At this time, the extrusion block 207 on the side of the traction slider 204 will break away from the abutment on the top of the fixed tooth block 208. The contact column 209 and the fixed tooth block 208 are pulled by the second elastic member 210, and the end of the fixed tooth block 208 is disengaged from the rack 202 on the same side, so that the user can freely slide the rack 202 to adjust the measuring width. After the adjustment is completed, the release rotary block 201 is released, and the squeezing block 207 pushes the fixed tooth block 208 to re-engage with the rack 202. At this time, due to the obstruction of the squeezing block 207, the fixed tooth block 208 will maintain the current position of the rack 202, thereby maintaining the measuring length of the current device, which is convenient for parallelism detection of cylinder guide rails of different widths.

Since the middle part of the second bevel gear 405 is threadedly connected to the driving screw 403, and the measuring seat 401 is slidingly connected to the rack 202, the extended length of the measuring seat 401 can be further adjusted as the driving screw 403 rotates, thereby improving the accuracy of the test.

[0024] Specifically, Figure 1 , Figure 2 , Figure 4, Figure 6 As shown, the support structure 3 includes a support frame 301, the side of the telescopic sleeve 1 is slidably connected with the support frame 301, a third elastic member 303 is fixedly connected between the support frame 301 and the telescopic sleeve 1, a locking rod 304 is slidably connected to the inner side of the telescopic sleeve 1, a fourth elastic member 305 is fixedly connected between the locking rod 304 and the telescopic sleeve 1, one end of the locking rod 304 is in conflict with the fixed tooth block 208, a plurality of locking grooves 306 are provided on the side of the support frame 301, one end of the locking rod 304 away from the fixed tooth block 208 is engaged with the support frame 301 through the locking groove 306, and a plurality of first pulleys 302 are rotatably connected to the bottom side of the support frame 301; A support frame 301 is provided on the side of the telescopic sleeve 1, and a third elastic member 303 is connected between the support frame 301 and the telescopic sleeve 1. When the user rotates the release rotary block 201, the fixed tooth block 208 slides. At this time, the locking rod 304 is disengaged from the support frame 301 under the traction of the fourth elastic member 305, so that the support frame 301 slides out to support the middle part of the telescopic sleeve 1. After the user completes the telescopic length adjustment of the rack 202, the release rotary block 201 is released. At this time, the tooth block position is restored, and then the locking rod 304 is pushed to re-engage with the locking groove 306 on the side of the support frame 301, thereby fixing the current support state of the support frame 301 and improving the stability of the support.

[0025] Specifically, Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, the indicating structure 5 comprises an inspection plate 502, the bottom side of the measuring seat 401 is provided with an inspection plate 502, the bottom side of the measuring seat 401 is parallelly fixedly connected with two guide rods 504, the inspection plate 502 is slidably connected to the measuring seat 401 through the guide rods 504, the two sides of the inspection plate 502 are respectively fixedly connected to the measuring seat 401 with fifth elastic members 505, the inner side of the inspection plate 502 is rotatably connected with a rotating sleeve 503, the inner side of the measuring seat 401 is rotatably connected with an indicating rod 501, the bottom end of the indicating rod 501 is slidably connected with the rotating sleeve 503, the distance between the indicating rod 501 and the rotating sleeve 503 is less than the length of the indicating rod 501 in the measuring seat 401, the indicating rod 501 is in a "T"-shaped structure, and the top end of the indicating rod 501 is slidably connected with the measuring seat 401; After completing the adjustment of the measuring distance of the device, a detection plate 502 slides on the bottom side of the measuring seat 401 at both ends, and the detection plate 502 slides along the guide rod 504. At the same time, a fifth elastic member 505 is fixed between the two sides of the detection plate 502 and the measuring seat 401, which is used to keep the detection plate 502 located in the middle position of the measuring seat 401. When the parallelism of the cylinder guide rail is measured by the detection plate 502, if the detection plate 502 is offset, the rotating sleeve 503 on the inner side of the detection plate 502 will drive the indicator rod 501 to rotate. The length of the indicator rod 501 on the inner side of the measuring seat 401 is relatively large, so that the smaller offset at the bottom end of the indicator rod 501 will be displayed as a larger offset on the top side, thereby facilitating the operator to observe the parallelism and offset of the cylinder guide rail and improving the measurement accuracy.

[0026] Specifically, Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.11 , Fig.12 As shown, the reversing structure 6 includes a reversing shaft 601, the bottom side of the detection plate 502 is rotatably connected with the reversing shaft 601, the side of the reversing shaft 601 is rotatably connected with a plurality of second pulleys 603, a first positioning groove 602 is provided in the middle of the reversing shaft 601, a release block 604 is slidably connected in the middle of the detection plate 502, a sixth elastic member 605 is fixedly connected between the release block 604 and the detection plate 502, an end of the release block 604 is engaged with the reversing shaft 601 through the first positioning groove 602, a plurality of second positioning grooves 606 are respectively provided at both ends of the reversing shaft 601, a positioning column 607 is slidably connected to the inner side of the detection plate 502, a seventh elastic member 608 is fixedly connected between the positioning column 607 and the detection plate 502, the bottom end of the positioning column 607 is a hemispherical structure, and the spherical end of the positioning column 607 is in conflict with the reversing shaft 601 through the second positioning groove 606; After the adjustment of the device is completed, a plurality of pulleys are provided on the bottom side of the detection plate 502. The accuracy of the test can be ensured by making the pulleys fit and roll with the surface to be tested. In order to adapt to different detection surfaces, the user can adjust the direction of the pulley and slide the release block 604 located on the bottom side of the detection plate 502 so that the end of the release block 604 is disengaged from the first positioning groove 602 in the middle of the reversing shaft 601, and then the reversing shaft 601 is rotated. The positioning effect of the positioning column 607 and the second positioning groove 606 can ensure that the reversing shaft 601 rotates to the specified position, and then the release block 604 is released to fix the current angle of the reversing shaft 601, so that the pulley on the side of the reversing shaft 601 can fit the detection surface at different angles.

[0027] Specifically, Figure 5 , Figure 7As shown, the locking structure 7 includes a locking shaft 701, the side of the measuring seat 401 is rotatably connected with the locking shaft 701, the inner side of the measuring seat 401 is provided with a rotation groove 702, the end of the locking shaft 701 is rotatably connected with the measuring seat 401 through the rotation groove 702, the top side of the detection plate 502 is provided with a clamping groove 703, the side of the locking shaft 701 is clamped with the detection plate 502 through the clamping groove 703, the end of the locking shaft 701 is rotatably connected with a resistance block 704, and an eighth elastic member 705 is fixedly connected between the resistance block 704 and the measuring seat 401; After the direction of the reversing shaft 601 is adjusted, the user needs to fix the position of the detection plate 502 on one side and obtain the parallelism of the cylinder guide groove through the indicator rod 501 on the other side, press the locking shaft 701 on the side of the measuring seat 401 and then rotate it, so that the protruding part of the side of the locking shaft 701 slides into the engaging groove 703 on the detection plate 502. At this time, the detection plate 502 is relatively fixed to the measuring seat 401, and the indicator rod 501 thereon is always in the middle position. Then, the pulley on the side of the reversing shaft 601 on this side is fitted and slid with the measured surface, and the pulley on the other side is fitted and slid with the other detection surface. At this time, the parallelism of the cylinder guide can be obtained by observing whether the indicator rod 501 is offset.

[0028] When the present invention is in use, firstly, two racks 202 are provided in the telescopic sleeve 1 and meshed with the reversing gear 203 at the same time. By the synchronous sliding of the two racks 202 in the telescopic sleeve 1, the length of the device can be adjusted, and then the parallelism of the cylinder guide grooves of different widths can be detected. When in use, the user needs to rotate the release rotary block 201. At this time, the cylindrical structure on the bottom side of the release rotary block 201 will slide in the transverse groove 205 on the top side of the traction slider 204, and at the same time, the two traction sliders 204 will be pulled to slide toward the middle. At this time, the extrusion block 207 on the side of the traction slider 204 is disengaged from the abutment column 209 on the top of the fixed tooth block 208. Under the traction of the second elastic member 210, the end of the fixed tooth block 208 is disengaged from the rack 202 on the same side. The toothed rack 202 is in the engaged state, so that the user can freely slide the toothed rack 202 to adjust the measuring width. After the adjustment is completed, the release rotary block 201 is released, and the extrusion block 207 pushes the fixed toothed block 208 to re-engage with the toothed rack 202. At this time, due to the obstruction of the extrusion block 207, the fixed toothed block 208 will maintain the current position of the toothed rack 202, thereby maintaining the measuring length of the current device, which is convenient for parallelism detection of cylinder guide rails of different widths. After the preliminary adjustment of the measuring width is completed through the telescopic effect of the toothed rack 202, in order to further improve the accuracy of the adjustment, the user can rotate the adjusting rod 402 located at the top of the measuring seat 401 at both ends, and drive the second bevel gear 405 to rotate through the first bevel gear 404. Since the middle part of the second bevel gear 405 is aligned with the driving screw 40 3 threaded connection, and the measuring seat 401 and the rack 202 are slidably connected, so that the extension length of the measuring seat 401 can be further adjusted with the rotation of the driving screw 403, thereby improving the accuracy of the test. A support frame 301 is provided on the side of the telescopic sleeve 1, and a third elastic member 303 is connected between the support frame 301 and the telescopic sleeve 1. When the user rotates the release rotary block 201, the fixed tooth block 208 slides. At this time, the locking rod 304 is pulled by the fourth elastic member 305 to release the engagement state with the support frame 301, so that the support frame 301 slides out to support the middle part of the telescopic sleeve 1. After the user completes the adjustment of the telescopic length of the rack 202, the release rotary block 201 is released. At this time, the tooth block position is restored, thereby pushing the locking rod 304 is re-engaged with the locking groove 306 on the side of the support frame 301, thereby fixing the current supporting state of the support frame 301 and improving the stability of the support. After the adjustment of the measuring distance of the device is completed, a detection plate 502 slides on the bottom side of the measuring seat 401 at both ends, and the detection plate 502 slides along the guide rod 504. At the same time, a fifth elastic member 505 is fixed between both sides of the detection plate 502 and the measuring seat 401, which is used to keep the detection plate 502 in the middle position of the measuring seat 401. When the parallelism of the cylinder guide rail is measured by the detection plate 502, if the detection plate 502 is offset, the rotating sleeve 503 on the inner side of the detection plate 502 will drive the indicator rod 501 to rotate. The length of the indicator rod 501 located on the inner side of the measuring seat 401 is relatively large.The smaller offset at the bottom of the indicator rod 501 will be displayed as a larger offset on the top side, so that the operator can observe the parallelism and offset of the cylinder guide rails and improve the measurement accuracy. After the adjustment of the device is completed, a plurality of pulleys are provided on the bottom side of the detection plate 502. The accuracy of the test can be ensured by making the pulleys fit and roll with the surface to be tested. In order to adapt to different detection surfaces, the user can adjust the direction of the pulleys and slide the release block 604 on the bottom side of the detection plate 502 so that the end of the release block 604 is disengaged from the first positioning groove 602 in the middle of the reversing shaft 601, and then the reversing shaft 601 is rotated. The positioning effect of the positioning column 607 and the second positioning groove 606 can ensure that the reversing shaft 601 rotates to the specified position, and then the release block 604 is released to adjust the current reversing shaft 601. The angle is fixed so that the pulley on the side of the reversing shaft 601 can fit the detection surface at different angles. After the direction of the reversing shaft 601 is adjusted, the user needs to fix the position of the detection plate 502 on one side and obtain the parallelism of the cylinder guide groove through the indicator rod 501 on the other side. Press the locking shaft 701 on the side of the measuring seat 401 and then rotate it so that the protruding part of the side of the locking shaft 701 slides into the engaging groove 703 on the detection plate 502. At this time, the detection plate 502 is relatively fixed to the measuring seat 401, and the indicator rod 501 thereon is always located in the middle position. Then, the pulley on the side of the reversing shaft 601 on this side is fitted and slid with the measured surface, and the pulley on the other side is fitted and slid with the other detection surface. At this time, observe whether the indicator rod 501 is offset to obtain the parallelism of the cylinder guide.
