DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to facilitate understanding of the technical solution of the present utility model, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment 1

[0024] As Figure 1As shown in the figure, a detachable tool knife includes a knife body 1 made of insulating material and a modular blade 2 detachably arranged on the knife body 1. The knife body 1 made of insulating material is provided at one end of the modular blade 2, which improves the safety of use. Specifically, only the end of the modular blade 2 is located on the handle of the knife body 1, so that there is a certain distance between the modular blade 2 and the hand, ensuring safety. Among them, the knife body 1 can be made of rubber material.

[0025] As Figures 2 - 3 shown in the figure, the knife body 1 includes a mounting base 11 and mounting side plates 12 located on the mounting base 11. The mounting base 11 is located at the end of the handle. A first mounting groove 111 is provided on the mounting base 11, and a second mounting groove 121 is provided on the side of the mounting side plate 12. The lower part of the modular blade 2 is located in the first mounting groove 111, and the side part of the modular blade 2 is located in the second mounting groove 121. A through pin hole 112 is provided on the mounting base 11, and a through hole for mounting the positioning pin 3 is provided at the corresponding position on the modular blade 2. The modular blade 2 is positioned by the positioning pin 3 passing through the pin hole 112 and the through hole.

[0026] As Figures 4 - 5 shown in the figure, the side of the mounting side plate 12 is recessed inward to form the second mounting groove 121. The two sides of the second mounting groove 121 are respectively a first side wall 122 and a second side wall 123. The first side wall 122 and the second side wall 123 are inclined towards the second mounting groove 121, that is, the first side wall 122 and the second side wall 123 are inclined and closely attached to the upper and lower surfaces of one side of the modular blade 2, and the modular blade 2 is prevented from coming out by friction.

[0027] In order to further prevent the modular blade 2 from detaching from the mounting side plate 12, two positioning protrusions 124 are provided in the second mounting groove 121, and positioning grooves 21 are provided at the corresponding positions on the modular blade 2.

[0028] As a preferred method, one positioning protrusion 124 is provided on each of the first side wall 122 and the second side wall 123, and the two positioning protrusions 124 are arranged in a staggered manner to prevent the modular blade 2 from deviating towards a certain side and coming out of the second mounting groove 121 during use.

[0029] Embodiment 2

[0030] As Figures 6 - 7 shown in the figure, the difference between Embodiment 2 and Embodiment 1 is that the modular blade 2 includes a first knife part 22 and a second knife part 23. The first knife part 22 and the second knife part 23 are vertically arranged. The first knife part 22 is located in the first mounting groove 111, and the second knife part 23 is located in the second mounting groove 121, that is, the shape of the modular blade 2 is approximately an L-shaped structure, and a vertical cutting edge can be cut on the surface of a square or approximately square object.

[0031] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model shall be subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present utility model shall also be regarded as within the protection scope of the present utility model.
