Description
A multi-functional woodworking push saw table Technical Field
[0001] This invention relates to the field of woodworking machinery technology, and in particular to a multifunctional woodworking push saw table. Background Technology
[0002] The sliding table saw, a common type of woodworking machinery, is widely used for straight and angled cutting of wood. A traditional sliding table saw typically includes a fixed worktable, a circular saw blade positioned in the center of the worktable, and a guide mechanism for the workpiece. In actual use, operators often need to perform various types of cuts, such as parallel straight cuts, fixed-width cuts, and beveling at different angles. This requires the sliding table saw to have flexible, stable, and precise positioning and guiding functions.
[0003] Currently available woodworking sliding table saws still have several shortcomings in achieving multi-functional integration. Firstly, angle cutting largely relies on manually adjusting the backrest angle or changing angle clamps, a cumbersome process that makes it difficult to achieve quick and precise angle setting and locking, affecting processing efficiency and cutting accuracy. Secondly, conventional backrest structures are mostly fixed or have only limited linear adjustment capabilities, failing to simultaneously meet the flexible positioning needs in both width and length directions, especially when processing workpieces of different sizes, where their adaptability is poor. Furthermore, traditional worktable dimensions are fixed, lacking effective extension support when processing longer workpieces, easily leading to unstable cutting, decreased accuracy, and even operational safety hazards due to workpiece suspension. Summary of the Invention
[0004] In view of this, embodiments of the present invention provide a multifunctional woodworking push saw table to solve or improve the technical problems existing in the prior art.

The inner side of the J-shaped bracket engages with the locking bar of the first bracket, and the hook-shaped part at its bottom engages with one side of the first guide connecting bar.
[0020] The first locking knob passes through the J-shaped frame and the first bracket locking bar in sequence, and its end is in abutting contact with the V-shaped groove of the first V-shaped sliding groove bar. The first locking knob is threadedly connected to the J-shaped frame.
[0021] An angle reference ruler is horizontally and fixedly mounted on the tray frame;
[0022] An adjustable straightedge is set along the length of the workbench and is fixedly connected to the angle reference ruler.
[0023] As an improvement, the ruler backing section includes:
[0024] The second guide connecting strip is disposed at the other end of the worktable along its length and extends along the length direction;
[0025] The second V-shaped sliding groove strip is fitted onto the second guide connecting strip;
[0026] The second bracket locking bar has an inverted J-shaped structure. The inner side of its vertical arm matches the side of the second V-shaped sliding groove bar, and its top hook-shaped part engages with the upper end of the second V-shaped sliding groove bar.
[0027] The second locking knob passes through the second bracket locking bar, and its end is in abutting contact with the V-groove of the second V-shaped sliding bar. The second locking knob is threadedly connected to the second bracket locking bar.
[0028] The L-shaped fixing plate has its vertical side fixedly connected to the second bracket locking strip, and its horizontal side extends above the workbench surface.
[0029] A ruler and a backrest ruler are set horizontally along the width of the workbench, with one end of the ruler being fixedly connected to the horizontal edge of the L-shaped fixing plate.

[0033] The extension plate is fixedly connected to the far ends of the two arc-shaped adjustment plates on both sides of its end near the worktable.
[0034] A V-shaped groove is fixedly installed at one end of the worktable (1) near the extension plate;
[0035] A V-shaped protrusion is fixedly installed at one end of the extension plate near the worktable and mates with a V-shaped groove.
[0036] Two detachable support rods are provided, respectively located on both sides of the extension plate away from the worktable; both ends of each detachable support rod are detachably connected to the extension plate and the worktable by adjusting nuts.
[0037] Compared with the prior art, the beneficial effects of the present invention are:
[0038] This invention combines a positioning component that can slide along the width of the worktable with an angle adjustment mechanism integrated thereon that can rotate around a vertical axis and lock, thereby achieving rapid, continuous and precise setting of angle cutting. This overcomes the problems of traditional devices having cumbersome angle adjustment, relying on manual clamps and having difficulty in guaranteeing accuracy.
[0039] The ruler backing part of the present invention can move along the length of the workbench and can be disassembled.

[0041] This invention integrates angle positioning, straight-line support, and table expansion functions into one unit. Each module works collaboratively without interfering with the others, enabling flexible switching between multiple processing modes within a limited space. This significantly improves the overall utilization rate, ease of operation, and overall rigidity of the equipment.

[0057] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0058] This invention provides a multifunctional woodworking push saw table, as shown in Figure 1, including a workbench 1, a table saw 2, an adjustable positioning unit, a ruler support 5, and an extension 6. The workbench 1 serves as the base platform and mounting body of the saw table, consisting of a movable frame and a horizontal platform panel mounted on it, providing a stable and level mounting base and working surface for the table saw 2 and all positioning and support components. The table saw 2 is fixedly mounted in the middle of the workbench 1; specifically, the table saw 2 is an existing structure, a motorized circular saw device fixedly mounted at the opening in the middle of the workbench 1, with the saw blade protruding from the table surface, used to perform straight or angled sawing of the wood.
[0059] The adjustable positioning unit has a positioning component 3 located at one end of the worktable 1 along its length and which can slide along its width. The positioning component 3 serves as the basic moving platform for the angle adjustment mechanism 4, providing the workpiece or auxiliary fixture with continuous linear movement and positioning capability in the width direction of the worktable 1. It also has an angle adjustment mechanism 4 located on the positioning component 3, which can be rotated, adjusted and locked around an axis perpendicular to the worktable 1. The angle adjustment mechanism 4 can realize the angle setting and locking around the vertical axis, guiding the workpiece to perform angle sawing.
[0060] The ruler support part 5 is located at the other end of the workbench 1 along its length direction. The ruler support part 5 can be moved and adjusted along the length direction of the workbench 1 and is detachably connected to the workbench 1.
[0061] The straightedge support 5 provides a longitudinal guide reference parallel to the saw blade of the table saw 2. As a parallel support, it is used to support the workpiece when making straight cuts; at the same time, the cutting width can be set by moving it along the length of the worktable 1. In addition, its detachable design increases the flexibility of equipment layout.
[0062] One end of the extension 6 is connected to the side of the worktable 1 via a flip-down mechanism. The extension 6 has an unfolded state and a retracted state. When unfolded, the extension 6 is fixedly connected to the worktable 1 via a detachable support rod 61, making its upper surface coplanar with the worktable 1. The extension 6 serves as a temporary extension of the worktable 1's surface. When machining long workpieces, it unfolds to provide additional support, preventing workpiece sagging or imbalance and ensuring machining safety and accuracy. When not in use, it can be retracted to save space.
[0063] As one embodiment of this invention, referring to Figure 1, the positioning component 3 includes a fixing frame 31, a sliding rod 32, and an extension platform 33.
[0064] The fixing frame 31 is fixedly installed at one end of the worktable 1. The fixing frame 31 is a rigid frame structure and is firmly installed at one end of the worktable 1 by bolts or welding. As the mounting base and load-bearing frame of the positioning component 3, it can fix and connect the positioning component 3 to the worktable 1 to form a stable position reference; at the same time, it provides a parallel mounting support point for the slide rod 32.
[0065] Two slide bars 32 are provided, which are arranged in parallel on the fixed frame 31 and along the width direction of the worktable 1. Specifically, the slide bar 32 is a cylindrical linear guide rail, which is used to constrain the motion freedom of the extended table surface 33, so that it can only move linearly along the width direction of the worktable 1 (i.e., the axial direction of the slide bar 32), while bearing the lateral force and torque generated during the processing, ensuring the straightness and stability of the movement.
[0066] The extended table 33 is slidably connected to the slide rod 32, and the upper surface of the extended table 33 is coplanar with the worktable 1. Specifically, the extended table 33 is a plate-like structure that matches the material and thickness of the worktable 1, and its bottom is equipped with a linear bearing or bushing that matches the slide rod 32. At the same time, the extended table 33 is provided with a locking mechanism (not shown in the figure) that cooperates with the slide rod 32, such as a tightening knob. In use, the extended table 33 serves as the mounting base for the angle adjustment mechanism 4; at the same time, through the sliding connection with the slide rod 32, it realizes continuous adjustment of itself and the angle adjustment mechanism 4 in the longitudinal position; and after being locked in any position, its surface and the worktable 1 together form a continuous and flat enlarged processing plane.
[0067] In its initial state, the extended table 33 is mounted on the slide bar 32 via its bottom bearing and can slide freely or with slight damping along the slide bar 32. When workpiece width positioning or setting the starting point for angle cutting is required, the operator directly pushes the extended table 33 (along with the angle adjustment mechanism 4 on it). Guided by the double slide bars 32, the extended table 33 moves smoothly along the width direction of the worktable 1.
[0068] Upon reaching the target position, the operator operates the locking mechanism (e.g., tightening the knob). The force generated by the locking mechanism is transmitted to the slide bar 32 through the extended table 33, creating significant static friction between the bearing and the slide bar 32 or through a dedicated clamping element, thereby firmly locking the extended table 33 in the current position of the slide bar 32. At this point, the positioning assembly 3 forms a rigid extended worktable. The upper angle adjustment mechanism 4 can be independently set on this platform; the workpiece can also be supported and operated using this platform against the main table.
[0069] As one embodiment of this invention, referring to Figure 2, the angle adjustment mechanism 4 includes a first guide connecting strip 41, a first V-shaped slide rail 42, a first bracket locking strip 43, an angle positioning bracket 44, a first locking knob 45, an angle reference ruler 46, and an adjustable ruler 47. The first guide connecting strip 41 is arranged along the length of the worktable 1 and is fixedly connected to one end of the extended table surface 33. Specifically, the first guide connecting strip 41 is a long, rigid component with a rectangular guide profile in its cross-section, and it is fixed to one end of the extended table surface 33 along the length of the worktable 1. In implementation, the first guide connecting strip 41 serves as the static base guide rail and main load-bearing beam of the angle adjustment mechanism 4, providing a linear motion reference for the first V-shaped slide rail 42 along the length of the worktable 1, and transmitting the load on the angle adjustment mechanism 4 to the extended table surface 33.
[0070] The first V-shaped sliding groove 42 is fitted onto the first guide connecting strip 41. Specifically, the first V-shaped sliding groove 42 is a long strip-shaped component with a V-shaped groove machined inside, and its other side mates with the guide contour of the first guide connecting strip 41. In implementation, the first V-shaped sliding groove 42 serves as the sliding carrier and adjustment execution structure of the angle adjustment mechanism 4. The sliding engagement with the first guide connecting strip 41 enables the adjustment of the angle positioning bracket 44, the adjustable ruler 47, etc., in the longitudinal position. At the same time, its lateral V-shaped groove provides a force-applying surface for the first locking knob 45.
[0071] The first bracket locking bar 43 has an inverted J-shaped structure. The inner side of its vertical arm mates with the first V-shaped sliding groove bar 42, and its hook-shaped top portion engages with the upper end of the first V-shaped sliding groove bar 42. Specifically, the first bracket locking bar 43 is a long strip-shaped component with an inverted "J"-shaped cross-section. Its inner side of its vertical arm mates with the outer side of the first V-shaped sliding groove bar 42; its top bends inward to form a hook-shaped portion that engages with the upper end of the first V-shaped sliding groove bar 42. In implementation...
[0072] The first bracket locking bar 43 serves as a conversion and force transmission component connecting the first V-shaped slide bar 42 and the bearing angle positioning bracket 44. It engages with the upper edge of the first V-shaped slide bar 42 via a hook-shaped portion at its top, providing a safety guarantee to prevent the entire upper mechanism from disengaging. Simultaneously, during locking, it acts as an intermediary, converting the thrust of the locking knob into a clamping force on the first V-shaped slide bar 42.
[0073] The angle positioning bracket 44 has a horizontally mounted bracket 441 and a J-shaped bracket 442 connected to the bottom of the bracket 441. The inner side of the J-shaped bracket 442 engages with the first bracket locking bar 43, and its bottom hook-shaped portion engages with one side of the first guide connecting bar 41. Specifically, the angle positioning bracket 44 consists of a horizontal bracket 441 and a J-shaped bracket 442 vertically fixedly connected to the bottom of the bracket 441. Its inner side engages with the outer side of the first bracket locking bar 43, and its bottom hook-shaped portion bends inward to engage with one side of the first guide connecting bar 41. In implementation, the bracket 441 provides a mounting surface for the angle reference ruler 46 and the adjustable ruler 47; the J-shaped bracket 442 engages with one side of the first guide connecting bar 41 through its bottom hook-shaped portion, providing a safety function to prevent the entire bracket from falling out in the forward and backward directions, and together with the first bracket locking bar 43, forms a stable connecting frame.
[0074] The first locking knob 45 passes through the J-shaped frame 442 and the first bracket locking bar 43 in sequence, and its end abuts against the V-groove of the first V-shaped sliding bar 42. The first locking knob 45 is threadedly connected to the J-shaped frame 442; specifically, the first locking knob 45 is a bolt with a handle or a butterfly wheel. It passes through the corresponding holes on the J-shaped frame 442 and the first bracket locking bar 43 in sequence, and its threaded part mates with the threaded hole on the J-shaped frame 442. Its end is a smooth tapered shape. In implementation, the first locking knob 45 serves as the locking structure of the angle adjustment mechanism 4. When it is tightened, a huge axial tensile force is generated through the threaded pair, which is converted into a normal top pressure on the V-groove of the first V-shaped sliding bar 42, ultimately achieving friction locking.
[0075] An angle reference ruler 46 is horizontally fixed on the tray frame 441; an adjustable straightedge 47 is set along the length of the worktable 1 and is fixedly connected to the angle reference ruler 46. Specifically, the angle reference ruler 46 is an adjustable sector-shaped component with an angle dial, horizontally fixed on the tray frame 441. The adjustable straightedge 47 is a long straightedge, set along the length of the worktable 1, and is linked and fixed to the rotation axis of the angle reference ruler 46.
[0076] In practice, when it is necessary to move along the length of the workbench 1, loosen the first locking knob 45. Since the first bracket locking bar 43, the angle positioning bracket 44 and its components are as a whole, they can slide easily along the first V-shaped slide bar 42 to adjust the starting position of the angle cutting or adapt to different sizes of work.
[0077] When the lateral position is determined, tighten the first locking knob 45. Tightening the first locking knob 45 generates an axial force, which, through the aforementioned locking force transmission path, is converted into a normal top pressure on the V-groove of the first V-shaped slide bar 42 by the end of the first locking knob 45, ultimately achieving friction locking.
[0078] During angle adjustment, the operator can hold the adjusting component of the adjustable ruler 47 or the angle reference ruler 46, causing the angle reference ruler 46 to rotate around its connection point with the angle positioning bracket 44. While rotating, the operator observes the scale of the angle reference ruler 46 and rotates the adjustable ruler 47 to the desired angle. Finally, the adjusting component of the angle reference ruler 46 is locked to lock the angle after adjustment.
[0079] In operation, the angle positioning bracket 44 acts as a rigid platform. At this time, the adjustable guide 47 forms an angle guide edge. During angle sawing, the workpiece is pushed forward while closely adhering to the adjustable guide 47, thus obtaining a precise bevel.
[0080] As one embodiment of this example, referring to FIG3, the ruler backing part 5 includes a second guide connecting strip 51, a second V-shaped sliding groove strip 52, a second bracket locking strip 53, a second locking knob 54, an L-shaped fixing plate 55, and a ruler backing ruler 56. The second guide connecting strip 51 is located at the other end of the workbench 1 along its length and extends along the length direction; the second V-shaped sliding groove strip 52 is sleeved on the second guide connecting strip 51; the second bracket locking strip 53 has an inverted J-shaped structure, with the inner side of its vertical arm engaging with the side of the second V-shaped sliding groove strip 52, and its top hook-shaped part engaging with the upper end of the second V-shaped sliding groove strip 52; the second locking knob 54 passes through the second bracket locking strip 53, and its end abuts against the V-shaped groove of the second V-shaped sliding groove strip 52, and the second locking knob 54 is threadedly connected to the second bracket locking strip 53; the vertical side of the L-shaped fixing plate 55 is fixedly connected to the second bracket locking strip 53, and its horizontal side extends above the workbench 1; the ruler and guide ruler 56 are horizontally set along the width direction of the workbench 1, and one end is fixedly connected to the horizontal side of the L-shaped fixing plate 55.
[0081] In practice, when it is necessary to move along the length of the workbench 1, loosen the second locking knob 54. Since the second bracket locking bar 53, the L-shaped fixing plate 55 and the ruler backing bar 56 are a whole, they can slide easily along the second V-shaped sliding groove bar 52, allowing the operator to push the ruler backing bar 56 to the corresponding position according to the required sawing width.
[0082] When the lateral position is determined, tighten the second locking knob 54. Tightening the second locking knob 54 generates an axial force, which, through the aforementioned locking force transmission path, is converted into a normal top pressure on the V-groove of the second V-shaped slide bar 52 by the end of the second locking knob 54, ultimately achieving friction locking.
[0083] In operation, the straightedge and guide ruler 56 form a parallel guide reference for the worktable 1. When performing straight sawing, one side of the workpiece is close to the straight edge of the straightedge and guide ruler 56, while the other side faces the table saw 2. When pushing the workpiece forward, the guide ruler ensures that the workpiece passes through the saw blade along a straight path, thereby obtaining a saw cut that is parallel to the edge of the workpiece and has the same width.
[0084] As one embodiment of this invention, referring to FIG4, the extension 6 includes a detachable support rod 61, an arc-shaped adjustment plate 62, an adjustment knob 63, and an extension plate 64.
[0085] Two arc-shaped adjustment plates 62 are provided, respectively rotatably mounted on both sides of the end of the worktable 1; the arc-shaped adjustment plates 62 serve as the main support arms for achieving flipping and coarse angle adjustment. Their arc-shaped grooves allow for a certain adjustment range. In practice, the arc-shaped adjustment plates 62 provide the flipping motion pair, bear the main vertical load, and perform preliminary setting and locking of the unfolding angle.
[0086] Two adjustment knobs 63 are provided, which pass through the arc grooves on the corresponding arc adjustment plates 62 and are threaded to the worktable 1, and are used to adjust and lock the flip angle of the arc adjustment plates 62.
[0087] Adjust the knob 63 to lock the angle of the arc-shaped adjustment plate 62, thereby fixing the basic posture of the extension plate 64 before or after engaging with the V-shaped groove 65.
[0088] The extension plate 64 is fixedly connected to the far ends of two arc-shaped adjustment plates 62 on both sides of its end near the worktable 1; the extension plate 64 provides an extended support plane and serves as a mounting carrier for the V-shaped protrusion 66 and the detachable support rod 61.
[0089] A V-shaped groove 65 is fixedly disposed at one end of the worktable 1 near the extension plate 64. Specifically, the V-shaped groove 65 is a long strip groove with a precisely machined V-shaped cross-section, fixedly installed on the side structure of the worktable 1 near the extension plate 64. Its length matches the width of the extension plate 64. The V-shaped groove 65 cooperates with the V-shaped protrusion 66 to achieve automatic centering and positioning of the extension plate 64 with the worktable 1 in the unfolded state, and to increase shear stiffness.
[0090] A V-shaped protrusion 66 is fixedly disposed at one end of the extension plate 64 near the worktable 1 and mates with a V-shaped groove 65. Specifically, the V-shaped protrusion 66 is a protruding V-shaped strip that matches the cross-section of the V-shaped groove 65 and is fixedly installed on the edge of the extension plate 64 near the worktable 1. When the extension plate 64 is flipped upward to near horizontal, it can be precisely embedded in the V-shaped groove 65 on the worktable 1, thereby completing the mechanical interlock.
[0091] Two detachable support rods 61 are provided, respectively located on both sides of the extension plate 64 at the end away from the worktable 1; both ends of each detachable support rod 61 are detachably connected to the extension plate 64 and the worktable 1 by adjusting nuts 67. The detachable support rods 61 provide auxiliary triangular support at the distal end, further enhancing the rigidity and stability of the extension 6.
[0092] In practice, the extension plate 64 is flipped upwards from its stored state. When the extension plate 64 is nearly horizontal, its V-shaped protrusion 66 begins to contact the V-shaped groove 65 on the worktable 1. Guided by the inclined surface of the V-shaped groove 65, the extension plate 64 automatically completes its positioning, and the V-shaped protrusion 66 embeds into the V-shaped groove 65. At this time, the extension plate 64 and the worktable 1 achieve mechanical interlocking and preliminary alignment at the interface. Then, the adjustment knob 63 is tightened, and finally, the detachable support rod 61 is connected to fix and unfold the extension plate 64. In the working state, the extension plate 64 is tightly connected to the main surface of the worktable 1, which can meet the processing support of long workpieces. When storing, the detachable support rod 61 is loosened and disassembled, the adjustment knob 63 is loosened, and the extension plate 64 is flipped downwards. The V-shaped protrusion 66 disengages from the V-shaped groove 65 until the extension plate 64 is upright and fixed in the stored position.
[0093] In specific implementation of this invention:
[0094] 1) Basic equipment status and functional zoning:
[0095] The workbench 1 provides a stable, level reference plane. The table saw 2 is fixed to the center of the workbench, with the saw blade exposed, serving as the sawing mechanism. The workbench 1 has different guiding and positioning systems at both ends along its length: one end has an adjustable positioning unit (for angle sawing and lateral positioning), and the other end has a ruler rest 5 (for straight sawing and width setting). The extension 6 is hinged to the side of the workbench 1 and is normally retracted to save space.
[0096] 2) Working principle of linear sawing:
[0097] When straight-line sawing parallel to the workpiece edge is required:
[0098] Setting the cutting width: Loosen the second locking knob 54 of the ruler's abutment 5, allowing the ruler's abutment 5 to slide along the second guide connecting strip 51. Push the ruler's abutment 56 to the position required by the table saw blade (i.e., the cutting width), and then tighten the second locking knob 54. The locking force is transmitted through the second bracket locking strip 53, causing the end of the second locking knob 54 to press against the V-groove of the second V-shaped sliding strip 52, achieving friction locking.
[0099] Perform sawing: Place one flat side of the workpiece against the straight edge of the ruler / mountain ruler 56, and align the other side with the saw blade. Push the workpiece forward along the ruler / mountain ruler 56, and the saw blade will cut a straight line that is parallel to the ruler / mountain ruler 56 and has a precisely consistent width.
[0100] 3) Working principle of angle sawing:
[0101] When beveling or angled sawing is required:
[0102] Lateral positioning and installation foundation preparation: Push the extension platform 33 of the positioning component 3 so that it slides along the slide bar 32 in the width direction of the worktable 1, thereby adjusting the overall starting position of the angle adjustment mechanism 4. After adjusting to the appropriate position, lock the locking mechanism on the extension platform 1 that cooperates with the slide bar 32, so that it forms a stable extended platform with the worktable 1.
[0103] Setting the sawing angle: Operate the angle reference ruler 46 on the angle adjustment mechanism 4 to drive the adjustable ruler 47 linked to it to rotate around the vertical axis. Observe the scale on the angle reference ruler 46, rotate the adjustable ruler 47 to the desired angle (e.g., 45°), and then lock the locking part of the angle reference ruler 47.
[0104] Lateral Adjustment: If it is necessary to adjust the starting point of the angle cut, loosen the first locking knob 45. Since the first bracket locking bar 43, the angle positioning bracket 44 and its components are a whole, they can slide easily along the first V-shaped slide bar 42. When the lateral position is determined, tighten the first locking knob 45. Tightening the first locking knob 45 generates an axial force, which, through the above-mentioned locking force transmission path, is converted into a normal top pressure of the end of the first locking knob 45 on the V-shaped groove of the first V-shaped slide bar 42, ultimately achieving friction locking.
[0105] To perform sawing: Place one side of the workpiece against the adjustable guide with the pre-set angle, push the workpiece forward, and the saw blade will cut a precise angled bevel.
[0106] 4) Working principle of supporting long workpieces:
[0107] When the length of the workpiece exceeds the main worktable surface:
[0108] Expanding the extension section: Flip the extension plate 64 upwards from its stored state, and the arc-shaped adjustment plate 62 rotates together. When the extension plate 64 is nearly horizontal, the V-shaped protrusion 66 at its end automatically engages with the V-shaped groove 65 on the worktable 1 under the guidance of the inclined surface, achieving initial centering and positioning. Then tighten the adjustment knob 63 to fix the flipping angle.
[0109] Install reinforcing struts: Connect one end of the two detachable struts 61 to the far side of the extension plate 64, and the other end to the corresponding position on the side of the workbench 1, and tighten them with adjusting nuts 67 to form a stable triangular support.
[0110] Obtain an extended working plane: The upper surface of the extended plate 64, after being unfolded and fixed, remains coplanar with the table surface 1, providing continuous and sufficient support for long workpieces, preventing them from sagging or wobbling during processing, and ensuring straight sawing and safe operation.
[0111] Storage: After completion, remove the detachable support rod 61, loosen the adjustment knob 63, and flip the extension plate 64 downward to the vertical storage position.
[0112] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
