Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-5, this utility model provides a kind of technical scheme: include base 1, the lower surface four of described base 1
It is evenly distributed with four rolling 2 week；The upper center of described base 1 is vertically arranged with installing plate 3；In the both sides of described base 1
Portion all has screwed hole 4；Said two screwed hole 4 is symmetrical about installing plate 3；The top of described installing plate 3 is installed by rotating shaft
There is inclined-plane 5；The side center bottom of described installing plate 3 is hinged with expansion link 6；The top of described expansion link 6 and the bottom on inclined-plane 5
Middle part is hinged；The side, middle part of described expansion link 6 is provided with adjusting knob 7；The top middle portion of described installing plate 3 is provided with rotating shaft
Support 8；On described rotary shaft rack 8, fixed pulley 9 is installed；One middle side part of described installing plate 3 is provided with fixed plate 10；Described solid
The vertically above connection determining plate 10 has A spring 11；The lower section of described fixed plate 10 vertically connects B spring 12；Described A spring 11
