Description

Technical Field

[0001] The present application relates to a cutting system. Background Art

[0002] A cutting system in the related art can be used to cut all processable metals including stainless steel, pipes, solid bodies, etc. It has strong heat resistance, abrasion resistance and earthquake resistance, and has a longer service life compared with similar products. Due to its advantages such as flexible and convenient use, it has been widely used in various occasions for cutting various types of bar materials, pipe materials and profiles in industry, household, etc.

[0003] However, when users use the cutting system for cutting, they often encounter the need to cut a large number of workpieces to be cut. At the same time, there may be some working conditions that do not allow such a large cutting system. This will cause users to need to take another cutting tool for cutting, or even if the cutting tool can be removed from the cutting system, it will still take users a lot of time to remove the cutting tool from the cutting system, and then reinstall the cutting tool onto the auxiliary mechanism after cutting. This is very inconvenient for users. Therefore, a cutting system that is convenient for users to operate is needed.

[0004] This section provides background information related to the present application, and these background information are not necessarily prior art. Summary of the Utility Model

Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0033] In the present application, the term "and / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present application generally represents that the associated objects before and after are in an "and / or" relationship.

[0034] In the present application, the terms "connect", "combine", "couple", "mount" may be direct connection, combination, coupling or mounting, or may be indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without setting an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and may include electrical connection or coupling.

[0035] In this application, those of ordinary skill in the art will understand that relative terms used in connection with quantities or conditions (e.g., "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose ranges defined by the absolute values of two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values not using relative terms should also be disclosed as specific values with tolerances. In addition, "substantially" when expressing relative angular positional relationships (e.g., substantially parallel, substantially perpendicular) may refer to plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0036] In this application, those of ordinary skill in the art will understand that the functions performed by components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by parts can also be performed by one part, one component, or a combination of multiple parts.

[0037] In this application, the directional terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that the directional terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive direction, but can also be understood as the side direction. For example, the lower side can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0038] Figure 1 Shown is a cutting system 100, which at least includes a cutting tool, an auxiliary mechanism 10 for cooperating with the cutting tool, and a power supply mechanism 102 for supplying power to the cutting tool.

[0039] For the convenience of describing the technical solutions in this application, the upper, lower, front, rear, left, and right as shown in Figure 1 are defined herein. That is, in this application without specific description, the upper and lower, front and rear, left and right mentioned hereinafter all refer to the state when the band saw 20 is in the position as shown in Figure 1 The cutting tool can be used to cut the workpiece to be cut 29, etc., where the workpiece to be cut 29 includes but is not limited to plates or pipes. In this application, the cutting tool is specifically a band saw 20. The band saw 20 includes an output member, and the output member is used to cut the workpiece to be cut 29. The specific output member is a saw blade 25.

[0040] It should be noted that the workpiece to be cut refers to the workpiece that the user needs to cut. The cut workpiece refers to the workpiece removed from the workpiece to be cut after cutting. The remaining workpiece refers to the remaining workpiece on the workpiece to be cut after cutting. Of course, the remaining workpiece can also become a new workpiece to be cut.

[0041] The auxiliary mechanism 10 is configured to cooperate with the band saw 20 to assist the band saw 20 in completing the cutting. In some embodiments, the band saw 20 can be installed on the auxiliary mechanism 10 for cutting, or the band saw 20 can be removed from the auxiliary mechanism 10 for independent cutting.

[0042] The power supply mechanism 102 is used to supply power to the band saw 20. The power supply mechanism 102 can be DC power supply or AC power supply. As a feasible implementation manner, the power supply structure can be a battery pack 103. The battery pack 103 can be directly installed on the band saw 20, or the battery pack 103 and the band saw 20 can be electrically connected through a power cord.

[0043] As Figures 1 to 4 shown, the band saw 20 includes a housing assembly 21, a rotating wheel assembly 22, a motor, and a switch assembly 23. The housing assembly 21 constitutes the main outer shape part of the band saw 20. The housing assembly 21 can be formed by connecting one or more housings. The housing assembly 21 forms a receiving cavity and a handle portion 24. The switch assembly 23 is at least partially disposed in the handle portion 24. The switch assembly 23 is used for the user to operate to start or stop the motor. The motor is used to provide a power source. The motor is at least partially disposed in the receiving cavity. The rotating wheel assembly 22 is at least partially disposed in the receiving cavity. The rotating wheel assembly 22 includes a driving wheel and a driven wheel. The saw blade 25 is sleeved on the driving wheel and the driven wheel. The driving wheel and the driven wheel are spaced apart to form a cutting area 26. The user uses the saw blade 25 in the cutting area 26 to cut the workpiece to be cut 29. The motor can drive the driving wheel to rotate, and the driven wheel rotates accordingly. A battery pack mounting portion 27 is formed on the housing assembly 21, and the battery pack 103 is detachably mounted on the battery pack mounting portion 27.

[0044] The auxiliary mechanism 10 includes a connecting component 150, a support arm component 120, a limiting component 130, a second adjusting component 140, a third adjusting component 129, a first adjusting component 160, a clamping device 170, a second indicating component 180, a first indicating component 190, a workbench adapting component 111, and a base 110. There are some cases where there is partial structural sharing among the above components, that is, some parts can appear in multiple components, and there are also cases where some parts perform multiple functions.

[0045] The base 110 constitutes the main supporting part of the auxiliary mechanism 10. When the band saw 20 is installed on the auxiliary mechanism 10, the base 110 is located below the band saw 20.

[0046] The support arm assembly 120 is installed on the base 110. The support arm assembly 120 is configured to connect the band saw 20 and the base 110. The support arm assembly 120 can drive the band saw to move relative to the base 110. For example, the support arm assembly 120 can drive the band saw 20 to rotate or move. In this embodiment, the support arm assembly 120 can drive the band saw 20 to reciprocally rotate relative to the base 110 about the first axis 104 in the first direction 106 and the second direction 107. The support arm assembly 120 includes at least one support arm 121. One end of the support arm 121 is connected to the base 110, and the other end is connected to the band saw 20. The user can change the position state of the band saw 20 by rotating the support arm 121. Among them, the first direction 106 is the direction in which the band saw 20 approaches the base 110, and the second direction 107 is the direction in which the band saw 20 moves away from the base 110.

[0047] The connection assembly 150 is configured to connect the support arm 121 and the band saw 20. Through the connection assembly 150, the user can quickly install or remove the band saw 20 from the auxiliary mechanism 10. That is to say, the band saw 20 can be quickly connected or disassembled from the support arm 121 through the connection assembly 150. The band saw 20 can be separated from the auxiliary mechanism 10 and then directly used to cut the workpiece to be cut 29, or it can be installed on the auxiliary mechanism 10 to cut the workpiece to be cut 29.

[0048] The third adjustment component 129 is provided on the support arm assembly 120. And part of the structure of the third adjustment component 129 follows part of the structure of the support arm assembly 120. Specifically, the third adjustment component 129 includes a support arm 121 and an adjustment member. The support arm 121 includes a first connecting arm 1213 and a second connecting arm 1214. Among them, the first connecting arm 1213 and the second connecting arm 1214 can rotate relative to each other through the adjustment member. The first connecting arm 1213 is connected to the base 110, and the second connecting arm 1214 is connected to the band saw 20. The first connecting arm 1213 and the second connecting arm 1214 are rotationally or fixedly connected through the adjustment member. One end of the support arm assembly 120 is connected to the second adjustment component 140.

[0049] The second adjustment component 140 is used to adjust the cutting angle of the band saw 20. The second adjustment component 140 is provided on the base 110. The second adjustment component 140 includes an adjustment block 141. The adjustment block 141 can rotate relative to the base 110 about the second axis 105. Since the band saw 20 is connected to the adjustment block 141 through the support arm assembly 120, that is, when the adjustment block 141 rotates, it can drive the band saw 20 to rotate together about the second axis 105.

[0050] The limiting component 130 is arranged on the rotation path of the second adjustment component 140. On the one hand, it limits the continuous rotation of the second adjustment component 140, and on the other hand, it can also facilitate the user to adjust to the corresponding angular position more quickly. In this application, the limiting component 130 is set at the 0-degree and 45-degree positions. Of course, it can also be set to other angles.

[0051] The second indicating component 180 can cooperate with the second adjustment component 140. When the second adjustment component 140 rotates through the corresponding angle, the second indicating component 180 can indicate the current cutting angle of the band saw 20 for the user to observe.

[0052] The clamping device 170 is used to clamp the workpiece to be cut, so as to facilitate the user to cut with the band saw 20.

[0053] The first adjustment component 160 can cooperate with the clamping device 170. The first adjustment component 160 can be set by the user, so that the lengths of the cut workpieces after cutting by the band saw 20 are consistent. Of course, the first adjustment component 160 can be set by the user multiple times, that is, the user can adjust the length of the cut workpiece according to the needs.

[0054] The first indicating component 190 is fixedly connected to the base 110. The first indicating component 190 is arranged adjacent to the clamping device 170. The first indicating component 190 can cooperate with the first adjustment component 160 to determine the length of the cut workpiece. The first indicating component 190 is used to indicate the position of the saw blade 25 in the cutting area 26 when the band saw 20 is at 0 degrees, so that it is convenient for the user to better determine the length of the cut workpiece according to the position of the cutting line indicated by the first indicating component 190.

[0055] Please refer to Figure 6 、 Figure 7 、 Figure 11 and Figure 12, the support arm assembly 120 includes a first connecting arm 1213, a second connecting arm 1214, an energy storage element 122, a connecting shaft 123, a rotating shaft 124, a first connecting pin 125, a second connecting pin 126, a first movable member 127, and a second movable member 128. The first connecting arm 1213 and the second connecting arm 1214 are connected to form the above-mentioned support arm 121. A connecting assembly 150 is provided at the upper end of the support arm 121, and the lower end of the support arm 121 is connected to the base 110. Specifically, the lower end of the support arm 121 is connected to the adjustment block 141. The adjustment block 141 has a first mounting portion 142 and a second mounting portion 143 arranged at intervals. Corresponding mounting holes are formed on the first mounting portion 142 and the second mounting portion 143, namely a first mounting hole 1421 and a second mounting hole 1431. The first connecting arm 1213 has a first end portion and a second end portion arranged at intervals. Corresponding third mounting holes and fourth mounting holes are formed on the first end portion and the second end portion. At least part of the first end portion and the second end portion are arranged in the first mounting portion 142 and the second mounting portion 143. The connecting shaft 123 is configured to be able to pass through the first mounting hole 1421, the second mounting hole 1431, the third mounting hole, and the fourth mounting hole, so as to connect the first connecting arm 1213 to the adjustment block 141, and the connecting shaft 123 is rotatably connected to the first mounting portion 142 and the second mounting portion 143, that is, the connecting shaft 123 can be driven to rotate around the first axis 104. During the process of the support arm 121 driving the band saw 20 to rotate, there are a maintainable first state and a second state. When the band saw 20 is mounted on the support arm 121 and the support arm 121 is in the first state, at this time the band saw 20 and the auxiliary mechanism 10 are in a state to be working, that is, the band saw 20 is flipped to a state close to the base 110, and the cutting direction 108 of the saw blade 25 in the cutting area 26 is substantially parallel to the base 110. When the band saw 20 is in the first state, it is convenient for the user to carry. When the support arm 121 is in the second state, the support arm 121 is in an unfolded state relative to the base 110, and the cutting direction 108 of the saw blade 25 in the cutting area 26 is substantially perpendicular to the base 110. The band saw 20 is in the second state, and at this time the user can install or disassemble the band saw 20 in the current state.

[0056] The rotating shaft 124 is sleeved on the outer periphery of the connecting shaft 123, and the rotating shaft 124 is disposed in the middle of the first end portion and the second end portion. The energy storage element 122 is sleeved on the outer periphery of the rotating shaft 124. The first movable member 127 can cooperate with the first mounting portion 142 to limit the support arm 121 from disengaging from the current state. Specifically, the first mounting portion 142 has a first stop portion 1411 and a second stop portion 1412, and the support arm 121 will pass through the first stop portion 1411 and the second stop portion 1412 during the rotation around the first axis 104. A first through hole 1212 capable of corresponding cooperation with the first stop portion 1411 and the second stop portion 1412 is formed on the support arm 121, and the first movable member 127 is configured to pass through the first through hole 1212 and cooperate with the first mounting portion 142. Specifically, when the first movable member 127 cooperates with the first stop portion 1411, at this time, the first stop portion 1411 restricts the support arm 121 from rotating towards the second state along the second direction 107, and the first stop portion 1411 keeps the support arm 121 in the first state. When the first movable member 127 cooperates with the second stop portion 1412, at this time, the second stop portion 1412 restricts the support arm 121 from rotating towards the first state along the first direction 106, and the second stop portion 1412 keeps the support arm 121 in the second state. When the first movable member 127 is separated from the first mounting portion 142, the support arm 121 can freely rotate around the first direction 106 or the second direction 107 with the first axis 104 as the axis.

[0057] Specifically, a first connecting pin 125 is disposed on the support arm 121. The first connecting pin 125 is at least partially disposed in the first through hole 1212, and the first connecting pin 125 can cooperate with the first movable member 127. The first movable member 127 is provided with a first positioning portion and a second positioning portion that cooperate with the first connecting pin 125. When the first connecting pin 125 contacts the first positioning portion, the first movable member 127 is configured to be able to contact the first stop portion 1411 or the second stop portion 1412. When the first connecting pin 125 contacts the second positioning portion, the first movable member 127 does not contact the first mounting portion 142.

[0058] A second through hole is provided in the second mounting portion 143, and the second movable member 128 is configured to be able to pass through the second through hole and cooperate with the energy storage element 122. When the second movable member 128 cooperates with the energy storage element 122, when the band saw 20 moves along the first direction 106 with the support arm 121, the energy storage element 122 can generate a force on the support arm 121 to prevent the band saw 20 from approaching the base 110. As the angle of rotation of the support arm 121 increases, the force generated by the energy storage element 122 also increases. In this way, when the band saw 20 approaches the base 110, the other end of the band saw 20 will not directly hit the base 110 due to the heavy weight of the band saw 20 itself. When the second movable member 128 is separated from the energy storage element 122, there is no force interaction between the energy storage element 122 and the support arm 121. Such a setting makes the support arm 121 rotate more flexibly relative to the base 110 without being restricted.

[0059] A second connecting pin 126 is provided on the second mounting portion 143. The second connecting pin 126 is at least partially disposed in the second through hole, and the second connecting pin 126 can cooperate with the second movable member 128. When the second movable member 128 is provided with a third positioning portion and a fourth positioning portion that cooperate with the second connecting pin 126. When the second connecting pin 126 contacts the third positioning portion, the second movable member 128 contacts the energy storage element 122. At this time, during the rotation of the support arm 121, the energy storage element 122 can apply a force to the support arm 121. When the second connecting pin 126 contacts the fourth positioning portion, the second movable member 128 is separated from the energy storage element 122, and the energy storage element 122 does not provide a force to the support arm 121 and the energy storage element 122 rotates together with the support arm 121.

[0060] Specifically, the energy storage element 122 has two ends. One end of the energy storage element 122 is fixedly connected to the first connecting arm 1213, and the other end of the energy storage element 122 is configured to cooperate with the second movable member 128. That is, when the second connecting pin 126 contacts the third positioning portion, the second movable member 128 abuts against the end of the energy storage element 122, and the second movable member 128 prevents the energy storage element 122 from rotating together with the support arm 121. When the second connecting pin 126 contacts the fourth positioning portion, the second movable member 128 is separated from the energy storage element 122, and the energy storage element 122 always rotates together with the support arm 121 during the rotation of the support arm 121. As an implementation manner, the energy storage element 122 is specifically a torsion spring.

[0061] Both the first movable member 127 and the second movable member 128 are generally strip-shaped. The first movable member 127 includes a first holding portion, a first positioning portion, a second positioning portion, and a first fitting portion, and the above components are sequentially distributed along the extending direction of the first movable member 127. The first holding portion is provided at the end of the first movable member 127 and is used for the user to operate. The first fitting portion is provided at the other end of the first movable member 127 and is used to cooperate with the first stop portion 1411 and the second stop portion 1412. The first positioning portion and the second positioning portion are provided between the first holding portion and the first fitting portion, and the first positioning portion and the second positioning portion are spaced apart along the extending direction of the first movable member 127. Specifically, the first positioning portion and the second positioning portion are formed by protruding outward in the circumferential direction of the first movable member 127. The first connecting pin 125 is at least partially located between the first positioning portion and the second positioning portion. It can also be understood that the distance that the first movable member 127 can move is basically equal to the distance between the first positioning portion and the second positioning portion. From the installation direction, first insert the first movable member 127 into the first through hole 1212, and then insert the first connecting pin 125 into the first through hole 1212 in a direction perpendicular to the insertion direction of the first movable member 127, and the position where the first connecting pin 125 is inserted is between the first positioning portion and the second positioning portion. With such a setting, the first movable member 127 can move in the first through hole 1212, and the first movable member 127 does not break away from the support arm 121.

[0062] The second movable member 128 includes a second holding portion, a third positioning portion, a fourth positioning portion, and a second fitting portion, and the above components are sequentially distributed along the extending direction of the second movable member 128. The second holding portion is used for the user to operate. The second holding portion is provided at the end of the second movable member 128, and the second fitting portion is provided at the other end of the second movable member 128 and is used to cooperate with the third stop portion and the fourth stop portion. The third positioning portion and the fourth positioning portion are provided between the second holding portion and the second fitting portion, and the third positioning portion and the fourth positioning portion are spaced apart along the extending direction of the second movable member 128. Specifically, the third positioning portion and the fourth positioning portion are formed by protruding outward in the circumferential direction of the second movable member 128. The second connecting pin 126 is at least partially located between the third positioning portion and the fourth positioning portion. It can also be understood that the distance that the second movable member 128 can move is basically equal to the distance between the third positioning portion and the fourth positioning portion. From the installation direction, first insert the second movable member 128 into the second through hole, and then insert the second connecting pin 126 into the second through hole in a direction perpendicular to the insertion direction of the second movable member 128, and the position where the second connecting pin 126 is inserted is between the third positioning portion and the fourth positioning portion. With such a setting, the second movable member 128 can move in the second through hole, and the second movable member 128 does not break away from the second mounting portion 143.

[0063] Such as Figure 13As shown, the connecting component 150 is disposed at the end of the support arm 121, or it can be said that the connecting component 150 is disposed on the second connecting arm 1214. The connecting component 150 is used for installing and removing the band saw 20. The connecting component 150 includes a support arm 121 and an operating handle 151. The support arm 121 is connected to the adjusting block 141, and the operating handle 151 can pass through the support arm 121 and be connected to the housing assembly 21 of the band saw 20. When the band saw 20 is installed on the connecting component 150, the support arm 121 abuts against the band saw 20. A third through hole through which a part of the operating handle 151 can pass is formed in the second connecting arm 1214. The end of the second connecting arm 1214 further includes a receiving space 1211 capable of receiving a part of the housing assembly 21, and the receiving space 1211 communicates with the third through hole. A connecting portion 28 is formed on the housing assembly 21 in contact with the second connecting arm 1214. The connecting portion 28 can be at least partially located in the receiving space 1211. The connecting portion 28 has a clamping portion that can cooperate with the operating handle 151. The operating handle 151 passes through the third through hole and abuts against the clamping portion located in the receiving space 1211. At this time, the second connecting arm 1214 and the band saw 20 are connected. When the operating handle 151 is separated from the clamping portion, the second connecting arm 1214 is separated from the band saw 20. The operating handle 151 and the clamping portion are specifically threadedly connected. An external thread is provided at the end of the operating handle 151, and the clamping portion is a groove with an internal thread provided therein. To ensure the stability of the connection between the band saw 20 and the support arm 121, the connecting component 150 further includes a positioning screw. The positioning screw is disposed outside the receiving space 1211 and is configured to be able to abut against the axial direction of the operating handle 151. The positioning screw is threadedly connected to the receiving space 1211. After the operating handle 151 is inserted into the receiving space 1211 and tightened with the connecting portion 28, the positioning screw is tightened so that the positioning screw contacts and abuts against the operating handle 151, thereby ensuring the stability of the connection between the support arm 121 and the band saw 20.

[0064] Connected to the other end of the component of the support arm 121 is the second adjusting component 140. The second adjusting component 140 is connected to the base 110, and the second adjusting component 140 can drive the band saw 20 to rotate relative to the base 110 about the second axis 105. The second adjusting component 140 includes an adjusting block 141, a connecting member, an adapter, and a locking component 144. The connecting member passes through the adjusting block 141 to connect the adjusting block 141 to the base 110, and the adjusting block 141 can be driven to rotate forward and backward about the connecting member as an axis. The locking component 144 can be driven to drive the adjusting block 141 to rotate. A guide rail through which the locking component 144 can move is formed on the base 110, and the extending direction of the guide rail is substantially in the circumferential direction with the second axis 105 as an axis. The adapter passes through the guide rail and is installed on the adjusting block 141, and the adapter can rotate with the adjusting block 141. Specifically, the adapter and the adjusting block 141 can be threadedly connected.

[0065] The locking component 144 is used to lock the adjusting block 141. The locking component 144 includes a handle, an intermediate member, an elastic member, a sleeve, and a resisting member. A hole is formed in the adjusting block 141. After the resisting member passes through the hole in the adjusting block 141, the resisting member can cooperate with the guide rail. That is, when the resisting member contacts and resists against the guide rail, the adjusting block 141 remains fixed relative to the base 110. When the resisting member separates from the guide rail, the user can drive the adjusting block 141 to rotate about the second axis 105 by moving the adjusting wrench. The intermediate member is threadedly connected to the resisting member. The handle can be held and operated by the user. The handle is sleeved outside the intermediate member, and a part of the intermediate member protrudes from the handle. The elastic member is sleeved on the intermediate member. One end of the elastic member resists against the handle, and the other end resists against the sleeve. The intermediate member and the resisting member are threadedly connected. The resisting member partially passes through the guide rail into the intermediate member. The user tightens the intermediate member and the resisting member by rotating the handle, thereby locking the adjusting block 141 to the base 110. The user can find that by rotating the handle to loosen the intermediate member and the resisting member, the user can then hold the handle to drive the adjusting block 141 to rotate.

[0066] The adjusting block 141 is formed with a first mounting portion 142 and a second mounting portion 143 connected to the first connecting arm 1213. Among them, when the adjusting block 141 rotates forward about the second axis 105, it is a positive rotation, and when the adjusting block 141 rotates backward, it is a reverse rotation. The band saw 20 is connected to the adjusting block 141. When the adjusting block 141 rotates, it can drive the band saw 20 to rotate together. In this way, the position of the saw blade 25 on the band saw 20 will also change accordingly. During the process of the saw blade 25 being driven to cut, the saw blade 25 in the cutting area will inevitably form a cutting plane P. In this application, it is defined that when the cutting direction 108 of the saw blade 25 in the cutting area 26 is substantially parallel to the left-right direction, the cutting angle of the band saw 20 is 0 degree at this time. When the saw blade 25 rotates with the adjusting block 141, the cutting angle changes with the rotation of the saw blade 25.

[0067] On the path of rotation of the adjustment block 141, the auxiliary mechanism 10 includes a limit assembly 130 that cooperates with the adjustment block 141. The limit assembly 130 includes a first angle stopper 131 and a second angle stopper 132. Due to the requirements of the working conditions, the cutting angle of the band saw 20 is generally limited. It can also be understood that the rotation angle of the adjustment block 141 is limited. That is, two angle stoppers are provided on the rotation path of the adjustment block 141, which are defined here as the first angle stopper 131 and the second angle stopper 132. When the cutting angle of the band saw 20 is 0 degrees, the adjustment block 141 abuts against the first angle stopper 131. When the cutting angle of the band saw 20 is at the maximum preset position, the adjustment block 141 abuts against the second angle stopper 132. That is to say, the adjustment block 141 can only rotate within the range formed by the first angle stopper 131 and the second angle stopper 132. The first angle stopper 131 and the second angle stopper 132 can be provided anywhere as long as they can limit the further rotation of the adjustment block 141. In this embodiment, both the first angle stopper 131 and the second angle stopper 132 are provided on the base 110. The structures of the first angle stopper 131 and the second angle stopper 132 are basically the same. The first angle stopper 131 includes a limiting portion and a limiting screw. A limiting portion is formed on the base 110. The limiting screw is threadedly connected to the limiting portion. Specifically, the limiting portion is a through hole with internal threads formed therein, and the limiting screw partially passes through the limiting portion. During the rotation of the adjustment block 141, the adjustment block 141 will abut against the limiting screw protruding from the limiting portion, that is, the limiting screw restricts the further rotation of the adjustment block 141. The cutting angle refers to the angle between the cutting plane P of the saw blade 25 and the left-right direction. It can also be understood as the angle between the cross-section of the workpiece to be cut 29 after the band saw 20 cuts the workpiece to be cut 29 and the horizontal plane.

[0068] Continuing to refer Figures 8 to 10 As shown, during the rotation of the adjustment block 141, it has at least an initial position and a preset adjustment position. When the adjustment block 141 is in the initial position, the cutting angle of the band saw 20 is 0 degrees, that is, the surface to be cut after the user finishes cutting is basically parallel to the left-right direction. When the adjustment block 141 is at the preset adjustment position, the cutting angle of the band saw 20 is at any position greater than 0 degrees, that is, the surface to be cut by the user intersects with the left-right direction. The maximum preset adjustment position can be set at different positions, which are set at different positions according to the different maximum cutting angles that the band saw 20 can cut. In this embodiment, the cutting angle of the band saw 20 is set to 45 degrees, that is, when the cutting angle of the band saw 20 is 45 degrees, the position where the adjustment block 141 is located is the maximum preset adjustment position. The user can adjust between the initial position and the maximum preset adjustment position. With this setting, the user can rotate the angle according to the actual situation, so as to cut the workpiece to be cut 29 into the required components.

[0069] The first angle stopper 131 in the position-limiting assembly 130 is arranged at the position where the adjusting block 141 abuts against the first angle stopper 131 when the cutting angle of the band saw 20 is 0 degrees. Similarly, the second angle stopper 132 in the position-limiting assembly 130 is arranged at the position where the adjusting block 141 abuts against the second angle stopper 132 when the cutting angle of the band saw 20 is 45 degrees. When the user cuts with the band saw 20, horizontal cutting and 45-degree cutting are generally the most commonly used cutting methods. By setting the position-limiting assembly 130, the user can directly rotate the adjusting block 141 to the position where it abuts against the position-limiting assembly 130 to obtain the cutting angle required by the user. There is no need for the user to measure the angle with tools such as calipers and then rotate the adjusting block 141, and precise alignment is also required when rotating the adjusting block 141. It is convenient for the user to adjust the angle.

[0070] Since the band saw 20 will rotate to different angles in actual working conditions. To facilitate the user to observe the current rotation angle of the band saw 20, the auxiliary mechanism 10 further includes a second indicating assembly 180. The second indicating assembly 180 is installed on the adjusting block 141 and can rotate together with the adjusting block 141. The second indicating assembly 180 includes an indicating element 181, a fastener, and an angle scale 182. The indicating element 181 cooperates with the angle scale 182 to indicate the current cutting angle of the band saw 20. The fastener is used to install the indicating element 181 on the adjusting block 141. Specifically, an angle scale 182 is arranged around the base 110 in a circumferential distribution with the second axis 105 as the axis. The angle scale 182 is arranged near the guide rail and is fixedly connected to the base 110. The fastener passes through the indicating element 181 and fixedly connects the indicating element 181 to the adjusting block 141. When the fastener installs the indicating element 181 on the adjusting block 141, the indicating element 181 always indicates on the angle scale 182. In this way, when the user drives the adjusting block 141 to rotate, the second indicating assembly 180 is driven to move together. After the indicating element 181 moves, it indicates the corresponding angle scale 182. This is convenient for the user to observe the rotation angle of the band saw 20 and is also convenient for the user to adjust the actual angle during the cutting process.

[0071] The auxiliary mechanism 10 further includes a clamping device 170, and the clamping device 170 is installed on the base 110. The clamping device 170 includes a clamping assembly 171 and a locking assembly 176. The clamping assembly 171 is used to clamp the workpiece to be cut 29, and the movable assembly is used to lock the clamping assembly 171 so that the clamping assembly 171 and the workpiece to be cut 29 remain relatively fixed. The clamping assembly 171 includes a fixing member 172, a fixing portion 173, a movable portion 174, and a sliding surface 175 for the movable portion 174 to move. The fixing member 172 is fixedly connected to the base 110 or integrally formed therewith. The fixing portion 173 is fixedly connected to the fixing member 172, and the movable portion 174 can move relative to the fixing portion 173. Both the fixing portion 173 and the movable portion 174 are installed on the fixing member 172, and the movable portion 174 can be driven by a third movable member 177 to move in a direction approaching or away from the fixing portion 173. The placement surface is used to guide the sliding of the movable member. At the same time, the sliding surface 175 between the fixing portion 173 and the movable portion 174 becomes larger or smaller as the movable portion 174 moves. When the exposed sliding surface 175 between the fixing portion 173 and the movable portion 174 can place the workpiece to be cut 29, the user can place the workpiece to be cut 29 on the sliding surface 175, and then use the cooperation between the fixing portion 173 and the movable portion 174 to lock or release the workpiece to be cut 29. The placement surface is fixedly connected to the fixing member 172 or integrally formed therewith, and the placement surface is substantially a plane.

[0072] The movable assembly includes a clamping member 178, a third movable member 177, and a guiding member 179. The third movable member 177 can be driven by the user to drive the movable portion 174 to move. The third movable member 177 is fixedly connected to or integrally formed with the movable portion 174, that is, when the third movable member 177 is driven by the user to move in the left-right direction, the movable portion 174 moves accordingly. The clamping member 178 is used to limit the movement of the third movable member 177. The guiding member 179 is fixedly connected to the fixing member 172, and the guiding member 179 is movably connected to the clamping member 178. A part of the third movable member 177 is in contact with the guiding member 179, and the third movable member 177 can move relative to the guiding member 179. The guiding member 179 cooperates with the clamping member 178 to limit the movement of the third movable member 177.

[0073] The clamping member 178 is pivotally connected to the guiding member 179. The clamping member 178 includes an operating portion and a clamping portion, and the guiding member 179 includes a guiding portion that cooperates with the clamping portion. The operating portion can be used for operation so that the clamping member 178 rotates relative to the guiding member 179. The clamping portion and the guiding portion are semi-circular, and the part of the third movable member 177 that cooperates with the clamping member 178 and the guiding member 179 is cylindrical, that is, the clamping portion and the guiding portion are arranged on the outer periphery of the third movable member 177. Threads are formed on the clamping portion, and threads are also provided on the third movable member 177 that cooperates with the clamping member 178. When the threads on the clamping portion are separated from the threads on the third movable member 177, the user can drive the third movable member 177 to move. When the threads on the clamping portion abut against the threads on the third movable member 177, the movement of the third movable member 177 is restricted, so that the fixed portion 173 and the movable portion 174 can remain relatively fixed.

[0074] As an implementation manner, corresponding working protective sleeves 200 can be connected to both the fixed portion 173 and the movable portion 174. The working protective sleeves 200 are used to protect the workpiece to be cut 29 and prevent the workpiece to be cut 29 from being damaged when the fixed portion 173 and the movable portion 174 are used to firmly lock the workpiece to be cut 29. The working protective sleeves 200 are detachably and fixedly connected to the fixed portion 173 and the movable portion 174. Specifically, the working protective sleeves 200 can be installed on the fixed portion 173 or / and the movable portion 174 by means such as, but not limited to, screws, pins, rivets, movable buckles, magnetic attraction, etc. In this embodiment, the working protective sleeves 200 can be fixedly connected to the fixed portion 173 and the movable portion 174 by means of magnetic attraction. The working protective sleeves 200 can be made of flexible materials such as rubber.

[0075] The clamping device 170 can be driven by the user to have an active state and a locked state. When the clamping device 170 is in the locked state, the workpiece to be cut 29 remains relatively fixed to the base 110, and the user can use the band saw 20 to cut it. When the clamping device 170 is in the active state, the workpiece to be cut 29 is released, and the user can pick up or move the workpiece to be cut 29.

[0076] The specific operation method is as follows. When the user needs to lock the workpiece to be cut 29, the user drives the operation part to turn the clamping part 178 upwards to separate the clamping part from the third movable part 177. Then, the user moves the third movable part 177 towards the fixing part 173 until both the fixing part 173 and the movable part 174 abut against the workpiece to be cut 29. At this time, the user turns the clamping part 178 downwards, and the thread of the clamping part contacts the thread on the movable part 174. The user continues to turn the third movable part 177 towards the fixing part 173 until the thread on the clamping part abuts against the thread on the third movable part 177, that is, the third movable part 177, the clamping part 178, and the guiding part 179 are locked. The movement of the third movable part 177 is restricted, so that the third movable part 177 is locked in the current position, that is, the clamping device 170 is in the locked state. At this time, the clamping device 170 is in the locked state. When the user needs to release the workpiece to be cut 29, the user turns it in the direction away from the fixing part 173 until the third movable part 177, the clamping part 178, and the guiding part 179 are released. Then, the user turns the clamping part 178 upwards, so that the user can directly move the movable part 174 in the direction away from the fixing part 173, and then the workpiece to be cut 29 can be released. At this time, the clamping device 170 is in the active state.

[0077] In addition, the locking assembly 144, the second indicating assembly 180, and the clamping device 170 are all arranged on one side of the cutting plane P. During normal operation, the user generally stands on one side of the workbench. By arranging the above structures on one side of the cutting plane P, it is convenient for the user to operate during use and also convenient for the user to observe the cutting area 26 and the entire auxiliary workbench during work.

[0078] Please refer to Figure 10 and Figure 13As shown, the auxiliary mechanism 10 further includes a first adjustment assembly 160 that can cooperate with the clamping device 170. The first adjustment assembly 160 is used to limit the length of the workpiece after the workpiece to be cut 29. It can be understood that it is used to cut workpieces of equal length. The first adjustment assembly 160 includes a first locking member, a stop block 162, a second locking member, and a movable rod 161. The stop block 162 is sleeved on the movable rod 161, and the stop block 162 can reciprocate on the movable rod 161 and be held. The first locking member is configured to lock the stop block 162 to the movable rod 161. The movable rod 161 is configured to be able to reciprocate relative to the fixed member 172. When the stop block 162 is fixed to the movable rod 161 by the first locking member, the movable rod 161 can drive the stop block 162 to reciprocate relative to the fixed member 172. That is, the user can adjust the distance between the stop block 162 and the cutting plane P by adjusting the position of the movable rod 161 or the stop block 162. The stop block 162 is configured to cooperate with the workpiece to be cut 29, that is, one end of the workpiece to be cut 29 can abut against the workpiece to be cut 29. The second locking member is used to fix the stop block 162 on the movable rod 161, and the second locking member is used to mount the movable rod 161 to the fixed member 172. After the second locking member locks the movable rod 161, when the stop block 162 does not move, the distance between the stop block 162 and the cutting plane P will become a fixed value. In this way, the workpieces after cutting the workpiece to be cut 29 by the user are all equal. In this way, the user can adjust the distance between the stop block 162 and the cutting plane P according to the actual situation, and then adjust the dimension in the length direction of the workpiece to be cut. That is to say, with the above structure, the user has multiple ways to adjust the distance between the stop block 162 and the cutting plane P. One way is to adjust the relative position between the stop block 162 and the movable rod 161, and then adjust the position between the stop block 162 and the cutting plane P. Another way is to adjust the position of the movable rod 161 relative to the fixed member 172 to adjust the position between the stop block 162 and the cutting plane P, or to adjust the movable rod 161 and the stop block 162 together to determine the position between the stop block 162 and the cutting plane P. The setting of the above structure increases the adjustment range of the user and facilitates the user's adjustment.

[0079] As another implementation, the movable rod 161 is detachably connected to both sides of the fixing member 172, or in other words, the stoppers 162 can be arranged on both sides of the cutting plane P. In the front-rear direction, the fixing member 172 has a connecting hole 112 that penetrates through from front to back. The movable rod 161 can be inserted into the connecting hole 112 and reciprocate within the connecting hole 112. The user can adjust the movable rod 161 to a suitable position according to needs and then fix the movable rod 161 to the fixing member 172 through the second locking member. When the user actually uses it, there will be different working conditions, different operating environments, and different operating habits of the user. By setting the movable rod 161 so that the distance between the stopper 162 and the cutting plane P can be adjusted on both sides of the cutting plane P by the user, the user can select the position of the stopper 162 according to requirements during cutting, thus facilitating the user's operation.

[0080] Furthermore, both the first fastener and the second fastener are screws. A through hole through which the movable rod 161 can pass is formed on the stopper 162, that is, the stopper 162 reciprocates on the movable rod 161 through the through hole. Another through hole into which the first fastener can be inserted is formed in a direction perpendicular to the extending direction of the through hole. The screw is inserted into the through hole and abuts against the movable rod 161 to limit the movement of the stopper 162. Similarly, the movable rod 161 and the fixing member 172 also adopt the above structure, which will not be elaborated here.

[0081] As Figures 1 to 13 shown, the auxiliary mechanism 10 further includes a first indicating component 190 for indicating the specific cutting position 192 of the saw blade 25. The first indicating component 190 is installed on the fixing member 172, or in other words, at least part of the first indicating component 190 is arranged on the moving path of the band saw 20 rotating about the first axis 104. Specifically, the first indicating component 190 includes an indicating plate 191, and the indicating plate 191 is fixedly connected to the fixing member 172. When the band saw 20 rotates downward, the saw blade 25 will contact the indicating plate 191 and cut a cutting groove on the indicating plate 191 or cut off part of the indicating plate 191. In this way, the next time the band saw 20 is used, the specific position where the current saw blade 25 cuts can be known. When the user uses the first adjusting component 160 to cut a workpiece 29 to be cut with a certain length, the user can directly adjust the distance between the stopper 162 and the cutting groove on the indicating plate 191 to calculate the desired size, facilitating the user to cut the required size. To facilitate the user to observe the cutting position 192 and measure the distance, the indicating plate 191 is specifically arranged at the rear side of the sliding surface 175 and adjacent to the sliding surface 175. In addition, the upper plane 193 of the indicating plate 191 is substantially flush with the sliding surface 175 or the upper plane 193 of the indicating plate 191 is slightly lower than the sliding surface 175.

[0082] The structures in the auxiliary mechanism 10 in this application are relatively simple, thus reducing the weight of the auxiliary mechanism 10. In this application, the weight of the auxiliary mechanism 10 is greater than 0 kg and less than or equal to 12.5 kg. When cutting a large number of workpieces to be cut 29, users often install the band saw 20 on the auxiliary mechanism 10 and then perform cutting. However, the workpieces to be cut 29 are often not in only one place, and users need to change the working site to continue cutting. In this case, users often choose to directly carry the entire cutting system 100. Due to the above situation, for users, the lighter the cutting system 100, the more convenient it is for them to carry. Since the choice of the type of band saw 20 is often affected by the workpiece to be cut 29, for the cutting system 100, only when the weight of the auxiliary mechanism 10 is relatively light can it be convenient for users to carry or transport. However, an overly light auxiliary mechanism 10 may also cause the band saw 20 to tip over during use by the user. Therefore, setting the weight of the auxiliary mechanism 10 within the above range can not only reduce the weight of the cutting system 100 and facilitate user handling, but also ensure the cutting stability of the band saw 20 installed on the auxiliary mechanism 10.

[0083] In the actual working conditions, after the band saw 20 is first installed on the base 110, check whether the indicating element 181 is at the 0-degree position, and then rotate the band saw 20 downward for cutting until a part of the indicating plate 191 is cut off. At this time, the edge of the remaining part is the cutting position 192 of the saw blade of the band saw 20 at the 0-degree angle. That is to say, when the user uses the auxiliary mechanism 10 to cut the band saw 20 next time, the user can directly know the cutting position 192 of the band saw 20 by observing the remaining indicating plate 191. During any complete cutting process of the band saw 20, the saw blade 25 in the cutting area 26 contacts at least part of the indicating plate 191. According to the foregoing, the adjusting block 141 drives the band saw 20 to rotate. During the rotation of the band saw 20, the cutting direction 108 of the saw blade 25 in the cutting area 26 also changes accordingly, but the band saw 20 always contacts part of the indicating plate 191. The auxiliary mechanism 10 further includes a workbench adaptation assembly 111, and the workbench adaptation assembly 111 can mount the auxiliary mechanism 10 on the ground, a workbench or a floor stand 113. As a specific implementation manner, the auxiliary mechanism 10 can be installed on the floor stand 113 for installing a table saw or a miter saw, so that users can install different tools for cutting according to the actual use situation at the cutting site, which is convenient for users to use.

[0084] Specifically, the workbench adaptation assembly 111 is formed with several mounting posts on the base 110, and screws can pass through the mounting posts to fixedly mount the base 110 on the floor stand 113. Of course, users can also disassemble the auxiliary mechanism 10 from the floor stand 113 and install a table saw on the floor stand 113 for use.

[0085] During the specific use of the auxiliary mechanism 10 and the band saw 20, when the band saw 20 is in the state as follows Figure 1 the band saw 20 can perform a compound movement of upward rotation and / or forward and backward rotation relative to the base 110. That is, the band saw 20 can rotate upward relative to the base 110, or the band saw 20 can be moved forward relative to the base 110 through the adjusting block 141. Of course, the above two movements can also be combined, that is, the band saw 20 can rotate forward by a certain angle and then rotate upward or downward to cut the workpiece to be cut 29.

[0086] The working changes of the band saw 20 are described here. When the band saw 20 is not installed on the support arm 121, the second positioning portion on the first movable member 127 contacts the first connecting pin 125, and the fourth positioning portion on the second movable member 128 contacts the second connecting pin 126. At this time, the support arm 121 can rotate upward or downward around the first axis 104. At the same time, since the energy storage element 122 does not contact the second movable member 128, that is, the energy storage element 122 does not provide force to the support arm 121. In this way, the support arm 121 only has its own gravity and the force applied by the user. When the user rotates downward with the first axis 104 as the axis, since there is no reaction force applied by the energy storage element 122 to the support arm 121, that is, the support arm 121 can contact the base 110. At this time, the auxiliary mechanism 10 can be called the original state. In the current state, the user can store the auxiliary mechanism 10 in a storage place.

[0087] In this embodiment, the band saw 20 is installed on the support through the connection assembly 150. The specific operation method is that the user loosens the operation handle 151, removes the operation handle 151 from the support arm 121, then inserts the connecting portion 28 on the band saw 20 into the accommodation space 1211 on the second connecting arm 1214 to achieve preliminary alignment. After the third through hole and the clamping portion are preliminarily aligned, the operation handle 151 is partially inserted through the third through hole and into the clamping portion, and then the operation handle 151 is tightened, thereby completing the installation of the band saw 20 to the auxiliary mechanism 10. Similarly, for removing the band saw 20 from the support arm 121, the user only needs to hold the operation handle 151 with one hand and hold the handle portion 24 of the band saw 20 with the other hand. The hand holding the operation handle 151 loosens the operation handle 151 to make the force interaction between the band saw 20 and the support arm 121 disappear. Once the force interaction disappears, the user can hold the handle portion 24 to remove the band saw 20 from the support arm 121.

[0088] When the band saw 20 is installed on the support arm 121, when the second positioning portion on the first movable member 127 contacts the first connecting pin 125 and the fourth positioning portion on the second movable member 128 contacts the second connecting pin 126, at this time the support arm 121 can be driven to drive the band saw 20 to rotate upward or downward around the first axis 104. At the same time, since the energy storage element 122 does not contact the second movable member 128, that is, the energy storage element 122 does not provide a force to the support arm 121. In this way, the gravity of the support arm 121 itself, the force applied by the user, and the gravity of the band saw 20 itself act on the support arm 121. Because the band saw 20 is very heavy, when the user holds the handle portion 24 of the band saw 20 and rotates the band saw 20, due to the lack of other external forces, the band saw 20 is likely to have too large a gravitational potential energy due to its own weight, resulting in the free end of the band saw 20 hitting the base 110 when the band saw 20 rotates. To avoid this situation, when the user rotates the band saw 20, a force needs to be applied to the band saw 20 at all times, so as to ensure that the band saw 20 can cut normally and will not hit the base 110. However, for the user, the user needs to apply a force to the band saw 20 throughout the cutting process, which will make the user very strenuous throughout the cutting process.

[0089] When installed on the support arm 121, when the second positioning portion of the first movable member 127 contacts the first connecting pin 125 and the third positioning portion on the second movable member 128 contacts the second connecting pin 126, the support arm 121 can be driven to freely rotate the band saw 20 upward or downward around the first axis 104. In addition, the second movable member 128 abuts against the energy storage element 122, and the energy storage element 122 will interact with the support arm 121 during the rotation of the band saw 20. When the band saw 20 rotates downward, the energy storage element 122 can give the band saw 20 an upward reaction force to slow down the downward rotation speed of the band saw 20. And as the downward rotation angle of the band saw 20 becomes larger, the elastic force generated by the deformation of the energy storage element 122 becomes stronger. This elastic force enables the user to control the rotation of the band saw 20 without much force during the downward rotation. Even after the user applies an initial downward rotation force to the band saw 20 and then stops applying force, the band saw 20 can still rotate downward by virtue of its own weight. However, during its rotation, the elastic force generated by the deformation of the energy storage element 122 also becomes larger and larger until the forces of the two cancel each other out, and the band saw 20 can hover at a certain position close to the cutting line. The above hovering position may not be fixed. With such a setting, when the user uses the band saw 20 for cutting, it will not be the case that the user has difficulty controlling the band saw 20 due to its large gravitational potential energy. Moreover, because the elastic force of the energy storage element 122 and the gravitational potential energy of the band saw 20 can be basically balanced, when the user switches the band saw 20, only a small force needs to be applied to the band saw 20 to achieve cutting. In addition, when the user rotates the band saw 20 upward, the user does not need to use much force to lift the band saw 20.

[0090] The band saw 20 is installed on the support arm 121. When the band saw 20 rotates axially downward about the first axis 104, there are at least two maintainable states, namely the first state and the second state. When the band saw 20 is in the second state, that is, the cutting direction 108 of the saw blade 25 of the band saw 20 is substantially perpendicular or perpendicular to the base 110. When the band saw 20 is in the first state, that is, the cutting direction 108 of the saw blade 25 of the band saw 20 is substantially parallel or parallel to the base 110. When the band saw 20 is in the second state, the first movable member 127 cooperates with the second stop portion 1412 on the first mounting portion 142. When the band saw 20 is in the first state, the first movable member 127 cooperates with the first stop portion 1411 on the first mounting portion 142. In some working conditions, when the user needs to transport or carry the cutting system 100, the user will rotate the band saw 20 to the first state, and then hold the handle portion 24 or the base 110 of the band saw 20 to carry away the cutting system 100. Assuming that the initial state of the cutting system 100 is the second state, at this time the first movable member 127 cooperates with the second stop portion 1412. When the user wants to switch the band saw 20 from the second state to the first state, the user holds the first holding portion and pulls out the first movable member 127 forward. The first positioning portion on the first movable member 127 that was originally in contact with the first connecting pin 125 separates, and continues to move forward until the second positioning portion on the first movable member 127 comes into contact with the first connecting pin 125. At this time, the first adapter portion separates from the second stop portion 1412. At this time, the user can drive the band saw 20 to rotate downward to the first state. When the support arm 121 rotates downward until the first through hole 1212 is substantially aligned with the first stop portion 1411, and then the user drives the first holding portion to push backward. The second positioning portion on the first movable member 127 separates from the first connecting pin 125, and continues to move backward until the first positioning portion on the first movable member 127 comes into contact with the first movable pin, and the first adapter part cooperates with the first stop portion 1411. At this time, the band saw 20 is in the first state. That is, the band saw 20 completes the switching from the second state to the first state. Similarly, when the user wants to switch the band saw 20 from the first state to the second state, just repeat the above operation. During the process of the band saw 20 switching from the first state to the second state, or from the second state to the first state, the energy storage element 122 and the second movable member 128 may or may not be in contact. In addition, the adjusting block 141 can be rotated to any position between the initial position and the maximum rotation position.

[0091] According to the above, the adjusting block 141 can be driven to adjust between the initial position and the maximum adjustment position. As a specific adjustment method, assuming that the current position of the adjusting block 141 is at the initial position, at this time, one end of the adjusting block 141 abuts against the first angle stopper 131. When the user wants to rotate the band saw 20 from the initial position to the maximum adjustment position, the user needs to first rotate the handle to loosen the intermediate member and the abutting member, so that the adjusting block 141 and the base 110 can rotate relative to each other, and then still use the hand holding the handle to rotate in the desired angle until reaching the maximum adjustment position and stop. When reaching the maximum adjustment position, the user tightens the intermediate member and the abutting member. The intermediate member and the abutting member are tightened, that is, the adjusting block 141 and the base 110 are kept relatively fixed.

[0092] When the user wants to complete cutting with a fixed length or a fixed angle, the user needs to first rotate the adjusting block 141 to the required angle. For the convenience of description, the cutting angle of the band saw 20 is defined as 0 degree here, that is, when the adjusting block 141 is in the initial position, the band saw 20 is horizontally cutting at this time. The adjustment method for a fixed angle has been described above and will not be repeated here. For the adjustment method of a fixed length, first determine the position of the cutting line on the indicator board 191 fixed on the base 110, and estimate the position of the stopper 162 based on this starting point. In addition, the stopper 162 can be installed on either side of the cutting plane P. As a way, the stopper 162 can be sleeved on either end of the movable rod 161. Assuming that the stopper 162 is installed on the rear side of the cutting plane P, the user first inserts the movable rod 161 into the connection hole 112 formed on the fixing member 172. Generally, the user will choose to make the part of the movable rod 161 extending out of the connection hole 112 longer than the required length of the user, and then use the second locking member to fixedly connect the movable rod 161 to the fixing member 172, and then measure the required length, adjust the distance between the stopping surface of the stopper 162 and the cutting line to the required position, and then fix the position of the stopper 162, and thus complete the adjustment setting of the fixed length. At this time, the user can perform cutting under the conditions of a fixed angle and a fixed length, so as to cut the required workpiece to be cut.

[0093] The cutting system 100 has at least a first use state and a second use state. When the cutting system 100 is in the first use state, the band saw 20 is installed on the auxiliary mechanism 10, that is, the user can drive the band saw 20 to rotate, so that the saw blade 25 on the band saw 20 approaches the workpiece 29 fixed by the clamping device 170 and complete the cutting. When the cutting system 100 is in the second use state, the band saw 20 is configured to be removable from the auxiliary mechanism 10, and the band saw 20 is directly used for cutting.

[0094] That is to say, by setting up the auxiliary cutting system 100, the user experience can be greatly improved. For some large quantities of, large-sized, or to-be-cut workpieces 29 with angular or dimensional requirements for the workpiece to be cut, the user can fix the to-be-cut workpiece 29 to the auxiliary mechanism 10, so that the functions of the auxiliary mechanism 10 can be utilized to facilitate the user to quickly adjust to the required dimensions or angles, and then complete the cutting quickly. For some temporary cutting, or cutting that requires frequent movement of the working site, the band saw 20 can be directly selected for cutting.

[0095] When the user uses the auxiliary mechanism 10 to cut the to-be-cut workpiece 29, that is, when the user adopts the first usage state of the cutting system 100, the user will fix the to-be-cut workpiece 29 to the clamping device 170. The state where the fixing part 173 and the movable part 174 in the clamping assembly 171 are in contact, and the clamping member 178 and the guiding member 179 clamp and surround the third movable member 177 is defined as the preliminary state. When the user wants to fix the to-be-cut workpiece 29 to the clamping device 170, first drive the clamping member 178 to rotate upward relative to the guiding member 179. Generally speaking, it is to lift the clamping member 178 upward. At this time, the third movable member 177 can be directly pulled by the user to move. The user holds the third movable member 177, and then moves the movable member away from the fixing part 173 until the distance between the movable part 174 connected to the third movable member 177 and the fixing part 173 can place the to-be-cut workpiece 29. The user places the to-be-cut workpiece 29 in the space between the movable part 174 and the fixing part 173, and then rotates the clamping member 178 in the reverse direction to make the clamping member 178 and the guiding member 179 semi-surround the third movable member 177. Then the user drives the third movable member 177 to push the third movable member 177 in the direction close to the fixing member 172 until the fixing part 173, the to-be-cut workpiece 29, and the movable part 174 are in abutment with each other. Then rotate the third movable member 177 to tighten the third movable member 177 and the clamping member 178, thereby fixing the to-be-cut workpiece 29 on the clamping device 170. Then the user can perform cutting. After the cutting is completed, after the user loosens the third movable member 177 and the clamping member 178, the user rotates the clamping member 178 upward relative to the guiding member 179, and then can hold the third movable member 177 and move it away from the fixing part 173 until the distance between the fixing part 173 and the movable part 174 allows the user to freely move the to-be-cut workpiece 29. If the user wants to continue cutting, the above operations can be repeated. For some environments where the auxiliary mechanism 10 cannot be placed, the user can use the workbench adapter assembly 111 to install the auxiliary mechanism 10 on the floor bracket 113, so that it is also convenient for the user to cut. Also, because the auxiliary mechanism 10 raises the operation interface, the user can stand near the floor bracket 113 and then cut the band saw 20, improving the user experience.
