A second embodiment of the present invention provides an attached lifting scaffold, which is substantially identical to the first embodiment except for the following.

Referring to fig. 4 and 5, two ends of the wall attachment device 2 are provided with guide plates 32 across the guide assembly 3, the guide plates 32 are fixedly connected with the wall attachment device 2, the guide assembly 3 is in sliding fit with the guide plates 32, a transverse through groove 31 is formed in a contact portion between the guide assembly 3 and the wall attachment device 2, a positioning nail 33 is arranged on the guide plate 32, and the positioning nail 33 penetrates through the guide plates 32 and penetrates through the through groove 31 to be in threaded connection with the wall attachment device 2.

It can be understood that the tightness of the positioning nail 33 can be adjusted by rotating the positioning nail 33, and when the positioning nail 33 is not screwed down, the position of the guide assembly 3 can be quickly adjusted back and forth due to the through groove 31, so that the guide assembly 3 can be applied to sliding rails 11 with different thicknesses without completely pulling out the positioning nail 33.

Specifically, the guide plate 32 is a U-shaped structure, two ends of the guide plate are fixedly connected with the wall attaching device 2, a sliding groove is formed between the guide plate 32 and the wall attaching device 2, and the guide assembly 3 is arranged in the sliding groove.

In practical use, the guide plate 32 needs to have a certain width, so that when the guide assembly 3 is located in the chute, the guide assembly 3 can be continuously kept in a transverse state, and the oblique upward or downward change is not easy to occur.

In addition, the positioning nail 33 includes a head 331 and a shaft 332, the shaft 332 is in threaded fit with the wall-attached device 2, the head 331 is configured to penetrate through the guide plate 32, and when the positioning nail 33 is tightened, the head 331 is in pressing contact with the guide component 3 to fix the position of the guide component 3.

The head 331 has a cylindrical structure, and the radius thereof should be larger than the width of the through-groove 31 so that the head 331 does not fall into the through-groove 31.

In this embodiment, the guide plate 32 is provided with a through hole, the head 331 is continuously located in the through hole, when the positioning pin 33 rotates, the head 331 only moves in the through hole and does not completely separate from the through hole, i.e. the guide plate 32 can also position the positioning pin 33.

In the present embodiment, the number of the positioning pins 33 is 1. In other embodiments, in order to further improve the stability of the guiding component 3 when fixed, a plurality of positioning pins 33 may be provided, and when the plurality of positioning pins 33 simultaneously fix the guiding component 3, the stability of the guiding component 3 can be greatly improved.

Preferably, the wall attachment device 2 is provided with a sliding block 34 facing the sliding rail 11, and the sliding block 34 is used for sliding fit with a groove of the sliding rail 11.

It can be understood that the stability of mutual sliding between the slide rail 11 and the wall attachment 2 can be further improved by using the guide assembly 3 and the slide block 34 in combination.

Furthermore, the wall attachment device 2 is provided with a threaded groove and a slot corresponding to the positioning nail 33 and the sliding block 34, respectively, the positioning nail 33 extends into the threaded groove, and the sliding block 34 is inserted into the slot.

Specifically, the thread groove is communicated with the slot, a fixing plate 341 is disposed on one side of the slider 34 away from the slide rail 11, the fixing plate 341 is thinner than the slider 34, the fixing plate 341 extends into the bottom of the slot, the end of the positioning nail 33 is a tip, and when the positioning nail 33 is screwed down, the positioning nail 33 is twisted or penetrates through the fixing plate 341.

The fixing plate 341 is made of a material having a lower hardness than the slider 34, and the fixing plate 341 is gradually broken or the fixing plate 341 is pressed and deformed in the process of gradually screwing the positioning pin 33.

It is understood that the fixing of the sliding block 34 can be performed when the positioning pin 33 penetrates the fixing plate 341, and the positions of the guide assembly 3 and the sliding block 34 are fixed simultaneously when the positioning pin 33 is tightened. When the fixing plate 341 is deformed by the positioning rod 33, for example, a groove is extruded, and the positioning rod 33 is located in the groove, the positioning effect can also be achieved.

In addition, in order to be applicable to the slider 34 of different lengths, set up the fixed plate 341 and enable the slider 34 to be applicable to the slot of different degree of depth, make slider 34's commonality stronger, and need not to set up the locating hole in advance on fixed plate 341.

In this embodiment, the fixing plate 341 is welded to the slider 34, in other embodiments, the fixing plate 341 may be detachably connected to the slider 34, and after the use of one time, the fixing plate 341 is replaced with a different fixing plate for continuous use.
