[0033] In order to further optimize the above technical solution, the transverse threaded rod 51 and the longitudinal threaded rod 52 are provided with a first threaded portion 511 and a second threaded portion 512 with opposite thread directions.

[0034] To further optimize the above technical solution, the driving device 6 includes: a driving motor 61, a driving rod 62, and an active bevel gear 63. The driving motor 61 is installed on the base 1 through a fixed bracket 611. Two driving motors 61 are provided, corresponding to the transverse threaded rod 51 and the longitudinal threaded rod 52 respectively. The output end of the driving motor 61 is fixedly connected with the driving rod 62. A fixing plate 621 is provided on the base 1. The driving rod 62 passes through the fixing plate 621 and is rotatably connected to the fixing plate 621. The driving rod 62 installed on the driving motor 61 corresponding to the transverse threaded rod 51 is vertically arranged with the transverse threaded rod 51, and the driving rod 62 installed on the driving motor 61 corresponding to the longitudinal threaded rod 52 is vertically arranged with the longitudinal threaded rod 52.

[0035] Specifically, a fixing plate 621 is provided, and a driving rod 62 passes through the fixing plate 621 and is rotatably connected to the fixing plate 621. The fixing plate 621 supports the driving rod 62, and a driving motor 61 and a driving rod 62 are respectively provided corresponding to the transverse threaded rod 51 and the longitudinal threaded rod 52, which can respectively control the rotation of the transverse threaded rod 51 and the longitudinal threaded rod 52.

[0036] In order to further optimize the above technical solution, a driving bevel gear 63 is provided on the driving rod 62 corresponding to the driven bevel gear 53 , and the driving bevel gear 63 is meshedly connected with the driven bevel gear 53 .

[0037] Specifically, the driven bevel gear 53 on the driving rod 62 is arranged corresponding to the active bevel gear 63, and two active bevel gears 63 are arranged on each driving rod 62, so that one driving rod 62 can simultaneously control the rotation of two transverse threaded rods 51 or two longitudinal threaded rods 52, and one driving rod 62 only corresponds to one driving motor 61, which saves the utilization of resources.

[0038] In order to further optimize the above technical solution, a movable block 72 is provided at one end of the L-shaped adjustment fixing rod 7, and the movable block 72 is threadedly connected to the threaded rod 5. Two L-shaped adjustment fixing rods 7 are respectively arranged on each threaded rod 5, and the two L-shaped adjustment fixing rods 7 are respectively arranged on the first threaded portion 511 and the second threaded portion 512 of the threaded rod 5.

[0039] Specifically, the L-shaped adjustment fixing rod 7 is respectively arranged on the first threaded portion 511 and the second threaded portion 512 with opposite thread directions on the threaded rod 5. When the threaded rod 5 rotates, the L-shaped adjustment fixing rod 7 relatively arranged on the threaded rod 5 can move in relative or opposite directions at the same time, so that it can fix both sides of the vibrometer 3.

[0040] In order to further optimize the above technical solution, a through groove 41 is provided on the mounting plate 4 corresponding to the L-shaped adjusting fixing rod 7 for its passage, and a sliding block 73 is provided at the position of the L-shaped adjusting fixing rod 7 corresponding to the through groove 41. The sliding block 73 is slidably connected to the through groove 41. The other end of the L-shaped adjusting fixing rod 7 passes through the fixing frame 2 and extends into the fixing frame 2, and contacts the vibrometer 3 through the shock-absorbing rubber pad 71.

[0041] Specifically, a through groove 41 is provided on the mounting plate 4 corresponding to the L-shaped adjusting fixing rod 7 so that the L-shaped adjusting fixing rod 7 can pass through when moving, and will not block the movement of the L-shaped adjusting fixing rod 7. A sliding block 73 is provided on the L-shaped adjusting fixing rod 7 at a position corresponding to the through groove 41. When the moving block 72 of the L-shaped adjusting fixing rod 7 moves when the threaded rod 5 rotates, the sliding block 73 is provided in the through groove 41. When the sliding block 73 slides in the through groove 41, the through groove 41 restricts the sliding block 73, preventing the moving block 72 of the L-shaped adjusting fixing rod 7 from rotating along with the rotation of the threaded rod 5, so that the L-shaped adjusting fixing rod 7 can move along with the rotation of the threaded rod 5.

[0042] Working principle: before starting the vibrometer 3, first place the vibrometer 3 in the fixed frame 2, start the drive motor 61, and the drive motor 61 rotates to drive the drive rod 62 to rotate. The fixed plate 621 supports the drive rod 62, and the active bevel gear 63 on the drive rod 62 arranged perpendicular to the transverse threaded rod 51 drives the driven bevel gear 53 on the transverse threaded rod 51 to rotate, thereby driving the transverse threaded rod 51 to rotate. Since the sliding block 73 arranged on the L-shaped adjustment fixing rod 7 is slidably connected with the through groove 41 on the mounting plate 4, the through groove 41 restricts the sliding block 73, so that the L-shaped adjustment fixing rod 7 will not rotate due to the rotation of the threaded rod 5. When the transverse threaded rod 51 rotates, the L-shaped adjustment fixing rod arranged on the transverse threaded rod 51 The moving block 72 at the end of 7 moves relative to the transverse threaded rod 51. Since the L-shaped adjusting and fixing rod 7 is respectively arranged on the first threaded portion 511 and the second threaded portion 512 of the threaded rod 5, the L-shaped adjusting and fixing rod 7 moves relatively on the transverse threaded rod 51, exerts a relative force on the vibrator 3, and fixes the vibrator 3 in the left and right directions. At the same time, under the action of the driving motor, the driving rod 62 arranged perpendicular to the longitudinal threaded rod 52 drives the longitudinal threaded rod 52 to rotate, so that the L-shaped adjusting and fixing rod 7 on the longitudinal threaded rod 52 moves relatively, and fixes the vibrator 3 in the front and back directions. After observing that the shock-absorbing rubber pads 71 ​​on each L-shaped adjusting and fixing rod 7 are in conflict with the vibrator 3, the driving motor 61 is turned off to complete the fixation of the vibrator 3.

[0043] The beneficial effect of this embodiment is that by respectively arranging the transverse threaded rod and the longitudinal threaded rod around the fixed frame, and the transverse threaded rod and the longitudinal threaded rod are provided with two L-shaped adjustment fixing rods, the threaded rod can be driven to rotate by the driving device, thereby driving the relatively arranged L-shaped adjustment fixing rod to move toward the direction of the pendulum meter. Since the pendulum meter is surrounded by L-shaped adjustment fixing rods, and the relatively arranged L-shaped adjustment fixing rods can apply relative force to the pendulum meter, the pendulum meter is fixed in the fixed frame. By setting multiple L-shaped adjustment fixing rods to apply force around the pendulum meter and fix the pendulum meter, it can prevent the pendulum meter from vibrating after it is started and prevent the pendulum meter from moving relative to the ground.
