Description

Technical Field

[0001] The invention relates to the technical field of pulverizers, and in particular to a knife adjusting tool for a membrane pulverizer. Background Art

[0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. There are four external forces applied to the solid during the crushing process: shearing, impact, rolling, and grinding. Shearing is mainly used in coarse crushing (crushing) and pulverizing operations, and is suitable for crushing or pulverizing tough or fibrous materials and large blocks of materials; impact is mainly used in pulverizing operations, and is suitable for crushing brittle materials; rolling is mainly used in high-fineness crushing (ultrafine crushing) operations, and is suitable for ultrafine crushing of materials of most properties; grinding is mainly used in ultrafine crushing or ultra-large crushing equipment, and is suitable for further crushing operations after crushing operations; combined with the above-mentioned crushing of plastic films and other related membranes, shearing action must be applied to complete the crushing, and if a gap appears in the crushing knife after long-term non-stop operation, the knife must be replaced.

[0003] In the prior art, for the crushing of plastic films and other related membranes, if the setting method of completely overlapping the blade parts of the moving and fixed knives when they are in contact is still adopted, only single-point contact occurs when the moving and fixed knives shear the membrane, and there is a risk of knife entanglement. Therefore, relevant technical personnel have adopted a "human" shaped moving knife structure in conjunction with the corresponding fixed knife. However, the moving knife structure and the knife holder are an integrated fixed structure that cannot meet the needs of crushing membranes of different sizes. When the knife is worn after long-term operation, it can only be replaced together with the knife holder, and it is impossible to replace or adjust the knife separately. For this reason, the present application proposes a solution, which separates the knife holder from the moving knife and uses the knife adjusting tool to pre-adjust the folding angles of adjacent moving knives. After all the moving knife adjustments are completed at one time outside the machine, it can be used without adjusting the gap between the fixed and moving knives. Summary of the invention

[0004] The object of the present invention is to provide a knife adjusting tool for a film crusher, which is used to solve the problem that it is impossible to complete separate knife change and quick knife adjustment during the crushing process of waste film materials such as plastic film; through the design of a phase-separated knife holder and moving knife structure, a right-angled triangular pyramid structure composed of a support plate, a limit rod and an angle plate is used to achieve "radial" fixation of the moving blade, and then assisted by a ball head rod and a multi-directional pressure plate to fix the moving blade on the knife holder "axially". The combination of the two together constitutes a double fixing method to achieve absolute limitation of the installation position of the moving blade, that is, a pair of adjacent moving blades directly complete gap matching with the fixed blade matched with the moving blade after changing the folding angle, and can be used after all moving knife adjustments are completed at one time outside the machine, without the need to adjust the gap between the fixed and moving knives, and is suitable for crushing plastic films of different thicknesses.

[0005] The object of the present invention can be achieved by the following technical scheme: a knife adjustment tool for a diaphragm crusher, comprising a pair of hinged support plates, the upper surfaces of the pair of support plates are both provided with moving blades with inner end sides abutting against each other, both ends of the hinged parts of the support plates are provided with limit assemblies for positioning the folding angle of the moving blades, the support plates are provided with a limit rod for radially positioning the moving blades through a sliding hole, and can move horizontally based on the upper surface of the support plates, and the outer end of the limit rod is connected with an angle plate abutting against the moving blades;

[0006] The limiting assembly comprises a square long groove and an oblong groove which are arranged at the end of the support plate hinge and are aligned one by one, the square long groove and the oblong groove constitute a "T"-shaped groove, the square long groove and the oblong groove are jointly plugged with a positioning ring seat for positioning the hinge at a folding angle, and a T-shaped plug rod which is integrally connected to the square long groove and the oblong groove is installed on the positioning ring seat; the limiting assembly also comprises a blind hole arranged in the middle of the outer end of the support plate hinge, and a screw rod which is threadedly connected to the blind hole is abutted on the outside of the positioning ring seat; the end of the screw rod which passes through the positioning ring seat and extends to the outside is installed with a hexagonal rod which can be twisted with a wrench, and when the screw rod is threadedly connected to the blind hole, the hexagonal rod abuts against the outer surface of the positioning ring seat;

[0007] A ball head rod is embedded and swingably mounted on the upper surface of one side of the support plate close to the sliding hole, and a multi-directional pressure plate abutting against the upper surface of the moving blade is sleeved on the upper end of the ball head rod.

[0008] It is further configured as follows: a sliding rod slidably connected to the sliding hole is installed at the bottom of the limit rod, the limit rod moves horizontally along the sliding hole on the upper surface of the support plate through the sliding rod, and a bolt passing through the sliding hole is installed in the middle of the lower surface of the sliding rod.

[0009] It is further configured as follows: a spherical groove is opened at a portion of the support plate corresponding to the ball head rod, deflection grooves are extended on both sides of the support plate corresponding to the spherical groove, and the ball head rod tilts toward both sides of the deflection groove with the spherical groove as a rotation fulcrum.

[0010] It is further configured as follows: a triangular deflection hole is opened on the swinging track of the ball head rod through the movable blade, and the ball head rod passes through the deflection hole and extends to the upper external threaded sleeve connected with a nut that abuts against the upper surface of the movable blade.

[0011] It is further configured as follows: a second deflection hole vertically aligned with the ball head rod is provided on the multi-directional pressure plate, and a steering ball rotatably connected to a fixed plate is fixedly connected to the middle of the outer end of the multi-directional pressure plate.

[0012] It is further configured as follows: the limit rod is a strip columnar structure, the angle plate is installed inwardly at the middle of the outer end of the limit rod, and the limit rod and the angle plate are fixedly connected at the outer end of the upper surface of the support plate by the bolts.

[0013] It is further configured that: the support plate, the limiting rod and the angle plate are combined to form a hollow right-angled triangular pyramid structure as a whole, and the right-angle space formed is used to accommodate the movable blade to be adjusted.

[0014] A method for using a knife adjusting tool for a diaphragm crusher comprises the following steps:

[0015] Step 1: Determine the expansion angle of the moving blade according to the thickness of the plastic film to be crushed, and first adjust the expansion angle of the support plate;

[0016] Step 2: Unscrew the screw rod through the hexagonal rod and pull out the positioning ring seat. At this time, the T-shaped plug rod on the positioning ring seat is separated from the "T"-shaped groove composed of the square long groove and the flat long groove. Then rotate the support plate to make the square long groove and the flat long groove correspond to the required matching position, and then insert the positioning ring seat into the "T"-shaped groove composed of the square long groove and the flat long groove with the changed position through the T-shaped plug rod to complete the positioning. The hexagonal rod is used to screw the screw rod into the blind hole, so as to complete the fixation of the support plate after adjusting the angle;

[0017] Step 3: Pass a pair of moving blades through the ball head rod outside the machine and place them on the support plate in a manner that the middle of one side of the inner blade tip is aligned. At the same time, move the limit rod to drive the angle plate to abut against the blade side of the moving blade, and lock the bolt down to the nut on the lower side of the sliding hole, thereby completing the "radial" fixation of the moving blade on the support plate;

[0018] Step 4: The entire tooling is transferred into the machine. The ball rod is passed through the multi-directional pressure plate from bottom to top. Then the nut on the ball rod forms abutment limit for the moving blade. Finally, the nut on the upper side of the ball rod completes the locking of the multi-directional pressure plate. At this time, the moving blade is "axially" fixed on the multi-directional pressure plate and the tool holder shaft.

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention aims at the problem that it is impossible to complete the independent blade change and quick blade adjustment during the crushing process of waste film such as plastic film; through the design of the separated blade holder and moving blade structure, the "radial" fixation of the moving blade is achieved by the right-angle triangular pyramid structure composed of the support plate, the limit rod and the angle plate, and the "axial" fixation of the moving blade on the blade holder is supplemented by the ball head rod and the multi-directional pressure plate. The combination of the two together forms a double fixing method to achieve the absolute limitation of the installation position of the moving blade, that is, the gap matching of the adjacent pair of moving blades and the fixed blade matched with the moving blade is directly completed after the folding angle of the adjacent pair of moving blades is changed, and the folding angle adjustment of all the moving blades is completed at one time outside the machine, and the installation can be quickly carried out without adjusting the gap between the fixed and moving blades;

[0021] 2. During the left and right deflection of the ball head rod, since the ball head rod uses the bottom ball head structure and the spherical groove as the rotation points, and the deflection groove provides a deflection direction guide for the ball head rod, the ball head rod can complete the deflection and displacement through the deflection groove. Regardless of the deflection angles of the support plate and the movable blade, the movable blade can be effectively limited and fixed on the tool holder shaft. After the folding angle of the movable blade is fixed and the installation is completed, the blade presents a progressive contact mode with the fixed blade during rotation, thereby effectively preventing the entanglement phenomenon during the crushing process of plastic films of different thicknesses and reducing the risk of "knife entanglement".

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0038] Aiming at the problem that it is impossible to complete the single knife change and quick knife adjustment during the crushing process of waste film such as plastic film, the present invention discloses a knife adjustment tool for a film crusher, please refer to Figure 1 - Figure 3 and Figure 7As shown, it comprises a pair of support plates 1 which are hinged to each other, and movable blades 4 which are abutted against each other at the inner end sides are placed on the upper surfaces of the pair of support plates 1, and inner blade tips 41 are arranged at the ends of the movable blades 4 which are close to each other, and outer blade tips 42 which are smoothly connected to the inner blade tips 41 are arranged at the outer ends of the movable blades 4, and limiting components for positioning the folding angle of the movable blades 4 are arranged at both ends of the hinged parts of the support plates 1, and the support plates 1 are provided with a limiting rod 2 which is used for radial positioning of the movable blades 4 through the sliding holes 7 and can be horizontally moved based on the upper surface of the support plates 1, and the outer ends of the limiting rods 2 are connected with an angle plate 3 which abuts against the movable blades 4, and a sliding rod 8 which is slidably connected with the sliding holes 7 is installed at the bottom of the limiting rod 2, and the limiting rod 2 moves horizontally along the sliding holes 7 on the upper surface of the support plates 1 through the sliding rod 8, and a bolt 9 which passes through the sliding holes 7 is installed in the middle of the lower surface of the sliding rod 8, and the bolt 9 passes through the sliding holes 9 and extends to the bottom and is threadedly connected with a nut, and the outer diameter of the nut is larger than the width of the sliding holes 7;

[0039] See also Figure 4 and Figure 5 As shown, the limiting assembly includes a square long groove 15 and a flat long groove 16 which are arranged at the hinge end of the support plate 1 and are aligned one by one, and a blind hole 20 is opened in the middle of the outer end of the hinge shaft, and the square long groove 15 and the flat long groove 16 form a "T"-shaped groove, and the square long groove 15 and the flat long groove 16 are jointly inserted with a positioning ring seat 17 for positioning the hinge at a folding angle, and the positioning ring seat 17 is abutted with a screw 10 threadedly connected to the blind hole 20;

[0040] Reference Figure 5 and Figure 6 As shown, a T-shaped plug rod 18 aligned with the elongated slot 16 is installed on the positioning ring seat 17, and the T-shaped plug rod 18 matches the "T"-shaped slot composed of the square elongated slot 15 and the elongated slot 16. A through hole 19 for inserting the screw rod 10 is opened in the middle of the positioning ring seat 17, and the screw rod 10 passes through the positioning ring seat 17 and extends to the outer end thereof, and a hexagonal rod 6 that can be twisted with a wrench is installed;

[0041] See also Figure 8 and Fig. 9 As shown, a ball head rod 12 is embedded and swingably installed on the upper surface of one side of the support plate 1 close to the sliding hole 7, and a spherical groove 14 is opened on the support plate 1 corresponding to the ball head rod 12. The spherical groove 14 is located in the middle of the support plate 1, and a deflection hole 11 is opened on the movable blade 4 through the swinging trajectory of the ball head rod 12. The upper end of the ball head rod 12 is sleeved with a multi-directional pressure plate 21 that abuts against the upper surface of the movable blade 4.

[0042] See also Fig.10 - Fig.13As shown, it is a schematic diagram of the structure of the tool holder shaft in the present invention applied to, including but not limited to, a diaphragm crusher; the tool holder shaft includes a tool holder 24 and a fixed plate 26, and a ramp for installing the tool adjustment tool of the present invention is provided on one side of the tool holder 24 close to the fixed plate 26, and both sides of the edges of the support plate 1 after unfolding are in contact with the surface of the ramp, and the diaphragm crusher has fixed blades 25 symmetrically arranged on both sides of the rotation track of the moving blade 4, and a blade middle portion 251 is arranged in the middle of the blade portion 5 close to the fixed blade 25, and two ends of the fixed blade 25 corresponding to the blade middle portion 251 are provided The blade edge 252, when the movable blade 4 rotates with the blade holder shaft, the inner blade tips 41 of the pair of movable blades 4 coincide with the running track of the blade middle 251 of the fixed blade 25, and the outer blade tips 42 of the pair of movable blades 4 coincide with the running track of the blade edge 252 of the fixed blade 25, so that the entire scheme determines the adjustment of the folding angle of the movable blade 4 with the initially set fixed blade 25, and after the folding angle of the movable blade 4 is adjusted, the gap setting of the fixed and movable blades can be quickly realized, so as to adapt to different plastic films of different thicknesses to complete fine crushing and reduce the risk of winding;

[0043] The gap adjustment between the moving blade 4 and the fixed blade 25 is mainly expressed by the folding angle of the moving blade 4. Therefore, when solving the "fast blade adjustment process" in the "problem of being unable to complete the single blade change and fast blade adjustment", the gap adjustment can be achieved by "locking" the moving blade 4 after adjustment, and the "single blade change process" can be quickly achieved after releasing the above double locking, which is described in detail below;

[0044] When the support plate 1 is in the initial state, the expansion angle of a pair of support plates 1 is 180°. The expansion angle of the moving blade 4 is determined according to the thickness of the plastic film to be crushed. First, the expansion angle of the support plate 1 is adjusted: the screw 10 is unscrewed through the hexagonal rod 6, and the positioning ring seat 17 is pulled out. At this time, the T-shaped plug rod 18 on the positioning ring seat 17 is disengaged from the "T"-shaped groove composed of the square long groove 15 and the flat long groove 16, and then the support plate 1 is rotated to make the square long groove 15 and the flat long groove 16 correspond to the required matching position, and then the positioning ring seat 17 is inserted into the "T"-shaped groove composed of the square long groove 15 and the flat long groove 16 of the changed position through the T-shaped plug rod 18 to complete the positioning, and the screw 10 is screwed into the blind hole 20 by the hexagonal rod 6, so that the expansion angle of the support plate 1 is adjusted; then a pair of moving blades 4 are passed through the ball head The rod 12 is mounted on the support plate 1 in a manner that the middle of one side edge of the inner blade tip 41 is aligned, and at the same time, the limit rod 2 is moved to drive the angle plate 3 to abut against the blade side of the movable blade 4, and the locking bolt 9 is extended to the nut on the lower side of the sliding hole 7, thereby completing the "radial" fixation of the movable blade 4 on the support plate 1, and the ball head rod 12 continues to extend to the locking of the nut on the upper side of the movable blade 4. At this time, the movable blade 4 is "axially" fixed by the multi-directional pressure plate 21 and the tool holder shaft, and the dual fixing method of "radial" locking and "axial" locking is combined to achieve the absolute limitation of the installation position of the movable blade 4, that is, the adjacent pair of movable blades 4 directly complete the gap matching with the fixed blade 25 matched with the movable blade 4 after changing the folding angle, so that it can adapt to plastic films of different thicknesses for crushing work;

[0045] The "separate tool changing process" is as follows: when changing tools, the fixed blade 25 is preliminarily set in advance, and the setting of all the fixed blades 25 is completed "outside the machine", and the movable blade 4 is adjusted at an angle on the support plate 1 to form a gap matching with the fixed blade 25, and finally the fixed blade 25 and the movable blade 4 are directly installed as a whole. During the whole tool changing process, the fixed blade 24 is pre-set. If a separate tool change is required, only the installation and folding angle of one group of movable blades 4 needs to be pre-adjusted, and then the installation can realize separate tool change and quick tool change. The advantage is that the tool holder is separated from the movable knife and the knife adjusting tool is used to pre-adjust the folding angle of adjacent movable knives. After all the movable knives are adjusted at one time outside the machine, they can be used without adjusting the gap between the fixed and movable knives. Embodiment 2:

[0046] This embodiment is based on the first embodiment, in which the steering fixing structure of the multi-directional pressure plate 21 is structurally optimized, and the movable connection between the ball head rod 12 and the multi-directional pressure plate 21 is set to be movable, so as to facilitate the full range of limit when the movable blade 4 presents different tilting and deflection angles, as follows:

[0047] Reference Fig. 9As shown, the middle part of the outer end of the multi-directional pressure plate 21 is fixedly connected with a steering ball 22, and the steering ball 22 is rotatably connected with the fixed plate 26 on the tool holder 24. When the multi-directional pressure plate 21 follows the nut to be screwed downward, the multi-directional pressure plate 21 forms a multi-directional rotation with the fixed plate 26 through the steering ball 22, and no matter what folding angle the movable blade 4 is at, the movable blade 4 can be effectively limited and fixed on the tool holder shaft; the multi-directional pressure plate 21 is provided with a second deflection hole 23 at a position corresponding to the position where the ball head rod 12 passes through, and the multi-directional pressure plate 21 passes through the second deflection hole 23 through the ball head rod 12 3 can realize left and right deflection; the support plate 1 is provided with deflection grooves 13 extending from both sides corresponding to the spherical groove 14, and the deflection grooves 13 extend to both sides through the spherical groove 14 with the same length. During the above-mentioned left and right deflection process, the ball head rod 12 uses the bottom ball head structure and the spherical groove 14 as the rotation point, and the deflection groove 13 provides the deflection direction guide of the ball head rod 12, so that the ball head rod 12 can complete the deflection and displacement through the deflection groove 13, and no matter what the deflection angle of the support plate 1 and the movable blade 4 is, the movable blade 4 can be effectively limited and fixed on the tool holder shaft;

[0048] Reference Figure 5 As shown, the outer side of the sleeve of the hinge of the support plate 1 is designed as a hexagonal structure, and the middle section of the sleeve is designed as a defective structure. When a pair of support plates 1 rotate relative to each other, the hinge sleeve part is exposed and is located below the butt joint edge of the pair of support plates 1. At this time, the hinge sleeve part with a hexagonal structure design will not hinder the folding and butt joint of the support plates 1;

[0049] Reference Figure 8 As shown, the cross section of the deflection hole 11 on the movable blade 4 is triangular, and the upper opening width of the deflection hole 11 is larger than the bottom opening width. The ball head rod 12 passes through the deflection hole 11 and can complete the left and right deflection with the bottom opening.

[0050] In combination with Embodiment 1 and Embodiment 2, the method for using the tool adjustment tool comprises the following steps:

[0051] Step 1: Determine the deployment angle of the moving blade 4 according to the thickness of the plastic film to be crushed, first adjust the deployment angle of the support plate 1, at this time the entire blade adjustment tool is outside the crusher;

[0052] Step 2: Unscrew the screw 10 through the hexagonal rod 6 and pull out the positioning ring seat 17. At this time, the T-shaped plug rod 18 on the positioning ring seat 17 is separated from the "T"-shaped groove composed of the square long groove 15 and the flat long groove 16. Then rotate the support plate 1 so that the square long groove 15 and the flat long groove 16 correspond to the required matching position, and then insert the positioning ring seat 17 into the "T"-shaped groove composed of the square long groove 15 and the flat long groove 16 with the changed position through the T-shaped plug rod 18 to complete the positioning. The screw 10 is screwed into the blind hole 20 by the hexagonal rod 6. In this way, the fixing of the support plate 1 after the angle is adjusted is completed. The entire angle adjustment process is simple to operate and can be quickly installed without the guidance of professionals;

[0053] Step 3: Outside the machine, a pair of moving blades 4 are passed through the ball head rod 12 and mounted on the support plate 1 in a manner that the middle of one side of the inner blade tip 41 is aligned, and at the same time, the limit rod 2 is moved to drive the angle plate 3 to abut against the blade side of the moving blade 4, and the locking bolt 9 is lowered to the nut on the lower side of the sliding hole 7. After tightening the nut 9 to a strained state, the "radial" fixation of the moving blade 4 on the support plate 1 is completed;

[0054] Step 4: The entire tooling is transferred into the machine, and the ball head rod 12 is passed through the multi-directional pressure plate 21 from bottom to top. Then the nut 9 on the ball head rod 12 is tightened. After the nut 9 forms abutment limit on the moving blade 4, the nut 9 on the upper side of the ball head rod 12 finally completes the locking of the multi-directional pressure plate 21. At this time, the moving blade 4 is "axially" fixed on the multi-directional pressure plate 21 and the tool holder shaft.

[0055] In summary: the knife adjustment tooling proposed in this scheme is designed with a separate knife holder and moving knife structure, and the right-angled triangular pyramid structure composed of the support plate 1, the limit rod 2 and the angle plate 3 achieves the "radial" fixation of the moving blade 4, and then the ball head rod 12 and the multi-directional pressure plate 21 are used to fix the moving blade 4 on the knife holder in an "axial" manner. The combination of the two together forms a double fixing method to achieve an absolute limit on the installation position of the moving blade 4, that is, after changing the folding angle, a pair of adjacent moving blades 4 and the fixed blade 25 matched with the moving blade 4 directly complete the gap matching, and after the folding angle adjustment of all moving knives is completed at one time outside the machine, it can be quickly installed without adjusting the gap between the fixed and moving knives;

[0056] And in the process of the left and right deflection of the ball head rod 12, since the ball head rod 12 uses the bottom ball head structure and the spherical groove 14 as the rotation point, and the deflection groove 13 provides a deflection direction guide for the ball head rod 12, the ball head rod 12 can complete the deflection and displacement through the deflection groove 13, no matter what the deflection angle of the support plate 1 and the movable blade 4 is, the movable blade 4 can be effectively limited and fixed on the tool holder shaft, and after the folding angle of the movable blade 4 is fixed and the cutting and installation are completed, the blade presents a progressive contact mode with the fixed blade 25 during rotation, thereby effectively preventing the entanglement phenomenon during the crushing process of plastic films of different thicknesses and reducing the risk of "knife entanglement".

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The knife adjusting tool for a film crusher according to claim 1, characterized in that: The multi-directional pressure plate is provided with a second deflection hole vertically aligned with the ball head rod, and a steering ball rotatably connected to a fixed plate is fixedly connected to the middle of the outer end of the multi-directional pressure plate.

3. The knife adjusting tool for a film crusher according to claim 1, characterized in that: The limiting rod is a strip columnar structure, the angle plate is installed inwardly at the middle of the outer end of the limiting rod, and the limiting rod and the angle plate are fixedly connected at the outer end of the upper surface of the support plate by the bolts.

4. The knife adjusting tool for a film crusher according to claim 3, characterized in that: The support plate, the limiting rod and the angle plate are combined to form a hollow right-angled triangular pyramid structure as a whole, and the right-angle space formed is used to accommodate the movable blade to be adjusted.

5. A method for using a knife adjusting tool for a diaphragm crusher, using the knife adjusting tool for a diaphragm crusher according to any one of claims 1 to 4, characterized in that: The steps include: Step 1: Determine the expansion angle of the moving blade according to the thickness of the plastic film to be crushed, and first adjust the expansion angle of the support plate; Step 2: Unscrew the screw rod through the hexagonal rod and pull out the positioning ring seat. At this time, the T-shaped rod on the positioning ring seat is separated from the "T"-shaped groove composed of the square long groove and the flat long groove. Then rotate the support plate to make the square long groove and the flat long groove correspond to the required matching position, and then insert the positioning ring seat into the "T"-shaped groove composed of the square long groove and the flat long groove with the T-shaped rod to complete the positioning. The hexagonal rod is used to screw the screw rod into the blind hole, so as to complete the fixation of the support plate after adjusting the angle; Step 3: Pass a pair of moving blades through the ball head rod outside the machine and place them on the support plate in a way that the middle of one side of the inner blade tip is aligned. At the same time, move the limit rod to drive the angle plate to abut against the blade side of the moving blade, and lock the bolt down to the nut on the lower side of the sliding hole, thereby completing the "radial" fixation of the moving blade on the support plate; Step 4: The entire tooling is transferred into the machine. The ball head rod is passed through the multi-directional pressure plate from bottom to top, and then the nut on the ball head rod is tightened. After the nut forms abutment limit on the moving blade, the nut on the upper side of the ball head rod finally completes the locking of the multi-directional pressure plate. At this time, the moving blade is "axially" fixed on the multi-directional pressure plate and the tool holder shaft.
