Description

Technical Field

[0001] This invention relates to the field of cotton harvesting equipment technology, and in particular, to a material storage device. Furthermore, this invention also relates to a box-type cotton harvester including the aforementioned material storage device. Background Technology

[0002] With social development and technological progress, agricultural products such as cotton are usually harvested using agricultural machinery and equipment to reduce the labor intensity of cotton farmers, reduce crop losses and waste, and bring significant economic benefits to agricultural production.

[0003] Currently, cotton harvesting equipment mainly includes box-type cotton harvesters and baler-type cotton harvesters. Among them, box-type cotton harvesters are more flexible in design and use, and can adapt to cotton fields with different planting patterns and row spacings. They are more advantageous in some specific regions or small cotton fields. Moreover, the initial purchase cost of box-type cotton harvesters is relatively low, so they have been widely used.

[0004] Box-type cotton harvesters collect harvested cotton using cotton boxes as storage devices. Therefore, the larger the capacity of the cotton box, the higher the operating efficiency of the box-type cotton harvester. However, in order to make reasonable layout of each component and ensure passage during transportation, the volume of the cotton box on the box-type cotton harvester is often relatively fixed. Therefore, existing cotton boxes are equipped with devices such as compaction augers to help distribute the cotton evenly in the cotton box and to assist in compacting the fluffy cotton. This can increase the capacity of the cotton box with a relatively fixed volume. For example, Chinese invention patent CN109392449A discloses a cotton harvester, which specifically has a stirring and compaction mechanism set below the cotton inlet of the inner box, including three stirrings evenly distributed in the cotton box and a stirring motor that drives each stirring. The diameter of the stirring blades gradually decreases from one end near the cotton inlet to the other end, resembling a cone shape. When the agitator rotates, it presses the cotton downwards and simultaneously conveys some of it inwards. In the aforementioned "conical" structure, the blades at the end near the cotton inlet have a larger diameter, ensuring that the cotton entering from the inlet is conveyed as far inwards as possible, preventing excessive cotton accumulation near the inlet. Conversely, because the diameter of the agitator blades decreases towards the inlet, the horizontal conveying capacity of the cotton decreases further inwards, preventing excessive cotton from being squeezed to the inner part of the cotton box. This ensures that the cotton is distributed as evenly as possible within the cotton box, maximizing the cotton loading capacity and improving overall cotton harvesting efficiency.

[0005] However, in the aforementioned cotton harvester, unloading is achieved through an automatic cotton unloading mechanism. Specifically, a tilting door is rotatably connected to the bottom of the cotton box on one side. The tilting door is opened and closed by hydraulic cylinders connected to the two sides of the cotton box. A chain rake assembly is located on the inner side of the tilting door and the bottom surface of the cotton box. The chain rake assembly includes a drive shaft, a driven shaft, multiple sprockets on the drive shaft and driven shaft, multiple chains connecting the drive shaft and driven shaft via the sprockets, chain rakes on the chains, and a chain rake motor at one end of the drive shaft. During operation, the chain rake motor drives the drive shaft to rotate, which in turn drives the driven shaft to rotate via the sprockets and chains. Simultaneously, the chains drive the chain rakes to move, gradually rakeing the cotton out from the bottom of the cotton box. While the above structure enables existing cotton harvesters to store large amounts of material and unload automatically, it results in an excessive number of drive components inside the cotton box, making the drive system very complex. This leads to low reliability in actual operation, and the drive system is prone to failure. Moreover, once a failure occurs, troubleshooting and maintenance are difficult, which greatly affects the operating efficiency of the cotton harvester. Summary of the Invention

[0006] This invention provides a material storage device and a box-type cotton harvester to solve the technical problems of existing cotton harvesters, which, in order to achieve large-capacity material storage and automatic unloading, result in a large number of internal drive structures in the cotton box of the cotton harvester, a complex drive system, and are prone to failure, making troubleshooting and maintenance difficult.

[0007] According to one aspect of the present invention, a material storage device is provided, comprising a bottom support, a housing, a pressing assembly, a driving assembly, a first linkage assembly, and a second linkage assembly. The housing includes a shell, a cover plate, and a door. The shell is rotatably connected to the bottom support. The shell has a horizontal discharge port arranged in a horizontal direction and a vertical discharge port arranged in a vertical direction and communicating with the horizontal discharge port. The cover plate is rotatably connected to the shell and is used to open or close the horizontal discharge port. The door is rotatably connected to the shell and is used to open or close the vertical discharge port. The pressing assembly is arranged in the shell and is used to compact the material. The driving assembly is connected to the shell... The body and the bottom support are connected and used to drive the housing to rotate relative to the bottom support, so that the vertical discharge port and the horizontal discharge port are tilted downwards or reset to the initial state, thereby tilting and unloading or resetting the storage. The first linkage component is connected to the cover plate and the bottom support respectively. The first linkage component is used to link the cover plate to open the horizontal discharge port when tilting and unloading, or to link the cover plate to close the horizontal discharge port when storing material horizontally. The second linkage component is connected to the housing, the valve and the bottom support respectively. The second linkage component is used to link the valve to open the vertical discharge port when tilting and unloading, or to link the valve to close the vertical discharge port when storing material horizontally.

[0008] As a further improvement to the above technical solution:

[0009] Furthermore, the shell includes a bottom plate, a first wall formed by the upward and outward inclined extension of the edge of the bottom plate in the width direction, a second wall formed by the upward extension of the first wall, and a third wall formed by the upward extension of the edge of the bottom plate in the length direction. The bottom plate, the first wall, the second wall, and the third wall enclose a storage cavity. The first wall is rotatably connected to the upper end of the bottom support. The top of the second wall and the second wall enclose a horizontal discharge port. A vertical discharge port is opened on the side of the second wall. The first wall is rotatably connected to the upper end of the bottom support. The upper end of the first wall near the bottom support is rotatably connected to a valve. The upper end of the third wall away from the bottom support is rotatably connected to a cover plate.

[0010] Furthermore, the first linkage assembly includes a first linkage frame hinged to the bottom support and a second linkage frame hinged to the first linkage frame and fixedly connected to the cover plate. The first linkage frame and the second linkage frame are arranged in a downward bending shape, and the hinge point of the first linkage frame and the bottom support is located below the hinge point of the first wall and the bottom support.

[0011] Furthermore, a feed inlet 1 is provided on the side of the third wall, and a feed inlet 2 is provided on the second linkage frame for communicating with the feed inlet 1.

[0012] Furthermore, the second linkage assembly includes a telescopic assembly with an adjustable length that is hinged to the bottom frame, a first connecting rod that is hinged to the telescopic assembly and the third wall respectively, and a second connecting rod that is hinged to the free end of the valve and the telescopic assembly respectively.

[0013] Furthermore, the telescopic assembly includes a first telescopic rod hinged to the first connecting rod and the second connecting rod respectively, a second telescopic rod hinged to the bottom bracket, and an adjusting sleeve threaded to the first telescopic rod and the second telescopic rod respectively for rotating to move the first telescopic rod and the second telescopic rod closer to each other or further apart. The threads on the first telescopic rod and the second telescopic rod have opposite directions of rotation.

[0014] Furthermore, the pressing assembly includes a pressing fixing seat arranged on the third wall, a pressing driving component arranged on the pressing fixing seat, a linkage rod hinged to the driving end of the pressing driving component, a limiting rod fixedly arranged on the third wall, and a pressing plate connected to the linkage rod and the limiting rod respectively for rotating around the limiting rod to compact the material.

[0015] Furthermore, the second linkage component includes a tension spring whose first end is connected to the valve, and an adjusting member disposed on the third wall and connected to the second end of the tension spring for adjusting the elongation of the tension spring relative to the third wall.

[0016] Furthermore, the adjusting component includes a fixed plate fixedly arranged on the third wall, an adjusting bolt movably passing through the fixed plate, an adjusting plate fixedly connected to the first end of the adjusting bolt and connected to the second end of the tension spring, and an adjusting nut threadedly connected to the second end of the adjusting bolt.

[0017] According to another aspect of the present invention, a box-type cotton harvester is also provided, which includes the above-described material storage device.

[0018] The present invention has the following beneficial effects:

[0019] The material storage device of this invention comprises a housing mounted on a bottom support, which holds material through a shell. The shell is then sealed with a cover plate and a valve to prevent spillage. A pressing assembly is installed inside the shell to compact the material upon entry into the sealed cavity, increasing the material capacity within the same volume and thus improving operational efficiency. Initially, the horizontal discharge port is horizontally positioned, and the vertical discharge port is vertically positioned. Upon reaching the discharge point, a drive assembly rotates the shell relative to the bottom support, tilting the shell relative to the support. This causes the horizontal and vertical discharge ports to tilt downwards. At this point, a first linkage assembly opens the horizontal discharge port by connecting the cover plate, and a second linkage assembly opens the vertical discharge port by connecting the valve. Under gravity, the horizontal and vertical discharge ports work together to achieve efficient tilting and unloading. After unloading is complete... Afterwards, the drive assembly drives the housing to rotate in the opposite direction to the bottom support and reset. At this time, the vertical and horizontal discharge ports are reset to their initial state, and the first linkage assembly links the cover plate to close the horizontal discharge port, while the second linkage assembly links the valve to close the vertical discharge port, allowing the box to store materials. This solution achieves large-capacity material storage and automatic unloading through the coordinated operation of the bottom support, box, pressing assembly, drive assembly, first linkage assembly, and second linkage assembly. Under the action of two drive components, the pressing assembly and the drive assembly, located inside and outside the box respectively, it achieves large-capacity material storage and automatic unloading. Compared with the existing technology, the box only has one drive component, the pressing assembly, which simplifies the internal structure and greatly improves the reliability of the material storage device, thereby reducing the probability of failure. Furthermore, troubleshooting and maintenance are simple after a failure occurs, which helps to improve the efficiency of the box-type cotton harvester using this material storage device. It is highly practical and suitable for widespread promotion and application.

[0020] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

Detailed Implementation

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0031] Example 1

[0032] like Figures 1-5As shown, the storage device of this embodiment includes a bottom support 100, a housing 200, a pressing assembly 300, a drive assembly 400, a first linkage assembly 500, and a second linkage assembly 600. The housing 200 includes a shell 210, a cover plate 220, and a door 230. The shell 210 is rotatably connected to the bottom support 100. The shell 210 has a horizontal discharge port arranged in a horizontal direction and a vertical discharge port arranged in a vertical direction and communicating with the horizontal discharge port. The cover plate 220 is rotatably connected to the shell 210 and is used to open or close the horizontal discharge port. The door 230 is rotatably connected to the shell 210 and is used to open or close the vertical discharge port. The pressing assembly 300 is arranged in the shell 210 and is used to compact the material. The drive assembly 400 is respectively connected to the bottom support 100, the bottom support 100, the bottom support 2 ... The housing 210 and the bottom support 100 are connected and used to drive the housing 210 to rotate relative to the bottom support 100, so that the vertical discharge port and the horizontal discharge port are tilted downwards or reset to their initial state, thereby performing tilting discharge or resetting storage. The first linkage component 500 is connected to the cover plate 220 and the bottom support 100 respectively. The first linkage component 500 is used to link the cover plate 220 to open the horizontal discharge port when tilting discharge, or to link the cover plate 220 to close the horizontal discharge port when storing material horizontally. The second linkage component 600 is connected to the housing 210, the valve 230 and the bottom support 100 respectively. The second linkage component 600 is used to link the valve 230 to open the vertical discharge port when tilting discharge, or to link the valve 230 to close the vertical discharge port when storing material horizontally.

[0033] like Figures 1-5As shown, specifically, the storage device of the present invention has a box 200 mounted on a bottom support 100. The box 200 contains materials through a housing 210, and the housing 210 is then closed by a cover plate 220 and a door 230 to prevent materials from spilling out. A pressing assembly 300 is installed inside the housing 210 to compact the materials after they enter the closed cavity, thereby increasing the material capacity within the same volume and improving operational efficiency. In the initial state, the horizontal discharge port is horizontally arranged. The vertical discharge port is vertically arranged. After moving to the discharge point, the drive assembly 400 drives the housing 210 to rotate relative to the bottom support 100, so that the housing 210 is tilted relative to the bottom support 100, thereby tilting the horizontal and vertical discharge ports downwards. At this time, the first linkage assembly 500 links the cover plate 220 to open the horizontal discharge port, and the second linkage assembly 600 links the valve 230 to open the vertical discharge port. Under the action of gravity, the horizontal and vertical discharge ports work together to achieve efficient tilting discharge. After completion, the drive assembly drives the housing 210 to rotate in the opposite direction to the bottom support 100 and reset. At this time, the vertical and horizontal discharge ports are reset to their initial states, and the first linkage assembly 500 links the cover plate 220 to close the horizontal discharge port, while the second linkage assembly 600 links the valve 230 to close the vertical discharge port, allowing the housing 200 to store materials. This solution utilizes the coordinated operation of the bottom support 100, housing 200, pressing assembly 300, drive assembly 400, first linkage assembly 500, and second linkage assembly 600 to achieve material storage. The material storage device achieves large-capacity material storage and automatic unloading through the two drive components, namely the pressing component 300 and the drive component 400, located inside and outside the housing 200. Compared with the prior art, the housing 200 only has one drive component, the pressing component 300, which simplifies the internal structure and greatly improves the reliability of the material storage device, thereby reducing the probability of failure. In the event of a failure, troubleshooting and maintenance are simple, which helps to improve the efficiency of the box-type cotton harvester using this material storage device. It is highly practical and suitable for widespread promotion and application.

[0034] like Figure 2As shown, in this embodiment, the housing 210 includes a base plate 211, a first wall 212 formed by the upward and outward inclined extension of the edge of the base plate 211 in the width direction, a second wall 213 formed by the upward extension of the first wall 212, and a third wall 214 formed by the upward extension of the edge of the base plate 211 in the length direction. The base plate 211, the first wall 212, the second wall 213, and the third wall 214 enclose a storage cavity. The first wall 212 is rotatably connected to the upper end of the bottom support 100. The top of the second wall 213 encloses a horizontal discharge port. A vertical discharge port is opened on the side of the second wall 213. The first wall 212 is rotatably connected to the upper end of the bottom support 100. The upper end of the first wall 212 near the bottom support 100 is rotatably connected to a valve 230. The upper end of the third wall 214 away from the bottom support 100 is rotatably connected to a cover plate 220. Specifically, the volume of the storage cavity mainly depends on the width and length of the bottom plate 211, as well as the height of the first wall 212, the second wall 213, and the third wall 214. The first wall 212, which extends upward and outward, increases the volume in the width direction to a certain extent. When the shell 210 is in a tilted state, it discharges material through the inclined surface of the second wall 213 under the action of gravity. The volume can be further increased by the second wall 213. The second wall 213 is arranged in a vertical direction, which is conducive to improving the stability of the shell 210 structure and the passability of the box-type cotton harvester using this storage device. Furthermore, by using the vertical discharge port on the second wall 213 in conjunction with the horizontal discharge port for discharge, material accumulation on the second wall 213 is prevented, thus achieving efficient discharge.

[0035] It should be understood that "passability" refers to the ability of a box-type cotton harvester to pass through structures such as width-limited bins during its movement.

[0036] like Figure 2As shown, in this embodiment, the first linkage component 500 includes a first linkage frame 510 hinged to the bottom support 100 and a second linkage frame 520 hinged to the first linkage frame 510 and fixedly connected to the cover plate 220. The hinge point between the first linkage frame 510 and the bottom support 100 is located below the hinge point between the first wall 212 and the bottom support 100. Specifically, since the hinge point of the first linkage frame 510 and the bottom support 100 is located below the hinge point of the first wall 212 and the bottom support 100, and the first linkage frame 510 and the second linkage frame 520 are arranged in a downward bending shape, when the drive assembly 400 drives the first wall 212 to rotate relative to the bottom support 100, the distance between the connection point between the second linkage frame 520 and the cover plate 220 and the hinge point of the first linkage frame 510 and the bottom support 100 increases, and the first linkage frame 510 and the second linkage frame 520 unfold outward to drive the cover plate 220 to move outward, so that when the housing 210 is in a tilted state, the linkage cover plate 220 opens the horizontal unloading port.

[0037] In this embodiment, a first feed inlet is provided on the side of the third wall 214, and a second feed inlet is provided on the second linkage frame 520 for communicating with the first feed inlet. Specifically, in the initial state, the first feed inlet and the second feed inlet are connected, and the harvested material is stored in the storage cavity through the second feed inlet and the first feed inlet in sequence.

[0038] like Figure 3As shown, in this embodiment, the second linkage component 600 includes a telescopic assembly 610 with an adjustable length and hinged to the bottom frame, a first connecting rod 620 hinged to the telescopic assembly 610 and the third wall 214 respectively, and a second connecting rod 630 hinged to the free end of the valve 230 and the telescopic assembly 610 respectively. Specifically, in the initial state, under the action of gravity, the telescopic assembly 610, the first connecting rod 620, and the second connecting rod 630 move downwards, and the included angle between the first connecting rod 620 and the second connecting rod 630 decreases, thereby pulling the valve 230 to rotate towards the housing 210, thus closing the vertical discharge port on the housing 210; when the housing 210 is in an overturned state, with the vertical discharge port tilted downwards, under the action of gravity, the telescopic assembly 610, the first connecting rod 620, and the second connecting rod 630 move downwards, and the included angle between the first connecting rod 620 and the second connecting rod 630 increases, causing the free end of the valve 230 to rotate away from the second wall 213, thereby opening the housing 210. The vertical unloading port is designed so that the opening and closing angle of the valve 230 relative to the second wall 213 is appropriate. In the initial state, the valve 230 can automatically close the vertical unloading port under the action of the second linkage component 600. When the housing 210 is tilted, the valve 230 automatically opens the vertical unloading port under the action of closing the second linkage component 600. At this time, the length of the telescopic assembly 610 is at its minimum. By increasing the length of the telescopic assembly 610, the opening and closing angle of the valve 230 relative to the second wall 213 during unloading can be increased to ensure that the crop is smoothly unloaded from the unloading port. Thus, the opening and closing angle of the valve 230 relative to the second wall 213 can be changed within a certain range according to the unloading requirements to ensure unloading efficiency. It should be understood that if the lengths of the connecting rods in the second linkage assembly 600 are all fixed, the components may interfere with each other during assembly, making assembly difficult. However, this application uses the length-adjustable telescopic assembly 610 to adjust the length, which effectively avoids interference between the components during the assembly of the second linkage assembly 600, thereby greatly reducing the assembly difficulty of the second linkage assembly 600.

[0039] like Figure 5As shown, in this embodiment, the telescopic assembly 610 includes a first telescopic rod 611 hinged to the first connecting rod 620 and the second connecting rod 630 respectively, a second telescopic rod 612 hinged to the bottom bracket 100, and an adjusting sleeve 613 threadedly connected to the first telescopic rod 611 and the second telescopic rod 612 respectively, for rotating the first telescopic rod 611 and the second telescopic rod 612 to move closer to each other or further away from each other. The threads on the first telescopic rod 611 and the second telescopic rod 612 have opposite directions of rotation. Specifically, since the first telescopic rod 611 cannot rotate due to interference from the bottom frame, and the second telescopic rod 612 cannot rotate due to interference from the first connecting rod 620 and the second connecting rod 630, and since the threads on the first telescopic rod 611 and the second telescopic rod 612 rotate in opposite directions, by rotating the adjusting sleeve 613, the first telescopic rod 611 and the second telescopic rod 612 are brought closer to each other, thereby reducing the length of the telescopic assembly 610, or the first telescopic rod 611 and the second telescopic rod 612 are moved away from each other, thereby increasing the length of the telescopic assembly 610, thereby adjusting the opening and closing angle of the valve 230 relative to the second wall 213.

[0040] like Figure 5 As shown, in this embodiment, a positioning nut 614 is threaded onto the first telescopic rod 611 to abut against the adjusting sleeve 613, preventing the first telescopic rod 611 and the second telescopic rod 612 from approaching each other. Specifically, when the positioning nut 614 is threaded onto the first telescopic rod 611 and abuts against the adjusting sleeve 613, the adjusting sleeve 613 cannot drive the first telescopic rod 611 and the second telescopic rod 612 to approach each other and reduce the length of the telescopic assembly 610 when it rotates, thus fixing the minimum length of the telescopic assembly 610. This allows the opening and closing angle of the valve 230 relative to the second wall 213 to be fixed according to the unloading requirements. In other words, by ensuring that the opening and closing angle of the valve 230 relative to the second wall 213 meets the unloading requirements when the telescopic assembly 610 is at its minimum length.

[0041] like Figure 5 As shown, in this embodiment, the second telescopic rod 612 is threadedly connected to a positioning nut 615 for abutting against the adjusting sleeve 613 to prevent the first telescopic rod 611 and the second telescopic rod 612 from approaching each other. Specifically, when the positioning nut 615 is threadedly connected to the second telescopic rod 612 and abuts against the adjusting sleeve 613, the adjusting sleeve 613 cannot drive the first telescopic rod 611 and the second telescopic rod 612 to approach each other and reduce the length of the telescopic assembly 610 when it rotates, thereby fixing the minimum length of the telescopic assembly 610. This allows the opening and closing angle of the valve 230 relative to the second wall 213 to be fixed according to the unloading requirements. In other words, by ensuring that the opening and closing angle of the valve 230 relative to the second wall 213 meets the unloading requirements when the telescopic assembly 610 is at its minimum length, the telescopic assembly 610 is at its minimum length.

[0042] like Figure 3 and Figure 5 As shown, in this embodiment, the pressing assembly 300 includes a pressing fixing seat 310 disposed on the third wall 214, a pressing driving member 320 disposed on the pressing fixing seat 310, a linkage rod 330 hinged to the driving end of the pressing driving member 320, a limiting rod 340 fixedly disposed on the third wall 214, and a pressing plate 350 connected to the linkage rod 330 and the limiting rod 340 respectively for rotating around the limiting rod 340 to compact the material. Specifically, the pressing driving member 320 is installed on the pressing fixing seat 310. The driving end of the pressing driving member 320 extends and retracts to drive the linkage rod 330 to pull the pressing plate 350 to rotate around the limiting rod 340, thereby compacting the material or reversing to reset, thus repeating this cycle to increase the capacity of the box 200. Optionally, the pressing driving member 320 is one of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod.

[0043] In this embodiment, the drive assembly 400 is one of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod.

[0044] Example 2

[0045] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the second linkage component 600 includes a tension spring 640 whose first end is connected to the valve 230 and an adjusting member arranged on the third wall 214 and connected to the second end of the tension spring 640 for adjusting the elongation of the tension spring 640 relative to the third wall 214. Specifically, when the housing 210 tilts to unload material, under the combined action of the gravity of the valve 230 and the gravity of the material, the valve 230 flips downward to open the vertical unloading port. At this time, the tension spring 640 is simultaneously stretched to produce elastic deformation, thereby applying a restoring elastic force to the valve 230. The opening and closing angle of the valve 230 can be steplessly changed according to the amount of material unloaded, improving unloading efficiency. After unloading is completed, the tension spring 640 pulls the valve 230 to close the vertical unloading port. The elongation of the tension spring 640 relative to the third wall 214 can be adjusted by adjusting the adjustment component to reduce or increase the gravity required to open the valve 230, thereby further adjusting the opening and closing angle of the valve 230. The specific adjustment amount can be adaptively adjusted according to the unloading requirements.

[0046] like Figure 6As shown, in this embodiment, the adjusting component includes a fixed plate 651 fixedly mounted on the third wall 214, an adjusting bolt 652 movably passing through the fixed plate 651, an adjusting plate 653 fixedly connected to the first end of the adjusting bolt 652 and connected to the second end of the tension spring 640, and an adjusting nut 654 threadedly connected to the second end of the adjusting bolt 652. Specifically, the adjusting bolt 652 is installed on the fixed plate 651, the adjusting plate 653 is connected to the adjusting bolt 652, the adjusting plate 653 is connected to the second end of the tension spring 640, and finally the adjusting nut 654 is threadedly connected to the second end of the adjusting bolt 652 to complete the assembly of the adjusting component. During the assembly process, by rotating the adjusting nut 654, the relative movement between the adjusting nut 654 and the adjusting bolt 652 can be achieved, thereby reducing or increasing the gravity required for the valve 230 to open.

[0047] like Figure 6 As shown, in this embodiment, the valve 230 is provided with a first hook connected to the first end of the tension spring 640, and the adjusting plate 653 is provided with a second hook connected to the second end of the tension spring 640. The first hook and the second hook are arranged opposite to each other.
