Description

Technical Field

[0001] The utility model relates to the technical field of paving tools, and specifically relates to a manual cutting machine. Background Art

[0002] A manual cutting machine is a paving tool that can cut decorations such as tiles and glass. Generally, the cutting of the surface of an object is achieved by rolling a cutter wheel installed on the manual cutting machine. After the cutter wheel finishes cutting the surface of the object, the pressure foot installed on the manual cutting machine is used to press the two cut parts of the object to divide the cut object into two pieces.

[0003] In order not to affect the movement of the cutter wheel during cutting, the pressure foot is generally rotatably and movably connected to the manual cutting machine. When the cutter wheel cuts, the pressure foot is lifted, and after cutting is completed, the pressure foot is lowered to press the object. In the existing manual cutting machine, the pressure foot is generally rotatably and movably connected to the manual cutting machine through bolts and nuts, and the bolts and nuts need to be rotated correspondingly when the pressure foot is retracted and lowered, which is relatively troublesome to use. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a manual cutting machine that can make the retraction and lowering of the pressure foot more convenient and fast.

[0005] In order to solve the above technical problem, the technical solution provided by the utility model is as follows:

[0006] A manual cutting machine includes a base, a guide rail fixedly connected to the base, a cutting machine head slidably connected to the guide rail, a handle rotatably and movably connected to the cutting machine head, and a pressure foot rotatably and movably connected to the bottom of the handle. It is characterized in that it further includes:

[0007] A magnetic adsorption structure, which is located between the pressure foot and the handle, and the magnetic adsorption structure can make the pressure foot in an adsorbed state;

[0008] An adsorption release structure, which is used to release the adsorption cooperation between the magnetic adsorption structures, includes a pin shaft arranged on the handle and a torsion spring sleeved on the pin shaft.

[0036] As Figure 1 shown, the manual cutting machine of this embodiment is provided with a base 10, a guide rail 11 is fixedly connected to the base 10, a cutting head 12 is slidably connected to the guide rail 11, a handle 13 is rotatably connected to the cutting head 12, and a pressing foot 14 is rotatably connected to the bottom of the handle 13.

[0037] As Figure 1 and Figure 2 shown, four support plates 15 are provided on the base 10, and the base 10 and the support plates 15 are elastically connected. As Figure 7 shown, in this embodiment, a first compression spring 17 is provided between the base 10 and the support plates 15. When the ceramic tile is placed on the support plate 15, the first compression spring 17 can play a role in shock absorption and protection for the ceramic tile, preventing the ceramic tile from cracking when placed.

[0038] As Figure 1 and Figure 2 shown, two support feet 16 are provided on the side of the base 10, and the support feet 16 and the base 10 are elastically connected. As Figure 7As shown, in this embodiment, a first fastener 18 is provided on the base, and a second fastener 19 is provided on the support leg 16. The first fastener 18 and the second fastener 19 are threadedly connected. A second compression spring 171 is provided between the first fastener 18 and the second fastener 19. The support leg 16 can increase the contact area between the base 10 and the ground, so that the base 10 is placed more stably on the ground. The threaded connection between the first fastener 18 and the second fastener 19 can facilitate the adjustment of the height of the support leg 16, so that the base 10 can adapt to uneven ground. The second compression spring 171 can play a role in shock absorption and buffering, and better protect the base 10 and the tiles placed thereon.

[0039] As Figure 3 shown, a magnetic adsorption structure 20 and an adsorption release structure 30 for releasing the adsorption cooperation between the magnetic adsorption structures 20 are provided between the pressing foot 14 and the handle 13. A limiting structure 40 for fixing the handle 13 is further provided on the handle 13, and the limiting structure 40 is provided on the side of the guide rail 11.

[0040] As Figure 5 shown, the magnetic adsorption structure 20 includes a magnet 21 and an adsorption portion 22 that adsorbs and cooperates with the magnet 21, and the magnetic adsorption structure 20 keeps the pressing foot 14 in an adsorbed state. In this embodiment, the magnet 21 is provided on the side of the pressing foot 14, and the adsorption portion 22 is provided at the bottom of the handle 13. Of course, setting the magnet 21 at the bottom of the handle 13 and the adsorption portion 22 on the side of the pressing foot 14 can also achieve the same technical effect. In this embodiment, the adsorption portion 22 is an iron screw, which can save costs. Of course, it can also be replaced with other metals or magnetic materials that can be adsorbed by the magnet 21.

[0041] As Figure 6 shown, the adsorption release structure 30 includes a pin shaft 31 provided on the handle 13 and a torsion spring 32 sleeved on the pin shaft 31, and a limiting portion 131 is provided on the handle 13.

[0042] As Figure 4 shown, the torsion spring 32 includes a spiral body 321, a first torsion arm 322, and a second torsion arm 323, and a bent convex portion 324 is provided on the second torsion arm 323.

[0043] As Figure 6 shown, the pressing foot 14 is in an adsorbed state, the spiral body 321 is sleeved on the pin shaft 31, the first torsion arm 322 is fixedly adapted to the limiting portion 131, the second torsion arm 323 is located between the bottom of the guide rail 11 and the pressing foot 14 in the adsorbed state, and the bent convex portion 324 is located on the side of the torsion spring 32 close to the guide rail 11.

[0044] When the handle 13 is rotated upward, the handle 13 will drive the torsion spring 32 connected to the handle 13 to move upward accordingly until the second torsion arm 323 of the torsion spring 32 touches the bottom of the guide rail 11. The bent convex part 324 on the torsion spring 32 will first contact the bottom of the guide rail 11. Since the first torsion arm 322 is restricted by the limiting part 131, the second torsion arm 323 will rotate downward to contact the pressure foot 14, driving the pressure foot 14 to release the adsorption fit between the magnetic adsorption structures 20, so that the pressure foot 14 is lowered.

[0045] As Figure 8 and Figure 9 shown, a first through hole 132 is provided on the handle 13, and first clamping grooves 133 and second clamping grooves 134 with different directions and depths are provided on the inner wall of the handle 13. In this embodiment, the depth of the first clamping groove 133 is greater than the depth of the second clamping groove 134, and the directions of the first clamping groove 133 and the second clamping groove 134 are perpendicular to each other.

[0046] As Figure 10 shown, the limiting structure 40 includes a first positioning pin 41, and the first positioning pin 41 is adapted to the first through hole 132. A handheld part 43 is fixedly provided at one end of the first positioning pin 41 away from the guide rail 11, and a second positioning pin 42 is fixedly connected to one end of the first positioning pin 41 close to the guide rail 11, and the second positioning pin 42 penetrates the radial direction of the first positioning pin 41. An elastic member 44 is provided between the handle 13 and the handheld part 43. In this embodiment, the elastic member 44 is preferably a compression spring sleeved on the first positioning pin 41, which can drive the first positioning pin 41 to move away from the guide rail 11, so that the second positioning pin 42 can be smoothly engaged with the first clamping groove 133 or the second clamping groove 134.

[0047] In this embodiment, a second through hole 431 is provided in the radial direction of the handheld part 43, and a third positioning pin 45 is fixedly connected in the radial direction through one end of the first positioning pin 41 close to the handheld part 43, and the second through hole 431 is adapted to the third positioning pin 45. Of course, the handheld part 43 and the first positioning pin 41 can also adopt other fixed connection methods, such as bonding with glue, interference fit clamping, etc.

[0048] In order to facilitate the cutting function of the manual cutting machine in this embodiment, the handle 13 is rotatably and movably connected to the cutting head 12 of the manual cutting machine. When the handle 13 is not in use, it will have a tendency to lift upward under the action of the internal structure, but the handle 13 will still be in an active state and will swing up and down during transportation, which has the risk of damaging parts. The limiting structure 40 can cooperate with the guide rail 11 to fix the handle 13.

[0049] As Figure 11As shown, when the handle 13 is in normal use, the second positioning pin 42 is adapted to the first clamping groove 133 with a greater depth, and the left end of the second positioning pin 42 does not contact the guide rail 11.

[0050] As Figure 12 shown, when it is necessary to fix the handle 13, first push the handheld part 43 in the direction close to the guide rail 11, and then rotate the handheld part 43 until the direction of the second positioning pin 42 is the same as that of the second clamping groove 134, and the second positioning pin 42 is snapped into the second clamping groove 134. Since the depth of the first clamping groove 133 is greater than that of the second clamping groove 134, after the second positioning pin 42 is snapped into the second clamping groove 134, the first positioning pin 41 moves a certain distance in the direction close to the guide rail 13, and the left end of the first positioning pin 41 abuts against the lower part of the guide rail 11, restricting the upward lifting trend of the handle 13, thereby fixing the handle 13.

[0051] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
