The top of the protective plate 52 is fixedly connected with a rubber pad 53 for directly contacting the bottom of the bridge. The front end of the protective plate 52 is fixedly connected with a moving handle 55 for facilitating the operator to move the protective plate 52. The rear end of the moving handle 55 is fixedly connected with a fixing box 56 for accommodating a fixing block 57. The rear end of the fixing box 56 is slidably connected with a fixing block 57 for fixing the protective plate 52. The top of the fixing block 57 is set as an inclined surface. When the inclined surface is squeezed, the fixing block 57 will be forced to move forward. The front end of the support platform 2 is provided with an adjustment slot 51 for accommodating the fixing block 57. The fixing block 57 is adapted to the adjusting slot 51. When the fixing block 57 is stuck in the adjusting slot 51, the protective plate 52 will be fixed and cannot move downward.

[0031] Reference Figure 1 - Figure 3 The front end of the fixed block 57 is fixedly connected with a fixing spring 58 for pushing the fixed block 57. The front end of the fixing spring 58 is fixedly connected to the inner wall of the moving handle 55. The fixing spring 58 will always push the fixed block 57 backward. The left end of the fixed block 57 is fixedly connected with a connecting rod 59 for driving the fixed block 57 to move. There are multiple groups of fixed boxes 56 and fixed blocks 57. The multiple groups of fixed boxes 56 and fixed blocks 57 are symmetrically arranged with the center line of the support platform 2 as the axis of symmetry. The two groups of fixed blocks 57 will fix the limit plate 54 from two points at the same time. The left end of the connecting rod 59 is fixedly connected to the right end of the other group of fixed blocks 57. By toggling the connecting rod 59, the two groups of fixed blocks 57 can be driven to move forward and out of the adjustment slot 51 at the same time.

[0032] Reference Figure 1 - Figure 3The positioning assembly 4 also includes a slider 43 for driving the positioning block 41 to move. The slider 43 passes through and is connected to the top of the support platform 2. The slider 43 slides on the top of the positioning block 41. When the positioning block 41 moves forward, it will not drive the slider 43 to move. The positioning block 41 can be driven forward by toggling the slider 43. The top of the slider 43 is fixedly connected to a connecting plate 44 for connecting the two sets of sliders 43. The top of the connecting plate 44 is fixedly connected to a handle 45 for facilitating the operator to move the connecting plate 44. The front end of the positioning block 41 is fixedly connected to a positioning spring 42 for pushing the positioning block 41 backward. The front end of the positioning spring 42 is fixedly connected to the support platform 2 The inner wall of the connecting plate 44, the positioning spring 42 will always push the positioning block 41 backward, the top of the connecting plate 44 passes through and is slidably connected with a locking block 46 for fixing the connecting plate 44, the right end of the locking block 46 is fixedly connected with a locking spring 48 for pushing the locking block 46, the right end of the locking spring 48 is fixedly connected to the inner wall of the connecting plate 44, the locking spring 48 will always push the locking block 46 to the left, and the top of the support platform 2 is provided with a locking groove 47 for accommodating the locking block 46, the locking block 46 slides on the inner wall of the locking groove 47, and the locking groove 47 is set to be L-shaped. When the locking block 46 is in the L-shaped horizontal groove of the locking groove 47, the connecting plate 44 will not be able to move forward and backward.

[0033] Working principle: When the bridge support 3 needs to be fixed, the bridge support 3 can be placed on the top of the support platform 2 first, and then the bridge support 3 can be pushed to move toward the center position of the support platform 2. When the bridge support 3 squeezes the inclined surface of the positioning block 41, it will force the positioning block 41 to move forward into the interior of the support platform 2. When the bridge support 3 moves to the center position of the support platform 2, the positioning spring 42 will push the positioning block 41 backward to make it move backward and block the left and right ends of the bridge support 3. At this time, the bridge support 3 will be fixed and cannot move. Then the bridge support 3 can be completely fixed to the top of the support platform 2 with bolts. Then the moving handle 55 can be pulled to drive the protective plate 52 to move upward. When the top of the rubber pad 53 contacts the bottom of the bridge, the moving handle 55 can be released, and the fixing spring 58 will push the fixing block 57 backward to make it move backward and get stuck in the inside of the adjustment slot 51. At this time, the protective plate 52 will be fixed and cannot move downward. At this time, the bridge support 3 will be covered by the protective plate 52.
