The first embodiment is as follows:

referring to fig. 1 and 2, the present invention relates to a safety saw for children, which comprises a saw blade 1, a saw blade support frame 2 for fixing the saw blade 1, a driving mechanism capable of driving the saw blade support frame 2 to move in a reciprocating manner along the saw blade 1, and a fixing frame 7. The drive mechanism comprises a cam 3 and a roller 4 provided on the blade support 2. The cam 3 is rotatably arranged on the fixed frame 7. The roller 4 cooperates with the cam 3 to drive the saw blade support 2 to traverse back and forth in the sawing direction of the saw blade 1. The cam 3 is provided with a convex driving piece 5 which can drive the cam to rotate at one end. This embodiment saw cuts through setting up cam 3 and 4 cooperation drive saw blade support frame 2 and the reciprocal excursion of saw blade 1 of roller, and it is rotatory through 5 drive cams of protruding driving piece 3, and it is more convenient to use, and the security is higher during the use, and the staff need not to contact saw blade 1, is fit for infant, children and uses.

Referring to fig. 1 and 2, the male driving member 5 is a hand lever. Through driving the cam 3 in a simple mode of shaking the rotary rod, the longer force arm is utilized to generate larger power, practical operations such as wood sawing, plastic bottle sawing and the like are easily completed, and the use is more labor-saving and safer.

Referring to fig. 1 and 2, the cam 3 is a spiral groove cam. The cam 3 is provided with a cam groove 31 which is connected end to end and is in a closed ring shape. The roller 4 is slidably disposed in the cam groove 31. Through setting up spiral setting and end to end's cam groove 31, cam 3 can drive roller 4 when rotatory and swing along cam groove 31 to the production can drive the reciprocal sideslip of saw blade support frame 2 and saw blade 1, and the drive is more laborsaving convenient, and it is more convenient to control.

Example two:

referring to fig. 1 and 2, two saw blade support rods 21 are disposed at the lower side of the saw blade support frame 2 in parallel. The saw blade 1 is transversely arranged between the two saw blade support bars 21. The end of the saw blade 1 is provided with a sliding sleeve 11 which can be matched with the saw blade support rod 21. The sliding sleeve 11 is slidably sleeved on the saw blade support rod 21. The saw blade support bar 21 is also sleeved with a spring 22 which can drive the sliding sleeve 11 to slide towards the tooth surface end of the saw blade 1 along the saw blade support bar 21. The spring 22 is arranged to be matched with the sliding sleeve 11 to drive the saw blade 1 to move towards the tooth surface side, so that the tooth surface of the saw blade 1 can be always attached to the surface of an object to be sawn when the saw blade works, and the sawing efficiency is improved.

Referring to fig. 1 and 2, the fixing frame 7 includes a bottom plate 71. The cam 3 is fixed on the bottom plate 71 through a cam support bracket 32. The cam 3 is rotatably connected to the base plate 71.

Referring to fig. 1 and 2, a bottom plate 71 on the lower side of the saw blade 1 is provided with a saw dust falling groove 711 which can be matched with the saw blade 1. The sawdust falling groove 711 is arranged to facilitate collection of sawdust, and the environment is prevented from being affected by scattered sawdust.

Referring to fig. 1 and 2, the fixing frame 7 further includes an upper frame body 72 fixed on the bottom plate 71, and the saw blade 1, the saw blade support frame 2, and the driving mechanism are disposed in the upper frame body 72. The side of the upper frame 72 is provided with a side opening 721 for the material to extend into the lower side of the saw blade 1. The setting up of support body 72 can improve the security, thereby avoids the infant to contact the saw blade and reduces injured risk, sets up side opening 721 and is convenient for stretch the object that needs saw cutting to saw blade 1 downside.

Referring to fig. 1 and 2, a position-limiting sleeve rod 8 extending axially away from the end of the cam 3 is arranged on any one of the cam supporting frames 32. A hollow sliding cavity is arranged in the limit sleeve rod 8. The saw blade support frame 2 is provided with a first limit slide bar 24 which can be connected with the slide cavity inside the limit sleeve bar 8 in a sliding way. And (5) setting. The first limit slide bar 24 of the saw blade support frame is matched with the limit sleeve bar 8 to limit the reciprocating transverse moving positions of the saw blade support frame 2 and the saw blade 1, so that the deviation is avoided. The sliding cavity in the preferable limit sleeve rod 8 can be in an irregular shape such as a square shape, a polygon shape and the like, so that the first limit sliding rod 24 of the saw blade support frame is prevented from rotating in the sliding cavity.

Example three:

referring to fig. 3 and 4, a sliding sleeve stopper 23 for cooperating with the sliding sleeve 11 to limit the sliding sleeve 11 on the saw blade support rod 21 is detachably disposed on the saw blade support rod 21. Avoid sliding sleeve 11 to drop and lead to saw blade 1 to drop, it is more convenient to change saw blade 1.

Referring to fig. 3 and 4, two ends of the saw blade support frame 2 are respectively provided with a plurality of second limit slide bars 25 of the saw blade support frame extending towards the two ends. The bottom plate 71 is provided with a limit baffle 9 which can be matched with the second limit slide bar 25 of the saw blade support frame. And a position-limiting slide hole which can be matched with the second position-limiting slide rod 25 of the saw blade support frame is arranged at the position, corresponding to the second position-limiting slide rod 25 of the saw blade support frame, of the position-limiting baffle 9. The second limit slide bar 25 of the saw blade support frame is slidably arranged in the limit slide hole. The second limit slide bar 25 of the saw blade support frame is matched with the limit slide hole to further limit the reciprocating transverse moving position of the saw blade support frame 2 and the saw blade 1, so that the deviation is avoided.

The utility model discloses the working process:

the utility model relates to an infant is with safe saw in the course of the work, the commodity circulation that will saw cut stretches into saw blade 1 downside through the side opening 721 of last support body 72 side, through the mode drive cam 3 of waveing protruding driving piece 5, cam 3 and 4 cooperation drive saw blade support frames of roller 2 and the reciprocal excursion of saw blade saw cut, spring 22 can drive saw blade 1 to flank of tooth side motion with the 11 cooperations of sliding sleeve, thereby make saw blade 1 can laminate all the time at the during operation flank of tooth and saw the object surface.

The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
