[0001] The invention relates to a workbench and a tool combination system, in particular to a multifunctional workbench and a tool combination system capable of expanding tool functions, belonging to the technical field of woodworking electric tools. Background Art

[0002] In the technical field of electric tools, a workbench used to support a workpiece is generally used to support and fix the workpiece, so as to facilitate the use of handheld electric tools, such as electric circular saws, reciprocating saws, etc., to perform processing operations on the workpiece. However, it can only be used as an ordinary workbench and can only be used to support and fix the workpiece, and its functions are relatively simple.

[0003] The existing pattern saws are mainly desktop pattern saws, which generally include a frame, a power drive component, and a sawing mechanism. The power drive component must be fixed to the frame and can only be used as one of the components of a desktop machine tool. Therefore, this type of desktop pattern saw has a single function and is generally only used for pattern cutting of thinner plates. When cutting, the plate is placed on the upper surface of the frame and the required shape is cut by moving the plate, which can be a shape with complex lines.

[0004] The existing handheld electric reciprocating saw is generally held directly by the user and placed on the workpiece surface to cut the workpiece. This type of reciprocating saw can be used to cut thicker plates and is generally only used for simple straight line cutting. If you want to cut some plates with more complex shapes, this type of tool is difficult to do.

[0005] Therefore, for carpenters in the fields of furniture, home decoration, etc., they often have to prepare both a desktop pattern saw and a handheld electric reciprocating saw to meet different process and operation requirements. This means that multiple sets of tools must be prepared, which will undoubtedly bring disadvantages such as increased site storage space and increased purchase costs.

A graffiti saw blade mounting groove 1511 is disposed at the lower end of the guide column 1510 , into which one end of the graffiti saw blade 300 can be quickly inserted.

[0030] As one of the embodiments, the mounting head 150 includes a left mounting head shell 1530 and a right mounting head shell 1540, wherein a cylindrical guide hole 1501 and a limiting groove 1502 are formed between the left mounting head shell 1530 and the right mounting head shell 1540, the cylindrical guide hole 1501 is used to guide the guide column 1510, and the limiting groove 1502 is used to limit the travel of the guide column 1510.

[0031] The mounting head 150 is also provided with a dust hood 1550, and the dust hood 1550 is provided with a dust nozzle 1551, which can be connected to the suction nozzle of a vacuum cleaner, so that during the cutting operation, the chips can be sucked away by the vacuum cleaner to maintain a good working environment. In addition, the mounting head 150 is also provided with a spring 1503, which supports the guide column 1510, so that the guide column 1510 has a tendency to move upward.

[0032] Fig.11 and Fig.12 The diagram shows a handheld electric reciprocating saw 200 and a reciprocating saw blade 400 used therein. When the handheld electric reciprocating saw 200 is used as a handheld tool, it can cut plates with thicker cross-sections. It is usually equipped with a reciprocating saw blade 400, and the reciprocating saw blade 400 has a handle mounting portion 401, and the handle mounting portion 401 can be quickly installed on the quick-clamp chuck 202 of the handheld electric reciprocating saw 200.

[0033] like Fig.13 As shown, when it is necessary to cut a second type of workpiece 600 having a thicker thickness, the second type of workpiece 600 can be fixed on the table 120 of the workbench 100, and then the second type of workpiece 600 can be cut by moving the handheld electric reciprocating saw 200. The second type of workpiece 600 can be a plate-type workpiece with a cross-sectional thickness between 0.5 and 100 mm.

[0034] like Figures 14 to 16As shown, in order to realize that the handheld electric reciprocating saw 200 can be transformed into a desktop pattern saw, so as to more conveniently perform pattern cutting operations on a first type of workpiece 500 which is thinner than the second type of workpiece, the present invention provides a bottom plate mounting portion 1220 on the bottom surface of the table 120, which is used to fix the bottom plate 210 of the handheld electric reciprocating saw 200 to the bottom plate mounting portion 1220.

[0035] As one preferred embodiment, the bottom plate mounting portion 1220 includes a bottom plate mounting groove 1221 and a pressure plate 1222. The pressure plate 1222 is used to press the bottom plate 210 of the handheld electric reciprocating saw 200 into the bottom plate mounting groove 1221. The mounting groove 1221 is provided on the bottom surface 1202 and is generally in a concave rectangular shape. The bottom plate 210 of the handheld electric reciprocating saw 200 is also generally in a rectangular shape. The bottom plate 210 can be built into the mounting groove 1221, and the bottom plate is limited by the surroundings of the mounting groove 1221 to keep it fixed in the circumferential direction. The two pressure plates 1222 press the bottom plate 210, and the pressure plates are fastened to the bottom surface 1202 of the table 120 by bolts.

[0036] Figures 17 to 19 The example shows a scenario in which the workbench 100 of the present invention is combined with a handheld electric reciprocating saw 300 to be used as a table-type pattern saw. When used as a pattern saw, the pattern saw blade 300 cannot be directly installed on the quick-clamp chuck 202 of the reciprocating saw 300. For this reason, the present invention is provided with a pattern saw adapter 700. The pattern saw adapter 700 has an adapter handle portion 701 that is the same as the handle mounting portion 401 of the reciprocating saw blade 400 at one end, and an adapter mounting groove 702 at the other end. The structure of the adapter mounting groove 702 has the same shape and structure as the mounting groove 1511 on the guide column 150. One end of the pattern saw blade 300 is connected to the mounting groove 1511 of the guide column 150, and the other end is connected to the adapter mounting groove 702.

[0037] In order to facilitate the control of the machine, a control switch 1130, a socket 1140 and a power cord plug (not shown in the figure) are also provided on the support base 110. The power cord plug is used to connect to an external AC power supply, and the socket 1140 is used to connect a plug of a handheld electric reciprocating saw 200 (not shown in the figure).

[0038] When used as a desktop pattern saw, the general process is to insert the plug of the handheld electric reciprocating saw 200 into the socket 1140, keep the switch of the handheld electric reciprocating saw 200 in the closed state, and insert the power cord plug into the socket of the external AC power supply. At this time, the control switch 1130 can be turned on, and the handheld electric reciprocating saw 200 is used as a power source to drive the pattern saw blade 300 to reciprocate. The user can then place the first type of board 500 on the workbench 100 for pattern cutting operations.
