Specific implementation mode

To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference Attached drawing, the present invention is described in further detail.

Please referring initially to Fig. 1, circular sawing machine 10 of the invention includes a workbench 20, a sliding unit 30 and a sawing Unit 40.

Workbench 20 is set up on desktop or other supporting surfaces, with for work-piece.The rear end of workbench 20 has one The support portion 22 up extended.

Please refer to Fig. 1 and 3, sliding unit 30 has the sliding bar 32 that a fixed seat 31 and two is mutually parallel.Gu The bottom end of reservation 31 is fixed in the support portion 22 of workbench 20, and the top of fixed seat 31 has a storage tank 34, storage tank 34 In fixed seat 31 towards the one side of workbench 20；Two sliding bar 32 can axially be arranged in fixed seat 31 along itself Top and the two opposite sides for being located at storage tank 34.In addition, sliding unit 30 has more a slide cover 35, slide cover 35 is affixed In the top surface of two sliding bar 32 and there is two opposite first pivoting portions 36 and a second pivoting portion 37, second pivoting portion 37 is certainly The direction of one of first pivoting portion 36 towards the storage tank 34 far from fixed seat 31 extends backward.

Sawing unit 40 has the saw blade 42 and a handle 49 that a saw arm 41, one is hubbed at saw arm 41.Saw arm 41 is located at Two first pivoting portion 36 of slide cover 35 is hubbed between two sliding bar 32 and by one first pivot 43 so that saw arm 41 one side can drive saw blade 42 relative to start before and after workbench 20 by two sliding bar 32, on the other hand also can be by Pivot joint relationship between slide cover 35 come drive saw blade 42 between an extreme higher position P1 and an extreme lower position P2 relative to About 20 start of workbench.There is saw arm 41 holding part 44, the holding part 44 to be adjacent to the first pivot 43 and have one first End 441 and a second end 442.In this present embodiment, when saw arm 41 is located at extreme higher position P1 as shown in figures 1 and 3, hold The second end 442 for setting portion 44 is detached from the storage tank 34 of fixed seat 31, when saw arm 41 is located at the extreme lower position as shown in Fig. 2 and 4 When P2, the second end 442 of holding part 44 is located in the storage tank 34 of fixed seat 31, no matter however saw arm 41 is located at extreme higher position The first end 441 of P1 or extreme lower position P2, holding part are respectively positioned on outside the storage tank 34 of fixed seat 31.In addition, sawing unit 40 With more a saw blade cover 45 and a connecting rod 46, saw blade cover 45 is hubbed at saw arm 41 and covers at saw blade 42, and connecting rod 46 has The first end 462 of one first end 462 and a second end 464, connecting rod 46 has a strip hole 466, and connecting rod 46 is by strip hole 466 It is slippingly socketed on a fixing piece 47 for being locked on saw blade cover 45, the second end 464 of connecting rod 46 is by one second pivot 48 It is hubbed at the second pivoting portion 37 of slide cover 35.

In operation, user by handle 49 first by saw arm 41 towards workbench 20 direction push, when saw blade 42 by The drive of saw arm 41 and when being deflected from extreme higher position P1 as shown in Figure 3 towards extreme lower position P2 as shown in Figure 4, the of connecting rod 46 One end 462 can generate the strength for pulling saw blade cover 45 by the clamping relationship between fixing piece 47, allow saw blade cover 45 Beginning pivots and gradually increases the exposed parts of saw blade 42 with respect to saw blade 42.When saw arm 41 is located at extreme lower position as shown in Figure 4 When P2, the second end 442 of the holding part 44 of saw arm 41 is located in the storage tank 34 of fixed seat 31, and user at this time can be saturating Handle 49 is crossed to operate two sliding bar 32, make entire sawing unit 40 by two sliding bar 32 relative to workbench 20 before and after It is mobile, shown in Fig. 5, i.e. using the exposed parts of saw blade 42 to being placed in workbench 20 during sawing unit 40 moves Workpiece carry out Cutting indexes.

It can be seen from the above, the present invention circular sawing machine 10 can allow sawing unit 40 identical sawing stroke lower shortening from The distance that fixed seat 31 is stretched out, can so effectively reduce the whole volume of timber and torque arm length shortens and reduces produced when using Shaking problem, to reach increase sawing precision the effect of.In addition, the connecting rod that the circular sawing machine 10 of the present invention is provided can match The lifting of saw arm 41 is closed to pull saw blade cover 45 to generate pivot, to achieve the purpose that increase start smooth degree.

Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect Describe in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the protection of the present invention Within the scope of.
