Problems solved by technology

[0003] When adjusting the position of the working head in the above way, it is necessary to hold the column and overcome the gravity of the column and the working head to lift the column and the working head. It is necessary to hold the column and keep it in the required position for a period of time. In the actual operation process, it is difficult for the operator to keep still while holding a certain weight of the column and the working head. Therefore, the accuracy of this adjustment method is not high

Embodiment Construction

[0073] Figure 1 to Figure 4 A stent 100 of a first embodiment of the invention is shown.

[0074] see figure 1 and figure 2 , the support 100 of this embodiment includes a base 10 , a column 20 and a working head 30 connected in sequence.

[0075] The base 10 is placed on a horizontal plane when the support 100 is working, and is used to support the column 20 and the working head 30 . to combine image 3 , the base 10 of this embodiment includes a longitudinally extending hollow housing portion 12 and three supporting legs 11 evenly arranged outside the housing portion 12. The three supporting legs 11 are pivotally arranged on the three housing portions 13 outside the housing portion 12 Inside (only two are shown in the figure), the side of the receiving portion 13 facing away from the working head 30 is provided with an opening 131 for the supporting leg 11 to pivot freely, and the opening 131 has a first edge 132 and a second edge 133, wherein, The first edge 132 is t...

Abstract

The invention provides a support which comprises a base, a vertical pillar and a working head. The base is used for supporting the support. The working head comprises a working portion which contacts with a workpiece. An adjusting mechanism used for driving the working portion to do linear motion is arranged on the support. The adjusting mechanism is provided with an input end, an output end and a motion converting mechanism, wherein the output end is connected with the working portion and used for outputting the linear motion, and the motion converting mechanism is arranged between the input end and the output end. The motion converting mechanism is driven by the input end to drive the output end to move, enables the output end to stop doing the linear motion and maintain the output end at a position where the motion is stopped when the input end stops moving. An operator does not need to overcome gravity of the vertical pillar and the working head, holds the vertical pillar within a certain time, enables the vertical pillar to keep still, and only needs to attentively control input of the input end. Accordingly, the operator can ensure that the working head moves in a preset distance, and can accurately and easily adjust the position of the working head.

Description

technical field [0001] The invention relates to a bracket. Background technique [0002] A conventional stand consists of sequentially connected bases, uprights and working heads. When in use, the base stands on a horizontal surface and is used to support the column and the working head. The vertical extension of the column has a certain length, one end of which is adjustablely connected to the base, and the other end is fixedly connected to the working head. The working head has a certain height relative to the horizontal plane for supporting objects. The operator can hold the column and move the column to a desired position relative to the base, and then fix the column relative to the base to adjust the height of the working head connected to the column to meet different usage requirements. [0003] When adjusting the position of the working head in the above way, it is necessary to hold the column and overcome the gravity of the column and the working head to lift the ...
