[0008] An auxiliary component, which is arranged on the support base and is used to support, fold, store and elevate the device;

[0009] A lateral adjustment component, which is disposed on the support seat and is used to adjust the lateral angle of the measuring instrument;

[0010] A longitudinal adjustment component is arranged on the support frame and is used to adjust the longitudinal angle of the measuring instrument.

[0011] In a possible design, the auxiliary component includes three connecting frames fixedly arranged in a ring shape on the outside of the support seat, and the inner sides of the three connecting frames are rotatably provided with damping shafts, the outsides of the three damping shafts are fixedly provided with support rods, one ends of the three support rods are provided with sliding cavities, and the insides of the three sliding cavities are slidably provided with sliding rods, one side of the three support rods is provided with sliding grooves connected to the sliding cavities, the ends of the three sliding rods located inside the sliding cavities are fixedly provided with connecting rods, the three connecting rods pass through the sliding grooves and extend to the outside, the ends of the three connecting rods located outside the support rods are rotatably provided with locking handles, and the outsides of the three connecting rods are sleeved with gaskets under the locking handles.

The driving gear meshes with the driven gear for transmission, and an adjustment rod is fixedly arranged at the center section of the driving gear, and one end of the adjustment rod rotates and passes through the bottom of the support seat and is fixedly arranged with a hand wheel.

[0013] In a possible design, the longitudinal adjustment assembly includes a screw rod fixedly arranged at one end of one of the rotating rods, the external thread of the screw rod is connected to a locking knob, and an adjustment knob is fixedly arranged at one end of the other rotating rod, a pointer is fixedly arranged on one side of the adjustment knob, and the support frame is located on one side of the adjustment knob and has a dial fixedly arranged thereon that can be used in conjunction with the pointer.

[0015] In a possible design, the bottoms of the three slide bars are all covered with anti-slip foot covers.

[0016] In the present application, when starting to use, first take out the measuring device from the storage state, and unfold the three support rods in the auxiliary assembly, and the three support rods are rotated to the required angle on the damping shaft from the connecting frame on the outside of the support seat, and then check whether the sliding rod is in the appropriate position. If the measuring height of the measuring instrument needs to be adjusted, first turn the locking handle so that the locking handle releases the limitation of the sliding rod position by the gasket, and then pull the sliding rod to make the sliding rod slide and extend in the sliding cavity of the support rod until it reaches the required length, and then turn the locking handle in the opposite direction, and use the locking handle to press against the gasket so that the gasket and the support rod are pressed against each other to fix the sliding rod in the required position, thereby preventing the sliding rod from sliding during use, and observe the bubble level on the top of the support frame when supporting and adjusting the height of the device. If the bubble is not in the center position, fine-tune the sliding rod in turn, and adjust the extending length of the sliding rod on the support rod until the bubble is in the center, thereby ensuring that the device is placed horizontally.

Then rotate the adjusting knob to drive the measuring instrument to rotate through the rotating rod. The rotation of the measuring instrument drives another rotating rod to rotate accordingly. Then observe the position of the pointer on the dial to ensure accurate adjustment of the angle. Then rotate the locking knob in the opposite direction so that the locking knob rotates on the screw rod until it abuts against one side of the support frame, thereby completing the adjustment of the longitudinal angle of the measuring instrument.

[0037] The auxiliary component is arranged on the support seat 1 and is used for supporting, folding, storing and raising the device. The auxiliary component includes three connecting frames fixedly arranged on the outer side of the support seat 1 in a ring shape. A damping shaft 2 is rotatably arranged on the inner side of each connecting frame. A support rod 3 is fixedly arranged on the outside of the three damping shafts 2. A sliding cavity is opened inside one end of the support rod 3, and a sliding rod 4 is slidably arranged inside the sliding cavity. A sliding groove connected to the sliding cavity is opened on one side of the three support rods 3. A connecting rod 5 is fixedly arranged on one end of the sliding cavity. The connecting rod 5 passes through the sliding groove and extends to the outside. A locking handle 7 is rotatably arranged on one end of the connecting rod 5 located outside the support rod 3. A gasket 6 is sleeved on the outside of the connecting rod 5 under the locking handle 7. When the device needs to be supported and raised, the three support rods 3 can be unfolded to support the device. If the height needs to be adjusted, the position of the sliding rod 4 in the sliding cavity is adjusted until the required height is reached. The sliding bar 4 is fixed in the desired position by the locking handle 7 and the gasket 6 to ensure the stability of the support rod 3. The locking handle 7 is moved to make it close to the support rod 3, and the friction force of the gasket 6 is used to fix the position of the sliding bar 4 to avoid sliding during use, thereby supporting and raising the device to provide stable support, ensuring that the measuring device will not shift or rotate during use, thereby ensuring the accuracy of the measurement results. At the same time, the height of the measuring device can be adjusted to adapt to the measurement needs of different heights, thereby improving the applicability and flexibility of the device. When not in use, the locking handle 7 is released, the sliding bar 4 is slid to the bottom of the support rod 3, and then the support rod 3 is rotated back into the connecting frame through the damping shaft 2 to complete the folding and storage of the device, so that the measuring device can be folded up when not in use, reducing the size and weight of the device, making it easy to carry and store, and at the same time effectively utilizing space and reducing the footprint of the device.

[0038] A lateral adjustment component is arranged on the support seat 1 and is used to adjust the lateral angle of the measuring instrument 13.

A driving gear 10 is rotatably arranged inside the upper part of the support seat 1, and the driving gear 10 is meshed with the driven gear 9 for transmission. An adjusting rod is fixedly arranged at the center section of the driving gear 10. One end of the adjusting rod rotates and passes through the bottom of the support seat 1 and is fixedly provided with a hand wheel 11. By rotating the hand wheel 11, the driving gear 10 can be driven to rotate. When the driving gear 10 rotates, the driven gear 9 is driven to rotate, and then the turntable 8 is driven to rotate through the driven gear 9, allowing the measuring instrument 13 to be adjusted in the horizontal direction. This enables the device to adapt to more diverse measurement needs. No matter what lateral position the workpiece or measurement target is in, it can be accurately aligned and measured. At the same time, it can ensure that the relative position between the measuring instrument 13 and the workpiece or measurement target is more accurate, thereby reducing the measurement error caused by angle deviation.

A dial 18 that can be used in conjunction with the pointer 17 is fixedly arranged on one side of the adjusting knob 16 of the support frame 12. By rotating the adjusting knob 16, the rotating rod can be driven to rotate, and then the longitudinal angle adjustment of the measuring instrument 13 is achieved through the cooperation of the screw rod 14 and the locking knob 15, and the angle is accurately read through the pointer 17 and the dial 18, so that the measuring instrument 13 can easily adapt to measurement targets of different heights or inclinations, so that the measuring device can cope with more diverse measurement needs, and at the same time, it can ensure that the relative position between the measuring instrument 13 and the workpiece or the measurement target is more accurate, thereby reducing the measurement error caused by the angle deviation and improving the accuracy of the measurement result.
