[0031] In the embodiment, the inner structure of the clamping assembly 35 is driven to move by the rocker arm 36, so that the connecting rod 34 can drive the support rod 31 and the clamping plate 33 to move inward at the same time, thereby achieving clamping of the protruding part of the side edge of the elevator guide rail and completing positioning of the two groups of guide rails, achieving auxiliary installation, most structures can be supported and limited by the composite plate 32, and the mechanical fixing mode is used to replace the magnetic fixing mode, external factor interference is reduced, and the service life is relatively long.

[0034] Specifically, as shown in Figure 1 , Figure 5 , the guide slide rod 45 is fixedly connected to the front side of the inner side of the composite pressing plate 41, the force-splitting slider 46 is slidingly connected to the outer side of the guide slide rod 45, the connecting rod 44 is rotatably connected to the outer side of the force-splitting slider 46, the connecting rod 44 is rotatably connected to the rear side of the inner side of the composite pressing plate 41, the second compression spring 47 is fixedly connected to the outer side of the force-splitting slider 46, and the second compression spring 47 is fixedly connected to the outer side of the guide slide rod 45.

[0035] In this embodiment: when clamped by the clamping plate 33, the composite pressing plate 41 between the clamping plate 33 and the connecting rod 34 will contract, there is an elastic element on the inner side of the composite pressing plate 41, which compresses the extension rod 42 and the first compression spring 43, plays a buffering role, at the same time, the connecting rod 44 in the composite pressing plate 41 rotates along the inner wall when it contracts, drives the force-splitting slider 46 to slide along the guide slide rod 45, and stretches the second compression spring 47. In this way, the clamping force is buffered and weakened, and is converted into elastic potential energy and mechanical work, avoiding problems such as damage to the guide rail and unstable installation.

[0036] Specifically, as shown in Figure 3 , Figure 4 , Figure 6 , the clamping assembly 35 comprises a pull rod 35a, a rotating block 35b, a main rotating shaft 35c, a secondary rotating shaft 35d, a ratchet wheel 35e, a pawl 35f and a torsional spring 35g.

[0037] Specifically, as shown in Figure 3 , Figure 4 , Figure 6 , the pull rod 35a is rotatably connected to the outer side of the connecting rod 34, the rotating block 35b is rotatably connected to the outer side of the pull rod 35a, the main rotating shaft 35c is fixedly connected to the bottom of the rotating block 35b, the main rotating shaft 35c is movably connected to the bottom of the composite plate 32, the rocker arm 36 is fixedly connected to the bottom of the main rotating shaft 35c, the ratchet wheel 35e is fixedly connected to the outer side of the main rotating shaft 35c, the pawl 35f is movably connected to the outer side of the ratchet wheel 35e, the pawl 35f is rotatably connected to the outer side of the secondary rotating shaft 35d, the secondary rotating shaft 35d is movably connected to the bottom of the composite plate 32, the torsional spring 35g is movably connected to the outer side of the pawl 35f, and the torsional spring 35g is movably connected to the outer side of the secondary rotating shaft 35d.

The pull rods 35a pull the two sets of connecting rods 34 and support rods 31 to move inward simultaneously. Since the clamping plate 33 is movably connected to the support rod 31, the rocker arm 36 drives the clamping plate 33 to clamp the protruding part on the side of the elevator guide rail.
