Displacement structure for a support frame
A displacement structure for a support frame includes a fixing member and a slide member. The fixing member includes a first fixing portion, a connecting portion and a second fixing portion which are sequentially connected. The connecting portion has two ends connected to the first and second fixing portions, respectively, the first and second fixing portions are opposite to each other and separated by a clamping space which is provided for clamping a table plate. The slide member includes a first clamping portion fixed to one end of the stationary rod, and two opposite second clamping portions opposite to the first clamping portion. The first clamping portion and the second clamping portions are fixed together by a fixing bolt, there is a slide space between the first clamping portion and the second clamping portions, the first clamping portion and the second clamping portions clamp the first fixing portion.
1. A displacement structure for a support frame, the support frame including a stationary rod, and the displacement structure for the support frame comprising:
a fixing member including a first fixing portion, a connecting portion and a second fixing portion which are sequentially connected, in such a manner that the connecting portion has two ends connected to the first and second fixing portions, respectively, the first and second fixing portions are located towards each other and separated from each other by a clamping space which is provided for clamping a table plate; and
a slide member including a first clamping portion with a first surface fixed to one end of the stationary rod, and a second clamping portion opposite to the first clamping portion, the first clamping portion has a second surface fixed to the second clamping portion by a fixing bolt, there is a slide space between the first clamping portion and the second clamping portion, the first clamping portion and the second clamping portion clamp the first fixing portion, and the first fixing portion is located in the slide space.
2. The displacement structure for the support frame as claimed in claim 1 , wherein the first clamping portion includes a first lateral side and an opposite second lateral side, and there are two said second clamping portions located on the first and second lateral sides, respectively.
3. The displacement structure for the support frame as claimed in claim 2 , wherein the two second clamping portions are fixed to the first clamping portion by six fixing bolts, and both located on the second surface of the first clamping portion opposite the first surface.
4. The displacement structure for the support frame as claimed in claim 1 , wherein the first and second fixing portions each have one end fixed to the connecting portion, and both extend in the same direction.
5. The displacement structure for the support frame as claimed in claim 1 , wherein three pressing bolts are inserted in the second fixing portion and capable of moving towards or away from the first fixing portion, and the table plate is located between the first and second fixing portions.
6. The displacement structure for the support frame as claimed in claim 1 , wherein the slide member further includes two positioning bolts inserted through the first surface of the first clamping portion and stopped against the first fixing portion, so as to fix the slide member.
7. The displacement structure for the support frame as claimed in claim 1 , wherein a position where the second clamping portion comes into contact with the connecting portion is an initial position, and the slide member is capable of moving from the initial position by 100 mm.
