The movable pressing block 330 is fixed to the lower end of the piston 230, and under the drive of the piston 230, the movable pressing block 330 can move up and down relative to the fixed pressing block 320. A profile is arranged between the fixed pressing block 320 and the movable pressing block 330, and under the drive of the crankshaft 210, the piston 230 drives the movable pressing block 330 to move towards the fixed pressing block 320, when the movable pressing block 330 moves, the profile and the shed cloth can be clamped, so that the profile can clamp the edge of the shed cloth.

[0025] As shown in Figure 1 , Figure 3 , Figure 4 , the distance module 40 includes a clamping frame 410 installed outside the execution module 30, a pressing member 420 installed on the clamping frame 410, and a clamping wheel 430.

[0026] The clamping frame 410 comprises a fixed frame 411 surrounding the fixed pressing block 320, a movable frame 412 parallel to the fixed frame 411 and surrounding the movable pressing block 330, and a limiting piece 413 arranged between the fixed frame 411 and the movable frame 412. The fixed frame 411 and the movable frame 412 are both substantially in a U-shaped structure, the openings of the fixed frame 411 and the movable frame 412 are both arranged away from the pressing module 20, the fixed frame 411 is fixedly installed on the outer side of the execution shell 310, the movable frame 412 surrounds the outer side of the execution shell 410, and the movable frame 412 is connected to the upper side of the fixed frame 411 in parallel and adjustably through the limiting piece 413. A pull handle 416 is installed on the outer side wall of the movable frame 412, the movable frame 412 can be moved relative to the fixed frame 411 through the pull handle 416, and the distance between the movable frame 412 and the fixed frame 411 can be changed. Positioning spikes 414 are installed on both sides of the opening of the fixed frame 411, the positioning spikes 414 are made of high-hardness material, and the positioning spikes 414 are used for hitting positioning on the profile. Specifically, support rods 415 are installed on both sides of the opening of the fixed frame 411, the positioning spikes 414 are inserted into the ends of the support rods 415, the hitting center of the positioning spikes 414 is located between the fixed frame 411 and the movable frame 412, and the positioning spikes 414 can hit and mark the surface of the profile when moving on the support rods 415. One end of the limiting piece 413 is installed on the fixed frame 411, the other end of the limiting piece 413 is movably inserted into the movable frame 412, the movable frame 412 always keeps parallel to the fixed frame 411 during movement, the limiting piece 413 is preferably a plurality of parallel pin shafts with shaft shoulders in the embodiment, the end with a larger diameter of the pin shaft is detachably installed on the fixed frame 411, the movable frame 412 is slidably inserted into the end with a smaller diameter of the pin shaft, and the sliding distance of the movable frame 412 on the limiting piece 413 is limited by the shaft shoulder. After the limiting length of the limiting piece 413 is adjusted, the minimum distance between the movable frame 412 and the fixed frame 411 can also be limited. The pressing pieces 420 are arranged at both ends of the fixed frame 411, the pressing pieces 420 have elastic properties, the pressing pieces 420 are detachably connected to the fixed frame 411 and the movable frame 412, the movable frame 412 has a tendency to move towards the fixed frame 411 by means of the elasticity of the pressing pieces 420, that is, the movable frame 412 and the fixed frame 411 have a clamping force. The clamping wheels 430 are installed at the ends of the fixed frame 411 and the movable frame 412, the clamping wheels 430 are divided into two groups, each group has two clamping wheels 430, each group of two clamping wheels 430 is arranged on the two sides of the profile corresponding to the movable frame 412 and the fixed frame 411, the clamping wheels 430 can press the profile under the extrusion of the fixed frame 411 and the movable frame 412, and the profile slides along the length direction by means of the sliding of the clamping wheels 430 and the clamping force.

[0027] In this embodiment, before using the movable step clamping device 100 for the windshield system profile, the positions of the fixed pressure block 320 and the movable pressure block 330 are adjusted by the control component 110 so that the fixed pressure block 320 and the movable pressure block 330 are located on the upper and lower sides of the profile respectively. Then, by pulling the handle 416, the movable frame 412 is moved away from the fixed frame 411, and the distance between the two clamping wheels 430 in each group is controlled so that the clamping wheels 430 are clamped on the upper and lower sides of the profile under the traction of the pressure component 420. After the clamping wheels 430 are in contact with the profile surface, the pins with different shoulder positions are replaced to control the distance between the movable frame 412 and the fixed frame 411. With the elastic traction of the pressure component 420, the clamping force of the clamping wheels 430 on the profile can be controlled. The clamping rollers 430 can roll along the profile. Since the profile needs to maintain its strength while also being able to change its opening size, most of the profile's sidewalls are pointed structures. Once the clamping rollers 430 are in place, they are difficult to detach from the profile surface naturally. The clamping rollers 430 on both sides of the profile can form a clamp, so that the clamping device 100 can only move along the length of the profile. When the clamping device 100 moves to the pressing position, it selects the positioning tip 414 away from the starting position along the moving direction and leaves a mark on the profile by tapping or other means, while simultaneously pressing the profile. The clamping device 100 is moved a fixed distance and continues to move to the next clamping position. After clamping, the mark is tapped. The above process is repeated until another positioning tip 414 and the mark coincide. The clamping continues at a fixed distance along the mark until the profile clamps the fabric.

[0028] In the above process, after the pressure module 20 and the execution module 30 are moved into place by the handheld module 10, the pneumatic motor 112 is started. The pneumatic motor 112 transmits torque to the crankshaft 210 through the gear set 220. Under the push of the eccentric section 211, the piston 230 drives the movable pressure block 330 to move towards the fixed pressure block 320 until the profile is squeezed and clamped on the edge of the tarpaulin, thus completing the clamping operation. Example

[0029] like Figure 5 As shown, in this embodiment, the limiting member 413 includes two screws fixedly installed on the fixed frame 411. Each screw has a limiting nut inserted into it. The movable frame 412 is movably inserted into the screw and rests on the limiting nut. The two limiting nuts are adjusted to be parallel on the screws. Under the constraint of the limiting nuts and screws, the movement direction of the movable frame 412 relative to the fixed frame 411 is restricted. The pressure member 420 is a tension spring with both ends attached. That is, when the pressure member 420 is blocked by the limiting nut, the movable frame 412 is restricted by the pressure member 420 to fix the distance between the screw and the fixed frame 411. In application, the position of the limiting nut on the screw should be adjusted according to the thickness of the profile until the clamping wheel 430 clamps the profile. Example

[0030] As Figure 6 and Figure 7 In the present embodiment, the limiting member 413 is preferably a scissor hinge mechanism. Specifically, the limiting member 413 includes a limiting rod 4131, a hinge rod 4132 inserted in the middle of the limiting rod 4131, and a limiting block 4133 slidably mounted on the fixed frame 411 and the movable frame 412. The limiting rod 4131 is provided with two groups of two limiting rods 4131 on both sides of the opening of the fixed frame 411, and the two limiting rods 4131 in each group are cross-placed. The hinge rod 4132 is inserted and mounted on the cross position of the limiting rod 4131, and the end of the limiting rod 4131 is hinged to the limiting block 4133. The limiting block 4133 is slidably clamped on the fixed frame 411 and the movable frame 412. The movement direction of the movable frame 412 is limited by the limiting rod 4131, so that the movable frame 412 can move parallel to the fixed frame 411, thereby enabling the wheel clamping device 430 to stably clamp the two sides of the profile, and facilitating the selection of the clamping position on the profile by the clamping gun Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
