[0033] To fully understand the purpose, features, and effects of this utility model, the following specific embodiments, in conjunction with the accompanying drawings, will provide a detailed description of this utility model:

[0034] Please see Figures 1 to 6 As shown in the figure, this utility model is a locking structure for a chain knife sheath, which includes a chain module 1, at least one connecting seat 2, at least one knife sheath body 3 and a locking unit 4.

[0035] The connector 2 is located on the chain module 1.

[0036] The sheath body 3 is removably attached to the connecting seat 2, and a pair of fasteners 31 are provided at the bottom of the sheath body 3.

[0037] The locking unit 4 is located on the connecting seat 2, and the locking unit 4 locks or unlocks with the fastener 31 of the blade sheath body 3.

[0038] Based on the above embodiments, when in use, the locking unit 4 can be used to lock or unlock the blade sheath body 3, so as to facilitate the replacement of the appropriate blade sheath body 3, thereby achieving the effect of simple structure and easy replacement.

[0039] In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that the fastener 31 is provided with a fixing part 311 and at least two snap-fit ​​parts 312. The fixing part 311 is laterally connected to the bottom of the blade sheath body 3, and each snap-fit ​​part 312 is longitudinally provided at both ends of the fixing part 311. The fixing part 311 is laterally connected to the bottom of the blade sheath body 3 by at least two fixing elements 313, and each snap-fit ​​part 312 is provided with a snap-fit ​​groove 314. Each snap-fit ​​part 312 is locked or unlocked with the locking unit 4 by the snap-fit ​​groove 314.

[0040] Based on the above embodiments, when in use, the locking unit 4 can be locked with the snap-fit ​​grooves 314 of the snap-fit ​​parts 312 on both sides of the fastener 31, so that the blade holder body 3 can be stably set on the connecting seat 2 by the cooperation of the fastener 31 and the locking unit 4 to set the relevant tools, and perform the required cutting action by the drive of the chain module 1.

[0041] When it is necessary to replace the blade sheath body 3, the locking unit 4 can be aligned with the snap-fit ​​groove 314 of the snap-fit ​​part 312 on both sides of the pair of fasteners 31 to unlock it, and the blade sheath body 3 can be removed after unlocking. In this way, the locking unit 4 can be used to lock or unlock the blade sheath body 3 to facilitate the replacement of the appropriate blade sheath body 3, thereby achieving the effect of simple structure and easy replacement.

[0042] In addition to the above embodiments, in one embodiment of this utility model, the difference from the above embodiments is that the locking unit 4 includes a push rod 41, at least two fastening parts 42, at least two unlocking parts 43, and an elastic element 44. The push rod 41 is movably disposed on the connecting seat 2, and one end of the push rod 41 extends out of the connecting seat 2. Each fastening part 42 and each unlocking part 43 is disposed on the push rod 41, and each fastening part 42 is located on one side of each unlocking part 43. An elastic element 44 is sleeved on the push rod 41. One end of the elastic element 44 abuts against the connecting seat 2, and the other end of the elastic element 44 abuts against one of the fastening parts 42. The elastic element 44 abuts against one of the fastening parts 44, causing one end of the push rod 41 to extend out of the connecting seat 2 in a normal state, and causing each of the fastening parts 42 to lock with the pair of fasteners 31. The push rod 41 moves into the connecting seat 2, causing each of the unlocking parts 43 to unlock the pair of fasteners 31.

[0043] Based on the above embodiments, when in use, the elastic force of the elastic element 44 can cause the elastic element 44 to abut against one of the fastening parts 44, causing one end of the push rod 41 to extend out of the connecting seat 2 in a normal state. At this time, each fastening part 42 is locked with the locking groove 314 of each of the latching parts 312 provided on both sides of the fastener 31, so that the blade sheath body 3 can be stably set on the connecting seat 2 by the cooperation of the fastener 31 and the locking unit 4 to set the relevant tools, and perform the required cutting action by the drive of the chain module 1.

[0044] When it is necessary to replace the blade sheath body 3, the push rod 41 can be pushed directly by manual force to move the push rod 41 into the connecting seat 2 and compress the elastic element 44, so that each of the unlocking parts 43 corresponds to the snap-fit ​​groove 314 of each of the snap-fit ​​parts 312 provided on both sides of the fastener 31 to unlock, and after unlocking, the blade sheath body 3 can be removed; in this way, the locking unit 4 can be used to lock or unlock the blade sheath body 3 to facilitate the replacement of the appropriate blade sheath body 3, thereby achieving the effect of simple structure and easy replacement.
