[0027] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0028] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0030] An embodiment of this utility model provides a rail saw, such as Figure 1-8 As shown, it includes:

[0031] The chainsaw body 100 includes a motor, a fan structure 120 for heat dissipation, and a saw blade assembly 130 connected to the output shaft of the motor. The fan structure 120 includes a fan blade 121 and a deflecting air duct 122 that cooperates with the fan blade 121. The deflecting air duct 122 is used to change the exhaust direction of the fan blade 121.

[0032] The track base 200 and the chainsaw body 100 are hinged to the track base 200 for cutting.

[0033] The electric motor serves as the power source, providing rotational power to the saw blade. The fan structure 120 is used for heat dissipation, preventing the motor from overheating during prolonged operation. The fan structure 120 includes a fan blade 121 that generates airflow through rotation, and a deflector duct 122 for changing the direction of the airflow generated by the fan blade 121. The saw blade assembly 130 is connected to the output shaft of the motor for cutting material. The chainsaw body 100 is hinged to the track base 200, allowing the chainsaw body 100 to be angled on the track base 200 for cutting operations. The cooperation of the fan blade 121 and the deflector duct 122 changes the exhaust direction, preventing the motor's exhaust vent from directly blowing hot air onto the operator's hands or other body parts.

[0034] In some embodiments, the motor has a fan slot 123 with an outlet, and the deflection duct 122 is a guide duct 124, with the outlet of the fan slot 123 connected to the guide duct 124.

[0035] The fan slot 123 is located around the fan blade 121 and corresponds to the rotation direction of the fan blade 121. It is a channel surrounding the fan blade 121, used to collect the airflow generated when the fan blade 121 rotates. The main function of the fan slot 123 is to initially gather and guide the air generated by the fan blade 121, allowing it to flow in a specific direction rather than spreading randomly. The air guide slot 124 is connected to the fan slot 123 and is used to change the direction of the airflow. It is usually a channel with a certain angle or shape, which can guide the airflow in the fan slot 123 to a specific location. The main function of the air guide slot 124 is to change the direction of the airflow, allowing it to be precisely blown towards a predetermined area. Through the cooperation of the fan slot 123 and the air guide slot 124, the airflow can be efficiently guided to the predetermined location. This design integrates the fan blade 121 with the deflecting air duct 122, making the entire chainsaw body 100 structure more compact. By adjusting the shape and angle of the air guide slot 124, the airflow direction can be flexibly changed to adapt to different heat dissipation requirements.

[0036] Furthermore, the air guide slot 124 is arc-shaped, and the outer periphery of the air guide slot 124 is tangent to the outer periphery of the fan slot 123.

[0037] The air guide slot 124 is designed in an arc shape, matching the rotation direction of the fan blade 121 and the natural flow path of the airflow. The arc-shaped air guide slot 124 smoothly guides the airflow, reducing resistance and turbulence during turning, thereby improving airflow efficiency. The outer periphery of the air guide slot 124 is tangent to the outer periphery of the fan slot 123, meaning there is no abrupt change at the connection point, allowing airflow to smoothly transition from the fan slot 123 to the air guide slot 124. This design makes the overall structure of the turning duct 122 more compact, saving space and improving overall integration.

[0038] Furthermore, the width of the air guide 124 gradually increases in the air outlet direction.

[0039] As the airflow enters the air guide duct 124 from the fan duct 123, the airflow velocity gradually decreases due to the gradually increasing cross-sectional area of ​​the air guide duct 124, reducing the impact of the airflow on the operator. Because the airflow gradually slows down in the air guide duct 124, its flow becomes smoother, reducing noise generated by airflow impact and turbulence.

[0040] In some embodiments, the air outlet 128 of the air guide duct 124 is arranged downwards.

[0041] The air outlet 128 of the air guide 124 is arranged downwards, so that the airflow generated by the fan blade 121 will not blow towards the operator.

[0042] In some embodiments, the track base 200 includes a base plate 210 for pressing down on the workpiece, with the air outlet 128 of the air guide 124 facing the base plate 210. The base plate 210 is used to press down on the workpiece, ensuring the stability and safety of the material during cutting.

[0043] The air outlet 128 of the air guide duct 124 is designed to face the base plate 210 of the track saw. This means that the airflow generated by the fan blade 121, after being guided by the fan duct 123 and the air guide duct 124, is finally blown towards the base plate 210, effectively preventing the airflow from blowing towards the operator.

[0044] In some embodiments, the fan blade structure 120 further includes a first mounting shell 125 and a second mounting shell 126 that cooperates with the first mounting shell 125. The first mounting shell 125 is used to fix the motor, the fan blade 121 is connected to the motor, and the first mounting shell 125 and the second mounting shell 126 form a steering duct 122.

[0045] The first mounting housing 125 contains mounting positions and support structures for fixing the motor. The second mounting housing 126 cooperates with the first mounting housing 125 to jointly form the deflecting air duct 122. The internal structure of the second mounting housing 126 matches the shape of the fan blade 121 and the design of the deflecting air duct 122 to ensure that the airflow can flow along a predetermined path. The second mounting housing 126 may include structures such as air guide slots 124 and fan slots 123 to guide the direction and speed of the airflow.

[0046] Furthermore, the first mounting housing 125 is provided with a motor mounting groove 127 for fixing the motor, and the steering air duct 122 is connected to the motor mounting groove 127.

[0047] The motor mounting slot 127 is a groove inside the first mounting housing 125 used to fix the motor. Its function is to ensure the motor remains stable during operation and to precisely connect with the fan blade 121. The shape of the motor mounting slot 127 matches the shape of the motor, typically a circular or elliptical slot, which tightly encloses the motor and reduces vibration. The mounting slot is designed with threaded holes, clips, or other fixing structures to securely install the motor inside the first mounting housing 125. The deflecting air duct 122 is connected to the motor mounting slot 127, meaning that the inlet of the deflecting air duct 122 is connected to the motor mounting slot 127. This design allows the airflow generated by the fan blade 121 to directly enter the deflecting air duct 122 from around the motor mounting slot 127.

[0048] In some embodiments, the base plate 210 is provided with a groove 220 that mates with the track, and the track base 200 further includes a clamping device 230 for clamping the track.

[0049] The base plate 210 is provided with a groove 220 that mates with the track. The shape and size of the groove 220 match the track, allowing the track saw to slide smoothly on the track. A clamping device 230 is used to fix the track to the base plate 210, ensuring that the track will not shift during the cutting process. The clamping device 230 can be adjusted according to the size and shape of the track to accommodate different tracks.

[0050] Furthermore, the clamping device 230 includes two clamping blocks 240 respectively disposed on two side walls of the slide groove 220 and an adjusting assembly 250 for driving one of the clamping blocks 240 toward the other clamping block 240.

[0051] The clamping device 230 includes two clamping blocks 240, each disposed on the side wall of the slide 220. The clamping blocks 240 clamp the track by moving closer together, preventing the track from shifting or wobbling during cutting. The adjusting component 250 is used to drive one of the clamping blocks 240 closer to the other, thereby clamping or releasing the track. The adjusting component 250 can be a screw or a knob, and the position of the clamping blocks 240 can be adjusted by manual rotation.

[0052] Furthermore, the adjustment assembly 250 includes a cam 260 that abuts against one of the clamping blocks 240, and as the clamping block 240 rotates from its base circle abutting against the clamping block 240 to its flange abutting against the clamping block 240, the clamping block 240 moves closer to the other clamping block 240.

[0053] The flange and base circle of cam 260 correspond to different radial dimensions, and the contact position between cam 260 and clamping block 240 can be changed by rotating cam 260.

[0054] When the flange of cam 260 abuts against clamping block 240, clamping block 240 is pushed against another clamping block 240, thus clamping the track. When the base circle of cam 260 abuts against clamping block 240, clamping block 240 is released, allowing the track to be freely installed or removed. The design of cam 260 allows users to quickly clamp or release the track with a simple rotation, making operation simple and fast. By adjusting the rotation angle of cam 260, the clamping force can be precisely controlled to adapt to tracks of different sizes and materials.

[0055] In some embodiments, a grip handle is provided on the top of the chainsaw body 100.
