[0045] The connecting plate A101 has a connecting groove A109 at one end for connecting to an oscillating saw. Figure 1-Figure 5 As shown, the connection groove A109 is set in a circular shape, and the side away from the connection groove A109 is set in a square shape, and the square and the circular arc are smoothly transitioned into a whole, and the other end is stacked with a middle plate 102 and an upper panel 103 in sequence; the material of the connection plate A101 is 65Mn, 38-42HRC, flat, durable and non-deformed;

[0046] A snap-in slot A110 is provided in the middle plate 102, and the snap-in slot A110 is set in a parallelogram shape. The blade body 3 is plugged into the snap-in slot A110, and the area where the blade body 3 is inserted into the snap-in slot A110 is the insertion area, and the area outside the snap-in slot A110 is the cutting area. The area of ​​the insertion area is 2-2.5 times the area of ​​the cutting area. The force applied to the cutting area during the cutting process is transferred to other parts through the insertion area, so that the insertion area maintains 2-2.5 times the area of ​​the cutting area, so that the leaked cutting area can remain straight during cutting and is not easy to bend. The snap-in slot A110 set in the middle plate 102 is provided with openings on the upper and lower sides, and the upper panel 103 and the connecting plate A101 on the upper and lower sides respectively block the upper and lower openings, and together form a closed snap-in slot A110 for storing the blade body 3. It should be noted that a snap-in surface A111 is provided in the snap-in slot A110, and the blade body 3 has a mounting surface, and the snap-in surface A111 is in contact with the mounting surface;

[0047] The blade body 3 is inserted into the card slot A110, and its position needs to be fixed. Therefore, a push block seat 104 is installed on the side of the upper panel 103 away from the connecting plate A101, and a push block 105 is slidably installed in the push block seat 104. The push block 105 has at least two states, wherein the two states are a locked state and an open state. In the locked state, the position of the blade body 3 inserted into the card slot A110 is locked, and in the open state, the blade body 3 can move along the card slot A110.

[0048] Furthermore, the direction in which the push block 105 moves is the same as or opposite to the direction in which the blade body 3 moves along the connecting groove A109. The push block 105 is connected to a spring A107, which can provide elastic force to move the blade body 3 along the connecting groove A109.

[0050] The connecting plate A101, the middle plate 102, the upper panel 103, and the push block seat 104 are fixedly connected by bolts A108. It should be noted that there are five bolts A108. The middle plate 102 and the upper panel 103 are both configured as parallelograms with substantially the same shape as the connecting groove A109. Three of the five bolts A108 are respectively located at the three corners of the parallelogram. Figure 1 For example, the remaining two bolts are roughly located at the last corner of the parallelogram. In order to more stably fix the push block seat 104, two bolts A108 are respectively installed at the upper and lower ends of the right side of the push block seat 104;

[0051] A knife sheath 5 is installed on the blade body 3. The cavity in the knife sheath 5 is the same as the cutting area in the blade body 3. A through hole 501 is provided in the knife sheath 5. The setting of the through hole 501 can facilitate the status of the blade body 3. The knife sheath 5 covers the blade body 3. When the blade body 3 is not in use, its blade head is blocked to avoid cutting human limbs or other objects. Example

[0052] like Figure 6-Figure 9 As shown, an oscillating saw connector and a blade connected thereto include a connector body and a blade body 3. The connector body adopts a connector B2 (connector B is Figure 6-Figure 9 2), the connector body (i.e., connector B2) includes a connecting plate B201, a fixing seat 202, a button 203, a spring B204, a connecting groove B207, a snap-fit ​​groove B208, and a snap-fit ​​surface B209;

[0053] The connecting plate B201 has a connecting groove B207 at one end for connecting with the swing saw, and a fixing seat 202 is installed at the other end. It should be noted that a fixing groove hole is provided in the connecting plate B201, and the fixing groove hole cooperates with the boss in the fixing seat 202. There are multiple bosses, including round bosses and square bosses.

[0054] The fixing seat 202 is provided with a snap-in groove B208 for cooperating with the blade body 3. The portion of the blade body 3 inserted into the snap-in groove B208 is called the insertion area, and the remaining area is called the cutting area. The area of ​​the insertion area is 2-2.5 times the area of ​​the cutting area. The snap-in groove A110 and the snap-in groove B208 have the same function, which is to install the blade body 3. The area and shape of the inside are also the same. The snap-in groove B208 is provided with a snap-in surface B209, which is flush with the installation surface of the blade body 3. The fixing seat 202 is slidably connected with a button 203.

[0055] It should be noted that the square step inside the button 203 cooperates with the card slot in the blade body 3, and the button 203 can move in a direction perpendicular to the blade body 3. The button 203 has at least two states including a fixed state and a released state. In the fixed state, the position of the blade body 3 inserted into the card slot B208 is fixed and cannot be moved. In the released state, the blade body 3 and the card slot B208 can slide relative to each other.

[0056] Furthermore, the button 203 is connected to the spring B204, and a spring sheet 205 is provided at the position of the clamping groove B208 in the fixing seat 202. The spring sheet 205 is located on the side of the blade body 3 close to the fixing seat 202. The spring sheet 205 can provide an extrusion force to increase the radial force between the blade body 3 and the inner wall of the clamping groove B208, so as to better lock the position of the blade body 3 in the clamping groove B208;

[0057] Furthermore, the connecting plate B201 and the fixing seat 202 are fixedly connected by bolts B206. It should be noted that there are four bolts B206, and the fixing seat 202 is configured to be a parallelogram shape similar to the shape of the clamping groove B208. The four bolts B206 are respectively located at the four corners of the parallelogram.

[0058] It should be noted that a knife sheath 5 is installed on the blade body 3. The cavity in the knife sheath 5 is the same size as the cutting area in the blade body 3. A through hole 501 is provided in the knife sheath 5. The setting of the through hole 501 can facilitate checking the status of the blade body 3. The knife sheath 5 covers the blade body 3. When the blade body 3 is not in use, its blade head is blocked to avoid cutting human limbs or other objects. Example

[0059] like Figure 10-11 As shown, the blade body 3 mentioned in the first and second embodiments, the blade body 3 includes a blade A301, the blade A301 is set to an isosceles trapezoidal shape, and there are two card slots in the blade A301, namely a left card slot 401 and a right card slot 402, and two cutter heads A3011 are set at the two corners of the isosceles trapezoidal blade A301, and the two cutter heads A3011 can be used interchangeably (specifically, the blade A301 can be replaced and flipped, that is, any one of the two cutter heads A3011 can be facing outward, so its cutting area is not fixed, and can be selected at the two cutter heads A3011, and can be adjusted as needed), the two cutter heads A3011 can be used interchangeably, and during the exchange process, the position of the blade A301 needs to be flipped and replaced, and during the flipping and replacement process, the card connection position changes, so it is necessary to set a left card slot 401 and a right card slot 402, and the two card slots are used when the two cutter heads A3011 are fixed;

[0060] It should be noted that the first deflection angle A in the blade A301 is between 50° and 65°. The first deflection angle A of the blade A301 cooperates with the clamping surface A111 and the clamping surface B209. The angle is closely related to the size of the cutting area A. In practice, it is found that the first deflection angle A is between 50° and 65°. During the feeding process of the blade A301, the fingers pinch the cutting area A to push and pull the blade A301, which is more convenient to bear the force. The cutting force provided by the cutting area A during cutting is relatively stable.

[0061] Fig.11 It is a distribution diagram of the insertion area A and the cutting area A of the blade A301, wherein the insertion area A is a parallelogram shape having the same shape as the connecting groove A109 and the connecting groove B207. Example

[0062] like Figure 12-13 As shown, the blade body 3 mentioned in the first and second embodiments, the blade body 3 includes a blade B302, the blade B302 is set to an isosceles trapezoidal shape, and there are two card slots in the blade B302, namely a left card slot 401 and a right card slot 402, and two cutting heads B3021 are set at the two corners of the isosceles trapezoidal blade B302, and the cutting heads B3021 are set to a hook shape, and the two cutting heads B3021 can be used interchangeably (specifically, the blade B302 can be replaced and flipped, that is, the two cutting heads B3021 can be respectively facing outwards, and one of the cutting heads B3021 can be used as needed), and the two cutting heads B3021 can be used interchangeably. During the exchange process, the position of the blade B302 needs to be flipped and replaced. During the flipping and replacement process, the position of the card slot changes, so it is necessary to set a left card slot 401 and a right card slot 402, and the two card slots are used when the two cutting heads B3021 are fixed;

[0063] It should be noted that the first deflection angle B in the blade B302 is between 50° and 65°;

[0064] Fig.13 It is a distribution diagram of the insertion area B and the cutting area B of the blade B302, wherein the insertion area B is a parallelogram shape which is the same as the shape of the connecting groove A109 and the connecting groove B207.

[0065] Traditional blades such as Fig.14 As shown, it is directly connected to the oscillating saw, and a hole for connecting to the oscillating saw needs to be set on it. In order to facilitate the installation between it and the oscillating saw, its own length needs to be appropriately lengthened (a certain space is required to make the hole for connecting the oscillating saw). The corresponding production cost is relatively high. When damaged, the entire blade is scrapped, and the cost of replacing the blade is relatively high.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
