Technical Field

[0001] This application relates to a multi-functional utility knife, and more particularly to a utility knife with cutting, scraping, and shoveling functions. Background Technology

[0002] Ordinary utility knives can only cut, not scrape or shovel, making their function relatively limited. Improvements have been made to utility knives with cutting, scraping, and shoveling capabilities, but these typically switch between functions by rotating the blade, resulting in a very complex structure, numerous parts, and high cost. Therefore, it is necessary to improve utility knives to achieve multiple functions (cutting, scraping, shoveling, etc.) while controlling costs. Utility Model Content

[0003] The main objective of this invention is to provide a multi-functional utility knife with blades mounted at both ends of the front edge. With the blades mounted at the front, it functions as a regular utility knife; with the blades mounted at a different angle at the rear, it functions as a scraper or spatula. This multi-functional utility knife has a simple structure and can perform multiple functions including cutting, scraping, and shoveling.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0026] like Figure 1 and 2 As shown, a multi-functional utility knife 100 includes a housing 10, a blade 6, a knife holder 2 disposed at the front end of the housing 10, and a knife base 3 disposed at the rear end of the housing 10. The blade 6 can be selectively mounted on at least one of the knife holder 2 and the knife base 3. The front end and the rear end of the housing 10 define the front-back direction.

[0027] When the blade 6 is installed on the tool holder 2, it extends from the front end of the housing 10, and the cutting edge of the blade 6 is parallel to the front-rear direction of the housing 10. When the blade 6 is installed on the tool holder 3, it extends from the rear end of the housing 10, and the cutting edge of the blade 6 intersects with the front-rear direction of the housing 10.

[0028] The multi-functional utility knife 100 has two mounting positions for its blade 6, one at the front and one at the rear. Different positions correspond to different functions. Specifically, when the blade 6 is mounted at the front of the housing 10, it functions as a regular utility knife 100. When mounted at the rear of the housing 10 at a different angle, it functions as a scraper or spatula. Furthermore, this multi-functional utility knife 100 achieves multiple functions—cutting, scraping, and shoveling—with a simple structure and low manufacturing cost.

[0029] In this embodiment, the housing 10 is assembled from a left half-shell 11 and a right half-shell 12, and the front and rear ends of the housing 10 are respectively open. The blade 6 can be installed on the blade holder 2 and protrude from the opening at the front end of the housing 10, thus having a cutting function. The blade 6 can be installed on the blade holder 3 and protrude from the opening at the rear end of the housing 10, thus having a scraping or shoveling function.

[0030] Specifically, the blade 6 is mounted at the rear end of the housing 10 to achieve the scraping function. The specific installation structure is as follows.

[0031] Combination Figures 2-5 As shown, the blade holder 3 is fixedly mounted on the left half-shell 11 or the right half-shell 12. The blade 6 has at least one fixing groove 61, and the blade holder 3 has a boss 31 corresponding to each fixing groove 61. The shape of the fixing groove 61 is adapted to the shape of the boss 31 so that the fixing groove 61 of the blade 6 engages with the boss 31, thereby allowing the blade 6 to be installed on the blade holder 3. The blade 6 extends from the opening at the rear end of the housing 10, exposing its cutting edge, which intersects the front-rear direction of the housing 10. Preferably, the cutting edge of the blade 6 is perpendicular to the front-rear direction of the housing 10. That is, when the blade 6 is used as a shovel, its cutting edge angle can be adjusted to adapt to different scenarios. However, the best effect is achieved when the cutting edge is perpendicular to the front-rear direction. In this embodiment, the blade 6 has two fixing grooves 61, and the blade holder 3 is provided with two bosses 31 to secure the assembly of the blade 6 and the bosses 31.

[0032] Preferred, such as Figure 5As shown, a tool change button 41 is also provided at the rear end of the housing 10. An elastic sheet 32 ​​is installed on the tool holder 3. The elastic sheet 32 ​​has an elastic protrusion 321. The blade 6 has a mounting hole 62, and the elastic protrusion 321 passes through the mounting hole 62. The tool change button 41 passes through the left half-shell 11 or the right half-shell 12, and then passes through the mounting hole 62 of the blade 6 to abut against the elastic protrusion 321 of the elastic sheet 32.

[0033] When the operator presses the tool change button 41, the tool change button 41 acts on the elastic protrusion 321, causing the elastic protrusion 321 to press down and disengage from the mounting hole 62 of the blade 6. That is, the elastic protrusion 321 releases the restriction on the blade 6, and at this time the blade 6 can move in the front-back direction and be pulled out from the housing 10, thereby realizing the disassembly of the blade 6 at the rear end of the housing 10.

[0034] The elastic sheet 32 ​​also has a guide surface 321a. The guide surface 321a is used to guide the blade 6 into the boss 31. Specifically, the guide surface 321a faces the opening at the rear end of the housing 10. When the blade 6 needs to be installed from the rear end of the housing 10, the blade 6 moves along the guide surface 321a toward the interior of the housing 10, so that the fixing groove 61 of the blade 6 engages with the boss 31 of the blade holder 3, and when the elastic protrusion 321 encounters the mounting hole 62 of the blade 6, it extends into the mounting hole 62 to lock the blade 6, thereby realizing the installation of the blade 6 at the rear end of the housing 10.

[0035] The blade 6 is mounted on the front end of the housing 10 to achieve the cutting function. The specific mounting structure is as follows.

[0036] Combination Figure 2 , 3 As shown in Figure 6, a blade holder 2 is mounted on the left half-shell 11 or the right half-shell 12. The blade 6 is mounted on the blade holder 2 and extends out from the opening at the front end of the shell 10, with the cutting edge of the blade 6 parallel to the front-rear direction of the shell 10. The utility knife 100 also includes a telescopic mechanism connected to the blade holder 2. The telescopic mechanism is used to drive the blade holder 2 to reciprocate in the front-rear direction, causing the blade 6 to extend or retract from the opening at the front end of the shell, and to control the extension amount of the blade 6.

[0037] Specifically, a sliding groove 15 is formed on the top of the housing 10. The telescopic mechanism includes a push block 5. Figure 3 and 6As shown, the push block 5 includes, from top to bottom, an action part 51, a mounting part 52, and a mounting rod 53. The action part 51 protrudes from the top of the housing for the operator to push and pull. The width of the mounting part 52 is greater than the diameter of the mounting rod 53. The tool holder 2 has a connecting hole 21, and the mounting rod 53 of the push block 5 is inserted into the connecting hole 21 of the tool holder 2, connecting the push block 5 to the tool holder 2. Therefore, the push block 5 can drive the tool holder 2 to reciprocate along the sliding groove 15.

[0038] This telescopic mechanism also has a fixed-point function. Specifically, such as... Figure 3 As shown, the housing has multiple locking points 16 along the sliding groove 15. The distance between any two adjacent locking points 16 is equal. A spring 54 is sleeved on the mounting rod 53 of the push block 5, and the spring 54 is used for the reset of the push block 5. The spring 54 is restricted by the mounting part 52 and the tool holder 2. In its original state, the mounting part 52 of the push block 5 can abut against the locking points 16 to restrict the movement of the push block 5. When the operator presses the actuating part 51 of the push block 5, the push block 5 moves slightly downward, the spring 54 is compressed, the mounting part 52 of the push block 5 can disengage from the locking points 16, and the push block 5 is released from restriction, thus being able to move along the sliding groove 15. Therefore, the operator can push and pull the push block 5 while pressing it, causing the push block 5 to move along the sliding groove 15. When the push block 5 drives the tool holder 2, and the tool holder 2 moves the blade 6 to the appropriate position, the operator releases the actuating part 51. The push block 5 moves upward under the action of the spring 54, so that the mounting part 52 of the push block 5 abuts against the locking point 16 of the housing again, thereby locking the position of the push block 5.

[0039] like Figure 6 As shown, in order to limit the downward movement distance of the push block 5, the mounting part 52 of the push block 5 is provided with an inclined surface 52a, which cannot completely pass through the connecting hole 21 of the tool holder 2.

[0040] Another tool changing device 42 is provided at the front end of the housing. This tool changing device 42 is similar to the tool changing device at the rear end of the housing, so as to realize the function of quick replacement of the blade 6. Therefore, it will not be described in detail.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall still fall within the scope of the technical solution of this application.
