Description

Technical Field

[0001] This invention relates to the field of gate removal equipment technology, specifically a gate removal machine for castings. Background Technology

[0002] Casting gate removal machines are used to break and separate casting gates, runners, and risers. Common equipment types include hydraulic expansion clamp type gate and riser separators, pneumatic impact type gate removal machines (pneumatic hammers), and mechanical impact type gate removal machines. The core purpose is to replace traditional manual hammering, pneumatic chisel and other methods to achieve high-efficiency, high-quality and low-damage gate removal.

[0003] When using hydraulic expansion clamps to remove gates, the wedge head of the clamp is usually inserted into the gap of the gate in the casting, and then the clamp is driven to open. The opening force is used to pry off the gate and remove it. However, the gap size of the gate in some castings is small. When the operator is working, after inserting the clamp into the gap, the clamp needs to be opened slightly to widen the gap, and then the clamp is retracted. After readjusting the position, it is often necessary to insert and open the clamp repeatedly to remove the gate, which affects the processing efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a casting gate removal machine, including a housing and a hydraulic cylinder, wherein the left side of the hydraulic cylinder and the right side of the housing are fixedly connected, a handle is fixedly connected to the top of the housing, and a plurality of wedges are provided on the left side of the housing, and the machine also includes:

[0005] The main structure is installed on the inner wall of the housing. The housing includes a sliding groove formed on the inner wall of the housing, and several stepped plates are fixedly connected to the inner wall of the sliding groove.

[0006] The reciprocating mechanism is installed on the inner wall of the sliding groove, and the inner wall of the sliding groove is provided with several flow dividers.

[0007] The pushing mechanism is installed on the inner wall of the housing, and the inner wall of the housing is slidably connected to the pushing plate.

[0008] The machine is equipped with two wedges, two step plates, and two flow dividers. When in use, the operator holds the handle and adjusts the position of the machine housing and the wedges so that the wedges are aligned with the gap between the gate and the casting. Then, the wedges are inserted into the gap, and the main mechanism causes the wedges to open the gate.

[0009] Preferably, the main structure also includes:

[0010] A connecting component is installed on the inner wall of the sliding groove;

[0011] The separation component is installed on the inner wall of the wedge.

[0012] Preferably, the reciprocating mechanism also includes:

[0013] A reset assembly is installed on the inner wall of the sliding groove;

[0014] The grading component is installed on the inner wall of the flow divider.

[0015] Preferably, the pushing mechanism further includes:

[0016] The extrusion assembly is mounted on top of the wedge.

[0017] Preferably, the connecting assembly includes a piston cylinder disposed on the inner wall of the sliding groove, wherein the side of the piston cylinder away from the wedge is fixedly connected to the side of the hydraulic cylinder output end near the wedge.

[0018] A piston rod is slidably connected to the inner wall of the piston cylinder, and hydraulic oil is installed inside the piston cylinder. The top of the outer wall of the piston cylinder is fixedly connected to the bottom of the push plate.

[0019] Preferably, the separation assembly includes inclined blocks slidably connected to the inner walls of a plurality of wedges, wherein the side of the inclined block near the piston cylinder is fixedly connected to the side of the piston rod near the wedge.

[0020] The inner wall of the sliding groove is slidably connected with several connecting plates, and the side of the connecting plates away from the hydraulic cylinder is fixedly connected to the side of the wedges close to the piston cylinder.

[0021] The system includes two connecting plates. After the wedge head is inserted into the gap of the gate, the hydraulic cylinder extends and pushes the piston cylinder to move.

[0022] Preferably, the reset assembly includes a plurality of sliding frames slidably connected to the inner wall of the sliding groove, and the outer wall of the plurality of sliding frames near the wedge head is slidably connected to the inner wall of the housing;

[0023] Several connecting plates are fixedly connected to spring rods on the side away from the outer wall of the piston cylinder. The outer walls of several spring rods are slidably connected to the inner wall of the sliding frame. The outer walls of several flow dividers are connected through the inner wall of the piston cylinder.

[0024] There are two sliding frames and two spring rods.

[0025] Preferably, the grading assembly includes a piston rod 2 slidably connected to the inner wall of the diverter cylinder, and a plurality of piston rod 2 inner walls are rotatably connected with balls, and the outer walls of the plurality of balls are in contact with the side of the plurality of stepped plates near the piston cylinder.

[0026] There are two piston rods and two ball bearings. At this time, the hydraulic oil in the piston cylinder is blocked by the piston rods and the ball bearings are blocked by the step plate. Therefore, the hydraulic oil cannot push the piston rods to move and cannot flow. The piston cylinder will push the piston rods to move through the hydraulic oil. The piston rods will drive the inclined block to move. The inclined surface of the inclined block will squeeze the inclined surface of the wedge, causing the two wedges to move away from each other and open up the wedges, thereby widening the gap of the gate. The wedges will drive the connecting plate and the spring rod to move, causing the spring rod to be compressed and accumulate rebound force.

[0027] As the piston cylinder moves, it simultaneously drives the flow divider, piston rod two, and balls to move. As the balls continue to move, they will move to the next step of the stepped plate. At this point, the obstruction to piston rod two disappears, the spring force stored in the spring rod is released, and the wedges are reset, causing the two wedges to move closer to each other. The wedges will press against the inclined block in the opposite direction, and the inclined block will drive piston rod one to squeeze hydraulic oil into the flow divider, pushing piston rod two and balls to move until the balls are in contact with the next step of the stepped plate again, which will block the flow of hydraulic oil again and reset the wedges.

[0028] After the wedge head resets, it will separate from the gate. The piston cylinder continues to move, which will push the piston rod and the inclined block to move. Since the wedge head is not blocked after separating from the gate, the inclined block will push the wedge head to move, which will drive the connecting plate, spring rod and sliding frame to move away from the hydraulic cylinder until the wedge head contacts the gate and casting again. The wedge head will be blocked and cannot move further. The inclined block continues to move, which will squeeze the two wedge heads to separate from each other again, and widen the gap of the gate again until the piston rod and the ball move to the next step of the step plate. The above steps will be repeated. As the piston cylinder continues to move, the gate will be gradually widened and finally removed.

[0029] By applying the above structure, the gate can be removed simply by extending the hydraulic cylinder, thereby reducing the number of steps required by the operator and effectively preventing the problem of needing to repeatedly insert the gate to remove it due to its small gap, thus significantly improving processing efficiency.

[0030] Preferably, the extrusion assembly includes a connecting rod fixedly connected to the top of the wedge, and a plurality of connecting rods are fixedly connected to an angled plate on the side near the extrusion plate;

[0031] There are two connecting rods and two angled plates. When the piston cylinder pushes the inclined block to squeeze the two wedges away from each other and open the gate, the wedges will drive the connecting rods and angled plates to move. The angled plates will move towards the push plate. When the piston cylinder moves, it will drive the push plate to move. As the piston cylinder continues to move, when the piston cylinder drives the piston rod and the ball to move to the next step of the stepped plate, the obstruction to the hydraulic oil will disappear, and the inclined surface of the angled plate will fit with the inclined surface of the push plate.

[0032] At this point, the wedge and the inclined block are blocked by the gate, which has a large pushing resistance and is difficult to move. The piston rod one will remain stationary, and the piston cylinder will continue to move, which will squeeze the hydraulic oil into the manifold and push the piston rod two to move.

[0033] The piston cylinder also drives the push plate to move, causing the inclined surface of the push plate to press the angled plate towards the piston cylinder, which in turn drives the connecting rod and the wedge to move, causing the wedge to initially separate from the gate. Subsequently, the rebound force of the spring rod is quickly released, allowing the wedge to quickly reset, which in turn drives the connecting rod and the angled plate to reset. This effectively prevents the problem of large static friction between the two during the process of the wedge opening the gate, which would make it difficult for the wedge to reset, and ensures that the wedge and the gate are fully separated.

[0034] The present invention has the following beneficial effects:

[0035] (1) In this invention, when removing the gate, the operator holds the handle and adjusts the position of the machine housing and the wedge head so that the wedge head is aligned with the gap between the gate and the casting. Then, the wedge head is inserted into the gap, and the hydraulic cylinder is activated to extend. Through the connecting component and the separating component, the gap of the gate is widened. Then, through the reset component and the grading component, the gap of the gate is automatically widened multiple times, gradually enlarging the gate. Finally, the gate is removed. The gate can be removed simply by activating the hydraulic cylinder to extend, thereby reducing the number of steps for the operator and effectively preventing the problem of needing to repeatedly insert the wedge head to remove the gate due to the small gap of the gate, thus significantly improving the processing efficiency.

[0036] (2) In this invention, the two wedges are separated and opened by the multi-level steps of the stepped plate. After each opening, the wedges will reset and prepare for the next opening, so as to realize the multiple small-scale, gradual extrusion of the gate to expand the gap. The gate will gradually accumulate damage and eventually break in multiple cycles, so that the force on the gate is smaller each time, thereby reducing the stress transmitted to the casting body in a single operation, reducing the force on the casting body, effectively preventing the casting from being subjected to excessive force due to excessive single extrusion force when removing the gate, which will increase the risk of micro-cracks in the casting, and ensuring the integrity of the casting after the gate is removed.

[0037] (3) In this invention, when the piston cylinder pushes the inclined block to squeeze the two wedges away from each other and open the gate, the wedges will drive the connecting rod and the inclined plate to move. The inclined plate will move towards the pushing plate. When the piston cylinder moves, the wedges and the gate are initially separated by the squeezing assembly. Then the spring rod will release the rebound force quickly, allowing the wedges to quickly reset and drive the connecting rod and the inclined plate to reset. As shown in the figure, this effectively prevents the problem that the static friction between the two is large during the process of the wedges opening the gate, which makes it difficult for the wedges to reset, and ensures that the wedges and the gate are fully separated.

[0038] (4) In this invention, since the inner diameter of the manifold is larger than that of the piston cylinder, and there are two manifolds, as shown in the figure, the hydraulic oil in the piston cylinder flows into the manifold and pushes the piston rod two to move. The distance that the piston rod two moves is relatively short, so that when the step plate has multiple steps, the volume of the step plate is also small, reducing the space occupied by the step plate. When the gate is expanded by multiple small-batch, gradual extrusion, the volume of the machine casing is also small and the weight is light, making it easy for operators to operate.

Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example 1, please refer to Figures 1-8 This invention relates to a casting gate removal machine, comprising a housing 13 and a hydraulic cylinder 14. The left side of the hydraulic cylinder 14 is fixedly connected to the right side of the housing 13. A handle 15 is fixedly connected to the top of the housing 13. Several wedges 16 are provided on the left side of the housing 13. The machine also includes:

[0055] The main body 1 is installed on the inner wall of the housing 13. The housing 13 includes a sliding groove 101 formed on the inner wall of the housing 13. Several stepped plates 102 are fixedly connected to the inner wall of the sliding groove 101.

[0056] The reciprocating mechanism 2 is installed on the inner wall of the sliding groove 101, and the inner wall of the sliding groove 101 is provided with a plurality of flow dividers 201.

[0057] The pushing mechanism 3 is installed on the inner wall of the housing 13, and the inner wall of the housing 13 is slidably connected to the pushing plate 301.

[0058] There are two wedges 16, two step plates 102, and two flow dividers 201. When in use, the operator holds the handle 15 and adjusts the position of the housing 13 and the wedges 16 so that the wedges 16 are aligned with the gap between the gate and the casting. Then the wedges 16 are inserted into the gap, and the main mechanism 1 makes the wedges 16 open the gate.

[0059] Main body 1 also includes:

[0060] Connection component 11 is installed on the inner wall of sliding groove 101;

[0061] Separation component 12 is installed on the inner wall of wedge head 16.

[0062] Reciprocating mechanism 2 also includes:

[0063] Reset component 21 is installed on the inner wall of sliding groove 101;

[0064] The grading component 22 is installed on the inner wall of the flow divider 201.

[0065] The pushing mechanism 3 also includes:

[0066] The extrusion assembly 31 is mounted on top of the wedge 16.

[0067] Example 2, please refer to Figures 3-11 The present invention is a casting gate knocking machine. Based on the first embodiment, the connecting assembly 11 includes a piston cylinder 111 disposed on the inner wall of the sliding groove 101. The side of the piston cylinder 111 away from the wedge 16 is fixedly connected to the side of the output end of the hydraulic cylinder 14 near the wedge 16.

[0068] The piston cylinder 111 has a piston rod 112 slidably connected to its inner wall. The piston cylinder 111 is filled with hydraulic oil. The top of the outer wall of the piston cylinder 111 is fixedly connected to the bottom of the push plate 301.

[0069] The separation assembly 12 includes an inclined block 121 that is slidably connected to the inner wall of a plurality of wedges 16. The side of the inclined block 121 near the piston cylinder 111 is fixedly connected to the side of the piston rod 112 near the wedge 16.

[0070] The inner wall of the sliding groove 101 is slidably connected with several connecting plates 122. The side of the several connecting plates 122 away from the hydraulic cylinder 14 is fixedly connected to the side of several wedges 16 near the piston cylinder 111.

[0071] Two connecting plates 122 are provided. After the wedge 16 is inserted into the gap of the gate, the hydraulic cylinder 14 is activated to extend and push the piston cylinder 111 to move. The piston cylinder 111 pushes the piston rod 112 to move through the hydraulic oil. The piston rod 112 will drive the inclined block 121 to move. The inclined surface of the inclined block 121 will squeeze the inclined surface of the wedge 16, causing the two wedges 16 to move away from each other and open up the wedges 16, thereby widening the gap of the gate.

[0072] The reset assembly 21 includes a plurality of sliding frames 211 that are slidably connected to the inner wall of the sliding groove 101. The outer wall of the plurality of sliding frames 211 near the wedge head 16 is slidably connected to the inner wall of the housing 13.

[0073] A number of connecting plates 122 are fixedly connected to spring rods 212 on the side away from the outer wall of piston cylinder 111. The outer walls of the spring rods 212 are slidably connected to the inner wall of sliding frame 211. The outer walls of the flow dividers 201 are connected through to the inner wall of piston cylinder 111.

[0074] There are two sliding frames 211 and two spring rods 212. The movement of the wedge head 16 will drive the connecting plate 122 and the spring rods 212 to move, so that the spring rods 212 are compressed and accumulate rebound force.

[0075] The grading assembly 22 includes a piston rod 221 that is slidably connected to the inner wall of the diverter 201. The inner walls of several piston rods 221 are rotatably connected to balls 222. The outer walls of several balls 222 are in contact with the side of several stepped plates 102 near the piston cylinder 111.

[0076] There are two piston rods 221 and two balls 222. Since the hydraulic oil in the piston cylinder 111 is blocked by the piston rods 221 and the balls 222 are blocked by the step plate 102, the hydraulic oil cannot push the piston rods 221 to move and the hydraulic oil cannot flow. Therefore, the piston cylinder 111 can push the piston rods 112 to move through the hydraulic oil.

[0077] As the piston cylinder 111 moves, it synchronously drives the flow divider 201, piston rod 221, and ball bearings 222 to move. With the continuous movement of the ball bearings 222, they will move to the next step position on the stepped plate 102, such as... Figure 6 As shown, at this time, the obstruction of piston rod 221 disappears, the rebound force accumulated by spring rod 212 is released, and the wedge head 16 is reset, so that the two wedge heads 16 move closer to each other. The wedge head 16 will press the inclined block 121 in the opposite direction. The inclined block 121 will drive piston rod 112 to squeeze hydraulic oil into the distributor cylinder 201, pushing piston rod 221 and ball 222 to move until the ball 222 is in contact with the next step of the step plate 102 again, which will block the flow of hydraulic oil again and reset the wedge head 16.

[0078] After the wedge 16 is reset, it will separate from the gate. The piston cylinder 111 continues to move, which will push the piston rod 112 and the inclined block 121 to move. Since the wedge 16 is not blocked after it is separated from the gate, the inclined block 121 will push the wedge 16 to move, which will drive the connecting plate 122, the spring rod 212 and the sliding frame 211 to move away from the hydraulic cylinder 14 until the wedge 16 contacts the gate and the casting again. The wedge 16 will be blocked and cannot move further. The inclined block 121 continues to move, which will squeeze the two wedges 16 to separate from each other again, and widen the gap of the gate again until the piston rod 221 and the ball 222 move to the next step of the step plate 102. The above steps will be repeated. As the piston cylinder 111 continues to move, the gate will be gradually widened and finally removed.

[0079] With the application of the above structure, the gate can be removed simply by activating the hydraulic cylinder 14 to extend, thereby reducing the number of steps required by the operator and effectively preventing the problem of needing to repeatedly insert the cylinder to remove the gate due to its small size, thus significantly improving processing efficiency.

[0080] The extrusion assembly 31 includes a connecting rod 311 fixedly connected to the top of the wedge 16, and a bevel plate 312 is fixedly connected to one side of each connecting rod 311 near the push plate 301.

[0081] Two connecting rods 311 and two angled plates 312 are provided. When the piston cylinder 111 pushes the inclined block 121 to squeeze the two wedges 16 away from each other and open the gate, the wedges 16 will drive the connecting rods 311 and the angled plates 312 to move. The angled plates 312 will move towards the push plate 301. When the piston cylinder 111 moves, it will drive the push plate 301 to move. As the piston cylinder 111 continues to move, when the piston cylinder 111 drives the piston rod 221 and the ball 222 to move to the next step position of the stepped plate 102, the obstruction to the hydraulic oil disappears, and the inclined surface of the angled plate 312 will fit against the inclined surface of the push plate 301. Figure 10 As shown;

[0082] At this time, the wedge 16 and the inclined block 121 are blocked by the gate, and have a large pushing resistance and are difficult to move. The piston rod 112 will remain stationary, and the piston cylinder 111 will continue to move, squeezing the hydraulic oil into the distributor cylinder 201 and pushing the piston rod 221 to move.

[0083] The piston cylinder 111 also drives the push plate 301 to move, causing the inclined surface of the push plate 301 to press the angled plate 312 towards the piston cylinder 111, which in turn drives the connecting rod 311 and the wedge head 16 to move, causing the wedge head 16 to initially separate from the gate. Subsequently, the rebound force of the spring rod 212 will be quickly released, allowing the wedge head 16 to quickly return to its original position, which in turn drives the connecting rod 311 and the angled plate 312 to return to their original positions. Figure 11As shown, this effectively prevents the problem of large static friction between the wedge head 16 and the gate during the process of the wedge head 16 opening the gate, which would make it difficult for the wedge head 16 to return to its original position, and ensures that the wedge head 16 and the gate are fully separated.

[0084] The number of the above structures is not limited. Those skilled in the art can freely set them according to actual needs, as long as the above structures are installed at the connection positions of the corresponding structures.

[0085] A specific application of this embodiment is as follows: When removing the gate, the operator holds the handle 15 and adjusts the position of the housing 13 and the wedge 16 so that the wedge 16 is aligned with the gap between the gate and the casting. Then, the wedge 16 is inserted into the gap, and the hydraulic cylinder 14 is activated to extend and push the piston cylinder 111 to move. At this time, the hydraulic oil in the piston cylinder 111 is blocked by the piston rod 221 and the ball 222 is blocked by the step plate 102. Therefore, the hydraulic oil cannot push the piston rod 221 to move, and the hydraulic oil cannot flow. The piston cylinder 111 will push the piston rod 112 to move through the hydraulic oil. The piston rod 112 will drive the inclined block 121 to move. The inclined surface of the inclined block 121 will squeeze the inclined surface of the wedge 16, so that the two wedges 16 are far apart and the wedges 16 are spread apart, thereby widening the gap of the gate. The wedge 16 will drive the connecting plate 122 and the spring rod 212 to move, so that the spring rod 212 is compressed and accumulates rebound force.

[0086] As the piston cylinder 111 moves, it synchronously drives the flow divider 201, piston rod 221, and ball bearings 222 to move. With the continuous movement of the ball bearings 222, they will move to the next step position on the stepped plate 102, such as... Figure 6 As shown, at this time, the obstruction of piston rod 221 disappears, the rebound force accumulated by spring rod 212 is released, and the wedge head 16 is reset, so that the two wedge heads 16 move closer to each other. The wedge head 16 will press the inclined block 121 in the opposite direction. The inclined block 121 will drive piston rod 112 to squeeze hydraulic oil into the distributor cylinder 201, pushing piston rod 221 and ball 222 to move until the ball 222 is in contact with the next step of the step plate 102 again, which will block the flow of hydraulic oil again and reset the wedge head 16.

[0087] After the wedge 16 is reset, it will separate from the gate. The piston cylinder 111 continues to move, which will push the piston rod 112 and the inclined block 121 to move. Since the wedge 16 is not blocked after it is separated from the gate, the inclined block 121 will push the wedge 16 to move, which will drive the connecting plate 122, the spring rod 212 and the sliding frame 211 to move away from the hydraulic cylinder 14 until the wedge 16 contacts the gate and the casting again. The wedge 16 will be blocked and cannot move further. The inclined block 121 continues to move, which will squeeze the two wedges 16 to separate from each other again, and widen the gap of the gate again until the piston rod 221 and the ball 222 move to the next step of the step plate 102. The above steps will be repeated. As the piston cylinder 111 continues to move, the gate will be gradually widened and finally removed.

[0088] With the application of the above structure, the gate can be removed simply by activating the hydraulic cylinder 14 to extend, thereby reducing the number of steps for operators and effectively preventing the problem of needing to repeatedly insert the gate to remove it due to its small gap, thus significantly improving processing efficiency.

[0089] The multi-step design of the stepped plate 102 allows the two wedges 16 to separate and open the gate. After each expansion, the wedges 16 will reset and prepare for the next expansion, thus achieving multiple small-scale, gradual compression of the gate to enlarge the gap. This allows the gate to gradually accumulate damage and eventually break through multiple cycles, resulting in smaller forces on the gate each time. This reduces the stress transmitted to the casting body in a single operation, thereby reducing the force on the casting body. It effectively prevents the casting from being subjected to excessive force due to excessive single extrusion force when removing the gate, which would increase the risk of micro-cracks in the casting. This ensures the integrity of the casting after the gate is removed.

[0090] When the piston cylinder 111 pushes the inclined block 121 to squeeze the two wedges 16 away from each other and open the gate, the wedges 16 will drive the connecting rod 311 and the inclined plate 312 to move. The inclined plate 312 will move towards the push plate 301. When the piston cylinder 111 moves, it will drive the push plate 301 to move. As the piston cylinder 111 continues to move, when the piston cylinder 111 drives the piston rod 221 and the ball 222 to move to the next step position of the stepped plate 102, the obstruction to the hydraulic oil disappears, and the inclined surface of the inclined plate 312 will fit against the inclined surface of the push plate 301. Figure 10 As shown;

[0091] At this time, the wedge 16 and the inclined block 121 are blocked by the gate, and have a large pushing resistance and are difficult to move. The piston rod 112 will remain stationary, and the piston cylinder 111 will continue to move, squeezing the hydraulic oil into the distributor cylinder 201 and pushing the piston rod 221 to move.

[0092] The piston cylinder 111 also drives the push plate 301 to move, causing the inclined surface of the push plate 301 to press the angled plate 312 towards the piston cylinder 111, which in turn drives the connecting rod 311 and the wedge head 16 to move, causing the wedge head 16 to initially separate from the gate. Subsequently, the rebound force of the spring rod 212 will be quickly released, allowing the wedge head 16 to quickly return to its original position, which in turn drives the connecting rod 311 and the angled plate 312 to return to their original positions. Figure 11 As shown, this effectively prevents the large static friction between the wedge head 16 and the gate during the process of the wedge head 16 opening the gate, which would make it difficult for the wedge head 16 to return to its original position, thus ensuring that the wedge head 16 and the gate are fully separated.

[0093] Because the inner diameter of the flow divider 201 is larger than the inner diameter of the piston cylinder 111, and there are two flow dividers 201, such as Figure 5 As shown, when the hydraulic oil in the piston cylinder 111 flows into the distributor cylinder 201 and pushes the piston rod 221 to move, the piston rod 221 moves a short distance, so that when the step plate 102 has multiple steps, the volume of the step plate 102 is also small, reducing the space occupied by the step plate 102. When the gate is expanded by multiple small-batch, gradual extrusion, the volume of the machine housing 13 is also small and the weight is light, making it easier for operators to operate.

[0094] After the gate is removed, the hydraulic cylinder 14 retracts, causing the piston cylinder 111, piston rod 112, and inclined block 121 to reset. The inclined block 121 pushes the connecting plate 122 towards the hydraulic cylinder 14, and the connecting plate 122 simultaneously resets the wedge head 16. During the reset process, both wedge heads 16 are in a closed state, thus the inclined plate 312 and the push plate 301 are separated. Figure 9 As shown, the wedge 16 can be successfully reset.
