The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.
[0039] The present disclosure provides a guide rail width adjustment device, see Figure 1 The adjusting device is used to adjust the width of the guide rail; the adjusting device includes a base plate 3 and a cam knob 2 and a width adjusting rod 4 that cooperate with each other; the guide rail is arranged at the bottom end of the base plate 3, and the guide rail extends along the first direction; the cam knob 2 is rotatably arranged at the top end of the base plate 3, and the width adjusting rod 4 is rotatably arranged at the bottom end of the base plate 3; the cam knob 2 is used to drive the width adjusting rod 4 to move to adjust the width of the guide rail.
[0040] In the disclosed embodiment, the adjusting device is composed of a cam knob 2, a base plate 3, and a width adjusting rod 4. The cam knob 2 and the width adjusting rod 4 are installed on the base plate 3. The width adjusting rod 4 is driven to rotate by rotating the cam knob 2. The rotation angle of the cam knob 2 determines the adjustment distance of the width adjusting rod 4, thereby realizing precise adjustment of the track width.
[0041] Compared with the existing guide rail width adjustment device, this adjustment device has a simple structure, is easy to operate, and has low cost. Within its adjustment range, it can control the adjustment distance of the width adjustment rod to achieve precise adjustment of the guide rail width and ensure the accuracy of the rail width.
[0042] In one embodiment of the present disclosure, a cam knob 2 and a width adjustment rod 4 are provided at one end of the bottom plate 3, that is, the adjustment device is installed at one end of the bottom plate 3. In this way, the adjustment device can adjust the width of one end of the guide rail on the bottom plate 3.
[0043] In another embodiment of the present disclosure, a cam knob 2 and a width adjustment rod 4 are respectively provided at both ends of the bottom plate 3, that is, an adjustment device is installed at both ends of the bottom plate 3. In this way, the adjustment device can adjust the width of both ends of the guide rail on the bottom plate 3, realize synchronous adjustment of the width of the entire guide rail, and make the width of the guide rail balanced.
[0044] In other embodiments of the present disclosure, more than two cam knobs 2 and width adjustment rods 4 may be evenly installed on the bottom plate 3 , that is, more than two adjustment devices may be evenly installed on the bottom plate 3 .
[0045] In one embodiment of the present disclosure, see Figure 1 The cam knob 2 and the width adjusting rod 4 are eccentrically arranged. In this way, it is convenient for the cam knob 2 to drive the width adjusting rod 4 to rotate.
[0046] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The cam knob 2 includes a cam track 201, which is disposed at the bottom end of the cam knob 2; the cam track 201 is an incomplete annular track;
[0047] The width adjustment rod 4 includes a slider 401, which is disposed at the top of one end of the width adjustment rod 4 close to the cam knob 2; the slider 401 can reciprocate in the cam track 201, so that the slider 401 moves in a second direction perpendicular to the first direction. In this way, by rotating the cam knob 2, adjusting the position of the slider 401 in the cam track 201, and adjusting the rotation angle of the width adjustment rod 4, the adjustment distance of the width adjustment rod 4 can be adjusted, thereby achieving precise adjustment of the guide track width.
[0048] Alternatively, see Figure 1 The first direction is the length direction of the bottom plate 3 , and the second direction is the width direction of the bottom plate 3 .
[0049] Optionally, the length of the cam track 201 is three quarters of the circumference, that is, the angle of the cam track 201 is 270 degrees. In this way, the rotation angle range of the cam knob 2 can be controlled, thereby controlling the adjustment range of the width adjustment rod 4.
[0050] Furthermore, the length of the cam track 201 can be adjusted, that is, the angle of the cam track 201 can be adjusted. In this way, the maximum adjustment range of the width adjustment rod 4 can be adjusted.
[0051] Optionally, the slider 401 may be rotatably connected to the width adjustment rod 4 , so that the friction between the slider 401 and the inner wall of the cam track 201 can be reduced, the service life of the slider 401 and the cam track 201 can be increased, and the cost of the adjustment device can be reduced.
[0052] Optionally, in the first state, the slider 401 is located at one end of the cam track 201 away from the axis of the cam knob 2, and the width adjustment rod 4 is in a horizontal original state; in the second state, the slider 401 is located at one end of the cam track 201 close to the axis of the cam knob 2, and the width adjustment rod 4 is in an inclined state.
[0053] In one example, rotating the cam knob 2 clockwise causes the width adjustment rod 4 to switch from the first state to the second state, thereby achieving positive adjustment of the guide track width; rotating the cam knob 2 counterclockwise causes the width adjustment rod 4 to switch from the second state to the first state, thereby achieving reverse adjustment of the guide track width, thereby restoring the guide track width to its original position.
[0054] Optionally, the cam track 201 and the slider 401 are clearance-matched, and the adjustment distance of the width adjustment rod 4 can be precisely adjusted by adjusting the position of the slider 401 in the cam track 201 .
[0055] In one embodiment of the present disclosure, see Figure 1 The cam knob 2 is rotatably connected to the top of the bottom plate 3 through the screw 1. In this way, the cam knob 2 can be quickly disassembled and assembled, thereby reducing the structural complexity of the adjustment device.
[0056] In one embodiment of the present disclosure, see Figure 1 The width adjustment rod 4 is rotatably connected to the bottom end of the bottom plate 3 through the axial screw 5. In this way, the width adjustment rod 4 can be quickly disassembled and assembled, thereby reducing the structural complexity of the adjustment device.
[0057] In one embodiment of the present disclosure, see Figure 1The guide rails include a first guide rail 6 and a second guide rail 7, and the width of the first guide rail 6 is greater than the width of the second guide rail 7. In this way, the stability of the movement of the track saw can be improved by using two guide rails of different widths.

In this way, the width of the first guide rail 6 and the second guide rail 7 can be adjusted at the same time by the width adjustment rod 4 installed between the first guide rail 6 and the second guide rail 7, thereby improving the guide rail width adjustment efficiency.
[0059] In one embodiment of the present disclosure, see Figure 1 , a mounting sleeve 302 is provided at the top of the bottom plate 3, and the mounting sleeve 302 is located between the first guide rail 6 and the second guide rail 7; the cam knob 2 is coaxially arranged with the mounting sleeve 302 and is rotatably connected, and the cam knob 2 is located in the mounting sleeve 302. In this way, by mounting the cam knob 2 through the mounting sleeve 302, the cam knob 2 and the cam track 201 thereon can be protected, and the service life of the cam knob 2 and the cam track 201 can be increased.
[0060] Optionally, the mounting sleeve 302 is used to form a space in which the cam knob 2 and the width adjustment rod 4 cooperate with each other, and the cam track 201 and the slider 401 move in the space, so that the guide rail width can be adjusted by rotating the cam knob 2 .
[0061] In one embodiment of the present disclosure, see Figure 1 The top of the bottom plate 3 is provided with a slide groove 303 connected with the mounting groove 301, and the slide groove 303 is located in the mounting sleeve 302; the slide groove 303 extends along the second direction, and the slider 401 can reciprocate in the slide groove 303. In this way, the slide groove 303 plays a guiding role, so that the slider 401 moves smoothly in the cam track 201, ensuring the smooth rotation of the cam knob 2, and further ensuring the smooth adjustment of the width of the guide rail.
[0062] Optionally, the width of the slide groove 303 is greater than the diameter of the slider 401 , that is, the slide groove 303 and the slider 401 are clearance-matched. In this way, the slider 401 can move in the slide groove 303 easily.
[0063] Furthermore, when the cam knob 2 rotates and drives the slider 401 to move on the cam track 201 , the slider 401 can move in the slide groove 303 extending along the second direction.
[0064] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The working process of the guide rail width adjustment device is briefly described as follows:
