[0046] A saw bench is usually used to place wood during woodworking to facilitate operation. However, the wood is subjected to greater force when being cut and is prone to tilting and shaking. Therefore, a slot is generally provided at one end of the existing saw bench to hold the wood. However, wood has various specifications. Each time a new specification of wood is changed, a saw bench of the corresponding specification generally needs to be replaced, which is inconvenient to use.

[0047] Based on this, it is necessary to provide a workbench 100 and a saw horse 200 for processing external parts, wherein the external parts include wood and other material parts.

[0048] See also Figures 1 to 10 The present application provides a workbench 100, which includes an operating part 1, wherein the operating part 1 has an operating table 11, and the operating table 11 is provided with a plurality of fixing positions 12, each of which can fix an external component of one specification, and a plurality of fixing positions 12 can fix an external component of at least one specification.

[0049] Such an arrangement can fully utilize the operating table 11 of the workbench 100, so that the same workbench 100 can provide multiple fixed positions 12, and thus can adapt to the processing operations of external components of various specifications. The processing of external components of the same or different specifications only requires placing them in the corresponding fixed positions 12, without the need to frequently replace the entire workbench 100.

[0050] Please see again Figure 1 , Figure 2 and Figure 6 In one embodiment, the workbench 100 further includes a supporting portion 2, which is connected to a side of the operating portion 1 that is relatively away from the workbench 100, and is used to support the operating portion 1; wherein the supporting portion 2 is a rigid material piece, and the operating portion 1 is a plastic material piece.

[0051] With such arrangement, the operating part 1 of the plastic material piece can be easily processed into different fixing positions 12, which can reduce processing costs and processing difficulty; the supporting part 2 of the rigid material piece can provide a stable and firm support force for the operating part 1, ensuring that the workbench 100 is easy to process while having sufficient bearing capacity, making the processing of external parts reliable and safe.

[0052] It should be noted that rigid material parts refer to materials with high compressive strength, and plastic material parts refer to materials with good plasticity and easy processing and reshaping. By way of example, rigid material parts include but are not limited to stainless steel parts, iron parts, etc. Plastic material parts include but are not limited to plastic parts, plastic parts, etc.

[0053] Please see again Figures 1 to 3 In one embodiment, at least three fixing positions 12 are provided, and one of the fixing positions 12 is located in the central area of ​​the operating table 11 .

[0054] In this way, at least three fixing positions 12 can make fuller use of the area of ​​the operating table 11, ensuring that the workbench 100 can adapt to various specifications of external components. One of the fixing positions 12 is located in the central area of ​​the operating table 11, which can make relatively more reasonable and uniform use of the area of ​​the operating table 11, and is convenient for users to use.

[0055] Please see again Figures 1 to 3 In one embodiment, the fixing position 12 is a fixing groove opened on the surface of the workbench 100, and the fixing groove runs through both sides of the operating table 11 and the operating part 1 in the width direction. The fixing groove is easy to process and can quickly adapt to external parts of different specifications without other auxiliary accessories. It has a good limiting effect on the external parts, is convenient for taking and placing wood, and is convenient for moving external parts, thereby changing the processing position of the external parts.

[0056] It should be noted that, in this embodiment, the specifications of the plurality of fixing grooves are different, and external components of different specifications can be fixed respectively. It should be further noted that, in this embodiment, the external components fixed by each fixing groove are all made of wood.

[0057] Please see again Figures 1 to 3 In some embodiments, the workbench 100 further includes a clamp 3, the operating portion 1 is provided with a receiving groove 13, and the rod 31 of the clamp 3 is detachably fixed in the receiving groove 13. The clamp 3 can cooperate with the operating table 11 to clamp the external component, and can also cooperate with another clamp 3 or other types of clamping accessories to clamp the external component.

[0058] Please see again Figure 1 , Figure 2 , Figure 3 and Figure 6 In one embodiment, the operating portion 1 is provided with a receiving groove 13 extending along the length direction of the operating portion 1 , and the rod body 31 of the clamp 3 is detachably fixed in the receiving groove 13 .

[0059] With such arrangement, when the fixing groove cannot fit the external component to be processed, the clamp 3 can be used to assist in clamping, thereby expanding the function of the workbench 100 and making the workbench 100 applicable to a wider range of usage requirements.

[0060] It should be noted that, as long as it is ensured that the rod body 31 of the clamp 3 can extend into the accommodating groove 13 and can move in the accommodating groove 13, the accommodating groove 13 can be a closed channel with only side grooves, and the accommodating groove 13 can also be a groove with side grooves and top grooves. It can be understood that the groove of the side groove faces one end of the length direction of the operating part 1 and passes through the end wall of the length direction of the operating part 1, and the groove of the top groove faces the top surface of the operating part 1 and passes through the operating table 11.

[0061] Please see again Figure 1 and Figure 6 Furthermore, accommodating grooves 13 can be provided on both sides of the length direction of the operating portion 1, and each accommodating groove 13 can be correspondingly installed with a clamp 3.

[0062] Please see again Figure 2 , Figures 6 to 10 In one embodiment, the workbench 100 further includes a positioning member 5 , which can extend into the receiving groove 13 and prevent the rod body 31 from moving in the receiving groove 13 .

[0063] With such arrangement, after the rod body 31 moves to a suitable position in the receiving groove 13 , the rod body 31 can be fixed by the positioning member 5 , so as to avoid the rod body 31 sliding during operation, thereby causing the risk of shaking or deviation of the clamped external component.

[0064] Please see again Figures 8 to 10 In one embodiment, the rod body 31 is provided with at least one positioning hole 311, the workbench 100 is provided with a mounting hole 101, the mounting hole 101 is connected to the accommodating groove 13, and the positioning member 5 includes a positioning pin 51, the positioning pin 51 can move in the mounting hole 101, and the positioning pin 51 can extend into the positioning hole 311 of the rod body 31.

[0065] With such arrangement, the locating pin 51 inserted into different locating holes 311 can correspondingly fix the rod body 31 at different positions of the receiving groove 13, thereby adjusting the installation position of the clamp 3, so that the clamp 3 can assist in clamping different external components, thereby increasing the use range of the clamp 3.

[0066] Please see again Fig. 9 and Fig.10 In one embodiment, the extending direction of the mounting hole 101 is perpendicular to the extending direction of the receiving groove 13 .

[0067] Such a configuration facilitates operation and makes it easier to move the positioning pin 51 into the positioning hole 311 of the rod body 31. At the same time, the extension direction of the mounting hole 101 and the extension direction of the accommodating groove 13 enable the positioning pin 51 to have a better limiting effect on the rod body 31 after being inserted into the positioning hole 311, making it difficult for the positioning pin 51 to fall out of the positioning hole 311.

[0068] Please see again Figure 7 In one embodiment, the positioning member 5 also includes a push rod 52, which is movably mounted on the mounting hole 101, and the positioning pin 51 is mounted on the push rod 52. The mounting hole 101 passes through both sides of the operating portion 1 in the width direction. Pressing one end of the push rod 52 from one side of the mounting hole 101 can drive the positioning pin 51 to be inserted into the positioning hole 311, and pressing the other end of the push rod 52 from the other side of the mounting hole 101 can drive the positioning pin 51 to be out of the positioning hole 311.

[0069] With such arrangement, pressing the push rod 52 on different sides can drive the positioning pin 51 to be inserted into or removed from the positioning hole 311 , making the limiting effect of the positioning member 5 on the rod body 31 easier to control and switch.

[0070] Please see again Figure 7 In one embodiment, the push control rod 52 includes a push rod 521 and push buttons 522 disposed at both ends of the push rod 521 , and the positioning pin 51 is disposed on a side of one of the push buttons 522 facing the other push button 522 .

[0071] With this arrangement, the button is easier to press and apply force, and at the same time, a mounting position can be provided for the positioning pin 51 so that there is a gap between the positioning pin 51 and the push rod 521 . The gap can avoid the rod body 31 , so that the movement of the push rod 521 is not easily hindered by the rod body 31 .

[0072] Please see again Figure 7 In one embodiment, when one of the push buttons 522 moves toward the receiving groove 13 , the other push button 522 can slide out of the mounting hole 101 .

[0073] With such a configuration, the user can quickly access the push button without inserting his hand into the installation hole 101 , so as to quickly apply force to the push button 522 to complete the process of inserting or removing the positioning pin 51 from the positioning hole 311 .

[0074] Please see again Figure 1 , Figure 2 and Fig.11 In one embodiment, the clamp 3 also includes a movable clamp body 32, which can be movably mounted on the rod body 31, and the movable clamp body 32 is provided with a first clamping surface 321; the workbench 100 also includes a matching clamp body 4, which can be detachably installed on the operating part 1, and the matching clamp body 4 is provided with a second clamping surface 411, and the first clamping surface 321 can cooperate with one or more second clamping surfaces 411 to clamp the external component.

[0075] With such arrangement, the movable clamping body 32 can move on the rod body 31 , thereby adjusting the distance between the first clamping surface 321 and the second clamping surface 411 of the matching clamping body 4 , thereby adapting to clamp different external components.

[0076] It can be understood that in this embodiment, when the extension direction of the receiving groove 13 is the same as the length direction of the operating portion 1, the adjustment distance between the movable clamp body 32 and the matching clamp body 4 is larger, and more types and specifications of external parts can be clamped.

[0077] It is further understandable that in other embodiments, the operating portion 1 may also be provided with a receiving groove 13 extending along the height direction of the operating portion 1 , and the first clamping surface 321 of the movable clamping body 32 may cooperate with the operating table 11 to clamp the external component.

[0078] Furthermore, in other embodiments, the operating portion 1 may also be provided with a receiving groove 13 extending along the width direction of the operating portion 1 , and the matching clamping body 4 and the movable clamping body 32 may clamp the external component along the width direction of the operating portion 1 .

[0079] It is understood that in other embodiments, the first clamping surface 321 of the movable clamping body 32 can also cooperate with the first clamping surface 321 of another movable clamping body 32 to clamp the external component. For example, a receiving groove 13 is provided at each end of the length direction of the control part, and a clamp 3 is installed on each end.

[0080] Furthermore, in this embodiment, the receiving groove 13 is at a certain distance from the operating table 11. The rod 31 partially protrudes from the end wall of the operating part 1, and the movable clamp 32 is movably mounted on the rod 31 and can move on the part of the rod 31 protruding from the receiving groove 13.

[0081] Please see again Figure 2 In one embodiment, the mating clamp body 4 includes a clamping block 41 and a plug-in block 42 protruding from the bottom of the clamping block 41, the surrounding wall of the clamping block 41 is provided with at least one second clamping surface 411, the operating table 11 is provided with at least one plug-in hole 14, and the plug-in block 42 can be partially or completely inserted into any plug-in hole 14.

[0082] With such arrangement, the mating clip body 4 can be connected to the operating portion 1 through the plug-in block 42 , and at the same time, a second clamping surface 411 of sufficient area can be provided through the clamping block 41 .

[0083] It is understood that the height of the second clamping surface 411 can be adjusted by adjusting the insertion depth of the plug block 42 according to the needs, thereby adjusting the clamping of external components of different heights or thicknesses. It is further understood that the height of the second clamping surface 411 can also be adjusted by adjusting the length of the plug block 42 and / or the hole depth of the plug hole 14.

[0084] Please see again Figure 2 , Figure 3 and Figure 6In one embodiment, a plurality of plug holes 14 are provided, and the plurality of plug holes 14 are divided into two groups, and the two groups of plug holes 14 are respectively located on both sides of the central axis of the operating table 11 in the length direction.

[0085] With such a configuration, the clamp body 4 can be installed in more positions, and the distance between the first clamping surface 321 and the second clamping surface 411 can be adjusted more easily, thereby being adapted to clamp external components of more specifications.

[0086] Please see again Figure 2 , Figure 3 and Figure 6 In one embodiment, the two groups of plug holes 14 are aligned in pairs with the axis of the accommodating groove 13 as the center line, and the connecting line between the two aligned plug holes 14 is orthogonal to the axis of the accommodating groove 13.

[0087] Such a configuration makes it easy to adjust the installation position of the mating clamp 4 on the operating part 1 while keeping the distance between the second clamping surface 411 and the first clamping surface 321 unchanged; it also makes it easy for the second clamping surfaces 411 of the plurality of mating clamps 4 to be quickly aligned along the length direction of the operating table 11 or flush along the width direction of the operating table 11 when a plurality of mating clamps 4 are mated with a movable clamp 32 at the same time.

[0088] Please see again Figure 2 , Figure 3 and Figure 6 In one embodiment, each group of plug holes 14 is evenly distributed along the axial direction of the receiving groove 13. With such an arrangement, it is easier to accurately control the moving distance of the matching clip body 4.

[0089] It can be understood that, as long as the cooperation between the matching clip body 4 and the movable clip body 32 is not affected, in other embodiments, the number and arrangement positions of the plug holes 14 are not limited.

[0090] Please see again Figures 1 to 13 The present application also provides a saw horse 200, comprising a support structure 6 and the above-mentioned workbench 100, wherein the support structure 6 is supported at the bottom of the workbench 100. With such a configuration, the saw horse 200 can be adapted to the processing of various external parts through the multiple fixing positions 12 provided by the workbench 100, effectively improving the application range and convenience of the saw horse 200. The support structure 6 can place the workbench 100 at a suitable working height, improve the comfort of the saw horse 200, and ensure the stability of the workbench 100.

[0091] Please see again Figure 6 and Fig.12 In one embodiment, a receiving cavity 21 with an opening toward the supporting structure 6 is formed at the bottom of the workbench 100 , and the supporting structure 6 can rotate relative to the workbench 100 into the receiving cavity 21 .

[0092] In this way, when the saw horse 200 is not in use, the support structure 6 can be rotated relative to the workbench 100 and stored in the receiving cavity 21, so that the saw horse 200 can be stored or transported easily.

[0093] Please see again Figures 1 to 13 In one embodiment, the workbench 100 also includes a supporting portion 2, which is connected to the side of the operating portion 1 that is relatively away from the workbench 100 and is used to support the operating portion 1; wherein the supporting portion 2 is a rigid material piece, the operating portion 1 is a plastic material piece, and the accommodating cavity 21 is opened in the supporting portion 2.

[0094] In this way, the plastic operating part 1 is easy to process and form into the fixed position 12, and the rigid supporting part 2 can provide reliable and firm connection conditions for the supporting structure 6 while supporting the operating part 1, so that the supporting structure 6 is not prone to tilting and shaking; at the same time, the supporting part 2 can also provide a safe accommodation space for the supporting structure 6 to avoid damage to the supporting structure 6 when transporting and moving the saw horse 200.

[0095] Please see again Figure 1 , Figure 2 and Figures 11 to 13 In one embodiment, the number of the supporting structures 6 is four, and every two supporting structures 6 cooperate to form a set of A-shaped supporting legs 666, and the supporting legs 666 of the two sets of A-shaped supporting legs 666 are respectively arranged at both ends of the bottom of the workbench 100. Such an arrangement can ensure the stability of the workbench 100.

[0096] It should be noted that the two support structures 6 are rotatably connected via a connecting rod 601. The two support structures 6 form two oblique sides of an A-shape, and the connecting rod 601 can form a connecting horizontal line in the middle of the A-shape.

[0097] Please see again Figures 1 to 13 Specifically, the two support legs 666 are rotatably connected to the two sides of the length direction of the supporting part 2 through the connecting shaft 7, and the two support structures 6 of each support leg 666 can be relatively rotated and folded together. After being folded together, the two support legs 666 can be rotated toward the receiving cavity 21 respectively, and stacked and folded into the receiving cavity 21 in sequence. It can be understood that the rotation directions of the two support legs 666 toward the receiving cavity 21 are opposite.

[0098] Please see again Figures 1 to 5 In one embodiment, the support structure 6 includes a support component 61, a lifting component 62 and a locking component 63. The lifting component 62 is connected to the workbench 100 and can be lifted and lowered relative to the support component 61 along the length direction of the support component 61 to drive the workbench 100 to rise and fall. The locking component 63 is arranged on the support component 61 and / or the lifting component 62, and can lock / unlock the lifting and lowering of the lifting component 62 relative to the support component 61.

[0099] With such arrangement, the saw horse 200 can be placed on a desktop, the ground, or the like through the support structure 6. When the height of the bracket needs to be adjusted, the locking assembly 63 is controlled to be unlocked. At this time, the lifting assembly 62 can be lifted and lowered relative to the support assembly 61 along the length direction of the support assembly 61, and can drive the bracket to be lifted and lowered synchronously relative to the support assembly 61, thereby adjusting the height of the bracket so that the bracket can adapt to different working heights. After the adjustment is completed, the locking assembly 63 is controlled to lock the lifting and lowering of the lifting assembly 62 relative to the support assembly 61, thereby ensuring the stability of the bracket supported by the support device and preventing the bracket from shaking or tilting during the processing of wood.

[0100] It can be understood that in other embodiments, the number of support structures 6 can also be set to one, two, three or more than five, as long as it can stably support the workbench 100 and can adjust the height of the workbench 100 as needed. The embodiment of the present invention does not make specific limitations here.

[0101] Please see again Figures 1 to 5 In one embodiment, the locking assembly 63 includes a locking member 631 disposed on one of the support assembly 61 and the lifting assembly 62, and the other of the support assembly 61 and the lifting assembly 62 is provided with a plurality of locking positions 632 arranged at intervals along the sliding direction of the lifting assembly 62; the locking member 631 can cooperate with any locking position 632 to lock the sliding of the lifting assembly 62 relative to the support assembly 61 at different positions. With such a configuration, when the lifting assembly 62 is controlled to slide to a desired height relative to the support assembly 61, it is only necessary to control the locking member 631 to cooperate with the corresponding locking position 632 to limit the lifting and lowering of the lifting assembly 62 relative to the support assembly 61, and the operation is simple and convenient.

[0102] In one embodiment, the locking member 631 is pivotally connected to the support assembly 61 and can be rotated to be inserted into / out of the locking position 632 to lock / unlock the lifting and lowering of the lifting assembly 62 relative to the support assembly 61. With such a configuration, the plug-in adjustment method is simple and convenient, and the locking member 631 is always connected to the support assembly 61 and is not easy to be lost.

[0103] Please see again Figures 1 to 5In one embodiment, the locking assembly 63 further includes a rotating shaft 633 and a torsion spring 634. The locking member 631 rotates relative to the supporting assembly 61 via the rotating shaft 633. The two torsion arms of the torsion spring 634 are respectively limited to the rotating shaft 633 and the supporting assembly 61. With such a configuration, when the external force applied to the locking member 631 is removed, the rotating shaft 633 rotates in the opposite direction under the torsional elastic force of the torsion spring 634 and drives the locking member 631 to rotate in the opposite direction and insert into the locking position 632. In addition, when the locking member 631 is inserted into the locking position 632, the torsion spring 634 can also apply an elastic force to the rotating shaft 633 to improve the stability of the cooperation between the locking member 631 and the locking position 632, and prevent the locking member 631 from accidentally falling out of the locking position 632.

[0104] In one embodiment, the locking member 631 includes an insertion portion 6311 that can be inserted into the locking position 632, and the locking position 632 is set as a socket; when the lifting assembly 62 rises relative to the supporting assembly 61, the inner wall of the socket can push against the insertion portion 6311, so that the insertion portion 6311 is disengaged from the socket. In this way, when the bracket needs to rise, the lifting assembly 62 is directly pulled upward, and the inner wall of the socket can push against the insertion portion 6311, so that the insertion portion 6311 rotates and disengages from the locking position 632, thereby simplifying the adjustment steps when the lifting assembly 62 rises.

[0105] It can be understood that the socket can be a regular or irregular shaped hole structure such as a circular socket or a rectangular socket. As long as the insertion portion 6311 can be inserted into the socket to limit the lifting and lowering of the lifting component 62 relative to the support component 61, the present invention does not make specific limitations here.

[0106] In one embodiment, the insertion portion 6311 is configured as a protrusion or a hook. In this configuration, both the protrusion and the hook can ensure the stability of the insertion portion 6311 when inserted into the insertion hole, thereby ensuring the stability of the locking assembly 63 in the locked state.

[0107] Please see again Figure 2 A supporting foot 611 is also provided at the bottom of the supporting component 61. The user can step on the supporting foot 611 and pull up the lifting component 62 to avoid the supporting component 61 and the lifting component 62 from rising and falling synchronously, which is convenient for the user to operate.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
