[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] As attached Figure 1 To Attachment Figure 4 As shown:

[0027] Embodiment 1: The utility model provides a bamboo sawing device for forestry, comprising a bamboo sawing mechanism 1, including a chain saw body 101, a chain saw head 102 arranged at the front end of the chain saw body 101, and a control handle 103 arranged at the rear end of the chain saw body 101; a protective mechanism 2, comprising a U-shaped protective shell 201 slidably arranged on the chain saw body 101, protective side plates 202 slidably arranged on both sides of the U-shaped protective shell 201, and a protective baffle 203 rotatably arranged on the top of the U-shaped protective shell 201; and a limiting mechanism 3, arranged on the U-shaped protective shell 201.

[0028] Specifically, tooth plates 208 are installed on both sides of the inner surface of the U-shaped protective shell 201 , and gears 2010 are installed on both sides of the chain saw body 101 at the top and bottom of the tooth plate 208 .

[0029] There are eight gears 2010 , and all of the eight gears 2010 are meshed with the toothed plate 208 .

[0030] Furthermore, a gripping block 207 is installed on the outer side of the protective side plate 202, guide rods 205 are installed on both side surfaces of the U-shaped protective shell 201 at both ends of the protective side plate 202, and sliders 206 are installed at both ends of the protective side plate 202, and the movement trajectory of the guide rod 205 is adapted to that of the slider 206.

[0031] Furthermore, a tilting seat 209 is installed on the top of the chain saw body 101 at the rear end of the protective baffle 203 , and a magnetic attraction block 204 is installed on the top of the protective baffle 203 .

[0032] As can be seen from the above, when the worker is sawing bamboo, he or she holds the control handle 103 to pick up the device, then pulls the U-shaped protective shell 201 toward the rear end of the device to expose the chain saw head 102, then brings the chain saw head 102 into contact with the bamboo to be cut, and controls the chain saw body 101 to be turned on so that the chain saw head 102 can be used to saw bamboo. The U-shaped protective shell 201 will shield and protect the worker's hands during the bamboo sawing process to prevent the device from being lost or accidentally injured due to external force collision during the bamboo sawing process. After the bamboo sawing work is completed, the U-shaped protective shell 201 is pushed toward the front end of the device. The protective shell 201 is arranged to overlap with the chain saw head 102, so that the chain saw head 102 is shielded and protected when not in use, thereby improving the safety of use and extending the service life of the device. When the U-shaped protective shell 201 moves, it will drive the tooth plate 208 to move synchronously, and the tooth plate 208 will drive the gear 2010 to rotate by meshing with the gear 2010. Therefore, when the U-shaped protective shell 201 stops moving, the meshing friction between the eight gears 2010 and the tooth plate 208 limits the position of the U-shaped protective shell 201, thereby improving the stability of use, and when sawing bamboo, it can be adjusted according to the worker's The operator needs to hold the gripping block 207 and then push the protective side plate 202 downward. The slider 206 will slide on the guide rod 205 to limit and guide the protective side plate 202, increase the range of motion of the operator's wrist, and facilitate the operator's use. When the U-shaped protective shell 201 moves toward the rear end of the device, it will drive the protective baffle 203 to move synchronously. When the protective baffle 203 contacts the tilting seat 209, the tilting seat 209 will generate an upward oblique thrust on the protective baffle 203 to lift the protective baffle 203, so that the protective baffle 203 is in an inclined state, thereby During work, the sawdust generated by sawing bamboo is blocked to prevent it from directly splashing onto the hands of the staff, to prevent the staff from being affected, and to facilitate the use of the staff. When the U-shaped protective shell 201 is pushed toward the front end of the device, the protective baffle 203 will be driven to move synchronously. When the protective baffle 203 is separated from the tilting seat 209, the protective baffle 203 will rotate downward due to the deadweight of the magnetic block 204 until the magnetic block 204 contacts and adsorbs the U-shaped protective shell 201, so as to limit the position of the protective baffle 203, reduce the area occupied by the device, and increase the protection area of ​​the U-shaped protective shell 201.

[0033] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the limiting mechanism 3 includes a roller 302 arranged at the rear end of the protective baffle 203, a blocking block 303 is installed on the U-shaped protective shell 201 at the front end of the protective baffle 203, and limiting blocks 301 are installed on both side surfaces of the inner side of the U-shaped protective shell 201 at the rear end of the control handle 103.

[0034] As can be seen from the above, when the U-shaped protective shell 201 moves toward the rear end of the device together with the protective baffle 203, the roller 302 will contact the tilting seat 209 in advance, and the roller 302 will reduce the contact resistance between the protective baffle 203 and the tilting seat 209 by its own rolling, thereby improving the deployment efficiency. The blocking block 303 and the limit block 301 will limit the range of movement of the U-shaped protective shell 201 to prevent it from directly sliding out from the front or rear end of the device and detaching from the chain saw body 101. When the U-shaped protective shell 201 moves to the final position toward the rear end of the device, the blocking block 303 will contact the upper surface of the protective baffle 203, and then the protective baffle 203 will be clamped in the middle by the blocking block 303 and the tilting seat 209, thereby improving the stability of the protective baffle 203 during operation and increasing the protective effect.
