[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a foldable and portable timber felling and cutting machine, including a cutting machine body 1. The cutting machine body 1 is provided with an assembly support plate 2 for easy support of various components. The left end face of the assembly support plate 2 has semi-circular head blocks with front and rear through holes for easy installation of a folding plate 3 via a fixed shaft. The top right end face of the assembly support plate 2 has a strip plate with upper and lower through holes at both ends for easy insertion of a handling gripping rod 6 and locking it with a nut. The top end face of the assembly support plate 2 has threaded blind holes on both sides for easy installation of a log cutting machine 5 via bolts. The front end face of the assembly support plate 2 has a bearing groove in the middle for easy installation of a folding fixing rod 7 via a bearing. A folding plate 3 is installed between the semi-circular head blocks of the assembly support plate 2 via a fixed shaft for easy folding and unfolding. The right end face of the folding plate 3 has a semi-circular head strip with front and rear through holes for easy installation of the assembly support plate 2 via a fixed shaft. The left end face of the folding plate 3 is provided with a handle rod in the front-to-back direction for easy gripping, handling and flipping. The left end of the front face of the folding plate 3 is provided with a folding blind hole to facilitate the insertion of the folding locking button 8 to prevent flipping when the folding plate 3 is folded. The right side of the folding blind hole of the folding plate 3 is provided with an unfolding blind hole to facilitate the insertion of the folding locking button 8 to prevent flipping when the folding plate 3 is unfolded. The right side of the folding plate 3 has a rectangular hole that runs through the front and back directions to facilitate the placement of the log conveying roller 4 inside. The top of both ends of the rectangular hole of the folding plate 3 is provided with a semi-circular plate with a through hole in the front and back directions to facilitate the installation of the log conveying roller 4 through the fixed shaft. The log conveying roller 4 is installed between the semi-circular plates of the folding plate 3 through the fixed shaft to facilitate the rotation of the log conveying roller 4. The center of the log conveying roller 4 has a through rotating hole to facilitate the installation and rotation of the log conveying roller 4 through the fixed shaft. The outer circumference of the log conveying roller 4 has a V-shaped groove to facilitate the movement of the log inside.

[0028] The assembly support plate 2 has a log cutter 5 bolted to the top center for easy log cutting. The bottom fixing plate of the log cutter 5 has through-holes at all four corners for bolt fixation. A through-hole in the center of the bottom fixing plate allows the cutter blade to enter during cutting. A handling gripping rod 6 is secured to the top of the strip plate of the assembly support plate 2 with a nut for easy handling of the cutter body 1. The handling gripping rod 6 has an inverted U-shaped structure for easy hand gripping. A limit ring plate is provided on the lower outer circumference of the handle 6 for insertion into the assembly support plate 2 for positioning. Threads are provided on the lower outer circumference of the limit ring plate for easy nut insertion. The bearing groove of the mounting plate 2 is equipped with a folding fixing rod 7, which is installed through the bearing. The folding fixing rod 7 can be flipped through the bearing. A fixing post is set at the rear right end of the folding fixing rod 7, which can be installed through the bearing. The left end face of the folding fixing rod 7 is provided with an internal threaded cylinder in the front-to-back direction, which can be installed through the thread. The folding locking button 8 is installed inside the internal threaded cylinder of the folding fixing rod 7, which can be used to prevent the flipped folding plate 3 from flipping over after being flipped and unfolded. A threaded post is set at the rear of the folding locking button 8, which can be installed through the thread. The folding locking button 8 can be inserted into the folding blind hole and unfolding blind hole of the flipped folding plate 3. The front end face of the threaded post of the folding locking button 8 is provided with a rotating post with an anti-slip groove, which can be used to rotate the folding locking button 8 to prevent slippage.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, such as Figure 1 As shown, the cutting machine body 1 is in the unfolded state. At this time, the assembly support plate 2 and the flip-folding plate 3 are on the same horizontal plane. The folding locking button 8 on the folding fixing rod 7 is inserted into the unfolding blind hole of the flip-folding plate 3. Thus, the flip-folding plate 3 is unfolded and prevented from tipping over by the folding locking button 8 and the folding fixing rod 7. Then, the log is placed on the log conveying roller 4 and pushed to the right to the cutting position of the log cutting machine 5 for cutting. The rotation setting of the log conveying roller 4 solves the problem of the log sliding on the cutting machine support plate, which causes large resistance when the log moves. Figure 1As shown, when the cutting machine body 1 is folded and stored, the folding locking button 8 is rotated to engage with the folding fixing rod 7 via a threaded engagement. This causes the folding locking button 8 to move forward through the threaded engagement, disengaging it from the blind hole of the flip-over folding plate 3. This releases the anti-flipping mechanism on the flip-over folding plate 3. The flip-over folding plate 3 is then flipped upwards at a 90-degree angle and the folding fixing rod 7 is flipped upwards so that the folding locking button 8 aligns with the blind hole of the flip-over folding plate 3. The folding locking button 8 is then rotated to engage with the threaded engagement of the folding fixing rod 7, causing the folding locking button 8 to move backwards through the threaded engagement and insert into the blind hole of the flip-over folding plate 3. This prevents the flip-over folding plate 3 from folding, as shown in the diagram. Figure 4 As shown, this allows the cutting machine body 1 to be folded and stored. When the cutting machine body 1 is moved, the cutting machine body 1 can be lifted and moved by holding the handle of the flip-folding plate 3 and the crossbar of the transport gripping rod 6, which solves the problem that the cutting machine's support plate is a single piece, making the process of moving the cutting machine difficult.

[0031] Example 2: The difference from Example 1 is that the outer circumferential surface of the crossbar of the handling grip bar 6 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the crossbar of the handling grip bar 6 and the hand, and preventing the hand from slipping on the outer circumferential surface of the crossbar of the handling grip bar 6.

[0032] Example 3: The difference from Example 1 is that the outer circumferential surface of the rotating column of the folding locking button 8 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the rotating column of the folding locking button 8 and the hand, and preventing the folding locking button 8 from slipping when rotated.
