[0021] A threaded rod 201 is rotatably connected to the base plate 1. A motor 2 is fixedly installed on the base plate 1. The output end of the motor 2 is fixedly connected to the threaded rod 201. A guide rod 202 is fixedly connected to the base plate 1. A support plate 203 is slidably connected to the guide rod 202 and threadedly connected to the threaded rod 201.

[0022] The pressurization assembly includes an air pump 6 and pipes 307. The air pump 6 is fixedly installed on the support plate 203. An annular cavity 601 is opened on the cylinder 204. The output end of the air pump 6 is fixedly connected to the annular cavity 601. Five sets of pipes 307 are fixedly connected to the annular cavity 601. The ends of two sets of pipes 307 away from the annular cavity 601 are fixedly connected to the inner cavities of the five sets of sleeves 3. Each of the five sets of pipes 307 is equipped with a solenoid valve 308.

[0023] A filter box 7 is fixedly connected to the support plate 203. Multiple sets of activated carbon filter screens 702 are inserted into the filter box 7. An air inlet 701 is opened on the filter box 7. The input end of the air pump 6 is fixedly connected to the inner cavity of the filter box 7.

[0024] A sleeve 401 is fixedly connected to the bottom of the base plate 1. A piston disc 402 is slidably connected inside the sleeve 401. A spring 405 is fixedly connected between the piston disc 402 and the sleeve 401. A support rod 403 is fixedly connected to the piston disc 402. A base 404 is fixedly connected to the support rod 403. The sleeve 401 is fixedly connected to the inner cavity of the sleeve 3 through a pressure relief pipe 4. A pressure relief valve 406 is provided on the pressure relief pipe 4. A caster wheel 101 is fixedly installed at the bottom of the base plate 1.

[0025] When it is necessary to tighten the five sets of brake cables, the user first places the five sets of brake cables between the clamping plates 304 and 305 in the five sets of frames 205. At this time, the user opens the five sets of solenoid valves 308 on the five sets of pipes 307, and then starts the suction pump 6. The suction pump 6 draws in external gas, which then enters the filter box 7 through the air inlet 701 and comes into contact with the activated carbon filter 702. Because the activated carbon has a well-developed slit structure and abundant micropores, it can adsorb particulate matter in the gas into the micropores when the gas comes into contact with the activated carbon, thereby achieving the effect of filtering the gas. The filtered gas then... The gas is fed into the five sets of sleeves 3 through the annular cavity 601 and the five sets of pipes 307. Pipes 307 are equipped with one-way valves to pressurize the sleeves 3. The gas entering the sleeves 3 pushes the piston disc 301 downwards, stretching the spring 303. Simultaneously, the piston disc 301, via the connecting rod 302, drives the clamping plate 304 to abut against the clamping plate 305, thus clamping and fixing the five sets of brake cables. Furthermore, due to the continuous supply of gas to the sleeves 3, when the gas pressure inside the sleeves 3 exceeds the safety value set by the pressure relief valve 406, the pressure relief valve 406 automatically opens to release pressure. At this time, the gas inside the sleeves 3... Part of the gas is supplied into the sleeve 401 through the pressure relief pipe 4. The pressure relief pipe 4 is equipped with a one-way valve, which inflates the sleeve 401. This inflates the sleeve 401, causing the gas to push the piston disc 402 downwards and stretch the spring 804. Simultaneously, the piston disc 402, through the support rod 403, drives the base 404 downwards, causing the base 404 to contact the ground and lift the entire base plate 1, thus providing stable support for the base plate 1. Because gas is continuously supplied into the sleeve 401, when the gas pressure inside the sleeve 401 exceeds the safety value set on the pressure relief valve 408, the pressure relief valve 408 automatically... The pressure relief valve is opened, allowing some of the gas inside sleeve 2 401 to be discharged outside sleeve 2 401 through pressure relief pipe 2 407, thereby maintaining a constant gas pressure inside sleeve 2 401. Then, motor 2 is started, and motor 2 drives threaded rod 201 to rotate. Threaded rod 201 drives support plate 203 to move from right to left under the limiting guidance of guide rod 1 202, thereby achieving synchronous tightening of the five sets of brake cables. When it is necessary to synchronously loosen the five sets of brake cables, motor 2 drives threaded rod 201 to rotate, and threaded rod 201 drives support plate 203 to move from left to right under the limiting guidance of guide rod 1 202, thereby achieving synchronous loosening of the five sets of brake cables. It should be noted that pipe 307, conduit 602, and pressure relief pipe 4 are all flexible hoses, therefore, pipe 307, conduit 602, and pressure relief pipe 4 will not interfere with the left and right movement of frame 205. Example

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 A car inspection tool cable pulling mechanism, basically the same as in Embodiment 1, further includes a control drive assembly comprising five sets of threaded sleeves 609, which are respectively fixedly connected to five sets of frame bodies 205. Five sets of reciprocating lead screws 604 are symmetrically rotatably connected to the threaded sleeves 609 on the inner wall of the cylinder 204 at equal intervals. Five sets of guide rods 607 are equidistantly distributed and fixedly connected to the inner wall of the cylinder 204. Limit blocks 608 are fixedly connected to the guide rods 607. The five sets of threaded sleeves 609 slide relative to the five sets of guide rods 607. The cylinder 204 is connected to five sets of reciprocating screws 604 by threads. Five sets of guide tubes 602 are fixedly connected to the outer wall of the cylinder 204. One end of each of the five sets of guide tubes 602 is fixedly connected to the annular cavity 601, and the other end is fixedly connected to the inner cavity of the sleeve 3. Each of the five sets of guide tubes 602 is equipped with a solenoid valve 603. Each of the five sets of reciprocating screws 604 has an impeller 605 fixedly installed at one end of each of the five sets of guide tubes 602. Each guide tube 602 is equipped with a sealing ring 606, which fits against the outer wall of the reciprocating screw 604.

[0027] The clamping components include a spring 804, a connecting rod 802, and a nylon rope 806. The spring 804 is fixedly connected to the inner top wall of the five sets of frames 205. The end of the spring 804 away from the frame 205 is fixedly connected to a clamping plate 803. The inner bottom wall of the five sets of frames 205 is fixedly connected to a clamping plate 805. The clamping plates 803, 805, 304, and 305 are all provided with anti-slip pads 306. The connecting rod 802 is rotatably connected to the inner top wall of the frame 205 and rotatably connected to the clamping plate 803. The clamping plate 803 is provided with a guide component, which is slidably connected to the frame 205. One end of the nylon rope 806 is fixedly connected to the connecting rod 802, and the other end is fixedly connected to the inner wall of the cylinder 204.

[0028] The guide assembly includes a second guide rod 8 and a second limiting block 801. The second guide rod 8 is fixedly connected to the third clamping plate 803 and slidably connected to the frame 205. The second limiting block 801 is fixedly connected to the second guide rod 8.

[0029] When a secondary synchronous tightening of the brake cable is required, first close the solenoid valve 308 on the five sets of pipes 307, and open the solenoid valve 603 on the five sets of conduits 602. At this time, start the suction pump 6, which draws in external gas. The external gas then passes through the filter box 7, the annular cavity 601, and the conduit 602 sequentially and is delivered into the sleeve 3. The conduit 602 is equipped with a one-way valve. Gas entering the sleeve 3 that exceeds the safety value set by the pressure relief valve 406 is then delivered into the sleeve 401 through the pressure relief pipe 4, and then discharged from the sleeve 401 through the pressure relief pipe 407. At this time, when the gas passes through the five sets of conduits 602, the gas drives the five sets of reciprocating screws 604 to rotate synchronously through the impeller 605. The reciprocating screws 604 synchronously drive the five sets of threaded sleeves 609. Under the limiting guidance of the guide rod 607, the brake lines move synchronously towards the side closer to the support plate 203. At the same time, the five sets of threaded sleeves 609 drive the five sets of frames 205 to move synchronously, thereby enabling secondary synchronous tightening of multiple brake lines. Meanwhile, as the frames 205 move towards the side closer to the support plate 203, the nylon rope 806 is tensioned. At this time, the nylon rope 806 pulls the connecting rod 802 to rotate, thereby pushing the clamping plate three 803 to move downward under the limiting guidance of the guide rod two 8, and stretching the spring three 804. This causes the clamping plate three 803 to abut against the clamping plate four 805, thereby achieving secondary clamping and fixing of the brake lines. This improves the clamping and fixing effect of the stretched end of the brake lines, preventing the stretched end from falling off when the brake lines are tightened, which would affect the tightening of the brake lines. When it is necessary to perform secondary synchronous tightening on the two sets of brake cables separately, the user first closes the solenoid valve 603 on the other three sets of conduits 602. When the gas passes through the annular cavity 601, the gas only passes through the two sets of conduits 602. At this time, when the gas passes through the two sets of conduits 602, the gas drives the two sets of reciprocating screws 604 to rotate synchronously through the impeller 605. The reciprocating screws 604 synchronously drive the two sets of threaded sleeves 609 to move synchronously towards the side closer to the support plate 203 under the limiting guidance of the guide rod 607. At the same time, the two sets of threaded sleeves 609 drive the two sets of frames 205 to move synchronously, thereby realizing the secondary synchronous tightening of the two sets of brake cables. Example

[0030] Reference Figure 4 , Figure 5 and Figure 6A car inspection tool cable pulling mechanism, basically the same as in Embodiment 1, but further comprising: a pressure relief pipe 407 fixedly connected to the sleeve 401; a pressure relief valve 408 provided on the pressure relief pipe 407; a pipe 409 fixedly connected to the pressure relief pipe 407; a valve switch 410 connected to the pipe 409; a pipe 5 fixedly connected to the pressure relief pipe 401; and a valve switch 501 connected to the pipe 501. When the brake cable inspection is completed, the user first manually opens the valve switch 501. At this time, the gas in the sleeve 3 is discharged from the sleeve 3 through the pressure relief pipe 401 and the pipe 502, thereby stretching the spring 303 and pulling the piston disc 303. 1. Automatic reset. Simultaneously, piston disc 301 drives clamping plate 304 away from clamping plate 305 via connecting rod 302. Then, the brake cable can be removed. Then, the user manually opens valve switch 410. At this time, the gas in sleeve 401 is discharged from sleeve 401 through pressure relief pipe 407 and pipe 409. Then, the stretched spring 405 pulls piston disc 402 to reset. At the same time, piston disc 402 drives base 404 to move upward synchronously via support rod 403, so that base 404 is away from the ground, and the caster wheel 101 contacts the ground, thereby facilitating the movement of the entire base plate 1. Example

Step 2: The suction pump 6 adsorbs external gas and delivers it into the sleeve 3, pushing the clamping plate 304 to abut against the clamping plate 305. Step 3: Part of the gas in sleeve 1 3 is transported into sleeve 2 401 through pressure relief pipe 1 4, so that the gas pushes the base 404 downward and lifts the entire base plate 1. Step 4: Motor 2 drives threaded rod 201 to rotate, and threaded rod 201 drives support plate 203 to move from right to left under the limiting guidance of guide rod 202; Step 5: When it is necessary to tighten the brake cable synchronously for the second time, first close the solenoid valve 308 on the five sets of pipes 307 and open the solenoid valve 603 on the five sets of conduits 602. Step 6: When the gas passes through the five sets of conduits 602, the impeller 605 drives the five sets of reciprocating screws 604 to rotate synchronously, and drives the five sets of frames 205 to move towards the side closer to the support plate 203. Step 7: The nylon rope 806 pulls the connecting rod 802 to rotate, and pushes the clamping plate 3 803 to abut against the clamping plate 4 805; Step 8: When it is necessary to tighten the two sets of brake cables synchronously for a second time, first close the solenoid valves 603 on the other three sets of guide tubes 602. At this time, the two sets of reciprocating screws 604 rotate synchronously and drive the two sets of frames 205 to move closer to the support plate 203.
