In addition, the main telescopic rod forms a gas spring, providing support and shock absorption.

[0014] 2. A docking seat is provided, which facilitates the connection and disassembly of the gas connection. Pulling the spring rod backward causes the wedge block to move backward, which can separate the docking buckle and the docking seat. The docking buckle and the docking seat can be flexibly installed for gas delivery. After the docking seat is removed, it can be connected to other docking buckles for repeated use.

[0015] 3. A connection channel is set up, providing a convenient pressure control function for pressure detection. Open the shut-off valve connected to the pneumatic telescopic rod to be tested, and then connect the pressure measuring cylinder and the pneumatic telescopic rod. Continue to pressurize the pneumatic telescopic rod. The pressure measuring cylinder pressurizes synchronously, pushing the guide frame upward and pushing the piston rod A and pressure scale outward. By observing the change of the pressure scale, the pressure of the pneumatic telescopic rod can be adjusted to the specified pressure. Attached Figure Description

[0019] like Figure 4 As shown, the connecting channel 3 includes: a threaded plug 301, which is fixedly installed on the rear side of the connecting channel 3; a pressure measuring cylinder 302, which is integrally installed on the top of the connecting channel 3, and two sets of guide frames 303 are integrally installed on the rear side of the pressure measuring cylinder 302, with an indicator strip 304 integrally installed between the two sets of guide frames 303; a piston rod A305, which is slidably installed inside the pressure measuring cylinder 302, and a spring is sleeved on the outside of the piston rod A305; and a pressure scale 306, which is fixedly installed at the top end of the piston rod A305 through the connecting channel 3, and is slidably connected to the guide frame 303.

[0020] like Figure 5 As shown, the main telescopic rod 4 includes: a rotating right-angle frame 401, with the rotating right-angle frame 401 rotatably mounted on the shaft end of the main telescopic rod 4; U-shaped brackets 402 are fixedly mounted on both sides of the rotating right-angle frame 401; and a slide block 403 is fixedly mounted inside the U-shaped bracket 402; a pneumatic telescopic rod 404, with a pneumatic telescopic rod 404 fixedly mounted between the inner walls of the two sides of the U-shaped bracket 402; a clamping plate 405 is fixedly mounted on the telescopic end of the pneumatic telescopic rod 404; the clamping plate 405 is slidably connected to the slide block 403; and a spring is provided between the portions of the two clamping plates 405 located inside the slide block 403; The telescopic rod 404 and the main telescopic rod 4 are connected by a pipe through the U-shaped bracket 402. The shut-off valve 103 connected to the gas telescopic rod 404 to be tested is opened, and then the pressure measuring cylinder 302 is connected to the gas telescopic rod 404. The pressure measuring cylinder 302 pressurizes the gas telescopic rod 404. The pressure measuring cylinder 302 pressurizes synchronously and pushes the guide frame 303 upward, pushing the piston rod A305 and the pressure scale 306 outward. By observing the change of the pressure scale 306, the pressure of the gas telescopic rod 404 can be adjusted to the specified pressure. Removing the threaded plug 301 can release the air and restore the main telescopic rod 4.

[0021] like Figure 6As shown, the control base 5 also includes: a slide frame 502, which is slidably mounted on the outside of the vertical frame 501 in conjunction with a guide rail; a pedal 503 is fixedly mounted on the rear side of the slide frame 502; a spring is provided at the bottom of the pedal 503; a connecting rod 504, which is hinged to the front side of the slide frame 502; a drive slider 505 is connected to the front end of the connecting rod 504; the drive slider 505 is slidably mounted on the top of the control base 5 in conjunction with the guide rail; and a drive rack 506 is fixedly mounted on the left side of the drive slider 505; and a foot pedal 5. 03, driving the slide frame 502 to descend, the slide frame 502 drives the connecting rod 504 to move forward and push the drive slider 505 and drive rack 506. The drive rack 506 drives the inner ratchet gear 801 to rotate, the inner ratchet gear 801 drives the driven shaft 8 to rotate, the driven shaft 8 drives the driven gear 802 to rotate, the driven gear 802 drives the driven gear plate 9 to rotate, and through the eccentric groove 901, drives the sliding pile 606 to move back and forth, and then uses the piston rod B603 to make the piston box 6 repeatedly change volume, thus generating the conveying function.

[0022] like Figure 7 As shown, the piston box 6 also includes: a piston rod B603, which is slidably disposed inside the rear side of the piston box 6. A moving block 604 is fixedly disposed at the rear end of the piston rod B603. A guide rod 605 is fixedly disposed at the rear end of the moving block 604. A sliding post 606 is fixedly disposed on the side of the moving block 604 near the driven gear plate 9. Outside air enters the piston box 6 through the one-way valve B601, then passes through the upper one-way valve B601, the input connecting pipe 602, and the handle 704, and then passes through the docking seat 7 to enter the intermediate card seat 10. In step 1, the air is then fed into the interior of the main telescopic rod 4 through the one-way valve A102, which expands the main telescopic rod 4. The inner corner of the steel structure is then fixed by the rotating right-angle bracket 401. When the main telescopic rod 4 is extended to its maximum, the pressurized air is fed into the pneumatic telescopic rod 404 through the U-shaped bracket 402. The pneumatic telescopic rod 404 extends and is clamped and fixed to the outside of the steel structure by the clamping plate 405, ensuring that the main telescopic rod 4 remains aligned with the steel structure. Finally, the rotating right-angle bracket 401 is fixed to the steel structure with bolts to complete the assembly.

[0023] like Figure 8 As shown, the docking seat 7 also includes a wedge block 702, and a spring rod 703 is fixedly installed on the rear side of the wedge block 702. The spring rod 703 is fitted with a spring and slidably connected to the docking seat 7. Pulling the spring rod 703 backward causes the wedge block 702 to move backward, which can separate the docking buckle 2 and the docking seat 7. After the docking seat 7 is removed, it can be connected to other docking buckles 2 for repeated use.

[0024] like Figure 6 and Figure 7As shown, the driven shaft 8 includes: an inner ratchet gear 801, which is fixedly installed at the right end of the driven shaft 8 and meshes with the drive rack 506; and a driven gear 802, which is fixedly installed on the outside of the driven shaft 8 and meshes with the driven gear disk 9.

[0025] like Figure 7 As shown, the driven gear 9 includes: an eccentric groove 901, which is provided on the outer side of the driven gear 9, and the sliding pile 606 slides in the eccentric groove 901; the front and rear positions of the two eccentric grooves 901 are staggered; and a support block 902, which is rotatably provided in the middle of the outer side of the eccentric groove 901, and the guide rod 605 slides in the support block 902.

[0026] The specific usage and function of this embodiment: In this invention, during use, the clamps 405 at the bottom of the two sets of rotating right-angle frames 401 are fastened to the lower inner part of the steel frame. Then, stepping on the pedal 503 causes the sliding frame 502 to descend. When the sliding frame 502 descends, it drives the connecting rod 504 to move forward, pushing the driving slider 505 and the driving rack 506. The driving rack 506 drives the inner ratchet gear 801 to rotate, which in turn drives the driven shaft 8 to rotate. The driven shaft 8 drives the driven gear 802 to rotate, which in turn drives the driven gear disc 9 to rotate. Through the eccentric groove 901, the sliding pile 606 moves back and forth, thereby using the piston rod B603 to repeatedly change the volume of the piston box 6, producing a conveying function. Outside air enters the piston box 6 through the one-way valve B601, and then passes through the upper one-way valve B601. The input connecting pipe 601 and handle 704 pass through the docking seat 7 into the intermediate card seat 101, and then through the one-way valve A102 into the interior of the main telescopic rod 4, which expands the main telescopic rod 4. The inner frame corner of the steel structure is then fixed by the rotating right-angle bracket 401. When the main telescopic rod 4 is extended to its maximum, the pressurized air passes through the U-shaped card seat 402 into the pneumatic telescopic rod 404. The pneumatic telescopic rod 404 extends and is clamped and fixed to the outside of the steel structure by the clamping plate 405, ensuring that the main telescopic rod 4 remains aligned with the steel structure. The assembly is then completed by fixing the rotating right-angle bracket 401 to the steel structure with bolts. Pulling the spring rod 703 backward causes the wedge block 702 to move backward, which can separate the docking buckle 2 and the docking seat 7. After the docking seat 7 is removed, it can be connected to other docking buckles 2 for repeated use.

[0027] According to the installation requirements, the pressure of the pneumatic telescopic rod 404 can be increased. The shut-off valve 103 connected to the pneumatic telescopic rod 404 to be tested is opened, and then the pressure measuring cylinder 302 is connected to the pneumatic telescopic rod 404. The pressure is increased by the pressure measuring cylinder 302, which pushes the guide frame 303 upward and pushes the piston rod A305 and pressure scale 306 outward. By observing the change of the pressure scale 306, the pressure of the pneumatic telescopic rod 404 can be adjusted to the specified pressure. Removing the threaded plug 301 can release the air and restore the main telescopic rod 4.
