Description

Technical Field

[0001] This utility model relates to the field of auxiliary manual handling tooling technology, and in particular to an auxiliary tooling for pallet transfer. Background Technology

[0002] Currently, the transport vehicles for small chips typically use thin, sheet-like trays. These trays are usually made of plastic and have multiple small grooves on their upper surface for placing the chips. When transporting chips, the chips are placed in the grooves of the tray, and then multiple trays are stacked together. The multi-layered trays and chips can then be manually transported to their destination.

[0003] During the manual transfer process described above, the upper pallet is prone to tilting, which may cause the pallet to fall. If the pallets are stacked too high, the risk of the pallet falling during the handling process is even greater. Therefore, the number of pallets that can be handled manually at one time is limited, resulting in low handling efficiency. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides an auxiliary tooling for pallet transfer, thereby preventing pallets from falling during manual handling and improving pallet handling efficiency.

[0005] The technical solution adopted in this utility model is as follows: An auxiliary tooling for pallet transfer, wherein there are multiple pallets stacked vertically to form a pallet stack, the pallet stack having a first direction and a second direction perpendicular to each other, both the first direction and the second direction being perpendicular to the vertical; the auxiliary tooling includes: The first clamping part is located on one side of the pallet stack in the first direction; The second clamping part is disposed opposite to the first clamping part along the first direction, and the second clamping part corresponds to the other side of the pallet stack in the first direction; A sliding connection assembly includes multiple guide rods arranged side by side along the second direction, the axial direction of the guide rods being consistent with the first direction, and a first clamping part and / or a second clamping part slidingly engaging with the guide rods to change the distance between the first clamping part and the second clamping part; A locking assembly is used to detachably and securely connect the first clamping part and the second clamping part, so that after the pallet stack is located between the first clamping part and the second clamping part, it limits each pallet from a first direction, so that the pallets overlap vertically.

[0006] As a further improvement to the above technical solution: When the first clamping part slides with the guide rod, the end of the guide rod is provided with a first limiting part. The sliding connection assembly also includes a first linear bearing fixedly installed on the first clamping part. The first linear bearing is located between the first limiting part and the second clamping part and is used to limit the maximum distance between the first clamping part and the second clamping part. When the second clamping part slides with the guide rod, the end of the guide rod is provided with a second limiting part. The sliding connection assembly also includes a second linear bearing fixedly installed on the second clamping part. The second linear bearing is located between the second limiting part and the first clamping part and is used to limit the maximum distance between the second clamping part and the first clamping part.

[0007] It also includes a support section, which consists of two sections located at the lower ends of the first clamping section and the second clamping section, corresponding to the bottom of the pallet stack. When the distance between the first clamping part and the second clamping part is at its maximum, the distance between the support part at the bottom of the first clamping part and the support part at the bottom of the second clamping part along the first direction is greater than the dimension of the pallet stack along the first direction; After the locking assembly detachably and securely connects the first clamping part and the second clamping part, when the supporting part is located below the pallet stack, a U-shaped limiting space matching the shape of the pallet stack is formed between the supporting part, the first clamping part and the second clamping part.

[0008] When the first clamping part slides with the guide rod, a first fixing member is fixed on the guide rod, and a first elastic member is installed on the guide rod. The two ends of the first elastic member are in contact with the first fixing member and the first linear bearing, respectively, and provide elastic force along the first straight line direction toward the two ends of the guide rod. When the second clamping part slides with the guide rod, a second fixing member is fixed on the guide rod, and a second elastic member is installed on the guide rod. The two ends of the second elastic member are in contact with the second fixing member and the second linear bearing, respectively, and provide elastic force along the first linear direction toward the two ends of the guide rod.

[0009] It also includes a pair of extensions, one extension being fixedly connected to the first clamping part and the other extension being fixedly connected to the second clamping part; The locking assembly includes: The socket is located on an extension. The knob plunger is fixedly mounted on another extension. When the pin of the knob plunger is inserted into the socket, the first clamping part and the second clamping part are detachably and fixedly connected.

[0010] The knob plunger is a reset type, and the extension of the socket is also provided with a guide slope, which is used to guide the pin of the knob plunger into the socket.

[0011] The number of knob plungers is one.

[0012] Each extension is equipped with a gripping part.

[0013] It also includes two side stops arranged along the second direction, each side stop being fixedly connected to the first clamping part and / or the second clamping part, and the two side stops respectively limiting the pallet stack from both sides of the pallet stack in the second direction.

[0014] The lower part of the side baffle is provided with a guide structure for guiding the pallet stack from below the auxiliary tooling into the space between the two side baffles.

[0015] The beneficial effects of this utility model are as follows: This utility model has a compact and reasonable structure and is easy to operate. It uses multiple guide rods to slide and connect a first clamping part and / or a second clamping part arranged along the first direction of the pallet stack, so that the distance between the first clamping part and the second clamping part can be changed. After the distance between the first clamping part and the second clamping part is fixed by the locking assembly, the pallet is limited from the first direction, maintaining the stability of the pallet stack along the vertical stack. This prevents the pallet from falling during manual handling, while increasing the number of pallets and improving the pallet handling efficiency.

[0016] This utility model also has the following advantages: (1) A limiting part is provided at the end of the guide rod to prevent the first clamping part or the second clamping part from disengaging from the guide rod, thereby improving the ease of operation of the auxiliary tooling.

[0017] (2) A support part is provided on the first clamping part and the second clamping part to limit the pallet stack in the vertical direction of the pallet stack, so as to prevent the pallet stack from falling off the auxiliary tooling from the bottom. Alternatively, the pallet stack can be dragged from below by the support part. Operators can choose to move the pallet stack directly or the auxiliary tooling according to their needs, thereby improving the applicability of the auxiliary tooling.

[0018] (3) By setting a compressible elastic element on the guide rod, the first clamping part and the second clamping part automatically open away from the pallet stack after the locking component is released by the restoring force of the elastic element under compression, thereby improving the convenience of auxiliary tooling operation. When both the first clamping part and the second clamping part are slidably engaged with the guide rod, after the locking component is released, the first clamping part and the second clamping part move simultaneously relative to the pallet stack. When they are in position, the first clamping part and the second clamping part do not contact the pallet stack, and the auxiliary tooling can be lifted directly upwards, which facilitates the separation operation of the auxiliary tooling from the pallet stack.

[0019] (4) The locking component is designed as a knob plunger and a socket connection structure, which is simple and easy to operate.

[0020] (5) The gripping part on the extension can facilitate the operator to move the first clamping part and the second clamping part with one hand, and also facilitate the operator to hold it. The pallet stack can be moved by the operator by lifting the pallet stack with one hand using the auxiliary tool, thereby increasing the number of pallet stacks that the operator can move.

[0021] (6) The ease of operation of the auxiliary tooling is further improved by using the grip part in conjunction with the reset knob plunger.

[0022] (7) The side stop provided along the second direction, together with the first clamping part and the second clamping part provided along the second direction, limits the pallet stack from two mutually perpendicular horizontal directions, further ensuring the stability of the pallet stacked vertically.

[0023] (8) A guide structure is provided at the lower part of the side guards so that the distance between the fixed side guards is adapted to the second direction dimension of the pallet stack, while facilitating the assembly of the auxiliary tooling with the pallet stack, and making the limiting effect of the auxiliary tooling in the second direction better.

Support base. Detailed Implementation

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] Example 1: like Figures 1-3 As shown, the auxiliary tooling for pallet transfer in this embodiment includes multiple pallets 61, which are stacked vertically to form a pallet stack 6. The pallet stack 6 has a first direction and a second direction that are perpendicular to each other. Both the first direction and the second direction are perpendicular to the vertical. The auxiliary tooling includes a first clamping part 41, a second clamping part 42, a sliding connection assembly 2, and a locking assembly 3.

[0035] The first clamping part 41 corresponds to one side of the pallet stack 6 in the first direction; The second clamping part 42 is disposed opposite to the first clamping part 41 along the first direction, and the second clamping part 42 corresponds to the other side of the pallet stack 6 in the first direction; The sliding connection assembly 2 includes multiple guide rods 25 arranged side by side along the second direction. The axial direction of the guide rods 25 is consistent with the first direction. The first clamping part 41 and / or the second clamping part 42 slides with the guide rods 25 to change the distance between the first clamping part 41 and the second clamping part 42. The locking assembly 3 is used to detachably and fix the first clamping part 41 and the second clamping part 42 so that the pallet stack 6 is located between the first clamping part 41 and the second clamping part 42 and then limits each pallet 61 from the first direction so that the pallets 61 overlap vertically.

[0036] like Figure 4 As shown, this is a specific embodiment in which the first clamping part 41 and the second clamping part 42 are slidably engaged with the guide rod 25.

[0037] In this embodiment, the first clamping part 41 can be fixed to the guide rod 25, and the second clamping part 42 can be slidably engaged with the guide rod 25, or the second clamping part 42 can be fixed to the guide rod 25, and the first clamping part 41 can be slidably engaged with the guide rod 25. As long as the distance between the first clamping part 41 and the second clamping part 42 can be changed along the first direction, the surfaces of the first clamping part 41 and the second clamping part 42 facing each other are planes and they are always kept parallel to each other.

[0038] like Figures 2-3 As shown, the shape of a single pallet 61 is a rectangular sheet with specific dimensions of 300mm × 130mm. When the locking assembly 3 detachably and securely connects the first clamping part 41 and the second clamping part 42, the distance between the first clamping part 41 and the second clamping part 42 is locked. At this time, both the first clamping part 41 and the second clamping part 42 can be in contact with the pallet stack 6, clamping the pallet stack 6 from the first direction. The clamping force can limit the relative displacement of the pallet 61 in the pallet stack 6 along the second direction, ensuring the shape stability of the pallet stack 6 during transportation and preventing the pallet 61 from falling off during transportation.

[0039] In addition, when the shape of a single pallet 61 is circular or elliptical, the first clamping part 41 and the second clamping part 42 are both shaped to fit the shape of the pallet 61. When the distance between the first clamping part 41 and the second clamping part 42 is locked by the locking component 3, the first clamping part 41 and the second clamping part 42 simultaneously limit the pallet stack 6 from the first direction and the second direction to prevent the vertical position of the pallet 61 in the pallet stack 6 from deviating from that of the adjacent pallet 61 during the handling process.

[0040] In addition, if the distance between the first clamping part 41 and the second clamping part 42 is slightly greater than the size of the pallet stack 6 along the first direction, it is also possible to prevent the pallet stack 6 from tilting by simply limiting the pallet stack 6 from the side in the first direction.

[0041] The first clamping part 41 and the second clamping part 42 limit each pallet 61 of the pallet stack 6 from the first direction, keeping the pallets 61 overlapping vertically to increase the number of pallets 61 and improve the safety of the pallets 61 during handling.

[0042] The specific usage process of the auxiliary tooling in this embodiment is as follows: The pallet stack 6 to be transported is supported by the support base 8, which allows the bottom pallet 61 of the pallet stack 6 to be suspended in the air; After the auxiliary tooling is lowered, the distance between the first clamping part 41 and the second clamping part 42 is adjusted so that the pallet stack 6 is located between the first clamping part 41 and the second clamping part 42. The locking assembly 3 is used to fix the distance between the first clamping part 41 and the second clamping part 42, ensuring the stability of the stacking posture of the pallet stack 6. Figure 2 As shown; When manually moving pallet stack 6, the bottom pallet of pallet stack 6 can be supported by both hands. During the moving process, the pallet stack 6 can be limited from both sides in the second direction, and the auxiliary tooling and pallet stack 6 can be moved together to the support seat 8 of the next station. Figure 3 As shown; Then, after releasing the locking effect of the locking assembly 3, the first clamping part 41 and the second clamping part 42 are moved to separate the auxiliary tooling from the pallet stack 6.

[0043] In one specific embodiment, the number of guide rods 25 is two, such as Figure 1 As shown, the sliding guidance of the first clamping part 41 and the second clamping part 42 along the first direction is satisfied, so as to realize the smooth movement of the first clamping part 41 and the second clamping part 42.

[0044] Multiple guide rods 25 are slidably connected to a first clamping part 41 and / or a second clamping part 42 arranged along the first direction of the pallet stack 6, so that the distance between the first clamping part 41 and the second clamping part 42 can be changed. After the distance between the first clamping part 41 and the second clamping part 42 is fixed by the locking assembly 3, the pallet 61 is limited from the first direction, maintaining the stability of the pallet stack 6 stacked vertically. This prevents the pallet 61 from falling during manual handling, while increasing the number of pallets 61 and improving the handling efficiency of the pallet 61.

[0045] In this embodiment, as Figure 6 As shown: When the first clamping part 41 slides with the guide rod 25, the end of the guide rod 25 is provided with a first limiting part 211. The sliding connection assembly 2 also includes a first linear bearing 221 fixedly installed on the first clamping part 41. The first linear bearing 221 is located between the first limiting part 211 and the second clamping part 42, and is used to limit the maximum distance between the first clamping part 41 and the second clamping part 42. When the second clamping part 42 is slidably engaged with the guide rod 25, the end of the guide rod 25 is provided with a second limiting part 212. The sliding connection assembly 2 also includes a second linear bearing 222 fixedly installed on the second clamping part 42. The second linear bearing 222 is located between the second limiting part 212 and the first clamping part 41 and is used to limit the maximum distance between the second clamping part 42 and the first clamping part 41.

[0046] Specifically, such as Figure 6As shown, the outer diameter of the first limiting part 211 and the second limiting part 212 is larger than the outer diameter of the guide rod 25. The first limiting part 211 and the second limiting part 212 are block-shaped and can be detachably installed at the end of the guide rod 25 by fasteners.

[0047] A limiting part is provided at the end of the guide rod 25 to prevent the first clamping part 41 or the second clamping part 42 from disengaging from the guide rod 25, thereby improving the ease of operation of the auxiliary tooling.

[0048] Example 2: Based on Example 1, such as Figure 4 , Figure 5 As shown, the auxiliary tooling for pallet transfer in this embodiment also includes a support part 7. There are two support parts 7, which are located at the lower ends of the first clamping part 41 and the second clamping part 42, respectively, corresponding to the bottom of the pallet stack 6. When the distance between the first clamping part 41 and the second clamping part 42 is at its maximum, the distance between the support part 7 at the bottom of the first clamping part 41 and the support part 7 at the bottom of the second clamping part 42 along the first direction is greater than the dimension of the pallet stack 6 along the first direction. After the locking assembly 3 detachably and securely connects the first clamping part 41 and the second clamping part 42, when the supporting part 7 is located below the pallet stack 6, a U-shaped limiting space matching the shape of the pallet stack 6 is formed between the supporting part 7, the first clamping part 41 and the second clamping part 42.

[0049] A support part 7 is provided on the first clamping part 41 and the second clamping part 42 to limit the pallet stack 6 in the vertical direction, so as to prevent the pallet stack 6 from detaching from the bottom of the auxiliary tooling. Alternatively, the support part 7 can be used to support the pallet stack 6 from below. Operators can choose to move the pallet stack 6 directly or the auxiliary tooling as needed, thereby improving the applicability of the auxiliary tooling.

[0050] Example 3 Based on the above embodiments, in order to improve the ease of operation of the auxiliary operating tooling, such as Figure 7 As shown in Figure 8, in this embodiment, the auxiliary tooling for pallet transfer includes: When the first clamping part 41 slides with the guide rod 25, the guide rod 25 is fixed with a first fixing member 241 and a first elastic member 231 is installed on the guide rod 25. The two ends of the first elastic member 231 are in contact with the first fixing member 241 and the first linear bearing 221 respectively, and provide elastic force towards the two ends of the guide rod 25 along the first linear direction. When the second clamping part 42 slides with the guide rod 25, the guide rod 25 is fixed with a second fixing member 242 and a second elastic member 232 is installed on the guide rod 25. The two ends of the second elastic member 232 are in contact with the second fixing member 242 and the second linear bearing 222 respectively, and provide elastic force towards the two ends of the guide rod 25 along the first linear direction.

[0051] Specifically, both the first elastic element 231 and the second elastic element 232 are compression springs in a compressed state. After compression, the first elastic element 231 allows the first clamping part 41 to move toward the second clamping part 42. After the locking assembly 3 releases the fixation of the first clamping part 41 and the second clamping part 42, the first clamping part 41 returns to the position furthest from the second clamping part 42 under the elastic force of the first elastic element 231 and is then limited by the first limiting part 211. The function of the second elastic element 232 is the same.

[0052] like Figure 8 As shown, both the first fixing member 241 and the second fixing member 242 include an annular body. The annular body is provided with a fixing hole 240, which penetrates the annular body radially. The guide rod 25 is provided with a groove 250 corresponding to the fixing hole 240. The fixing hole 240 is a threaded hole. After a bolt is installed in the fixing hole 240, the end of the bolt extends into the groove 250 of the guide rod 25, thereby fixing the annular body to the guide rod 25.

[0053] By setting a compressible elastic element on the guide rod 25, the first clamping part 41 and the second clamping part 42 automatically open away from the pallet stack 6 after the locking function of the locking assembly 3 is released by the restoring force of the elastic element under the compressed state, thereby improving the convenience of auxiliary tooling operation.

[0054] When both the first clamping part 41 and the second clamping part 42 are slidably engaged with the guide rod 25, after the locking assembly 3 is released, the first clamping part 41 and the second clamping part 42 move simultaneously relative to the pallet stack 6. When they are in position, the first clamping part 41 and the second clamping part 42 do not contact the pallet stack 6, and the auxiliary tooling can be lifted directly upwards, which facilitates the separation operation of the auxiliary tooling from the pallet stack 6.

[0055] Furthermore, such as Figure 4 , Figure 7 As shown, the auxiliary tooling for pallet transfer in this embodiment also includes a pair of extensions 1, one extension 1 being fixedly connected to the first clamping part 41, and the other extension 1 being fixedly connected to the second clamping part 42.

[0056] The locking assembly 3 includes a socket 32 ​​and a knob plunger 31.

[0057] The socket 32 ​​is located on an extension 1; A knob plunger 31 is fixedly mounted on another extension 1; When the pin 311 of the knob plunger 31 is inserted into the socket 32, the first clamping part 41 and the second clamping part 42 are detachably and fixedly connected.

[0058] Specifically, when handling pallet stack 6, both the extension 1 and the guide rod 25 are positioned above pallet stack 6; as Figure 1 As shown, the extension 1, the first clamping part 41, and the second clamping part 42 are all plate-shaped. The first clamping part 41 and the second clamping part 42 are perpendicular to the extension 1. The first clamping part 41 and the second clamping part 42 can be a separate structure from the extension 1, but they are assembled together with fasteners. Right-angled connecting blocks are used to ensure the perpendicularity of the extension 1 with the first clamping part 41 and the second clamping part 42. In order to reduce the weight of the auxiliary tooling, the first clamping part 41 and the second clamping part 42 are provided with weight-reducing holes. Reinforcing ribs can also be provided to improve the flatness of the first clamping part 41 and the second clamping part 42.

[0059] The locking assembly 3 is designed with a simple structure in which a knob plunger 31 and a socket 32 ​​are inserted. It is easy to operate.

[0060] In another specific implementation, such as Figure 4 , Figure 7 As shown, the selector knob plunger 31 is a reset type. The extension 1 with the insertion hole 32 is also provided with a guide slope 33. The guide slope 33 is used to guide the pin head 311 of the knob plunger 31 into the insertion hole 32.

[0061] like Figure 4 , Figure 7 As shown, when the first clamping part 41 and the second clamping part 42 move relative to each other, the moving direction of the pin head 311 of the knob plunger 31 is directly opposite to the tilting direction of the guide slope 33; a mounting plate 34 is detachably mounted on the extension 1 of the fixedly mounted knob plunger 31, and the knob plunger 31 is detachably mounted on the mounting plate 34, which simplifies the structure of the extension 1 and also facilitates the adjustment of the number of knob plungers 31. If two knob plungers 31 are required, an additional mounting plate 34 and a socket 32 ​​can be added.

[0062] In another specific implementation, such as Figure 4 , Figure 7 As shown, there is one knob plunger 31. Each extension 1 is provided with a gripping part 10.

[0063] like Figure 4As shown, the grip 10 is a through-hole structure penetrating the extension 1. The grip 10 can also be a handle fixed to the extension 1. The distance between the two grips 10 is adapted to the size of the operator's palm. When the two grips 10 are gripped with one hand, the first clamping part 41 and the second clamping part 42 move relative to each other. When the first clamping part 41 and the second clamping part 42 clamp the pallet stack 6 from both sides of the pallet stack 6, the pin head 311 of the knob plunger 31 is aligned with the insertion hole 32. The other hand can be used to operate the knob plunger 31 so that the pin head 311 of the knob plunger 31 is inserted into the insertion hole 32. If the knob plunger 31 is in reset position... The first clamping part 41 and the second clamping part 42 can be moved relative to each other by pinching the two gripping parts 10 with one hand. After this, the pin head 311 will automatically insert into the insertion hole 32. When it is necessary to release the fixed connection between the first clamping part 41 and the second clamping part 42, one hand can hold the gripping part 10 while the other hand pulls the pin head 311 out of the insertion hole 32. In addition, when the lower end of the first clamping part 41 and the second clamping part 42 is provided with the support part 7, after the locking component 3 fixes the distance between the first clamping part 41 and the second clamping part 42, the operator can grasp the gripping part 10 with one hand, lift the auxiliary tooling, and carry out the pallet stack 6.

[0064] The gripping part 10 provided on the extension part 1 makes it easy for the operator to move the first clamping part 41 and the second clamping part 42 with one hand. It also makes it easy for the operator to hold the pallet stack 6. The pallet stack 6 can be moved by lifting the pallet stack 6 with one hand using the auxiliary tool, thereby increasing the number of pallet stacks 6 that the operator can move.

[0065] The use of the grip 10 in conjunction with the reset knob plunger 31 further improves the ease of operation of the auxiliary tooling.

[0066] Example 4: Based on the above embodiments, the auxiliary tooling for pallet transfer in this embodiment also includes two side stops 5 arranged along the second direction. Each side stop 5 is fixedly connected to the first clamping part 41 and / or the second clamping part 42. The two side stops 5 limit the pallet stack 6 from both sides of the pallet stack 6 in the second direction.

[0067] The side stop 5, which is arranged along the second direction, together with the first clamping part 41 and the second clamping part 42, which are arranged along the second direction, limit the pallet stack 6 from two mutually perpendicular horizontal directions, further ensuring the stability of the pallet 61 when stacked vertically.

[0068] The number of side guards 5 can be four, with two located on one side of the pallet stack 6 in the first direction and fixedly connected to two extensions 1 respectively, and two located on the other side of the pallet stack 6 in the first direction and fixedly connected to two extensions 1 respectively; provided that the second direction limit can be achieved, the total number of the two side guards 5 can be two or three.

[0069] like Figure 2 , Figure 3 As shown, the lower part of the side stop 5 is provided with a guide structure 51, which is used to guide the pallet stack 6 from below the auxiliary tooling into the space between the two side stops 5.

[0070] Specifically, the side baffle 5 can be a plate-shaped structure or a standard column-shaped component—a smooth rod. The upper end of the smooth rod is fixedly connected to the extension 1, and the lower end of the smooth rod is provided with a rounded chamfer as a guide structure 51. When the auxiliary tooling moves downward from above the pallet stack 6, the guide structure 51 contacts the two sides of the pallet stack 6 in the second direction and guides the auxiliary tooling to move.

[0071] A guide structure 51 is provided at the lower part of the side stop 5 so that the distance between the fixedly installed side stop 5 is adapted to the second direction dimension of the pallet stack 6, while facilitating the assembly of the auxiliary tooling with the pallet stack 6 and making the limiting effect of the auxiliary tooling in the second direction better.

[0072] The specific usage process of the auxiliary tooling in this embodiment is as follows: The pallet stack 6 to be moved is supported by the support base 8, with the bottom pallet 61 of the pallet stack 6 suspended in the air, as... Figure 3 (a); With the distance between the first clamping part 41 and the second clamping part 42 at its maximum, the auxiliary tooling is placed at the top of the pallet stack 6. The auxiliary tooling is then moved downwards, and after the guide structure 51 contacts the pallet stack 6, it guides the pallet stack 6 between the two side stops 5. Simultaneously, the first clamping part 41 and the second clamping part 42 are located on both sides of the pallet stack 6, covering the outside of the pallet stack 6 with the first clamping part 41, the second clamping part 42, and the side stops 5. Figure 3 (a); The auxiliary tooling descends to a position where the support part 7 is located below the lowest pallet 61 of the pallet stack 6. After gripping both gripping parts 10 with one hand, the first clamping part 41 and the second clamping part 42 move relative to each other. The pin 311 of the reset-type rotary plunger 31 automatically inserts into the insertion hole 32. The first clamping part 41 and the second clamping part 42 together limit the pallet stack 6 from two mutually perpendicular horizontal directions. The support part 7 limits the pallet stack 6 from a vertical direction. Figure 3 (b); The operator uses the gripping part 10 to lift and move the pallet stack 6 with one hand using auxiliary tooling, such as... Figure 3 (c); After the pallet stack 6 is placed back on a support base 8, while holding the gripping part 10 with one hand, the pin head 311 is pulled out of the socket 32 ​​with the other hand. The first clamping part 41 and the second clamping part 42 move away from each other. Then, one hand lifts the gripping part 10 to move the auxiliary tooling upward and separate the auxiliary tooling from the pallet stack 6.
