Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically a heating device for cooking steak. Background Technology

[0002] In daily life, traditional cooking methods for steak, such as frying pans and ovens, often make it difficult to precisely control the temperature and time when making steak, resulting in steaks that are either burnt on the outside and raw on the inside or undercooked. The emergence of steak machines has reduced the difficulty of cooking steaks, allowing people to conveniently fry and cook steaks.

[0003] However, most steak grills on the market have a flip-top design, using a double-sided flip-top clamping method. You manually press one of the movable grill pans onto the steak to be grilled, so that both sides of the steak can be heated at the same time. However, this flip-top clamping method is only suitable for steaks of a certain thickness. Steaks that are too thin may not be clamped properly, resulting in one side being cooked while the other side is still raw. Steaks that are too thick may not be clamped properly, resulting in one side being burnt while the other side is still raw. It cannot be adapted to cooking steaks of a wider range of thicknesses.

[0004] To address the above shortcomings, we need to develop a heating device that can be used for cooking steaks to meet the needs of a wide range of users. Utility Model Content

[0005] In response to the aforementioned problems with existing steak machines, such as their inability to cook steaks of varying thicknesses, the technical solution adopted by this utility model is as follows:

[0006] A heating device for cooking steaks includes a housing having a heating and cooking cavity and a lifting transmission mechanism installed in the heating and cooking cavity. A first heating plate is installed on the side of the heating and cooking cavity away from the lifting transmission mechanism, and a second heating plate is installed on the lifting transmission mechanism. The area between the first heating plate and the second heating plate is a heating and cooking area. The lifting transmission mechanism drives the second heating plate to rise or fall vertically, so that the height of the heating and cooking area in the vertical direction is variable.

[0007] As described above, a heating device for cooking steaks includes a housing comprising a fixed base and a movable flip cover. The movable flip cover is hinged to and covers the fixed base to form a heating and cooking cavity. The lifting transmission mechanism is installed on the fixed base near the bottom of the heating and cooking cavity, and the first heating plate is installed on the movable flip cover near the top of the heating and cooking cavity.

[0008] As described above, a heating device for cooking steaks has a first heating plate that is hooked onto the inner cavity side of the movable flip cover via a back-hook. An elastic element for shock absorption and resetting is installed between the first heating plate and the movable flip cover. When the first heating plate is pressed into contact with a micro switch of the movable flip cover, the micro switch triggers the lifting transmission mechanism to drive the second heating plate to descend.

[0009] As described above, a heating device for cooking steaks has an external base support foot installed near the hinge of the movable flap to support the force on the flap. The external base support foot extends from the hinge of the movable flap toward the bottom and has a support foot stabilizing plane at the bottom.

[0010] As described above, a heating device for cooking steaks has a control panel for operating the device mounted on the fixed base at a position away from the hinged movable cover. The control panel uses a touch-sensitive electronic display screen and is electrically connected to a heating element for heating and a lifting transmission mechanism.

[0011] As described above, a heating device for cooking steak has a heat insulation cover installed on the side of the first heating plate away from the heating and cooking area, and / or a heat insulation cover installed on the side of the second heating plate away from the heating and cooking area.

[0012] The heat insulation cover is equipped with a heating element for heating to the cooking temperature.

[0013] As described above, a heating device for cooking steaks has a heat insulation component installed inside the casing. The heat insulation component is located at the bottom of the heating and cooking cavity and / or inside the heat insulation cover.

[0014] As described above, a heating device for cooking steaks includes a lifting transmission mechanism comprising a fixing member for limiting the installation position, a transmission component mounted on the fixing member, and a driver for providing power. The driver drives the transmission component to move the second heating plate toward or away from the first heating plate.

[0015] As described above, a heating device for cooking steaks includes a transmission assembly comprising a transmission shaft, transmission components, a connecting rod, and a support rod. Two transmission components are threadedly connected to the transmission shaft. The transmission shaft rotates and drives the two transmission components to move closer or further apart through threaded transmission. One end of the connecting rod is hinged to the transmission component, and the other end of the connecting rod is hinged to a support frame installed at the bottom of the second heating plate via the support rod.

[0016] As described above, a heating device for cooking steaks has a directional limiting groove on the inner wall of the heating and cooking cavity. The directional limiting groove extends from a position near the second heating plate toward a position near the first heating plate, and the sliding wheel of the support frame is installed in the directional limiting groove.

[0017] The beneficial effects of this utility model are as follows:

[0018] The casing of this utility model is equipped with a lifting transmission mechanism for adjusting the separation distance between the heating plates. The lifting transmission mechanism drives the heating plates to rise or fall, thereby expanding the range of thickness adjustment for cooking steaks. Whether the steak is thick or thin, it can be cooked within the lifting range. In addition, the mechanical lifting grill pan can also replace manual pressing of the steak during frying. There is no need to manually cook the steak during frying. The top pressure of the mechanical lifting can also achieve double-sided pressing of the steak, strengthen the full contact between the grill pan and the steak, enhance the heating effect of the steak, and make it convenient for users.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figures 1 to 7 The heating device shown includes a housing 1 with a heating and cooking cavity 11 and a lifting transmission mechanism 2 installed in the heating and cooking cavity 11. A first heating plate 3 is installed on the side of the heating and cooking cavity 11 away from the lifting transmission mechanism 2, and a second heating plate 4 is installed on the lifting transmission mechanism 2. The heating and cooking area 12 is located between the first heating plate 3 and the second heating plate 4. The lifting transmission mechanism 2 drives the second heating plate 4 to rise or fall vertically, so that the height of the heating and cooking area 12 in the vertical direction is variable.

[0030] Specifically, in this embodiment, taking the cooking of steak as an example, the outer casing 1 is the outer shell of the heating device, and the interior of the outer casing 1 is the heating and cooking cavity 11 for cooking. A lifting and lowering transmission mechanism 2 is installed in the heating and cooking cavity 11 to facilitate lifting and moving the steak. To ensure the steak is fully heated and cooked through by clamping it from both sides, a first heating plate 3 and a second heating plate 4 are respectively provided on the upper and lower sides of the steak. Heating elements are installed on the first heating plate 3 and the second heating plate 4. The first heating plate 3 is located above the steak being cooked, i.e., on the side of the heating and cooking cavity 11 away from the lifting and lowering transmission mechanism 2, and the second heating plate 4 is located below the steak being cooked, i.e., on top of the lifting and lowering transmission mechanism 2. The cooking surfaces of the first heating plate 3 and the second heating plate 4 face each other, and the space between the first heating plate 3 and the second heating plate 4 is the heating and cooking area for cooking the steak. In area 12, when the lifting transmission mechanism 2 drives the second heating plate 4 to lift the steak, the steak is raised until it contacts the first heating plate 3. Under the clamping of the first heating plate 3 and the second heating plate 4, the steak is cooked at high temperature. After cooking, the user can open the outer casing 1 to take out the finished steak and enjoy it. Then, the lifting transmission mechanism 2 drives the second heating plate 4 to lower and reset, or maintain the lifting posture to facilitate the user to clean the oil stains on the second heating plate 4. In order to avoid oil stains spilling outside the heating plate, the lifting transmission mechanism 2 preferably rises or falls in the vertical direction, so that the height of the heating and cooking area 12 forms a variable, adjustable and controllable spatial change in the vertical direction, thereby expanding the thickness adjustment range of the cooked steak. Whether it is a thick steak or a thin steak, it can be adapted to cooking within the lifting range. There is no need to manually cook the steak during frying, which is convenient for users.

[0031] In addition to its application to steak, the heating device of this application can also be used for cooking other ingredients such as chicken, pork, and lamb chops, or for cooking other dishes such as mashed potatoes, vegetable platters, meat chunks, and meat sauce. Further details and limitations will not be elaborated upon here.

[0032] Example 2:

[0033] Based on Example 1, such as Figures 1 to 5 The heating device shown is used for cooking steaks. The housing 1 includes a fixed base 13 and a movable flip cover 14. The movable flip cover 14 is hinged to and covers the fixed base 13 to form a heating and cooking cavity 11. A lifting transmission mechanism 2 is installed on the fixed base 13 near the bottom of the heating and cooking cavity 11. A first heating plate 3 is installed on the movable flip cover 14 near the top of the heating and cooking cavity 11.

[0034] Specifically, in this embodiment, in order to facilitate opening the outer casing 1 and entering the internal heating and cooking cavity 11, the base part of the outer casing 1 is a fixed base 13, and the top cover part of the outer casing 1 is a movable flip cover 14. The movable flip cover 14 is hinged to close the fixed base 13 to form the heating and cooking cavity 11. Before cooking, the movable flip cover 14 can be flipped open around the hinge to put in the food. After cooking, the movable flip cover 14 can be flipped open again around the hinge to take out the food. After the movable flip cover 14 is opened, it can be limited on the fixed base 13 by the hinge, so that the user does not need to place it in a separate position. This avoids the first heating plate 11 of the movable flip cover 14 from being contaminated by the outside world and also saves placement space. After the movable flip cover 14 is closed, the inner heating and cooking cavity 11 is formed inside the outer casing 1, and the cooking process can be carried out smoothly.

[0035] Specifically, in this embodiment, the lifting transmission mechanism 2 is installed on the fixed base 13 near the bottom of the heating and cooking cavity 11, so as to facilitate smooth lifting and lowering in the vertical direction when lifting.

[0036] Furthermore, as a preferred embodiment, such as Figures 1 to 5 The heating device shown is used for cooking steaks. The movable flip cover 14 is provided with a flip cover handle 143 for the user to hold and open. The flip cover handle 143 is located at a position away from the hinge of the movable flip cover 14 and the fixed base 13. When in use, the user holds the flip cover handle 143 and flips it open towards the hinge of the movable flip cover 14 to put or take out food into the heating and cooking cavity 11.

[0037] Furthermore, as a preferred embodiment, such as Figures 1 to 5The heating device shown is used for cooking steaks. The movable flip cover 14 is fastened to the fixed base 13 by a snap-on latch 132. The snap-on latch 132 is a latching and limiting structure installed on the fixed base 13 to lock the movable flip cover 14. After the food is put in, the movable flip cover 14 closes to the fixed base 13 and is locked by the snap-on latch 132 to prevent the food from falling out when the movable flip cover 14 opens during cooking. In addition, the snap-on latch 132 is used in conjunction with the flip cover handle 143, which also makes it easy for users to carry the outer shell 1 of the device outdoors and move it at will. There is no need to worry that the movable flip cover 14 will suddenly open during the movement, causing the fixed base 13 to fall off or uneven force to increase the user's hand strength, making it convenient for users to use.

[0038] Furthermore, as a preferred embodiment, such as Figures 6 to 7 The heating device shown is used for cooking steaks. The first heating plate 3 is hooked to the inner cavity side buckle hole 141 of the movable flip cover 14 by the plate back buckle 31. An elastic element 5 for shock absorption and reset is installed between the first heating plate 3 and the movable flip cover 14. After the first heating plate 3 is pressed and contacts the micro switch 142 of the movable flip cover 14, the micro switch 142 triggers the lifting transmission mechanism 2 to drive the second heating plate 4 to descend.

[0039] Specifically, in this embodiment, the back buckle 31 is a limiting buckle structure set on the back of the first heating plate 3, used to limit the installation position of the first heating plate 3 on the inner side of the movable flip cover 14. The inner side of the movable flip cover 14 is provided with an inner cavity side buckle hole 141 for installing the first heating plate 3. The inner cavity side buckle hole 141 has a certain space in height for the back buckle 31 to move up and down. The movable flip cover 14 is equipped with a micro switch 142 on the side near the first heating plate 3 for the first heating plate 3 to be pressed and contacted. An elastic element 5 for absorbing impact is also installed between the first heating plate 3 and the movable flip cover 14. The elastic element 5 is preferably a spring structure.

[0040] In use, when the lifting transmission mechanism 2 drives the second heating plate 4 to lift the steak and raise it until it contacts the first heating plate 3, the first heating plate 3 is pressed and continues to rise until it contacts the micro switch 142. The micro switch 142 triggers the lowering of the lifting transmission mechanism 2. When the lifting transmission mechanism 2 drives the second heating plate 4 to fall, the steak is removed from the first heating plate 3. The pressure on the first heating plate 3 is eliminated and it is elastically pressed down by the elastic element 5, causing the plate back buckle 31 to fall back to the bottom of the hole 141 on the inner cavity side. At this time, the first heating plate 3 has been removed from the micro switch 142, that is, the micro switch 142 is not in the state of not triggering the lowering of the lifting transmission mechanism 2. The lifting transmission mechanism 2 rises again, and the lifting and lowering is repeated several times, so that the steak is repeatedly pressed down several times, which simulates the effect of a person using a spatula to repeatedly press the steak in actual cooking, further improving the cooking effect.

[0041] Furthermore, as a preferred embodiment, in order to address the problem that the fixed base 13 may tip over due to unilateral force after the movable flip cover 14 is opened, such as... Figure 2 , Figure 6 The heating device shown is used for cooking steaks. The fixed base 13 is equipped with an external base support leg 15 for supporting the force of the flip cover near the hinge position with the movable flip cover 14. The external base support leg 15 extends from the hinge position of the movable flip cover 14 toward the bottom and has a support stabilizing plane 151 at the bottom.

[0042] Specifically, in this embodiment, the external base support 15 is supported by the support stabilizing plane 151 below the hinge position between the fixed base 13 and the movable flip cover 14. The external base support 15 preferably adopts a structure that is narrow at the top and wide at the bottom, so that there is sufficient support below the hinge position after the movable flip cover 14 is opened, avoiding the fixed base 13 from tipping over due to the excessive weight of the heating plate of the movable flip cover 14, and making it convenient for users to use.

[0043] Furthermore, as a preferred embodiment, such as Figures 1 to 5 The heating device shown is used for cooking steaks. Each corner of the bottom of the fixed base 13 is provided with a base foot 133 for easy placement. At least three base feet 133 can support the placement of the fixed base 13 at the same time, preferably four base feet 133, which improves the stability of the housing 1. In addition, when used in conjunction with the external base support 15, it can prevent the fixed base 13 from tipping over due to the excessive weight of the heating plate of the movable flip cover 14, making it convenient for users.

[0044] Furthermore, as a preferred embodiment, to further facilitate user operation of the heating equipment, such as... Figures 1 to 5 The heating device shown is used for cooking steaks. The fixed base 13 is equipped with a control panel 131 for operating the device at a position away from the hinged hinge to the movable flip cover 14. The control panel 131 adopts a touch electronic display screen and is electrically connected to the heating element 33 for heating and the lifting transmission mechanism 2.

[0045] Specifically, in this embodiment, the entire surface of the control panel 131 adopts an electronic display screen structure design. Since users' hands may be oily during actual cooking, and oil residue is difficult to clean from physical buttons, it is preferable to use a touch-sensitive method on the back of the electronic display screen instead of physical buttons. When cleaning, it is only necessary to wipe the dirt off the surface of the electronic display screen. The control panel 131 is electrically connected to the heating element 33 for heating and the lifting transmission mechanism 2. Users can intuitively control the heating temperature of the heating element 33 from the control panel 131 to control the doneness of the steak, and can also intuitively control the lifting and lowering of the lifting transmission mechanism 2 from the control panel 131 to control the cooking quality of the steak.

[0046] Furthermore, as a preferred embodiment, to further facilitate user operation of the heating equipment, such as... Figure 3 The heating device shown is used for cooking steaks. The control panel 131 is equipped with a rotary handle 134 for easy temperature control. The rotary handle 134 is connected to the adjustment unit of the control panel 131. The user can adjust the temperature rise and fall of the heating element 33 by rotating the rotary handle 134.

[0047] Furthermore, as a preferred embodiment, in order to improve heat concentration, increase heating efficiency, and reduce heat loss, such as Figures 4 to 7 The heating device shown is used for cooking steaks. A heat insulation cover 32 for heat preservation is installed on the side of the first heating plate 3 away from the heating and cooking area 12, or a heat insulation cover 32 for heat preservation is installed on the side of the second heating plate 4 away from the heating and cooking area 12. A heating element 33 for heating the cooking temperature is installed inside the heat insulation cover 32.

[0048] Specifically, in this embodiment, the heating element 33 is a heating unit for heating the steak, preferably a heating wire or a heating tube. The heat insulation cover 32 is installed on the back of the heating plate. The heating element 33 extends from the side of the heat insulation cover 32 near the heating plate and is bent around the outer edge of the heating plate. After being powered on, the heating element 33 begins to heat up and transfers heat to the heating plate. The heating plate heats the steak. The heat insulation cover 32 concentrates the heat from the heating element 33 toward the heating plate, improving heat concentration, heating efficiency, and reducing heat loss. It can also reduce the impact of heat on the external structure of the heat insulation cover 32.

[0049] Furthermore, as a preferred embodiment, in order to improve heat concentration, increase heating efficiency, and reduce heat loss, such as Figures 4 to 7The heating device shown is suitable for cooking steaks. A heat insulation cover 32 for heat preservation is installed on the side of the first heating plate 3 away from the heating and cooking area 12. A heat insulation cover 32 for heat preservation is also installed on the side of the second heating plate 4 away from the heating and cooking area 12. Heating elements 33 for heating the cooking temperature are installed on both the side of the first heating plate 3 away from the heating and cooking area 12 and the side of the second heating plate 4 away from the heating and cooking area 12. The heating elements 33 are located inside the heat insulation cover 32. Specifically, in this embodiment, both the first heating plate 3 and the second heating plate 4 are equipped with heat insulation covers 32, which concentrate heat from two different heating plates, further improving heat concentration, heating efficiency, and reducing heat loss. In addition, it can also reduce the impact of heat on the external structure of the heat insulation cover 32.

[0050] Furthermore, as a preferred embodiment, in order to improve heat concentration, increase heating efficiency, and reduce heat loss, such as Figures 4 to 7 The heating device shown is used for cooking steaks. The casing 1 is equipped with a heat insulation component inside. The heat insulation component is located at the bottom of the heating and cooking cavity 11. Specifically, in this embodiment, the heat insulation component can be one of ceramic fiber, rock wool, expanded polystyrene board, aluminum foil composite material, etc., to further enhance the concentration of heat from the heating element 33 toward the heating plate, improve heat concentration, improve heating efficiency, reduce heat loss, and also reduce the impact of heat on the external structure of the heat insulation cover 32.

[0051] Furthermore, as a preferred embodiment, in order to improve heat concentration, increase heating efficiency, and reduce heat loss, such as Figures 4 to 7 The heating device shown is used for cooking steaks. The casing 1 is equipped with a heat insulation component inside the casing. The heat insulation component is located inside the heat insulation cover 32. Specifically, in this embodiment, the heat insulation component can be one of ceramic fiber, rock wool, expanded polystyrene board, aluminum foil composite material, etc., to further enhance the concentration of heat from the heating element 33 toward the heating plate, improve heat concentration, improve heating efficiency, reduce heat loss, and also reduce the impact of heat on the external structure of the heat insulation cover 32.

[0052] Example 3:

[0053] Based on Example 1, such as Figures 4 to 7 The heating device shown is used for cooking steaks. The lifting transmission mechanism 2 includes a fixing member 21 for limiting the installation position, a transmission assembly 22 mounted on the fixing member 21, and a driver 23 for providing power. The driver 23 drives the transmission assembly 22 to move the second heating plate 4 toward or away from the first heating plate 3.

[0054] Specifically, in this embodiment, the fixing member 21 is an installation accessory for installation inside the steak cooking equipment, which can fix the installation positions of the transmission assembly 22 and the driver 23 to the body shell of the steak cooking equipment. The fixing member 21 is preferably a sheet metal part formed by bending process, which is convenient for design, manufacturing and installation. The driver 23 can be a motor that can rotate in both directions as a power source. The motor can be connected to the transmission shaft 221 by an adapter shaft so that the transmission shaft 221 can rotate synchronously with the output end of the motor. The transmission assembly 22 includes a transmission shaft 221 for transmitting power, a transmission member 222 for driving the connecting rod 223 and a connecting rod 223 for driving the second heating plate 4. The connecting rod 223 can be composed of several connecting rods and hinge components. When the driver 23 drives the transmission shaft 221 to rotate, the transmission member 222... The connecting rod 223 converts the axial movement of the transmission component 222 into vertical movement by moving axially along the central axis of the transmission shaft 221, causing the second heating plate 4 to rise or fall, thus adjusting the thickness range for steak cooking. Furthermore, the driver 23 drives the second heating plate 4, located below the steak, upwards via the transmission component 22 to press the steak being heated. Combined with the fixed grill pan above the steak, the mechanical lifting of the second heating plate 4 can replace manual pressing during cooking. No manual pressing is required during cooking; the mechanical lifting pressure effectively presses the steak firmly on both sides, enhancing the contact between the grill pan and the steak, improving heating efficiency, and ensuring even heating on both sides for better cooking results and user convenience.

[0055] Furthermore, as a preferred embodiment, such as Figures 4 to 7 The heating device shown can be used for cooking steaks. The transmission assembly 22 includes a transmission shaft 221, a transmission component 222, a connecting rod 223, and a support rod 224. The two transmission components 222 are respectively threadedly connected to the transmission shaft 221. The transmission shaft 221 rotates and drives the two transmission components 222 to move closer or further apart through the threaded transmission. One end of the connecting rod 223 is hinged to the transmission component 222, and the other end of the connecting rod 223 is hinged to the support frame 225 installed at the bottom of the second heating plate 4 through the support rod 224.

[0056] Specifically, in this embodiment, the transmission component 222 is movably connected to the transmission shaft 221 using a threaded structure. The outer surface of the transmission shaft 221 is provided with an external thread. One of the two transmission components 222 uses a left-hand thread, and the other of the two transmission components 222 uses a right-hand thread. One transmission component 222 performs threaded transmission by engaging the external thread of the transmission shaft 221 with a left-hand internal thread, and the other transmission component 222 performs threaded transmission by engaging the external thread of the transmission shaft 221 with a right-hand internal thread.

[0057] When the second heating plate 4 needs to be raised, the driver 23 (i.e., the drive motor) rotates forward, driving the transmission shaft 221 to rotate forward. At this time, the two transmission components 222 move away from each other along the axial direction of the transmission shaft 221. The two transmission components 222 drive the connecting rod 223 from different directions to lift the support frame 225 through the support rod 224. When the support frame 225 is raised, the second heating plate 4 is raised. When the second heating plate 4 needs to be lowered, the driver 23 reverses, driving the transmission shaft 221 to reverse. At this time, the two transmission components 222 move closer to each other along the axial direction of the transmission shaft 221. The two transmission components 222 drive the connecting rod 223 to lower the support frame 225 through the support rod 224. When the support frame 225 is lowered, the second heating plate 4 is lowered, thus achieving the lifting and lowering effect of the second heating plate 4.

[0058] Furthermore, as a preferred embodiment, such as Figure 8 The heating device shown is used for cooking steaks. The inner side wall of the heating and cooking cavity 11 is provided with a directional limiting slot 111. The directional limiting slot 111 extends from the position near the second heating plate 4 toward the direction near the first heating plate 3. The sliding groove wheel 226 of the support frame 225 is installed in the directional limiting slot 111.

[0059] Specifically, in this embodiment, the directional limiting slot 111 is used to limit the lifting and lowering direction of the support 225. The directional limiting slot 111 can be symmetrically arranged on the inner side walls of the heating and cooking cavity 11 in different directions to improve the stability of the second heating plate 4 on both sides of the lifting and lowering movement. The support 225 is equipped with a sliding wheel 226 for fitting into the directional limiting slot 111. The support 225 can smoothly slide up and down along the edge of the directional limiting slot 111 through the sliding wheel 226. The sliding wheel 226 reduces friction between the support and the directional limiting slot 111 and reduces friction loss.

[0060] Furthermore, as a preferred embodiment, such as Figure 8 The heating device shown is used for cooking steaks. Inside the outer casing 1, a tension spring 16 is installed to reduce the load on the lifting transmission mechanism 2 during lifting. One end of the tension spring 16 is hooked onto the sliding wheel 226 of the support frame 225 and is in a lower position. The other end of the tension spring 16 is hooked onto the inner side wall of the heating and cooking cavity 11 and is in a higher position. When the second heating plate 4 is raised, the tension spring 16 generates an upward pulling force on the sliding wheel 226, reducing the load on the lifting transmission mechanism 2 during lifting. When the second heating plate 4 is lowered, the tension spring 16 generates an upward pulling force on the sliding wheel 226, improving the elastic buffering of the lifting transmission mechanism 2 during descent.

[0061] Furthermore, as a preferred embodiment, such as Figures 4 to 7The heating device shown can be used for cooking steaks. The tension spring 16 can be symmetrically arranged on the inner side walls of the heating and cooking cavity 11 in different directions to further improve the stability of the second heating plate 4 on both sides of the lifting and moving.

[0062] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
