referring to <FIG> and <FIG>, the present invention further provides a plug kit, comprising detachable plugs <NUM> and a plug storage base <NUM> provided by the foregoing embodiments. The plug storage base <NUM> has the same structural features and functions as the plug storage base <NUM> in the foregoing embodiments, and will not be repeated here.

Referring to <FIG>, each detachable plug <NUM> comprises a plug body <NUM>, a plugging structure <NUM>, a second slide connection structure, and a second engaging structure. The plugging structure <NUM> of the detachable plug <NUM> comprises two fasteners <NUM> and a connecting block located between the two fasteners <NUM>. A plugging body is provided with two or three pins <NUM>, and the pins <NUM> are rotatably connected to the plug body <NUM> and can be collapsed or splayed. The plugging body <NUM> is provided with two or three pins <NUM>, and the pins <NUM> are rotatably connected to the plug body <NUM> and can be collapsed or splayed. The pins <NUM>, <NUM> may be pins conforming to British standards, European standards or American standards.

Referring to <FIG>, the second slide connection structure <NUM> is disposed on the side of one of the fasteners <NUM> that faces away from the other fastener <NUM> so as to implement the slide connection and fitting with the first slide connection structure <NUM>. Preferably, two second slide connection structures <NUM> may be provided, and the two second slide connection structures <NUM> are respectively disposed on the two sides of the two fasteners <NUM> that face away from each other. When the first slide connection structure <NUM> is a slide connection slot, the second slide connection structure <NUM> is a sliding block, and the sliding block is elongated and extends in the extension direction of the mounting recess <NUM>, so as to implement quick and stable connection with the slide connection slot. Preferably, the sliding block has a beveled surface for guiding, so as to implement quick docking with the slide connection slot. A portion of the sliding block that faces away from the beveled surface is provided with a stop protrusion to limit the fitting length of the detachable plug <NUM> and the plug storage base <NUM>.

Referring to <FIG>, the second engaging structure <NUM> can be clamped with the first engaging structure <NUM> when the plugging structure <NUM> is received in the mounting recess <NUM>, so as to prevent the detachable plugs <NUM> from being accidentally separated from the plug storage base <NUM> and further prevent the detachable plugs <NUM> from being lost. The second engaging structure <NUM> is disposed on the plug body <NUM> and located between the two fasteners <NUM> and preferably on the connecting block, so as to achieve engaging and fitting with the first engaging structure <NUM> on the stop block <NUM>. When the first engaging structure <NUM> is an engaging slot, the second engaging structure <NUM> is a bump which is adapted to the engaging slot. This has a function of limiting the plug body <NUM>, so that the detachable plugs <NUM> can be separated from the plug storage base <NUM> only when the bump moves out of the engaging slot under the action of an external force. One first engaging structure <NUM> and one second engaging structure <NUM> may be provided, or multiple first engaging structures and multiple second engaging structures may be provided, which is not limited herein.
