Description of the invention (/) [Detailed description] [Background of the invention] The present invention is the one in the scope of patent application item 1 Reciprocating saw. The British patent GB-PS14 · 6281 published a reciprocating paper whose saw blade has a partially retracted back, which is pressed against a guide roller, so that after the non-retracted area, the retracted area of the back enters the person After guiding the rollers, each longitudinal stroke of the saw blade overlaps with a lateral stroke. In this way, when a vertical stroke, its distance to the tool embedding line will change, that is, when the longitudinal stroke will be embedded deeper in the work or "idling" outside the tool embedding line. In this way, the load of the saw blade in its longitudinal range is not uniform: the area of the tooth that is tougher near the clamping end is more loaded than the area of tooth that is less tough near the tip of the blade. As a result, the life of the saw blade is increased, and the increase in manufacturing cost exceeds the benefits that can be achieved by this saw blade shape. [Advantages of the present invention] Compared to this, the advantages of the reciprocating saw of the present invention having the characteristics of item 1 of the patent scope are: · Compared with this traditional reciprocating saw, it can be cut faster, where The horizontal stroke during a longitudinal stroke is much faster, so the sawdust is loosened so that the sawdust is sent more efficiently. Other advantageous features of the invention can be found in the sub-item of the scope of patent application. [Description of drawings] The following is a detailed description of an embodiment of the present invention with reference to the drawings: The first figure is a side cross-sectional view of the area before the reciprocating saw of the present invention; the second figure is a saw blade for a related reciprocating saw. -3- This paper scale is applicable to China National Standardization (CNS) A4 ^ (210X297mm_)-" tPlease read the notes on the back before filling out this page) Order A7 B7 Central Ministry of Economic Affairs Staff Consumer Cooperative Printing 5.

Description of the invention (1) The side tenon (23) (23 '). The distance between the lowest and highest positions on the back of the waveform is represented by Q. Q determines the horizontal stroke determined by the waveform profile of the blade (32) during sawing. The reciprocating saw of the present invention operates in the above manner: after a drive motor (not shown) is turned on via a 0N / 0 FF switch, the saw blade (22) begins to reciprocate along its longitudinal axis (19). Since the back of the wave (2 8) travels in the groove along the guide groove (3 0) of the guide roller (3 2), the saw blade (22) can correspond to the profile of the back of the wave for horizontal travel. The stroke overlaps with the reciprocating motion. In this way, the vibration tooth embedding effect can be achieved in the work, so that the sawdust is more easily taken away, and the cutting saw efficiency is improved. The transverse travel frequency changes proportionally with the longitudinal travel frequency. Using a higher longitudinal travel frequency can result in a higher transverse travel frequency. Depending on the type of material, the back of the saw blade is designed to be a uniformly raised back or a corrugated pu with a special way of matching, where the cross-section Q defined by the waveform profile is not uniform, and the role of κ to take away the sawdust is most suitable Tonic.
