The assembly plate frame is rotatably connected to the connecting seat in the energy storage power supply body with the assistance of the shaft column, so that the assembly plate frame is set in a flippable structure on the energy storage power supply body. The connecting seat in the energy storage power supply body is tilted at its corner and is located on its diagonal line. By flipping the assembly plate frame, the position of the assembly plate frame on the adjacent two sides of the housing wall in the energy storage power supply body is exchanged. According to the parallel assembly requirements, the assembly plate frame is flipped and exchanged to the housing wall on the corresponding side of the energy storage power supply body for docking with the adjacent energy storage power supply body, realizing free adjustment and conversion of longitudinal stacking or transverse stacking, that is, meeting the purpose of different forms of combined assembly such as longitudinal stacking and parallel assembly or transverse stacking and parallel assembly, thereby increasing the scope of application and being suitable for placement and use requirements in different venues; Furthermore, the locking mechanism includes a first claw and a second claw, and the locking groove away from the flipping center of the assembly plate frame is adapted to the first claw and is arranged in a corresponding state, and the locking groove close to the flipping center of the assembly plate frame is adapted to the second claw and is arranged in a corresponding state.

In addition, the engagement between the limit groove and the positioning protrusion is coordinated to ensure the reliability of parallel assembly and avoid the phenomenon of slippage caused by left and right sliding displacement; 2. After the driving member drives the transmission rod to rotate synchronously, the meshing action between the second gear portion and the second rack portion drives the first linkage frame and the second linkage frame to slide in opposite directions. When the first linkage frame and the second linkage frame slide away from each other and outward, the meshing action between the first rack portion and the first gear portion causes the first clamping claw and the second clamping claw to be flipped and folded, and lose engagement with the two locking grooves respectively, thereby realizing a convenient unlocking operation. In addition, the first clamping claw and the second clamping claw are flipped and folded and stored in the groove cavity of the assembly plate frame, so that the energy storage power supply body and the assembly plate frame are combined to form a regular block body, which meets the purpose of separate pulling and disassembly. Different from the existing need to disassemble in sequence, it can realize interval disassembly operation, ensure the flexibility and convenience of disassembly, and facilitate later inspection and maintenance; Furthermore, when the first link frame and the second link frame slide inwardly toward each other, the first claw and the second claw are restricted by the pressure fit between the blocking portion and the corner block portion, and respectively maintain the engagement with the two locking grooves, thereby achieving reinforced locking after parallel assembly and improving the stability effect after parallel assembly.

The assembly plate frame 2 forms a flipping structure on the energy storage power supply body 1 with the assistance of the central axis column of the connecting seat, and its flipping can be used to exchange positions on the adjacent two side casing walls of the energy storage power supply body 1, and it cooperates with the locking mechanism 3 to operate the longitudinal stacking and parallel assembly or the transverse stacking and parallel assembly between the two adjacent energy storage power supply bodies 1.

[0023] Specifically, in this technical solution, when performing the flipping and replacement operation of the assembly plate frame 2 position, according to Figure 1 , Figure 3 and Figure 4As shown, a shaft column is rotatably connected to the connection seat in the energy storage power supply body 1, wherein the front and rear ends of the shaft column are respectively movably penetrated and inserted into the front and rear sides of the connection seat. Since an open groove is provided on the side of the assembly plate frame 2 close to the connection seat in the energy storage power supply body 1, the connection seat in the energy storage power supply body 1 is movably clamped in the groove after the assembly plate frame 2 is placed. Since the two ends of the shaft column of the connection seat in the energy storage power supply body 1 are respectively plugged in and fixedly connected to the groove walls on both sides of the groove in the assembly plate frame 2 by bolts, according to the parallel assembly requirements, with the assistance of the shaft column in the connection seat, the assembly plate frame 2 is turned over on the energy storage power supply body 1, and turned over and fitted to the casing wall on the corresponding side of the energy storage power supply body 1, so that the assembly plate frame 2 is set in a horizontal state on the casing wall on the corresponding side of the energy storage power supply body 1 after being turned over, and the position exchange of the assembly plate frame 2 is completed; Since a friction ring is installed at the rotation connection between the connection seat and the central axis column of the connection seat in the energy storage power supply body 1, the central axis column of the connection seat is prevented from rotating arbitrarily thereon through the friction damping effect, that is, the assembly plate frame 2 is prevented from turning over arbitrarily on the energy storage power supply body 1, and the initial limit is performed after the assembly plate frame 2 is turned over and replaced; Since the limiting grooves 4 are provided in the middle of the four sides of the upper, lower, left and right casing walls of the energy storage power supply body 1, the longitudinal section of the limiting grooves 4 is in a semicircular structure state, and since the middle of the assembling plate frame 2 is provided with a positioning protrusion 5 of an integrated structure, the positioning protrusion 5 is symmetrically arranged up and down with the horizontal center axis of the assembling plate frame 2, and its longitudinal section is also in a semicircular structure state, which is adapted to the limiting groove 4. When the assembling plate frame 2 is flipped and replaced, it fits with the casing wall on the corresponding side of the energy storage power supply body 1, so that the positioning protrusion 5 is engaged in the limiting groove 4. After the two are engaged, the assembling plate frame 2 is restricted to prevent the assembling plate frame 2 from sliding left and right after the assembling plate frame 2 is connected to the casing wall of the energy storage power supply body 1.

[0024] Specifically, in this technical solution, when the assembled plate frame 2 is flipped and replaced and locked by the locking mechanism 3, according to Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the locking mechanism 3 includes a first claw 6 away from the flipping center of the assembly plate frame 2 and a second claw 7 close to the flipping center of the assembly plate frame 2, and the first claw 6 and the second claw 7 are symmetrically arranged about the horizontal center axis of the assembly plate frame 2. Since locking grooves 9 are provided on the upper, lower, left and right four side casing walls of the energy storage power supply body 1, the locking grooves 9 are symmetrically arranged front to back about the horizontal center axis of the energy storage power supply body 1, respectively corresponding to the front and rear two locking mechanisms 3, and since the locking groove 9 away from the flipping center of the assembly plate frame 2 is adapted to the first claw 6 and arranged in a corresponding state, and the locking groove 9 close to the flipping center of the assembly plate frame 2 is adapted to the second claw 7 and arranged in a corresponding state, when the assembly plate frame 2 is flipped and replaced, the first claw 6 and the second claw 7 on one side of the assembly plate frame 2 are respectively connected to the two locking grooves 9 on the casing wall on the corresponding side of the energy storage power supply body 1; Since a groove cavity connected to the frame cavity is provided on the plate body of the assembled plate frame 2, the first claw 6 is arranged in an "L"-shaped structure, which is divided into a longitudinal claw body and a transverse claw body. The end of the longitudinal claw body in the first claw 6 is inserted and fixedly connected with a shaft column by bolts, wherein the front and rear ends of the shaft column respectively extend toward the front and rear outer sides of the first claw 6, and the two ends of the shaft column are respectively fixedly sleeved with bearings. After the first claw 6 is placed, it is arranged in a vertical state, wherein the longitudinal claw body is movably inserted in the groove cavity of the assembled plate frame 2, and the transverse claw body is placed outside the groove cavity, and the front and rear ends of the shaft column are respectively connected to the front and rear cavity walls of the groove cavity with bearings. Since the locking groove 9 is arranged in an "L"-shaped structure, which is divided into a longitudinal groove path and a transverse groove path, when the first claw 6 is docked with the locking groove 9 away from the flipping center of the assembled plate frame 2, the end of the transverse claw body in the first claw 6 is provided with an inclined side wall, and the first claw 6 is restricted. With the assistance of the inclined side wall, the first claw 6 is pushed on the assembled plate frame 2 to flip; Since spring magazines are provided on both the front and rear sides of the longitudinal claw body end of the first clamping claw 6, a torsion spring 8 for resetting is installed at the turning connection between the first clamping claw 6 and the assembled plate frame 2, and the torsion spring 8 is symmetrically arranged front and back. After the torsion spring 8 in the first clamping claw 6 is arranged, it is movably sleeved on the central axis of the first clamping claw 6 and placed in the spring magazine of the first clamping claw 6. One end of the torsion spring 8 is clamped on the spring magazine wall, and the other end is clamped on the cavity wall of the groove cavity in the assembled plate frame 2. After the first clamping claw 6 is pushed and flipped, the torsion spring 8 on it is elastically deformed by force. When the first clamping claw 6 is docked with the locking groove 9 away from the flipping center of the assembled plate frame 2, the first clamping claw 6 is not restricted, and the elastic deformation of the torsion spring 8 on it is used to reset, so that the first clamping claw 6 is reset and flipped on the assembled plate frame 2, and the first clamping claw 6 is automatically engaged and connected with the locking groove 9 away from the flipping center of the assembled plate frame 2, that is, the horizontal claw body in the first clamping claw 6 is hooked in the horizontal groove of the current locking groove 9; Since the second claw 7 and the first claw 6 have the same specifications, dimensions and structural shapes, and are also divided into a longitudinal claw body and a transverse claw body, the second claw 7 is placed on the assembly plate frame 2 in the same manner as the first claw 6 is placed on the assembly plate frame 2, and since a torsion spring 8 for resetting is installed at the flip connection between the second claw 7 and the assembly plate frame 2, the torsion spring 8 in the second claw 7 is placed in the same manner as the torsion spring 8 in the first claw 6. When the second claw 7 is docked with the locking groove 9 near the flip center of the assembly plate frame 2, an inclined side wall is provided at the end of the transverse claw body in the second claw 7. The claw 7 is restricted, and with the assistance of the inclined side wall, the second claw 7 is pushed and flipped on the assembly plate frame 2. After the second claw 7 is pushed and flipped, the torsion spring 8 on it is elastically deformed by force. When the second claw 7 is docked with the locking groove 9 near the flipping center of the assembly plate frame 2, the second claw 7 is not restricted, and the elastic deformation of the torsion spring 8 on it is used to reset, so that the second claw 7 is reset and flipped on the assembly plate frame 2, and the second claw 7 is automatically engaged and connected with the locking groove 9 near the flipping center of the assembly plate frame 2, that is, the horizontal claw body in the second claw 7 is hooked in the horizontal groove of the current locking groove 9; Since the flipping direction of the second claw 7 is opposite to the flipping direction of the first claw 6, and the two are arranged in opposite directions, through the cooperation between the first claw 6 and the second claw 7, and the engagement between the positioning protrusion 5 and the limit groove 4, the assembled panel frame 2 after flipping and replacement is automatically locked.

[0025] Specifically, in the technical solution, when the assembly frame 2 cooperates with the locking mechanism 3 to assemble two adjacent energy storage power supply bodies 1 in parallel, according to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, according to the above, since the first clamping claw 6 and the second clamping claw 7 are symmetrically arranged about the horizontal center axis of the assembly plate frame 2, locking grooves 9 are opened on the upper and lower left and right four side casing walls of the energy storage power supply body 1. The locking groove 9 away from the flipping center of the assembly plate frame 2 is adapted to the first clamping claw 6 and is arranged in a corresponding state, and the locking groove 9 close to the flipping center of the assembly plate frame 2 is adapted to the second clamping claw 7 and is arranged in a corresponding state. The two locking grooves 9 on the casing wall on the corresponding side of the adjacent energy storage power supply body 1 are respectively docked and engaged with the first clamping claw 6 and the second clamping claw 7 on the other side of the assembly plate frame 2 to complete the automatic locking of the two adjacent energy storage power supply bodies 1 after parallel assembly.

[0026] Embodiment 2: The present invention is based on the first embodiment. Figure 6-Figure 10The technical solution shown in the figure can be used to deal with the problem that when disassembling the energy storage power supply after parallel assembly, the existing disassembly method is limited by the connection method and can only be disassembled in sequence, and it is impossible to achieve separate disassembly at intervals, and the operation is not convenient enough. The linkage component 10 is symmetrically arranged front and back about the horizontal central axis of the assembly plate frame 2, corresponding to the front and rear two locking mechanisms 3 respectively. The locking mechanism 3 is flipped and folded on the assembly plate frame 2 by operating the linkage component 10, and folded and stored in the groove cavity of the assembly plate frame 2. After the locking effect of the locking mechanism 3 is released, the energy storage power supply body 1 and the assembly plate frame 2 are combined to form a regular block body, which can be pulled out and disassembled individually, and meets the purpose of interval disassembly.

[0027] Specifically, in the technical solution, a driving assembly 16 for operating the sliding of the first linkage frame 11 and the second linkage frame 12 is provided at the joint of the first linkage frame 11 and the second linkage frame 12. The driving assembly 16 is placed in the middle of the frame cavity of the assembly plate frame 2 and is used for synchronously driving the front and rear linkage assemblies 10. When the driving assembly 16 drives the linkage assembly 10, according to Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a groove cavity is opened in the middle of the front side wall of the assembly plate frame 2, and the cross section of the driving member 20 is arranged in a "convex"-shaped structure, which is divided into two parts, a wide part and a narrow part. After the driving member 20 is placed, the wide part is movably clamped in the groove cavity of the middle front side wall of the assembly plate frame 2, and the narrow part movably penetrates through the front side wall of the assembly plate frame 2 and extends outward, and the front end of the narrow part is clamped and fixedly connected with a turning handle by bolts, and the turning handle of the driving member 20 is manually screwed to make the driving member 20 rotate on the front side wall of the assembly plate frame 2; Since the front and rear sections of the rod body in the transmission rod 19 are fixedly connected with bearings, after it is installed, the bearing is movably inserted in the middle part of the assembly plate frame 2, and its front end rod body movably penetrates the middle part of the spline column 28 and extends forward to the groove cavity of the front side wall in the assembly plate frame 2. Since the front end rod body of the transmission rod 19 is arranged in a square rod-shaped structure, a square tube groove is opened at the center position of the narrow part of the driving member 20, wherein the square tube groove is adapted to the square rod end of the transmission rod 19. Since the driving member 20 is arranged on the same central axis with the transmission rod 19, the square rod end of the transmission rod 19 is movably inserted and clamped in the square tube groove of the driving member 20. After the driving member 20 is driven to rotate, the driving rod 19 and the driving member 20 form a synchronous rotation structure through the clamping action between the square rod end in the transmission rod 19 and the square tube groove in the driving member 20, and the transmission rod 19 is rotated in the middle part of the assembly plate frame 2; Since the first annular groove 25 is provided in the groove cavity of the front side wall of the assembly plate frame 2, wherein the longitudinal section of the groove cavity is a semicircular arc structure, which is adapted to the hemispherical end of the positioning pin 23, and it is arranged concentrically with the driving member 20, and since the positioning pin 23 is provided at the connection between the driving member 20 and the energy storage power supply body 1, the positioning pin 23 is symmetrically arranged about the central axis of the wide part of the driving member 20, and wherein the hemispherical end is connected to the first annular groove 25 by snapping, the driving member 20 is movably positioned through the snapping action between the positioning pin 23 and the first annular groove 25, so that the spline groove 27 in the driving member 20 does not contact the spline column 28, and when the driving member 20 is driven to rotate, the positioning pin 23 slides along the first annular groove 25, and does not affect the rotation of the driving member 20; Since the front and rear sections of the transmission rod 19 are both provided with an integrated second gear portion 21, the front and rear second gear portions 21 correspond to the front and rear linkage components 10 respectively, the second gear portion 21 is placed at the joint between the inner end of the first linkage frame 11 and the inner end of the second linkage frame 12, and is placed in the middle position of the second rack portion 22. Since one end of the first linkage frame 11 close to the second linkage frame 12 is the inner end, and the other end is the outer end, the second linkage frame 12 and the first linkage frame 11 have the same structural shape and specification size, and are also divided into an inner end and an outer end. The second rack portion 22 is an integrated structure and is arranged at the first linkage frame 11. The inner end of a linkage frame 11 is meshed with the upper side of the second gear portion 21, and the second rack portion 22 is arranged at the inner end of the second linkage frame 12 in an integrated structure, and is meshed with the lower side of the second gear portion 21. Since the inner end of the first linkage frame 11 is bent, the inner end of the first linkage frame 11 and the inner end of the second linkage frame 12 are connected to each other in an up-and-down offset state. After the transmission rod 19 is driven to rotate, the second gear portion 21 and the transmission rod 19 constitute a synchronous rotation structure, and the meshing action between the second gear portion 21 and the second rack portion 22 drives the first linkage frame 11 and the second linkage frame 12 to slide in opposite directions.

[0028] Specifically, in the technical solution, the linkage assembly 10 includes a first linkage frame 11 for driving the first claw 6 alone and a second linkage frame 12 for driving the second claw 7 alone. When the locking mechanism 3 is flipped and folded by the linkage assembly 10 in the frame cavity of the assembled plate frame 2, according to Figure 6 and Figure 8As shown, since the first linkage frame 11 is arranged in an active state and is stuck in the frame cavity of the assembly plate frame 2 after being arranged, the arrangement method of the second linkage frame 12 on the assembly plate frame 2 is the same as the arrangement method of the first linkage frame 11 on the assembly plate frame 2, and since a spring compartment is provided at the outward end of the first linkage frame 11, a return spring member 13 is installed at the sliding connection between the first linkage frame 11 and the assembly plate frame 2 and the sliding connection between the second linkage frame 12 and the assembly plate frame 2. Both ends of the return spring member 13 are provided with end blocks of an integrated structure, which are arranged symmetrically front and back. The movable plug is arranged in the spring bin of the first linkage frame 11, and one end block thereof is fixedly connected to the spring bin wall by bolts, and the other end block thereof is fixedly connected to the frame cavity wall of the assembly plate frame 2 by bolts. The arrangement mode of the return spring member 13 in the second linkage frame 12 is the same as the arrangement mode of the return spring member 13 in the first linkage frame 11. The first linkage frame 11 and the second linkage frame 12 are driven to slide in opposite directions in the frame cavity of the assembly plate frame 2, that is, the two slide away from each other and outward, so that the return spring member 13 in the first linkage frame 11 and the return spring member 13 in the second linkage frame 12 are squeezed and elastically deformed; Since the first linkage frame 11 is arranged between the upper and lower first claws 6, a first rack portion 14 of an integrated structure is provided in the middle of the frame body of the first linkage frame 11, wherein the first rack portion 14 is symmetrically arranged about its horizontal central axis, corresponding to the upper and lower first claws 6 respectively, and since a first gear portion 17 of an integrated structure is provided at the middle position of the end of the longitudinal claw body in the first claw 6, the center of which coincides with the flipping center of the first claw 6, and since the specifications and dimensions of the tooth block in the first rack portion 14 are the same as those of the tooth block in the second rack portion 22, when the first linkage frame 11 slides outward, the first rack portion 14 thereon is connected with the first gear portion 17 in the first claw 6 in a meshing manner, and through the meshing action of the two, the first claw 6 is flipped and folded, and the first claw 6 is flipped and folded and stored in the groove cavity of the assembly plate frame 2; Since the second linkage frame 12 is placed between the upper and lower second claws 7, a first rack portion 14 of an integrated structure is provided in the middle of the frame body of the second linkage frame 12, wherein the first rack portion 14 is symmetrically arranged about its horizontal central axis, corresponding to the upper and lower second claws 7 respectively, and since a first gear portion 17 of an integrated structure is provided at the middle position of the end of the longitudinal claw body in the second claw 7, the arrangement method of the first gear portion 17 in the second claw 7 is the same as the arrangement method of the first gear portion 17 in the first claw 6, when the second linkage frame 12 slides outward, the first rack portion 14 thereon is connected with the first gear portion 17 in the second claw 7 in a meshing manner, and through the meshing action of the two, the second claw 7 is flipped and folded, and the second claw 7 is flipped and folded and stored in the groove cavity of the assembly plate frame 2; Since the longitudinal groove in the locking groove 9 is arranged in an arc-shaped structure, the locking groove 9 away from the flipping center of the assembly plate frame 2 corresponds to the first claw 6, wherein the arc center of the longitudinal groove coincides with the flipping center of the first claw 6, and does not affect the flipping and folding of the first claw 6; the locking groove 9 close to the flipping center of the assembly plate frame 2 corresponds to the second claw 7, wherein the arc center of the longitudinal groove coincides with the flipping center of the second claw 7, and does not affect the flipping and folding of the second claw 7; Since the distance between the two corner blocks 18 is greater than the width of the first rack portion 14, the first rack portion 14 is not blocked by the corner blocks 18 when meshing with the first gear portion 17, and the first rack portion 14 will not affect the flipping motion of the corner blocks 18. In addition, the first linkage frame 11 is set in an active positioning state with the assistance of the return spring member 13, and the second linkage frame 12 is set in an active positioning state with the assistance of the return spring member 13. A gap is reserved between the first rack portion 14 and the blocking portion 15. In the initial state, the first claw 6 or the second claw 7 is placed in the gap between the two, which does not affect the flipping movement of the first claw 6 or the second claw 7.

[0029] Specifically, in this technical solution, when performing a separate disassembly operation of the energy storage power supply body 1, according to Figure 6 and Figure 8 As shown, according to the above, after the first claw 6 and the second claw 7 are flipped and folded, the engagement and locking between the two locking grooves 9 are released, that is, the lock between the energy storage power supply body 1 and the assembly plate frame 2 is released. Since a flippable handle is movably arranged on the front shell of the energy storage power supply body 1, the energy storage power supply body 1 is pulled by the handle. Since the front and rear ends of the limiting groove 4 are both set in an open state, after the energy storage power supply body 1 is pulled, the positioning protrusion 5 can slide out through the open part at the end of the limiting groove 4, and the separate disassembly operation of the energy storage power supply body 1 is completed.

[0030] Specifically, in the technical solution, when the locking mechanism 3 is blocked and limited by the linkage assembly 10 in the frame cavity of the assembled plate frame 2, according to Figure 6 and Figure 7 As shown, according to the above, manually reversely twist the handle of the driving member 20, so that the driving member 20 rotates in the opposite direction at the front side wall of the assembly plate frame 2, and the transmission rod 19 rotates in the opposite direction synchronously at the middle part of the assembly plate frame 2, and the first linkage frame 11 and the second linkage frame 12 are driven to slide in opposite directions through the meshing action between the second gear portion 21 and the second rack portion 22, that is, the two are close to each other and slide inward, so that the return spring member 13 in the first linkage frame 11 and the return spring member 13 in the second linkage frame 12 are pulled and elastically deformed; Since the first linkage frame 11 is placed between the upper and lower first claws 6 after being installed, the first linkage frame 11 is provided with a blocking portion 15 of an integrated structure protruding outwardly, wherein the blocking portion 15 is symmetrically arranged about its horizontal central axis, corresponding to the upper and lower first claws 6 respectively, and since the front and rear positions of the ends of the longitudinal claw bodies in the first claws 6 are provided with corner blocks 18 of an integrated structure, after the corner blocks 18 in the first claws 6 are installed, they are in a vertical state with the longitudinal claw bodies in the first claws 6, so that the lower side walls thereof are arranged in a parallel state with the blocking portion 15, and when the first linkage frame 11 slides inwardly, the upper blocking portion 15 and the corner blocks 18 in the first claws 6 are connected by a pressing manner, and through the pressing cooperation between the two, the first claw 6 is blocked and limited, and the first claw 6 engaged in the locking groove 9 is further locked; Since the second linkage frame 12 is arranged between the upper and lower second claws 7, the blocking portion 15 of the second linkage frame 12 protrudes outward and is provided with an integrated structure. The blocking portion 15 in the second linkage frame 12 is symmetrically arranged about its horizontal center axis, corresponding to the upper and lower second claws 7 respectively. Moreover, since the front and rear positions of the ends of the longitudinal claw bodies in the second claws 7 are provided with an integrated structure of the corner block portion 18, the arrangement mode of the corner block portion 18 in the first claw 6 is the same as the arrangement mode of the corner block portion 18 in the second claw 7. When the second linkage frame 12 slides inward, the blocking portion 15 thereon is connected with the corner block portion 18 in the second claw 7 by abutting and pressing. Through the abutting and pressing cooperation between the two, the second claw 7 is blocked and limited, and the second claw 7 engaged in the locking groove 9 is further locked. Since the cross-section of the blocking portion 15 is in a "U"-shaped structure, the width of the first gear portion 17 is smaller than the width of the "U"-shaped frame cavity in the blocking portion 15. When the corner block portion 18 is pressed against the blocking portion 15, the first gear portion 17 is placed in the "U"-shaped frame cavity of the blocking portion 15 and will not cause obstruction.

[0031] Specifically, in the technical solution, when the sliding first linkage frame 11 and the second linkage frame 12 are locked, according to Figure 7 , Figure 8 and Fig.10As shown, a second annular groove 26 is provided at the rear of the first annular groove 25 and is opened in the groove cavity of the front side wall of the assembly plate frame 2. The specifications, dimensions and structural shapes of the two are the same. The second annular groove 26 is arranged concentrically with the driving member 20. Since the positioning pin 23 is arranged in a nail-shaped structure, after it is installed, the nail tail part is movably inserted into the cavity wall of the wide part of the driving member 20, and the nail head part thereof is movably inserted through the cavity wall to extend outward. The nail head part of the positioning pin 23 is arranged in a hemispherical structure. Since a positioning spring 24 is installed at the sliding connection between the positioning pin 23 and the driving member 20, the positioning spring 24 is placed in the cavity wall of the wide part of the driving member 20 after installation, one end of the positioning spring presses against the cavity wall, and the other end presses against the nail tail part of the positioning pin 23. The spacing dimension between the first and second annular grooves 26 is equal to the maximum sliding distance dimension of the driving member 20. After manually screwing the driving member 20 to drive the first linkage frame 11 and the second linkage frame 12 to slide, the driving member 20 is pressed to make the driving member 20 slide on the square rod end of the transmission rod 19. When the driving member 20 slides, the hemispherical end of the positioning pin 23 loses engagement with the first annular groove 25, so that the positioning pin 23 shrinks and slides on the wide part of the driving member 20, and the positioning spring 24 is squeezed and elastically deformed. After the driving member 20 slides, the positioning spring 24 is reset by elastic deformation, so that the positioning pin 23 extends and slides on the wide part of the driving member 20, and the hemispherical end of the positioning pin 23 is engaged and connected with the second annular groove 26, so that the sliding driving member 20 is positioned; Since the spline column 28 is fixed in the groove cavity of the front side wall of the assembly plate frame 2, a spline groove 27 concentric with the driving member 20 is opened in the wide portion thereof, and the spline groove 27 and the spline column 28 are on the same central axis and are arranged correspondingly. Since the number of tooth blocks of the spline column 28 is equal to the number of tooth blocks of the second gear portion 21, the thickness of the spline column 28 is smaller than the maximum sliding distance of the driving member 20. When the driving member 20 slides, the spline column 28 and the spline groove 27 are connected in a snap-fitting manner, so that the spline column 28 limits and locks the driving member 20, and indirectly locks the first linkage frame 11 and the second linkage frame 12 after sliding through the meshing action between the second gear portion 21 and the second rack portion 22, and through the snap-fit ​​action between the transmission rod 19 and the driving member 20.
