Description

Technical Field

[0001] This invention relates to the field of energy storage power supply technology, specifically to a rechargeable energy storage power supply with a removable battery. Background Technology

[0002] Energy storage power supplies are devices that can convert electrical energy into other forms of energy for storage and convert it back into electrical energy when needed. They can achieve electrical energy storage through technologies such as battery energy storage, supercapacitor energy storage, and mechanical energy storage.

[0003] In existing rechargeable energy storage power supplies, the internal batteries are mostly fixed by clips or bolts. When the battery malfunctions and needs to be replaced or its capacity needs to be increased, multiple bolts must be loosened to remove the cover from the casing before the battery can be disassembled. The disassembly and installation process is very cumbersome and causes great inconvenience to users. In addition, some energy storage power supplies with replaceable batteries have unstable battery fixation, which can easily cause shaking during movement or use, resulting in loose electrode connections and affecting the normal operation of the power supply. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rechargeable energy storage power source with a detachable battery.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention provides a removable rechargeable energy storage power source, comprising a housing and a battery body disposed within the housing, and further comprising: Limiting frame: The limiting frame is fixedly installed on the housing and is used to guide and limit the battery body. Movable plates are slidably installed on both sides of the housing. Each movable plate is provided with a clamping component for clamping and fixing the battery body. The clamping component includes a clamping unit provided on the housing and a limiting unit provided on the movable plate. Cover plate: The cover plate is provided with a quick-release assembly and is detachably connected to the limiting frame through the quick-release assembly. The limiting frame is provided with slots around its perimeter for use with the quick-release assembly. A perforated plate; the perforated plate is fixedly installed inside the housing and divides the space inside the housing into a battery housing cavity and a ventilation cavity. Several heat dissipation holes are provided on both sides of the housing.

[0006] As a preferred embodiment of the present invention, the clamping unit includes multiple pressure plates fixedly mounted on a movable plate. The pressure plates extend along the length of the housing. Multiple first springs are fixedly mounted between the movable plate and the bottom of the housing. An "M"-shaped track groove is formed on the movable plate. A pull rod is rotatably mounted on the perforated plate. A rotating wheel is rotatably mounted on one end of the pull rod. The rotating wheel is slidably disposed within the track groove. A rotating shaft is rotatably mounted on the movable plate. Threaded rods are threaded onto both ends of the rotating shaft. Clamping plates are threaded onto both threaded rods. A gear is fixedly mounted on the rotating shaft. A toothed plate that mates with the gear is fixedly mounted on the inner wall of the housing on the same side as the gear. A bending point for limiting the rotation wheel is provided in the middle of the track groove.

[0007] As a preferred embodiment of the present invention, the two threaded rods have opposite thread directions.

[0008] As a preferred embodiment of the present invention, the track groove is composed of a V-shaped part in the middle and inclined parts on both sides. The bending point at the upper end of the V-shaped part is staggered with the bending point at the lower end, so that the rotating wheel can move smoothly from the V-shaped part to the inclined part. The intersection of the V-shaped part and the inclined parts on both sides adopts a rounded transition.

[0009] As a preferred embodiment of the present invention, the limiting unit includes a plurality of hinge rods hinged above the moving plate, the limiting frame is provided with a sliding groove and a card plate is slidably installed in the sliding groove, and the top of the hinge rod is hinged to the card plate on the same side.

[0010] As a preferred embodiment of the present invention, the slide groove consists of a horizontal groove for sliding the card plate and a vertical groove for moving the hinge rod, wherein the width of the horizontal groove is greater than the width of the vertical groove.

[0011] As a preferred embodiment of the present invention, a telescopic rod is provided inside the first spring, and the two ends of the telescopic rod are fixedly connected to the moving plate and the bottom of the housing, respectively.

[0012] As a preferred embodiment of the present invention, the quick-release assembly includes a rotating shaft rotatably mounted on a cover plate, a rotating disk fixedly mounted at the bottom end of the rotating shaft, four connecting rods hinged to the rotating disk, insert plates slidably mounted on the four sides of the cover plate, each insert plate being hinged to a connecting rod on the same side, a torsion spring sleeved on the rotating shaft, the two ends of the torsion spring being fixedly connected to the rotating disk and the cover plate respectively, the insert plates cooperating with slots on the same side, the top end of the rotating shaft extending outside the cover plate and a knob fixedly mounted thereon, and a receiving groove for cooperating with the knob being provided on the cover plate.

[0013] As a preferred embodiment of the present invention, the insert plate is provided with a downward inclined surface, which is used in conjunction with the limiting frame.

[0014] As a preferred embodiment of the present invention, each of the insert plates is fixedly installed with a limiting part, and the cover plate is provided with a limiting groove for use with the limiting part.

[0015] The beneficial effects of this invention are: 1. This type of removable rechargeable energy storage power supply, through the setting of a clamping assembly, allows the battery body to be inserted. During this process, a pressure plate pushes a moving plate downward, compressing a first spring. As the moving plate moves downward, the gears and toothed plates work together to rotate the shaft and the threaded rods on both sides. This causes the clamping plates on both sides to move closer together and laterally clamp and fix the battery body. Once the clamping plates have fixed the battery, the gears and toothed plates disengage, preventing the shaft from rotating as the moving plate continues to move downward. Combined with the self-locking characteristic of the threaded rods, this ensures the stability of the battery body during subsequent use and prevents damage. Simultaneously, the pulling force of the pull rod on the moving plate and the elastic force of the first spring limit and fix the moving plate. Thus, the battery body can be clamped and fixed while being inserted into the battery housing cavity, and the moving plate can be limited at the same time. This facilitates the installation and removal of the battery body without the need for subsequent fixing and limiting operations. The operation is simple and convenient.

[0016] 2. This type of detachable rechargeable energy storage power supply, through the setting of a limiting unit, will pull the clamping plate through the hinge rod during the downward movement of the moving plate, so that the clamping plate gradually extends out of the slide groove. When the rotating wheel moves to the bend of the V-shaped part, the clamping plate moves to the top of the battery body, and clamps and limits the battery body in the vertical direction to prevent the battery body from moving in the vertical direction. In conjunction with the clamping plate, the battery body is clamped and fixed in multiple directions, further improving the stability of fixing the battery body.

[0017] 3. This type of removable rechargeable energy storage power supply features a clamping unit. When it is necessary to release the clamping of the battery body, pressing down on the battery body causes the rotating wheel to move upward within the V-shaped portion of the track groove. When the rotating wheel reaches the highest point of the track groove, the downward pressure resistance increases significantly. At this point, the pressure acting on the battery body is released, and the V-shaped portion releases its restriction on the rotating wheel. This allows the moving plate to smoothly reset under the elastic force of the first spring. The hinge rod then drives the clamping plate to move away from the battery body, preventing the clamping plate from interfering with the upward movement of the moving plate and the battery body. As the moving plate continues to reset upward, the toothed plate re-engages with the gear, causing the rotating shaft and threaded rod to reverse. This causes the two clamping plates to move away from each other and release the restriction on the battery body. Thus, simply pressing down on the battery body releases the restriction and allows the battery body to be removed from the battery housing cavity, facilitating the installation and removal of the battery body. The operation is simple and convenient.

[0018] 4. This type of removable rechargeable energy storage power supply features a quick-release assembly. Rotating the knob drives the rotating shaft and rotating disk to rotate, compressing the torsion spring. Simultaneously, the rotating disk moves the insert plate closer to the rotating disk via a connecting rod, then the cover plate closes onto the limiting frame. Releasing the knob allows the torsion spring to reset the rotating disk and insert plate, inserting the insert plate into the slot on the same side, thus locking the cover plate in place. Similarly, to remove the cover plate, rotating the knob again rotates the rotating disk, moving the insert plate out of the slot on the same side, releasing the lock between the cover plate and the limiting frame, allowing the cover plate to be quickly removed from the limiting frame for easy installation and removal of the battery body. The structure is simple and easy to use.

[0019] 5. This type of removable rechargeable energy storage power supply, by setting an inclined surface, allows the cover plate to be pressed down during installation of the cover plate and the limiting frame. When the inclined surface of the insert plate is squeezed by the limiting frame, it will move towards the rotating disk side and drive the rotating disk to rotate under the action of the connecting rod, compressing the torsion spring. When the slot and the insert plate are aligned, the pressure on the inclined surface of the insert plate disappears, and the insert plate returns to its original position under the action of the torsion spring's own elasticity, allowing the insert plate to be inserted into the slot on the same side, completing the locking connection of the cover plate. This further improves the convenience of installation and connection between the cover plate and the limiting frame. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1 to 9 As shown, the present invention provides a removable rechargeable energy storage power supply, including a housing 1 and a battery body disposed within the housing 1, and further comprising: Limiting frame 3: The limiting frame 3 is fixedly installed on the housing 1 and is used to guide and limit the battery body. Movable plates 4 are slidably installed on both sides of the housing 1. Each movable plate 4 is provided with a clamping component 5 for clamping and fixing the battery body. The clamping component 5 includes a clamping unit 51 provided on the housing 1 and a limiting unit 52 provided on the movable plate 4. Cover plate 6: The cover plate 6 is provided with a quick release component 7, and is detachably connected to the limiting frame 3 through the quick release component 7. The limiting frame 3 has slots 76 around its perimeter for use with the quick release component 7. The perforated plate 8 is fixedly installed inside the housing 1 and divides the space inside the housing 1 into a battery housing cavity and a ventilation cavity. Several heat dissipation holes 2 are provided on both sides of the housing 1.

[0024] Specifically, during use, the battery body is placed in the battery housing cavity under the guidance and limitation of the limiting frame 3. Then, the battery body is clamped and fixed by the clamping component 5. After fixing, the quick-release component 7 is used to quickly install the cover plate 6 and the limiting frame 3. The perforated plate 8 can separate the battery housing cavity from the ventilation cavity, ensuring air circulation between the battery housing cavity and the ventilation cavity, while preventing external dust and moisture from entering the battery housing cavity. The perforated plate 8 facilitates heat dissipation at the bottom of the battery body and accelerates the air circulation around the battery body, quickly dissipating the heat generated by the battery body during use. In actual use, a cooling fan can also be installed in the ventilation cavity to accelerate the air circulation in the ventilation cavity as needed.

[0025] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the clamping unit 51 includes multiple pressure plates 511 fixedly mounted on the movable plate 4. The pressure plates 511 extend along the length of the housing 1. Multiple first springs 512 are fixedly mounted between the movable plate 4 and the bottom of the housing 1. The movable plate 4 has an "M"-shaped track groove 513. A pull rod 514 is rotatably mounted on the perforated plate 8. A rotating wheel 515 is rotatably mounted on one end of the pull rod 514. The rotating wheel 515 is slidably disposed in the track groove 513. The movable plate 4 rotates... A rotating shaft 516 is installed, and threaded rods 517 are threaded on both ends of the rotating shaft 516. Clamping plates 518 are threaded on both threaded rods 517. A gear 519 is fixedly installed on the rotating shaft 516. A toothed plate 5110 that mates with the gear 519 is fixedly installed on the inner wall of the housing 1 on the same side of the gear 519. The threads of the two threaded rods 517 are in opposite directions. A bending point 5111 for limiting the rotation wheel 515 is provided in the middle of the track groove 513.

[0026] Furthermore, during the process of inserting the battery body into the battery housing cavity, the battery body pushes the moving plate 4 downward through the pressure plate 511 and compresses the first spring 512. During the downward movement of the moving plate 4, the gear 519 and the toothed plate 5110 come into contact and mesh. That is, when the moving plate 4 moves downward, the gear 519 and the toothed plate 5110 will drive the rotating shaft 516 and the threaded rods 517 on both sides to rotate. The two threaded rods 517 have opposite threads, so that the clamping plates 518 on both sides move closer to each other during the downward movement of the moving plate 4 and clamp and fix the battery body laterally. After the clamping plates 518 fix the battery, the gear 519 and the toothed plate 5110 disengage, so that when the moving plate 4 continues to move downward, the rotating shaft 516 will not rotate. Combined with the self-locking characteristic of the threaded rods 517, the stability of the battery body during subsequent use can be guaranteed, and damage to the battery body can be avoided during use. Simultaneously, as the moving plate 4 moves downward, the cooperation of the track groove 513, the pull rod 514, and the rotating wheel 515 causes the rotating wheel 515 to slide upward along the track groove 513. As the moving plate 4 moves downward, when the rotating wheel 515 reaches the highest point of the track groove 513, the moving plate 4 reaches its maximum downward position, and the downward pressure resistance increases significantly. At this point, the pressure acting on the battery body is released, and the first spring 512 pushes the moving plate 4 upward to reset a certain distance under its own elasticity. Since the gear 519 and the toothed plate 5110 have disengaged, the moving plate 4 will not drive the rotating shaft 516 to rotate when it moves upward, and the clamping plate 518 still maintains a stable clamping of the battery body. As the moving plate 4 moves downward... The upward movement of the moving plate 4 causes the rotating wheel 515 to slide downward relative to the V-shaped part 5131 and fall into the bending point 5111 of the V-shaped part 5131. The bending point 5111 limits the rotating wheel 515, thereby preventing the upward movement of the moving plate 4 by restricting the downward movement of the rotating wheel 515. Under the action of the pulling force of the pull rod 514 on the moving plate 4 and the elastic force of the first spring 512 itself, the moving plate 4 is further limited and fixed. Thus, the battery body can be clamped and fixed at the same time as the battery body is inserted into the battery housing cavity, and the moving plate 4 is limited at the same time. This facilitates the installation and removal of the battery body without the need for subsequent fixing and limiting operations of the battery body. The operation is simple and convenient.

[0027] Among them, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the track groove 513 consists of a V-shaped part 5131 in the middle and inclined parts 5132 on both sides. The bending point 5111 at the upper end of the V-shaped part 5131 is offset from the bending point 5111 at the lower end, so that the rotating wheel 515 can move smoothly from the V-shaped part 5131 to the inclined part 5132.

[0028] In this embodiment, the intersection of the V-shaped portion 5131 and the inclined portions 5132 on both sides adopts a rounded transition, and the radius of curvature of the upper arc is greater than that of the lower arc, so that when the movable plate 4 is pulled and limited, the rotating wheel 515 can move smoothly from the inclined portion 5132 to the V-shaped portion 5131, and when the limitation on the movable plate 4 is released, the rotating wheel 515 can move smoothly from the V-shaped portion 5131 to the inclined portion 5132.

[0029] Among them, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limiting unit 52 includes multiple hinge rods 521 hinged above the moving plate 4. The limiting frame 3 has a sliding groove 522 and a locking plate 523 is slidably installed in the sliding groove 522. The top of the hinge rod 521 is hinged to the locking plate 523 on the same side.

[0030] Specifically, during the downward movement of the movable plate 4, the hinge rod 521 pulls the clamping plate 523, causing the clamping plate 523 to gradually extend out of the slide groove 522. When the rotating wheel 515 moves to the bend of the V-shaped part 5131, the clamping plate 523 moves to the top of the battery body, locking and limiting the battery body in the vertical direction to prevent the battery body from moving in the vertical direction. It also works with the clamping plate 518 to clamp and fix the battery body in multiple directions, further improving the stability of fixing the battery body. When it is necessary to release the clamping and fixing of the battery body, press the battery body downwards. The pressure on the battery body causes the moving plate 4 to move downwards, causing the rotating wheel 515 to move upwards within the V-shaped portion 5131 of the track groove 513. When the rotating wheel 515 moves to the highest point of the track groove 513, the downward pressure resistance increases significantly. At this time, the pressure acting on the battery body is released, and the V-shaped portion 5131 releases its restriction on the rotating wheel 515, allowing the rotating wheel 515 to smoothly return to its original position via the inclined portion 5132. That is, the pull rod 514 releases its restriction pull on the moving plate 4, allowing the moving plate 4 to smoothly return to its original position under the action of the elastic force of the first spring 512. During the upward movement and repositioning process of the moving plate 4, the pressure increases significantly. The hinge rod 521 drives the clamping plate 523 to move away from the battery body, causing the clamping plate 523 to reset and be stored in the slide groove 522. This prevents the clamping plate 523 from interfering with the upward movement of the moving plate 4 and the battery body. As the moving plate 4 continues to reset upward, the toothed plate 5110 and the gear 519 mesh and contact again, causing the rotating shaft 516 and the threaded rod 517 to reverse. This causes the two clamping plates 518 to move away from each other and release the limiting fixation on the battery body. Thus, by simply pressing down on the battery body, the limiting fixation on the battery body can be released and the battery body can be removed from the battery housing cavity. This facilitates the installation and removal of the battery body, making the operation simple and convenient.

[0031] Among them, such as Figure 3 and Figure 9 As shown, the slide 522 consists of a horizontal groove 5221 for sliding the card plate 523 and a vertical groove 5222 for moving the hinge rod 521. The width of the horizontal groove 5221 is greater than the width of the vertical groove 5222, which can guide and limit the movement of the card plate 523 and ensure the stability of the card plate 523 during movement.

[0032] The first spring 512 is provided with a telescopic rod 53. The two ends of the telescopic rod 53 are fixedly connected to the bottom of the moving plate 4 and the housing 1, respectively. By setting the telescopic rod 53, the extension and retraction of the first spring 512 can be supported and limited to ensure the stability of the first spring 512 during extension and retraction. At the same time, the first spring 512 can guide and limit the moving plate 4 when it moves upward, so as to prevent the moving plate 4 from deviating or tilting during the up and down movement.

[0033] Among them, such as Figure 1 , Figure 7 and Figure 8 As shown, the quick-release assembly 7 includes a rotating shaft 71 rotatably mounted on the cover plate 6. A rotating disk 72 is fixedly mounted on the bottom end of the rotating shaft 71. Four connecting rods 73 are hinged on the rotating disk 72. Insert plates 74 are slidably mounted on the four sides of the cover plate 6. Each insert plate 74 is hinged to the connecting rod 73 on the same side. A torsion spring 75 is sleeved on the rotating shaft 71. The two ends of the torsion spring 75 are fixedly connected to the rotating disk 72 and the cover plate 6, respectively. The insert plates 74 are used in conjunction with the slots 76 on the same side. The top end of the rotating shaft 71 extends to the outside of the cover plate 6 and a knob 77 is fixedly mounted thereon. A receiving groove for the knob 77 is provided on the cover plate 6.

[0034] Specifically, rotating the knob 77 drives the rotating shaft 71 and the rotating disk 72 to rotate. The rotation of the rotating disk 72 will torsion and compress the torsion spring 75. At the same time, the rotation of the rotating disk 72 drives the insert plate 74 to move closer to the rotating disk 72 through the connecting rod 73, and then the cover plate 6 is closed on the limiting frame 3. Then, the knob 77 is released, and the torsion spring 75 drives the rotating disk 72 and the insert plate 74 to return to their original positions under its own elastic force, and inserts the insert plate 74 into the slot 76 on the same side, thus completing the locking and limiting of the cover plate 6. Similarly, when it is necessary to remove the cover plate 6, the knob 77 is rotated again, so that the rotating disk 72 rotates and moves the insert plate 74 out of the slot 76 on the same side, which can release the lock between the cover plate 6 and the limiting frame 3, and quickly remove the cover plate 6 from the limiting frame 3, which is convenient for subsequent installation and removal of the battery body. The structure is simple and easy to use.

[0035] Among them, such as Figure 7 and Figure 8As shown, the insert plate 74 has a downward inclined surface 78, which works in conjunction with the limiting frame 3. By setting the inclined surface 78, when installing the cover plate 6 and the limiting frame 3, the cover plate 6 can be pressed down. When the inclined surface 78 of the insert plate 74 is squeezed by the limiting frame 3, it will move towards the rotating disk 72 and drive the rotating disk 72 to rotate under the action of the connecting rod 73, thus compressing the torsion spring 75. When the slot 76 and the insert plate 74 are aligned, the pressure on the inclined surface 78 of the insert plate 74 disappears, and the insert plate 74 returns to its original position under the elastic force of the torsion spring 75, so that the insert plate 74 is inserted into the slot 76 on the same side, completing the locking connection of the cover plate 6. This further improves the convenience of installation connection between the cover plate 6 and the limiting frame 3.

[0036] Among them, such as Figure 7 and Figure 8 As shown, each insert plate 74 is fixedly installed with a limiting part 79, and the cover plate 6 is provided with a limiting groove 710 for use with the limiting part 79. Through the cooperation of the limiting part 79 and the limiting groove 710, the movement of the insert plate 74 in the limiting groove 710 is guided and limited, so as to maintain the stability of the insert plate 74 during movement.

[0037] During operation, the battery body is inserted into the battery receiving cavity under the guidance and limitation of the limiting frame 3. During the insertion process, the battery body pushes the moving plate 4 downward through the pressure plate 511 and compresses the first spring 512. When the moving plate 4 moves downward, it will drive the rotating shaft 516 and the threaded rods 517 on both sides to rotate under the cooperation of the gear 519 and the toothed plate 5110. This causes the clamping plates 518 on both sides to move closer to each other and clamp and fix the battery body laterally during the downward movement of the moving plate 4. After the clamping plates 518 fix the battery, the gear 519 and the toothed plate 5110 disengage, so that the rotating shaft 516 will not rotate when the moving plate 4 continues to move downward. With the self-locking characteristic of the threaded rod 517, the stability of the battery body during subsequent use can be guaranteed, and damage to the battery body can be avoided during use. When the movable plate 4 moves downward, the cooperation of the track groove 513, the pull rod 514, and the rotating wheel 515 causes the rotating wheel 515 to slide upward along the track groove 513. When the rotating wheel 515 moves to the highest point of the track groove 513, the movable plate 4 reaches its maximum downward position, and the downward resistance increases significantly. At this time, the pressure acting on the battery body is released, and the first spring 512 pushes the movable plate 4 upward to reset a certain distance under its own elasticity. Since the gear 519 has disengaged from the toothed plate 5110, the upward movement of the movable plate 4 will not drive the rotating wheel 515. As shaft 516 rotates, clamping plate 518 maintains stable clamping of the battery body; as moving plate 4 moves upward, rotating wheel 515 slides downward relative to V-shaped part 5131 and falls into the bending point 5111 of V-shaped part 5131. Bending point 5111 limits rotating wheel 515, thereby preventing moving plate 4 from moving upward by limiting the downward movement of rotating wheel 515. Under the action of the pulling force of pull rod 514 on moving plate 4 and the elastic force of the first spring 512 itself, moving plate 4 is further limited and fixed. Then, rotating the knob 77 drives the rotating shaft 71 and the rotating disk 72 to rotate. The rotation of the rotating disk 72 will torsion and compress the torsion spring 75. At the same time, the rotating disk 72 rotates and drives the insert plate 74 to move closer to the rotating disk 72 through the connecting rod 73. Then, the cover plate 6 is closed on the limiting frame 3. Then, the knob 77 is released. Under the action of its own elasticity, the torsion spring 75 drives the rotating disk 72 and the insert plate 74 to reset and insert the insert plate 74 into the slot 76 on the same side, thus completing the locking and limiting of the cover plate 6. When the battery body needs to be disassembled and replaced, rotate knob 77 again to make the rotating disk 72 rotate and move the insert plate 74 out of the slot 76 on the same side. This will release the lock between the cover plate 6 and the limiting frame 3. Quickly move the cover plate 6 out of the limiting frame 3, and then press the battery body down. This will cause the rotating wheel 515 to move upward in the V-shaped part 5131 of the track groove 513. When the rotating wheel 515 moves to the highest point of the track groove 513, the downward pressure resistance will increase significantly. At this time, release the pressure acting on the battery body. The V-shaped part 5131 will release the limiting force on the rotating wheel 515, allowing the moving plate 4 to move under the elastic force of the first spring 512. The battery body is successfully reset, and the hinge rod 521 drives the clamping plate 523 to move away from the battery body, preventing the clamping plate 523 from interfering with the upward movement of the moving plate 4 and the battery body. As the moving plate 4 continues to move upward, the toothed plate 5110 and the gear 519 mesh again, and drive the rotating shaft 516 and the threaded rod 517 to reverse, so that the two clamping plates 518 move away from each other and release the limiting fixation on the battery body. Thus, by simply pressing down on the battery body, the limiting fixation on the battery body can be released and the battery body can be removed from the battery housing cavity, which is convenient for the installation and removal of the battery body. The operation is simple and convenient.
