[0004] In the above patent, the lifting plate is brought to a suitable position by continuously rotating the first threaded rod at the same time; however, this method of continuously rotating the lifting plate to adjust the position is relatively troublesome, resulting in low adjustment efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a stable geological surveying and mapping support to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a stable geological surveying and mapping support, comprising: a telescopic rod, two ends of the telescopic rod are connected to a fixed plate and a lifting plate, the front and rear sides of the center of the bottom surface of the lifting plate are fixedly connected with a hinge seat 1, the hinge seat 1 is rotatably connected to a support rod located between the fixed plate and the lifting plate, and the other end of the support rod is rotatably connected to a hinge seat 2, and the front and rear sides of the top surface of the right end of the fixed plate are horizontally symmetrically provided with movable grooves that slide with the movable rod, and a plurality of slots are provided on the opposite side wall of the movable rod. The two ends of the right wall of the fixed plate are fixedly and horizontally connected with a fixed rod located between the movable rod and the push rod, and an end surface of the fixed rod close to the movable rod is horizontally provided with a rectangular groove that slides with the insertion rod, the insertion rod and the slot are movably connected, and an end of the insertion rod away from the movable rod is horizontally fixedly connected with a spring and a guide rod that slides with the fixed rod, and the spring is sleeved on the outside of the guide rod.

[0007] Furthermore, the cross-section of the movable rod is convex-shaped, and a limiting block is fixedly connected to the front and rear walls of the front end of the movable rod. A limiting groove matching the limiting block is opened in the fixed plate, and the limiting groove is connected with the movable groove. The right end of the movable rod is fixedly connected to one end of the push rod.

[0008] Furthermore, the slot has a right-angled trapezoidal cross-section, the spacing between two adjacent slots is equal, the insertion rod is perpendicular to the movable rod, the cross-section of the end of the insertion rod away from the spring is a right-angled trapezoid, the inclined surface of the insertion rod and the inclined surface of the slot are in sliding contact, and the insertion rod and the slot are plugged in.

[0009] Furthermore, the spring is arranged in the rectangular groove, one end of the spring and the end away from the insertion rod is fixedly connected to the inner wall of the rectangular groove, and one end wall of the guide rod is fixedly connected to a connecting plate located between the fixed rods.

[0010] Furthermore, a rotating shaft parallel to the movable rod is rotatably connected above the center of the right wall of the fixed plate, and a turning handle located between the connecting plate and the push rod is fixedly connected to the center of the right end wall of the turning shaft, and the center of the turning handle and the center of the guide rod are on the same horizontal line.

One end of the connecting rod is hinged to the outer wall of the turning handle, and the other end of the connecting rod is hinged to the center of the connecting plate.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] When the lifting plate is lifted up, the movable rod is pushed leftward and slides leftward in the movable groove, and the movable rod simultaneously drives the hinge seat two to slide leftward on the top surface of the fixed plate, so that the lower end of the support rod rotates in the hinge seat two, and the other end of the support rod rotates around the hinge seat two and moves upward, and the upper end of the support rod rotates in the hinge seat one at this time, and the upper end of the support rod drives the hinge seat one to move up, thereby driving the lifting plate to move up, and the lifting plate drives the movable end of the telescopic rod to move up; when the movable rod slides leftward, the end wall of the plug rod slides on the movable rod. At this time, the spring connected to the plug rod is in a compressed state. When the slot on the movable rod contacts one end of the plug rod, under the action of its own elastic force, the spring pushes the plug rod into the slot, and continues to push the push rod to the left, and the slot and the inclined surface and the inclined surface of the plug rod slide, thereby causing the plug rod to slide in the rectangular slot to compress the spring, and the following slot principle is the same as above, until the lifting plate is raised to a suitable scale height; when the lifting plate is lowered, When the lifting plate is lowered, the lifting plate is moved downwardly, and the lifting plate is moved downwardly to the appropriate scale position. When the lifting plate reaches the appropriate scale position, the lever and the slot correspond to each other. The lifting plate is first released, the lever is inserted into the slot, and then the push rod is released to complete the lowering adjustment. The lifting plate can also be lowered to the lowest position by rotating the handle and the lifting plate is lowered to the lowest position under the gravity of the lifting plate, and then the above-mentioned height adjustment operation is performed, which can avoid applying external force to the push rod all the time. The problem of making the lifting plate reach the appropriate position by continuously rotating the first threaded rod at the same time is avoided, and the problem of low adjustment efficiency caused by the cumbersome method of continuously rotating the lifting plate position is solved. The height of the lifting plate can be adjusted by pushing the push rod, which is more convenient and improves the adjustment efficiency.

[0014] 2. The utility model lowers the lifting plate by rotating the handle to drive the rotating shaft to rotate, and the handle drives the connecting rod to move simultaneously when rotating. The connecting rod drives the connecting disk to move toward each other and drives the insertion rod to disengage from the slot, so that the lifting plate is lowered. By rotating a handle, the inconvenience of having to pull two connecting disks toward each other at the same time is solved, thereby improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
