[0034] In some specific embodiments, see Figure 1 , at least one magnet 111 is embedded in one side wall of the clamping groove 110; and / or at least one magnet 111 is embedded in the bottom surface of the clamping groove 110. The magnet 111 has a strong enough magnetism to adsorb and fix the guide rail docking tool on the "T"-shaped guide rail, so that the construction worker can operate the guide rail docking tool with one hand.
[0035] In some specific embodiments, see Figure 2 A handle 120 is fixedly provided on the tool body 100 to facilitate construction workers to grasp the guide rail docking tool.
[0036] In some specific embodiments, see Figure 2 The tool body 100 is provided with an observation window 130, which is connected to the clamping groove 110.

[0037] Figure 3A schematic diagram of the structure of the clamping plate in an embodiment of the utility model is shown, the clamping plate 200 includes a clamping piece 220 and a reinforcing piece 230 connected as one body, the clamping piece 220 and the reinforcing piece 230 are perpendicular to each other, the clamping piece 220 is located in the clamping groove 110, and the reinforcing piece 230 is located outside the clamping groove 110. The reinforcing piece 230 and the clamping piece 220 are connected perpendicularly to each other, which can effectively enhance the strength of the clamping piece 220, so that the clamping piece 220 is not prone to local bending, which is beneficial to ensure the alignment accuracy when the upper guide rail 20 and the lower guide rail 10 are docked; the guide plate 210 and the clamping piece 220 are connected as one body, which is convenient for guiding the upper guide rail 20 into the clamping groove 110.
[0038] Specifically, one end of the clip 220 away from the guide plate 210 is movably connected to the tool body 100 based on the first connection part 221, and one end of the guide plate 210 away from the clip 220 is movably connected to the tool body 100 based on the second connection part 211, that is, the two ends of the clamp 200 are movably connected to the tool body 100 through the first connection part 221 and the second connection part 211, which can ensure the connection stability between the clamp 200 and the tool body 100.
[0039] Furthermore, the reinforcing sheet 230 is movably connected to the tool body 100 based on the third connecting portion 231 , which can further enhance the connection stability between the clamping plate 200 and the tool body 100 .
[0040] Figure 4 Shows Figure 2 In the enlarged structural diagram of the A area, at least two limiters 510 are arranged on the outside of the tool body 100, and each limiter 510 is sleeved with a spring 520; the clamping plate 200 is movably arranged on the at least two limiters 510, and the spring 520 is located between the clamping plate 200 and the tool body 100; under the action of the spring 520, the guide rail accommodating space has a tendency to widen. When the locking mechanism 300 is released, the spring 520 can make the clamping plate 200 automatically detach from the guide rail surface and reset, so that the guide rail accommodating space returns to its original width, which is convenient for the next use of the guide rail docking tool.
[0041] Figure 5 The bottom view of the guide rail docking tool in the embodiment of the utility model is shown. An oil groove 112 is provided on the side wall of the clamping groove 110. The oil groove 112 is connected to the bottom surface of the clamping groove 110. The oil groove 112 is located on the side away from the clamping plate 200. There is usually oil stain on the outer surface of the "T"-shaped guide rail. When the guide rail docking tool is used, the oil stain will be squeezed to the bottom corner of the clamping groove 110. The oil groove 112 can store the oil stain. The length of the oil groove 112 is comparable to that of the clamping groove 110, so as to prevent the oil stain from hindering the fit between the guide rail and the guide rail docking tool.
[0042] In some specific embodiments, lining plates are provided in the clamping groove 110 and the guide groove 410. The lining plates are made of strong and wear-resistant materials and can be replaced even if they are worn. They protect the inner surfaces of the clamping groove 110 and the guide groove 410 and prevent damage to the tool body 100.
[0043] In some specific embodiments, see Figure 1 , the locking mechanism 300 includes at least two handle screws, the handle end of each handle screw is located outside the tool body 100, the screw end of each handle screw is arranged in the tool body 100 based on thread rotation, and the screw end of each handle screw extends into the adjustment accommodating space. By rotating the handle screw, the length of the screw end of the handle screw extending into the adjustment accommodating space can be adjusted; when the screw end of the handle screw is against the clamping plate 200, the size of the guide rail accommodating space can be adjusted, so that the guide rail can be clamped in the guide rail accommodating space. In the tool body 100, at least one handle screw is required for locking in the area corresponding to the lower guide rail 10, and at least one handle screw is also required for locking in the area corresponding to the upper guide rail 20; further, a handle screw can also be set in the area of the lower guide rail 10 close to the connection between the upper guide rail 20 and the lower guide rail 10 for locking.
[0044] The guide rail docking tool can be independently fixed to the upper end of the lower guide rail 10 by the handle screw, which is convenient for hands-free docking of the guide rails and has high operational safety. After the upper guide rail 20 and the lower guide rail 10 are correctly docked, the clamping plate 200 can be tightened by the handle screw, so that the upper guide rail 20 and the lower guide rail 10 are simultaneously pressed against one side wall of the clamping groove 110 to ensure that the lateral guide surfaces of the upper guide rail 20 and the lower guide rail 10 can be coplanar.
[0045] In some specific embodiments, there is a first angle between the connected side walls of the guide groove 410 and the clamping groove 110 , and the angle range of the first angle is 135° to 170°, ensuring that the guide groove 410 can smoothly guide the guide rail into the clamping groove 110 .
[0046] In some specific embodiments, the width of the guide rail accommodating space ranges from 5 to 36 mm, which can be suitable for docking with various elevator guide rails, for example, T45, T50, T70, T75, T78, T82, T89, T90, T114, T125, T127, T140, etc., with wide applicability and high practicality.
[0047] In some specific embodiments, the length ratio of the guide head 400 to the tool body 100 is 1:1.8-2.0 (the length of the tool body 100 does not include the length of the guide head 400), which can avoid top-heavyness and make it easier to use.
[0048] Figure 6 The figure shows the use state of the guide rail docking tool in the embodiment of the utility model.
[0049] The use process of the guide rail docking tool of the utility model is:
[0050] First, fix the guide rail docking tool on the upper end of the lower guide rail 10. Specifically, fit the upper end of the lower guide rail 10 in the guide rail accommodating space, and use the handle screw to tighten the clamping plate 200 against the outer wall of the lower guide rail 10, so as to firmly clamp the lower guide rail 10 and make the guide rail docking tool independently fixed to the upper end of the lower guide rail 10; then, place the lower end of the upper guide rail 20 into the guide groove 410, and the upper guide rail 20 can slide from the guide groove 410 along the guide plate 210 into the guide rail accommodating space. At the same time, the upper guide rail 20 will automatically align and dock with the lower guide rail 10 under the constraint of the guide rail accommodating space (the docking status can be observed from the observation window 130); finally, adjust the handle screw to tighten the clamping plate 200 against the side walls of the upper guide rail 20 and the lower guide rail 10, so that the upper guide rail 20 and the lower guide rail 10 are coplanar, ensuring the docking accuracy of the upper guide rail 20 and the lower guide rail 10.
