When locked, locking rod first protrusion 201 is locked in tool holder first slot 301, locking rod second protrusion 202 is locked in tool holder second slot 302, and locking rod third protrusion 203 is locked in tool holder third slot 304. Tool holder protrusion 303 is fixedly set between tool holder first slot 301 and tool holder second slot 302. When locked, tool holder protrusion 303 is locked into the opening side of first slot 204.

[0040] In order to move the locking lever 20 and limit the locking lever 20 when locking and unlocking, the handle 1 has a sliding groove 102; the two ends of the locking lever 25 are fixedly provided with fixing ears 251, and the fixing ears 251 have holes. The first bolt 24 located on the same side passes through the fixing ear 251 and the sliding groove 102 and is rotatably installed in the first locking hole 206. The first bolt 24 is threadedly engaged with the first locking hole 206, and the first bolt 24 is rotatably engaged with the fixing ear 251 and the sliding groove 102. The tool holder 1 has a first locking groove 100 and a second unlocking groove 101, the diameters of which are slightly smaller than the outer diameter of the locking lever 25. The tool holder 1 also has a third cutting groove 106, located between the first locking groove 100 and the second unlocking groove 101. Both the tool holder 1 and the tool post 3 have first fixing threaded holes 104. The tool holder 1 also has a second fixing threaded hole 105, located above the first fixing threaded hole 104. One end of a fixing bolt 4 passes through the first fixing threaded hole 104 on the tool holder 1 and is rotatably installed in the first fixing threaded hole 104 on the tool holder 3. The first fixing bolt 4 is threadedly engaged with the first fixing threaded hole 104 on the tool holder 1 and is rotatably engaged with the first fixing threaded hole 104 on the tool holder 3. One end of a second fixing bolt 5 passes through the second fixing threaded hole 105 on the tool holder 1 and is rotatably installed in the first slot 204. The second fixing bolt 5 is threadedly engaged with the second fixing threaded hole 105.

[0041] The handle portion of this product consists of a pair of handles 1. A tool holder 3 is rotatably mounted on one end of the handle 1. The tool holder 3 is used to fix and mount the blade. A locking structure 2 is provided between the two handles 1. The locking structure 2 is used to lock and unlock the tool holder 3.

[0042] When it is necessary to store the blade, rotate one end of the first slot 301 and the second slot 302 on the blade holder 3 near the first and second protrusions 201 and 202 on the locking rod 20. Simultaneously, push the locking rod 20, causing the first protrusion 201 to engage with the first slot 301, the second protrusion 202 to engage with the second slot 302, and the third protrusion 203 to engage with the third slot 304. At the same time, the protrusion 303 will engage with the first... Within the slot 204, the locking rod 20 limits the tool holder 3, preventing it from rotating further. Rotating the locking rod 25 engages it in the first locking groove 100. The diameter of the first locking groove 100 is slightly smaller than that of the locking rod 25. When the locking rod 25 is inserted into the first locking groove 100, it presses against the inner wall of the first locking groove 100, causing one end of the first locking groove 100 to expand toward the third cutting groove 106. This characteristic is used to lock the locking rod 25 in place, thus completing the locking process.

[0043] When it is necessary to unlock the tool, pull the locking lever 25 out of the first locking groove 100 and move it towards the second unlocking groove 101. When the second groove 205 moves, it will cause the locking lever 20 to slide towards the second unlocking groove 101. When the locking lever 20 moves, the first protrusion 201 and the second protrusion 202 of the locking lever separate from the first groove 301 and the second groove 302 of the tool holder, and the third protrusion 203 of the locking lever separates from the third groove 304 of the tool holder. At this time, the tool holder 3 loses the limitation of the locking structure 2 and can be unlocked. When the lever 25 is pulled, the locking lever 20 moves and compresses the spring 23 through the second limiting post 22. At this time, the lever 25 is locked into the second unlocking groove 101. Under the elastic force of the spring 23, the spring 23 will use its elastic restoring force to resist the locking lever 20 and apply elastic force to the side of the tool holder 3. The lever 25 is limited in the second unlocking groove 101. Thus, the lever 25 and the second unlocking groove 101 work together to limit the locking lever 20, which can ensure that the lever 25 will not shake and affect the operation during use.

[0044] When the locking structure 2 of this device wears out after long-term use, simply loosen the first fixing bolt 4, the second fixing bolt 5, and the first bolt 24. First, remove the first bolt 24, and then remove the knife handle 1 on one side. At this time, a new locking rod 20 can be replaced. Since the elastic component of this device is located in the second slot 205, the second slot 205 will not pop out when the knife handle 1 is removed. Therefore, unlike traditional knives, the elastic component will not pop out and cause other components to loosen. This makes this device easy to disassemble and maintain. After the replacement is completed, reset the knife handle 1 and reinstall the locking rod 25. Then, tighten all the bolts to complete the replacement easily.

[0045] The attached diagram only shows the structure of the tool holder, tool post, and locking mechanism. A corresponding filling structure should also be provided at the end of the two tool holders away from the tool post to fill the gap between the two tool holders and make them a complete whole. The shape of the filling structure can be set freely, as long as it does not interfere with the movement of the locking mechanism.

[0046] The working principle is as follows: When it is necessary to store the blade, rotate one end of the first slot 301 and the second slot 302 on the blade holder 3 near the first protrusion 201 and the second protrusion 202 on the locking rod 20. At the same time, push the locking rod 20 so that the first protrusion 201 on the locking rod 20 engages in the first slot 301 of the blade holder, the second protrusion 202 engages in the second slot 302 of the blade holder, and the third protrusion 203 engages in the third slot 304 of the blade holder. Simultaneously, the blade holder protrusion 303 will... When the lever 20 is inserted into the first slot 204, it limits the movement of the tool holder 3, preventing it from rotating further. Rotating the lever 25, the lever 25 is inserted into the first locking slot 100. The diameter of the first locking slot 100 is slightly smaller than that of the lever 25. When the lever 25 is inserted into the first locking slot 100, it will press against the inner wall of the first locking slot 100, causing one end of the first locking slot 100 to expand toward the third cutting slot 106. This characteristic is used to lock the lever 25 in place, thus completing the locking process.

[0047] When it is necessary to unlock the tool, pull the locking lever 25 out of the first locking groove 100 and move it towards the second unlocking groove 101. When the second groove 205 moves, it will cause the locking lever 20 to slide towards the second unlocking groove 101. When the locking lever 20 moves, the first protrusion 201 and the second protrusion 202 of the locking lever separate from the first groove 301 and the second groove 302 of the tool holder, and the third protrusion 203 of the locking lever separates from the third groove 304 of the tool holder. At this time, the tool holder 3 loses the limitation of the locking structure 2 and can be unlocked. When the lever 25 is pulled, the locking lever 20 moves and compresses the spring 23 through the second limiting post 22. At this time, the lever 25 is locked into the second unlocking groove 101. Under the elastic force of the spring 23, the spring 23 will use its elastic restoring force to resist the locking lever 20 and apply elastic force to the side of the tool holder 3. The lever 25 is limited in the second unlocking groove 101. Thus, the lever 25 and the second unlocking groove 101 work together to limit the locking lever 20, which can ensure that the lever 25 will not shake and affect the operation during use.

[0048] When the locking structure 2 of this device wears out after long-term use, simply loosen the first fixing bolt 4, the second fixing bolt 5, and the first bolt 24. First, remove the first bolt 24, and then remove the knife handle 1 on one side. At this time, a new locking rod 20 can be replaced. Since the elastic component of this device is located in the second slot 205, the second slot 205 will not pop out when the knife handle 1 is removed. Therefore, unlike traditional knives, the elastic component will not pop out and cause other components to loosen. This makes this device easy to disassemble and maintain. After the replacement is completed, reset the knife handle 1 and reinstall the locking rod 25. Then, tighten all the bolts to complete the replacement easily.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
