Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0039] This application discloses a modular support cylinder, including a cylinder body 100, a piston drive module 200, and a locking module 300. The piston drive module 200 is fitted inside the cylinder body 100. The locking module 300 includes a clamping member 310, an elastic sleeve 320, and a push rod 330. The first end of the clamping member 310 is connected to the piston drive module 200, and the second end extends along the side away from the piston drive module 200. The piston drive module 200 is used to push the clamping member 310 to move axially along the cylinder body 100, so as to drive the elastic sleeve 320 to clamp the push rod 330. In this embodiment, the piston drive module 200 can push the clamping member 310 to move axially along the cylinder body 100, so as to drive the elastic sleeve 320 to clamp the push rod 330 through the clamping member 310, thereby providing stable support for the target object (the support cylinder that realizes this process is the prior art, so all the components are not described in detail here).

[0040] Specifically, the cylinder body 100 has a cavity 110, and its lower end is open; the open end has a stepped through hole 120, and a lower cover 130 is provided in the stepped through hole 120; a first slot 121 is provided on the inner wall of the stepped through hole 120; a first locking member 122 is provided in the first slot 121 to limit the lower cover 130; the outer side of the clamping member 310 is provided with a first step 311, a second slot 312, and a second step 313 from bottom to top; a third slot 140 is provided on the cavity 110 between the first step 311 and the second slot 312; the piston drive module 200 includes a first piston 210, and the first step 311 abuts against the first piston 210.

[0041] In this embodiment, the cylinder body 100 has a cavity 110, and its lower end is open. A stepped through-hole 120 is provided in the open end, and a lower cover 130 is disposed within the stepped through-hole 120. A first retaining groove 121 is formed on the inner wall of the stepped through-hole 120. A first retaining member 122 is engaged within the first retaining groove 121 to abut against the lower cover 130. Thus, the upward movement of the lower cover 130 is limited by the stepped through-hole 120, and the downward movement of the lower cover 130 is limited by the first retaining member 122, preventing the lower cover 130 from moving within the cylinder body 100. Furthermore, the lower cover 130 can maintain a sealed contact with the inner wall of the stepped through-hole 120. The cylinder body 100 is sealed; the first step 311 of the clamping member 310 abuts against the first piston 210, so that when the first piston 210 moves upward, it can push the clamping member 310 to move upward and thus hold the push rod 330; by providing the first step 311, the second slot 312, and the second step 313 sequentially from bottom to top on the outside of the clamping member 310; and providing the third slot 140 located between the first step 311 and the second slot 312 on the cavity 110; thus, this application can switch between the two usage states of single piston state and double piston state through simple operation.

[0042] For example, firstly, when this application includes only one piston, the first piston 210, it is in single-piston use mode; for example, the use mode is as follows: the first piston 210 is pneumatically driven to move upward, thereby pushing the clamping member 310 to move upward and squeeze the elastic sleeve 320 to hold the push rod 330; the first piston 210 is pneumatically driven to move downward, thereby pushing the clamping member 310 to move downward away from the elastic sleeve 320 to release the push rod 330.

[0043] When switching to dual-piston operation, the lower cover 130 and the first locking member 122 are disassembled, and the first piston 210 is removed. Then, the other piston (the second piston) is placed into the cavity 110 and abuts against the second step 313. The separating component (e.g., a separating ring) is then detachably installed in the third slot 140. Finally, the first piston 210, the lower cover 130, and the first locking member 122 are reinstalled, thus switching to dual-piston operation. This application achieves modular design by using a shared cylinder body 100 and locking module 300, requiring only the replacement of components in the piston drive module 200 according to actual needs. This greatly improves component versatility and reduces manufacturing costs.

[0044] It should be noted that when switching between single-piston and double-piston states, the air path needs to be designed. However, the air path settings for both single-piston and double-piston states are based on existing technologies, and those skilled in the art can design them according to the actual situation. This is not the most important protection point.

[0045] To further understand the technical solution, preferred embodiments are given as examples below:

[0046] The piston drive module 200 also includes a second piston 220 and a separator ring 230 sleeved on the outside of the clamping member 310; the bottom of the second piston 220 is connected to a second locking member 221, and the second locking member 221 is detachably engaged with the second locking groove 312; the bottom of the separator ring 230 is connected to a third locking member 231, and the third locking member 231 is detachably engaged with the third locking groove 140.

[0047] In this embodiment, since the bottom of the separator ring 230 is connected to the third locking member 231, the separator ring 230 can be detachably installed in the third locking groove 140 through the third locking member 231, so that the separator ring 230 can be detached when needed; the second piston 220 can be detachably installed in the second locking groove 312 through the second locking member 221, so that the second piston 220 can be detached when needed.

[0048] In an optional or preferred embodiment, the first locking member 122, the second locking member 221, and the third locking member 231 are all elastic locking members, thereby facilitating a detachable connection between them and the corresponding slots; optionally, the first locking member 122, the second locking member 221, and the third locking member 231 are all elastic retaining springs, which can have a larger contact area and ensure connection stability; the elastic retaining springs can be C-shaped.

[0049] In an optional or preferred embodiment, the partition ring 230 is located between the first piston 210 and the second piston 220 to divide the cavity 110 into an upper chamber 111 and a lower chamber 112; the clamping member 310 is provided with an exhaust channel 314 that connects the lower chamber 112 with the inner cavity of the clamping member 310.

[0050] In this embodiment, when the first piston 210 is pushed upward, the air in the lower chamber 112 can be discharged from the inner cavity of the clamping member 310 along the gap, reducing the use of the vent and achieving a good dustproof effect; optionally, if it is in single-piston use mode at this time, such as Figure 3 As shown, the exhaust passage 314 can be blocked, thereby optimizing the air path design and improving the driving stability of the first piston 210.

[0051] In an optional or preferred embodiment, a lower air intake 150 is provided on the side wall of the cylinder 100; an air intake channel 315 is also provided on the clamping member 310; the lower air intake 150 connects the first piston 210 and the lower cover 130, and the air intake channel 315 connects the lower air intake 150 and the upper chamber 111.

[0052] In this embodiment, the air source can enter the space between the first piston 210 and the lower cover 130 through the lower air intake 150, thereby lifting the first piston 210 upward. At the same time, a portion of the airflow enters the upper chamber 111 from the air intake channel 315, thereby lifting the second piston 220 upward as well.

[0053] In an optional or preferred embodiment, the side wall of the cylinder 100 is also provided with an upper air intake 160 to connect an external air source with the top surface of the second piston 220; the arrangement of the upper and lower dual air sources makes the driving of the first piston 210 and the second piston 220 more stable.

[0054] In an optional or preferred embodiment, the cylinder body 100 further includes an upper cover 170; the upper cover 170 is detachably fixedly connected to the upper end of the cylinder body 100, further enhancing the modular and universal design of this application.

[0055] In an optional or preferred embodiment, the upper end of the cover 170 is provided with a connector 180; the bottom of the connector 180 is provided with a clamping ring 181, the inner wall of the clamping ring 181 presses against the upper outer wall of the elastic sleeve 320; when the clamping member 310 pushes the elastic sleeve 320 upward, the upper end of the elastic sleeve 320 gradually contracts inward under the inner compression of the clamping ring 181, thereby gripping the top rod 330 to increase its locking force.

[0056] In an optional or preferred embodiment, the cylinder body 100 further includes a dust cover 190 disposed on the outside of the upper cover 170; the dust cover 190 can prevent impurities such as liquid and dust from entering the cylinder body 100; the push rod 330 extends upward outside the cylinder body 100 and is connected to the support head 400 to abut against the receiving support object.

[0057] In an optional or preferred embodiment, the push rod 330 is disposed in the inner cavity of the clamping member 310 and extends axially along the cylinder body 100. A return spring 340 is disposed between the push rod 330 and the bottom of the inner cavity of the clamping member 310; an elastic sleeve 320 is disposed between the push rod 330 and the inner cavity of the clamping member 310. The design of the return spring 340 facilitates the reset of the push rod 330.
