A circular plate 33 is rotatably connected to the inner wall of the fixed shell 31, and a through groove 1 38 is provided on the front surface of the circular plate 33. The through groove 1 38 has a certain inclination, ensuring that when the circular plate 33 is rotated, the slide bar 37 will move along its inclination. A groove 1 310 is provided on the right end of the front surface of the circular plate 33. There are multiple groups of grooves 1 310, which can cooperate with the pull rod 32 to ensure that wiper motors of different sizes can be stably clamped.

[0031] Reference Figure 2 - Figure 3 The locking assembly 5 includes an insertion rod 53, which is slidably connected to the right end of the front surface of the concave slider 4. The front surface of the insertion rod 53 is fixedly connected to an L-shaped connecting plate 52, and the rear surface of the top end of the L-shaped connecting plate 52 is threadedly connected to a bidirectional threaded rod 51. The bidirectional threaded rod 51 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. At the same time, it has the characteristic of axial self-locking to ensure the stability of the structural connection.

[0032] Reference Figure 1 There are multiple groups of concave sliders 4, and the multiple groups of concave sliders 4 slide on the left end of the upper surface of the slide rail 2. The upper surface of the multiple groups of concave sliders 4 is provided with connecting rod clamps 6. The connecting rod clamps 6 are prior art, which can fix the connecting rod of the wiper motor to ensure the stability of the test and can be implemented by technicians in this field. Since it is prior art, it will not be described in detail in this case.

[0033] Reference Figure 2 - Figure 3The fixing assembly 3 also includes a slide bar 37, which is slidably connected to the inner wall of the second through groove 39, and the outer wall of the front end of the slide bar 37 is slidably connected to the inner wall of the first through groove 38. The rear surface of the slide bar 37 is fixedly connected with a clamping block 34, and the inner wall of the clamping block 34 is slidably connected with a semicircular block 36. When the wiper motor contacts the semicircular block 36, it will rotate, and the wiper motor can be fixed at multiple points to ensure the stability of the wiper motor. The lower surface of the semicircular block 36 is made of rubber material, and the rubber material has a certain elasticity. When it contacts the wiper motor, it will deform, increasing the contact area and improving stability.

[0034] Reference Figure 1 - Figure 3 The fixing assembly 3 also includes a pull rod 32, which is slidably connected to the front surface of the fixing shell 31, and the rear end of the pull rod 32 contacts the inner wall of the groove 310. A spring 35 is sleeved on the outer wall of the pull rod 32. The spring 35 always pulls the pull rod 32 backward by its own elasticity to ensure the stability of the limit. One end of the spring 35 is fixedly connected to the front surface of the fixing shell 31, and the other end of the spring 35 is fixedly connected to the rear surface of the pull rod 32. The rear surface of the pull rod 32 is set as an inclined surface, and the set inclined surface enables the clamping block 34 to complete quick clamping.

[0035] Reference Figure 1 - Figure 3 A groove 27 is provided on the inner wall of the slide rail 2, and the rear end of the insertion rod 53 contacts the inner wall of the groove 27. The rear surface of the insertion rod 53 is set to an inclined surface. The set inclined surface can ensure that when the insertion rod 53 is inserted into the inner wall of the groove 27, the ball 56 enters the inner wall of the groove 3 8 to enhance stability. The inner wall of the groove 3 8 is elastically connected to the right cylinder 55 through the spring 2 54. The cylinder 55 is slidably connected to the inner wall of the groove 3 8. The spring 2 54 always pushes the concave slider 4 to move upward through its own elasticity, ensuring that the ball 56 can quickly break away from the inner wall of the groove 3 8. One end of the spring 2 54 is fixedly connected to the inner wall of the groove 3 8, and the other end of the spring 2 54 is fixedly connected to the upper surface of the cylinder 55. The lower surface of the cylinder 55 is rotatably connected with the ball 56. The ball 56 can reduce the stability of the concave slider 4 when it moves, and improve the smoothness of adjusting the concave slider 4.

[0036] Working principle: When the wiper motor needs to be fixed during use, the motor is placed in the middle of the multiple groups of clamping blocks 34, and then the circular plate 33 is rotated. At this time, the slide bar 37 will slide along the inner wall of the through groove 1 38 opened on the front surface of the circular plate 33, and at the same time, it will slide along the inner wall of the through groove 2 39 along the slope of the through groove 1 38 until the semicircular block 36 contacts the motor. The semicircular block 36 will rotate on the inner wall of the clamping block 34, so that the multiple groups of semicircular blocks 36 can fix the motor in multiple directions, thereby improving stability. When the circular plate 33 is rotated, the circular plate 33 will slide along the pull rod 3 2 pushes the pull rod 32 to move and disengage from the inner wall of the groove 310, and the pull rod 32 will stretch the spring 35 until the pull rod 32 overlaps with another set of grooves 310. At this time, the spring 35 will pull the pull rod 32 to reset through its own elasticity. After the motor is fixed, the connecting rod connected to the wiper motor is fixed by the connecting rod clamp 6, and then the test can be carried out. When dismantling, pull the pull rod 32 to disengage from the inner wall of the groove 310, and then reverse the circular plate 33 to release the fixation of the wiper motor. The subsequent structural matching method is the same as above.

[0037] When the distance between the connecting rod clamp 6 and the fixing assembly 3 needs to be adjusted, the bidirectional threaded rod 51 is rotated. At this time, the bidirectional threaded rod 51 threadedly connected to the outer wall of the bidirectional threaded rod 51 will move horizontally, and the L-shaped connecting plate 52 will drive the insertion rod 53 to move until the insertion rod 53 is separated from the inner wall of the groove 2 7 and does not contact the slide rail 2. At this time, the spring 2 54 will push the cylinder 55 and the ball 56 to move through its own elasticity, and lift the concave slider 4 through the elastic reaction force. At this time, the concave slider 4 is pushed, and the ball 56 will The upper surface of the slide rail 2 rolls, making the adjustment faster and smoother. When fixing, just reverse the bidirectional threaded rod 51, and the insertion rod 53 and the L-shaped connecting plate 52 will move in the opposite direction. At the same time, the slide rail 2 will drive the concave slider 4 to move in the opposite direction along the inclined surface of the insertion rod 53 until the insertion rod 53 is inserted into the inner wall of the groove 2 7, and the fixation is completed. In this process, the ball 56 will be squeezed, and the squeezing force will act on the cylinder 55. The cylinder 55 will enter the inner wall of the groove 3 8 and squeeze the spring 2 54, making the fixation more stable.
