[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a garden pruning saw with high safety. Figure 1-3 A garden pruning saw with high safety comprises an operating rod 1, a saw blade protection assembly 2 is mounted on the operating rod 1, the saw blade protection assembly 2 comprises a connecting seat 201 mounted on the operating rod 1, L-shaped guard plates 202 are mounted on both sides of the connecting seat 201, elastic scrapers 204 are mounted on the inner sides of the two L-shaped guard plates 202, folding saw blades 3 are mounted on the inner sides of the tops of the two L-shaped guard plates 202, the folding saw blades 3 comprise an L-shaped knife seat 301 hingedly mounted on the operating rod 1, and a saw blade 302 is mounted on the L-shaped knife seat 301;

[0021] By adopting the above technical solution, the saw blade 302 can be unfolded and folded into the two L-shaped guard plates 202 fixed on the operating rod 1 through the hinge connection between the L-shaped tool holder 301 and the L-shaped guard plate 202, thereby providing shielding protection for the saw blade 302.

[0022] Reference Figure 1 A fixing sleeve 203 is installed at the lower end of the L-shaped guard plate 202, and the fixing sleeve 203 is sleeved on the operating rod 1. Pin holes are opened on the connecting seat 201 and the fixing sleeve 203, and a pin shaft is installed in the pin hole. The end of the pin shaft passes through the operating rod 1 and is slidably connected with the operating rod 1;

[0023] By adopting the above technical solution, the L-shaped guard plate 202 is firmly fixed on the operating rod 1 through the connecting seat 201 and the fixing sleeve 203 .

[0024] Reference Figure 2 A positioning hole is provided at the corner of the saw blade 302, a locking bolt 303 is slidably installed in the positioning hole, two bolt holes matching the locking bolt 303 are provided on an L-shaped guard plate 202, and two threaded holes matching the locking bolt 303 are provided on an L-shaped guard plate 202, and the distance between the bolt hole and the threaded hole to the hinge point of the saw blade 302 is the same as the distance between the positioning hole and the hinge point of the saw blade 302;

[0025] By adopting the above technical solution, by changing the position of the locking bolt 303 and aligning the positioning hole with the bolt hole and the threaded hole, the L-shaped knife holder 301 is fixed to achieve the deployment and storage of the saw blade 302.
