At this time, the stepless speed change switch 74 can push the push plate 73 and the button 72 to reset.

[0035] Working process: When using this new reciprocating saw, first install the fully charged battery body 2 at the bottom of the fixed body 3 through the buckle and the slot. At this time, the current enters the reciprocating body 1 through the fixed body 3 to connect the power to the reciprocating body 1. Then push the connecting rod 53, and the connecting rod 53 drives the slide plate 52 to move. At this time, the slide plate 52 moves outside the limit ring and the slider 59. At the same time, the slide plate 52 drives the limit block 518 to slide in the limit groove 516 opened in the fixed plate 511. At this time, the limit block 518 pushes the first spring 515 to be compressed on the outside of the slide bar 514. When the distance between the rotating wheels 55 on the upper and lower sides is appropriate, place the saw blade body 4 above the object to be sawed, and then adjust the rotating wheel 55 at the bottom, and then move the reciprocating body 1. The reciprocating body 1 drives the fixing plate 511 to move through the connecting body 56, so that the fixing plate 511 fits on the object to be sawed. At this time, the limiting ring is pushed to move under the action of the first spring 515, and the limiting block 518 drives the slide plate 52 to move. The slide plate 52 drives the rotating wheel 55 to move through the connecting rod 53 and the connecting plate 54, so that the rotating wheel 55 fits with the object to be sawed, so as to clamp the object to be sawed. Then, the switch of the reciprocating body 1 is turned on, and the button 72 is pressed. The button 72 pushes the push plate 73 to move, and the push plate 73 pushes the stepless speed switch 74 to form a passage. At this time, the reciprocating body 1 drives the saw blade body 4 to move back and forth to realize the sawing of the object to be sawed. When the button 72 is pressed, the push plate 73 pushes the vertical rod 766 arranged on the top. The third spring 768 pushes the cross plate 765 to move downward, and the cross plate 765 drives the vertical plate to be inserted into the push plate 73, and the bottom end of the vertical rod 766 is tightly fitted with the rubber strip 78, so as to position the push plate 73, so as to limit the continuously variable speed switch 74, so as to control the running speed of the reciprocating body 1, thereby controlling the running speed of the saw blade body 4. Hold the reciprocating body 1 with one hand other than the main body 6, and push the reciprocating body 1 to move downward. At this time, the reciprocating body 1 drives the saw blade to move downward, so that the saw blade and the object to be sawed come into contact with each other, and the object to be sawed is sawed. When sawing the object to be sawed, the sawing angle and position between the saw blade and the object to be sawed can be adjusted to facilitate the sawing of the object to be sawed. During the adjustment process, the rotating wheel 55 rolls on the surface of the object to be sawed to ensure that the saw blade body 4 and the object to be sawed are always vertically set, reducing the direct contact area between the side of the saw blade body 4 and the object to be sawed, improving the operating efficiency of the saw blade body 4, and facilitating the sawing of objects with high viscosity. After sawing, the movable plate 761 is pushed upward by the rubber plate 769.The movable plate 761 pushes the push rod 763 and the connecting block 764 to move upward through the mounting rod 762, and the push rod 763 pushes the horizontal plate 765 to move upward on the outer side of the guide rod 767, and the horizontal plate 765 drives the vertical rod 766 to move upward until the bottom end of the vertical rod 766 leaves the card slot 77 opened at the top of the push plate 73. At this time, the stepless speed switch 74 pushes the push plate 73 and the button 72 to reset, and the reciprocating body 1 stops running. When it is necessary to saw the sawed object at other angles, turn off the switch of the reciprocating body 1, and then pull the fixed plate 511 in the direction away from the reciprocating body 1, the fixed plate 511 drives the fixed rod 561 to move, and the fixed rod 561 drives the plug 565 to move, and at the same time the card column 567 pushes the baffle 566 on the fixed rod 561 slides, the baffle plate 566 pushes the second spring 569 to be compressed on the outside of the limit column 568, and after the insertion rod 564 moves to the appropriate position, the insertion block 565 is taken out of the fixed frame 562, and then the fixed plate 511 is rotated, and the fixed plate 511 rotates on the outside of the saw blade body 4. After the saw blade body 4 rotates 90°, the fixed plate 511 is moved to the side close to the reciprocating body 1 until the clamping column 567 and the baffle plate 566 do not contact each other, and then the fixed plate 511 is moved downward, and the fixed rod 561 is taken out of the fixed frame 562, and then the saw blade body 4 can directly saw the sawed object at any angle. After the sawing is completed, the fixed plate 511 is installed back to the outside of the saw blade body 4 according to the above reverse process.
