[0028] According to an embodiment of the utility model, a multi-angle cutting and planing tool head is provided.

[0029] Embodiment 1;

[0030] like Figure 1-5As shown, the multi-angle cutting planing head according to the embodiment of the utility model includes a planing head body 1, one side of the planing head body 1 is fixedly connected to a hinged rod 8, the hinged rod 8 is movably connected to a mounting rod 2 through an angle adjustment structure 7, one side of the mounting rod 2 is threadedly connected to a handle 4, and the outer side of the handle 4 is fixedly connected to an anti-slip layer 5.

[0031] The angle adjustment structure 7 includes a fixing plate 701, which is fixedly connected to one side of the two ends of the mounting rod 2. A clamping block 702 is snap-connected to one side of the fixing plate 701. A plurality of clamping grooves 704 matching the clamping block 702 are provided on the outer side of the hinged rod 8. The angle of the planing head body 1 can be flexibly adjusted through the angle adjustment structure 7 to increase the applicability during use. The mutual engagement between the clamping block 702 and the clamping groove 704 can better adjust the angle of the hinged rod 8 and the planing head body 1.

[0032] The upper and lower ends of one side of the clamping block 702 are fixedly connected to the limiting spring 703, and the limiting spring 703 and the fixing plate 701 are welded into an integrated structure. The elastic force of the limiting spring 703 can assist the clamping block 702 in resetting its position, so that the clamping block 702 can be more stably engaged with the clamping slot 704.

[0033] The cross section of the clamping block 702 is T-shaped, and one side of the clamping block 702 passes through the fixing plate 701 and extends to the inside of the hinge rod 8. The shape of the clamping block 702 facilitates pulling and prevents separation.

[0034] One side of the handle 4 is provided with a mounting groove 3 matching the mounting rod 2. The top of the handle 4 is connected with a disassembly structure 6, which can realize the installation and fixation between the mounting rod 2, the mounting groove 3 and the handle 4, thereby ensuring the stability of the whole during use.

[0035] The disassembly and assembly structure 6 includes a bolt 601, which is threadedly connected to the top of the handle 4, and a thread groove 602 matching the bolt 601 is provided at the top of the mounting rod 2. The mounting rod 2 and the handle 4 are secondarily fixed by the threaded connection between the bolt 601 and the thread groove 602.

[0036] A first anti-sliding block 603 is fixedly connected to both sides of the bottom end of the bolt 601, and a second anti-sliding block 604 matching the first anti-sliding block 603 is fixedly connected below the bolt 601 at the top end of the handle 4. The mutual cooperation between the first anti-sliding block 603 and the second anti-sliding block 604 can increase the friction between the handle 4 and the bolt 601, thereby increasing the applicability during use.

[0037] The second anti-slip block 604 and the first anti-slip block 603 are both semicircular in shape, and the first anti-slip block 603 and the second anti-slip block 604 are engaged with each other, which can increase the anti-slip performance of the bolt 601 during use and increase the stability during use.

[0038] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0039] In actual application, the installation and fixation between the mounting rod 2, the mounting groove 3 and the handle 4 can be achieved through the disassembly and assembly structure 6, ensuring the stability of the whole during use. By rotating the mounting rod 2, the mounting rod 2 and the mounting groove 3 are connected by a basic thread, and then by rotating the bolt 601, the bolt 601 and the threaded groove 602 are connected by a thread to perform a secondary fixation between the mounting rod 2 and the handle 4. The mutual cooperation of the first anti-sliding block 603 and the second anti-sliding block 604 can increase the friction between the handle 4 and the bolt 601, thereby increasing the applicability during use. The angle of the planing head body 1 can be flexibly adjusted through the angle adjustment structure 7, thereby increasing the applicability during use. The block 702 is pulled and separated from the slot 704, and then the planing head body 1 is rotated, so that the planing head body 1 drives the hinge rod 8 to rotate at both ends of the mounting rod 2, thereby achieving the angle adjustment of the planing head body 1. The pulling force applied to the block 702 is removed, so that the block 702 returns to its original position through the elastic force of the limit spring 703 and engages with the slot 704, thereby increasing the stability during use.

[0040] In summary, with the aid of the above-mentioned technical solution of the utility model, the installation and fixation between the mounting rod 2, the mounting groove 3 and the handle 4 can be realized through the disassembly and assembly structure 6, thereby ensuring the stability of the whole during use; and the angle adjustment structure 7 can realize flexible adjustment of the angle of the planer head body 1, thereby increasing the applicability during use.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
