[0025] like Figure 1-5 As shown in the embodiment, a cutting fixture is characterized by including a connecting rod 11, on which a saw blade 12 is fixedly mounted; both ends of the connecting rod 11 are fixedly mounted on a connecting rod fixing seat 13; the connecting rod fixing seat 13 is fixedly mounted on a mounting plate 14; a telescopic rod 15 is fixedly connected to the mounting plate 14; a driving device 16 is also provided on the mounting plate 14, which is connected to the connecting rod 11 and drives the connecting rod 11 to rotate.

[0026] The connecting rod 11 rotates around its axis, and the saw blade 12 rotates synchronously with the connecting rod 11.

[0027] In this embodiment, there are two connecting rod fixing seats 13, which are arranged opposite to each other; the connecting rod 11 is disposed between the two connecting rod fixing seats 13.

[0028] The drive unit 16 is a rotary motor or a hydraulic motor.

[0029] The drive device 16 drives the connecting rod 11 to rotate, and the saw blade 12 rotates synchronously with the connecting rod 11 to cut the object to be cut.

[0030] The telescopic rod 15 enables remote operation of the saw blade 12 for cutting; it is suitable for cutting high-level tree branches or grooving high-level walls, thus expanding the application range of this utility model product's cutting fixture.

[0031] Furthermore, the mounting plate 14 is provided with an elongated hole 141 through which the saw blade 12 passes.

[0032] The elongated hole 141 is designed so that a portion of the saw blade 12 passes through the mounting plate 14 to cut the workpiece.

[0033] In use, the mounting plate 14 is partially attached to the object to be cut, and a portion of the saw blade 12 passes through the mounting plate 14 via the elongated hole 141 and acts on the object to be cut, thus cutting the object.

[0034] In this embodiment, the mounting plate 14 divides the cutting fixture into upper and lower parts. The upper part of the mounting plate 14 is the assembly area of ​​the cutting fixture, and the lower part of the mounting plate 14 is the cutting working area of ​​the saw blade 12.

[0035] Furthermore, a through hole 121 is provided at the center of the saw blade 12, and the connecting rod 11 passes through the through hole 121 and is detachably fixedly connected to the saw blade 12; the axis of the connecting rod 11 is collinear with the axis of the saw blade 12.

[0036] The saw blade 12 is detachably fixed to the connecting rod 11, making the saw blade 12 replaceable. On the one hand, this facilitates the maintenance and replacement of the saw blade 12 after damage. On the other hand, it allows for the replacement of the saw blade 12 with a suitable one for different application scenarios such as landscaping and grooving or different cutting intensities, thus expanding the scope of application.

[0037] Furthermore, such as Figure 3 As shown, a cutting saw blade 122 is mounted on the connecting rod 11.

[0038] The cutting saw blade 122 cuts high-level tree branches, providing convenience for greening maintenance and improving work efficiency.

[0039] Furthermore, such as Figure 5 As shown, one, two or more grooving saw blades 123 are provided on the connecting rod 11, and a grooving spacing is reserved between the two or more grooving saw blades 123.

[0042] The connecting rod fixing seat 13 includes two separable parts: an upper fixing seat 131 and a lower fixing seat 132. A receiving hole 133 for accommodating the fixing bearing 17 is formed between the upper fixing seat 131 and the lower fixing seat 132.

[0043] The diameter of the receiving hole 133 is smaller than the outer diameter of the outer ring of the bearing 17 to achieve an interference fit between the bearing 17 and the receiving hole 133; the connecting rod 11 passes through the inner ring of the bearing 17 and is fixedly connected to the inner ring of the bearing 17.

[0044] The bearing 17 is provided so that the saw blade 12 can be fixed on the mounting plate 14 and driven to rotate by the drive device 16.

[0045] Furthermore, such as Figure 1-2 As shown, it also includes a locking member 18, which locks and fixes the mounting plate 14, the upper fixing seat 131 and the lower fixing seat 132.

[0046] The locking element 18 serves two purposes: firstly, it locks the relative position of the mounting plate 14 and the connecting rod fixing seat; secondly, it connects the upper fixing seat 131 and the lower fixing seat 132 and locks the bearing 17 into the receiving hole 133 of the connecting rod fixing seat, thus fixing the relative position of the connecting rod fixing seat and the bearing 17.

[0047] In this embodiment, the locking member 18 includes a screw and a nut. The screw passes through the mounting plate 14, the lower fixing seat 132 and the upper fixing seat 131 in sequence and locks with the nut.

[0048] like Figure 3 As shown, in another preferred embodiment, locking nuts 19 are provided on both sides of the saw blade 12; the locking nuts 19 are threadedly engaged with the connecting rod 11 to fix the saw blade 12 between the two locking nuts 19.

[0049] The relative position of the saw blade 12 and the connecting rod 11 is fixed by the cooperation of the locking nut 19 and the connecting rod 11, ensuring stability during cutting.

[0050] Furthermore, a washer is provided between the locking nut 19 and the saw blade 12 to protect the saw blade 12 from damage and to provide shock absorption during the cutting process.

[0051] Furthermore, to ensure the stability of the bearing 17, locking nuts 19 are also provided on both sides of the bearing 17 to fix the relative position between the bearing 17 and the connecting rod 11.

[0052] Furthermore, the area of ​​the connecting rod 11 between the bearing 17 and the saw blade 12 can be defined by a shim to limit the distance between the bearing 17 and the saw blade 12.

[0053] like Figure 1-2 As shown, in another preferred embodiment, a protective cover 20 is also included, which covers the saw blade 12 and is fixedly connected to the connecting rod fixing seat 13.

[0054] The protective cover 20 is designed to prevent debris from flying during cutting and causing injury to the user.

[0055] like Figure 1-2 As shown, in another preferred embodiment, the mounting plate 14 and the telescopic rod 15 are connected by a connector 21, which is set at an angle to the mounting plate 14.

[0056] The connector 21 is set at an angle to the mounting plate 14, that is, the telescopic rod 15 is set at an angle to the mounting plate 14, which facilitates the application of force when the cutting fixture is used for high-altitude operations.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
