Description

Technical Field

[0001] The present invention relates to the technical field of wood processing machines, and specifically relates to a fully automatic wood processing machine. Background Technique

[0002] A wood processing machine is a mechanical device used to process, shape, and handle logs, wood, or wooden boards. With the development of technology, many wood processing machines have started to introduce numerical control technology, making the processing process more precise, automated, and efficient.

[0003] The patent with the patent announcement number CN216099431U relates to an intelligent wood processing machine, including a device base. The upper end of the device base is provided with a workbench base. The upper end of the workbench base is provided with a workbench base. The upper end surface of the workbench base is provided with four chutes. The upper end of the chute is provided with a slider. The upper end of the slider is provided with a support seat. The front end of the support seat is provided with two sleeve rods. The lower end of the sleeve rod is provided with a fixing column. The upper end of the fixing column is located inside the sleeve rod and is provided with a spring groove B. Inside the spring groove B is provided with a spring B. The fixing column and the sleeve rod are connected by the spring B. The upper end of the support seat is provided with a block seat. Through the slider, the slider can be moved according to the size of different wooden boards, improving the clamping speed of the device. The slider is fixed by a block, and the wooden board is fixed by the fixing column, improving the stability of the device.

[0004] In the above patent, it has the effect of improving the clamping speed of the device. The slider is fixed by a block, and the wooden board is fixed by the fixing column, improving the stability of the device and effectively improving the overall efficiency of wood processing. However, in actual operation, the operator needs to adjust the fixture according to the shape of the wood. Especially when clamping rod-shaped wood, the clamping effect of the flat fixture is poor, resulting in an unstable situation during the clamping process of the device. To ensure the clamping effect, the operator needs to stop the machine for adjustment, increasing the downtime. This not only affects the work efficiency but also reduces the continuity of wood processing, causing an interruption in the production rhythm. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fully automatic wood processing machine, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A fully automatic wood processing machine includes a workbench. A loading rack is fixedly installed on the top of the workbench. A driving mechanism is arranged on the surface of the loading rack. The output end of the driving mechanism is fixedly installed with a carrying plate. A support rod is fixedly installed at the bottom of the carrying plate. A rectangular groove is formed on the side of the carrying plate away from the driving mechanism. One side of the wood to be processed is placed into the inner wall of the carrying plate. The wood contacts the inner wall of the rectangular groove during movement. An arc groove is formed on the inner wall of the rectangular groove. A sliding groove is formed on the top of the workbench. The bottom of the support rod contacts the inner wall of the sliding groove. It also includes a fixing device. Among them, the fixing device includes a fixing frame, an electric push rod, a rectangular plate, two telescopic rods, a first spring, two rotating plates, a connecting plate, and a cylindrical rod. When the electric push rod is started, the output end of the electric push rod drives the rectangular plate to move downward. The movement of the rectangular plate drives the cylindrical rod to move downward. The fixing frame is fixedly installed on the top of the carrying plate. The electric push rod fixedly penetrates through the top of the fixing frame. The rectangular plate is fixedly installed at the output end of the electric push rod. The two telescopic rods slidably penetrate through the inner and outer walls of the rectangular plate. The first spring is arranged between the telescopic rod and the rectangular plate. The rectangular plate continues to move and compresses the first spring. The deformed first spring exerts a reaction force on the telescopic rod under the action of its own elasticity. The two rotating plates rotatably penetrate through the inner and outer walls of the telescopic rod. The connecting plate rotatably penetrates through the inner and outer walls of the rotating plate. The cylindrical rod is fixedly installed on the circumferential surface of the rectangular plate.

[0007] According to the above technical solution, a first anti-slip groove is formed at the bottom of the rotating plate, and a second anti-slip groove is formed at the bottom of the connecting plate. The first anti-slip groove of the rotating plate contacts the top of the wood during movement. At the same time, the second anti-slip groove of the connecting plate contacts the top of the wood during movement. A moving groove is formed on the side of the carrying plate close to the cylindrical rod. The size of the moving groove is adapted to that of the cylindrical rod. The circumferential surface of the cylindrical rod contacts the inner wall of the moving groove during movement, so that the carrying plate provides support for the moving cylindrical rod.

[0008] According to the above technical solution, a first scroll spring is arranged between the telescopic rod and the rotating plate. The rotating plate rotates towards the arc groove under the influence of the connecting plate. The rotating plate stretches the first scroll spring during rotation. The deformed first scroll spring exerts a reaction force on the telescopic rod under the action of its own elasticity. The two rotating plates are symmetrically arranged with the connecting plate as the axis of symmetry.

[0009] According to the above technical solution, it further includes a protection device and an auxiliary device; the protection device includes a fixed frame, a lifting plate, a second spring, a contact rod, a rotating shaft, an elastic sheet and a comb tooth plate. The circumferential surface of the cylindrical rod moves downward and contacts the top of the lifting plate. The movement of the cylindrical rod drives the lifting plate to move downward. The fixed frame is fixedly installed on one side of the carrying plate close to the moving groove. The lifting plate slides through the inner and outer walls of the fixed frame. The second spring is arranged between the lifting plate and the fixed frame. The contact rod is fixedly installed at the bottom of the lifting plate. The rotating shaft rotates through the inner and outer walls of the lifting plate. The elastic sheet is fixedly installed on the circumferential surface of the rotating shaft. The movement of the lifting plate drives the rotating shaft to move downward, and the movement of the rotating shaft drives the elastic sheet to move downward. The comb tooth plate is fixedly installed on the surface of the fixed frame, and a circular hole is opened at the bottom of the fixed frame.

[0010] According to the above technical solution, the circumferential surface of the contact rod contacts the inner wall of the circular hole. The movement of the lifting plate drives the contact rod to move downward. The contact rod passes through the circular hole during the movement. A first inclined surface is opened at the bottom of the contact rod. A second scroll spring is arranged between the rotating shaft and the lifting plate. The rotating shaft stretches the second scroll spring during rotation, and the second scroll spring deforms under tension. The elastic sheet is shaped like an arc.

[0011] According to the above technical solution, a clamping groove is opened on the circumferential surface of the contact rod. A second inclined surface is opened on the surface of the tooth block of the comb tooth plate. An arc surface one is opened on one side of the tooth block close to the elastic sheet. The concave surface of the elastic sheet contacts the arc surface one of the tooth block during movement. The arc surface one exerts an obstacle on the elastic sheet, and the elastic sheet rotates upward under the influence of the resistance.

[0012] According to the above technical solution, the auxiliary device includes a connecting frame, a sliding frame, a elastic sheet, a T-shaped rod, a third spring, a limiting block, a round rod and a limiting plate. The T-shaped rod stretches the third spring during movement, and the third spring deforms under tension. The connecting frame is fixedly installed on one side of the carrying plate close to the fixed frame. The sliding frame slides through the inner and outer walls of the connecting frame. The elastic sheet is arranged between the sliding frame and the connecting frame. The T-shaped rod slides through the inner and outer walls of the sliding frame. The third spring is arranged between the T-shaped rod and the sliding frame. The limiting block is fixedly installed on one side of the T-shaped rod close to the contact rod. The round rod is fixedly installed on the circumferential surface of the T-shaped rod. The limiting plate is fixedly installed on one side of the connecting frame close to the round rod. An arc surface two is opened on one side of the limiting block close to the contact rod. The first inclined surface of the contact rod moves downward and contacts the arc surface two of the limiting block. The first inclined surface moves and squeezes the arc surface two, and the limiting block moves toward the T-shaped rod under the extrusion.

[0013] According to the above technical solution, a hole groove is provided on the circumferential surface of the sliding frame, and the circumferential surface of the round rod contacts the inner wall of the hole groove. The round rod separates from the top of the limiting plate during movement, so that the limit applied by the limiting plate to the sliding frame is released, and the circumferential surface of the round rod contacts the top of the limiting plate.

[0014] The present invention provides a fully automatic wood processing machine, which has the following beneficial effects:

[0015] (1) In this fully automatic wood processing machine, the cylindrical rod contacts the inner wall of the moving groove, so that the carrying plate provides support for the moving cylindrical rod. Through the support provided by the carrying plate, the rectangular plate is more stable when squeezing the first spring, thereby improving the clamping stability and efficiency, and reducing the processing error caused by unstable clamping. At the same time, the rotating plate rotates towards the arc groove under the influence of the connecting plate, and the rotating plate contacts the circumferential surface of the rod-shaped wood during rotation. By setting the rotatable rotating plate, the rotating plate can automatically adapt to the shape of the wood, effectively reducing the downtime for adjustment, and can also automatically complete the clamping of the wood, thus greatly improving the overall efficiency of wood processing.

[0016] (2) In this fully automatic wood processing machine, the second spring exerts a reaction force on the lifting plate, and the lifting plate provides support for the cylindrical rod under the influence of the reaction force. By providing support for the cylindrical rod through the lifting plate, the stability of the clamping process is enhanced. At the same time, the vibration transmitted by the comb-shaped plate makes the contact between the rotating plate and the wood closer, thereby ensuring that the wood is more firmly held during processing. At the same time, the lifting plate provides an upward thrust for the cylindrical rod during movement. Through the thrust provided by the lifting plate, the working burden of the electric push rod is effectively reduced, and during the repeated contact between the elastic sheet and the second inclined surface, the generation of collision is avoided, thereby prolonging the service life of the elastic sheet.

[0017] (3) In this fully automatic wood processing machine, the limiting block contacts the inner wall of the card slot, so that the limiting block applies a limit to the contact rod. When used for the first time, the limiting block can automatically apply a limit to the contact rod to ensure that the operator uses it after being fully prepared, thereby improving the safety of the processing process. At the same time, the round rod contacts the bottom of the limiting plate, so that the upward reset of the sliding frame is restricted. By operating in a standard manner and quickly changing the position of the sliding frame, the operator can choose whether to enable the limiting block according to the actual situation, effectively improving the applicability of the limiting block itself.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 5, an embodiment of the present invention is: a fully automatic wood processing machine, including a workbench 1. A loading rack 2 is fixedly installed on the top of the workbench 1. A driving mechanism 3 is arranged on the surface of the loading rack 2. The output end of the driving mechanism 3 is fixedly installed with a carrying board 4. A support rod 5 is fixedly installed at the bottom of the carrying board 4. A rectangular groove is formed on one side of the carrying board 4 away from the driving mechanism 3. An arc groove is formed on the inner wall of the rectangular groove. A sliding groove is formed on the top of the workbench 1. The bottom of the support rod 5 is in contact with the inner wall of the sliding groove. It also includes a fixing device; wherein, the fixing device includes a fixing frame 6, an electric push rod 7, a rectangular plate 8, two telescopic rods 9, a first spring 10, two rotating plates 11, a connecting plate 12 and a cylindrical rod 13. The fixing frame 6 is fixedly installed on the top of the carrying board 4. The electric push rod 7 is fixedly penetrated through the top of the fixing frame 6. The rectangular plate 8 is fixedly installed at the output end of the electric push rod 7. The two telescopic rods 9 are slidably penetrated through the inner and outer walls of the rectangular plate 8. The first spring 10 is arranged between the telescopic rod 9 and the rectangular plate 8. The two rotating plates 11 are rotatably penetrated through the inner and outer walls of the telescopic rod 9. The connecting plate 12 is rotatably penetrated through the inner and outer walls of the rotating plate 11. The cylindrical rod 13 is fixedly installed on the circumferential surface of the rectangular plate 8. By setting the rotatable rotating plate 11, the rotating plate 11 can automatically adapt to the shape of the wood, effectively reducing the downtime for adjustment and also being able to complete the clamping process automatically.

[0028] A first anti-slip groove is formed at the bottom of the rotating plate 11. A second anti-slip groove is formed at the bottom of the connecting plate 12. A moving groove is formed on one side of the carrying board 4 close to the cylindrical rod 13. The size of the moving groove is adapted to that of the cylindrical rod 13. Through the support provided by the carrying board 4, the rectangular plate 8 is more stable when squeezing the first spring 10, thereby improving the clamping stability and efficiency and reducing the processing error caused by unstable clamping.

[0029] A first volute spring is arranged between the telescopic rod 9 and the rotating plate 11. The two rotating plates 11 are symmetrically arranged with the connecting plate 12 as the axis of symmetry. By setting the first volute spring, it is ensured that under normal conditions, the rotating plate 11 and the connecting plate 12 remain parallel, thereby improving the clamping stability.

[0030] During the operation of this embodiment, one side of the wood to be processed is placed inside the inner wall of the carrying plate 4. The wood contacts the inner wall of the rectangular groove during movement. The electric push rod 7 is started, and the output end of the electric push rod 7 drives the rectangular plate 8 to move downward. The movement of the rectangular plate 8 drives the cylindrical rod 13 to move downward. The circumferential surface of the cylindrical rod 13 contacts the inner wall of the moving groove during movement, so that the carrying plate 4 provides support for the moving cylindrical rod 13. At the same time, the movement of the rectangular plate 8 drives the telescopic rod 9 to move downward. The movement of the telescopic rod 9 drives the rotating plate 11 to move downward. The movement of the rotating plate 11 drives the connecting plate 12 to move downward. The first anti-slip groove of the rotating plate 11 contacts the top of the wood during movement. At the same time, the second anti-slip groove of the connecting plate 12 contacts the top of the wood during movement. The rotating plate 11 and the connecting plate 12 stop moving due to the obstruction of the wood, so that the telescopic rod 9 stops moving. The rectangular plate 8 continues to move and compresses the first spring 10. The first spring 10 deforms under the extrusion. The deformed first spring 10 exerts a reaction force on the telescopic rod 9 under the action of its own elasticity. The telescopic rod 9 exerts a downward pressure on the rotating plate 11 under the influence of the reaction force, so that the rotating plate 11 exerts a downward pressure on the top of the wood, thereby completing the clamping of the wood. The driving mechanism 3 is started, and the output end of the driving mechanism 3 drives the carrying plate 4 to move away from the loading rack 2. The movement of the carrying plate 4 drives the wood to move away from the loading rack 2. After the wood moves to the processing area, the driving mechanism 3 is turned off for processing operations. Through the support provided by the carrying plate 4, the rectangular plate 8 is more stable when compressing the first spring 10, thereby improving the clamping stability and efficiency and reducing the processing error caused by unstable clamping. When it is necessary to clamp rod-shaped wood, one side of the rod-shaped wood is placed inside the carrying plate 4. The circumferential surface of the rod-shaped wood contacts the inner wall of the arc-shaped groove during movement. The electric push rod 7 is started, and the output end of the electric push rod 7 drives the rectangular plate 8 to move downward. The rectangular plate 8 repeats the above movement to drive the rotating plate 11 to move downward. The movement of the rotating plate 11 drives the connecting plate 12 to move downward. The second anti-slip groove of the connecting plate 12 contacts the circumferential surface of the rod-shaped wood during movement. The connecting plate 12 stops moving due to the obstruction. The continuously moving rotating plate 11 rotates towards the arc-shaped groove under the influence of the connecting plate 12. The first scroll spring is stretched when the rotating plate 11 rotates. The first scroll spring deforms under the stretching. At the same time, the first anti-slip groove of the rotating plate 11 contacts the circumferential surface of the rod-shaped wood during rotation. The rotating plate 11 stops moving due to the obstruction. The rectangular plate 8 continues to move and compresses the first spring 10. The deformed first spring 10 exerts a reaction force on the telescopic rod 9, so that the rotating plate 11 exerts a pressure on the circumferential surface of the rod-shaped wood, thereby completing the clamping of the rod-shaped wood. By setting the rotatable rotating plate 11, the rotating plate 11 can automatically adapt to the shape of the wood, effectively reducing the downtime adjustment time, and can also automatically complete the clamping of the wood, thereby greatly improving the overall efficiency of wood processing.

[0031] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, a protection device and an auxiliary device are further included; the protection device includes a fixing frame 141, a lifting plate 142, a second spring 143, a contact rod 144, a rotating shaft 145, an elastic sheet 146 and a comb tooth plate 147. The fixing frame 141 is fixedly installed on the side of the carrying plate 4 close to the moving groove. The lifting plate 142 slides through the inner and outer walls of the fixing frame 141. The second spring 143 is arranged between the lifting plate 142 and the fixing frame 141. The contact rod 144 is fixedly installed at the bottom of the lifting plate 142. The rotating shaft 145 rotates through the inner and outer walls of the lifting plate 142. The elastic sheet 146 is fixedly installed on the circumferential surface of the rotating shaft 145. The comb tooth plate 147 is fixedly installed on the surface of the fixing frame 141. A circular hole is opened at the bottom of the fixing frame 141. The lifting plate 142 provides support for the cylindrical rod 13, enhancing the stability of the clamping process. At the same time, the vibration transmitted by the comb tooth plate 147 makes the contact between the rotating plate 11 and the wood closer, thus ensuring that the wood is more firmly fixed during the processing.

[0032] The circumferential surface of the contact rod 144 contacts the inner wall of the circular hole. A first inclined surface is opened at the bottom of the contact rod 144. A second scroll spring is arranged between the rotating shaft 145 and the lifting plate 142. The shape of the elastic sheet 146 is set as an arc. By setting the second scroll spring, the deformed second scroll spring can drive the rotating shaft 145 to quickly recover for collision operation.

[0033] A clamping groove is opened on the circumferential surface of the contact rod 144. A second inclined surface is opened on the surface of the tooth block of the comb tooth plate 147. An arc surface is opened on the side of the tooth block close to the elastic sheet 146. Through the thrust provided by the lifting plate 142, the working burden of the electric push rod 7 is effectively reduced. And during the repeated contact between the elastic sheet 146 and the second inclined surface, the generation of collision is avoided.

[0034] The auxiliary device includes a connecting frame 151, a sliding frame 152, an elastic piece 153, a T-shaped rod 154, a third spring 155, a limiting block 156, a round rod 157 and a limiting plate 158. The connecting frame 151 is fixedly installed on the side of the carrying plate 4 close to the fixing frame 141. The sliding frame 152 slides through the inner and outer walls of the connecting frame 151. The elastic piece 153 is arranged between the sliding frame 152 and the connecting frame 151. The T-shaped rod 154 slides through the inner and outer walls of the sliding frame 152. The third spring 155 is arranged between the T-shaped rod 154 and the sliding frame 152. The limiting block 156 is fixedly installed on the side of the T-shaped rod 154 close to the contact rod 144. The round rod 157 is fixedly installed on the circumferential surface of the T-shaped rod 154. The limiting plate 158 is fixedly installed on the side of the connecting frame 151 close to the round rod 157. An arc surface is opened on the side of the limiting block 156 close to the contact rod 144. During the initial use, the limiting block 156 can automatically apply a limit to the contact rod 144, ensuring that the operator can use it after being fully prepared, thus improving the safety of the processing process.

[0035] The circumferential surface of the sliding frame 152 is provided with a hole groove, the circumferential surface of the round rod 157 contacts the inner wall of the hole groove, and the circumferential surface of the round rod 157 contacts the top of the limiting plate 158. By operating in a standardized manner, the position of the sliding frame 152 can be quickly changed, enabling the operator to choose whether to activate the limiting block 156 according to the actual situation, effectively improving the applicability of the limiting block 156 itself.

[0036] During the operation of this embodiment, the circumferential surface of the cylindrical rod 13 moves downward and contacts the top of the lifting plate 142. The movement of the cylindrical rod 13 drives the lifting plate 142 to move downward. The movement of the lifting plate 142 drives the contact rod 144 to move downward. The contact rod 144 moves through the round hole during the movement. The lifting plate 142 squeezes the second spring 143 during the movement. The second spring 143 deforms under the squeeze. The deformed second spring 143 exerts a reaction force on the lifting plate 142. Under the influence of the reaction force, the lifting plate 142 provides support for the cylindrical rod 13. At the same time, the movement of the lifting plate 142 drives the rotating shaft 145 to move downward. The movement of the rotating shaft 145 drives the elastic piece 146 to move downward. The elastic piece 146 intermittently contacts the tooth block of the comb tooth plate 147 during the movement. When contacting, the concave surface of the elastic piece 146 contacts the arc surface of the tooth block during the movement. The arc surface exerts an obstruction on the elastic piece 146. The elastic piece 146 rotates upward under the influence of the resistance. The rotation of the elastic piece 146 drives the rotating shaft 145 to rotate upward. The rotating shaft 145 stretches the second scroll spring during the rotation. The second scroll spring deforms under the stretch. When the elastic piece 146 separates from the arc surface, the deformed scroll spring restores and drives the rotating shaft 145 to quickly reset. The rotation of the rotating shaft 145 drives the elastic piece 146 to quickly reset. The elastic piece 146 collides with the arc surface of the tooth block again during the reset process, causing the elastic piece 146 to intermittently collide with the comb tooth plate 147 to generate continuous vibration. The comb tooth plate 147 transmits the vibration to the rotating plate 11. The rotating plate 11 contacts the wood more closely under the action of the vibration. By providing support for the cylindrical rod 13 through the lifting plate 142, the smoothness of the clamping process is enhanced. At the same time, the vibration transmitted by the comb tooth plate 147 makes the contact between the rotating plate 11 and the wood closer, thus ensuring that the wood is more firmly held during processing. When the rectangular plate 8 resets upward, the cylindrical rod 13 gradually reduces the pressure exerted on the lifting plate 142 during the movement, causing the deformed second spring 143 to restore and drive the lifting plate 142 to move upward. The lifting plate 142 provides an upward thrust for the cylindrical rod 13 during the movement. At the same time, the movement of the lifting plate 142 drives the rotating shaft 145 to move upward. The movement of the rotating shaft 145 drives the elastic piece 146 to move upward. The curved surface of the elastic piece 146 contacts the second inclined surface of the comb tooth plate 147 during the movement. The moving elastic piece 146 rotates downward under the influence of the second inclined surface. The rotation of the elastic piece 146 drives the rotating shaft 145 to rotate downward, causing the second scroll spring to deform. When the elastic piece 146 separates from the second inclined surface, the second scroll spring restores and drives the rotating shaft 145 to reset. The rotation of the rotating shaft 145 drives the elastic piece 146 to reset. The reset elastic piece 146 continues to move and contact the second inclined surface. The elastic piece 146 repeats the above movement and separates from the second inclined surface. Through the thrust provided by the lifting plate 142, the working burden of the electric push rod 7 is effectively reduced. And during the repeated contact process of the elastic piece 146 and the second inclined surface, the generation of collision is avoided, thus prolonging the service life of the elastic piece 146;

[0037] During the first use, the first inclined surface of the contact rod 144 moves downward to contact the second arc surface of the limit block 156. The movement of the first inclined surface squeezes the second arc surface, and the limit block 156 moves toward the T-shaped rod 154 under the extrusion. The movement of the limit block 156 drives the T-shaped rod 154 to move away from the sliding frame 152. During the movement of the T-shaped rod 154, the third spring 155 is stretched, and the third spring 155 deforms under the stretching. When the contact rod 144 moves to the designated position, the limit block 156 separates from the circumferential surface of the contact rod 144, causing the deformed third spring 155 to recover and drive the T-shaped rod 154 to move toward the sliding frame 152. The movement of the T-shaped rod 154 drives the limit block 156 to move away from the sliding frame 152. During the movement, the limit block 156 contacts the inner wall of the card slot, so that the limit block 156 applies a limit to the contact rod 144, and the contact rod 144 stops moving under the restriction, resulting in the lifting plate 142 being unable to reset. When the operator needs to resume the movement of the lifting plate 142, the T-shaped rod 154 can be manually pulled to move the T-shaped rod 154 away from the sliding frame 152, thereby releasing the limit on the contact rod 144 and restoring the normal operation of the lifting plate 142. During the first use, the limit block 156 can automatically apply a limit to the contact rod 144 to ensure that the operator uses it after being fully prepared, thereby improving the safety of the processing process. When the limit block 156 is not needed, the T-shaped rod 154 is manually pulled to move away from the sliding frame 152. During the movement of the T-shaped rod 154, the third spring 155 is stretched, and the third spring 155 deforms under the stretching. At the same time, the movement of the T-shaped rod 154 drives the round rod 157 to move away from the sliding frame 152. During the movement, the round rod 157 separates from the top of the limiting plate 158, so that the limit applied by the limiting plate 158 to the sliding frame 152 is released. Push the T-shaped rod 154 downward. The movement of the T-shaped rod 154 drives the round rod 157 and the limit block 156 to move downward. At the same time, the movement of the T-shaped rod 154 drives the sliding frame 152 to move downward. The sliding frame 152 stretches the elastic piece 153 during the movement, and the elastic piece 153 deforms under the stretching. When the sliding frame 152 moves to the predetermined position, the T-shaped rod 154 is controlled to reset toward the sliding frame 152. The movement of the T-shaped rod 154 drives the round rod 157 to move toward the sliding frame 152. During the movement, the round rod 157 contacts the bottom of the limiting plate 158, so that the upward reset of the sliding frame 152 is restricted. At the same time, the contact rod 144 will not contact the limit block 156 during the movement. Through standardized operation, the position of the sliding frame 152 can be quickly changed, so that the operator can choose whether to enable the limit block 156 according to the actual situation, effectively improving the applicability of the limit block 156 itself.

[0038] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
