The tenon structure 320 and the lower fixing plate 330 establish the connection relationship between the shank tail 100 and the interface body at both sides of the shank tail 100, which can increase the degree of firmness.

A spade handle connecting channel 410 is formed in the interface body, and the connecting channel 410 is arranged along the axial direction of the interface body. The spade handle connecting channel 410 forms a spade handle connecting port 480 on a side of the interface body facing away from the handle connecting port 310, and the spade handle connecting port 480 forms an opening for inserting the spade handle into the spade handle connecting channel 410. A fixing structure is arranged in the shovel handle connecting channel 410 and used for enabling a shovel handle to be inserted into the connecting channel 410 and then fixedly connected with the interface body.

In the embodiment of the invention, one end of the interface body is connected with the handle tail part 100 through the tenon structure 320 and the lower fixing plate 330, and the other end is fixedly inserted into the shovel handle, so that the tactical knife and the shovel handle are connected into a whole. The structure of the prior tactical knife and spade handle is not required to be changed, the applicability is strong, and the disassembly and the assembly are convenient.

Referring to fig. 1, 4 and 6, in one embodiment of the present invention, the fixing structure includes a limiting spacer 420 and a rotation limiting assembly, the limiting spacer 420 is configured to limit the axial movement of the shovel shaft after the shovel shaft is inserted into the connecting channel 410 and axially rotated, so as to prevent the shovel shaft from being separated from the interface body. Rotatory spacing subassembly is used for carrying out axial rotation spacing back to the spade at spacing baffle 420 to the spade carrying out axial displacement spacing, avoids the spade to lose spacing baffle 420's constraint behind the reverse rotation, breaks away from the interface body.

It can be appreciated that when the shovel handle is inserted into the shovel handle connecting channel 410 from the shovel handle connecting port 480 and rotated in one direction, the handle end tenon 210 of the shovel handle is rotated to the side where the limit spacer 420 deviates from the shovel handle connecting port 480, the limit spacer 420 axially limits the shovel handle, so that the shovel handle cannot slide out of the connecting channel 410. At this point, the rotation limiting assembly limits the axial rotation of the shovel handle to prevent the handle-end tenon 210 from moving away from the side of the shovel handle connector 480 by the limiting partition 420. When the spade handle is required to be separated from the interface body, the limitation of the rotary limiting component on the spade handle is required to be removed, and the spade handle can be pulled out from the spade handle connecting channel 410 only after the rotary spade handle enables the handle-end tenon 210 to be separated from the limiting partition plate 420 and deviate from one side of the spade handle connecting port 480.

In one embodiment of the present invention, the rotation limiting assembly includes an interface striking pin 430, a striking pin plug 440, and a resilient return member 450.
