[0038] See also Figure 1-6 The present application provides a manual auxiliary support mechanism for increasing the speed of left and right threads in the same direction by an inclined surface, including a mounting seat 10 and a same-direction increasing speed mechanism 20.

[0039] The same-direction speed increasing mechanism 20 includes a round rod nut 210, a supporting block 220 and left and right threaded screws 230. The round rod nut 210 is slidably connected to the mounting seat 10, and the supporting block 220 is slidably arranged on the mounting seat 10. A left threaded hole 240 is opened on the round rod nut 210, and a right threaded hole 250 is opened on the supporting block 220. The left and right threaded screws 230 are both threadedly connected to the left threaded hole 240 and the right threaded hole 250.

[0040] During the specific setting, the mounting seat 10 is installed on the work fixture. By rotating the left and right threaded screws 230, the front ends of the left and right threaded screws 230 rotate in the round rod nut 210 to achieve the purpose of movement of the left and right threaded screws 230. At the same time, the left and right threaded screws 230 drive the supporting round block 220 to slide on the mounting seat 10 to achieve the support purpose and facilitate adjustment.

[0041] See also Figure 2 and 4 The mounting seat 10 includes two mounting blocks 110 and a supporting oblique block 120. The supporting oblique block 120 is fixedly connected to the two mounting blocks 110. The supporting round block 220 is slidably arranged on the supporting oblique block 120. The tops of the two mounting blocks 110 are provided with limiting holes 30, and the bottoms of the limiting holes 30 are provided with through holes 40. The same connecting screw 50 is slidably arranged in the limiting holes 30 and the through holes 40. The side walls of the two mounting blocks 110 are provided with connecting holes 60. The two ends of the round rod nut 210 are respectively slidably connected to the two connecting holes 60. The supporting oblique block 120 is arranged in a right-angle trapezoidal shape, and the top of the supporting oblique block 120 is provided with a receiving groove 70.

[0042] During the specific setting, screw holes are opened on the existing tooling fixture. By matching the through holes 40 on the mounting block 110 with the screw holes on the tooling fixture, the connecting screw 50 is passed through the limiting hole 30 and the through hole 40 is connected to the screw hole, so as to achieve the installation purpose of the mounting seat 10, and the round rod nut 210 is passed through the two connecting holes 60 to achieve the installation purpose of the round rod nut 60.

[0043] See also Figure 3 , 5 and 6, the round rod nut 210 is provided with two first grooves 80, the two end openings of the left threaded hole 240 are respectively located on the two first grooves 80, the supporting round block 220 is provided with two second grooves 90, the two end openings of the right threaded hole 250 are respectively located on the two second grooves 90, the left and right threaded screws 230 include a left screw 2310 and a right screw 2320, the left screw 2310 is fixedly connected to the right screw 2320, the left screw 2310 is threadedly connected to the left threaded hole 240, the right screw 2320 is threadedly connected to the right threaded hole 250, and the diameter of the left screw 2310 is smaller than the diameter of the right screw 2320.

[0044] During the specific setting, the end of the left screw 2310 is passed through the right threaded hole 250, so that the end of the left screw 2310 is connected to the left threaded hole 240, and the right screw 2320 is connected to the right threaded hole 250. Since the diameter of the left screw 2310 is smaller than the diameter of the right screw 2320, the axial forward speed of the left screw 2310 in the left threaded hole 240 is higher than the axial forward speed of the right screw 2320 in the right threaded hole 250. Therefore, the left screw 2310 will drive the supporting block 220 to slide on the supporting bevel block 120 through the right screw 2320. At the same time, since the right screw 2320 rotates in the right threaded hole 250, the supporting block 220 will move along its axial direction on the right screw 2320, so that the supporting block 220 obtains two forward speeds, which is a speed-increasing process and is easy to adjust.

[0045] The working principle of the manual auxiliary support mechanism for the left and right threads of the surface is as follows: by rotating the left and right threaded screws 230, the left screw 2310 rotates in the left threaded hole 240, and the right screw 2320 rotates in the right threaded hole 250. Since the diameter of the left screw 2310 is smaller than the diameter of the right screw 2320, the axial advancement speed of the left screw 2310 in the left threaded hole 240 is higher than the axial advancement speed of the right screw 2320 in the right threaded hole 250. Therefore, the left screw 2310 will drive the supporting block 220 to slide on the supporting inclined block 120 through the right screw 2320. At the same time, since the right screw 2320 rotates in the right threaded hole 250, the supporting block 220 will move along its axial direction on the right screw 2320, thereby accelerating the adjustment speed of the supporting block 220.
