Meanwhile, the center of the arc of the sliding hole 11 is located in the extending direction of the rod body 10, and the middle of the sliding hole 11 is close to the front and the left and right sides are both close to the back. Of course, the middle of the slide hole 11 can be moved backward and the left and right sides can be moved forward according to different requirements. Thus, when in use, a rotating disc (not shown in the figure) is fixed on a power output shaft (not shown in the figure) of a motor (not shown in the figure) positioned at the lower part of the rod body 10, a rocking handle 100 is arranged at the non-axial center position of the rotating disc, the rocking handle 100 is clamped in the sliding hole 11, and the rotating disc can drive the rod body 10 to reciprocate in the front-back direction after rotating. The slide hole 11 is arc-shaped, so that the speed of the rod 10 moving forward and backward can be changed to a certain extent. For example, the instantaneous speed is relatively slow when moving forward and relatively fast when moving backward. So, be convenient for improve the efficiency of saw blade during operation. Meanwhile, when the saw blade moves forwards, the friction between the rocking handle 100 and the sliding hole 11 is relatively small, so that the rod body 10 can be ensured to be soft when sliding, and the service life of the saw blade can be effectively prolonged.

Optimizing:

this holder does: the front end of the rod body 10 is provided with a socket 12 with a forward opening and a square cross section, and 2 opposite side walls of the socket 12 are provided with at least 2 positioning holes 121 and pressing screw holes 122 located between the positioning holes 121. In this embodiment, the socket 12 may be formed on 2 opposite side walls, such as a left side wall and a right side wall of the socket 12. Meanwhile, 2 clamping plates 20 with square cross sections are penetrated in the insertion opening 12. The sum of the thicknesses of the 2 clamping plates 20 in the left-right direction should be smaller than the width of the insertion hole 12 in the left-right direction so that there is a gap between the 2 clamping plates 20 enough for the saw blade to be inserted. Obviously, in the present embodiment, 2 splints 20 are arranged one left and one right. The outer side surface of the clamping plate 20 is provided with positioning screw holes 21 aligned with the positioning holes 121 in pairs and conical pits 22 aligned with the pressing screw holes 122.
