Description

Technical Field

[0001] The invention relates to the technical field of stackers, and in particular to a storage aisle type stacker. Background Art

[0002] The stacker is mainly composed of a lower beam, a loading platform, a fork mechanism, a column, an upper beam, a horizontal operating mechanism, a lifting mechanism, an electric control cabinet, a safety protection device and an electrical control system. Its purpose is to shuttle back and forth between the aisles of the three-dimensional warehouse. It can store the goods at the entrance of the aisle into the cargo grid, or take the goods out of the cargo grid and transport them to the entrance of the aisle through manual, semi-automatic or fully automatic operation.

[0003] In order to improve the storage efficiency of the warehouse, the size of the aisle and the size of the stacker will be as small as possible to make more shelves. The smaller the stacker, the shorter the maximum extension of the fork, which is not conducive to the storage depth of the goods on the shelf. The greater the storage depth of the goods on the shelf, the stronger the ability to store goods on the shelf. For this reason, the maximum extension of the stacker fork has been improved in the prior art. For example, the invention patent with application number CN202310347889.X and publication (announcement) number CN116513675A discloses "a stacker, a three-dimensional warehouse structure containing a stacker, and a cargo conveying method, a stacker, including a stacker body, a fork assembly, a Z-axis motion mechanism, a two-way conveying mechanism with variable overhang, and a stacker electronic control unit". In the invention, the stacker overhang length can be adjusted by freely adjusting the position of the fork assembly to meet the use in a three-dimensional warehouse with different specifications of shelf spacing.

[0004] The above invention patent actually increases the maximum running length of the fork by adding a horizontal running track and using a double-layer running track, thereby increasing the maximum extension of the fork. However, during the actual operation, the inventor found that it has at least the following shortcomings: when the fork is supporting the goods, the gravity of the goods will be partially applied to the horizontal running track of the fork. After long-term pressure from the goods, the horizontal running track itself is prone to downward deformation. Once the horizontal running track of the fork is deformed downward, it will cause the horizontal running track to get stuck and the fork cannot be fully retracted. After adding an additional horizontal running track, as long as one of the additional horizontal running track and the original horizontal running track is deformed downward, it will inevitably cause the horizontal running track to get stuck, which undoubtedly increases the probability of the horizontal running track getting stuck. Therefore, how to still achieve the addition of a horizontal running track of the fork to increase the maximum extension of the fork, even if the additional horizontal running track is deformed downward, it will not cause the horizontal running track to get stuck is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The object of the present invention is to provide a storage aisle type stacker to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a storage aisle stacker, comprising a fork, a first horizontal running track, and a second horizontal running track.

[0007] The first horizontal running track includes a base fixedly mounted on a fixed seat and a slide seat slidably plugged with the base, the second horizontal running track includes a slideway opened on the slide seat and a rotating shaft rotatably plugged on the fork, the fork is buckled on the outside of the slide seat, and the rotating shaft passes through the slideway and slides along the length direction of the slideway;

[0008] The cam is engaged with the gear plate and the gear is engaged with the gear to move along the guide rail.

[0009] In the above-mentioned warehouse aisle stacker, the power input end of the transmission member is meshed with the linkage gear set, and the power output end of the transmission member is elastically slidably plugged with the fork so that the power output end of the transmission member can pull the fork to slide, and at the same time, the end of the fork away from the rotating shaft is elastically tilted. When the fork lifts the goods, the fork is pressed down by the gravity of the goods to elastically rotate to buffer the goods, and at the same time, the power output end of the linkage member protrudes from the fork to prevent the goods from sliding down.

[0010] For the above-mentioned storage aisle stacker, when the downward deformation of the second horizontal running track increases, the length of the power output end of the transmission member protruding from the fork increases when driving the fork to lift the goods, thereby judging the degree of deformation generated by the second horizontal running track.

[0011] In the above-mentioned warehouse aisle stacker, when the cargo fork lifts the cargo, the inner top surface of the cargo fork abuts against the top surface of the slide seat.

[0012] The above-mentioned warehouse aisle stacker, the driving part includes a first motor and a driving gear coaxially fixedly mounted on the output shaft of the first motor, the bottom of the slide is provided with a transmission tooth meshing with the driving gear, the first motor drives the driving gear to rotate forward and reverse, based on the meshing of the driving gear and the transmission tooth, the driving gear drives the slide to slide back and forth along the length direction of the base when it rotates.

[0013] In the above-mentioned warehouse aisle stacker, the interlocking gear set includes a main gear rotatably mounted on a slide, the main gear is located above the toothed plate and meshes with the toothed plate so that the main gear is driven to rotate when the slide slides, and the power input end of the transmission member is located above the main gear and meshes with the main gear so that the transmission member is driven to slide when the main gear rotates.

[0014] In the above-mentioned warehouse aisle stacker, the interlocking gear group also includes an interlocking gear coaxially fixedly connected to the main gear. There are multiple interlocking gear groups and they are arrayed along the length direction of the slide. The multiple interlocking gears arrayed along the length of the slide are connected by chain transmission.

[0015] The above-mentioned warehouse aisle stacker, the transmission member includes a sliding plate slidably inserted along the length direction of the slide seat and a pull rod fixedly connected to the sliding plate, the bottom of the sliding plate is provided with meshing teeth meshing with the main gear, the pull rod is slidably inserted with the fork, the pull rod is provided with a compression spring elastically abutting against the fork, the pull rod is arc-shaped and the center of the arc is located on the axis center line of the rotating shaft, the meshing teeth are the power input end of the transmission member, and the pull rod is the power output end of the transmission member.

[0016] The above-mentioned warehouse aisle stacker has a through hole for inserting a pull rod on the fork, and the through hole includes an upper receiving hole and a lower guide hole connected up and down, and the diameter of the upper receiving hole is larger than the diameter of the lower guide hole. The pull rod includes a rod body and a limiting cap that are fixedly connected. In the initial state, the limiting cap is located in the upper receiving hole and abuts against the top of the lower guide hole to limit the fork.

[0017] In the above-mentioned storage aisle stacker, a roller is rotatably provided on the slide, and the top of the roller is at the same height as the top of the slide so as to reduce the friction between the fork and the slide when the inner top surface of the fork abuts against the top surface of the slide.

[0018] Beneficial effect: In the above technical scheme, the invention provides a storage aisle type stacker, which can not only drive the synchronous movement of the fork when the slide seat slides, but also drive the fork and the slide seat to slide relative to each other, thereby increasing the elongation of the fork, and realizes the relative sliding between the fork and the slide seat by sliding connection between the rotating shaft installed at one end of the fork and the slideway provided on the slide seat. If the second horizontal running track is deformed downward, it must be caused by the bending deformation of the rotating shaft or the deformation of the hole where the slideway and the rotating shaft are plugged in. The rotating shaft is cylindrical, and there is a linear gap between it and the slideway. The two ends of the slideway must be radially deformed when the shaft is deformed, and the deformation at the hole where the slideway and the shaft are plugged will not affect the shape of the shaft inside the slideway, so that the shaft can still slide along the length direction of the slideway, and the shaft will not get stuck, so that the fork will not get stuck. Therefore, the present invention can still achieve the addition of a horizontal running track for the fork to increase the maximum extension of the fork, and even if the added horizontal running track is deformed downward, it will not cause the horizontal running track to get stuck, which can effectively solve the shortcomings of the prior art.

[0019] At the same time, in the present invention, since only one end of the fork is connected to the slide seat by the rotating shaft, the end of the fork away from the rotating shaft can move up and down, so that when the fork is deformed downward after a long-term load, the fork can rotate freely when the fork is recovered, and the fork can still be completely recovered, and there will be no jamming between the fork and the slide seat. It can be seen that in the present invention, whether the second horizontal running track is deformed downward or the fork is deformed downward, it will not cause the fork to be stuck;

[0020] Furthermore, the special design of the present invention enables the power input end of the transmission member to achieve multiple unexpected technical effects, greatly improving the utilization rate. Specifically: since the power output end of the transmission member is plugged into the fork up and down, the power output end of the transmission member drives the fork to move, which is one of the functions of the power output end of the transmission member; furthermore, since the fork is elastically plugged into the power output end of the transmission member, the end of the fork away from the rotating shaft is elastically tilted, so that when the fork lifts the goods, the fork can be pressed down to rotate elastically around the rotating shaft based on the gravity of the goods, and the power output end of the transmission member plays a role in buffering the goods; furthermore, when the fork rotates downward, the power output end of the transmission member will not rotate, and the power output end of the transmission member will gradually protrude from the top of the fork. At this time, the goods are located on the inner side of the power output end of the transmission member. Since the top of the fork will be uneven when the fork or the rotating shaft is deformed downward, the goods on the fork will tilt toward the power output end of the transmission member. At this time, it is easy to cause the goods to slip during transportation. The present invention cleverly uses the power output end of the transmission member protruding from the top of the fork, so that the power output end of the transmission member has the function of blocking the goods, which can effectively prevent the goods from slipping, and has an unexpected technical effect.

[0021] Furthermore, when the second horizontal running track is deformed downward or the fork is deformed downward, when the fork lifts the goods and drives the fork to rotate to the lowest point, the length of the power output end protruding from the fork will increase, so that it can be determined that the second horizontal running track or the fork has been deformed downward. It can be seen that the power output end of the transmission member also plays a role in detecting whether the second horizontal running track and the fork have been deformed downward.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-11 As shown, a storage aisle stacker provided by an embodiment of the present invention comprises a fork 3, a first horizontal running track, and a second horizontal running track. The first horizontal running track comprises a base 1 fixedly mounted on a fixed seat 10 and a slide 2 slidably plugged with the base 1. The second horizontal running track comprises a slide 201 provided on the slide 2 and a rotating shaft 301 rotatably plugged on the fork 3. The fork 3 is buckled on the outside of the slide 2. The rotating shaft 301 passes through the slide 201 and slides along the length direction of the slide 201.

[0038] It also includes a driving member for driving the slide 2 to slide and a fixed tooth plate 7. The slide 2 is provided with a linkage gear set meshing with the tooth plate 7. The linkage gear set is linked to the fork 3 through a transmission member. When the driving member drives the slide 2 to slide horizontally, the fork 3 moves synchronously with the slide 2. At the same time, based on the meshing of the linkage gear set and the tooth plate 7, the linkage gear set rotates to drive the transmission member to pull the fork 3 to drive the rotating shaft 301 to slide along the slideway 201.

[0039] The storage aisle stacker provided in this embodiment is used to move goods to shelves, or move goods on shelves out of the warehouse, and the goods are placed on pallets. The words related to directions and positions involved are relative to the drawings, and the "chain" in this embodiment is not given in the drawings. Specifically, the storage aisle stacker includes a fixedly connected column 18, an upper beam 19, a cargo platform 11, a horizontal operating mechanism, a lifting mechanism, and an operating box 17, wherein the horizontal operating mechanism includes a fixedly installed horizontal guide beam 20, a horizontal guide wheel 21 rotatably set on the upper beam 19, and a power output mechanism for driving the upper beam 19 to move horizontally, and the lifting mechanism includes a second motor 15 installed on the column 18, and the power output end of the second motor 15 is equipped with a retractable roller 16, and the upper beam 19 is rotatably installed with a plurality of fixed rollers. The directional wheel 22, the left and right sides of the cargo platform 11 are fixedly installed with connecting boxes 14, the number of connecting boxes 14 and the number of columns 18 are both two and correspond one to one, the two connecting boxes 14 are located between the two columns 18, a group of avoidance holes 1401 are opened on the connecting box 14, a wheel is rotatably installed in the connecting box 14, a rope is installed between the wheel and the retracting roller 16, the rope passes around the directional wheel 22, and the retracting roller 16 is driven to rotate by starting the second motor 15 to realize the up and down sliding of the cargo platform 11. The above structures are all existing technologies and are not described in detail. In order to improve the smoothness and stability of the up and down movement of the cargo platform 11, in this embodiment, a group of left and right auxiliary wheels 24 and a group of front and rear auxiliary wheels 23 are rotatably arranged on the outer side of the connecting box 14, and the group of left and right auxiliary wheels 24 and the group of front and rear auxiliary wheels 23 are both abutted against the corresponding columns 18. A group of left and right auxiliary wheels 24 is used to limit the connecting box 14 from shaking left and right, and a group of front and rear auxiliary wheels 23 is used to limit the connecting box 14 from shaking front and back, thereby improving the smoothness and stability of the cargo platform 11 when moving up and down.

[0040] Among them, the fixed seat 10 is fixedly installed on the cargo platform 11 and moves synchronously with the movement of the cargo platform 11. The fixed seat 10 is divided into two groups. A base 1 is fixedly installed on each group of fixed seats 10. The cross-section of the base 1 is in a "cross" shape or a "T" shape or other shapes. As long as the slide 2 and the base 1 can slide relative to each other and the slide 2 will not separate from the base 1 from the vertical direction during the sliding process, a bottom slide groove 205 compatible with the base 1 is opened at the bottom of the slide 2. The base 1 is slidably inserted in the bottom slide groove 205, and the base 1 and the slide 2 form a first horizontal running track. A fork 3 is slidably arranged on each slide 2, wherein a slideway 201 provided on the slide 2 is arranged along the length direction of the slide 2, a rotating shaft 301 rotatably mounted on the fork 3 is located at one end of the fork 3, the rotating shaft 301 passes through the slideway 201 and is slidably arranged along the length direction of the slideway 201, the rotating shaft 301 and the slideway 201 form a second horizontal running track, the fork 3 is buckled on the outside of the slide 2, when the slide 2 slides, the fork 3 is driven to slide synchronously, and the sliding of the slide 2 is driven by the driving member, and at the same time A linkage gear set is rotatably arranged on the slide 2, and a tooth plate 7 meshing with the linkage gear set is fixedly installed on the fixed seat 10. Since the tooth plate 7 does not move when the slide 2 slides, and the linkage gear set moves synchronously with the slide 2, based on the meshing of the linkage gear set and the tooth plate 7, the linkage gear set moves and rotates at the same time, and the rotation of the linkage gear set drives the transmission member to move, and the transmission member then pulls the fork 3 to move, so that the fork 3 moves synchronously with the slide 2 while sliding relative to the slide 2 under the pulling force of the transmission member, and then The running length of the fork 3 is made greater than the running length of the slide 2, thereby increasing the maximum elongation of the fork 3, and the sliding of the fork 3 is achieved by sliding the rotating shaft 301 along the length direction of the slide 201. If the second horizontal running track is deformed downward, it must be caused by the bending deformation of the rotating shaft 301 or the deformation of the hole where the slide 201 and the rotating shaft 301 are plugged. The rotating shaft 301 is cylindrical and is in line contact with the slide 201. The rotating shaft 301 located inside the slide 201 is 01 is always located inside the slide 201. When the shaft 301 is deformed, radial deformation must occur at the two ends outside the slide 201. The deformation at the hole where the slide 201 and the shaft 301 are plugged will not affect the shape of the shaft 301 inside the slide 201. Therefore, the shaft 301 can still slide along the length direction of the slide 201, and the shaft 301 will not get stuck, so that the fork 3 will not get stuck, and the fork 3 can still achieve an increase in the maximum elongation.

[0041] It can be seen that the present invention utilizes the linkage cooperation between the linkage gear set and the toothed plate 7 and the transmission member, so that when the slide seat 2 slides, it can not only drive the fork 3 to move synchronously, but also drive the fork 3 and the slide seat 2 to slide relative to each other, so as to increase the elongation of the fork 3, and utilizes the sliding connection between the rotating shaft 301 rotatably installed at one end of the fork 3 and the slideway 201 provided on the slide seat 2 to realize the relative sliding between the fork 3 and the slide seat 2. If the second horizontal running track is deformed downward, it must be caused by the bending deformation of the rotating shaft 301 or the deformation of the hole where the slideway 201 and the rotating shaft 301 are plugged. The rotating shaft 301 is cylindrical, and there is a line contact between it and the slideway 201, and the rotating shaft 301 inside the slideway 201 is located. The shaft 301 is always located inside the slideway 201. When the shaft 301 is deformed, the two ends located outside the slideway 201 must be radially deformed. The deformation at the hole where the slideway 201 and the shaft 301 are plugged will not affect the shape of the shaft 301 located inside the slideway 201. Therefore, the shaft 301 can still slide along the length direction of the slideway 201, and the shaft 301 will not get stuck, so that the fork 3 will not get stuck. Therefore, the present invention can still achieve the addition of a fork horizontal running track to increase the maximum extension of the fork. Even if the added horizontal running track is deformed downward, it will not cause the horizontal running track to get stuck, which can effectively solve the shortcomings of the prior art.

[0042] At the same time, in the present invention, since only one end of the fork 3 is connected to the slide 2 by the rotating shaft 301, the end of the fork 3 away from the rotating shaft 301 can move up and down, so that when the fork 3 is deformed downward after a long period of load, the fork 3 can rotate freely when the fork 3 is recovered, and the fork 3 can still be completely recovered, and there will be no jamming between the fork 3 and the slide 2. It can be seen that in the present invention, whether the second horizontal running track is deformed downward or the fork 3 is deformed downward, it will not cause the fork 3 to get stuck.

[0043] Furthermore, the power input end of the transmission member is meshed with the linkage gear set, and the power output end of the transmission member is elastically slidably plugged with the fork 3 so that the power output end of the transmission member can pull the fork 3 to slide, and at the same time, one end of the fork 3 away from the rotating shaft 301 is elastically tilted, thereby reducing the sliding resistance of the fork 3 in the no-load state. When the fork 3 lifts the goods, the fork 3 is pressed down based on the gravity of the goods to elastically rotate to buffer the goods, and at the same time, the power output end of the linkage member protrudes from the fork 3 to prevent the goods from sliding down. Specifically, the transmission member has a power input end and a power output end. The power input end of the transmission member is meshed with the linkage gear set so that when the linkage gear set rotates, the transmission member is driven to move. The transmission member transmits power to its power output end. Since the power output end of the transmission member is plugged into the fork 3 up and down, the power output end of the transmission member drives the fork 3 to move. This is one of the functions of the power output end of the transmission member. Furthermore, since the fork 3 is elastically plugged into the power output end of the transmission member, the end of the fork 3 away from the rotating shaft 301 is elastically tilted, so that when the fork 3 lifts the goods, the fork 3 can be pressed down based on the gravity of the goods to elastically rotate around the rotating shaft 301. At this time, the power output end of the transmission member plays a role in buffering the goods. The cargo fork 3 is preferably positioned on the upper side of the fork 3, and the cargo is preferably positioned on the lower side of the fork 3. The cargo fork 3 is preferably positioned on the upper side of the fork 3, and the cargo is preferably positioned on the lower side of the fork 3.

[0044] In this embodiment, when the amount of downward deformation of the second horizontal running track increases, the length of the power output end of the transmission member protruding from the fork 3 increases when the fork 3 is driven to lift the goods, so as to judge the deformation degree of the second horizontal running track. Specifically, when the fork 3 supports the goods, the power output end of the transmission member will protrude from the top of the fork 3, and when the second horizontal running track deforms downward, after the fork 3 supports the goods, the fork 3 rotates downward to the lowest point, and the length of the power output end of the transmission member protruding from the top of the fork 3 will increase. By observing the increase in the length of the power output end of the transmission member protruding from the top of the fork 3, it can be judged whether the second horizontal running track has deformed downward. A marking line can also be marked on the power output end of the transmission member. When the second horizontal running track has not deformed, the marking line does not protrude from the top of the fork 3 when the goods are placed on the fork 3. When the downward deformation of the second horizontal running track causes the marking line to protrude from the top of the fork 3 when the goods are placed on the fork 3, it means that the deformation degree of the second horizontal running track is large, and the second horizontal running track can be replaced reliably to ensure the safety of cargo transportation. Similarly, when the fork 3 is deformed downward, it is still possible to determine whether the fork 3 is deformed downward by the length of the power output end of the transmission member protruding from the top of the fork 3, which is not described in detail. It can be seen that the power output end of the transmission member also plays a role in detecting whether the second horizontal running track and the fork 3 are deformed downward.

[0045] In this embodiment, when the fork 3 lifts the goods, the inner top surface of the fork 3 abuts against the top surface of the slide 2, thereby relieving the squeezing force on the rotating shaft 301 and the squeezing force on the hole where the slide 201 and the rotating shaft 301 are inserted, thereby reducing the probability of deformation of the second horizontal running track and improving the service life of the stacker.

[0046] In this embodiment, the driving member includes a first motor 12 and a driving gear 13 coaxially fixedly mounted on the output shaft of the first motor 12. The first motor 12 is a reducing motor or a servo motor or a stepping motor, etc., wherein the first motor 12 is fixedly mounted on the cargo platform 11, and a transmission tooth 202 meshing with the driving gear 13 is provided at the bottom of the slide 2. The first motor 12 drives the driving gear 13 to rotate forward and reverse. Based on the meshing of the driving gear 13 and the transmission tooth 202, the driving gear 13 drives the slide 2 to slide back and forth along the length direction of the base 1 when it rotates. Specifically, the base 1 is located directly below the center line of the slide 2, and a group of transmission teeth 202 are provided on both the left and right sides of the bottom of the slide 2. Two driving gears 13 are fixedly mounted on each first motor 12, and the two driving gears 13 mesh with the two groups of transmission teeth 202 at the bottom of the slide 2 one by one, thereby improving the force balance of the slide 2.

[0047] The interlocking gear set includes a main gear 8 rotatably mounted on the slide 2, the main gear 8 is located above the tooth plate 7 and meshes with the tooth plate 7 so that the slide 2 drives the main gear 8 to rotate, and the power input end of the transmission member is located above the main gear 8 and meshes with the main gear 8 so that the main gear 8 drives the transmission member to slide when the main gear 8 rotates. Specifically, when the driving member drives the slide 2 to slide, since the tooth plate 7 is stationary, the main gear 8 is driven to rotate, the rotation of the main gear 8 drives the transmission member to slide, and the sliding of the transmission member pulls the fork 3 to slide, so that the fork 3 and the slide 2 slide relative to each other, and the fork 3 slides synchronously with the slide 2, so the sliding length of the fork 3 is greater than the sliding length of the slide 2, thereby increasing the maximum elongation of the fork 3.

[0048] In order to further increase the maximum elongation of the fork 3, in this embodiment, the linkage gear set also includes a linkage gear 9 coaxially fixedly connected to the main gear 8. There are multiple linkage gear sets and they are arrayed along the length direction of the slide 2. The multiple linkage gears 9 arrayed along the length of the slide 2 are connected by a chain (not shown in the figure). Specifically, as the slide 2 continues to slide, the main gear 8 located in front of the slide gradually separates from the toothed plate 7 but does not separate from the power input end of the transmission member, and at the same time, the main gear 8 located behind the slide gradually separates from the power input end of the transmission member but does not separate from the toothed plate 7. Therefore, a connecting gear 9 is coaxially fixedly connected to each main gear 8, and multiple connecting gears 9 are linked by a chain, so that as long as one of the main gears 8 is engaged with the toothed plate 7, it can drive the corresponding connecting gear 9 to rotate. After the corresponding connecting gear 9 rotates, it can drive multiple connecting gears 9 to rotate synchronously through the chain. The rotation of multiple connecting gears 9 drives multiple main gears 8 to rotate synchronously. The rotation of multiple main gears 8 drives the power input end of the transmission member to move, and finally drives the fork 3 to continue to slide, thereby further improving the maximum elongation of the fork 3.

[0049] In this embodiment, the transmission member includes a sliding plate 4 that is slidably inserted along the length direction of the slide seat 2 and a pull rod 5 that is fixedly connected to the sliding plate 4. The bottom of the sliding plate 4 is provided with meshing teeth 401 that mesh with the main gear 8. The pull rod 5 is slidably inserted with the fork 3. The pull rod 5 is provided with a compression spring 501 that elastically abuts against the fork 3. The pull rod 5 is arc-shaped and the center of the arc is located on the axis line of the rotating shaft 301, so that the fork 3 can rotate smoothly around the rotating shaft 301 without being blocked by the pull rod 5. The meshing teeth 401 are the power input end of the transmission member, and the pull rod 5 is the power output end of the transmission member. Specifically, a side slide groove 204 is opened on the left and right sides of the slide seat 2, the number of sliding plates 4 is two and they are slidably inserted in a one-to-one correspondence with the two side slide grooves 204, and a pull rod 5 is fixedly installed on each sliding plate 4 to improve the stability when the pull rod 5 pulls the fork 3. The linkage gear group is divided into two groups and corresponds to the two sliding plates 4 one-to-one. The number of tooth plates 7 is also two, and the two tooth plates 7 correspond to the two groups of linkage gear groups one-to-one, so as to improve the force balance of the slide seat 2.

[0050] A through hole 302 is provided on the fork 3 for the pull rod 5 to be inserted. The through hole 302 includes an upper receiving hole and a lower guide hole which are connected up and down. The diameter of the upper receiving hole is larger than the diameter of the lower guide hole. The pull rod 5 includes a rod body and a limiting cap which are fixedly connected. In the initial state, the limiting cap is located in the upper receiving hole and abuts against the top of the lower guide hole to limit the fork 3 and prevent the fork 3 from being separated from the pull rod 5. The compression spring 501 is always in a compressed state to prevent the fork 3 from shaking in the initial state.

[0051] In this embodiment, a roller 6 is rotatably arranged on the slide 2, and the top of the roller 6 is at the same height as the top of the slide 2 so that when the inner top surface of the fork 3 abuts against the top surface of the slide 2, the friction between the fork 3 and the slide 2 is reduced. Specifically, an arc groove for accommodating the roller 6 is provided on the slide 2, and a plug-in ring 203 is fixedly installed in the arc groove. The shaft of the roller 6 rotates through the plug-in ring 203 so that the roller 6 rotates and is located in the arc groove. The number of the roller 6 is one or more, thereby greatly reducing the sliding friction of the fork 3.
