DETAILED DESCRIPTION

[0020] Specifically, the first connecting member includes a mounting plate 16, and the fixing device is connected to the iron pot component through the mounting plate 16. One side of the mounting plate 16 is a plate with an arc-shaped contact surface, and the arc-shaped contact surface is arranged to fit the iron pot component. A plurality of fixing holes 1601 are vertically arranged on the mounting plate 16, and two bolt holes are vertically arranged on the support plate 1. The support plate 1 is fixedly connected to the mounting plate 16 by bolts passing through two of the fixing holes 1601, and the mounting plate 16 is fixedly connected to the iron pot component through other fixing holes 1601. The support plate 1 is a rectangular plate body, which is vertically arranged on the mounting plate 16, and a fixing clamping mechanism is arranged on its lower side. The fixing clamping mechanism is a fixing bolt 9, and the fixing bolt 9 is arranged on the side of the support plate 1 away from the mounting plate 16.

[0021] The fixing rod 6 is arranged opposite to the support plate 1 through the connecting block 3. A movable clamping mechanism is arranged at the same height as the fixed clamping mechanism on the lower side of the fixing rod 6. The movable clamping mechanism includes a movable bolt 8, which is arranged at the lower end of the fixing rod 6. A cube fixing block is arranged at the lower end of the fixing rod 6. A through hole is arranged on the fixing block. The bolt passes through the through hole and is connected with the movable bolt 8. The movable bolt 8 is arranged on a side close to the support plate 1 and is arranged opposite to the fixing bolt 9. A fixing nut 17 is also arranged on the bolt to prevent thread slipping. The fixing nut 17 and the movable bolt 8 are arranged on both sides of the fixing block respectively.

[0022] A bottom plate 2 is horizontally arranged between the connection block 3 and the support plate 1, and the bottom plate 2 is welded to the support plate 1. Two connection blocks 3 are symmetrically arranged on both sides of the upper end of the fixing rod 6, sandwiching the fixing rod 6 in the middle, and the three are connected by a rotating shaft, and the side of the connection block 3 close to the bottom plate 2 is bent outward, and the bent part is fixed to the bottom plate 2 by bolts.

[0023] The operating handle 4 is arranged on the opposite side of the two connecting blocks 3, and one end of the operating handle 4 is forked with a clamping part, which is composed of two clamping pieces 401. The two connecting blocks 3 and the fixing rod 6 are arranged between the two clamping pieces 401, and the two clamping pieces 401 are rotatably connected with the two connecting blocks 3 through a rotating shaft. The connecting block 3 is provided with an angle limit block 7, which is arranged on the upper side of the connecting end of the two clamping pieces 401 and the connecting block 3 to limit the upward rotation angle of the operating handle 4. An avoidance groove is protruding outwards from the middle of the two clamping pieces 401, and the lock tongue is arranged in the avoidance groove.

[0024] See also Figure 3 The lock tongue includes two locking plates 5, a spacer ring 13 and two lock tongue rotating shafts. The two locking plates 5 are arranged on both sides of the fixed rod 6, and are rotatably connected to the fixed rod 6 through the first lock tongue rotating shaft 14, and are rotatably connected to the clamping plate 401 through the second lock tongue rotating shaft 15. The spacer ring 13 is arranged on the second lock tongue rotating shaft 15 and is arranged between the two locking plates 5. The length of the spacer ring 13 is the same as the width of the fixed rod 6.

[0025] The limiting block is composed of two limiting protrusions 501, which are arranged on the lower side of the two locking plates 5 and close to one side of the second lock tongue shaft 15. The distance between the two limiting protrusions 501 gradually decreases from top to bottom until they fit together.

[0026] The second connecting member includes a slider 10 and a support arm 11. The slider 10 is a rectangular plate with a base. The base is horizontally arranged at the lower side of the plate. The base is concavely buckled on the support arm 11. Two adjustment slots 101 are respectively arranged on the two side walls of the base. Bolt holes are arranged on the side walls of the support arm 11. The adjustment bolts 12 pass through the adjustment slots 101 and are arranged in the bolt holes to fix the slider 10 on the support arm 11. The upper end of the slider 10 is arranged between the fixed clamping mechanism and the movable clamping mechanism. The slider 10 is fitted with the fixed bolt 9. The movable bolt 8 presses the slider 10 by rotating the operating handle 4. The support arm 11 is connected to the shearing mechanism, thereby fixing the shearing mechanism.

[0027] Working process:

[0028] The support arm 11 is connected to the shearing mechanism by bolts, the mounting plate 16 fixes the support plate 1 to the iron pot part, the slider 10 is placed between the movable bolt 8 and the fixed bolt 9, and the relative position of the slider 10 and the support arm 11 is adjusted by the adjustment slot 101 on the support arm 11. The operating handle 4 is turned downward to drive the locking tongue and the fixed rod 6 to rotate downward until the limiting protrusion 501 abuts against the fixed rod 6. At this time, the movable bolt 8 presses the slider 10, and the entire fixing device forms a self-locking, so that the shearing mechanism is fixed relative to the iron pot part without shaking.

[0029] The operating handle 4, the locking tongue, the connecting block 3, and the fixing rod 6 can be regarded as a crank-connecting rod mechanism as a whole, the operating handle 4 is the driving shaft, and the fixing rod 6 rotates with the rotation of the operating handle 4. When it rotates to the vertical direction, the fixing rod 6 is blocked by the second connecting member and no longer moves. At this time, the operating handle 4 can only move in the opposite direction, that is, the structure is locked. In actual situations, in order to prevent the operating handle 4 from rotating due to mechanism vibration or other factors, the operating handle 4 continues to be pressed down to stretch itself until the limiting protrusion 501 on the lower side of the locking tongue abuts against the fixing rod 6, the structure is locked, and the structural dead point of the crank-connecting rod determines that the entire structure cannot move anymore.

[0030] After the crank-connecting rod mechanism rotates to a certain angle, the operating handle 4 reaches a "dead point" and cannot be rotated any further. Of course, in actual situations, after reaching the dead point, continued application of pressure can change the length of the operating handle 4 with a certain elasticity. The middle of the two clamping pieces 401 protrudes outward to make it have a certain elasticity, or the selection of materials can also make it have a certain elasticity. When crossing the "dead point", until the lock tongue abuts against the fixed rod 6, at this time, without being subjected to external pressure, the operating handle 4 restores its length, and without deliberately applying pressure, it can ensure that the operating handle 4 maintains the original working condition, that is, the locked state.

[0031] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
