Description

Technical Field

[0001] The present invention mainly discloses a folding tool, particularly a folding tool with a locking mechanism. Prior Technology

[0002] Please refer to Chinese Patent No. M537006, "A Positioning Folding Tool," which is a folding tool comprising a shell, a support plate, a plurality of tool parts, a fixing part, and a positioning unit. The support plate is disposed inside the shell. Each tool part includes a positioning member with a plurality of grooves and a tool fixed to the positioning member. The fixing part includes a fixing member and a locking member. The positioning unit includes an elastic member and a positioning piece. A first end of the positioning piece is pushed by the elastic member, causing a second end of the positioning piece to present a first position. The first position is where the tool and the support plate form a first angle and are fixed to each other. Pressing the first end of the positioning piece compresses the elastic member, causing the second end of the positioning piece to present a second position. The second position is where the tool and the support plate move within a second angle range.

[0003] However, the tool part and the positioning plate of the above-mentioned folding tool are located on opposite sides of the tool. If the user presses the positioning plate first, the tool needs to be flipped over to see the tool part and rotate it. The same applies if the user grabs the tool first and then presses the positioning plate. Not only is it not easy to operate, but the length of the tool part cannot be too long so as not to block the positioning plate.

[0004] In view of the shortcomings of the above-mentioned conventional structures, the inventors have designed a folding tool with a locking mechanism, which can overcome all the disadvantages of the above-mentioned conventional structures. Summary of the Invention

[0005] The main objective of this invention, a folding tool with a locking mechanism, is to provide a folding tool comprising a body, a tool head assembly, and a positioning mechanism. The tool head assembly includes at least one first tool head, one end of which is provided with a first pivot portion. The first pivot portion is rotatably pivotally mounted to the body about a virtual first axis. At least one first locking portion is provided on the outer periphery of the first tool head at the first pivot portion. The positioning mechanism includes a first fastener and a first pressing button. The first fastener is movably mounted to the body and is provided with a first locking mechanism. The first button is movably connected to the body along the first axis between a first locked position and a first released position. When the first button is in the first locked position, it does not push the first fastener to move, so that the first buckle engages with the first latch and restricts the rotation of the first tool head relative to the body. When the first button is in the first released position, it pushes the first fastener to move, so that the first buckle disengages from the first latch and releases the restriction on the rotation of the first tool head relative to the body. The folding tool, through the above structure, is convenient for users to operate and provides a more efficient space configuration.

[0006] The first fastener is pivotally mounted on the body, and the pivot axis of the first fastener is parallel to the first axis.

[0007] The outer periphery of the first fastener is provided with a first protrusion at one end along the first axis. The first button is provided with a first guide portion. The first guide portion keeps in contact with the first protrusion. When the first button moves between the first locking position and the first releasing position, the first protrusion slides on the surface of the first guide portion.

[0008] The body includes a central seat with an integral structure. The central seat has a first pivot hole on each of its two opposite sides along the first axis. The positioning mechanism includes a first pin with its two ends inserted into the two first pivot holes. The first fastener is disposed in the central seat and can be rotated around the first pin.

[0009] The main body includes a first side cover and a second side cover. The first side cover and the second side cover are respectively connected to the middle seat on opposite sides along the first axis. The first side cover is provided with a first sliding groove on the side adjacent to the second side cover, and the second side cover is provided with a second sliding groove on the side adjacent to the first side cover.

The first flange slides in the first sliding groove, and the second flange slides in the second sliding groove.

[0010] The positioning mechanism includes a first elastic member with a first winding portion between its two ends. The first winding portion is wound at least once and sleeved on the first pin. One end of the first elastic member is inserted into the middle seat and the other end abuts against the side of the first fastener opposite to the first pivot portion. When the first button is in the first release position, the first fastener pushes the first elastic member to twist and deform. The first elastic member can provide a thrust to push the first fastener and push the first button to move to the first locking position through the first fastener.

[0011] The body includes a first pivot and two first locking members. The first pivot is inserted into the middle seat along the first axis. The two first locking members pass through the first side cover and the second side cover respectively from the side opposite to the middle seat of the first side cover and the side opposite to the middle seat of the second side cover and are connected to the first pivot by screw locking. The first pivot part is sleeved on the first pivot.

[0012] The middle seat has a non-circular first limiting hole on one side adjacent to the first side cover. The first pivot has a first limiting part with a shape corresponding to the first limiting hole on one end adjacent to the first side cover along the radial outer periphery of the first pivot. The first limiting part is inserted into the first limiting hole, so that the first pivot cannot rotate relative to the middle seat.

[0013] The tool head assembly includes at least one second tool head. One end of each second tool head has a second pivot portion, which is pivotally mounted to the body about a virtual second axis.

The second button is movably connected to the body between a second locked position and a second released position along the second axis. In the second locked position, the second button does not push the second fastener to move, allowing the second locking portion to engage with the second tool head. The second locking part restricts the rotation of the second tool head relative to the body. When the second button is in the second release position, the second button pushes the second fastener to move, causing the second fastener to disengage from the second locking part and releasing the restriction on the rotation of the second tool head relative to the body. The outer periphery of the second fastener has a second protrusion at one end along the second axis. The second button has a second guide portion that remains in contact with the second protrusion. When the second button moves between the second locking position and the second release position, the second protrusion slides on the surface of the second guide portion. The middle seat has a second pivot hole on each of its opposite sides along the second axis. The positioning mechanism includes a second pin. The two ends are respectively inserted into the two second pivot holes.

One end of the second elastic member is inserted into the middle seat. The seat has one end abutting against the side of the second fastener opposite to the second pivot portion. When the second fastener is in the second release position, it pushes the second elastic member to twist and deform. The second elastic member can provide a thrust to move the second fastener to the second locking position. The body includes a second pivot and two second locking members. The second pivot is inserted into the middle seat along the second axis. The two second locking members pass through the first side cover and the second side cover respectively from the side of the first side cover opposite to the middle seat and the side of the second side cover opposite to the middle seat, and are connected to the second pivot by screws. The second pivot portion is sleeved on the second pivot. A non-circular second limiting hole is provided on the side of the middle seat adjacent to the first side cover.The second pivot, near one end adjacent to the first side cover, has a second limiting portion with a shape corresponding to the second limiting hole along its radial outer periphery. This second limiting portion is inserted into the second limiting hole, preventing the second pivot from rotating relative to the central seat.

[0028] Referring to Figures 1 to 7, these are perspective views, exploded perspective views, cross-sectional views, and usage views of the first embodiment of the folding tool with a locking mechanism of the present invention. The folding tool 10 of the present invention includes a body 20, a tool head assembly 30, and a positioning mechanism 40; wherein:

[0029] The tool head assembly 30 includes at least one first tool head 31. One end of the first tool head 31 is provided with a first pivot portion 311. The first pivot portion 311 is pivotally mounted to the body 20 around a virtual first axis C1. At least one first locking portion 312 is provided on the outer periphery of the first tool head 31 and the first pivot portion 311.

[0030] The positioning mechanism 40 includes a first fastener 41 and a first button 42. The first fastener 41 is movably connected to the body 20 and has a first fastening portion 411. The first button 42 is movably connected to the body 20 along the first axis C1 between a first locked position and a first released position. In the first locked position, the first button 42 does not push the first fastener 41 to move, so that the first fastening portion 411 is engaged with the first locking portion 312 and restricts the rotation of the first tool head 31 relative to the body 20. In the first released position, the first button 42 pushes the first fastener 41 to move, so that the first fastening portion 411 is disengaged from the first locking portion 312 and the restriction on the rotation of the first tool head 31 relative to the body 20 is released.

[0031] The first fastener 41 is pivotally mounted on the body 20, and the pivot axis of the first fastener 41 is parallel to the first axis C1.

[0032] The outer periphery of the first fastener 41 is provided with a first protrusion 412 at one end along the axial direction of the first shaft C1. The first button 42 is provided with a first guide 421. The first guide 421 keeps in contact with the first protrusion 412.

[0035] The positioning mechanism 40 includes a first elastic member 44, with a first winding portion 441 between its two ends. The first winding portion 441 is wound at least once and sleeved on the first pin 43. One end of the first elastic member 44 is inserted into the middle seat 21 and the other end abuts against the side of the first fastener 41 opposite to the first pivot portion 311. When the first button 42 is in the first release position, the first fastener 41 pushes the first elastic member 44 to twist and deform. The first elastic member 44 can provide a pushing force to push the first fastener 41 and push the first button 42 to the first locking position through the first fastener 41.

[0036] The body 20 includes a first pivot 24 and two first locking members 25. The first pivot 24 is axially inserted into the middle seat 21 along the first axis C1. The two first locking members 25 pass through the first side cover 22 and the second side cover 23 respectively from the side opposite to the middle seat 21 of the first side cover 22 and the side opposite to the middle seat 21 of the second side cover 23 and are connected to the first pivot 24 by screw locking.

One end of the second elastic member 48 is inserted into the middle seat 21, and the other end abuts against the side of the second fastener 45 opposite to the second pivot portion 321. When the second fastener 45 is in the second release position, the second fastener 45 pushes the second elastic member 48 to twist and deform. The second elastic member 48 can provide a thrust to move the second fastener 45 towards the second locking position.The main body 20 includes a second pivot 26 and two second locking members 27. The second pivot 26 is axially inserted into the middle seat 21 along the second axis C2.
