[0041] The bottom of each first ladder-shaped one-way clamping groove 206 is longitudinally screw-connected with a lead screw 210, one end of each lead screw 210 is provided with a motor 211, the motor 211 is fixedly connected with the column 10, the output end of the motor 211 is fixedly connected with the lead screw 210, and the number of the lead screw 210 and the motor 211 is both two and arranged longitudinally, so that the longitudinal translation of the active rod 207 is driven by the rotation of the lead screw 210.

[0042] Specifically, when fixing window frames of different sizes, the planar size of the screen window frame is input, the motor 211 drives the screw rod 210 to rotate to drive the movable rod 207 to move longitudinally along the first linear guide rail 205 to a specified position, then one end of the window frame is placed on the top of the movable rod 207, so that the window frame is located below the extrusion block 302 of the downward pressing mechanism 30, then the motor 211 is controlled to drive the screw rod 210 to rotate reversely to drive the movable rod 207 to move longitudinally along the first linear guide rail 205, so that the other end of the window frame is abutted against the second limiting strip 209 on the transverse beam 203, under the limitation of the first limiting strip 208 on the top of the movable rod 207, the window frame is clamped and fixed on the mounting platform, and the distance between the movable rod 207 and the transverse beam 203 is controlled, so that window frames of different sizes can be quickly fixed, manual operation required by workers is reduced, and labor intensity is reduced.

[0043] Referring to Figure 1 , Figure 5 , Figure 6 and Figure 7 , the downward pressing mechanism 30 comprises a rotating plate 301 rotatably connected to the top of the first limiting strip 208, one end of the rotating plate 301 is fixedly connected with an extrusion block 302, and the other end of the rotating plate 301 is fixedly connected with a mounting plate 303. An arc-shaped groove 304 is formed in the side surface of the mounting plate 303, and a connecting rod 308 is slidably connected in the arc-shaped groove 304.

[0044] The downward pressing mechanism 30 further comprises a push rod 305 horizontally sliding through the first limiting strip 208, one end of the push rod 305 is fixedly connected with an abutting plate 306, and the other end of the push rod 305 is fixedly connected with the connecting rod 308. The first limiting strip 208 is provided with a groove 307 for accommodating the abutting plate 306 on the side close to the abutting plate 306.

[0045] Specifically, after one end of the window frame is placed on the top of the movable rod 207, the window frame is located directly below the extrusion block 302, when the movable rod 207 pushes the window frame to move close to the transverse beam 203 for clamping and fixing, the abutting plate 306 is driven by the extrusion of the window frame to move the push rod 305 horizontally, the horizontally moving push rod 305 drives the connecting rod 308 to slide in the arc-shaped groove 304, when the connecting rod 308 moves to the other end of the arc-shaped groove 304, the connecting rod 308 drives the rotating plate 301 to rotate, the rotating rotating plate 301 causes the extrusion block 302 to press the window frame on the top of the movable rod 207, so that the window frame is prevented from being inclined to cause deviation during installation of the screen and the like, at the same time, when the window frame is tightly pressed on the mounting platform, potential danger caused by sudden upward bouncing of the window frame is reduced, and the operator is protected from injury.

[0046] Referring to Figure 1 , Figure 2 , Figure 6 and Figure 8The jacking mechanism 40 comprises a top rod 401 vertically and slidingly connected to the top of the movable rod 207, the movable rod 207 is internally provided with a containing cavity 402, the bottom of the top rod 401 extends into the containing cavity 402, and the bottom of the top rod 401 is fixedly connected with a first spring 406, the first spring 406 is fixedly connected with the bottom of the containing cavity 402 away from the top rod 401, and the bottom of the top rod 401 is provided with a through hole 403, and a pull rod 404 is horizontally and slidingly connected in the through hole 403.

[0047] One end of the pull rod 404 is fixedly connected with a triangular wedge 405, the other end of the pull rod 404 slidingly penetrates the side of the movable rod 207, and the other end of the pull rod 404 is fixedly connected with a horizontal rod 407, the horizontal rod 407 is fixedly connected with a vertical rod 408 at the middle, and the vertical rod 408 is fixedly connected with the push rod 305 away from the horizontal rod 407.

[0048] Specifically, when one end of the window frame is placed on the top of the movable rod 207, the push rod 305 drives the pull rod 404 to move horizontally in the same direction through the horizontal rod 407 and the vertical rod 408, the pull rod 404 drives the triangular wedge 405 to move during the movement, and the wedge 405 drives the top rod 401 to move into the containing cavity 402 during the movement through the through hole 403, and the top rod 401 compresses the first spring 406 at the same time.

[0049] When the window frame is assembled, the movable rod 207 needs to be moved away from the horizontal cross beam 203, at this time, the pressing mechanism 30 releases the pressing effect on the window frame, and the top rod 401 is driven to move upward by the elastic force of the first spring 406, and the one end of the window frame is lifted upward by the top rod 401, so that the surface scratch or other damage caused by directly prying the window frame with hands or tools can be avoided, and the appearance of the product is ensured to be intact.

[0052] In particular, during the movement of the movable rod 207 along the first linear guide rail 205, the third linear guide rail 502 at the bottom of the movable rod 207 moves along the surface of the fourth linear guide rail 504 through the trapezoidal bidirectional clamping grooves 503.

[0053] When fixing window frames of different sizes, the planar size of the screen door window frame is input to control the hydraulic cylinder 507 to drive the connecting rod 506 to move, thereby driving the two fourth linear guide rails 504 to move, so as to change the distance between the two fourth linear guide rails 504 at the top of the spacer 505, and during the transverse movement of the fourth linear guide rail 504, the fourth linear guide rail 504 moves along the surface of the second linear guide rail 501 and the third linear guide rail 502 respectively, and the spacer 505 is used to provide support under the window frame, and the spacer 505 can disperse the pressure from the first limiting strip 208, thereby reducing the risk of bending or twisting of the window frame due to excessive local stress.

[0055] In particular, after the window frame is placed on the spacer 505, the clamping plate 601 can be used to approach the side surface of the window frame, and the elastic force of the second spring 603 can drive the clamping plate 601 to tightly adhere to the side surface of the window frame through the sliding rod 602, and since the two spacers 505 are provided with the clamping plate 601 on the side surface, the two clamping plates 601 can clamp the two sides of the window frame, thereby avoiding the deviation of the window frame during the fixing of the window frame by the first limiting strip 208, and avoiding the surface scratch or other physical damage caused by the movement of the window frame.
