Description

Electric anastomat
Technical Field
The invention relates to the field of medical appliances, in particular to an electric anastomat.
Background
In the prior art, a power supply control device of an electric anastomat and the electric anastomat are provided, and the patent document with the application number of 202111462941.3 is provided; in the prior art, the power supply control device is provided with the pressing piece and the triggering piece, and the blocking cooperation of the pressing piece and the triggering piece ensures that the control switch assembly can not return to reset after the power supply is used once, so that the power supply of the electric anastomat is prevented from being reused.
However, the above prior art does not explain the principle of preventing the secondary use of the power supply, and from the paragraph 0044, the control switch assembly includes a pressing member capable of being pressed from a first position to a second position, the pressing member being located at the first position to restrict the movement of the triggering member to the triggering position, and the pressing member being located at the second position, the triggering member being capable of being moved from the initial position to the triggering position to drive the pressing control portion to the circuit-on position;
that is, it is judged from the standpoint of those skilled in the art that the pressing member has two functions, the first function, the locking trigger, the second function, the release trigger, and only one of the functions of the trigger is to drive the pressing control portion to be in communication with the electric circuit. Therefore, in the above prior art, after the power supply is used once, the pressing member and the triggering member are respectively unable to reset, so that the control switch assembly including the pressing member and the triggering member cannot be reset, but if the used power supply is connected to the electric stapler again, the pressing member and the triggering member in the power supply still maintain the triggered state, that is, the pressing member still maintains the state of releasing the triggering member, and the triggering member still maintains the state of driving the pressing control part to be connected with the circuit, thereby electrically conducting the circuit of the power supply with the motor of the electric stapler again, and thus the technical effect of 'preventing the power supply of the electric stapler from being reused' described in the above prior art cannot be achieved;
the inventor believes that, because the pressing piece and the triggering piece cannot be reset, the visual effect is used for reminding a user that the power supply is used, but the reminding effect is different from the use preventing effect, and the prior art only has the reminding effect and cannot prevent the user from installing the used battery pack on the electric anastomat again.
The prior art also provides a battery pack safety control method and system and an electric anastomat thereof, and the patent document with the application number of 202310511498.7; in the prior art, a mode of calculating the use times of the battery pack is adopted, and under the condition of meeting the preset use times, the battery pack is cut off from supplying power to the outside (a motor of an electric anastomat);
in the prior art, the technical effect obtained by the method is that the battery pack is prevented from being supplied with power to the outside when being reused, so that the waste battery pack is prevented from being reused; however, the above prior art solutions still do not prevent the user from mounting the 'discarded' or 'used' battery pack on the electric stapler, and after the user again mounts the 'discarded' or 'used' battery pack on the electric stapler, the battery pack and the electric stapler form a mechanical connection, and only the power supply circuit of the battery pack is cut off.
From all the above prior art, there is no technical solution available in the prior art that 'prevents the used battery pack from being reused', i.e. the battery pack of the known prior art, even if it is used once, the used battery pack can still be mounted on the electric stapler by means of a mechanical connection; therefore, how to provide a mechanical structure capable of preventing a used battery pack from being mounted on an electric stapler in a mechanically connected manner is a technical problem to be solved.

Detailed Description
In this context, a specific provision is made for an electric stapler, in which a safety assembly is provided in a battery pack, and a plug is provided on the electric stapler; the electric stapler herein differs most from the prior art in that: a mechanical structure comprising a plug and a safety component is adopted for preventing the used battery pack from being mounted on the electric anastomat again in a mechanical connection mode, namely, after the battery pack is used once, if a user mounts the used battery pack on the electric anastomat again, the used battery pack is blocked by the plug and the safety component, so that the used battery pack cannot be mounted on the electric anastomat in a mechanical connection mode.
The electric stapler herein will be described in detail by way of examples.
Example 1
In this embodiment, referring to fig. 1, 2, 3, 7 or 12, there is provided an electric stapler including a gun body 1, a plug 2 and a battery pack 3;
the plug 2 is fixedly or detachably connected to the gun body 1, and the plug 2 is detachably connected with the battery pack 3, wherein the plug 2 is configured to be inserted into the battery pack 3;
the direction in which the plug 2 is inserted into the battery pack 3 is defined as a first direction along which the stroke in which the plug 2 is inserted into the battery pack 3 is configured to be a first stroke and a second stroke, the length of which is greater than the length of the first stroke;
the plug 2 is provided with a first conductive sheet 201, the battery pack 3 is internally provided with a second conductive sheet 301 and a safety component 4, wherein the safety component 4 has an initial state and a limit state, and the plug 2 is used for controlling the safety component 4 to be converted from the initial state to the limit state;
when the safety assembly 4 is in the initial state, the stroke of the plug 2 inserted into the battery pack 3 may satisfy the second stroke, and the first conductive sheet 201 and the second conductive sheet 301 may contact each other;
when the safety assembly 4 is in the limit state, the plug 2 is blocked by the safety assembly 4, the stroke of the plug 2 inserted into the battery pack 3 is limited to the first stroke, and the first conductive sheet 201 and the second conductive sheet 301 are not in contact with each other.
It should be understood that the electric stapler of the present embodiment comprises, in addition to the aforesaid gun body 1, plug 2 and battery pack 3, an end effector, a gun barrel, a transmission mechanism and a motor; wherein the motor and the battery pack 3 can be configured to be electrically conducted, and a switch is arranged between the motor and the battery pack 3 and is used for being controlled by a user to enable the motor and the battery pack 3 to form an electric cut-off or electric conduction state; the power of the motor is output to the transmission mechanism, one part of the transmission mechanism is accommodated in the gun body 1, the other part of the transmission mechanism is accommodated in the gun barrel, the transmission mechanism has the function of converting the rotation action of a motor shaft of the motor into the forward action and the backward action in the linear direction, and the transmission mechanism respectively transmits the power of the forward action and the power of the backward action to the end effector; the end effector can perform closing or opening actions after receiving the power of the transmission mechanism; in this embodiment, the end effector, barrel, transmission mechanism, motor, etc. may be configured as in the prior art, for example: in the prior art (an electric stapler power supply control device and an electric stapler, application number 202111462941.3), its execution assembly corresponds to the end effector in this embodiment, its connection tube corresponds to the barrel in this embodiment, and its driving motor corresponds to the motor in this embodiment; in addition, in the prior art (a manual retraction device for an electric stapler and an electric stapler thereof, application number 202010057399.2), a combined structure of a transmission unit rack, an intermediate gear, a gear shaft, a motor gear and the like corresponds to a transmission mechanism in the present embodiment.
In this embodiment, the gun body 1 and the plug 2 are fixedly connected or are in a detachable connection structure; the detachable connecting structure is preferably adopted, so that the structure of the gun body 1 is simpler, and the die cost for manufacturing the gun body 1 is reduced; the plug 2 is manufactured independently, which is favorable for reforming the electric anastomat in the prior art, on one hand, when the electric anastomat in the prior art adopts the plug 2 in the embodiment, only a corresponding interface (a connecting structure, such as a clamping groove) is needed to be reformed on the original gun body 1, so that the reforming cost of the die of the gun body 1 in the prior art is relatively low. In addition, after the gun body 1 is connected with the plug 2, the first conductive sheet 201 on the plug 2 should be capable of transmitting electric energy into the gun body 1, specifically, one end of the first conductive sheet 201 may penetrate through the plug 2 to reach into the gun body 1, or an extending conductive member, such as a wire, may be provided on the plug 2, and the conductive member penetrates through the plug 2 and extends into the gun body 1. The first conductive piece 201 of the plug 2 and the motor in the gun body 1 may be configured to be electrically connected, which is known to those skilled in the art, and will not be described herein.
In this embodiment, referring to fig. 7 or 12, the battery pack 3 is used to supply power to the motor in the gun body 1; specifically, the second conductive piece 301 provided on the battery pack 3 can be configured to be in contact with the first conductive piece 201 of the plug 2, and when the first conductive piece 201 and the second conductive piece 301 are in contact with each other, the electric power of the battery pack 3 is supplied to the motor in the gun body 1 through the second conductive piece 301 and the first conductive piece 201.
In this embodiment, the safety component 4 in the battery pack 3 has two functions;
the first effect is that, when the plug 2 is inserted into the battery pack 3 for the first time, the safety assembly 4 cannot block the plug 2 (see fig. 2), thereby enabling the first conductive sheet 201 and the second conductive sheet 301 to contact each other; this is the case for simulating the first connection of the battery pack 3 with the plug 2, i.e., simulating the scenario in which the battery pack 3 is used for the first time;
the second function is that the safety module 4 can block the plug 2 (see fig. 3) so that the first conductive sheet 201 and the second conductive sheet 301 cannot contact each other when the plug 2 is inserted into the battery pack 3 for the second or third time … … or nth time; this is the case when the plug 2 is blocked by the safety member 4 so that the first and second conductive sheets 201 and 301 cannot contact each other when the analog battery pack 3 is mounted to the electric stapler again after being used once.
The first technical problem in this embodiment is created by the two effects of the safety assembly 4 described above: how to control the safety assembly 4 to block or not block the plug 2.
In the present embodiment, the insurance component 4 is configured with two use states: the first is an initial state (see the safety assembly 4 in fig. 2), that is, a state that the safety assembly 4 should have before the battery pack 3 is used for the first time; the second is a limit state (see the safety component 4 in fig. 3), that is, a state that the safety component 4 should have after the battery pack 3 is used for the first time and before the battery pack 3 is used for the second time;
the profile of the safety assembly 4 as a whole, when the safety assembly 4 is in the initial state, is not associated with the stroke of the plug 2 inserted into the battery pack 3, i.e. the profile of the safety assembly 4 as a whole is not associated with the first stroke and the second stroke, which allows the stroke of the plug 2 to satisfy the first stroke and the second stroke when the plug 2 is inserted into the battery pack 3, and in particular, allows the first conductive sheet 201 and the second conductive sheet 301 to be in contact with each other when the stroke of the plug 2 satisfies the second stroke; therefore, when the safety component 4 is in the initial state, the safety component 4 is restricted to 'not prevent' the plug 2;
when the safety assembly 4 is in the limit state, a part of the profile of the safety assembly 4 interferes with the stroke of the plug 2 inserted into the battery pack 3, i.e. a part of the profile of the safety assembly 4 is not associated with the first stroke, but a part of the profile of the safety assembly 4 is associated with the second stroke, which allows the stroke of the plug 2 to satisfy the first stroke but not the second stroke when the plug 2 is inserted into the battery pack 3, because the plug 2 is blocked by a part of the profile of the safety assembly 4 when the stroke of the plug 2 is shifted from the first stroke to the second stroke.
In the case where the above-described fuse assembly 4 has two states (an initial state and a limit state), a second technical problem in the present embodiment is formed: how the control safety component 4 is controlled to move from the initial state to the limit state;
in the embodiment, the plug 2 is adopted to control the safety component 4 to be switched from the initial state to the limit state; specifically, referring to fig. 2, when the plug 2 is inserted into the battery pack 3, a part of the structure of the plug 2 can contact the safety component 4, so that the safety component 4 can be converted from the initial state to the limit state under the action of the acting force of the plug 2 by the safety component 4;
it should be appreciated that the safety assembly 4 itself may be provided in a variety of configurations, and in the following, a preferred specific configuration of the safety assembly 4 will be provided and will not be discussed herein.
In the prior art (an electric stapler power supply control device and an electric stapler, application number 202111462941.3), although a pressing piece is provided, the pressing piece is displayed on the surface of the power supply, and the hand of a user can directly contact and press the pressing piece; in this embodiment, the safety component 4 is disposed inside the battery pack 3, so that the hand of the user cannot directly contact the safety component 4, and meanwhile, the plug 2 needs to replace the hand of the user to contact the safety component 4, so as to achieve the purpose of controlling the safety component 4 to transition from the initial state to the limit state; therefore, the positional relationship and technical principle of the plug 2 and the fuse assembly 4 with respect to the battery pack 3 in the present embodiment are respectively different from those of the pressing member of the related art with respect to the power source thereof.
In the prior art (a method, a system and an electric anastomat for controlling the safety of the battery pack 3, application number 202310511498.7), no mechanical structure similar to the safety component 4 in the embodiment is adopted, and the prior art adopts an electronic control mode to realize the purpose of cutting off the power supply of the battery pack 3 to the outside; the safety component 4 in the embodiment adopts a control mode of a mechanical structure to prevent the stroke of the plug 2 from meeting the second stroke, so as to achieve the purpose that the first conductive sheet 201 of the plug 2 and the second conductive sheet 301 in the battery pack 3 are not contacted with each other; therefore, the purpose and principle of the plug 2 and the safety module 4 in the present embodiment are different from those of the electronic control method in the related art, respectively.
In all the previous prior art, no mechanical structure is provided to prevent the power supply or battery pack 3 from being mounted on the electric stapler; in the present embodiment, the plug 2 is matched with the safety component 4 in the battery pack 3, so that when the battery pack 3 after being used once is mounted on the electric stapler again, the plug 2 is blocked by the safety component 4, and the technical effect that the battery pack 3 cannot be mounted on the electric stapler again is achieved.
Therefore, the electric stapler of the present embodiment solves the technical problem of how to provide a mechanical structure capable of preventing the used battery pack 3 from being mounted on the electric stapler in a mechanically connected manner.
Further, in the foregoing, how the plug 2 and the safety component 4 form a blocking or unblocking structure preferably adopts the following technical scheme:
in the present embodiment, referring to fig. 2, 3 and 4, the plug 2 is provided with a positioning lever 202, and the end surface of the positioning lever 202 facing the battery pack 3 is defined as a first limit surface 203;
the safety component 4 is provided with a safety block 401, the safety block 401 is arranged in the battery pack 3 in a telescopic way, and the telescopic direction of the safety block 401 is crossed with the first direction;
when the safety component 4 is in the initial state, the safety block 401 and the first limiting surface 203 are not interfered with each other;
when the safety assembly 4 is in the limit state, the first limit surface 203 is blocked by the safety block 401.
Wherein the length of the positioning rod 202 should satisfy the aforementioned second stroke; that is, the second stroke of the plug 2 inserted into the battery pack 3, specifically, the length of the positioning rod 202 inserted into the battery pack 3, if the length of the positioning rod 202 is smaller than the length of the second stroke, the contact between the plug 2 and the safety component 4 (specifically, the safety block 401) in the limit state can be affected, although the connection between the battery pack 3 and the plug 2 is not affected, and the contact between the first conductive sheet 201 of the plug 2 and the second conductive sheet 301 of the battery pack 3 is not affected;
that is, in the safety module 4 in the limit state, although the stroke of the positioning rod 202 inserted into the battery pack 3 can be blocked to be smaller than the second stroke, in this case, the first conductive sheet 201 and the second conductive sheet 301 may be caused to contact each other; therefore, the length of the positioning rod 202 should be slightly greater than or equal to the aforementioned length of the second stroke, so that the safety assembly 4 (specifically, the safety block 401) can prevent the stroke of the positioning rod 202 from satisfying the second stroke and avoid the mutual contact of the first conductive sheet 201 and the second conductive sheet 301.
Referring to fig. 2 or 3, the first limiting surface 203 of the positioning rod 202 is used for being contacted by the safety block 401; specifically, when the battery pack 3 is inserted by the plug 2 for the first time, along the first direction, the contour of the first limiting surface 203 may pass through the position of the safety component 4, so that the first limiting surface 203 and the safety block 401 are not contacted with each other, and the stroke of the first limiting surface 203 inserted into the battery pack 3 satisfies the second stroke; and, when the battery pack 3 is inserted by the plug 2 for the second time, along the first direction, the contour of the first limiting surface 203 contacts the contour of the safety block 401 in the safety assembly 4, and at this time, the stroke of the first limiting surface 203 inserted into the battery pack 3 cannot satisfy the second stroke.
The safety block 401 is configured as a telescopic connection structure with respect to the battery pack 3, wherein the telescopic direction of the safety block 401 is crossed with the first direction, and preferably, the telescopic direction of the safety block 401 is perpendicular to the first direction; if the first direction is considered to be longitudinal (see fig. 2 or 3), the telescoping direction of the safety block 401 may be considered to be transverse (see fig. 2 or 3) such that the two form a cross.
When the safety component 4 is in an initial state (see fig. 2), the safety block 401 is in a contracted state relative to the battery pack 3, so that the safety block 401 and the first limiting surface 203 are not interfered with each other; conversely, when the safety assembly 4 is in the limit state (see fig. 3), the safety block 401 is shifted from the contracted state to the released state with respect to the battery pack 3, so that the safety block 401 can be moved to a position interfering with the second stroke.
Therefore, in this embodiment, through the first limiting surface 203 of the positioning rod 202 on the plug 2 and the safety block 401 of the safety assembly 4 being mutually matched, when the safety assembly 4 is in the initial state, a non-blocking structure is formed between the first limiting surface 203 and the safety block 401, so as to realize how the plug 2 and the safety assembly 4 form a non-blocking structure, and when the safety assembly 4 is in the limiting state, a blocking structure is formed between the first limiting surface 203 and the safety block 401, so as to realize how the plug 2 and the safety assembly 4 form a blocking structure.
Further, in the foregoing, the plug 2 is used to control the safety assembly 4 to transition from the initial state to the limit state, so that the following technical solution is preferably adopted to avoid the interference between the movement path of the safety block 401 and the movement path of the positioning rod 202 of the plug 2.
In this embodiment, referring to fig. 2 or fig. 3, one side surface of the positioning rod 202 is a second limiting surface 204;
when the stroke of the plug 2 inserted into the battery pack 3 satisfies the first stroke, the plug 2 is configured to contact the safety assembly 4;
when the stroke of the plug 2 inserted into the battery pack 3 is greater than the first stroke and less than the second stroke, the safety block 401 is configured to contact the second limiting surface 204.
It should be appreciated that the time node of the contact action of the plug 2 with the safety assembly 4, the time node of the travel with the plug 2 satisfying the first travel and the time node satisfying the second travel, need to be determined in a specific logical relationship;
for convenience of explanation, a time node of the contact action of the plug 2 and the safety component 4 is defined as a first time node, a time node of the travel of the plug 2 satisfying the first travel is defined as a second time node, and a time node of the travel of the plug 2 satisfying the second travel is defined as a third time node;
assuming that the first time node precedes the second time node, in this case, it is explained that during the actual insertion of the plug 2 into the battery pack 3, the plug 2 first contacts the safety component 4, so that the safety component 4 starts to transition from the initial state to the limit state at the first time node, and at the same time, the first limit surface 203 of the plug 2 is actually inserted into the travel path of the battery pack 3 at the first time node, and the first travel path is not satisfied, which results in that, at the first time node, a distance is left between the first limit surface 203 and the end point of the first travel path, and this distance is easily occupied or inserted by the safety block 401' of the safety component 4 that is transitioning to the limit state, so that when the battery pack 3 is connected to the plug 2 for the first time, a phenomenon occurs in which the safety component 4 (the safety block 401) blocks the plug 2 (specifically, the positioning rod 202); therefore, the first time node cannot be configured before the second time node.
Therefore, in this embodiment, the first time node and the second time node are configured as the same time node, in this case, in the process of actually inserting the plug 2 into the battery pack 3, the first stroke is satisfied by the stroke of actually inserting the first limit surface 203 of the plug 2 into the battery pack 3 while the plug 2 contacts the safety component 4, and at this time, the safety component 4 is contacted by the plug 2, but the safety component 4 is not directly or immediately changed from the initial state to the limit state, so that the plug 2 can be continuously inserted into the battery pack 3; thereafter, in the process of the transition of the stroke of the plug 2 from the first stroke to the second stroke, the safety assembly 4 starts to transition from the initial state to the limit state, and in the process of the transition, the safety block 401 of the safety assembly 4 contacts the second limit surface 204 of the positioning rod 202, and the current safety block 401 cannot contact the first limit surface 203 because the current safety block 401 is actually located at the side of the second limit surface 204.
More specifically, referring to fig. 2 or 3, the safety assembly 4 further includes a safety cover 402 and a safety firing bar 403;
the safety cover plate 402 is fixedly or detachably arranged in the battery pack 3;
the safety trigger bar 403 and the safety block 401 are configured as telescopic pairs, and the safety trigger bar 403 and the safety block 401 respectively have a clamping position and a limiting position relative to the safety cover plate 402;
when the safety trigger bar 403 and the safety block 401 are respectively at the clamping positions relative to the safety cover plate 402, the safety assembly 4 is in an initial state;
when the safety trigger bar 403 and the safety block 401 are respectively located at the limiting positions relative to the safety cover plate 402, the safety assembly 4 is located at the limiting state.
The safety cover plate 402 is preferably connected to the inner wall of the battery pack 3 by adopting a detachable connection mode, specifically, a pair of positioning plates (not shown in the figure) are arranged on the inner wall of the battery pack 3, the pair of positioning plates are respectively provided with a clamping protrusion, meanwhile, the safety cover plate 402 is provided with a clamping groove, and the clamping protrusions of the pair of positioning plates are clamped in the clamping groove of the safety cover plate 402.
Referring to fig. 2 or 3, the stroke engagement state of the safety block 401 relative to the safety cover plate 402 is actually formed by connecting the safety trigger bar 403 with the safety block 401 and the safety cover plate 402 respectively; since the safety cover plate 402 is fixed relative to the battery pack 3, the safety block 401 in the engaged position is stationary relative to the battery pack 3, thereby forming that the safety assembly 4 is in the initial state as a whole;
when the safety trigger bar 403 is contacted by the plug 2, the safety trigger bar 403 only generates a movement which is separated from the safety cover plate 402, so that the safety trigger bar 403 can perform a movement in the direction of the safety block 401, however, the movement requires a certain time, and in this time, the safety trigger bar 403 is still in a clamping state, so that the safety block 401 is still stationary relative to the battery pack 3, and thus the safety block 401 cannot prevent the positioning bar 202 from moving continuously, that is, the safety block 401 cannot contact the first limiting surface 203;
after the safety trigger bar 403 is completely separated from the safety cover plate 402, the safety block 401 can move towards the direction of the positioning rod 202, but the positioning rod 202 at this time has continued to move a distance towards the direction meeting the second stroke, at this time, the safety block 401 starting to move can only contact the second limiting surface 204 but not the first limiting surface 203, and at the same time, the safety block 401 cannot continue to transition to the limiting state, that is, the current safety block 401 is in an intermediate position between the clamping position and the limiting position;
after the plug 2 and the battery pack 3 are separated from each other, the safety block 401 loses the blocking of the second limiting surface 204 of the positioning rod 202, so that the safety block 401 continues to move toward the limiting position until the safety block 401 stops moving, and the safety block 401 is in the limiting position.
More specifically, referring to fig. 9, 10 or 11, the safety cover 402 is provided with a chute 404, the chute 404 is in a through hole shape, and the extending direction of the chute 404 is intersected with the first direction;

the safety cover plate 402 is further provided with a clamping groove 405, and the clamping groove 405 is concaved in the safety cover plate 402 along the reverse direction of the first direction, wherein the sliding groove 404 is positioned between the head end and the tail end;
the safety trigger bar 403 penetrates through the sliding groove 404 along the reverse direction of the first direction, the safety trigger bar 403 is provided with a clamping protrusion 406, when the clamping protrusion 406 is arranged in the clamping groove 405, the safety trigger bar 403 and the safety block 401 are respectively located at clamping positions relative to the safety cover plate 402, and when the clamping protrusion 406 is separated from the clamping groove 405 and the safety trigger bar 403 moves to the tail end, the safety trigger bar 403 and the safety block 401 are respectively located at limiting positions relative to the safety bar part.
In this embodiment, the position of the safety block 401 is limited by actually using the position of the safety trigger bar 403 relative to the safety cover plate 402; when the safety trigger bar 403 is clamped on the safety cover plate 402, that is, the clamping protrusion 406 of the safety trigger bar 403 is clamped into the clamping groove 405 of the safety cover plate 402, the safety block 401 and the safety trigger bar 403 are limited together at the clamping positions, so that the whole safety assembly 4 is in an initial state; when the locking protrusion 406 of the safety trigger bar 403 is separated from the locking groove 405 of the safety cover plate 402, so that the safety trigger bar 403 and the safety block 401 respectively move towards the second limiting surface 204 of the positioning bar 202, the safety trigger bar 403 can be blocked by the safety cover plate 402 at the tail end after moving a certain distance, and the safety trigger bar 403 and the safety block 401 are respectively limited at the aforementioned limiting positions.

The purpose of setting the telescopic hole 407 of the safety block 401 is to provide a telescopic movable space for the safety firing bar 403; the safety trigger bar 403 receives the acting force of the plug 2, so that the safety trigger bar 403 moves along the first direction, and the safety trigger bar 403 moves into the telescopic hole 407 of the safety block 401.
A first spring 408 is arranged between the safety trigger bar 403 and the safety block 401, and the purpose of the first spring 408 is to limit the clamping of the safety trigger bar 403 in the clamping groove 405 of the safety cover plate 402 when the safety assembly 4 is in an initial state, so that the clamping protrusion 406 cannot be separated from the clamping groove 405 under the action of no external force; conversely, after the safety trigger bar 403 receives the force of the plug 2, the safety trigger bar 403 applies pressure to the first spring 408, so that the first spring 408 contracts, and the movement of the safety trigger bar 403 into the telescopic hole 407 of the safety block 401 is not affected.
More specifically, referring to fig. 2, 3 or 4, a second spring 409 is provided between the safety block 401 and the inner wall of the battery pack 3;
