[0003] In the prior art, the clamping device includes a base, a tooling and a bolt, and the bolt detachably connects the tooling to the base. When using this clamping device, it is necessary to first fix the battery in the tooling and then perform the printing operation. Since the sizes and shapes of different models of batteries are different, different toolings are used. When switching from one model of battery to another model of battery, it is necessary to change the model of the tooling. At this time, it is necessary to first unscrew the bolt, then replace it with another model of tooling, and finally use the bolt to fixedly connect the new tooling to the base.

[0004] The above-mentioned clamping device is cumbersome and inefficient in the process of changing the tooling, resulting in a reduction in the production efficiency of the batteries. Summary of the Utility Model

[0005] The purpose of the embodiments of the utility model is to provide a locking device and a clamping device, which can solve the problems of cumbersome operation and low efficiency of the clamping device in the prior art during the process of changing the tooling.

[0006] In order to solve the above technical problems, the utility model is implemented as follows:

[0007] In a first aspect, the embodiments of the utility model provide a locking device, which includes: a locking seat, a locking head, a plug pin and a buckle. The locking head is inserted into the locking seat, and the locking head can expand and contract relative to the locking seat along the insertion direction. The plug pin moves along its own axis direction and is engaged with or separated from the locking head. The axis of the plug pin intersects with the insertion direction of the locking head. A plug is provided at the first end of the plug pin, and a limiting protrusion is further provided on the plug pin. The limiting protrusion is spaced apart from the plug. The buckle is arranged on the plug pin and is located between the plug and the limiting protrusion, and the buckle moves between the limiting protrusion and the plug along the axis direction of the plug pin. Wherein, guiding structures are provided at the contact parts between the plug and the locking head and between the buckle and the locking head.

[0008] Optionally, along the opposite direction of the insertion direction of the plug pin, the locking head includes a first surface and a second surface;

[0009] Along the insertion direction of the bolt, the cross-section of the plug perpendicular to the insertion direction gradually decreases to form the guiding structure, and / or, along the retraction direction of the lock head, the cross-section of the lock head perpendicular to the retraction direction gradually increases and forms the guiding structure on the second surface.

[0010] Optionally, along the opposite direction of the insertion direction of the bolt, the lock head includes a first surface and a second surface;

[0011] Along the insertion direction of the bolt, the cross-section of the first end of the buckle perpendicular to the insertion direction gradually decreases to form the guiding structure, and / or, along the retraction direction of the lock head, the cross-section of the lock head perpendicular to the retraction direction gradually increases and forms the guiding structure on the second surface.

[0012] Optionally, along the opposite direction of the insertion direction of the bolt, the lock head includes a first surface and a second surface;

[0013] Along the insertion direction of the bolt, the cross-section of the second end of the buckle perpendicular to the insertion direction gradually increases to form the guiding structure, and / or, along the retraction direction of the lock head, the cross-section of the lock head perpendicular to the retraction direction gradually increases and forms the guiding structure on the first surface.

[0014] Optionally, the lock head includes a locking tongue and an elastic member. The elastic member is located within the lock seat, the locking tongue is inserted into the lock seat, along the telescopic direction, the first end of the elastic member is connected to the locking tongue, and the second end of the elastic member is connected to the lock seat.

[0015] Optionally, the lock seat is provided with a lock hole, the elastic member is located within the lock hole, and the lock head is inserted into the lock hole.

[0016] Optionally, the lock seat includes a first plug lock clamping block and a second plug lock clamping block. The first plug lock clamping block and the second plug lock clamping block are detachably connected. After the first plug lock clamping block and the second plug lock clamping block are connected, they form the lock seat and enclose to form the lock hole.

[0017] Optionally, the lock device further includes a bolt seat. The bolt seat is provided with a socket hole, the axis of the socket hole intersects with the insertion direction of the lock head, and the bolt is inserted into the socket hole.

[0018] Optionally, the bolt seat includes a first bolt clamping block and a second bolt clamping block. The first bolt clamping block and the second bolt clamping block are detachably connected. After the first bolt clamping block and the second bolt clamping block are connected, they form the bolt seat and enclose to form the socket hole.

[0019] Optionally, the latch device further includes a guiding ring sleeved on the bolt and clamped between the outer peripheral surface of the bolt and the inner wall of the socket, and the guiding ring is slidably connected to the bolt.

[0020] In a second aspect, an embodiment of the present invention further provides a clamping device, which includes a base, a fixing frame and the latch device according to any one of the first aspects above. The latch seat is fixedly connected to the base, and the bolt is connected to the fixing frame.

[0021] In the embodiment of the present application, since the buckle includes a first end and a second end, the first end of the buckle abuts against or separates from the plug, and the second end of the buckle abuts against or separates from the limiting protrusion. Such a structure forms the basic structure of the latch device. Since the bolt moves along its own axis and is clamped or separated from the lock head, the bolt can be connected or separated from the latch seat.

[0022] When using the latch device, first press the bolt downward. When the bolt is inserted, starting from the moment the plug touches the lock head, the lock head can be squeezed to retract under the action of the guiding structure at the contact part. When the lock head moves to the end away from the plug, the lock head will protrude again and then latch the lock head. At this time, the bolt is connected to the latch seat and the latch device is in the locked state.

[0023] When unlocking is required, press the bolt downward again. When the bolt continues to be inserted, starting from the moment the first end of the buckle touches the lock head, the lock head can be squeezed to retract under the action of the guiding structure. When the lock head moves along the first end of the buckle to the edge of the buckle, it can protrude again so that the lock head contacts the second end of the buckle. Finally, move the bolt in the opposite direction of the insertion direction from the second end of the bolt. At this time, the buckle abuts against the plug under the push of the lock head, and then the lock head is squeezed to retract to the edge of the buckle under the action of the guiding structure at the second end of the buckle, and then disengages from the buckle. At this time, the bolt disengages from the lock head, and then the bolt disengages from the latch seat, so that the latch device is in the unlocked state.

[0024] In summary, when using the latch device, only by pressing and pulling out the bolt can the locked state and the unlocked state of the latch device be achieved. This can simplify the locking and unlocking operations, and thus improve the locking and unlocking efficiency.

[0035] The following will combine with the attached drawings and through specific embodiments and their application scenarios, the buckle device 1 and the clamping device 100 provided by the embodiments of the present utility model will be described in detail.

[0036] Figure 1 is a schematic structural diagram of a buckle device 1 provided by the embodiments of the present utility model, Figure 2 is Figure 1 a schematic structural diagram when the lock head contacts the second end of the buckle.

[0037] Refer to Figure 1 and Figure 2 , the buckle device 1 includes: a buckle seat 11, a lock head 12, a bolt 13 and a buckle 14. The lock head 12 is inserted into the buckle seat 11, and the lock head 12 can be telescoped relative to the buckle seat 11 along the insertion direction ( Figure 1 the X direction in

[0038] In the embodiments of the present application, the buckle 14 includes a first end and a second end. The first end of the buckle 14 abuts against or separates from the plug 15, and the second end of the buckle 14 abuts against or separates from the limit protrusion 16. Such a basic structure of the buckle device 1 is formed. Since the bolt 13 moves along its own axis direction and is engaged with or separated from the lock head 12, the bolt 13 can be connected to or separated from the buckle seat 11.

[0039] When using the buckle device 1, first press the bolt 13 downward. When the bolt 13 is inserted, from the moment the plug 15 touches the lock head 12, the lock head 12 can be squeezed by the guiding structure at the contact part to make the lock head 12 retract. When the lock head 12 moves to the end away from the plug 15, the lock head 12 will extend again to catch the lock head 12. At this time, the bolt 13 is connected to the buckle seat 11, and the buckle device 1 is in a locked state.

[0040] When unlocking is required, press the bolt 13 downward again. In this way, when the bolt 13 continues to be inserted, starting from when the first end of the buckle 14 touches the lock head 12, the lock head 12 can be squeezed to retract under the action of the guiding structure. When the lock head 12 moves along the first end of the buckle 14 to the edge of the buckle 14, it can extend again so that the lock head 12 contacts the second end of the buckle 14. Finally, move the bolt 13 in the opposite direction of the insertion direction from the second end of the bolt 13. At this time, the buckle 14 abuts against the plug 15 under the push of the lock head 12. Then, under the action of the guiding structure at the second end of the buckle 14, the lock head 12 is squeezed to retract to the edge of the buckle 14, and then disengages from the buckle 14. At this time, the bolt 13 disengages from the lock head 12, and further disengages from the lock seat 11, so that the lock device 1 is in the unlocked state.

[0041] In summary, when using the lock device 1, only by pressing and pulling out the bolt 13 can the locked state and the unlocked state of the lock device 1 be achieved. This can simplify the locking and unlocking operations, and thus improve the efficiency of locking and unlocking.

[0042] Optionally, in some embodiments, refer to Figure 1 and Figure 2 , in the opposite direction of the insertion direction of the bolt 13 ( Figure 1 the Y direction in Figure 1 ), the lock head 12 includes a first surface 121 and a second surface 122; along the insertion direction of the bolt 13, the cross-section of the plug 15 perpendicular to the insertion direction gradually decreases to form a guiding structure, and / or, along the retracting direction of the lock head 12, the cross-section of the lock head 12 perpendicular to the retracting direction gradually increases and a guiding structure is formed on the second surface 122.

[0043] In the embodiment of the present application, since along the insertion direction of the bolt 13, the cross-section of the plug 15 perpendicular to the insertion direction gradually decreases to form a guiding structure. In this way, when the bolt 13 is inserted, starting from when the plug 15 touches the lock head 12, the lock head 12 can be squeezed to retract under the action of the guiding structure of the plug 15. When the lock head 12 moves to the end of leaving the plug 15, the lock head 12 will extend again to catch the lock head 12. At this time, the bolt 13 is connected to the lock seat 11, and thus the lock device 1 is in the locked state. And / or, along the retracting direction of the lock head 12 ( Figure 1 the X direction in Figure 1 ), the cross-section of the lock head 12 perpendicular to the retracting direction gradually increases and a guiding structure is formed on the second surface 122. In this way, when the bolt 13 is inserted, starting from when the plug 15 touches the lock head 12, the lock head 12 can be squeezed to retract under the action of the guiding structure on the second surface 122. When the lock head 12 moves to the end of leaving the plug 15, the lock head 12 will extend again to catch the lock head 12. At this time, it can also make the bolt 13 connected to the lock seat 11, and thus the lock device 1 is in the locked state.

[0044] It should be noted that the above two solutions may exist simultaneously or at least one of them may exist. The embodiments of the present application do not make any limitations in this regard.

[0045] Optionally, in some embodiments, referring to Figure 1 and Figure 2 , in the opposite direction of the insertion direction of the bolt 13, the lock head 12 includes a first surface 121 and a second surface 122; along the insertion direction of the bolt 13, the cross-section of the first end of the buckle 14 perpendicular to the insertion direction gradually decreases to form a guiding structure, and / or, along the retraction direction of the lock head 12, the cross-section of the lock head 12 perpendicular to the retraction direction gradually increases and forms a guiding structure on the second surface 122.

[0046] In the embodiments of the present application, since along the insertion direction of the bolt 13, the cross-section of the first end of the buckle 14 perpendicular to the insertion direction gradually decreases to form a guiding structure, when the bolt 13 continues to be inserted, the first end of the buckle 14 can squeeze the lock head 12 under the action of the guiding structure at the first end of the buckle 14 to retract the lock head 12 from the moment it touches the lock head 12, and when the lock head 12 moves along the first end of the buckle 14 to the edge of the buckle 14, it can extend again to make the lock head 12 contact with the second end of the buckle 14. And / or, along the retraction direction of the lock head 12, the cross-section of the lock head 12 perpendicular to the retraction direction gradually increases and forms a guiding structure on the second surface 122. In this way, when the bolt 13 continues to be inserted, when the first end of the buckle 14 touches the lock head 12, it can squeeze the lock head 12 under the action of the guiding structure on the second surface 122 of the lock head 12 to retract the lock head 12, and when the lock head 12 moves along the first end of the buckle 14 to the edge of the buckle 14, it can extend again to make the lock head 12 contact with the second end of the buckle 14.

[0047] It should be noted that the above two solutions may exist simultaneously or at least one of them may exist. The embodiments of the present application do not make any limitations in this regard.

[0048] Optionally, in some embodiments, referring to Figure 1 and Figure 2 , in the opposite direction of the insertion direction of the bolt 13, the lock head 12 includes a first surface 121 and a second surface 122; along the insertion direction of the bolt 13, the cross-section of the second end of the buckle 14 perpendicular to the insertion direction gradually increases to form a guiding structure, and / or, along the retraction direction of the lock head 12, the cross-section of the lock head 12 perpendicular to the retraction direction gradually increases and forms a guiding structure on the first surface 121.

[0049] In the embodiments of the present application, since the cross-section of the second end of the buckle 14 perpendicular to the insertion direction gradually increases along the insertion direction of the bolt 13 to form a guiding structure, when the bolt 13 moves along the pulling-out direction, first, the buckle 14 abuts against the plug 15 under the push of the lock head 12, and then under the action of the guiding structure at the second end of the buckle 14, the lock head 12 is squeezed so that the lock head 12 retracts to the edge of the buckle 14 and then disengages from the buckle 14. At this time, the bolt 13 disengages from the lock head 12, and further the bolt 13 disengages from the buckle seat 11, so that the buckle device 1 is in an unlocked state. And / or, along the retracting direction of the lock head 12, the cross-section of the lock head 12 perpendicular to the retracting direction gradually increases and a guiding structure is formed on the first surface 121. When the bolt 13 moves along the pulling-out direction, first, the buckle 14 abuts against the plug 15 under the push of the lock head 12, and then under the action of the guiding structure on the first surface 121 of the lock head 12, the lock head 12 is squeezed so that the lock head 12 retracts to the edge of the buckle 14 and then disengages from the buckle 14. At this time, the bolt 13 disengages from the lock head 12, and further the bolt 13 disengages from the buckle seat 11, so that the buckle device 1 can also be in an unlocked state.

[0050] It should be noted that the above two solutions can exist simultaneously or at least one of them can exist. The embodiments of the present application do not limit this.

[0051] It should also be noted that the guiding structures formed due to the gradual change of the cross-section above can be inclined surfaces, arc surfaces or spherical surfaces. The embodiments of the present application do not limit this.

[0052] See Figure 1 As shown in, a specific structure of a buckle device 1 is: along the insertion direction of the bolt 13, the cross-section of the plug 15 perpendicular to the insertion direction gradually decreases, and along the retracting direction of the lock head 12, the cross-section of the lock head 12 perpendicular to the retracting direction gradually increases and a guiding structure is formed on the second surface 122. Along the insertion direction of the bolt 13, the cross-section of the first end of the buckle 14 perpendicular to the insertion direction gradually decreases, and along the insertion direction of the bolt 13, the cross-section of the second end of the buckle 14 perpendicular to the insertion direction gradually increases.

[0053] When using the buckle device 1, first press the bolt 13 downward. When the bolt 13 is inserted, starting from touching the lock head 12, the plug 15 can squeeze the lock head 12 under the action of the guiding structure so that the lock head 12 retracts to the right. When the lock head 12 moves to leave the upper end of the plug 15, the lock head 12 will protrude to the left again and then lock the lock head 12. At this time, the bolt 13 is connected to the buckle seat 11 and the buckle device 1 is in a locked state.

[0054] When unlocking is required, press the bolt 13 downward again. In this way, when the bolt 13 continues to be inserted, starting from when the first end of the buckle 14 touches the lock head 12, the lock head 12 can be squeezed under the action of the guiding structure so that the lock head 12 retracts to the right. When the lock head 12 moves along the first end of the buckle 14 to the edge of the buckle 14, it can extend to the left again so that the lock head 12 contacts the second end of the buckle 14. Finally, move the bolt 13 in the opposite direction of the insertion direction from the second end of the bolt 13. At this time, the buckle 14 abuts against the plug 15 under the push of the lock head 12. Then, under the action of the guiding structure at the second end of the buckle 14, the lock head 12 is squeezed so that the lock head 12 retracts to the right to the edge of the buckle 14, and then disengages from the buckle 14. At this time, the bolt 13 disengages from the lock head 12, and further disengages from the lock seat 11, so that the lock device 1 is in the unlocked state.

[0055] Optionally, in some embodiments, refer to Figure 1 , Figure 2 and Figure 3 , the lock head 12 includes a lock tongue 123 and an elastic member 124. The elastic member 124 is located inside the lock seat 11. The lock tongue 123 is inserted into the lock seat 11. Along the telescopic direction, the first end of the elastic member 124 is connected to the lock tongue 123, and the second end of the elastic member 124 is connected to the lock seat 11.

[0056] In the embodiments of the present application, since the first end of the elastic member 124 is connected to the lock tongue 123 along the telescopic direction, and the second end of the elastic member 124 is connected to the lock seat 11. In this way, under the drive of the elastic member 124, the lock tongue 123 can be telescoped, and thus can cooperate to complete the locking process and unlocking process of the lock device 1. Then, since the elastic member 124 is located inside the lock seat 11 and the lock tongue 123 is inserted into the lock seat 11, the lock hole seat can limit the movement of the lock tongue 123 along the direction perpendicular to the retraction direction of the lock tongue 123, so that the lock device 1 can be made more stable.

[0057] It should be noted that the above elastic member 124 can be a rubber sleeve or a spring, or other elastic members 124 with the same function. The embodiments of the present application do not limit this.

[0058] Optionally, in some embodiments, refer to Figure 1 , Figure 2 and Figure 3 , the lock seat 11 is provided with a lock hole 111. The elastic member 124 is located inside the lock hole 111, and the lock head 12 is inserted into the lock hole 111. Specifically, the lock tongue 123 is inserted into the lock hole 111, so that the lock tongue 123 can only move along the axial direction of the lock hole 111. In this way, the lock hole 111 can limit the movement of the lock tongue 123 along a straight line direction, so that the lock device 1 can be made more stable.

[0059] It should be noted that the above latch hole 111 can be a round hole or a square hole, or a hole of other shapes, which depends on the shape of the locking tongue 123, and the embodiments of the present application do not limit this.

[0060] Optionally, in some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the latch seat 11 includes a first plug-in latch block 112 and a second plug-in latch block 113. The first plug-in latch block 112 and the second plug-in latch block 113 are detachably connected. After the first plug-in latch block 112 and the second plug-in latch block 113 are connected, they form the latch seat 11 and enclose to form the latch hole 111.

[0061] In this way, when connecting the locking tongue 123 with the latch seat 11, the locking tongue 123 and the elastic member 124 can be first connected with the first plug-in latch block 112, and then the second plug-in latch block 113 can be connected with the first plug-in latch block 112 so that the elastic member 124 is accommodated in the enclosed latch hole 111 and the locking tongue 123 is inserted into the latch hole 111. Compared with the solution of setting the latch seat 11 as an integral structure, this can make the assembly and connection of the latch device 1 more convenient.

[0062] It should be noted that the connection manner of the above first plug-in latch block 112 and the second plug-in latch block 113 can be snap 14 connection or bolt connection, or other connection manners, and the embodiments of the present application do not limit this.

[0063] Among them, the limiting protrusion 16 is an annular protrusion, and the annular protrusion extends along the circumferential direction of the plug pin 13. In this way, when the snap 14 moves to abut against the limiting protrusion 16, the force applied by the limiting protrusion 16 to the snap 14 can be made more uniform, so that the forces on each part of the second end of the snap 14 are relatively uniform, thereby improving the service life of the snap 14, and also improving the service life of the latch device 1.

[0064] It should be noted that the shape of the above annular protrusion can be a circular ring or a rectangular ring, or a ring of other shapes, which depends on the shape of the plug pin 13, and the embodiments of the present application do not limit this.

[0065] In addition, the snap 14 is annular, and the snap 14 is slidably connected with the plug pin 13. In this way, when the snap 14 moves to abut against the limiting protrusion 16, the forces on each part of the second end of the snap 14 can be made relatively uniform. When the snap 14 moves to abut against the plug 15, the forces on each part of the first end of the snap 14 can be made relatively uniform. That is, the forces received by the snap 14 at the first end and the second end can be made relatively uniform, thereby improving the service life of the snap 14, and further improving the service life of the latch device 1.

[0066] Subsequently, since the buckle 14 is slidably connected to the bolt 13, when the buckle 14 moves relative to the bolt 13, the frictional force between the buckle 14 and the bolt 13 can be reduced, thereby reducing the loss caused by friction between the buckle 14 and the bolt 13. Therefore, the service life of the buckle 14 and the bolt 13 can be extended, and the service life of the locking device 1 is also extended.

[0067] It should be noted that the above-mentioned ring can be a circular ring or a rectangular ring, or a ring of other shapes, which depends on the shape of the bolt 13, and the embodiments of the present application do not limit this.

[0068] It should also be noted that the above-mentioned sliding connection method between the buckle 14 and the bolt 13 can also be replaced by a rolling connection method, which can also reduce the loss caused by friction between the buckle 14 and the bolt 13. Therefore, the service life of the buckle 14 and the bolt 13 can also be extended.

[0069] Optionally, in some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , the locking device 1 further includes a bolt seat 17. The bolt seat 17 is provided with a jack 171. The axis of the jack 171 intersects with the insertion direction of the lock head 12, and the bolt 13 is inserted into the jack 171.

[0070] In this way, the jack 171 can limit the bolt 13 to move only along a direction perpendicular to the insertion direction of the lock head 12, and the moving direction of the jack 171 is on a straight line, that is, the jack 171 plays a guiding role when the bolt 13 moves, so that the bolt 13 can move along a specified direction.

[0071] It should be noted that the above-mentioned jack 171 can be a round hole or a square hole, or a hole of other shapes, which depends on the shape of the bolt 13, and the embodiments of the present application do not limit this.

[0072] Optionally, in some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , the bolt seat 17 includes a first bolt clamping block 172 and a second bolt clamping block 173. The first bolt clamping block 172 and the second bolt clamping block 173 are detachably connected. After the first bolt clamping block 172 and the second bolt clamping block 173 are connected, they form the bolt seat 17 and enclose to form the jack 171.

[0073] When connecting the bolt 13 to the bolt seat 17, the bolt 13 can be first connected to the first bolt clamping block 172, and then the second bolt clamping block 173 can be connected to the first bolt clamping block 172 so that the bolt 13 is inserted into the formed socket 171. Compared with the solution of setting the bolt seat 17 as an integral structure, the assembly and connection of the locking device 1 can be made more convenient.

[0074] It should be noted that the connection manner of the first bolt clamping block 172 and the second bolt clamping block 173 can be a snap 14 connection or a bolt connection, or other connection manners, which are not limited in the embodiments of the present application.

[0075] Optionally, in some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , the locking device 1 further includes a guide ring 18. The guide ring 18 is sleeved on the bolt 13 and clamped between the outer peripheral surface of the bolt 13 and the inner wall of the socket 171. The guide ring 18 is slidably connected to the bolt 13. The guide ring 18 can limit the movement of the bolt 13 along its own axis direction, so that the probability of insecure clamping caused by direction deviation during the clamping with the lock head 12 can be reduced. Furthermore, the probability of successful locking of the locking device 1 can be increased, that is, the failure rate of the locking device 1 is reduced.

[0076] In addition, since the guide ring 18 is slidably connected to the bolt 13. When the bolt 13 moves relative to the guide ring 18, the friction force between the guide ring 18 and the bolt 13 can be reduced, and further the loss caused by friction between the guide ring 18 and the bolt 13 can be reduced. Therefore, the service life of the guide ring 18 and the bolt 13 can be prolonged, and the service life of the locking device 1 is also prolonged.

[0077] It should be noted that the above guide ring 18 can be a circular ring or a rectangular ring, or a ring of other shapes, which depends on the shape of the bolt 13, and is not limited in the embodiments of the present application.

[0078] Referring to Figure 1 、 Figure 3 and Figure 4 , the embodiments of the present application also disclose a clamping device 100, which includes a base 2, a fixing frame 3 and any one of the above locking devices 1. The locking seat 11 is fixedly connected to the base 2, and the bolt 13 is connected to the fixing frame 3.

[0079] Since the locking device 1 can be locked and unlocked, the fixing frame 3 can be connected to or separated from the base 2 through the locking device 1. When the locking device 1 is in the locked state, the fixing frame 3 is connected to the base 2. When the locking device 1 is in the unlocked state, the fixing frame 3 is separated from the base 2.

[0080] When the latch device 1 includes a latch base 17, the latch seat 11 is fixedly connected to the base 2, and the latch base 17 is fixedly connected to the fixing frame 3.

[0081] When the clamping device 100 is applied to the production process of batteries in the related art, when switching from one type of battery to another type of battery and it is necessary to change the type of the fixing frame 3, only by pressing and pulling out the latch 13 can the connection or separation between the fixing frame 3 and the base 2 be achieved. This can improve the efficiency of replacing the fixing frame 3, and thus can improve the production efficiency of the batteries.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
