[0030] Referring to Figure 1 - Figure 3 -

[0031] Referring to Figure 1 - Figure 3The fixing assembly 7 includes a threaded block 72 for driving the extrusion block 73 to move. The threaded block 72 is slidably connected to the top of the support frame 1. The threaded block 72 can move horizontally left and right at the top of the support frame 1 without being separated from the top of the support frame 1. The right end of the threaded block 72 is fixedly connected to an extrusion block 73 for extruding the rail spare part. The right end face of the extrusion block 73 is set in an arc shape. When the extrusion block 73 is used to extrude the rail spare part, horizontal fixation can be achieved. At the same time, the extrusion block 73 will also squeeze the rail spare part downward to prevent it from moving upward. The left end of the slider 62 passes through and is slidably connected to a double-headed threaded rod 71 for driving the extrusion block 73 to move. The double-headed threaded rod 71 and the threaded block 72 are threadedly connected. By rotating The double-headed threaded rod 71 is rotated to drive the threaded block 72 to move left and right. The double-headed threaded rod 71 penetrates and slides on the inner wall of the support frame 1. The left end of the double-headed threaded rod 71 is fixedly connected with a screw block 74 for facilitating the operator to rotate the double-headed threaded rod 71. The screw block 74 is a regular hexagon and can be screwed with a wrench. There are multiple groups of extrusion blocks 73 and threaded blocks 72. The multiple groups of threaded blocks 72 and extrusion blocks 73 are symmetrically arranged with the center line of the slider 62 as the axis of symmetry. Using two groups of extrusion blocks 73 to fix the rail spare parts can prevent them from moving left and right. The other group of threaded blocks 72 is also threadedly connected to the outer wall of the double-headed threaded rod 71. By rotating the double-headed threaded rod 71, the two groups of threaded blocks 72 can be driven to move in opposite directions at the same time.

[0032] Reference Figure 2 - Figure 4 The front end of the slider 62 passes through and is slidably connected with a trapezoidal block 66 for fixing the slider 62. The front end of the trapezoidal block 66 is fixedly connected with an anti-slip strip 65 for fixing the trapezoidal block 66. The inner wall of the support frame 1 is provided with a fixing groove 61 for accommodating the anti-slip strip 65. The anti-slip strip 65 and the fixing groove 61 are adapted. When the anti-slip strip 65 is inserted into the interior of the fixing groove 61, the trapezoidal block 66 will be fixed and cannot move left and right. The top of the slider 62 passes through and is slidably connected with a slide plate 63 for squeezing the trapezoidal block 66. The top of the slide plate 63 is fixedly connected with a support plate 64 for supporting the rail spare parts. The slide plate 63 and the trapezoidal block 66 are adapted. The bottom end of the slide plate 63 is arranged as an inclined surface. When the slide plate 63 moves downward, it will force the top of the trapezoidal block 66 to move outward by squeezing it. There are multiple groups of trapezoidal blocks 66 and slide plates 63. The multiple groups of trapezoidal blocks 66 and slide plates 63 are symmetrically arranged with the center line of the slider 62 as the symmetry axis. The rear end of the trapezoidal block 66 is fixedly connected with an unlocking spring 67 for pulling the trapezoidal block 66 to move it toward the inside of the slider 62. The rear end of the unlocking spring 67 is fixedly connected to the front end of another group of trapezoidal blocks 66. When the trapezoidal block 66 is not squeezed, the unlocking spring 67 will pull the trapezoidal block 66 to make the anti-slip strip 65 detach from the inside of the fixed groove 61.

[0033] Working principle: When installing the connecting plate 2, multiple groups of T-shaped bolts 5 can be first clamped into the middle gaps of the segments. Then, the connecting plate 2 can be moved left and right to adjust its left and right positions. After the right end of the connecting plate 2 fits against the inner wall of the segment, the nut can be tightened to fix the connecting plate 2 inside the segment.

[0034] When fixing the rail spare parts, the slider 62 can be first moved left and right to adjust the fixing center position. Subsequently, the rail spare parts can be placed on the top of the support plate 64. The rail spare parts will squeeze the support plate 64 to drive the sliding plate 63 to move downward. The sliding plate 63 will squeeze the trapezoidal block 66 to force it to move outward. The outward movement of the trapezoidal block 66 will drive the anti-slip strip 65 to be clamped into the inner wall of the fixing groove 61. At this time, the slider 62 will be fixed and unable to move left and right. Then, a wrench can be used to rotate the screwing block 74 to drive the double-headed threaded rod 71 to rotate. The rotation of the double-headed threaded rod 71 can drive the two threaded blocks 72 to move simultaneously towards the center position to fix the rail spare parts on the top of the support plate 64.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
