Working principle of the present invention:

Referring to the accompanying drawings, when it is necessary to cut with the horizontal positioning bar square 4 as the positioning baffle, first place the multi-functional folding saw table in a horizontal position, and then manually fix the square steel body 525 on the right side of the lifting seat 522 and the long groove square tube. Loosen the fastening nut 529, shake the rocker 93 on the saw table to the left, and move the chain on the sprocket to the left through the longitudinal transmission shaft 9 on the rocker 93, thereby driving the transmission chain in the square tube with a long groove on one side 526 and the square steel body 525 and the lifting seat 522 on it move to the left, and when the square steel body 525 and the lifting seat 522 moved to the inclined surface of the lifting track 523, the lifting seat 522 continued to move horizontally to the left, and the lifting seat 522 The elevating shaft 521 and the vertical positioning bar side 5 on it move downward along the inclined surface of the lifting rail 523 through a slide pin 520, and during the descending process of the vertical positioning bar side 5, it presses the left jumping arm of the V-shaped jumping arm 419. Down, the longitudinal positioning bar side 5 is in the same horizontal position as the movable push plate 3. Simultaneously, the right jumping arm of V-shaped jumping arm 419 rises, and the hook 418 on the telescopic pull rod 414 pushes away from the pipe wall end of the lateral positioning bar side 4, and at this moment, the telescopic pull rod 414 and the long connecting rod 410 move to the right under the elastic force of the spring. Movement, respectively expand the two "eight"-shaped connecting pieces 413 at the front end of the telescopic pull rod 414 and the two "eight"-shaped connecting pieces 413 at the front end of the long connecting rod 410 to the two "one"-shaped connecting pieces 413, so that the lifting positioning pin 412 slides out from the lifting positioning pin seat 411, realizing the rise of the horizontal positioning bar 4, and its rising height is 2.5 cm; at this time, the movable push plate 3 is out of the locking position, and the sheet material to be cut is placed on the movable push plate 3, use the raised horizontal positioning bar 4 as a reference baffle, and use the scale 40 on the movable push plate 3 as a measuring tool. After setting the size to be cut, you can push it forward or backward The movable push plate 3 moves on a vertical and horizontal linear track, thereby realizing the longitudinal advance and retreat of the movable push plate 3 to cut the sheet. , in order to ensure safety and reliability and realize the cutting of the maximum stroke, the maximum cutting plate width of the present invention is 1.05M, and the cutting plate angle is 90 degrees.

Referring to the accompanying drawings, when it is necessary to use the longitudinal positioning strip 5 as the baffle for precise cutting, first pull the pull ring 42 on the telescopic pull rod 414 to the left to make the spring contract and the telescopic pull rod 414 and the long connecting rod 410 move to the left to drive the telescopic The connecting piece 413 at the front end of the pull rod 414 and the long connecting rod 410 moves back, so that the lifting positioning pin 412 is inserted into the hole of the cantilever arm of the lifting positioning pin seat 411. The horizontal position is fixed, and now according to the actual situation, the rocker 93 on the right side of the saw table can be shaken to the right, so that the transmission chain 526 on the front and rear left and right sprockets 527, 528 on the right longitudinal transmission shaft 9 is moved to the right, thereby Drive the transmission chain 526 and the square steel body 525 and the lifting seat 522 on it to move to the right, and when the lifting seat 522 is in the leftmost starting position, along with the transmission chain 526 Move to the right, to make the square steel body 525 on the drive chain 526 in the front and rear long groove square tubes, the lifting seat 522 also move to the right along the long groove square tube, so that the lifting in the lifting seat 522 outside the long groove square tube The sliding pin 520 outside the shaft 521 rises to the table top of the movable push plate 3 along the front and rear oblique lifting rails 523. The scale 40 on the table of the movable push plate 3 is a measuring tool, and the vertical positioning bar 5 is used as a reference baffle, and the exact size of the plate cutting is set according to the distance moved to the right or left, so as to realize the purpose of automatic position control .

Referring to the accompanying drawings, after the above-mentioned horizontal positioning bar square 4 and vertical positioning bar square 5 are adjusted, the height of the working center of the circular saw blade 6 is correctly adjusted, and the dust-proof angle of the dust-proof baffle 68 is adjusted, and the dust-proof bag is installed. 69. Check the control switch 8 on the right side of the bracket body 1.

Referring to the accompanying drawings, in order to facilitate the handling, maintenance, repair and the thickness of the required plate cutting, the circular saw blade 6 in the saw kerf 61 can be adjusted. The hand-twisted nut on the bolt in the groove is loosened, and the bolt passed by one end of the motor base 64 slides down along the long groove of the strut 66, so that the motor base 64 rotates around the rotating shaft fixed on the rear cross beam 65, so that the circular saw The sheet 6 lifts up and down from the sawing kerf 61 to achieve cutting the thickness of the plate and facilitate handling.

See accompanying drawing 1, when it is necessary to transport the saw table to another construction site, the fixing screws on the support sleeve can be loosened, and the outrigger 7 can be folded inwardly under the beam through the diagonal support rod, and the height of the saw table after folding is Only 280CM. The shock-absorbing pad 73 that is enclosed within supporting leg 7 feet can effectively prevent floor abrasion, increases the adhesion of saw table and reduces vibration.

When it is necessary to carry the saw table upstairs, the foldable lifting handles 71 on both sides of the support body 1 are opened to 90°. At this time, the saw table can be moved sideways to facilitate ladders and doors.

Referring to the accompanying drawings, the drawer 72 is provided with a dust cover and hangs on the left side of the support body 1. The drawer 72 is 500MM long, 400MM wide, and 110MM high.

See the attached picture, in order to realize the smooth, smooth, wear-resistant and increase the rigidity of the table top, use the five-prong wood-based board as the bottom plate, fix it with screws, and paste the 0.8MM thick frosted stainless steel plate with glass glue on it. .

Referring to the accompanying drawings, in order to improve the working environment, a dust-proof baffle 68 is established above the circular saw blade 6, and a dust-proof bag 69 is established below the table. The dust-proof baffle 68 and the dust-proof bag 69 can be easily disassembled and cleaned. In order to realize the flexible positioning and sliding performance of the movable push plate 3 and achieve a better dust-proof effect, the bearings used in the movable push plate 3 all adopt bearings with dust-proof covers.

Referring to the accompanying drawings, the surface of the support body 1 is manufactured by a spray-painting process after derusting treatment.
