Saw blade-retractable hand saw

Abstract

The invention discloses a saw blade-retractable hand saw. The saw blade-retractable hand saw comprises a saw blade, a shell, a telescopic spring and a latch device, wherein a saw blade slot capable ofbeing matched with the saw blade is formed in the shell; the saw blade is arranged inside the saw blade slot; the saw blade and the saw blade slot are in telescopic sliding fit connection axially; asaw blade tail block is arranged at the tail end of the saw blade; the telescopic spring is arranged between the saw blade tail block and the side wall of the saw blade slot; the latch device is arranged at the upper end of the shell; the latch device runs through the shell and stretches into the saw blade slot. Through formation of the saw blade slot in the shell, the saw blade can be stored in the saw blade slot through arrangement of the saw blade slot, and the saw blade is drawn out during using; through arrangement of the spring, the saw blade can be conveniently popped out; through arrangement of the latch device, the latch device can be matched with two concave holes in the saw blade so as to limit the saw blade; compared with the conventional technology, the saw blade-retractable hand saw provided by the invention has the advantages as follows: the saw blade can be freely stored into the shell or can freely stretch out of the shell, so that the safety of the saw is improved andthe saw is convenient to store or carry.
