[0014] 3、It can also be arranged with horizontal rods of different positions, so as to realize contact in different directions of the inductor element.

[0015] In some embodiments, the carrier base is provided with a rocker, the middle part of the rocker is connected with the carrier base bearing, one end of the rocker is provided with a slide column capable of sliding on the cross bar, the base is provided with a lifting cylinder, the lifting cylinder is drivingly connected with a lifting rod, the lifting rod is connected with the other end of the rocker in an axial manner, so that after the cross bar extends into the two sensor elements on the back of the touch button panel, the lifting cylinder drives the lifting rod to swing, the rocker drives the slide column to press down the cross bar to drive the probe to press down and contact the sensor element;

[0016] According to the technical scheme, the application further realizes the following beneficial effects:

[0017] 1. After the cross bar extends into the two sensor elements on the back of the touch button panel, the cross bar can be pressed down to drive the probe to press down and contact the sensor element through a mechanical mechanism.

[0018] 2. Since the slide column can slide on the cross bar, the slide column used for pressing down the cross bar will not block the movement of the cross bar.

[0019] In some embodiments, the carrier base is provided with a positive magnet and a negative magnet, the cross bar is provided with a passive magnet, when the cross bar extends into the two sensor elements on the back of the touch button panel, the passive magnet is away from the negative magnet and above the positive magnet, at this time, the positive magnet drives the cross bar to descend by attracting the passive magnet, so that the cross bar drives the probe to press down and contact the sensor element, during the movement of the cross bar out of the two sensor elements on the back of the touch button panel, the passive magnet is away from the positive magnet and close to the negative magnet, at this time, the negative magnet repels the passive magnet to gradually push the cross bar to rise, and the probe gradually moves away from the sensor element.

[0024] 4. By setting up a negative magnet, as the crossbar moves between the two sensor elements on the back of the touch button panel, the passive magnet moves away from the positive magnet and closer to the negative magnet. At this time, the negative magnet will repel the passive magnet, pushing the crossbar to gradually rise. The probe also gradually moves away from the sensor element. Thus, the rising speed of the crossbar is controlled by the cooperation of the positive and negative magnets, avoiding the crossbar from rising too fast and damaging the sensor element above it.

[0025] 5. Due to the ability to compress the repulsive reaction of the magnet, the interaction between the positive and negative magnets can buffer and slow down the return and downward stroke of the crossbar, thereby achieving slow and gradual lifting and lowering.

[0026] 6. By using a negative magnet, the crossbar can be supported by the repulsive force of the negative magnet against the passive magnet, thus eliminating the need for a support spring.

[0031] In some embodiments, the carrier plate is equipped with a buffer spring that pushes the product fixing block into the product slot to clamp and fix the touch button panel.

[0032] According to the technical solution, when the horizontal push cylinder drives the horizontal moving seat to move the product fixing block into the product slot, the elastic force of the buffer spring can push the product fixing block to press and fix the side of the touch button panel, thereby avoiding the excessive pushing force of the horizontal push cylinder from causing damage to the touch button panel.

[0065] To further illustrate the needle-feeding testing mechanism for use in confined spaces described in this specific embodiment, the following examples are provided.

[0066] Example 1

[0067] like Figures 1 to 9 As shown, this embodiment provides a needle-dropping testing mechanism for use in confined spaces, which includes a base 1, a carrier plate seat 2, a ribbon cable support platform, and a lifting cylinder 52.

At this time, the ribbon cable support is used to support the ribbon cable. The carrier plate base 2 is equipped with a horizontal push cylinder 3, which is driven by a horizontal sliding seat 31.

[0069] The transverse sliding seat 31 is equipped with a product fixing block 32, and the product fixing block 32 is equipped with a support block 33.

The carrier plate seat 2 is equipped with a buffer spring 34 to push the product fixing block 32 into the product groove 21 to clamp and fix the touch button panel 6.

[0070] The product fixing block 32 is equipped with a support spring 41, which supports a horizontal bar 4 that can float vertically up and down. The horizontal bar 4 can float vertically up and down on the product fixing block 32 by means of the cooperation of the guide shaft and the bushing.

[0072] Before the cross bar 4 moves out of the two sensor elements 61 on the back of the touch button panel 6, the lift cylinder 52 drives the top rod 53 to reverse swing the rocker 5, the rocker 5 drives the slide column 51 to rise to stop pressing down the cross bar 4, at this time, the elastic force of the supporting spring 41 pushes the cross bar 4 to reset and rise to drive the probe 42 to move away from the sensor elements 61. At the same time, the lift cylinder 52 controls the driving speed of the top rod 53 to swing, so that the slide column 51 can limit the reset rising speed of the cross bar 4, until the cross bar 4 moves out of the two sensor elements 61 on the back of the touch button panel 6, the cross bar 4 is completely reset to the initial position, so as to avoid the cross bar 4 rising too fast to hit and damage the sensor elements 61 above it and rub and damage the sensor elements 61 above it.

In this process, the passive magnet is away from the positive magnet and close to the negative magnet. At this time, the negative magnet repels the passive magnet to drive the horizontal rod 4 to gradually rise, and the probe 42 gradually moves away from the inductor elements 61.
