Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

The embodiment is as follows:

as shown in fig. 1-4, the single-hand saw comprises a base 1, a handheld rod 2 and a cutting assembly 3, the handheld rod 2 is fixedly connected to the upper surface of the base 1, the cutting assembly 3 is arranged at one end, far away from the base 1, of the handheld rod 2, the cutting assembly 3 comprises a shell and a cutting tool, the shell is fixedly connected with one end of the handheld rod 2, the cutting tool is located in the shell, a protection plate 4 is arranged on one side of the cutting assembly 3, a pulling rod 5 is arranged on one side face of the protection plate 4, an insertion rod 6 located in the protection plate 4 is fixed at one end of the pulling rod 5, and one end, far away from the pulling rod 5, of the insertion rod 6 is inserted into the shell.

The working principle of the above technical scheme is as follows: when handheld pole 2 cuts the operation, the piece accessible guard plate 4 that the cutting produced this moment blocks the protection, and the piece that prevents to splash causes the scratch to staff's skin, and when not using

guard plate

4, 5 application of force drive inserted bar 6 take out from the shell is moved in the handheld pulling of accessible, can hand the installation of 4 application of force cancellation of guard plate and shell afterwards, has realized the effect of the protection of being convenient for, is favorable to having increased the guard effect.

In another embodiment, as shown in fig. 1 and 4, a protective sleeve 11 is sleeved on the surface of the handheld rod 2, a plurality of protective pads 12 are fixed on the surface of the protective sleeve 11 and are uniformly distributed, and the protective pads 12 are arc-shaped plates and made of rubber.

When the staff holds the handheld pole 2 in hand and carries out the operation, the accessible lag 11 with the protection of protection pad 12 have increased the frictional force of handheld pole 2 with hand, prevent that the staff hand from slipping with the contact surface frictional force of handheld pole 2 not good, leading to the staff hand to slide and cause the accident.

In another embodiment, as shown in fig. 2 and 3, two limiting plates 7 are fixed on the surface of the insertion rod 6, the two limiting plates 7 are symmetrically arranged, a groove corresponding to the insertion rod 6 and the limiting plate 7 is formed in the surface of the outer shell, and the insertion rod 6 and the limiting plate 7 are located in the groove and used for limiting the protection plate 4.

Through setting up limiting plate 7, be favorable to having increased the result of use, prevent the condition that the guard plate 4 overturn when receiving the driving force from appearing, lead to the protecting effect not good, influence the result of use.
