[0024] Reference Figure 1-6 , is an embodiment of the present invention, which provides a tool with a replaceable blade, mainly comprising:

[0025] The blade body 100, such as Figure 2 A locking groove 101 is provided at the bottom of the blade body 100 , and a first slot 102 and a second slot 103 are provided on one side of the blade body 100 .

[0026] Blade 200, such as Figure 2 The upper part of the blade 200 is adapted to be plugged into the engaging slot 101 , and the left and right ends of the blade 200 are provided with third slots 201 that are interconnected. The second slot 103 is connected to the engaging slot 101 and is correspondingly arranged with the third slot 201 .

[0027] A first fixing assembly 300 is provided at one end of the blade body 100 and is connected to the blade body 100 and the blade 200;

[0028] The first fixing component 300 includes a vertical rod 301 that is movably fitted with one end of the blade body 100. The vertical rod 301 is fixedly connected to the side of the blade body 100 with a first limiting rod 302 and a second limiting rod 303. The first limiting rod 302 and the second limiting rod 303 are arranged correspondingly up and down. The first limiting rod 302 is adapted to be plugged into the first slot 102, and the second limiting rod 303 is adapted to be plugged into the second slot 103 and the third slot 201. Through the plugging action of the first limiting rod 302 and the first slot 102 and the plugging action of the second limiting rod 303 and the second slot 103 and the third slot 201, the blade 200 and the blade body 100 can be preliminarily connected together.

[0029] The connecting frame 400 includes a connecting plate 401 located above the cutter body 100 and a pair of support rods 402 fixedly connected to both sides of the connecting plate 401. The lower portions of the pair of support rods 402 are fixedly connected to the upper portions of the two ends of the cutter body 100. The connection frame 400 facilitates the connection of the cutter to the machine.

[0030] The second fixing assembly 500 is located between the connecting plate 401 and the blade body 100 , and is connected to the connecting plate 401 , the blade body 100 , the first fixing assembly 300 and the blade 200 .

[0031] Specifically, protrusions 304 are fixedly connected to the front and rear sides of the vertical rod 301, and the protrusions 304 are arranged to protrude from the blade body 100 on the side away from the vertical rod 301. The advantage of this arrangement is that the protrusions 304 can easily drive the vertical rod 301, the first limiting rod 302, and the second limiting rod 303 to retreat, thereby facilitating the release of the blade 200.

[0032] Specifically, the second fixing assembly 500 includes a pair of electric telescopic rods 501 fixedly connected to the bottom of the connecting plate 401, and the bottom movable ends of the pair of electric telescopic rods 501 are fixedly connected to the same locking sleeve 502, and the locking sleeve 502 is nested in the top of the blade 100. The inner top wall of the locking sleeve 502 is fixedly connected to the third limiting rod 503, and the third limiting rod 503 is connected to the top of the blade 200, the first limiting rod 302, and the second limiting rod 303.

[0033] Furthermore, a fourth slot 104 connected to the locking slot 101 is provided on the top of the blade body 100, a fifth slot 202 is provided on the top of the blade 200 corresponding to the fourth slot 104, a sixth slot 305 is provided on the upper and lower sides of the first limiting rod 302 and the second limiting rod 303 corresponding to the fourth slot 104, and the third limiting rod 503 is adapted to be plugged into the fourth slot 104, the fifth slot 202, and the sixth slot 305 for fixing the first fixing component 300, thereby improving the stability of the blade 200.

[0034] In summary, when the blade 200 needs to be replaced, the electric telescopic rod 501 is started, and the movable end of the electric telescopic rod 501 drives the third limit rod 503 to move upward, so that the third limit rod 503 is separated from the blade 200, the second limit rod 303, and the first limit rod 302. After separation, the vertical rod 301, the first limit rod 302, and the second limit rod 303 are pulled back through the protrusion 304, so that the first limit rod 302, the second limit rod 303 are separated from the third slot 201 and the first slot 102, thereby releasing the fixation of the blade 200, and then the blade 200 is pulled out of the engaging slot 101 to complete the disassembly. The operation is simple and easy to disassemble and assemble, so that it is convenient to replace the worn or damaged blade 200 in the later stage without replacing the entire tool, which is not easy to cause waste of resources.

[0035] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
