[0022] The tool table 3 has a rotating connection end 31 and a sliding end 32 at its two ends. The rotating connection end 31 is set on the first crossbar 15 of the first bracket 1, and the sliding end 32 is slidably connected to the second support rod 22 and the fourth support rod 24 of the second bracket 2.

[0023] The sliding end 32 of the tool table 3 is equipped with a locking device 4. At least two pairs of locking holes 21 are provided from top to bottom on the second support rod 22 and the fourth support rod 24. Generally, two or three pairs of locking holes 21 are set so that the working position of the tool table 3 can be set according to the site conditions. The locking device 4 is locked with the locking holes 21 at different positions to fix the angle of the first bracket 1 and the second bracket 2 relative to each other, thereby fixing the working position state of the tool table 3.

[0024] like Figure 4 As shown, when the locking device 4 is locked with the upper locking hole 21, the retractable bracket is in the extended and lowered state, allowing for the loading and unloading of small machines, or as... Figure 5 The image shows a trolley used to transport small machines; such as Figure 6 As shown, when the locking device 4 is locked with the locking hole 21 at the lower end, the retractable bracket is in the raised state, and at this time the retractable bracket can be used as a construction bracket for small machines.

[0025] Furthermore, the second bracket 2 is also equipped with a pull rod 25, the two ends of which are connected to the tops of the second support rod 22 and the fourth support rod 24, respectively. When the locking device 4 disengages from the locking hole 21, the pull rod 25 can be pulled or pressed to help raise or lower the bracket.

[0026] The locking device 4 is located on the lower surface of the sliding end 32 of the tool table 3, such as... Figure 3As shown, the system includes a mounting plate 40, two opposing first locking rods 41 and second locking rods 42, and two opposing first locking rod seats 43 and second locking rod seats 44. The first locking rod 41 is disposed in the first locking rod seat 43, and the second locking rod 42 is disposed in the second locking rod seat 44. The first locking rod seat 43 and the second locking rod seat 44 are disposed at both ends of the mounting plate 40 and are arranged in a straight line. The first locking rod 41 can be inserted into the locking hole 21 of the second support rod 22, and the second locking rod 42 can be inserted into the locking hole 21 of the fourth support rod 24.

[0027] The first locking rod seat 43 includes a first outer fixing plate 431 and a first inner fixing plate 432 disposed on one side of the mounting plate 40. Both the first outer fixing plate 431 and the first inner fixing plate 432 are provided with through holes for the first locking rod 41 to pass through. A first spring 433 is disposed between the first outer fixing plate 431 and the first inner fixing plate 432. The first locking rod 41 passes through the through hole of the first inner fixing plate 432, the first spring 433 and the through hole of the first outer fixing plate 431 in sequence from the side of the first inner fixing plate 432 toward the direction of the first outer fixing plate 431. A first spring limiting member 413 is provided on the first locking rod 41 near the first outer fixing plate 431. One end of the first spring 433 abuts against the first spring limiting member 413 and the other end abuts against the first inner fixing plate 432. When the first locking rod 41 is pulled inward, that is, towards the first inner fixed plate 432, the first spring 433 is compressed. When the force pulling the first locking rod 41 disappears, the first locking rod 41 will maintain its tendency to move towards the first outer fixed plate 431 under the restoring force of the first spring 433. When the tool table 3 slides to the position of the locking hole 21, the first locking rod 41 will be inserted into the locking hole 21 under the restoring force of the first spring 433.

[0028] The second locking rod seat 44, located on the opposite side of the first locking rod seat 43, includes a second outer fixing plate 441 and a second inner fixing plate 442 located on the other side of the mounting plate 40. Both the second outer fixing plate 441 and the second inner fixing plate 442 have through holes for the second locking rod 42 to pass through. A second spring 443 is disposed between the second outer fixing plate 441 and the second inner fixing plate 442. The second locking rod 42 passes sequentially from one side of the second inner fixing plate 442 toward the second outer fixing plate 441 through the through hole of the second inner fixing plate 442, the second spring 443, and the second outer fixing plate 441. The second locking rod 42 has a second spring limiting member 423 near the second outer fixing plate 441. One end of the second spring 443 abuts against the second spring limiting member 423, and the other end abuts against the second inner fixing plate 442. Similar to the movement of the first locking rod 41, when the second locking rod 42 is pulled inward, i.e., towards the second inner fixing plate 442, the second spring 443 is compressed. When the force pulling the second locking rod 42 disappears, the second locking rod 42 will maintain its tendency to move towards the second outer fixing plate 441 under the restoring force of the second spring 443. When the tool table 3 slides to the position of the locking hole 21, the second locking rod 42 will be inserted into the locking hole 21 under the restoring force of the second spring 443. At this time, the movement of the second locking rod 42 and the first locking rod 41 is synchronized. The first locking rod 41 is inserted into the locking hole on the second support rod 22, and the second locking rod 42 is inserted into the corresponding locking hole 21 on the fourth support rod 24, thus jointly locking the position of the tool table 3.

[0029] Furthermore, such as Figure 3 As shown, the first locking bar 41 includes a first locking part 411 and a first grip part 412, with the first locking part 411 and the first grip part 412 at an angle greater than 50 degrees. 0 The angle is fixed and connected, and is generally designed to be perpendicular to each other; the first locking part 411 passes through the through hole of the first inner fixing plate 432, the first spring 433 and the through hole of the first outer fixing plate 431 in sequence from one side of the first inner fixing plate 432 toward the first outer fixing plate 431; the first locking part 411 is provided with a first spring limiting member 413 near the first outer fixing plate 431; one end of the first spring 433 abuts against the first spring limiting member 413 and the other end abuts against the first inner fixing plate 432; The second locking lever 42 includes a second locking part 421 and a second gripping part 422, wherein the second locking part 421 and the second gripping part 422 are at an angle greater than 50 degrees. 0The angle is fixed and connected, and is generally designed to be perpendicular to each other; the second locking part 421 passes through the through hole of the second inner fixing plate 442, the second spring 443 and the through hole of the second outer fixing plate 441 in sequence from one side of the second inner fixing plate 442 toward the second outer fixing plate 441. The second locking part 421 is provided with a second spring limiting member 423 near the second outer fixing plate 441. One end of the second spring 443 abuts against the second spring limiting member 423 and the other end abuts against the second inner fixing plate 442. The first gripping part 412 and the second gripping part 422 are located between the first inner fixing plate 432 and the second inner fixing plate 442. In actual operation, from Figure 6 State transition to Figure 4 In the current state, when the first grip 412 and the second grip 422 are held together by hand and forcefully brought together, the first locking part 411 and the second locking part 421 disengage from their respective locking holes 21. Then, pressing down on the pull rod 25 on the second bracket 2 causes the first bracket 1 and the second bracket 2 to rotate and unfold. At this time, the tool table 3 can slide on the second support rod 22 and the fourth support rod 24. When the tool table 3 slides to the position of the other pair of locking holes 21 at the lower position, the first locking part 411 and the second locking part 421 are inserted into the locking holes 21 under the restoring force of the first spring 433 and the second spring 443, and the retractable bracket is in position. Figure 4 The state shown. At this point, the machine on tool table 3 can be removed, or, as shown... Figure 5 As shown, the retractable support frame is used as a trolley to move the machine to another construction location.

[0030] Preferably, such as Figure 3 As shown, a sliding limit block 7 is provided at each end of the mounting plate 40. Each sliding limit block 7 includes a fixedly connected abutment part 71 and a support part 72. The abutment part 71 and the support part 72 are L-shaped. The abutment parts 71 of the two sliding limit blocks 7 abut against the inner sides of the second support rod 22 and the fourth support rod 24, respectively, and the support parts 72 of the two sliding limit blocks 7 support the lower sides of the second support rod 22 and the fourth support rod 24, respectively. In this way, the tool table 3 will not fall off the support rod during the sliding process, and safety is guaranteed.

[0031] Furthermore, the mounting plate 40 is provided with screw holes, and the locking device 4 is fixed to the sliding end 32 of the tool table 3 with screws through the screw holes.

[0032] To facilitate use when the support is deployed as a trolley, the lower ends of the first push rod 11 and the third push rod 13 are symmetrically provided with handles 12, which make it easy to lift the support and push it.

[0033] To make the raising and lowering of tool table 3 more gradual, such as Figure 1 , Figure 2As shown, the first bracket 1 is also provided with a second crossbar 17, which is located below the first crossbar 15; an elastic buffer 6 is provided between the second crossbar 17 and the wheel axle 52, with one end of the elastic buffer 6 connected to the wheel axle 52 and the other end connected to the second crossbar 17. The elastic buffer 6 is generally made of nitrogen spring, and it is best to provide two springs.
