Description

Technical Field

[0001] This invention relates to the field of electric forklift technology, specifically to a multi-functional electric forklift and its usage method. Background Technology

[0002] The electric forklift head is powered by an assembled battery to control the forklift to transport goods. With the help of a removable battery and assembled protective devices, the stability and safety of the electric forklift can be improved. It can also effectively save energy and reduce emissions while preventing the impact on the service life of the electric forklift. However, there are still some problems with the use of existing electric forklifts.

[0003] In the prior art, the patent publication (announcement) number CN116692726A describes a "multi-functional electric forklift" which includes a support frame. A U-shaped support frame is slidably connected inside the support frame. The upper surface of the U-shaped support frame has equally spaced toothed grooves. Four adjusting push blocks are fixedly connected to the upper surface of the U-shaped support frame. The support frame has a motor slot, two cavity slots, and two placement slots inside.

[0004] During the operation of the above-mentioned device, by setting up components such as Gear 1, Gear 2, and drive shaft, the drive shaft can drive Gear 2 through the mutual cooperation between Gear 1 and Gear 2. This achieves the effect that the device can simultaneously drive two Gear 1s through Gear 2, and realize the forward and backward movement of the U-shaped support frame by switching between the two Gear 1s. This prevents the U-shaped support frame from being pulled and jammed due to uneven force caused by manual pulling. However, in use, it is inconvenient to control the spacing of the forks according to the size of the pallet, which requires manual adjustment. After adjustment, it is easy to cause center offset, affecting the stability of the electric forklift. Furthermore, it is inconvenient to assemble different forks to meet the needs of different transported goods.

[0005] In the prior art, the patent publication (announcement) number CN208022648U, entitled "A Multifunctional Electric Forklift," includes a mounting housing containing a battery. A mounting plate is mounted on the top of the housing via a support column. A solar panel is embedded in the top of the mounting plate. A light is mounted on the top of one end of the mounting plate. A camera is mounted on the surface of the mounting plate next to the light. A health indicator and a hazard indicator are mounted on the surface of the control box below the display screen. Pressure sensors are embedded in the surface of the forks. The inclusion of a solar panel, light, camera, display screen, health indicator, hazard indicator, and pressure sensors solves the problems of maximizing cargo handling efficiency, improving work efficiency, and achieving diverse functions in the electric forklift during cargo transportation.

[0006] In the prior art, the patent publication (announcement) number CN219058459U, entitled "A Multifunctional Fork for an Automated Electric Forklift", includes two uprights. Forks are fixedly connected to the lower end of one side of each of the two uprights. Two mounting holes are opened on the upper end of each of the two forks. A first hydraulic telescopic rod is fixedly connected to one side of the upper end of each of the two forks. A pressure plate is fixedly connected to the upper end of each of the two first hydraulic telescopic rods. A locking block is fixedly connected to both ends of the side of each upright away from the forks. A locking groove is opened inside each of the locking blocks. A connecting plate is slidably connected to the inner wall of each of the two locking grooves. A second hydraulic telescopic rod is fixedly connected to the middle of one side of the connecting plate.

[0007] During the operation of the above-mentioned device, the fork mechanism adds a mechanism for fixing the goods and a mechanism for unloading the goods compared to the original fork mechanism. In actual use, it greatly improves its practical performance and reduces the labor intensity of manual labor. However, the forks have limitations when in use. When transporting goods that need to be flipped, it is not convenient to form an upper and lower clamp to assist in the transfer of goods. In addition, when transporting some relatively loose goods, the goods are very likely to slip off from above. Summary of the Invention

[0008] The purpose of this invention is to provide a multi-functional electric forklift and its usage method, to solve the problems mentioned in the background art, such as the inconvenience of controlling the spacing of the forks according to the size of the cargo pallet, the need for manual adjustment, the tendency for center offset after adjustment to affect the stability of the electric forklift, the inconvenience of assembling different forks to meet the needs of different cargo transport, the limitations of the forks during use, the inconvenience of forming upper and lower clamps to assist in cargo transfer when transporting goods that need to be flipped, and the problem that cargo is prone to slipping off the top when transporting some loose cargo.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional electric forklift and its method of use, comprising an electric forklift body that operates electrically, wherein a first telescopic frame is installed on the left side of the outer surface of the electric forklift body, and an inclined hydraulic cylinder is connected to the lower right section of the outer surface of the first telescopic frame, a second telescopic frame is telescopically connected to the middle section of the inner surface of the first telescopic frame, and a fixed seat is telescopically connected to the inner surface of the second telescopic frame.

[0010] Includes: a fixing plate, installed on the outer surface of the fixing base, and a small gear is rotatably connected to the right side of the outer surface of the fixing plate, and a large gear is meshed with the outer surface of the small gear. Meanwhile, a main shaft is installed at the central axis of the inner surface of the large gear, and a retaining rack is installed on the outer surface of the main shaft.

[0011] A slider is installed on the right side of the outer surface of the barrier, and a groove opened in the fixing plate is slidably connected to the outer surface of the slider. A spur gear is rotatably connected to the inner surface of the barrier, and a rack is meshed on the outer surface of the spur gear. A moving rod is installed on the outer surface of the rack.

[0012] A limiting rod is installed on the outer surface of the movable rod, and the limiting rod slides on the side between the limiting plates installed on the barrier shelf. A limiting groove is opened on the inner surface of the limiting plate. Meanwhile, a disassembly assembly is installed on the outer surface of the movable rod, and the disassembly assembly slides in the limiting groove at the connection between the disassembly assembly and the movable rod.

[0013] A support member is installed on the outer surface of the disassembly assembly, and a positioning member is installed on the lower side of the outer surface of the disassembly assembly. The main forks are assembled on the outer surfaces of the support member and the positioning member.

[0014] A lateral hydraulic cylinder is installed on the outer side of the rack, and a hydraulic rod is telescopically connected to the inner surface of the lateral hydraulic cylinder. A positioning groove is opened on the outer surface of the hydraulic rod, an auxiliary fork is installed on the upper surface of the hydraulic rod, and a rotating seat is slidably connected to the upper side of the outer surface of the hydraulic rod.

[0015] Preferably, the fixed seat and the fixed plate form an integrated structure, and the fixed plate forms a meshing structure with a small gear and a large gear, and the large gear forms a rotating structure with the barrier shelf through a main shaft. At the same time, the barrier shelf forms a nested sliding structure with the fixed plate through a slider and a slide groove, and the slider is set at an angle to the central axis of the outer surface of the barrier shelf.

[0016] The above structure facilitates stable meshing adjustment during use, thereby controlling the stability of the barrier rack rotation through multi-tooth ratio control, and the setting of sliders and grooves prevents the barrier rack from falling off.

[0017] Preferably, the baffle rack is meshed with a spur gear and a rack, and the rack is integrated with a moving rod and a limiting rod. The moving rod is limited and slidable with a limiting plate through a limiting rod. The moving rod is embedded in the outer surface of the assembly and disassembly component. The outer surface of the moving rod is bent, and the connection between the moving rod and the assembly and disassembly component is slidable with a limiting groove and a limiting plate.

[0018] With the above structure, it is easy to effectively control the relative adjustment of the moving rod during use, thereby controlling the limited movement of the disassembly and assembly components and adjusting the stability of the movement of the main forks on the disassembly and assembly components.

[0019] Preferably, the inner surface of the disassembly assembly is rotatably connected to a turntable, and the outer surface of the turntable is rotatably connected to a connecting rod. The other end of the outer surface of the connecting rod is rotatably connected to a locking block. Meanwhile, a limit block is installed on the outer surface of the locking block and is slidably connected to the inner surface of the disassembly assembly. At the same time, the outer surface of the limit block is limited and connected to the main fork.

[0020] The above structure allows for stable assembly during use, thereby controlling the position of the locking block and adjusting the locking block to engage and position the replaceable main forks.

[0021] Preferably, the turntable and the disassembly / assembly assembly form a rotating structure, and the disassembly / assembly assembly forms a circumferential linear movement structure with the locking block through the turntable, connecting rod 1, and limiting block. The locking block is symmetrically arranged about the middle section of the inner surface of the disassembly / assembly assembly, and the outer surface of the locking block has an "L" shaped structure. The locking block and the main fork form a limiting engagement structure.

[0022] The above structure facilitates effective rotational linkage adjustment during use, thereby controlling the synchronous movement of the locking blocks and enabling the locking blocks to perform secondary locking and fixing of the main forks.

[0023] Preferably, the support member, the disassembly assembly, and the positioning member form an integrated structure, and the disassembly assembly forms a limiting support structure with the main fork through the support member and the positioning member, and the outer surface of the support member has an "L" shaped structure.

[0024] The above structure effectively engages and positions the main forks during use, and provides support to their bottom, preventing the main forks from wobbling during the operation of the electric forklift.

[0025] Preferably, the lateral hydraulic cylinder is embedded in the outer surface of the shelf, and the lateral hydraulic cylinder forms a limiting telescopic structure with the auxiliary fork through the hydraulic rod, and the hydraulic rod forms a nested installation structure with the auxiliary fork through the positioning groove, while the rotating seat and the hydraulic rod form a sliding limiting structure.

[0026] The above structure facilitates effective control of the extension and retraction of the auxiliary forks during use, and ensures stability during use to prevent them from falling off.

[0027] Preferably, a nested ring is rotatably connected to the lower side of the outer surface of the rotating seat, and the nested ring is installed on the upper side of the outer surface of the lateral hydraulic cylinder. A connecting rod two is rotatably connected to the outer surface of the rotating seat, and a telescopic rod is rotatably connected to the other side of the outer surface of the connecting rod two. At the same time, a telescopic assembly is telescopically connected to the outer surface of the telescopic rod, and a support seat is installed on the outer surface of the telescopic assembly.

[0028] The above structure allows for stable assembly during use, and, in conjunction with the telescopic structure, it allows for adjustment of the swivel seat angle and control of the auxiliary fork angle.

[0029] Preferably, the nested ring and the rotating seat form a limiting rotation structure, and the nested ring forms a telescopic rotation structure with the telescopic assembly through the second connecting rod and the telescopic rod. The outer surface of the second connecting rod has a bent shape, and the outer surface height of the telescopic assembly is lower than the outer surface height of the support seat.

[0030] The above structure allows for effective synchronous control of the angles of the auxiliary forks on both sides during use, improving operational stability.

[0031] Preferably, the method of using the multi-functional electric forklift includes the following steps:

[0032] S1: Start the electric forklift body for the goods to be transferred, adjust the angle between the first telescopic frame and the electric forklift body through the assembled inclined hydraulic cylinder, and adjust the height of the rack assembled on the fixed plate mounted on the fixed seat through the extension and retraction of the second telescopic frame, and cooperate with the main forks on the rack to support the goods to be transferred.

[0033] S2: When using the backrest rack, the spur gear of the assembled motor can be adjusted to control the moving rod mounted on the rack, and the limiting rod mounted on the moving rod can form a limiting slide between the limiting plate and the backrest rack, thereby controlling the sliding of the disassembly and assembly components mounted on the moving rod in the limiting groove, which in turn controls the spacing of the main forks assembled from the disassembly and assembly components and can improve the stability of the main forks when they move.

[0034] S3: When different main forks are required, the support component assembled by the disassembly and assembly components forms an upper locking support for the main forks, and forms a rotational locking during assembly. When the main forks are vertically assembled after locking, the lower part of the main forks is nested on the outer surface of the positioning component to form a bottom support. The motor of the disassembly and assembly components is controlled, and the output shaft controls the rotation of the turntable connected to the first linkage. The rotating adjustment block and the limit block slide on the inner surface of the disassembly and assembly components to control the block to fix the main forks for a second time.

[0035] S4: When moving goods that need to be flipped, the assembled main forks can provide support, and the lateral hydraulic cylinder can be activated to control the hydraulic rod-mounted auxiliary forks to move upward. This activates the telescopic assembly, which drives the telescopic rod to retract and rotate the second adjusting linkage. This, in turn, drives the rotating seat connected to the nested ring positioning rotation, which, in conjunction with the positioning groove, controls the hydraulic rod to rotate and adjust. This also controls the auxiliary forks to move downward and clamp the upper side of the goods. The motor on the fixed plate is activated, which controls the small gear and large gear to mesh and adjust the stop rack mounted on the main shaft to rotate. This controls the flipping between the main forks and auxiliary forks, flipping the goods. When it is not necessary to flip the goods, the auxiliary forks can also be used to position and clamp the upper end of the goods.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. This multi-functional electric forklift and its usage method are equipped with a fixed base for easy positioning and assembly. By adjusting the small gear and large gear on the fixed plate that are assembled simultaneously, the guardrail is controlled to rotate, thereby causing the main fork and auxiliary fork to flip. When the main fork is in use, the spacing of the main fork can be controlled synchronously by adjusting the spacing of the disassembly and assembly components installed on the guardrail. Furthermore, the disassembly and assembly components, together with the support and positioning components, can effectively replace the main fork and adjust the spacing according to the size of the goods.

[0038] 2. This multi-functional electric forklift and its usage method are equipped with a fixed plate for easy support. When controlling the rotation of the rack, it can be combined with the assembly of the large gear and the main shaft, as well as the connection of the slider and the slide, to improve the stability of the rack's adjustment angle. When using the rack, the movement rod installed on the limit bar can be controlled by the cooperation of the built-in assembled spur gear and rack to adjust the distance between the relatively set assembly and disassembly components. The movement rod adopts a bent structure to increase the stability of the assembly and disassembly components during movement.

[0039] 3. The multi-functional electric forklift and its usage method are equipped with a disassembly and assembly component for assembling the main fork. The component is rotatably connected to a turntable, and controls the connecting rod to rotate, which drives the "L"-shaped locking block to adjust the relative extension and retraction, allowing for the replacement of the detachable main fork. Furthermore, the main fork, in conjunction with the support and positioning components installed by the disassembly and assembly component, effectively improves the stability of the main fork.

[0040] Furthermore, extendable and adjustable hydraulic rods are installed on the left and right sides of the outer surface of the rack. Through the nested installation between the positioning groove and the rotating seat, the position of the extendable rod can be controlled in conjunction with the telescopic component, thereby adjusting the angle of the rotating seat by the connecting rod two, thus controlling the angle of the auxiliary fork and the height of the auxiliary fork. This, combined with the rotation of the rack and the transfer of goods, improves the stability and convenience of use.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figures 1-8 The present invention provides a technical solution: a multi-functional electric forklift and its method of use, comprising an electric forklift body 1 that operates electrically, a first telescopic frame 2 installed on the left side of the outer surface of the electric forklift body 1, an inclined hydraulic cylinder 3 connected to the lower right section of the outer surface of the first telescopic frame 2, a second telescopic frame 4 telescopically connected to the middle section of the inner surface of the first telescopic frame 2, and a fixed seat 5 telescopically connected to the inner surface of the second telescopic frame 4.

[0053] Includes: a fixing plate 6, which is installed on the outer surface of the fixing base 5, and a small gear 7 is rotatably connected to the right side of the outer surface of the fixing plate 6, and a large gear 8 is meshed with the outer surface of the small gear 7. Meanwhile, a main shaft 9 is installed at the central shaft of the inner surface of the large gear 8, and a baffle 10 is installed on the outer surface of the main shaft 9.

[0054] The fixed base 5 and the fixed plate 6 form an integrated structure. The fixed plate 6 forms a meshing structure with the small gear 7 and the large gear 8. The large gear 8 forms a rotating structure with the barrier rack 10 through the main shaft 9. At the same time, the barrier rack 10 forms a nested sliding structure with the fixed plate 6 through the slider 11 and the slide groove 12. The slider 11 is set at an angle to the central axis of the outer surface of the barrier rack 10.

[0055] When in use, starting the electric forklift body 1 controls the telescopic adjustment between the first telescopic frame 2, the second telescopic frame 4, and the fixed base 5. In conjunction with the telescopic adjustment between the inclined hydraulic cylinder 3 installed on the first telescopic frame 2 and the electric forklift body 1, the angle of the main fork 22 can be adjusted. When the main fork 22 is flipped, the motor on the fixed plate 6 installed on the fixed base 5 can be controlled to drive the large gear 8 to rotate through the output shaft adjusting the small gear 7. The guard rack 10 assembled through the main shaft 9 installed on the large gear 8 can be controlled to rotate. When the guard rack 10 rotates, it can cooperate with the slider 11 installed at equal angles to slide in the groove 12 opened on the inner surface of the fixed plate 6 to limit the sliding, thereby improving the stability of the guard rack 10 during use.

[0056] The slider 11 is installed on the right side of the outer surface of the barrier rack 10, and the outer surface of the slider 11 is slidably connected to the groove 12 opened by the fixing plate 6. The inner surface of the barrier rack 10 is rotatably connected to the spur gear 13, and the outer surface of the spur gear 13 is meshed with the rack 14, and the outer surface of the rack 14 is equipped with the moving rod 15.

[0057] A limiting rod 16 is installed on the outer surface of the movable rod 15, and the limiting rod 16 slides on the side between the limiting plates 17 installed on the barrier shelf 10. A limiting groove 18 is opened on the inner surface of the limiting plate 17. Meanwhile, a disassembly assembly 19 is installed on the outer surface of the movable rod 15, and the disassembly assembly 19 slides in the limiting groove 18 at the connection between it and the movable rod 15.

[0058] Support member 20 is installed on the outer surface of disassembly assembly 19, and positioning member 21 is installed on the lower side of the outer surface of disassembly assembly 19. Main forks 22 are assembled on the outer surfaces of support member 20 and positioning member 21.

[0059] The baffle 10 is meshed with a spur gear 13 and a rack 14. The rack 14 is integrated with a moving rod 15 and a limiting rod 16. The moving rod 15 is limited and slidable with a limiting plate 17 via the limiting rod 16. The moving rod 15 is embedded in the outer surface of the disassembly assembly 19. The outer surface of the moving rod 15 is bent. The connection between the moving rod 15 and the disassembly assembly 19 is slidable with the limiting plate 17 via a limiting groove 18.

[0060] The inner surface of the disassembly assembly 19 is rotatably connected to a turntable 1901, and the outer surface of the turntable 1901 is rotatably connected to a connecting rod 1902. The other end of the outer surface of the connecting rod 1902 is rotatably connected to a locking block 1903. Meanwhile, a limiting block 1904 is installed on the outer surface of the locking block 1903, and the limiting block 1904 is slidably connected to the inner surface of the disassembly assembly 19. At the same time, the outer surface of the limiting block 1904 is limited and connected to the main fork 22.

[0061] The turntable 1901 and the disassembly assembly 19 form a rotating structure, and the disassembly assembly 19 forms a circumferential linear movement structure with the turntable 1901, the connecting rod 1902 and the limiting block 1904 and the locking block 1903. The locking block 1903 is symmetrically arranged about the middle section of the inner surface of the disassembly assembly 19, and the outer surface of the locking block 1903 is L-shaped. The locking block 1903 and the main fork 22 form a limiting engagement structure.

[0062] The support member 20, the disassembly assembly 19, and the positioning member 21 form an integrated structure. The disassembly assembly 19, through the support member 20 and the positioning member 21, forms a limiting support structure with the main fork 22. The outer surface of the support member 20 has an "L" shaped structure.

[0063] When adjustment of the spacing between the main forks 22 is required, the output shaft of the motor mounted on the retaining rack 10 can be rotated to control the meshing and adjustment of the spur gear 13 and rack 14. This also controls the sliding movement of the moving rod 15 mounted on the rack 14 and its assembled limiting rod 16 between the retaining rack 10 and the limiting plate 17, thereby controlling the stability of the moving rod 15 during movement and controlling the relative movement of the disassembly assembly 19 mounted on the moving rod 15. This controls the spacing between the main forks 22 on the disassembly assembly 19. Furthermore, during adjustment, the assembly position of the disassembly assembly 19 with the moving rod 15 is within the limiting groove 18 opened in the limiting plate 17. The limiting sliding improves the stability of the disassembly and assembly component 19 during use. The disassembly and assembly component 19, through the installed support 20 and positioning component 21, forms a positioning engagement with the main fork 22. It also controls the motor on the disassembly and assembly component 19 to rotate the turntable 1901, causing the rotating adjusting link 1902 to rotate relative to the locking block 1903. During the sliding adjustment of the locking block 1903, it cooperates with the installed limiting block 1904 to form a limiting adjustment, improving the stability of the locking block 1903. Furthermore, the locking block 1903, in conjunction with the main fork 22, forms a secondary engagement, thereby improving the stability of the device and allowing for control over the replacement of the main fork 22.

[0064] A lateral hydraulic cylinder 23 is installed on the outer side of the rack 10, and a hydraulic rod 24 is telescopically connected to the inner surface of the lateral hydraulic cylinder 23.

[0065] The lateral hydraulic cylinder 23 is embedded in the outer surface of the retaining rack 10, and the lateral hydraulic cylinder 23 forms a limiting telescopic structure with the auxiliary fork 26 through the hydraulic rod 24. The hydraulic rod 24 forms a nested installation structure with the auxiliary fork 26 through the positioning groove 25. At the same time, the rotating seat 27 forms a sliding limiting structure with the hydraulic rod 24.

[0066] A nested ring 2701 is rotatably connected to the lower side of the outer surface of the rotating seat 27, and the nested ring 2701 is installed on the upper side of the outer surface of the lateral hydraulic cylinder 23. A connecting rod 2702 is rotatably connected to the outer surface of the rotating seat 27, and a telescopic rod 2703 is rotatably connected to the other side of the outer surface of the connecting rod 2702. At the same time, a telescopic assembly 2704 is telescopically connected to the outer surface of the telescopic rod 2703, and a support seat 2705 is installed on the outer surface of the telescopic assembly 2704.

The outer surface of the connecting rod 2702 is bent, and the height of the outer surface of the telescopic component 2704 is lower than the height of the outer surface of the support seat 2705.

[0068] A method for using a multi-functional electric forklift includes the following steps:

[0069] Step 1: Start the electric forklift body 1 for the goods to be transferred, adjust the angle between the first telescopic frame 2 and the electric forklift body 1 by the assembled inclined hydraulic cylinder 3, and adjust the height of the guard rack 10 assembled on the fixed plate 6 installed on the fixed seat 5 by the extension and retraction of the second telescopic frame 4, and cooperate with the main forks 22 on the guard rack 10 to support the goods to be transferred.

[0070] Step 2: When using the backrest rack 10, the spur gear 13 of the assembled motor can be used to control the moving rod 15 installed on the rack 14, and the limiting rod 16 installed on the moving rod 15 can form a limiting slide between the limiting plate 17 and the backrest rack 10, thereby controlling the sliding of the disassembly and assembly component 19 installed on the moving rod 15 in the limiting groove 18, thereby controlling the spacing of the main fork 22 assembled by the disassembly and assembly component 19, and improving the stability of the main fork 22 when it moves;

[0071] Step 3: When different main forks 22 are required, the support member 20 assembled by the disassembly and assembly component 19 forms an upper locking support for the main fork 22, and forms a rotational locking during assembly. When the main fork 22 is vertically assembled after locking, the lower part of the main fork 22 is nested on the outer surface of the positioning member 21 to form a bottom support. The motor assembled by the disassembly and assembly component 19 is controlled to rotate the connecting rod 1902 connected to the turntable 1901 through the output shaft, and the rotating adjustment block 1903 is coordinated with the limit block 1904 to slide on the inner surface of the disassembly and assembly component 19, thereby controlling the block 1903 to fix the main fork 22 for a second time.

[0072] Step 4: When moving goods that need to be flipped, the main fork 22 can be used to provide support, and the lateral hydraulic cylinder 23 can be activated to control the auxiliary fork 26 mounted on the hydraulic rod 24 to move upward. This activates the telescopic assembly 2704 to drive the telescopic rod 2703 to retract and adjust the connecting rod 2702 to rotate. This also drives the rotating seat 27, which is rotatably connected to the nested ring 2701, to cooperate with the positioning groove 25 to control the hydraulic rod 24 to rotate and adjust. This also controls the auxiliary fork 26 to move downward and clamp the upper side of the goods. The motor on the fixed plate 6 is activated to control the small gear 7 and the large gear 8 to mesh and adjust the retaining rack 10 mounted on the main shaft 9 to rotate. This controls the flipping between the main fork 22 and the auxiliary fork 26, flipping the goods. When it is not necessary to flip the goods, the auxiliary fork 26 can also be used to position and clamp the upper end of the goods.

[0073] When goods need to be flipped during transport, the lateral hydraulic cylinder 23 can be activated to control the auxiliary fork 26 mounted on the hydraulic rod 24 to move upward and move the auxiliary fork 26 above the goods. This controls the telescopic assembly 2704 on the rack 10 to adjust the telescopic rod 2703 to retract, and drives the connecting rod 2702 to adjust the rotating seat 27 of the rotating assembly. Under the positioning of the nested ring 2701, and with the hydraulic rod 24 assembled in the positioning groove 25, the auxiliary fork 26 is rotated, thereby controlling the auxiliary fork 26 to rotate and position the auxiliary fork 26 above the goods. This allows the auxiliary fork 26 to move downward and contact the goods for clamping. At the same time, it can also work with the main fork 22 to control the rack 10 to flip, thereby flipping the goods for use and improving the stability of the electric forklift body 1.
