Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of testing primary side current, in particular to a fixed adjusting tool for testing primary side current of products. BACKGROUND

[0002] In the research and production of power electronic devices, industrial control modules and other products, the test of primary side current is one of the core links for evaluating the electrical performance, safety and reliability of the products. As a key parameter of the input side of the main circuit of the product, the primary side current directly reflects the power consumption, load matching state and potential fault risk (such as overload, short circuit, etc.) of the device, and its measurement accuracy and stability are decisive for the quality control of the product.

[0003] At present, in the product testing link, fixed tools are widely used for clamping and positioning of products, so as to ensure the relative stability of the testing process. However, most of the current tools cannot adjust the relative position of the copper bar and the product, so that when the size of the copper bar and the specification of the product change, the magnetic field will change, which will affect the test results. SUMMARY

[0004] To solve the above technical problems, the present application provides a fixed adjusting tool for testing primary side current of products, comprising a plurality of angle irons, a plurality of angle irons are fixedly connected with a profile on the outer wall, further comprising:

[0005] An adjusting mechanism is fixedly connected with the outer wall of the profile, and the adjusting mechanism is used for adjusting the test position to facilitate the test;

[0006] A clamping mechanism is fixedly connected with the outer wall of the adjusting mechanism, and the clamping mechanism is used for clamping the product to facilitate the test of the product;

[0007] A limiting mechanism is slidingly connected with the inner wall of the clamping mechanism, and the limiting mechanism is used for limiting the operation of the clamping mechanism;

[0008] The outer wall of the profile is fixedly connected with a slide rail, the outer wall of the slide rail is slidingly connected with two slide blocks, and the outer wall of the two slide blocks is threadedly connected with a plurality of butterfly bolts.

[0009] In use, first, a plurality of angle irons are fixed at the required position, then the profile is fixed on the outer wall of the plurality of angle irons, further, the plurality of butterfly bolts at the two slide blocks are loosened, and because of the loss of the butterfly bolts, the two slide blocks can slide freely on the slide rail, at this time, the two slide blocks are moved to the approximate appropriate position, then any butterfly bolt on the two slide blocks is tightened to lock the two slide blocks from moving;

[0010] Preferably, the adjusting mechanism comprises:

[0011] The outer wall of the fixing assembly is fixedly connected with the outer wall of the sliding block;

[0012] The outer wall of the adjusting assembly is threadedly connected with the outer wall of the fixing assembly.

[0013] Preferably, the clamping mechanism comprises:

[0014] The outer wall of the sliding assembly is fixedly connected with the outer wall of the adjusting assembly;

[0015] The outer wall of the clamping assembly is slidingly connected with the inner wall of the sliding assembly.

[0016] Preferably, the limiting mechanism comprises:

[0017] The outer wall of the triggering assembly is slidingly connected with the inner wall of the sliding assembly;

[0018] The outer wall of the limiting assembly is slidingly connected with the inner wall of the sliding assembly.

[0019] Preferably, the fixing assembly comprises a fixing block fixedly connected with the outer wall of the sliding block, a contact electrode fixedly connected with the inner wall of the fixing block, and a bolt screwedly connected with the inner wall of the contact electrode.

[0020] The copper bar is passed through the middle of the clamping mechanism, and at the same time, the copper bar is tightly attached to the outer walls of the two fixing blocks and the contact electrode. Then the position of the copper bar is adjusted so that the central axis of the copper bar is located in the middle of the two sliding blocks. At this time, the adjusting bolts on both sides are tightened so that the adjusting bolts tightly attach the copper bar to the outer walls of the contact electrode and the fixing blocks, thereby completing the fixing of the copper bar. At this time, the fixing screw of the sliding plate is loosened again, the position of the sliding plate is moved to conform to the test position, and after the position is adjusted, the fixing screw of the sliding plate is tightened to complete the fixing.

[0021] Preferably, the adjusting assembly comprises an adjusting bolt threadedly connected with the inner wall of the fixing block, a copper bar threadedly clamped and fixedly connected with the adjusting bolt, and a sliding plate slidingly connected with the outer wall of the profile.

[0022] Further, the fixing screw on the sliding plate is loosened so that the sliding plate can slide on the side wall of the profile. At this time, the position of the sliding plate is moved so that the sliding plate is located in the approximate position between the two sliding blocks. Then the screw on the sliding plate is tightened to fix the position of the sliding plate.

[0023] Preferably, the sliding assembly comprises a fixing plate fixedly connected with the outer wall of the sliding plate, two positioning pins fixedly connected with the inner wall of the fixing plate, a lead screw rotatably connected with the inner wall of the fixing plate, and two clamping blocks slidingly connected with the inner wall of the fixing plate. The outer wall of the two positioning pins is slidingly connected with a product sample.

[0024] The inner walls of the two clamping blocks are engaged with the screw rod.

[0025] Then, the two positioning pins are inserted into the positioning holes on the fixing plate, and then the product sample to be tested is placed on the side wall of the fixing plate, and the two positioning pins clamp and position the product sample. At this time, the position of the product sample needs to be adjusted. At this time, the screw rod is screwed to start rotating, and the screw rod rotates while the two clamping blocks engaged with the outer wall of the screw rod move in opposite directions. With the continuous rotation of the screw rod, the two clamping blocks gradually approach the inner wall of the product sample.

[0026] Preferably, the clamping assembly comprises a sliding rod slidingly connected to the inner wall of the clamping block, a plurality of tooth grooves are formed on the outer wall of the sliding rod, a limiting rotation block is rotatably connected to the outer wall of the clamping block, a reset spring is sleeved on the outer wall of the clamping block, and a limiting spring is fixedly connected to the outer wall of the sliding rod.

[0027] The two ends of the reset spring are fixedly connected to the outer wall of the clamping block, the central axis of the reset spring is rotatably connected to the inner wall of the limiting rotation block and penetrates to the other end, and the outer wall of the end of the limiting spring away from the sliding rod is fixedly connected to the inner wall of the clamping block.

[0028] When the screw is rotated, the two clamping blocks are moved away from each other, and the two limiting rotating blocks in the clamping blocks are tightly attached to the outer wall of the gear groove under the action of the reset spring, and the sliding rod has a tendency to move close to the clamping block under the action of the limiting spring, but the limiting rotating block is tightly attached to the outer wall of the gear groove under the action of the reset spring, so that the limiting rotating block limits the tendency of the sliding rod to move to the clamping block under the action of the limiting spring. When the sliding rod is pulled away from the clamping block, the limiting spring stores elastic potential energy, and the limiting rotating block is tightly attached to the outer wall of the gear groove under the action of the reset spring, but the outer wall of the limiting rotating block cannot be clamped in the outer wall of the gear groove when the sliding rod is pulled away from the clamping block, and can only be tightly attached to the surface of the gear groove, so that the sliding rod cannot be limited. When the sliding rod is moved to a position greater than the width of the product sample, the sliding rod is stopped, and the sliding rod moves close to the clamping block under the action of the limiting spring, but the limiting rotating block is clamped in the outer wall of the gear groove under the action of the reset spring, so that the sliding rod cannot move. At the same time, the end of the limiting rotating block away from the gear groove is higher than the clamping block, and the two ends of the clamping block gradually approach the product sample, and the limiting rotating block contacts the product sample first, and gradually approaches the gear groove on the side close to the product sample, and gradually moves away from the gear groove on the other side. When the outer surface of the clamping block contacts the inner wall of the product sample, the surface of the limiting rotating block is away from the gear groove, so that the limiting rotating block cannot limit the sliding rod, and the sliding rod starts to move towards the clamping block under the action of the limiting spring. At this time, the sliding rod starts to move towards the clamping block with the product sample under the action of the limiting spring, and the two clamping blocks are tightly attached to the product sample, so that the center of the product sample is the same as the center of the clamping block, and the position of the product sample is in the center of the clamping mechanism, so that the position of the product sample does not need to be adjusted again.

[0029] Preferably, the triggering assembly comprises a sliding block slidingly connected to the inner wall of the clamping block, and the outer wall of the sliding rod is fixedly connected with two hook connecting rods, and the outer wall of the sliding block is fixedly connected with an arc-shaped block.

[0030] When the sliding rod fixes the product sample on the outer wall of the clamping block, the sliding block is forced to move close to the clamping block when the sliding rod moves towards the clamping block;

[0031] Preferably, the limiting assembly comprises a square slot opened in the inner wall of the clamping block, and a limiting rod is slidingly connected to the inner wall of the square slot, and two hook connecting rod slots are opened in the inner wall of the clamping block.

[0032] When the arc-shaped block at the sliding block moves to the limiting rod, the arc-shaped block extrudes the limiting rod, so that the limiting rod moves along the square notch to the lead screw, so that the limiting rod is clamped at the gap of the lead screw, so that the lead screw cannot continue to rotate, thereby the clamping block cannot apply pressure to the product sample, and the limiting rod also clamps the lead screw, so that the lead screw cannot be loosened, when the test of the product sample is completed, the sliding rod needs to be pulled away from the clamping block, at this time, the hook connecting rod fixed on the sliding rod drives the sliding block away from the clamping block, and the limiting rod loses the limitation of the arc-shaped block, when the lead screw is twisted in the opposite direction to make the clamping block not clamp the product sample, the reverse rotation of the lead screw makes the limiting rod away from the lead screw, so that the limiting rod does not limit the lead screw.

[0033] The present application has the following beneficial effects:

[0034] (1) The present application is to solve the problem of adjusting the position of the product and the copper bar during the test of the product original edge current, and the adjusting mechanism is provided, first, a plurality of angle irons are fixed at the required position, then the profile is fixed at the outer wall of the plurality of angle irons, further, the butterfly bolts at the two sliding blocks are twisted to loosen them, and because the butterfly bolts are lost, the two sliding blocks can slide freely on the slide rail, at this time, the two sliding blocks are moved to the approximate suitable position, then any butterfly bolt on the two sliding blocks is twisted to lock it, so that the two sliding blocks cannot move; further, the fixing screws on the sliding plate are loosened, so that the sliding plate can slide on the side wall of the profile, at this time, the position of the sliding plate is moved, so that the sliding plate is located at the approximate position between the two sliding blocks, then the screws on the sliding plate are tightened to fix the position of the sliding plate; the copper bar is inserted through the middle of the clamping mechanism, and the copper bar is tightly attached to the outer wall of the contact electrode and the fixed block, then the position of the copper bar is adjusted, so that the central axis of the copper bar is located between the two sliding blocks, at this time, the adjusting screws on both sides are twisted, so that the adjusting screws tightly attach the copper bar to the outer wall of the contact electrode and the fixed block, thereby the copper bar is fixed, at this time, the fixing screws of the sliding plate are loosened again, the position of the sliding plate is moved, so as to facilitate the test, after the position is adjusted, the fixing screws of the sliding plate are tightened to fix them;

[0035] (2) The present application is to solve the problem that the product sample needs to meet different specifications when clamping due to different specifications of the product. A sliding assembly is provided. When the clamping blocks at both ends gradually approach the product sample, the limiting rotating block first contacts the product sample. As the clamping blocks continue to move under the action of the lead screw, the limiting rotating block on the side close to the product sample gradually approaches the gear slot, and the other end of the limiting rotating block gradually moves away from the gear slot. When the outer surface of the clamping block contacts the inner wall of the product sample, the surface of the limiting rotating block is away from the gear slot at this time, so that the limiting rotating block cannot limit the sliding rod, and then under the action of the limiting spring, the sliding rod starts to move towards the clamping block. At this time, under the action of the limiting spring, the sliding rod starts to move towards the clamping block with the product sample until it is tightly attached to the clamping block. Under the joint action of these components, the clamping mechanism can adapt to different specifications of the product sample, increasing the adaptability of the device.

[0036] (3) The present application utilizes the operating mechanism of the above-mentioned mechanism and is provided with a clamping assembly. The lead screw is twisted to start rotating, and at the same time, the two clamping blocks meshing at the outer wall of the lead screw are driven to move in opposite directions. As the lead screw continues to rotate, the two clamping blocks gradually approach the inner wall of the product sample. Because the curvature of the outer surface of the clamping block is the same as the curvature of the inner wall of the product sample, after the two clamping blocks tightly attach to the product sample, the center positions of the inner wall of the product sample and the outer wall of the clamping block are the same. Therefore, the position of the product sample is located at the center of the entire clamping mechanism, so that it is not necessary to adjust the position of the product sample again.

[0037] (4) The present application is to solve the problem that the product sample clamping is loose due to vibration of other equipment and other factors, and to reduce the deformation of the product sample caused by excessive clamping force of the clamping assembly. A limiting mechanism is provided. When the sliding rod fixes the product sample at the outer wall of the clamping block, the sliding block is forced to move towards the clamping block when the sliding rod moves towards the clamping block. When the arc-shaped block located at the sliding block moves to the limiting rod along with the sliding block, the arc-shaped block extrudes the limiting rod to make the limiting rod move along the square slot towards the lead screw. The limiting rod is clamped in the gap of the lead screw, so that the lead screw cannot continue to rotate, and the clamping block cannot apply pressure to the product sample. At the same time, the limiting rod also clamps the lead screw, so that the lead screw cannot be loosened. When the test on the product sample is completed, the sliding rod needs to be pulled away from the clamping block. At this time, the hook-shaped connecting rod fixed on the sliding rod drives the sliding block away from the clamping block, and the limiting rod loses the limitation of the arc-shaped block. When the clamping block no longer clamps the product sample by twisting the lead screw in the opposite direction, the reverse rotation of the lead screw makes the limiting rod move away from the lead screw, so that the limiting rod cannot limit the lead screw.

[0071] Further, the fixing screw on the sliding plate 123 is loosened, so that the sliding plate 123 can slide at the side wall of the section bar 14, at this time, the position of the sliding plate 123 is moved so that the sliding plate 123 is located at the approximate position between the two sliding blocks 112, then the screw on the sliding plate 123 is tightened to fix the position of the sliding plate 123;

[0072] The sliding assembly 21 comprises a fixed plate 211 fixedly connected at the outer wall of the sliding plate 123, two positioning pins 212 fixedly connected at the inner wall of the fixed plate 211, a lead screw 213 rotatably connected at the inner wall of the fixed plate 211, two clamping blocks 214 slidably connected at the inner wall of the fixed plate 211, and a product sample 215 slidably connected at the outer wall of the two positioning pins 212.

[0073] The inner wall of the two clamping blocks 214 is meshingly connected with the lead screw 213.

[0074] Then, the two positioning pins 212 are inserted into the positioning holes on the fixed plate 211, and then the product sample 215 to be tested is placed at the side wall of the fixed plate 211, at the same time, the two positioning pins 212 will clamp and position the product sample 215, but the position of the product sample 215 needs to be adjusted at this time, at this time, the lead screw 213 is screwed to make the lead screw 213 start to rotate, and at the same time that the lead screw 213 rotates, the two clamping blocks 214 meshingly connected at the outer wall thereof are driven to move in opposite directions, and as the lead screw 213 continues to rotate, the two clamping blocks 214 gradually approach the inner wall of the product sample 215;

[0075] Embodiment two, please refer to Figure 2 - Figure 11 The present application is a kind of fixed adjustment tool that can test product original edge current, on the basis of example one, the clamping assembly 22 comprises a sliding rod 221 slidably connected at the inner wall of the clamping block 214, a plurality of tooth grooves 222 are formed at the outer wall of the sliding rod 221, a limiting rotation block 223 is rotatably connected at the outer wall of the clamping block 214, a return spring 224 is sleeved on the outer wall of the clamping block 214, and a limiting spring 225 is fixedly connected at the outer wall of the sliding rod 221.

[0076] Two ends of the reset spring 224 are fixedly connected at the outer wall of the clamping block 214, the middle axis of the reset spring 224 is rotatably connected at the inner wall of the limiting rotation block 223 and penetrates to the other end, and the outer wall of the limiting spring 225 away from the one end of the sliding rod 221 is fixedly connected with the inner wall of the clamping block 214.

[0077] When the two clamping blocks 214 are not moved, the two limiting rotation blocks 223 in the clamping blocks 214 will be tightly attached to the outer wall close to the tooth groove 222 under the action of the reset spring 224, and the sliding rod 221 will have a tendency to move close to the clamping block 214 under the action of the limiting spring 225, but the limiting rotation block 223 will be tightly attached to the outer wall of the tooth groove 222 under the action of the reset spring 224, so that the limiting rotation block 223 limits the tendency of the sliding rod 221 to move to the clamping block 214 under the action of the limiting spring 225. After the sliding rod 221 is pulled away from the clamping block 214, the limiting spring 225 will store corresponding elastic potential energy, and the limiting rotation block 223 will be tightly attached to the outer wall of the tooth groove 222 under the action of the reset spring 224, but since the outer wall of the limiting rotation block 223 cannot be clamped in the outer wall of the tooth groove 222 when the sliding rod 221 moves away from the clamping block 214, it can only be tightly attached to the surface of the tooth groove 222 and cannot be limited, when the sliding rod 221 moves to a position greater than the width of the product sample 215, the pulling of the sliding rod 221 is stopped, at this time the sliding rod 221 will move close to the clamping block 214 under the action of the limiting spring 225, but since the reset spring 224 will clamp the limiting rotation block 223 in the outer wall of the tooth groove 222 at this time, the sliding rod 221 cannot move, and the end of the limiting rotation block 223 away from the tooth groove 222 will be higher than the clamping block 214, when the two clamping blocks 214 gradually approach the product sample 215, the limiting rotation block 223 will first contact the product sample 215, and as the clamping block 214 continues to move under the action of the lead screw 213, the side of the limiting rotation block 223 close to the product sample 215 will gradually approach the tooth groove 222, and the other end of the limiting rotation block 223 will gradually move away from the tooth groove 222, when the outer surface of the clamping block 214 contacts the inner wall of the product sample 215, the surface of the limiting rotation block 223 will be away from the tooth groove 222 at this time, so that the limiting rotation block 223 cannot limit the sliding rod 221, and then under the action of the limiting spring 225, the sliding rod 221 will start to move towards the clamping block 214, at this time, the sliding rod 221 will start to move towards the clamping block 214 with the product sample 215 under the action of the limiting spring 225, and since the curvature of the outer surface of the clamping block 214 is the same as the curvature of the inner wall of the product sample 215, the two clamping blocks 214 will make the center position of the inner wall of the product sample 215 the same as the center position of the outer wall of the clamping block 214 after being tightly attached to the product sample 215, so that the position of the product sample 215 is located at the center of the entire clamping mechanism 2, so that the position of the product sample 215 does not need to be adjusted again;

[0078] The triggering component 31 comprises a sliding block 311 connected to the inner wall of the clamping block 214, two hook connecting rods 312 are fixedly connected to the outer wall of the sliding rod 221, and an arc-shaped block 313 is fixedly connected to the outer wall of the sliding block 311.

[0079] When the sliding rod 221 fixes the product sample 215 at the outer wall of the clamping block 214, the sliding block 311 is forced to move close to the clamping block 214 when the sliding rod 221 moves towards the clamping block 214;

[0080] The limiting component 32 comprises a square notch 321 formed in the inner wall of the clamping block 214, a limiting rod 322 is slidingly connected to the inner wall of the square notch 321, and two hook connecting rod notches 323 are formed in the inner wall of the clamping block 214.

[0081] When the arc-shaped block 313 at the sliding block 311 moves to the limiting rod 322, the limiting rod 322 is pressed to move along the square notch 321 towards the lead screw 213, so that the limiting rod 322 is clamped in the gap of the lead screw 213, so that the lead screw 213 cannot continue to rotate, thereby the clamping block 214 cannot apply pressure to the product sample 215, and the limiting rod 322 also clamps the lead screw 213, so that the lead screw 213 cannot be loosened. When the test on the product sample 215 is completed, the sliding rod 221 needs to be pulled away from the clamping block 214, at this time, the hook connecting rod 312 fixed on the sliding rod 221 drives the sliding block 311 away from the clamping block 214, and the limiting rod 322 loses the limitation of the arc-shaped block 313. When the lead screw 213 is twisted in the opposite direction to make the clamping block 214 no longer clamp the product sample 215, the reverse rotation of the lead screw 213 makes the limiting rod 322 away from the lead screw 213, so that the limiting rod 322 does not limit the lead screw 213.

[0082] One specific application of the embodiment is that: in use, first, a plurality of angle irons 13 are fixed at the required positions, then the profiled bar 14 is fixed at the outer wall of the plurality of angle irons 13, further, the butterfly bolts 113 at the two sliding blocks 112 are twisted to be loosened, and because the butterfly bolts 113 are loosened, the two sliding blocks 112 can slide freely on the slide rails 111, at this time, the two sliding blocks 112 are moved to be located at the approximate appropriate positions, then any butterfly bolt 113 on the two sliding blocks 112 is twisted to be locked, so that the two sliding blocks 112 cannot move; further, the fixing screws on the sliding plate 123 are loosened, so that the sliding plate 123 can slide on the side wall of the profiled bar 14, at this time, the position of the sliding plate 123 is moved to be located at the approximate position between the two sliding blocks 112, then the screws on the sliding plate 123 are tightened to fix the position of the sliding plate 123;

[0083] Then, two positioning pins 212 are inserted into the positioning holes on the fixing plate 211, and then the product sample 215 to be tested is placed at the side wall of the fixing plate 211, at the same time, the two positioning pins 212 will clamp and position the product sample 215, but the position of the product sample 215 needs to be adjusted at this time, at this time, the screw rod 213 is screwed to make the screw rod 213 start to rotate, and at the same time, the screw rod 213 rotates to drive the two clamping blocks 214 engaged on the outer wall of the screw rod 213 to start to move in opposite directions, and with the continuous rotation of the screw rod 213, the two clamping blocks 214 gradually approach the inner wall of the product sample 215;

[0084] When the two clamping blocks 214 are not moved, the two limiting rotation blocks 223 in the clamping blocks 214 will be tightly attached to the outer wall close to the tooth groove 222 under the action of the reset spring 224, and the sliding rod 221 will have a tendency to move close to the clamping block 214 under the action of the limiting spring 225, but the limiting rotation block 223 will be tightly attached to the outer wall of the tooth groove 222 under the action of the reset spring 224, so that the limiting rotation block 223 limits the tendency of the sliding rod 221 to move to the clamping block 214 under the action of the limiting spring 225. After the sliding rod 221 is pulled away from the clamping block 214, the limiting spring 225 will store corresponding elastic potential energy, and the limiting rotation block 223 will be tightly attached to the outer wall of the tooth groove 222 under the action of the reset spring 224, but since the outer wall of the limiting rotation block 223 cannot be clamped in the outer wall of the tooth groove 222 when the sliding rod 221 moves away from the clamping block 214, it can only be tightly attached to the surface of the tooth groove 222 and cannot be limited, when the sliding rod 221 moves to a position greater than the width of the product sample 215, the pulling of the sliding rod 221 is stopped, at this time the sliding rod 221 will move close to the clamping block 214 under the action of the limiting spring 225, but since the reset spring 224 will clamp the limiting rotation block 223 in the outer wall of the tooth groove 222 at this time, the sliding rod 221 cannot move, and the end of the limiting rotation block 223 away from the tooth groove 222 will be higher than the clamping block 214, when the two clamping blocks 214 gradually approach the product sample 215, the limiting rotation block 223 will first contact the product sample 215, and as the clamping block 214 continues to move under the action of the lead screw 213, the side of the limiting rotation block 223 close to the product sample 215 will gradually approach the tooth groove 222, and the other end of the limiting rotation block 223 will gradually move away from the tooth groove 222, when the outer surface of the clamping block 214 contacts the inner wall of the product sample 215, the surface of the limiting rotation block 223 will be away from the tooth groove 222 at this time, so that the limiting rotation block 223 cannot limit the sliding rod 221, and then under the action of the limiting spring 225, the sliding rod 221 will start to move towards the clamping block 214, at this time, the sliding rod 221 will start to move towards the clamping block 214 with the product sample 215 under the action of the limiting spring 225, and since the curvature of the outer surface of the clamping block 214 is the same as the curvature of the inner wall of the product sample 215, the two clamping blocks 214 will make the center position of the inner wall of the product sample 215 the same as the center position of the outer wall of the clamping block 214 after being tightly attached to the product sample 215, so that the position of the product sample 215 is located at the center of the entire clamping mechanism 2, so that the position of the product sample 215 does not need to be adjusted again.

[0085] When the product sample 215 is fixed, the copper bar 122 is passed through the middle of the product sample 215, and the copper bar 122 is tightly fixed at the outer wall of the contact electrode 115 and the fixing block 114. Then, the position of the copper bar 122 is adjusted so that the central axis of the copper bar 122 is located in the middle of the two sliding blocks 112. At this time, the adjusting bolts 121 on both sides are tightened so that the adjusting bolts 121 tightly fix the copper bar 122 at the outer wall of the contact electrode 115 and the fixing block 114. Thus, the copper bar 122 is fixed. At this time, the fixing screws of the sliding plate 123 are loosened again, and the position of the sliding plate 123 is moved so as to facilitate the test of the product sample 215. After the position is adjusted, the fixing screws of the sliding plate 123 are tightened to fix the sliding plate 123.

[0086] When the sliding rod 221 fixes the product sample 215 at the outer wall of the clamping block 214, the sliding block 311 is forced to move close to the clamping block 214 when the sliding rod 221 moves towards the clamping block 214. When the arc-shaped block 313 located at the sliding block 311 moves to the limiting rod 322 along with the sliding block 311, the limiting rod 322 is pressed to move along the square notch 321 towards the lead screw 213. The limiting rod 322 is clamped in the gap of the lead screw 213, so that the lead screw 213 cannot continue to rotate, thereby preventing the clamping block 214 from applying pressure to the product sample 215. At the same time, the limiting rod 322 also clamps the lead screw 213, so that the lead screw 213 cannot be loosened. After the test of the product sample 215 is completed, the sliding rod 221 needs to be pulled away from the clamping block 214. At this time, the hook-shaped connecting rod 312 fixed on the sliding rod 221 drives the sliding block 311 away from the clamping block 214, and the limiting rod 322 loses the limitation of the arc-shaped block 313. When the lead screw 213 is twisted in the opposite direction to prevent the clamping block 214 from clamping the product sample 215, the reverse rotation of the lead screw 213 drives the limiting rod 322 away from the lead screw 213, thereby preventing the limiting rod 322 from limiting the lead screw 213.
