[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Reference Figure 1-Figure 22 A detachable pot handle comprises a handle body 1, wherein a movable plate 2 is provided inside the handle body 1 and can move forward and backward along the handle body 1, wherein the front end of the movable plate 2 passes through the handle body 1, and a clip is provided at the front end of the movable plate 2, and a sandwich is formed between the clip and the front end surface of the handle body 1. In order to protect the pot and increase friction, a flexible layer 3, such as a silicone layer, a rubber layer, etc., is usually wrapped outside the clip.

[0042] An operating handle 4 is provided on the lower side of the handle body 1, and a handle shaft 5 is fixedly provided at the front portion of the handle body 1. The front portion of the operating handle 4 is rotatably connected to the handle body 1 via the handle shaft 5. A tension spring 6 is provided between the handle shaft 5 and the movable plate 2, and the front end of the tension spring 6 is hooked on the handle shaft 5, and the rear end of the tension spring 6 is hooked on the movable plate 2. Under the elastic force of the tension spring 6, the movable plate 2 tends to move forward, thereby making the interlayer wider. At this time, the detachable pot handle of the present invention can be removed from the pot.

[0043] The rear portion of the operating handle 4 is movably connected to a toggle member 7, and the front portion of the toggle member 7 is movably connected to the rear portion of the operating handle 4. In one embodiment, a through hole is provided at the front portion of the toggle member 7, and a linkage shaft 9 is provided at the rear portion of the operating handle 4. The linkage shaft 9 penetrates into the through hole and has a movable space, thereby achieving the purpose of the movable connection between the two.

[0044] The middle part of the toggle member 7 is rotatably connected to the handle body 1 through a toggle shaft 10, and the rear part of the toggle member 7 is movably connected to the rear part of the moving plate 2. In one embodiment, a shift fork 11 is provided at the rear part of the toggle member 7, and a shift hole is provided at the tail of the moving plate 2, and the shift fork 11 extends into the shift hole, so that the toggle member 7 can drive the moving plate 2 to move through the shift fork 11 after it is rotated.

[0045] After holding the handle body 1 and pinching the operating handle 4, the operating handle 4 rotates around the handle shaft 5 at the front, so that the rear of the operating handle 4 drives the toggle member 7 to rotate around the toggle shaft 10. After the toggle member 7 rotates, the fork 11 at the rear thereof drives the movable plate 2 to move backward, thereby making the interlayer narrower. At this time, the pot can be clamped in the interlayer of the detachable pot handle of the present invention.

[0046] It also includes a locking mechanism and an unlocking mechanism. When the interlayer is narrow, the locking mechanism locks the operating handle 4, thereby locking the toggle member 11 connected to the operating handle 4 to keep the interlayer narrow; the unlocking mechanism is operated to unlock the locking mechanism, and then the movable plate 2 automatically moves forward under the elastic force of the tension spring 6 to make the interlayer wider.

[0047] The locking mechanism comprises: A locking tooth block 12 is also fixed to the rear of the operating handle 4. In one embodiment, the linkage shaft 9 at the rear of the operating handle passes through the locking tooth block 12 and the two are fixed by interference fit or the like. A locking tooth row 13 is provided on the rear end face of the locking tooth block 12. A positioning tooth block 15 is also rotatably connected to the handle body 1 through a positioning shaft 14. The positioning shaft 14 is passed through the lower part of the positioning tooth block 15. The positioning tooth block 15 is located behind the locking tooth block 12, and a positioning spring 16 is provided at the rear of the positioning tooth block 15 to support the positioning tooth block 15 so that it has a tendency to rotate forward. A positioning tooth row 17 is provided on the front end face of the positioning tooth block 15.

[0048] In one embodiment, a mounting block is provided at the tail of the handle body 1, the rear end of the positioning spring 16 is pressed against the mounting block, and the front end of the positioning spring 16 is pressed against the positioning tooth block 15. The toggle shaft 10 is fixedly penetrated on the mounting block, the positioning shaft 14 is penetrated on the mounting block, and the toggle shaft 10 and the positioning shaft 14 are the same shaft. The specific fixed installation method of the mounting block can be: the mounting block is fixed to the handle body 1 by a fixed shaft 19 penetrated therein; a limiting hole 20 is provided on the toggle member 4 and the positioning tooth block 15, and the fixed shaft 19 passes through the limiting hole 20, and the fixed shaft 19 can also play a role in limiting the rotation angle of the toggle member 4 and the positioning tooth block 15.

[0049] After the operating handle 4 is pinched and rotated, the locking tooth block 12 moves until the locking tooth row 13 is engaged with the positioning tooth row 17, thereby locking the operating handle 4. After the locking tooth row 13 is engaged with the positioning tooth row 17, the operating handle 4 can be locked because: since the positioning tooth block 15 is located behind the locking tooth block 12, that is, the positioning tooth block 15 is located at the tail of the handle body 1, the force arm from the positioning shaft 14 of the positioning tooth block 15 to the engagement point is the rear force arm; and the locking tooth block 12 is fixed to the operating handle 4, and the two can be regarded as one body, the shaft of this one-piece is the handle shaft 5, and the force arm from the handle shaft 5 to the engagement point is the front force arm, and the handle shaft 5 is located at the front of the operating handle 4, so it is obvious that the front force arm is much larger than the rear force arm, and the locking tooth block 12 and the positioning tooth block 15 are in a torque balance state, that is, the force of the locking tooth block 12 to escape the engagement lock is much smaller than the locking force of the positioning tooth block 15, so the operating handle 4 can be locked.

[0050] The unlocking mechanism comprises: an unlocking rod 21 capable of moving forward and backward in the handle body 1, a first return spring 27 is arranged between the unlocking rod 21 and the handle body 1, and the unlocking rod 21 has a tendency to move forward under the action of the first return spring 27. The tail of the unlocking rod 21 is aligned with the upper part of the positioning tooth block 15. After the unlocking rod 21 moves backward, the positioning tooth block 15 is pushed to rotate backward by the unlocking rod 21, so that the locking tooth row 13 is disengaged from the positioning tooth row 17 to achieve unlocking.

[0051] In order to drive the unlocking rod 21 to move backward, an unlocking sliding button 8 is slidably provided on the handle 1 , and the unlocking sliding button 8 is exposed on the upper surface of the handle body 1 .

[0052] A positioning block 18 is fixed on the handle body 1 . In this embodiment, a positioning shaft 22 is fixedly penetrated through the positioning block 18 . The positioning block 18 is fixed to the handle body 1 via the positioning shaft 22 .

[0053] The positioning block 18 is provided with a rotatable unlocking plate 23, the lower end of which is rotatably connected to the positioning block 18 via an unlocking plate rotating shaft 24, and the upper part of which is movably connected to the unlocking slide button 8, so that when the unlocking slide button 8 moves backward, it can drive the unlocking plate 23 to rotate around the unlocking plate rotating shaft 24, thereby pushing the unlocking rod 21 to move backward through the unlocking plate 23, thereby pushing the positioning tooth block 15 to rotate backward through the unlocking rod 21, so that the locking tooth row 13 is disengaged from the positioning tooth row 17 to achieve unlocking. In one embodiment, a groove is provided inwardly on the rear end surface of the positioning block, and the unlocking plate 23 is located in the groove, which has a reasonable and compact structure. In one embodiment, a push shaft 25 is fixedly penetrated on the unlocking slide button 8, and a through hole is provided on the upper part of the unlocking plate 23, through which the push shaft 25 passes, so that the unlocking plate 23 can be driven to rotate around the unlocking plate rotating shaft 24 by the push shaft 25.

[0054] In one embodiment, the unlocking rod 21 is provided with a resisting rod 38. When unlocking, the unlocking plate 23 resists the resisting rod 38, thereby pushing the unlocking rod to move backward. In order to reduce wear, a protective sleeve 39 may be provided outside the resisting rod. The handle body 1 is also provided with a safety mechanism to prevent the unlocking slide button 8 from being misoperated. The safety mechanism includes: A safety button 26 is provided on the handle body 1 and can be raised and lowered. The safety button 26 extends from the upper surface of the handle body 1. A second return spring 28 is provided between the safety button 26 and the handle body 1. Under the action of the second return spring 28, the safety button 26 is in a high locking position. At this time, the safety button 26 can block the unlocking slide button 8 from moving backward. After the safety button 26 is pressed downward, the safety button 26 no longer blocks the unlocking slide button 8. In one embodiment, the safety button 26 is located in front of the unlocking slide button 8. The unlocking slide button 8 has a positioning arm 30 extending forward. The positioning arm 30 cooperates with the safety button 26. In one embodiment, the specific cooperation method is: A limiting groove 31 is provided on the bottom surface of the positioning arm 30, and a limiting block 32 corresponding to the limiting groove 31 is provided on the safety button 26; when the safety button 26 is in a high locking position under the action of the second return spring 28, the limiting block 32 is located in the limiting groove 31, thereby preventing the unlocking slide button 8 from moving backward; after the safety button 26 is pressed downward, the limiting block 32 disengages from the limiting groove 31, thereby the unlocking slide button 8 can move backward smoothly.

[0055] In one embodiment, in order to ensure that the safety button 26 can be positioned after being pressed down, so as to facilitate the operation of the unlocking slide button 8 to move backward, a lock tongue 33 that can move forward and backward is further provided in the positioning block 18, and the lock tongue 33 has a stopper 34 extending forward, and the safety button 26 has a locking shoulder 35 extending backward; A third return spring 29 is provided between the lock tongue 33 and the positioning block 18. Under the action of the third return spring 29, the lock tongue 33 extends forward from the positioning block and abuts against the safety button 26. After the safety button 26 is pressed downward, the safety button 26 pushes the lock tongue 33 backward until the locking boss 35 of the safety button is located below the stopper 34 of the lock tongue. At this time, the stopper 34 blocks the locking boss 35, so that the safety button 26 remains in a low released position so that the safety button 26 no longer blocks the unlocking slide button 8. In one embodiment, in order to enable the lock tongue 33 to be driven back smoothly when the safety button 26 is pressed down, the front end face of the lock tongue 33 has a first inclined surface 40 tilted backward, and the safety button 26 has a second inclined surface 41 adapted to the first inclined surface 40. Under the action of the third return spring 29, the lock tongue 33 extends forward from the positioning block and the first inclined surface 40 is abutted against the second inclined surface 41 of the safety button 26. When the safety button 26 is pressed down, the lock tongue 33 can be pushed back smoothly under the interaction of the first inclined surface 40 and the second inclined surface 41.

[0056] The unlocking slide button 8 is provided with a downwardly protruding block 36, and the locking tongue 33 has a push groove 37. The block 36 is located in the push groove 37. When the unlocking slide button 8 moves backward to unlock, the block 36 moves to the end of the push groove 37 until it pushes the locking tongue 33, thereby driving the locking tongue 33 to move backward so that the stopper 34 of the locking tongue no longer blocks the locking boss 35, so that the safety button 26 rises up under the action of the second return spring 28 and presses on the positioning arm 30.

[0057] After the unlocking slide button 8 is reset under the action of the first reset spring 27, the limit block 32 enters the limit groove 31 again. In this way, the whole process of the interlayer narrowing and locking, and the interlayer widening again after unlocking is completed.
