Description

Technical Field

[0001] The present invention belongs to the technical field of electronic display screens, and in particular relates to an electronic display screen composed of multiple screens. Background Art

[0002] Electronic display screens can display changing numbers, text, graphics and images; they can be used not only in indoor environments but also in outdoor environments, and have advantages that projectors, TV walls and LCD screens cannot match. Electronic display screens can generally be divided into two categories:

[0003] One explanation is that electronic displays are made up of tens to hundreds of thousands of evenly spaced semiconductor light-emitting diode pixels. Different materials can be used to create LED pixels of varying colors. Currently, red, green, and yellow are the most widely used. However, blue and pure green LEDs have already reached practical application.

[0004] Another explanation is that an electronic display screen is composed of several display units (unit display panels or unit display cabinets) that can be combined and spliced together, and an appropriate controller (main control board or control system) is used to control the display of the electronic display screen. Therefore, a variety of display panels (or unit cabinets) with controllers using different control technologies can be combined to form a variety of LED screens to meet the needs of different environments and different display requirements.

[0005] At present, for the assembly of electronic display screens, the assembled parts generally include unit display panels, an outer frame, a magnet block with studs, a keel, and a power supply. The actual assembly method is: first assemble and shape the outer frame, then evenly lay the unit display panels within the range surrounded by the outer frame, and screw the magnet block with studs to the back of the unit display panels. Then, install the keel equidistantly inside the outer frame. The keel can be magnetically connected to the magnet block with studs. Therefore, after fixing the keel to the outer frame, use the magnet block with studs to magnetically connect the unit display panels to the keel. Finally, adjust the multiple unit display panels to a neat state and install the power supply.

[0006] From the above description of the installation method of the electronic display screen in the prior art, it can be seen that the main technical problem is that the prior art uses magnetic attraction to achieve the connection and fixation of the unit display panel and the outer frame. After the unit display panel is magnetically connected to the keel, the multiple unit display panels are still in an uneven state, so the position of the unit display panel needs to be finely adjusted. This requires that the connection surface between the magnet block and the keel needs to be flat, otherwise the position of the unit display panel after the magnetic connection cannot be finely adjusted, which leads to the problem that the connection method between the unit display panel and the keel is not strong enough. Summary of the Invention

[0007] The purpose of the present invention is to solve the problem in the background art that the current connection method between the unit display panel and the keel is not firm enough, and to propose an electronic display screen with multiple screens.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A multi-screen electronic display screen comprises a display screen body, wherein the display screen body comprises a plurality of display units, wherein the display units comprise an electronic screen, a fixed frame arranged on the back of the electronic screen, and a latching mechanism for latching the electronic screen onto the fixed frame, wherein the latching mechanism comprises a spring sheet fixed to the back of the electronic screen, a quadrangular pyramid block fixed to the top of one side of the spring sheet, a latching plate fixedly connected to the fixed frame and abutting against one side of the spring sheet, and a latching inclined surface provided at the top of the latching plate near the edge of the spring sheet, wherein the inclination of the latching inclined surface is equal to the inclination of the bottom inclined surface of the quadrangular pyramid block; and the latching plate is further provided with an adjustment mechanism for adjusting the relative position of the quadrangular pyramid block and the latching inclined surface.

[0010] As a further description of the above technical solution: the edge of the electronic screen is aligned with the edge of the fixed frame. In this way, after multiple display units are assembled and spliced together, the two adjacent fixed frames can be pressed against each other, thereby achieving the purpose of reducing the pressure between the two adjacent electronic screens and avoiding damage to the edge of the electronic screen due to squeezing; by setting a locking mechanism, the action of the spring sheet is used to keep the inclined surface at the bottom of the quadrangular pyramid block and the locking inclined surface in a state of contact, thereby realizing the connection between the electronic screen and the fixed frame. Compared with the traditional magnetic connection method, the snap connection method in this solution will not have the situation of relative sliding between the electronic screen and the fixed frame, and has better stability and firmness.

[0011] The adjusting mechanism includes a fixed plate fixed on the locking plate, a rotating shaft arranged above the quadrangular block and rotatably connected to the fixed plate, and a pressure plate and a push plate fixed to the rotating shaft and radially arranged along the rotating shaft. The pressure plate and push plate are respectively arranged on both sides of the quadrangular block, and the extension directions of the pressure plate and the push plate are opposite. A buffer groove that can accommodate the pressure plate is provided on the top of the spring sheet, and a second hemispherical head is fixed to a side of the push plate close to the pressure plate.

[0012] As a further description of the above technical solution: due to the squeezing effect of the pressure plate on the tetrahedral block, the inclined surface at the bottom of the tetrahedral block and the locking inclined surface can maintain a stable contact state, which can avoid the situation where the inclined surface at the bottom of the tetrahedral block and the locking inclined surface are released from the contact state in an accidental situation, and also significantly enhances the stability and reliability of the contact between the inclined surface at the bottom of the tetrahedral block and the locking inclined surface.

[0013] A sleeve is fixed on the fixed plate, the rotating shaft passes through the sleeve, and a torsion spring is arranged inside the sleeve. One end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the sleeve. One end of the rotating shaft is fixedly connected to a toggle rod arranged radially along the rotating shaft.

[0014] As a further description of the above technical solution: when the user rotates the rotating shaft, due to the presence of the torsion spring, the rotating shaft will have a certain rotational force. When the user no longer applies torsion to the rotating shaft, the rotating shaft will quickly reset under the action of the torsion spring.

[0015] An alignment mechanism is also provided between the electronic screen and the fixed frame. The alignment mechanism includes an alignment column fixed to the fixed frame and a plug-in column fixed to the back of the electronic screen. An alignment hole is opened inside the alignment column along its axial direction. The plug-in column passes through the alignment hole, and a first hemispherical head is formed at the top of the plug-in column.

[0016] As a further description of the above technical solution: by providing an alignment mechanism and utilizing the plug-in cooperation between the plug-in columns and the alignment holes, the electronic screen and the fixed frame can be quickly aligned, thereby improving the actual installation efficiency.

[0017] The locking plate is fixedly connected to the fixing frame via a connecting block. An operating space is formed between the locking plate and the fixing frame. The toggle rod and the sleeve are both located inside the operating space.

[0018] A plurality of the display units are supported and combined by a supporting assembly to form a display screen body. The supporting assembly includes two supporting mechanisms and a connecting mechanism for connecting the two supporting mechanisms.

[0019] The support mechanism includes a round rod and two right-angle plates symmetrically arranged on both sides of the axial direction of the round rod. The right-angle plates are movably connected to the round rod through an elastic telescopic component. The elastic telescopic component can be extended and retracted along the radial direction of the round rod. A square hole is opened on the fixed frame, and the support mechanism passes through the square hole. The two right-angle plates are supported by the elastic telescopic component and respectively rest on the two obliquely symmetrical corners of the square hole.

[0020] As a further description of the above technical solution: by setting the supporting mechanism into a structure of a round rod and two right-angle plates, and elastically connecting the round rod and the right-angle plates, since the length and width of each square hole are consistent, after the supporting mechanism is passed through the square hole, the two right-angle plates can be supported by the elastic telescopic component and respectively rest against the two obliquely symmetrical corner positions of the square hole, so as to achieve the purpose of aligning each fixed frame, avoiding the unevenness of the front side of the entire display screen body used for displaying the picture, and since the round rod and the right-angle plates are elastically connected, it is also convenient for users to pass the supporting mechanism through the square hole, and the operation is simple.

[0021] The elastic telescopic component includes a plurality of first blind holes opened along the axial direction of the round rod and a gas spring installed in the first blind holes, and one end of the gas spring is fixedly connected to the right-angle plate.

[0022] As a further description of the above technical solution: the gas spring is an existing technology and is easy to use. Moreover, since the gas spring can elastically expand and contract in a linear direction, it will not cause relative movement between the round rod and the right-angle plate in the axial direction.

[0023] The connecting mechanism includes a long plate and two end heads fixed at both ends of the long plate. A plurality of reserved holes are provided on the long plate. A second blind hole is provided at one end of the end head, and a through hole connected to the second blind hole is provided at the other end of the end head. A threaded hole is provided at one end of the round rod, and one end of the round rod is inserted into the inside of the second blind hole. The bolt passes through the through hole and is threadedly connected to the inside of the threaded hole.

[0024] The other end of the round rod is fixedly connected with a positioning plate, and the opening position of the square hole close to the outer side surface of the fixing frame is provided with a positioning groove, and the positioning plate and the positioning groove are matched.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, a locking mechanism is provided and the spring sheet is used to keep the inclined surface at the bottom of the quadrangular pyramid block in contact with the locking inclined surface, thereby enabling the connection between the electronic screen and the fixed frame. Compared with the traditional magnetic connection method, the locking connection method in this solution will not cause relative sliding between the electronic screen and the fixed frame, and has better stability and firmness.

[0027] 2. In the present invention, due to the squeezing effect of the pressure plate on the tetrahedral block, the inclined surface at the bottom of the tetrahedral block and the locking inclined surface can maintain a stable state of contact, which can avoid the situation where the inclined surface at the bottom of the tetrahedral block and the locking inclined surface are released from the contact state under unexpected circumstances, that is, the stability and reliability of the contact between the inclined surface at the bottom of the tetrahedral block and the locking inclined surface are significantly enhanced; at the same time, due to the rotatable setting of the second hemispherical head, it is also convenient to disassemble the electronic screen.

[0028] 3. In the present invention, the support mechanism is set to a structure of a round rod and two right-angle plates, and the round rod and the right-angle plates are elastically connected. Since the length and width of each square hole are consistent, after the support mechanism is passed through the square hole, the two right-angle plates can be supported by the elastic telescopic component and respectively rest against the two obliquely symmetrical corners of the square hole, so as to achieve the purpose of aligning each fixed frame and avoid the front of the entire display screen body used for displaying the picture from being uneven. Moreover, since the round rod and the right-angle plates are elastically connected, it is also convenient for users to pass the support mechanism through the square hole, and the operation is simple.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] The present invention provides an electronic display screen with multiple screens, such as Figure 1 As shown, the multi-screen electronic display screen includes a display screen body 100 and a support assembly 200. The display screen body 100 includes a plurality of display units 110. The support assembly 200 is used to assemble and connect the plurality of display units 110 together to form the display screen body 100. The display screen body 100 can be used to display numbers, images, etc., and its common use is as a billboard.

[0043] like Figure 3As shown, the display unit 110 includes an electronic screen 111, a fixed frame 112 arranged on the back of the electronic screen 111, and a locking mechanism 113 for locking the electronic screen 111 to the fixed frame 112, wherein the electronic screen 111 is a square structure, and the length and width of the fixed frame 112 are consistent with the length and width of the electronic screen 111. After the electronic screen 111 and the fixed frame 112 are connected together by the locking mechanism 113, the edge of the electronic screen 111 is aligned with the edge of the fixed frame 112. In this way, after multiple display units 110 are assembled and spliced together, two adjacent fixed frames 112 can be pressed against each other, thereby achieving the purpose of reducing the pressure between the two adjacent electronic screens 111 and avoiding damage to the edges of the electronic screens 111 due to squeezing.

[0044] like Figure 6 and 7 As shown, the locking mechanism 113 includes a spring piece 1131 fixed to the back of the electronic screen 111, a quadrangular block 1134 fixed to the top of one side of the spring piece 1131, a locking plate 1133 fixedly connected to the fixed frame 112 and abutting against one side of the spring piece 1131, and a locking slope 1136 opened at the top of the locking plate 1133 near the edge of the spring piece 1131. The spring piece 1131 and the locking plate 1133 are both perpendicular to the back of the electronic screen 111. When locked, the slope at the bottom of the quadrangular block 1134 is abutted against the locking slope 1136 on the locking plate 1133, and the spring piece 1131 is now in the position as shown in the figure. Figure 6 and 7 In the state shown, that is, the state without bending, the spring sheet 1131 can keep the inclined surface at the bottom of the quadrangular pyramid block 1134 in contact with the locking inclined surface 1136 on the locking plate 1133, and the inclination of the locking inclined surface 1136 is equal to the inclination of the inclined surface at the bottom of the quadrangular pyramid block 1134.

[0045] This technical solution sets a locking mechanism 113 and uses the action of the spring piece 1131 to keep the inclined surface at the bottom of the quadrangular pyramid block 1134 in contact with the locking inclined surface 1136, thereby realizing the connection between the electronic screen 111 and the fixed frame 112. Compared with the traditional magnetic connection method, the locking connection method in this solution will not cause relative sliding between the electronic screen 111 and the fixed frame 112, and has better stability and firmness. In actual operation, it is only necessary to align the positions of the spring piece 1131 and the locking plate 1133, and then directly push up the electronic screen 111. When the top of the quadrangular pyramid block 1134 contacts an edge position of the bottom of the locking plate 1133, since the top of the quadrangular pyramid block 1134 is a slope, the vertical upward force of the quadrangular pyramid block 1134 will be decomposed into a continuous upward force The spring sheet 1131 is in a bent state at this time, and then when the spring sheet 1131 is bent to a certain extent, the quadrangular block 1134 can slide upward along the side of the locking plate 1133 until the quadrangular block 1134 moves to one side of the locking inclined surface 1136. The elastic force generated by the bending of the spring sheet 1131 will push the quadrangular block 1134 back to its original position, that is, push the inclined surface at the bottom of the quadrangular block 1134 to fit together with the locking inclined surface 1136, completing the locking connection between the electronic screen 111 and the fixed frame 112; the locking plate 1133 is also provided with an adjustment mechanism 115 for adjusting the relative position of the quadrangular block 1134 and the locking inclined surface 1136.

[0046] like Figures 6 to 8 As shown, the adjustment mechanism 115 includes a fixed plate 1151 fixed on the locking plate 1133, a rotating shaft 1152 arranged above the quadrangular block 1134 and rotatably connected to the fixed plate 1151, and a pressure plate 1153 and a push plate 1154 fixed to the rotating shaft 1152 and arranged radially along the rotating shaft 1152. The pressure plate 1153 and the push plate 1154 are respectively arranged on both sides of the quadrangular block 1134, and the extension directions of the pressure plate 1153 and the push plate 1154 are opposite. The extension direction referred to here refers to the radial direction along the rotating shaft 1152. Therefore, the opposite extension directions of the pressure plate 1153 and the push plate 1154 mean that the pressure plate 1153 extends to one side along the radial direction of the rotating shaft 1152, while the push plate 1154 extends to the other side along the radial direction of the rotating shaft 1152, as shown in FIG. Figures 6 to 8 As shown, the pressure plate 1153 extends downward, the push plate 1154 extends upward, the top of the spring sheet 1131 is provided with a buffer groove 1135 that can accommodate the pressure plate 1153, and the second hemispherical head 1155 is fixedly connected to the side of the push plate 1154 close to the pressure plate 1153.

[0047] The cam 1136 is pressed against the bottom of the truncated plate 1134 and the cam 1137 is pressed against the bottom of the truncated plate 1134. The cam 1136 is pressed against the bottom of the truncated plate 1134 and the cam 1137 is pressed against the bottom of the truncated plate 1134. In order to achieve the purpose of disassembling the electronic screen 111, directly rotate the rotating shaft 1152, and the pressure plate 1153 will gradually turn from downward to upward, and the push plate 1154 that was originally facing upward will also gradually turn downward. During this process, on the one hand, the squeezing and blocking effect of the pressure plate 1153 on the quadrangular block 1134 disappears. On the other hand, in the process of the push plate 1154 gradually turning downward, the hemispherical surface of the second hemispherical head 1155 will first contact the inclined surface on the side of the quadrangular block 1134, and then push the quadrangular block 1134 to move gradually to the left until the inclined surface at the bottom of the quadrangular block 1134 is released from the fitting with the locking inclined surface 1136. At this time, the locking relationship between the quadrangular block 1134 and the locking plate 1133 is released, and then the electronic screen 111 can be quickly removed.

[0048] like Figure 8 As shown, a sleeve 1157 is fixed on the fixed plate 1151, the rotating shaft 1152 passes through the sleeve 1157, and a torsion spring 1158 is arranged inside the sleeve 1157, one end of the torsion spring 1158 is fixedly connected to the rotating shaft 1152, and the other end is fixedly connected to the sleeve 1157, and one end of the rotating shaft 1152 is fixedly connected to a toggle rod 1156 arranged radially along the rotating shaft 1152, and the toggle rod 1156 can enable the user to rotate the rotating shaft 1152 more effortlessly;.

[0049] like Figures 3 to 5As shown, four alignment mechanisms 114 are further provided between the electronic screen 111 and the fixed frame 112. The four alignment mechanisms 114 are respectively arranged at the four corner positions inside the fixed frame 112. The alignment mechanism 114 includes an alignment column 1141 fixed to the fixed frame 112 and a plug-in column 1143 fixed to the back of the electronic screen 111. The interior of the alignment column 1141 is provided with an alignment hole 1142 along its axial direction. The plug-in column 1143 passes through the alignment hole 1142, and a first hemispherical head 1144 is formed on the top of the plug-in column 1143. The hemispherical surface of the first hemispherical head 1144 has the effect of reducing the cross-sectional diameter of the top surface of the plug-in column 1143, which can facilitate the plug-in column 1143 to be quickly plugged into the interior of the alignment hole 1142; through the provided alignment mechanism 114, the plug-in cooperation of the plug-in column 1143 and the alignment hole 1142 is utilized, so that the electronic screen 111 and the fixed frame 112 can be quickly aligned, thereby improving the actual installation efficiency.

[0050] The locking plate 1133 is fixedly connected to the fixed frame 112 through the connecting block 1132. An operating space is formed between the locking plate 1133 and the fixed frame 112. The toggle rod 1156 and the sleeve 1157 are both located inside the operating space, providing sufficient space for the user to operate the toggle rod 1156.

[0051] like Figure 2 As shown, several display units 110 are supported and combined by a support assembly 200 to form a display screen body 100 . The support assembly 200 includes two support mechanisms 210 and a connection mechanism 220 for connecting the two support mechanisms 210 .

[0052] like Figure 2 、 Figure 9 、 Figure 10 and Figure 11As shown, the support mechanism 210 includes a round rod 211 and two right-angled plates 212 symmetrically arranged on both sides of the axial direction of the round rod 211. The axial direction of the right-angled plates 212 is parallel to the axial direction of the round rod 211. The right-angled plates 212 are movably connected to the round rod 211 through an elastic telescopic component. The elastic telescopic component can be extended and retracted along the radial direction of the round rod 211. A square hole 1121 is provided on the fixed frame 112. The support mechanism 210 passes through the square hole 1121. The two right-angled plates 212 are respectively abutted against the two obliquely symmetrical corner positions of the square hole 1121 under the support of the elastic telescopic component. By setting the support mechanism 210 as a round rod 211 with two straight The structure of the angle plate 212 makes the round rod 211 and the right-angle plate 212 elastically connected. Since the length and width of each square hole 1121 are consistent, after the support mechanism 210 passes through the square hole 1121, the two right-angle plates 212 can be supported by the elastic telescopic component and respectively rest against the two obliquely symmetrical corner positions of the square hole 1121, so as to achieve the purpose of aligning each fixed frame 112, avoiding the front of the entire display screen body 100 used for displaying the picture from being uneven, and since the round rod 211 and the right-angle plate 212 are elastically connected, it is also convenient for the user to pass the support mechanism 210 through the square hole 1121, and the operation is simple.

[0053] The elastic telescopic component includes a plurality of first blind holes 2111 opened along the axial direction of the round rod 211 and a gas spring 214 installed in the first blind hole 2111. One end of the gas spring 214 is fixedly connected to the right-angle plate 212. The gas spring 214 is an existing technology and is easy to use. Moreover, since the gas spring 214 can be elastically expanded and contracted in a linear direction, it will not cause relative movement between the round rod 211 and the right-angle plate 212 in the axial direction.

[0054] like Figure 1 、 Figure 2 、 Figure 10 and Figure 11 As shown, the connecting mechanism 220 includes a long plate 221 and two end heads 222 fixed at both ends of the long plate 221. A number of reserved holes 2211 are provided on the long plate 221. The reserved holes 2211 can be used to cooperate with bolts and other structures to connect the long plate 221 with other structures. A second blind hole 2221 is provided at one end of the end head 222, and a through hole 2222 connected to the second blind hole 2221 is provided at the other end of the end head 222. A threaded hole 2112 is provided at one end of the round rod 211, and one end of the round rod 211 is inserted into the inside of the second blind hole 2221. The bolt 223 passes through the through hole 2222 and is threadedly connected to the inside of the threaded hole 2112.

[0055] like Figure 3As shown, the other end of the round rod 211 is fixedly connected to a positioning plate 213, and a positioning groove 1122 is provided at the opening position of the square hole 1121 near the outer side of the fixing frame 112. The thickness of the positioning plate 213 is the same as the groove depth of the positioning groove 1122, that is, the positioning plate 213 can be completely received in the interior of the positioning groove 1122; Figure 1 In the state shown, the positioning plate 213 is completely received in the positioning groove 1122 at the top of the fixing frame 112 at the top.

[0056] Working principle: When the electronic screen 111 is actually installed, it is only necessary to align the spring piece 1131 and the positioning plate 1133, and then directly push the electronic screen 111 upward. When the top of the quadrangular block 1134 contacts an edge of the bottom of the positioning plate 1133, since the top of the quadrangular block 1134 is an inclined surface, the vertical upward force of the quadrangular block 1134 will be decomposed into a continuous upward force and a horizontal force. The horizontal force will push the quadrangular block 1134 gradually away from the positioning plate. 1133, at this time the spring piece 1131 is in a bent state, and then when the spring piece 1131 is bent to a certain extent, the quadrangular pyramid block 1134 can slide upward along the side of the locking plate 1133 until the quadrangular pyramid block 1134 moves to one side of the locking inclined surface 1136. The elastic force generated by the bending of the spring piece 1131 will push the quadrangular pyramid block 1134 back to its original position, that is, push the inclined surface at the bottom of the quadrangular pyramid block 1134 to abut against the locking inclined surface 1136, completing the locking connection between the electronic screen 111 and the fixed frame 112;

[0057] When the electronic screen 111 needs to be disassembled, first, under normal conditions, the pressing plate 1153 is in a vertical downward position and is located inside the buffer groove 1135, and the side of the pressing plate 1153 is pressed against the side of the quadrangular platform block 1134. In this state, due to the squeezing effect of the pressing plate 1153 on the quadrangular platform block 1134, the inclined surface at the bottom of the quadrangular platform block 1134 and the positioning inclined surface 1136 can maintain a stable position, which can avoid the inclined surface at the bottom of the quadrangular platform block 1134 and the positioning inclined surface 1136 from being released in an accident. In addition to the occurrence of the fitted state, the stability and reliability of the fit between the inclined surface at the bottom of the quadrangular pyramid block 1134 and the locking inclined surface 1136 are significantly enhanced; and when it is necessary to release the fit between the inclined surface at the bottom of the quadrangular pyramid block 1134 and the locking inclined surface 1136 to achieve the purpose of disassembling the electronic screen 111, the rotating shaft 1152 is directly rotated, and the pressing plate 1153 at this time will gradually turn from downward to upward, and the push plate 1154 originally facing upward will also gradually turn downward. In this process, on the one hand, the pressing plate 1153 exerts pressure on the quadrangular pyramid block 1134. 134, the squeezing and blocking effect of the push plate 1154 disappears. On the other hand, as the push plate 1154 gradually turns downward, the hemispherical surface of the second hemispherical head 1155 will first contact the inclined surface on the side of the quadrangular pyramid block 1134, and then push the quadrangular pyramid block 1134 to move gradually to the left until the inclined surface at the bottom of the quadrangular pyramid block 1134 is released from the engagement with the locking inclined surface 1136. At this time, the locking relationship between the quadrangular pyramid block 1134 and the locking plate 1133 is released, and then the electronic screen 111 can be quickly removed. In the process of the user rotating the rotating shaft 1152, the second hemispherical head 1155 will first contact the inclined surface on the side of the quadrangular pyramid block 1134, and then push the quadrangular pyramid block 1134 to move gradually to the left, until the engagement between the inclined surface at the bottom of the quadrangular pyramid block 1134 and the locking inclined surface 1136 is released. Due to the presence of the torsion spring 1158, the rotating shaft 1152 will have a certain rotational force. When the user no longer applies torsion to the rotating shaft 1152, the rotating shaft 1152 will quickly reset under the action of the torsion spring 1158; when installing the support mechanism 210, the support mechanism 210 can be held tightly so that the two right-angle plates 212 can be as close to the round rod 211 as possible. At this time, the diameter of the entire support mechanism 210 will be reduced. In this state, the user can also more conveniently and labor-savingly pass the support mechanism 210 through the square hole 1121.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
