[0003] The existing detachable pot handles still have the following disadvantages: 1. Based on the structural design of the unlocking mechanism, a large force is required to achieve the unlocking operation; 2. The unlocking mechanism is located on the upper surface of the handle, which is prone to accidental pressing operations; 3. The ease of operation needs to be improved. Summary of the Invention

[0004] In order to overcome the above-mentioned deficiencies of the existing detachable pot handle, the utility model provides a detachable pot handle with a simpler structure.

The positioning tooth block is located behind the locking tooth block. A positioning spring is provided at the rear of the positioning tooth block to support the positioning tooth block so that it has a tendency to rotate forward. A positioning tooth row is provided on the front end surface of the positioning tooth block.

[0013] After pinching the operating handle and rotating it, the locking tooth block moves accordingly until the locking tooth row engages with the positioning tooth row, thereby locking the operating handle;

[0014] The unlocking mechanism includes: an unlocking rod capable of moving back and forth in the handle body, a return spring being provided between the unlocking rod and the handle body, and the unlocking rod tends to move forward under the action of the return spring, and the tail of the unlocking rod is aligned with the upper part of the positioning tooth block; a rotatable unlocking lever is also provided in the handle body, the rear part of the unlocking lever is rotationally connected to the handle body, the front end of the unlocking lever is rotationally connected to the middle part of the unlocking lever, and the front part of the unlocking lever extends from the side of the handle body, and moving the unlocking lever can drive the unlocking rod to move backward, thereby pushing the positioning tooth block to rotate backward through the unlocking rod, so that the locking tooth row is disengaged from the positioning tooth row to achieve unlocking.

[0015] Furthermore, a through hole is provided at the front of the toggle member, and a linkage shaft is provided at the rear of the operating handle. The linkage shaft penetrates into the through hole and has a movable space.

[0016] Furthermore, a shift fork is provided at the rear of the shifting member, a shift hole is provided at the tail of the movable plate, and the shift fork extends into the shift hole.

[0017] Furthermore, a mounting block is provided at the tail portion of the handle body, the rear end of the positioning spring is pressed against the mounting block, and the front end of the positioning spring is pressed against the positioning tooth block.

[0018] Furthermore, the shifting shaft is fixedly provided on the mounting block, and the positioning shaft is provided on the mounting block.

[0037] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0038] Reference Figures 1-12A detachable pot handle includes a handle body 1, a movable plate 2 disposed within the handle body 1 and capable of moving forward and backward along the handle body 1. The front end of the movable plate 2 extends through the handle body 1, and a clip is disposed at the front end of the movable plate 2, forming a sandwich layer between the clip and the front end of the handle body 1. To protect the pot and increase friction, a flexible layer 3, such as a silicone layer or rubber layer, is typically wrapped around the clip.

[0039] 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 part of the handle body 1. The front part 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. 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 handle of the pot of the utility model can be removed from the pot.

[0040] The rear part of the operating handle 4 is movably connected to a toggle member 7, and the front part of the toggle member 7 is movably connected to the rear part of the operating handle 4. In one embodiment, a through hole 8 is provided at the front part of the toggle member 7, and a linkage shaft 9 is provided at the rear part of the operating handle 4. The linkage shaft 9 penetrates into the through hole 8 and has a movable space, thereby achieving the purpose of movably connecting the two.

[0041] The middle portion of the toggle member 7 is rotatably connected to the handle body 1 via a toggle shaft 10, and the rear portion of the toggle member 7 is movably connected to the rear portion of the movable plate 2. In one embodiment, a shift fork 11 is provided at the rear portion of the toggle member 7, and a shift hole is provided at the rear portion of the movable plate 2. The shift fork 11 extends into the shift hole, so that when the toggle member 7 is rotated, the movable plate 2 can be moved via the shift fork 11.

[0042] 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 its toggle shaft 10. After the toggle member 7 rotates, the fork 11 at the rear thereof toggles 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 utility model.

[0043] 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; operating the unlocking mechanism to unlock the locking mechanism, the movable plate 2 automatically moves forward under the elastic force of the tension spring 6 to make the interlayer wider.

[0044] The locking mechanism comprises:

[0045] 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. The rear end face of the locking tooth block 12 is provided with a locking tooth row 13; the handle body 1 is also rotatably connected to a positioning tooth block 15 through a positioning shaft 14. The positioning shaft 14 is provided at 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.

[0046] In one embodiment, a mounting block 18 is provided at the tail end of the handle body 1, the rear end of the positioning spring 16 is pressed against the mounting block 18, and the front end of the positioning spring 16 is pressed against the positioning tooth block 15. The toggle shaft 10 is fixedly provided on the mounting block 18, and the positioning shaft 14 is provided on the mounting block 18. The toggle shaft 10 and the positioning shaft 14 are the same shaft. The specific fixing and installation method of the mounting block 18 can be: the mounting block 18 is fixed to the handle body 1 by a fixed shaft 19 provided 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. The fixed shaft 19 can also serve to limit the rotation angle of the toggle member 4 and the positioning tooth block 15.

[0047] After the operating handle 4 is pinched and rotated, the locking tooth block 12 moves accordingly until the locking tooth row 13 engages with the positioning tooth row 17, thereby locking the operating handle 4. The reason why the operating handle 4 can be locked after the locking tooth row 13 engages with the positioning tooth row 17 is that 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 rear 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 considered as one piece. The rotation axis 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. Since the handle shaft 5 is located at the front of the operating handle 4, it is obvious that the front force arm is much greater than the rear force arm, and the locking tooth block 12 and the positioning tooth block 15 are in a torque equilibrium state, that is, the force of the locking tooth block 12 attempting 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.

[0048] The unlocking mechanism includes an unlocking lever 21 capable of moving forward and backward within the handle body 1. A return spring 24 is provided between the unlocking lever 21 and the handle body 1. Under the action of the return spring 24, the unlocking lever 21 tends to move forward. The tail of the unlocking lever 21 is aligned with the upper portion of the positioning tooth block 15. The handle body 1 is also provided with a rotatable unlocking lever 22. The rear portion of the unlocking lever 22 is rotatably connected to the handle body 1. The front portion of the unlocking lever 21 is rotatably connected to the middle portion of the unlocking lever 22. The front portion of the unlocking lever 22 extends from the side of the handle body 1. Activating the unlocking lever 22 drives the unlocking lever 21 to move backward, thereby pushing the positioning tooth block 15 to rotate backward through the unlocking lever 21, causing the locking teeth 13 to disengage from the positioning teeth 17, thereby achieving unlocking. In one embodiment, the positioning tooth block 15 extends an unlocking protrusion 23 upward, and the unlocking rod 21 faces the unlocking protrusion 23. After the unlocking rod 21 moves backward, the unlocking rod 21 pushes the unlocking protrusion 23 backward to rotate the positioning tooth block 15 backward.
