In summary, the beneficial effects of the utility model are:

In the utility model, the measuring instrument is generally placed on the measuring instrument bracket for measurement. The traditional measuring instrument bracket is generally a tripod bracket, and the three support rods can be telescopically adjusted. However, if only the height in the vertical direction is to be adjusted, the three support rods must be adjusted, which leads to cumbersome operation. Therefore, when the height of the measuring instrument needs to be adjusted in the vertical direction, the adjusting rod is moved to slide in the adjusting hole on one side of the fixing plate, and at the same time, two positioning strips fixed on the inner wall of the adjusting hole slide in the two positioning grooves on the arc surface of the adjusting rod respectively, thereby preventing the adjusting rod from deflecting when sliding on the inner wall of the adjusting hole, and the movement of the adjusting rod drives the movement of the mounting plate, and the movement of the mounting plate drives the movement of the measuring instrument. When the height of the measuring instrument is moved After moving into place, the screw rods on the inner walls of the two connecting plates are driven to rotate by rotating the turntable. The arc surface of the turntable is provided with anti-skid patterns. The anti-skid patterns can increase the friction between the personnel's hands and the arc surface of the turntable, so that the personnel can rotate the turntable more stably. The two clamping rings are driven to move by the rotation of the screw rod. Because the arc surface of the screw rod is provided with two reverse threads, the two clamping rings move closer to or away from each other. At the same time, the two clamping rings move on the arc surface of the limit rod. The limit rod can prevent the two clamping rings from deflecting during the movement. The adjusting rod is clamped and fixed by the movement of the two clamping rings closer to each other. Through the operation of the adjusting structure, the effect of conveniently and directly adjusting the vertical height of the measuring instrument when in use is achieved.

In the utility model, the measuring instrument is generally used in conjunction with a tripod bracket, so when the measuring instrument needs to be installed and fixed, the connecting plate is driven to move away from the center of the mounting plate by pulling the pull ring, and the spring on the welding plate is compressed by the movement of the connecting plate. The spring is stretched or compressed on the arc surface of the telescopic rod, thereby preventing the spring from deforming during the stretching or compression process. The movement of the connecting plate drives the movement of the plug rod. When the four plug rods are moved into place, the bottom plate at the lower end of the measuring instrument is placed into the ring formed by the four auxiliary plates and fits with the inner walls of the four auxiliary plates and is placed on the surface of the mounting plate. When the bottom plate is in place, it is released. The pull ring drives the connecting plate and the plug rod to automatically move back through the rebound force of the spring, and the plug rod is automatically moved back and inserted into the fixed groove on the arc surface of the bottom plate. A guide block is fixed at one end of the plug rod. Because the guide block is conical, it is convenient for the plug rod to be quickly and accurately inserted into the fixed groove. The connecting plate will automatically move back between the two auxiliary plates. At the same time, the limit blocks on both sides of the connecting plate will be inserted into the limit grooves on the sides of the auxiliary plate accordingly, thereby avoiding the upward and downward position deviation of the connecting plate and the plug rod, so that the measuring instrument can be quickly installed and fixed on the mounting plate. Through the operation of the auxiliary structure, the effect of facilitating the rapid installation and disassembly of the measuring instrument and the tripod bracket is achieved.

Detailed explanation of usage: In the present invention, the measuring instrument 6 is generally placed on the measuring instrument 6 bracket for measurement. The traditional measuring instrument 6 bracket is generally a triangular bracket, and the three support rods 1 can be telescopically adjusted. However, if only the vertical height is to be adjusted, the three support rods 1 must be adjusted, which makes the operation cumbersome. Therefore, when the height of the measuring instrument 6 needs to be adjusted in the vertical direction, the adjusting rod 302 is moved to slide in the adjusting hole 301 on one side of the fixing plate 2, and at the same time, the two positioning strips 308 fixed on the inner wall of the adjusting hole 301 slide in the two positioning grooves 309 on the arc surface of the adjusting rod 302 respectively, thereby preventing the adjusting rod 302 from deflecting when sliding on the inner wall of the adjusting hole 301, and the movement of the adjusting rod 302 drives the movement of the mounting plate 5, and the movement of the mounting plate 5 drives the movement of the measuring instrument 6. When the height of the measuring instrument 6 is moved into place, The rotating disk 305 drives the screw rod 304 on the inner wall of the two connecting plates 303 to rotate. The arc surface of the rotating disk 305 is provided with anti-skid patterns 310. The anti-skid patterns 310 can increase the friction between the personnel's hands and the arc surface of the rotating disk 305, so that the personnel can rotate the rotating disk 305 more stably. The rotation of the screw rod 304 drives the movement of the two clamping rings 306. Because the arc surface of the screw rod 304 is provided with two reverse threads, the two clamping rings 306 move closer to or away from each other. At the same time, the two clamping rings 306 move on the arc surface of the limiting rod 307. The limiting rod 307 can prevent the two clamping rings 306 from deflecting during the movement. The adjusting rod 302 is clamped and fixed by the movement of the two clamping rings 306 closer to each other. By operating the adjusting structure 3, the measuring instrument 6 can be conveniently and directly adjusted in the vertical direction when in use.

In the present invention, the measuring instrument 6 is generally used in conjunction with a tripod bracket. Therefore, when the measuring instrument 6 needs to be installed and fixed, the connecting plate 403 is driven to move away from the center of the mounting plate 5 by pulling the pull ring 408. The movement of the connecting plate 403 drives the spring 402 on the welding plate 401 to be compressed. The spring 402 is sleeved on the arc surface of the telescopic rod 411 for stretching or compression. This can prevent the spring 402 from deforming during the stretching or compression process. The movement of the connecting plate 403 drives the movement of the plug rod 404. When the four plug rods 404 are moved into place, the bottom plate 409 at the lower end of the measuring instrument 6 is placed into the ring formed by the four auxiliary plates 406 and fits with the inner walls of the four auxiliary plates 406 and is placed on the surface of the mounting plate 5. When the bottom plate 409 is in place, the pull ring 408 is released. The rebound force of the spring 402 drives the connecting plate 403 and the insertion rod 404 to automatically move back, and the insertion rod 404 is automatically moved back and inserted into the fixed groove 410 on the arc surface of the bottom plate 409. A guide block 412 is fixed to one end of the insertion rod 404. Because the guide block 412 is conical, it is convenient for the insertion rod 404 to be quickly and accurately inserted into the fixed groove 410, and the connecting plate 403 will automatically move back between the two auxiliary plates 406. At the same time, the limit blocks 405 on both sides of the connecting plate 403 will be correspondingly inserted into the limit grooves 407 on the sides of the auxiliary plate 406. This can avoid the upward and downward position deviation of the connecting plate 403 and the insertion rod 404, so that the measuring instrument 6 can be quickly installed and fixed on the mounting plate 5. By operating the auxiliary structure 4, the effect of facilitating the rapid installation and disassembly of the measuring instrument 6 and the tripod bracket is achieved.
