[0002] A grill is a tool for cooking food. It heats one side of the food, flips it over to heat both sides of the food, or heats both sides of the food simultaneously, so that the middle part of the food can also be heated at high temperature, thereby achieving the purpose of cooking food.

[0003] Prior art CN218943036U discloses a grilling machine comprising an upper grill assembly and a lower grill assembly, the upper and lower grill assemblies being rotatably connected via a hinge assembly, defining a cooking space between the upper and lower grill assemblies. The grilling machine further comprises an adjustment assembly movably disposed on the upper grill assembly or the lower grill assembly, the adjustment assembly comprising a lifting member, a driving member, and an operating member, the driving member having an inclined abutting surface, one end of the lifting member engaging the abutting surface and the other end for abutting the lower grill assembly or the upper grill assembly, the operating member having one end connected to the driving member and the other end extending out of the upper grill assembly or the lower grill assembly, the operating member driving the driving member to move so that different height areas of the abutting surface abut the lifting member to adjust the height of the cooking space.

[0004] In the above-mentioned grilling machine, two groups of lifting parts are provided, and the two groups of lifting parts are connected by a transmission part. When adjusting the height of the cooking space, the driving part is rotated, and the inclined abutting surface on the lower side of the driving part abuts on the transmission part, so as to drive the lifting parts on both sides to support downward on the lower baking tray assembly, so that the moving distance of the lifting parts is consistent with the height change of the inclined abutting surface. Since the thickness of the upper baking tray assembly is fixed, the height adjustment range of the upper baking tray assembly is small. Utility Model Content

[0005] The purpose of the present invention is to provide a grilling machine that solves the problem of a small height adjustment range of the upper grilling plate assembly and expands the height adjustment range of the upper grilling plate assembly to improve the applicability of the grilling machine to foods of different thicknesses.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a frying and grilling machine, comprising an upper baking tray assembly and a lower baking tray assembly, the upper baking tray assembly is provided with a support adjustment assembly, the support adjustment assembly comprises a rotary adjustment member, a lever and a support member, the rotary adjustment member rotates horizontally relative to the upper baking tray assembly, the rotary adjustment member is provided with an actuating curved surface that changes in height in the circumferential direction, the lever is rotatably connected to the upper baking tray assembly, the lever abuts the actuating curved surface and is connected to the support member, the rotary adjustment member is rotated to drive the lever to realize the lifting and lowering of the support member, the support member extends downward from the upper baking tray assembly and abuts against the lower baking tray assembly, so that the upper baking tray assembly is away from the lower baking tray assembly.

[0007] After adopting the above technical solution, the utility model has the following advantages: the food to be grilled is placed between the upper grilling plate assembly and the lower grilling plate assembly, and the upper side and the lower side of the food are grilled respectively, thereby improving the efficiency of grilling food; when the thickness of the food is greater than the height of the space between the upper grilling plate assembly and the lower grilling plate assembly, the rotary adjusting member is rotated so that the end of the lever in contact with the rotary adjusting member slides relative to the actuating curved surface of the rotary adjusting member, and the part of the lever in contact with the rotary adjusting member moves relative to the lower grilling plate assembly, and the other part of the lever acts on the supporting member so that the supporting member moves downward and supports the lower grilling plate assembly, thereby lifting the upper grilling plate assembly upward relative to the lower grilling plate assembly, thereby increasing the height of the cooking space between the upper grilling plate assembly and the lower grilling plate assembly, making the cooking space of the grilling machine suitable for food of different thicknesses, and facilitating grilling of food of different thicknesses by the grilling machine. By leveraging the amplifying effect of the lever principle, the support member can be adjusted over a wide range of heights with a small change in the height of the actuating surface, reducing the height change requirements for the actuating surface. Furthermore, a small change in the height of the actuating surface can also adjust the upper grill assembly over a wide range of heights, thereby increasing the height adjustment range of the upper grill assembly. This allows the grill to accommodate a wider range of foods of varying thicknesses, further improving the grill's suitability for foods of varying thicknesses. The height adjustment of the cooking space also allows for optimal adaptation to foods with varying expansion coefficients.

[0008] Furthermore, the actuating curved surface is provided with self-locking planes at different height positions, and the lever abuts against the self-locking plane to keep the support member at the current position.

[0009] With the aforementioned technical solution, when the lever moves relative to the actuating curved surface to the self-locking plane, it abuts against the self-locking plane and stops rotating, maintaining the support member in its current position and fixing the height between the upper and lower grilling tray assemblies. Locking the self-locking plane improves the stability of the upper grilling tray assembly after height adjustment. By providing self-locking planes at different heights, multiple height levels can be created. This allows the upper grilling tray assembly to be raised to the appropriate height for a wider variety of food thicknesses, providing greater versatility. Furthermore, adjusting the upper grilling tray assembly to a more appropriate height ensures that its heating efficiency is not affected.

[0010] Furthermore, the lever is provided with multiple and distributed circumferentially around the rotary adjustment member, the actuating curved surface is in one-to-one contact with the lever, all actuating curved surfaces are separated from each other, and the ends of the actuating curved surfaces are provided with limiting ribs to prevent the lever from detaching; or, the lever is provided with multiple and distributed circumferentially around the rotary adjustment member, the actuating curved surfaces are in one-to-one contact with the lever and are connected to each other to form an annular curved surface.

[0011] By adopting the above-mentioned technical solution, when the lever adjusts the height of the upper baking tray assembly, it is supported and adjusted by multiple levers, thereby improving the stability of the upper baking tray assembly during the adjustment process. When the lever contacts the actuating surface, the limiting rib blocks the lever at the tail end of the actuating surface, thereby preventing the lever from moving to the highest point of the actuating surface and then detaching from the braking surface and falling, thereby preventing the upper baking tray assembly from suddenly falling after rising to the highest point. Multiple levers are distributed along the circumference of the rotary adjustment member, and the multiple levers are respectively abutted one-to-one with the multiple actuating surfaces. The multiple actuating surfaces are interconnected to form an annular surface, thereby improving the freedom of height adjustment of the upper baking tray assembly, and adjustment can be achieved by rotating the rotary adjustment member forward and backward.

[0012] Furthermore, the upper baking tray assembly includes a first upper cover and a first lower cover, the first upper cover and the first lower cover are connected, the lever is hinged to the first upper cover or the first lower cover, the support member extends downward from the first lower cover, the first lower cover is provided with a rotating shaft and an annular positioning groove, the rotating shaft extends upward, the bottom end of the rotating adjustment member is provided with an axial hole matching the rotating shaft and a positioning ring body inserted into the annular positioning groove, and the bottom end surface of the positioning ring body is provided with a protrusion to reduce friction.

[0013] The above-mentioned technical solution is adopted, and the lever is hinged to the first upper cover or the first lower cover. When the rotary adjustment member drives one end of the lever to rise, the lever rotates so that the other end of the lever abuts the support member downward. After the support member is abutted, it extends downward from the first lower cover and is supported on the lower baking tray assembly; during the adjustment process of the rotary adjustment member, the rotating shaft and the shaft hole cooperate to ensure that the lever and the rotary adjustment member are stably connected, and the positioning ring body is inserted into the annular positioning groove, further stabilizing the lever and the rotary adjustment member, thereby stably connecting the first upper cover and the first lower cover of the upper baking tray assembly, thereby improving the efficiency of the rotary adjustment member in adjusting the height of the upper baking tray assembly; in addition, the convex point on the bottom end surface of the positioning ring body reduces the contact area between the positioning ring body and the annular positioning groove, thereby reducing friction, making it easier to manually drive the rotary adjustment member.

[0014] Furthermore, one end of the lever abuts against the actuating curved surface, the middle part is rotatably connected to the upper baking tray assembly, and the other end is connected to the support member; or, one end of the lever is rotatably connected to the upper baking tray assembly, the middle part abuts against the actuating curved surface, and the other end is connected to the support member.

[0015] By adopting the above technical solution and utilizing the amplifying effect of the lever principle, the height adjustment of the support member within a larger range can be achieved through a smaller height change of the actuating curved surface, thereby reducing the requirement for the height change of the actuating curved surface.

[0016] Furthermore, the rotary adjustment member includes a turntable and a knob, the turntable is rotatably connected to the upper baking tray assembly, the top surface of the upper baking tray assembly is provided with a through hole, the knob is provided on the top surface of the upper baking tray assembly and connected to the turntable through the through hole, and the knob rotates synchronously with the turntable; or, the rotary adjustment member includes a turntable and a knob, the turntable is rotatably connected to the upper baking tray assembly, the top of the turntable is provided with a first magnetic component, the knob is provided on the top surface of the upper baking tray assembly, the knob is provided with a second magnetic component, the second magnetic component is attracted to the first magnetic component in the air, and the knob rotates synchronously with the turntable.

[0017] By adopting the above-mentioned technical solution, the synchronous rotation of the knob and the turntable facilitates the rotation of the lever and thereby pushes the support member out of the upper baking tray assembly to adjust the height of the upper baking tray assembly. The knob and the turntable are directly connected via a through hole, thereby improving the stability of the connection between the knob and the turntable and avoiding the situation where the knob and the turntable cannot rotate synchronously. The knob and the turntable are magnetically attracted to each other in the air by the first magnetic attraction member and the second magnetic attraction member, thereby avoiding the opening of a through hole on the top surface of the upper baking tray assembly and reducing the processing cost of the upper baking tray assembly. When no through hole is provided, the accumulation of a lot of dust on the upper baking tray assembly is avoided. At the same time, there is no need to consider the waterproofing problem on the upper side of the upper baking tray assembly, which facilitates the cleaning of the upper baking tray assembly.

[0018] Furthermore, the lever and / or the support member is provided with a first elastic member for keeping the lever pressed against the actuating curved surface.

[0019] Using the above-mentioned technical solution, a first elastic member is installed on the lever or the support member, and the end of the lever close to the turntable remains in contact with the actuating surface to prevent the lever from separating from the actuating surface and affecting the subsequent height adjustment of the upper baking tray assembly; or a first elastic member is installed on both the lever and the support member to improve the stability of the contact between the lever and the actuating surface.

[0020] Furthermore, the support member includes a pair of push rods and a connecting rod connected between the paired push rods, the lever is pressed against the connecting rod to achieve connection, and a second elastic member is provided on the support member to keep the support member in an upward trend.

[0021] By adopting the above-mentioned technical solution, the paired push rods increase the support points of the support member on the lower baking tray assembly, thereby improving the stability of the upper baking tray assembly after height adjustment. The connecting rod connects the paired push rods so that the same pair of push rods are supported on the lower baking tray assembly at the same time, avoiding the situation where the upper baking tray assembly is tilted due to the same pair of push rods supporting one in front and the other in the back; the lever abuts on the connecting rod, thereby increasing the contact area between the lever and the connecting rod, thereby avoiding the lever and the support member from being disengaged; the second elastic member is installed between the push rod and the upper baking tray assembly and abuts the push rod upward, and the push rod drives the connecting rod to abut the lever in the opposite direction, so that the end of the lever away from the connecting rod abuts on the actuating curved surface. The second elastic member improves the stability of the abutment between the lever and the actuating curved surface, thereby improving the reliability of the height adjustment of the upper baking tray assembly; and avoids the upper baking tray assembly from automatically resetting when not operated after adjustment.

[0022] Furthermore, the upper baking tray assembly includes a first upper cover and a first lower cover, the first upper cover and the first lower cover are connected, the first lower cover is provided with a through hole for the support member to pass through, and the first lower cover is provided with an annular rib at the upper end edge of the through hole, and the annular rib increases the length of the through hole to provide a guide for the up and down movement of the support member.

[0023] By adopting the above-mentioned technical solution, during the rising process of the upper baking tray assembly, the lever abuts the support member, causing the support member to descend relative to the first upper cover. During the descending process, the support member moves downward in the through-hole, and the annular ribs on the upper end edge of the through-hole increase the length of the through-hole, thereby improving the stability of the movement of the support member during the rising and falling process. At the same time, the increased length of the through-hole provides a guiding effect for the support member, thereby preventing the support member from slipping out of the through-hole during the lifting process and affecting the height adjustment of the upper baking tray assembly.

[0024] Furthermore, the rotation adjustment member includes a turntable rotatably connected to the upper baking tray assembly, the turntable is provided with a first convex rib protruding upward, the first convex rib extends along the circumference of the turntable, and the actuating curved surface is provided on the top surface of the first convex rib; or, the rotation adjustment member includes a turntable rotatably connected to the upper baking tray assembly, the turntable is provided with a boss, the outer periphery of the boss is provided with an annular step surface, and the actuating curved surface is provided on the annular step surface; or, the rotation adjustment member includes a turntable rotatably connected to the upper baking tray assembly, the outer periphery of the turntable is provided with a transversely protruding second convex rib, and the actuating curved surface is provided on the upper surface or lower surface of the second convex rib; or, the rotation adjustment member includes a turntable rotatably connected to the upper baking tray assembly, the outer peripheral side surface of the turntable is provided with a guide groove with varying heights, the actuating curved surface is provided on the upper side or lower side surface of the guide groove, and the lever is inserted into the guide groove.

[0025] By adopting the above-mentioned technical solution, the actuating surface can be formed in a variety of forms, and the corresponding actuating surface can be selected according to the actual processing conditions to improve the stability of the abutment between the actuating surface and the lever.

[0038] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0039] like Figure 1 As shown, the utility model provides a grilling machine, comprising an upper grilling tray assembly 1 and a lower grilling tray assembly 2. The upper grilling tray assembly 1 is provided with a support adjustment assembly 3, which is used to adjust the height of the upper grilling tray assembly 1 so that the cooking space between the lower side of the upper grilling tray assembly 1 and the upward side of the lower grilling tray assembly 2 can adapt to foods of different thicknesses to be grilled.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, specifically, the support adjustment assembly 3 includes a rotary adjustment member 31, a lever 32 and a support member 33. The rotary adjustment member 31 is installed on the upper baking tray assembly 1 and rotates horizontally relative to the upper baking tray assembly 1. The rotary adjustment member 31 is provided with an actuating curved surface 311. The actuating curved surface 311 changes in height in the circumferential direction of the rotary adjustment member 31. The lever 32 is rotatably connected to the upper baking tray assembly 1. The lever 32 abuts on the actuating curved surface 311. The support member 33 is installed on the upper baking tray assembly 1. The support member 33 can be lowered relative to the upper baking tray assembly 1 and supported on the lower baking tray assembly 2. More specifically, one end of the lever 32 abuts the actuating curved surface 311, and the other end abuts the support member 33. The middle portion of lever 32 is rotatably connected to the upper grill assembly 1. When the rotary adjustment member 31 is rotated, the end of lever 32 abutting against the actuating curved surface 311 rises with the rotation of the rotary adjustment member 31. The other end of lever 32 then abuts against the support member 33 downward, causing the support member 33 to descend and extend out of the upper grill assembly 1 before abutting against the lower grill assembly 2, thereby supporting the upper grill assembly 1. This allows the height of the cooking space between the upper and lower grill assemblies 1 and 2 to be adjusted, facilitating grilling of foods of varying thicknesses within the cooking space. After the height is adjusted, the upper grill assembly 1 is stably supported by the support member 33, preventing it from accidentally dropping. Through the amplifying effect of the lever principle, a relatively small height change of the actuating curved surface 311 allows for a greater height adjustment of the upper grill assembly 1. This reduces the height change requirement of the actuating curved surface 311 and increases the height adjustment range of the upper grill assembly 1, allowing the grill to accommodate a wider range of foods of varying thicknesses and further improving the grill's suitability for various thicknesses.

[0041] In order to improve the stability of the upper baking tray assembly 1 after it is raised, Figure 3 and Figure 4As shown, the actuating curved surface 311 is provided with self-locking planes 314 at different heights. The lever 32 rotates to the self-locking plane 314 and abuts against the self-locking plane 314. Without the action of external forces, the lever 32 stably abuts against the self-locking plane 314, so that the support member 33 remains in its current position, thereby improving the stability of the upper grilling plate assembly 1 after it is raised. The self-locking planes 314 are provided at different heights to form multiple gears of different heights. When dealing with a wider variety of foods and thicknesses, the upper grilling plate assembly 1 can be raised to a suitable height, which is more applicable. Moreover, the upper grilling plate assembly 1 can be adjusted to a more suitable height to ensure that the heating efficiency of the upper grilling plate assembly 1 is not affected.

[0042] In order to further improve the stability of the upper baking tray assembly 1, as Figure 2 and Figure 3 As shown, multiple levers 32 are provided. In this embodiment, there are two levers 32, which are distributed circumferentially around the rotary adjustment member 31. Two actuating surfaces 311 are also provided, and the two actuating surfaces 311 abut against the two levers 32 in a one-to-one manner. The two actuating surfaces 311 are separated from each other. The two levers 32 abut against the support member 33 in the circumferential direction to support the upper baking tray assembly 1 and improve the stability of the upper baking tray assembly 1. A limiting rib 315 is installed at the rear end of the actuating surface 311. The limiting rib 315 prevents the lever 32 from disengaging from the actuating surface 311 when sliding to the rear end of the actuating surface 311, thereby preventing the upper baking tray assembly 1 from suddenly falling after reaching its highest point. In another embodiment, a plurality of levers 32 are distributed circumferentially around the rotary adjustment member 31, and a plurality of actuating surfaces 311 are also provided on the rotary adjustment member 31. The plurality of actuating surfaces 311 are in one-to-one contact with the lever 32, and the plurality of actuating surfaces 311 are connected end to end to form an annular surface. When adjusting the height of the upper baking tray assembly 1, the lever 32 rises and falls back and forth along the annular surface with the continuous rotation of the turntable 313. The height of the upper baking tray assembly 1 can be adjusted by forward or reverse rotation, thereby improving the degree of freedom of height adjustment of the upper baking tray assembly 1.

[0043] In another embodiment, Figure 2 As shown, the upper baking tray assembly 1 includes a first upper cover 11 and a first lower cover 12, and the first upper cover 11 and the first lower cover 12 are connected. A more specific connection method can be a detachable fixed connection through screws, etc., so that the support adjustment assembly 3 is hidden and installed between the first upper cover 11 and the first lower cover 12, and the first upper cover 11 and the first lower cover 12 are not easily disengaged; the lever 32 can be hinged on the lower side of the first upper cover 11, or on the upper side of the first lower cover 12; when the rotary adjustment member 31 rotates, the lever 32 rotates along the hinge axis.

[0044] In this embodiment, if Figures 5 to 7 As shown, in order to improve the stability of the installation of the rotation adjustment member 31, as shown Figure 6As shown, the upper side of the first lower cover 12 is provided with a rotating shaft 123 and an annular positioning groove 124, and the rotating shaft 123 extends upward. Figure 6 and Figure 7 As shown, the bottom end of the rotary adjustment member 31 is provided with an axial hole 3131 and a positioning ring body 3132, the rotating shaft 123 cooperates with the axial hole 3131, and the positioning ring body 3132 cooperates with the annular positioning groove 124, so as to stably install the rotary adjustment member 31. In addition, a protrusion 3133 is provided on the bottom end surface of the positioning ring body 3132, and the protrusion 3133 contacts the annular positioning groove 124, reducing the contact area between the positioning ring body 3132 and the annular positioning groove 124, thereby reducing the friction when the rotary adjustment member 31 rotates.

[0045] When the lever 32 is in the upright position, the lever 32 is in the upright position, and the lever 32 is in the upright position, so that the lever 32 can be lifted up and down to the left and right of the support 33. When the lever 32 is in the upright position, the lever 32 is lifted up and down, so that the lever 32 can be lifted up and down to the left and right of the support 33.

[0046] In another embodiment, if Figure 2 and Figure 3 As shown, the rotary adjustment member 31 includes a turntable 313 and a knob 312, and the turntable 313 is rotatably connected to the upper baking tray assembly 1. The top surface of the upper baking tray assembly 1 is provided with a through hole 111, and the knob 312 is provided on the top surface of the upper baking tray assembly 1. After the knob 312 extends into the through hole 111, it is connected to the turntable 313 so that the turntable 313 can rotate synchronously with the knob 312, and the dynamic curved surface 311 is located on the turntable 313. When the height of the upper baking tray assembly 1 needs to be adjusted, the turntable 313 is driven to rotate synchronously when the knob 312 is rotated, so that the lever 32 moves upward along the curved surface curvature of the actuating curved surface 311 as the turntable 313 rotates, and the turntable 313 is driven to rotate by the knob 312, thereby improving the convenience of height adjustment of the upper baking tray assembly 1.

[0047] In order to facilitate the installation of the turntable 313 and the knob 312, a first magnetic member is provided at the top of the turntable 313, and the knob 312 is provided on the top surface of the upper baking tray assembly 1. The knob 312 is provided with a second magnetic member. The second magnetic member and the first magnetic member are attracted to each other in the air with the first upper cover 11 in between, so that the knob 312 and the turntable 313 are fixed circumferentially after being attracted, which facilitates the synchronous rotation of the knob 312 and the turntable 313. At this time, there is no need to open a through hole 111 on the top surface of the upper baking tray assembly 1, which reduces the processing cost of the upper baking tray assembly 1 and improves the convenience of installing the turntable 313 and the knob 312.

[0048] The state of the upper baking tray assembly 1 when it is not lifted is as follows Figure 8 As shown, when the height of the upper baking tray assembly 1 needs to be adjusted, the knob 312 drives the turntable 313 to rotate, so that the actuating curved surface 311 rotates relative to the lever 32, and the actuating curved surface 311 lifts one end of the lever 32 upward, and the middle part of the lever 32 rotates relative to the upper baking tray assembly 1, so that the other end of the lever 32 abuts downward against the support member 33, and the support member 33 descends and extends to support the lower baking tray assembly 2 to improve the stability of the upper baking tray assembly 1, thereby adjusting the height of the upper baking tray assembly 1. The state after adjustment is shown in FIG. Figure 9 As shown, the heights of the upper baking tray assembly 1 and the lower baking tray assembly 2 are suitable for foods of different thicknesses.

[0049] In order to keep the lever 32 in contact with the actuating curved surface 311, Figure 3 As shown, the lever 32 is provided with a first elastic member 333. One side of the first elastic member 333 is located at the end of the lever 32 away from the actuating curved surface 311, and the other side of the first elastic member 333 is located on the upper side of the first lower cover. The first elastic member 333 abuts the lever 32 from below, so that the other end of the lever 32 remains in contact with the actuating curved surface 311, preventing the lever 32 from separating from the actuating curved surface 311 and affecting the height adjustment of the upper grilling tray assembly 1. The first elastic member 333 can also be disposed between the support member 33 and the upper grilling tray assembly 1. The first elastic member 333 maintains a tendency to push the support member 33 upward, so that the support member 33 abuts the lever 32 upward.

[0050] In another embodiment, Figure 3As shown, the support member 33 is provided with a second elastic member 334 to keep the support member 33 in an upward trend. The support member 33 includes a pair of top rods 331 and a connecting rod 332 connected between the pair of top rods 331. The top rods 331 are installed in pairs, and the connecting rod 332 is connected between the pair of top rods 331. The lever 32 abuts on the connecting rod 332 to increase the contact area between the lever 32 and the support member 33 and ensure the stability of the abutment between the lever 32 and the support member 33. When the lever 32 abuts the connecting rod 332 downward, the connecting rod 332 acts synchronously on the pair of top rods 331, so that The paired push rods 331 move downward synchronously and then abut against the lower baking tray assembly 2, thereby preventing the upper baking tray assembly 1 from tilting during the height adjustment process. The second elastic member 334 is connected between the push rods 331 and the upper baking tray assembly 1. The second elastic member 334 enables the push rods 331 to maintain an upward trend, thereby keeping the other end of the lever 32 in abutment with the actuating curved surface 311; at the same time, the stability of the abutment between the lever 32 and the actuating curved surface 311 is improved, thereby improving the reliability of the height adjustment of the upper baking tray assembly 1; and preventing the upper baking tray assembly 1 from automatically resetting when no operation is performed after adjustment.

[0051] In order to improve the stability of the support member 33, as Figure 2 and Figure 5 As shown, the first lower cover 12 is provided with a through hole 121 for the support member 33 to pass through, and the upper side surface of the first upper cover 11 is provided with an annular rib 122, which is located at the edge of the upper end of the through hole 121. The length of the through hole 121 is increased by the annular rib 122, which provides guidance for the up and down movement of the support member 33, and the increased through hole 121 prevents the support member 33 from completely separating from the first lower cover, thereby improving the stability of the support member 33.

[0052] like Figure 4As shown, the rotary adjustment member 31 includes a turntable 313 rotatably connected to the upper baking tray assembly 1. Regarding the formation of the actuating surface 311, it can be formed in the following manner: the turntable 313 is provided with a first convex rib protruding upward, the first convex rib extends along the circumference of the turntable 313, and the top surface of the first convex rib has a height change in the circumferential direction, and the actuating surface 311 is provided on the top surface of the first convex rib; or, the turntable 313 is provided with a boss, the outer periphery of the boss is provided with an annular step surface, the annular step surface has a height change in the circumferential direction, and the actuating surface 311 is provided on the annular step surface; or, the outer periphery of the turntable 313 is provided with a transversely protruding second convex rib, the upper and lower surfaces of the second convex rib both have a height change in the circumferential direction, and the actuating surface 311 is provided on the lower surface of the second convex rib; the actuating surface 311 can also be provided on the upper surface of the second convex rib. In this case, the middle part of the lever 32 When the lever 32 is in the unlocked position, the lever 32 is in the unlocked position, and the lock 313 is in the unlocked position, so that the lock 313 is unlocked and the lock 313 is unlocked.

[0053] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
