Support structure for table-board tool

Abstract

The present invention provides a table tool supporting structure which comprises an upper framework which is for the placement of the table tools and a folding mechanism which supports the upper framework and can be operated between unfolding and folding location. The folding mechanism comprises a couple of a first stabilizer and a second stabilizer which are connected with the upper framework, a first connector as well as a second connector and a third connector which are connected with the first connector. When the folding mechanism is operated to the folding location, the first connector, the second connector and the third connector together drive the second stabilizer close to the first stabilizer.

Description

technical field [0001] The present invention is related to the structure supporting the table-top tool (such as platform saw), more specifically, it refers to a support structure for the table-top tool that can be pushed to change the working position and conveniently folded. Background technique [0002] Fig. 1 to Fig. 3 are a kind of structure of known collapsible tripod 2, and this tripod 2 is the tabletop type tool that can support such as platform saw 1 etc., and its basic composition includes a platform 3, a pair of first leg 4, A pair of second legs 5 , a pair of connectors 6 , two telescopic cylinders 7 and two side plates 8 . The top of the platform 3 carries the platform saw 1, and is provided with a long chute 3a on the side, and a handle 3d is provided at the front end, and the side plate 8 is connected to the rear end, and the pair of first legs 4 are pivotally connected to the side plate 8 And it can be turned between the folded position in FIG. 2 and the unfo...

Problems solved by technology

[0003] When the tripod 2 is closed, it is convenient for people to roll the roller 9 on the ground and drag the platform saw 1 to change the working position, but when the tripod 2 is to be erected, people must first pull out the positioning pin 4a from the first hole 3b and pull out the first leg 4 outwards, then insert the positioning pin 4a into the second hole 3c to fix the first leg 4, after that, people must hold the handle 3d of the platform 3 and lift it up, and then During the lifting process, although the auxiliary thrust generated by the telescopic cylinder 7 can be used to gradually expand the second leg 5 and the connecting piece 6, people still need to apply considerable lifting force to resist the weight of the platform saw 1, so its operation It is not convenient; secondly, in the process of lifting, although people can stretch their feet to the bottom of the platform 3 and step on the pedal 6a fixed on the connecting piece 6 to help the expansion of the second leg 5, if the lifting force is not enough to resist The weight of the platform saw 1 or careless operation causes the platform 3 to collapse, and the platform 3 may crush the legs. Therefore, the folding structure of the tripod 2 is not a perfect and practical design
