The installation work is efficient, the production cost is low, and the economic benefit is high.

[0020] Since the limit seat includes a U-shaped outer plate and an L-shaped inner plate, the pallet is placed in the U-shaped groove of the U-shaped outer plate, the L-shaped inner plate is placed above the pallet, and the U-shaped outer plate and the L-shaped inner plate are fixedly connected, it is more convenient to produce and process the limit seat, and fixing the limit seat on the pallet is simpler and more convenient to use.

[0021] Since the corresponding bolts of the pallet are provided with adjustment grooves, the bolts pass through the adjustment grooves to detachably fix the U-shaped outer plate, the pallet and the L-shaped inner plate, the limit seat is better fixed to the pallet, and the operation of correcting the fixed position of the limit seat on the pallet is simpler and more convenient.

[0022] Since it also includes an adjusting screw, the rear end of the card plate is provided with a convex edge, and the convex edge is provided with a retaining hole; the limit seat is provided with a screw sleeve or a screw hole; the front end of the adjusting screw passes through the retaining hole of the convex edge and is threadedly connected with the screw sleeve or the screw hole of the limit seat, and the rear end extends out of the retaining hole of the convex edge and limit pads are provided at both ends of the retaining hole, so that the adjusting screw can be rotated to make the limit seat move forward or backward along the card plate; the rear end of the adjusting screw is provided with a handle for rotating the adjusting screw. When adjusting or correcting the fixed position of the limit seat on the card plate, the bolts that are detachably fixed to the limit seat and the card plate are loosened, and then the handle is rotated to make the limit seat move forward or backward along the card plate. Adjusting or correcting the fixed position of the limit seat on the card plate is simpler and more convenient to use.

[0023] Since it also includes a fixing block and a stud, the fixing block is fixed inside the front end of the limit seat and below the pressure plate, the fixing block is provided with a screw hole vertical to the bottom surface of the limit seat, the stud is threadedly connected to the screw hole, and the stud head is in contact with the bottom surface of the pressure plate. When the width of the clamp between the front end of the pressure plate and the card plate is too large or too small, the width of the clamp between the front end of the pressure plate and the card plate can be adjusted by rotating the stud, which makes the operation simpler and more convenient to use.

[0024] Since the fixing block is fixedly connected with the L-shaped inner plate to form a whole, the assembly operation is simpler, the overall structure is more compact, and the use is more convenient.

[0025] Since the pressure plate is provided with a screwdriver hole corresponding to the stud, the aperture of the screwdriver hole is smaller than the diameter of the stud head, when adjusting the width of the clamping opening between the front end of the pressure plate and the clamping plate, the width of the clamping opening between the front end of the pressure plate and the clamping plate can be adjusted by passing a screwdriver through the screwdriver hole and rotating the stud, which makes the adjustment operation simpler and more convenient to use.

[0026] Since the pressing plate includes a rear plate and a front plate, one end of the rear plate is hinged to a fixing pin, and the other end extends out of a limit seat and points to the upper rear end of the card plate; the front end of the front plate extends out of the limit seat and points to the front end of the card plate, and the rear end is placed above the rear plate and fixedly connected to the rear plate. The assembly operation is simpler, the operation of adjusting the distance that the front end of the pressing plate extends out of the limit seat is simpler, and it is more convenient to use.

[0027] Since there is a scale on the bottom surface of the pallet, the fixed position of the limit seat on the pallet can be adjusted or corrected intuitively and directly according to the installation requirements without the aid of other tools, which is more convenient to use and more efficient.

[0028] Since the inner bottom of the clamping opening at the front end of the clamping plate is provided with a positioning groove extending toward the limit seat, that is, the distance that the positioning groove extends toward the limit seat can be determined as the distance between the linkage door hinge fixing seat and the edge of the door leaf in one of the several opening modes of the linkage door inner cover, half cover and full cover, it is more convenient to use and simpler to operate.

[0029] Since a positioning plate is provided at the inner bottom of the positioning groove pointing downward and perpendicular to the bottom surface of the card plate, the distance between the positioning plate and the inner bottom of the card slot can be determined as the distance between the linkage door hinge fixing seat and the edge of the door leaf in one of the several opening modes of the linkage door inner cover, half cover and full cover, which is more convenient to use and simpler to operate.

[0030] Since a slot is provided on the inner wall of the top surface of the bayonet, the height of the slot is adapted to the edge thickness of the linked door hinge fixing seat, and is used to clamp the edge of the linked door hinge fixing seat. When in use, the edge of the linked door hinge fixing seat is inserted into the slot on the inner wall of the top surface of the bayonet. When the linked door hinge fixing seat is fixed on the door leaf for operation, the stability is better, the operation is simpler, and the use is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
