Description

Technical Field

[0001] This invention relates to the field of quartz processing technology, and in particular to a stretching processing equipment and method for quartz rods. Background Technology

[0002] In the quartz semiconductor industry, high-precision quartz rod locating pins are required. For high-precision quartz rods, such as φ0.5±0.02mm*L100mm, conventional manual machining methods are used, which mainly rely on the experience level of the workers and require a high level of skill. The thinner the quartz rod is, the more prone it is to breakage, and the outer diameter may not meet the tolerance requirements. The precision of the rods obtained by conventional manual machining methods can only reach above 0.1mm, and it cannot be guaranteed that the diameter precision meets the requirements at the same time as the length.

[0014] The present invention also provides a method for stretching a quartz rod, using the stretching equipment for quartz rods in any of the above embodiments, the method comprising:

[0015] One end of the quartz rod is held by the first clamping member, and one end of the stretching rod is held by the second clamping member;

[0019] As the stretching rod and the quartz rod rotate synchronously in the same direction, when the other end of the stretching rod is softened and connected to the other end of the quartz rod, the first moving drive assembly drives the second housing to move away from the first housing to stretch the quartz rod.

The first moving drive component drives the second housing to move away from the first housing to stretch the quartz rod. The second moving drive component drives the adjusting frame to move closer to the first housing so that the welding torch heats the quartz rod with flame along the extension direction of the quartz rod. This realizes the automated stretching process of the quartz rod, so that the quartz rod is stably stretched to the preset length and diameter requirements, which greatly reduces the occurrence of breakage. It does not rely on manual labor, saves time and effort, and improves processing efficiency and product yield. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0039] To address the problems existing in the above-mentioned technologies, embodiments of the present invention provide a stretching processing device for quartz rods, see [link to relevant documentation]. Figure 1The stretching processing equipment includes: a machine base 110, a first housing 120, a first rotary drive mechanism 130, a first clamping member 121, a second housing 140, a first moving drive assembly 150, a second rotary drive mechanism 160, a second clamping member 141, an adjusting frame 170, a second moving drive assembly 180, and a welding torch 190. The machine base 110 is hollow inside. The first housing 120 is mounted on the machine base 110 and located at one end of the machine base 110. The second housing 140 is movably and adjustablely mounted on the machine base 110 and is disposed opposite to the first housing 120. The first moving drive assembly 150 is drivenly connected to the second housing 140 and is used to drive the second housing 140 to move. The first clamping member 121 is rotatably mounted on the first housing 120 and is used to clamp one end of a quartz rod 200. The first rotary drive mechanism 130 is drivenly connected to the first clamping member 121 and is used to drive the first clamping member 121 to rotate. The second clamping member 141 is rotatably mounted on the second housing 140. The second clamping member 141 is opposite to the first clamping member 121 and is used to clamp one end of the stretching rod 300, so that the stretching rod 300 is opposite to the quartz rod 200. The second rotation drive mechanism 160 is drivably connected to the second clamping member 141 and is used to drive the second clamping member 141 to rotate. The adjusting frame 170 is movably and adjustably mounted on the machine base 110. The second movement drive assembly 180 is drivably connected to the adjusting frame 170 and is used to drive the adjusting frame 170 to move. The welding torch 190 is rotatably mounted on the adjusting frame 170 and is used to heat the quartz rod 200. Preferably, the stretching rod 300 is an auxiliary quartz rod 200.

[0040] In this embodiment, the present invention proposes an automated device for stretching quartz rods. The rotation speed of the quartz rod 200 and the stretching rod 300 can be precisely controlled by the first rotary drive mechanism 130 and the second rotary drive mechanism 160, ensuring that the quartz rod 200 and the stretching rod 300 always rotate in the same direction and synchronously during the stretching process. The moving speed of the stretching rod 300 can be precisely controlled by the first moving drive component 150, thereby controlling the stretching speed of the quartz rod 200, ensuring that the quartz rod 200 is stretched smoothly during the stretching process, and avoiding the problem of the quartz rod 200 breaking. The second moving drive component 180 can precisely control the moving speed of the adjusting frame 170, thereby controlling the moving speed of the welding torch 190. As the quartz rod 200 is stretched, the welding torch 190 gradually moves from one end of the quartz rod 200 to the other end and heats the quartz rod 200 with a flame, ensuring that the stretched part can be softened sufficiently and effectively so that the quartz rod 200 can be stretched evenly, effectively avoiding the problem of breakage due to insufficient softening.

[0041] In a preferred embodiment, see [link to previous document]. Figure 1 and Figure 2 The bottom of the second housing 140 is provided with a card holder 142, which is fitted onto the top of the machine base 110 and can move along the extension direction of the machine base 110. A first guide groove 111 is provided on one side of the machine base 110, and the setting direction of the first guide groove 111 is consistent with the extension direction of the machine base 110. The first moving drive assembly 150 includes a first gear 151, a first gear 152, a first rotating shaft 153, and a first motor 154. The first gear 151 is disposed inside the machine base 110, and the setting direction of the first gear 151 is consistent with the extension direction of the machine base 110. The first rotating shaft 153 is horizontally inserted through the first guide groove 111 and one side of the card holder 142. The first gear 152 is sleeved and fixed on the first rotating shaft 153 and meshes with the first gear 151. The first motor 154 is installed on one side of the card holder 142 and is drivenly connected to the first rotating shaft 153. The first motor 154 is used to drive the first gear 152 to move along the extension direction of the first gear 151.

[0042] In this embodiment, the first motor 154 drives the first rotating shaft 153 to rotate, thereby causing the first gear 152 on the first rotating shaft 153 to move along the extension direction of the first gear track 151, so that the first rotating shaft 153 moves within the first guide groove 111, thereby causing the card holder 142 and the second housing 140 on it to move in the extension direction of the machine base 110. This can achieve automated driving of the second housing 140 to move closer to or further away from the first housing 120, thereby precisely controlling the moving speed of the second housing 140.

[0043] In some other preferred embodiments, the first moving drive component 150 may also be a sliding module or an electric telescopic rod. Any method that can drive the card holder 142 to move is within the protection scope of this invention and is not limited here.

[0044] In one specific embodiment, see Figure 2 The machine base 110 has a second guide groove 112 on its other side, which is parallel to the first guide groove 111. The end of the first rotating shaft 153 away from the first motor 154 passes through the second guide groove 112 and extends beyond the other side of the card holder 142 to form a first rotating end. A first handle 155 is mounted on the first rotating end to rotate and adjust the first rotating shaft 153. The card holder 142 has first through holes on both sides for inserting the first rotating shaft 153. In this embodiment, by rotating the first handle 155, the first rotating shaft 153 rotates, enabling manual adjustment of the card holder 142 and its second housing 140. During manual adjustment, the first motor 154 is turned off, allowing the output shaft of the first motor 154 to rotate with the first rotating shaft 153.

[0045] In a preferred embodiment, see [link to previous document]. Figure 2 The card holder 142 is in the shape of an inverted U and includes a first connecting plate 1421 that is horizontally arranged and a second connecting plate 1422 that is vertically connected to both ends of the first connecting plate 1421. The first connecting plate 1421 and the second connecting plate 1422 are respectively slidably disposed on both sides of the machine base 110.

[0046] In one specific embodiment, see Figure 2The machine base 110 has guide rails 115 on both sides, and the direction of the guide rails 115 is consistent with the extension direction of the machine base 110. The second connecting plate 1422 has a groove 14221 corresponding to the guide rail 115, and the second connecting plate 1422 slides on the guide rail 115 through the first groove 14221. In this embodiment, the grooves 14221 on both sides and the guide rails 115 cooperate to guide the card holder 142, ensuring that the card holder 142 moves smoothly.

[0047] In a preferred embodiment, see [link to previous document]. Figure 1 and Figure 3 The bottom of the adjustment frame 170 is provided with a base 171. The base 171 is fitted onto the top of the machine platform 110 and can move along the extension direction of the machine platform 110. A first slide groove 113 is provided on one side of the machine platform 110. The setting direction of the first slide groove 113 is consistent with the extension direction of the machine platform 110. The second moving drive assembly 180 further includes a second gear rail 181, a second gear 182, a second rotating shaft 183, and a second motor 184. The second gear rail 181 is disposed within the machine base 110, and the orientation of the second gear rail 181 is consistent with the extension direction of the machine base 110. The second rotating shaft 183 is horizontally inserted through the first slide groove 113 and one side of the base 171. The second gear 182 is sleeved and fixed on the second rotating shaft 183 and meshes with the second gear rail 181. The second motor 184 is mounted on one side of the base 171 and is drivenly connected to the second rotating shaft 183. The second motor 184 is used to drive the second gear 182 to move along the extension direction of the second gear rail 181. Specifically, the second gear rail 181 and the first gear rail 151 are staggered.

[0048] In this embodiment, the second motor 184 drives the second rotating shaft 183 to rotate, thereby causing the second gear 182 on the second rotating shaft 183 to move along the extension direction of the second gear track 181, so that the second rotating shaft 183 moves within the first slide groove 113, thereby causing the base 171 and the adjustment frame 170 on it to move in the extension direction of the machine platform 110. This can realize the automatic driving of the adjustment frame 170 to move closer to or further away from the first housing 120, thereby precisely controlling the moving speed of the adjustment frame 170.

[0049] In some other preferred embodiments, the second moving drive component 180 can be a sliding module or an electric telescopic rod. Any method that can drive the card holder 142 to move is within the protection scope of this invention and is not limited here.

[0050] In one specific embodiment, see Figure 3The machine base 110 has a second slide groove 114 on its other side, which is parallel to the first slide groove 113. The end of the second rotating shaft 183 away from the second motor 184 passes through the second slide groove 114 and extends beyond the other side of the base 171 to form a second rotating end. A second handle 185 is mounted on the second rotating end for rotating and adjusting the second rotating shaft 183. The base 171 has second through holes on both sides for inserting the second rotating shaft 183. In this embodiment, rotating the second handle 185 causes the second rotating shaft 183 to rotate, enabling manual adjustment of the base 171 and the adjustment frame 170 on it. During manual adjustment, the second motor 184 is turned off, allowing the output shaft of the second motor 184 to rotate with the second rotating shaft 183.

[0051] In a preferred embodiment, see [link to previous document]. Figure 1 The stretching processing equipment further includes a telescopic member 1713 vertically mounted on the base 171. The telescopic member 1713 is telescopically adjustable and located on the side of the base 171 closest to the first housing 120. The telescopic member 1713 supports the quartz rod 200. Specifically, the telescopic member 1713 can be a cylinder or an electric telescopic rod. A graphite pad is provided at the top of the telescopic member 1713 to support the quartz rod 200. In this embodiment, during the stretching process of the quartz rod 200, the telescopic member 1713 supports the softened quartz rod 200. Because the quartz rod 200 itself has a certain rigidity, the telescopic member 1713 prevents the quartz rod 200 from falling. Since the telescopic member 1713 is mounted on the base 171, it can move with the base 171 to adjust the position of the support point.

[0052] In a preferred embodiment, see [link to previous document]. Figure 3 The base 171 is in the shape of an inverted U and includes a first fixing plate 1711 that is horizontally arranged and a second fixing plate 1712 that is vertically connected to both ends of the first fixing plate 1711. The first fixing plate 1711 and the second fixing plate 1712 are respectively slidably disposed on both sides of the machine base 110.

[0053] In one specific embodiment, see Figure 3 The second fixing plate 1712 is provided with a slot 17121 corresponding to the guide rail 115, and the second fixing plate 1712 is slidably mounted on the guide rail 115 through the first slot 17121. In this embodiment, the cooperation between the slots 17121 on both sides and the guide rail 115 guides the base 171, ensuring that the base 171 moves smoothly.

[0054] In a preferred embodiment, see [link to previous document]. Figure 1 The first rotary drive mechanism 130 includes a first drive member 131, a first driving wheel 132, a first driven wheel 133, a first transmission belt 134, and a first transmission shaft 135. The first drive member 131 is mounted on the first housing 120 and is drivenly connected to the first driving wheel 132. The first driven wheel 133 is mounted and connected to the first clamping member 121 via the first transmission shaft 135. The first transmission belt 134 is wound around the first driving wheel 132 and the first driven wheel 133. Alternatively, the second rotary drive mechanism 160 includes a second drive member 161, a second driving wheel 162, a second driven wheel 163, a second transmission belt 164, and a second transmission shaft 165. The second drive member 161 is mounted on the second housing 140 and is drivenly connected to the second driving wheel 162. The second driven wheel 163 is mounted and connected to the second clamping member 141 via the second transmission shaft 165. The second transmission belt 164 is wound around the second driving wheel 162 and the second driven wheel 163.

[0055] For details, see Figure 1 The first driving member 131 is located on the side of the first housing 120 away from the first clamping member 121, and the second driving member 161 is located on the side of the second housing 140 away from the second clamping member 141. The first driven wheel 133 is coaxially arranged with the first clamping member 121, and the second driven wheel 163 is coaxially arranged with the second clamping member 141. The first driving wheel 132, the first driven wheel 133, the first transmission belt 134, and the first transmission shaft 135 are located inside the first housing 120. The second driving wheel 162, the second driven wheel 163, the second transmission belt 164, and the second transmission shaft 165 are located on the second housing 140. The first driving member 131 and the second driving member 161 are motors.

[0056] In this embodiment, the first driving member 131 drives the first driving wheel 132 to rotate, which in turn drives the first driven wheel 133 to rotate under the transmission action of the first transmission belt 134, thereby realizing the rotation of the first clamping member 121. The second driving member 161 drives the second driving wheel 162 to rotate, which in turn drives the second driven wheel 163 to rotate under the transmission action of the second transmission belt 164, thereby realizing the rotation of the second clamping member 141. Under the drive of the first driving member 131 and the second driving member 161, the rotation speed of the first clamping member 121 and the quartz rod 200 thereon, and the rotation speed of the second clamping member 141 and the tension rod 300 thereon can be precisely controlled.

[0057] In another preferred embodiment, the first rotary drive mechanism 130 and the second rotary drive mechanism 160 can be motors, that is, the motors can be used to directly drive the first clamping member 121 and the second clamping member 141 to rotate.

The clamping member 179 is installed at the end of the second sleeve 178 near the first housing 120, and the clamping member 179 is used to hold the welding torch 190.

[0059] In this embodiment, the height of the welding torch 190 can be adjusted by adjusting the installation position of the first clamp 173 on the vertical pipe 172; the position of the welding torch 190 in the longitudinal direction can be adjusted by adjusting the installation position of the second clamp 175 on the first sleeve 176; and the position of the welding torch 190 in the lateral direction can be adjusted by adjusting the installation position of the third clamp 177 on the second sleeve 178, thereby achieving position adjustment of the welding torch 190 in three-dimensional space. The welding torch 190 can be rotated horizontally by adjusting the second clamp 175, rotated horizontally by adjusting the first sleeve 176, rotated left-right by adjusting the first sleeve 176, and rotated forward-backward by adjusting the second sleeve 178, thereby achieving angle adjustment of the welding torch 190 in three-dimensional space.

[0060] In one specific embodiment, see Figure 5The first clamp 173 consists of a C-shaped kit 1731, end plates 1732 formed at both ends of the kit 1731, and locking members 1733 fastened to the two end plates 1732. The two end plates 1732 are arranged in parallel, and the locking members 1733 are installed through the two end plates 1732. By adjusting the locking members 1733, the distance between the two end plates 1732 can be adjusted so that the kit 1731 can adapt to the size of the installed pipe fitting, thereby achieving an effective clamping and fixing effect. Specifically, the locking member 1733 can be a first bolt or a first screw, etc. The second clamp 175 and the third clamp 177 have the same structure as the first clamp 173, and will not be described again here.

The first clamping portion 1791 is clamped to one side of the welding torch 190 through the first mounting groove, and the second clamping portion 1792 is clamped to the other side of the welding torch 190 through the second mounting groove. The pair of fasteners 1793 are inserted and installed on the first clamping portion 1791 and the second clamping portion 1792, located on both sides of the welding torch 190, thus clamping the first clamping portion 1791 and the second clamping portion 1792 onto the welding torch 190. Preferably, the fasteners 1793 can be a second bolt or a second screw, etc.

[0062] In one specific embodiment, see Figure 4 A first hinge portion 1734 is formed on the first clamp 173, and a second hinge portion 1751 is formed on the second clamp 175 corresponding to the first hinge portion 1734. The side of the first hinge portion 1734 and the second hinge portion 1751 that is close to each other is a horizontal plane to facilitate horizontal rotation adjustment of the second clamp 175. An adjusting member 174 is vertically installed on the first hinge portion 1734 and the second hinge portion 1751 to lock and fix the first hinge portion 1734 and the second hinge portion 1751. By releasing the lock on the first hinge portion 1734 and the second hinge portion 1751, the first hinge portion 1734 and the second hinge portion 1751 can rotate relative to each other. Specifically, the adjusting member 174 can be a third bolt or a third screw, etc.

[0063] Preferably, the first clamping member 121 and the second clamping member 141 are three-jaw chucks, and the first clamping member 121 and the second clamping member 141 are coaxially arranged so that the first clamping member 121 and the second clamping member 141 can rotate coaxially.

[0064] For a better option, see [link to previous section]. Figure 1 The first gear 151 is provided with first limiting blocks 1511 at both ends to restrict the first gear 152 from slipping off the first gear 151, and the second gear 181 is provided with second limiting blocks 1811 at both ends to restrict the second gear 182 from slipping off the second gear 181.

[0065] Preferably, the outer wall of the first sleeve 176 is provided with a first anti-slip part, the outer wall of the second sleeve 178 is provided with a second anti-slip part, and the outer wall of the vertical pipe 172 is provided with a third anti-slip part to increase friction. The first anti-slip part, the second anti-slip part, and the third anti-slip part are a plurality of protrusions arranged at intervals, and the protrusions may be strip-shaped or block-shaped.

[0066] In a preferred embodiment, the stretching processing equipment further includes a control console connected to the first rotary drive mechanism 130, the first motion drive assembly 150, the second rotary drive mechanism 160, and the second motion drive assembly 180.

[0067] The present invention also provides a method for stretching a quartz rod, using the stretching equipment for quartz rods in any of the above embodiments, the method comprising:

[0068] One end of the quartz rod 200 is held by the first clamping member 121, and one end of the stretching rod 300 is held by the second clamping member 141.

[0069] The first moving drive assembly 150 is activated, and the first moving drive assembly 150 drives the second housing 140 to move closer to the first housing 120 until the other end of the stretching rod 300 abuts against the other end of the quartz rod 200.

[0070] The second moving drive assembly 180 is activated, which drives the adjusting frame 170 to move toward the point where the tension rod 300 and the quartz rod 200 abut, until the nozzle of the welding torch 190 is aligned with the point where the tension rod 300 and the quartz rod 200 abut.

[0071] The first rotary drive mechanism 130 and the second rotary drive mechanism 160 are activated. The first rotary drive mechanism 130 and the second rotary drive mechanism 160 drive the first clamping member 121 and the second clamping member 141 to rotate synchronously in the same direction, so that the quartz rod 200 and the tension rod 300 rotate synchronously in the same direction. At the same time, the welding torch 190 sprays flames at the point where the tension rod 300 and the quartz rod 200 collide.

[0072] As the stretching rod 300 and the quartz rod 200 rotate synchronously in the same direction, when the other end of the stretching rod 300 is softened and connected to the other end of the quartz rod 200, the first moving drive assembly 150 drives the second housing 140 to move away from the first housing 120 to stretch the quartz rod 200. At the same time, the second moving drive assembly 180 drives the adjusting frame 170 to move closer to the first housing 120 so that the welding torch 190 heats the quartz rod 200 with a flame along the extension direction of the quartz rod 200 until a quartz rod 200 that meets the preset length and diameter requirements is produced.

[0073] Preferably, during the stretching of the quartz rod 200, the rotational speeds of the first clamping member 121 and the second clamping member 141 are in the range of 10-50 r / min; the moving speed of the second housing 140 is in the range of 0.03-0.3 m / s; and the moving speed of the welding torch 190 is in the range of 0.002-0.02 m / s. In this embodiment, by controlling the rotational speed, it can be ensured that the quartz rod 200 is subjected to uniform and appropriate force during the stretching process, thereby avoiding breakage or deformation. Compared with the problems caused by unstable or excessively high rotational speeds that may exist in traditional machining, this rotational speed control is more precise and reliable. By precisely controlling the moving speed, the smoothness of the stretching process and the uniformity of heating can be ensured. Compared with the problems caused by inconsistent or excessively fast manual operation speeds that may occur in traditional machining, this automated speed control can significantly improve processing quality and efficiency, and greatly reduce the scrap rate due to improper operation or unreasonable equipment parameter settings. This not only saves material costs but also improves overall production efficiency.

[0074] In a preferred embodiment, after the quartz rod 200 is processed to meet the preset length and diameter requirements, the method further includes cutting the connection between the quartz rod 200 and the tension rod 300.

[0075] This invention utilizes a first clamping member 121 and a second clamping member 141 to clamp the quartz rod 200 and the tension rod 300 respectively, ensuring their stability during processing. Driven by the first rotary drive mechanism 130 and the second rotary drive mechanism 160, the quartz rod 200 and the tension rod 300 rotate synchronously in the same direction, which helps the welding torch 190 to uniformly heat the outer wall of the quartz rod 200 and maintains uniform stress on the quartz rod 200 during stretching, thereby reducing the risk of breakage. When the contact point between the tension rod 300 and the quartz rod 200 reaches a softened state, the first moving drive assembly 150 drives the second housing 140 to move away from the first housing 120, thereby stretching the quartz rod 200. During this process, the second moving drive assembly 180 simultaneously drives the adjusting frame 170 to move closer to the first housing 120, so that the welding torch 190 continuously heats the quartz rod 200 along its extension direction. This continuous heating helps maintain the softened state of the quartz rod 200, making it easier to stretch and less prone to breakage. Automated equipment enables high-precision and highly consistent processing, significantly improving the quality and performance of quartz rods 200 and reducing product variations caused by human factors. Automated processing methods greatly increase processing efficiency, reducing the time and cost of manual operation. Simultaneously, optimized processes and precise control reduce scrap rates and material waste, further lowering production costs. Traditional machining methods heavily rely on worker experience and skills, while this method, through precise equipment and programmed control, significantly reduces the impact of human factors, making the processing more stable and reliable.

[0076] In one embodiment, the second housing 140 includes a first housing body 1401, a second housing body 1402, and a pressure measuring device 1403, such as Figure 7 As shown, specifically, the first shell body 1401 and the second shell body 1402 are connected by a pressure measuring device 1403. The first shell body 1401 is disposed opposite to the first shell 120. The second clamping member 141 is rotatably mounted on the side of the first shell body 1401 away from the pressure measuring device 1403. The second driving member 161 is mounted on the first shell body 1401. The first shell body 1401 is separated from the card holder 142, and the second shell body 1402 is connected to the card holder 142. The card holder 142 and the second driving member 161 do not contact each other. During operation, the pressure measuring device 1403 (which can be understood as a tension sensor) is electrically connected to the processor and display screen on the control console. The pressure measuring device 1403 is used to monitor the tension of the stretched quartz rod 200 and collect the tension signal of the quartz rod 200. The processor receives the tension signal, processes it, and transmits it to the display screen for display, thereby monitoring the tension of the quartz rod 200 during the stretching process in real time.

[0077] In another embodiment, an anti-breakage device 40 is provided between the pressure measuring device 1403 and the second shell body 1402. The anti-breakage device 40 is configured such that when the pressure measuring device 1403 detects that the tensile force is greater than or about to exceed a preset threshold (the preset threshold can be understood as the tensile force that just causes the quartz rod 200 to break), the anti-breakage device 40 has the ability to extend and retract. By extending and retracting a certain amount, it avoids the tensile force that is greater than or about to exceed the preset threshold from being directly applied to the quartz rod 200, thereby avoiding the situation where the quartz rod 200 breaks due to excessive tensile force. When the pressure measuring device 1403 detects that the tensile force is less than or equal to the preset threshold, the anti-breakage device 40 does not have the ability to extend and retract, so that the tensile force is directly applied to the quartz rod 200 for the stretching process.

[0078] Specifically, such as Figure 8 As shown, the anti-breakage device 40 includes a telescopic rod 401, a support cylinder 402, and a support spring 403. The telescopic rod 401 is movably inserted into the support cylinder 402. The ends of the telescopic rod 401 and the support cylinder 402 that are far apart from each other are respectively connected to the pressure measuring device 1403 and the second shell body 1402. The support spring 403 is wound around the telescopic rod 401, and the two ends of the support spring 403 are respectively fixedly connected to the side wall of the telescopic rod 401 and the outer side wall of the support cylinder 402.

[0079] Preferably, in order to achieve a better limiting effect, so that the telescopic rod 401 can only move horizontally to the left relative to the support cylinder 402, both the cylinder cavity of the support cylinder 402 and the telescopic rod 401 are set as rectangular structures in this invention.

[0080] Preferably, the anti-breakage device 40 further includes an iron locking rod 404, a locking groove 405, an electromagnet 406, and a return spring 407. The iron locking rod 404 is movably inserted into the support cylinder 402. The locking groove 405 is formed on the telescopic rod 401. The iron locking rod 404 is movably inserted into the locking groove 405. The return spring 407 is wound around the iron locking rod 404, and its two ends are fixedly connected to the side wall of the iron locking rod 404 and the outer side wall of the support cylinder 402, respectively. An electromagnet 406 is provided directly above the iron locking rod 404 and is fixedly provided on the outer side wall of the support cylinder 402.

[0081] Preferably, the number of locking slots 405 is set to a plurality of them, and the plurality of locking slots 405 are arranged in a straight line on the same horizontal plane. The distance between two adjacent locking slots 405 is negligible. To ensure that the iron locking rod 404 can always enter the locking slot 405, in one embodiment, the lower end of the iron locking rod 404 is provided with a conical structure. It should be understood that, as long as the iron locking rod 404 can enter the locking slot 405, the lower end of the iron locking rod 404 can be set to other shapes, not limited to a conical structure.

[0082] During operation, when the pressure measuring device 1403 detects that the tension is greater than or about to exceed the preset threshold, the processor receives the signal and controls the electromagnet 406 to generate magnetism. The magnetism attracts the iron locking rod 404 to move upward, causing the iron locking rod 404 to move outside the locking groove 405. At this time, the telescopic rod 401 can move to the right relative to the support cylinder 402 under the action of tension, thus enabling the anti-breakage device 40 to have a telescopic function. When the pressure measuring device 1403 detects that the tension is less than or equal to the preset threshold, the processor controls the electromagnet 406 to be de-energized. At this time, the electromagnet 406 loses its magnetism and, under the action of the return spring 407, causes the iron locking rod 404 to return downward and enter another locking groove 405, thereby realizing the re-locking of the telescopic rod 401 and the support cylinder 402.

[0083] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as set forth in the claims.
