[0008] Preferably, the first current needle rod, the second current needle rod, and the connecting rod are coaxial with each other, and a voltage line is provided between the first current needle rod and the second current needle rod. The voltage line is horizontally located inside the connecting rod, and both ends of the voltage line are welded and communicated with the first voltage needle rod and the second voltage needle rod respectively.
[0009] Preferably, a second compression spring is elastically provided between the second voltage needle rod and the second current needle rod, and the second compression spring is sleeved outside the second voltage needle rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the mounting body is clamped to one side inside the battery tray, the two sides of the mounting body are in contact with the airbags inside the battery tray, and the surfaces on both sides of the mounting body withstand the pressure exerted by the airbags. At this time, the probe on the external device will push the first probe on one side of the mounting body, and the first probe drives the connecting rod to move inside the mounting body, and one side of the connecting rod drives the second probe to move, so that the second probe moves to the battery terminal of the battery on the other side of the battery tray and makes contact and conductive connection with the battery terminal, thereby performing charge and discharge tests on the battery. Conversely, when the charge and discharge test of the battery is completed, the probe on the external device moves away from the side of the first probe. At this time, the second probe rebounds and resets through the first compression spring, and the second probe is separated from the battery terminal, thereby driving the connecting rod to move and reset and at the same time pushing the first probe to move and reset. When there is no airbag inside the battery tray, the mounting body can remove the box surfaces on both sides, thereby forming a skeleton-type probe adapter. Therefore, when the size of the battery in the tray is shorter than the size set by the tray, there is no need to make a corresponding tray. With this probe adapter, the probe on the device can be connected to the battery in the tray to achieve the effect of transfer and conduction.

Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0028] Please refer to Figures 1 - 10, in the embodiments of the present utility model, a probe adapter includes a mounting body 1, and the mounting body 1 can be either a box body or a fixing bracket, and the fixing bracket can be of an integrally formed type or a split locking combination type. A first current needle rod 2 is horizontally arranged on one side of the mounting body 1, and the first current needle rod 2 penetrates through the side surface of the mounting body 1. A first current needle head 16 is formed on one side of the first current needle rod 2. A connecting rod 5 is horizontally arranged on the other side of the first current needle rod 2, and the connecting rod 5 is horizontally located inside the mounting body 1, and one end of the connecting rod 5 is fixedly connected to the first current needle rod 2. A second current needle rod 6 is horizontally arranged on the other side of the mounting body 1, and the second current needle rod 6 penetrates through the other side surface of the mounting body 1, and the other end of the connecting rod 5 is fixedly connected to the second current needle rod 6.
[0029] A groove 17 is formed on one side of the first current needle head 16, and the groove 17 communicates with the first current needle rod 2. A first voltage needle rod 18 is horizontally arranged inside the groove 17. A first voltage needle head 9 is vertically formed on one side of the first voltage needle rod 18, and the first voltage needle head 9 is vertically fixed inside the groove 17 and is welded between the first voltage needle rod 18 and a voltage wire 11. A first insulating member 10 is arranged between the first voltage needle head 9 and the groove 17, and the first insulating member 10 is inserted into the groove 17. The first voltage needle head 9 is vertically attached to the side surface of the first insulating member 10, and the first voltage needle rod 18 is horizontally riveted to the first insulating member 10. Thus, the first insulating member 10 semi - surrounds the first voltage needle head 9 and fixes the first voltage needle rod 18 to the side of the first current needle head 16 together. Thus, a first probe is formed by the first current needle rod 2, the first voltage needle rod 18 and the first voltage needle head 9 arranged on the first current needle head 16, and the first probe is in contact and communication with the probe on an external device.
[0030] A second insulating member 3 is arranged between the second current needle rod 6 and the mounting body 1, and the second insulating member 3 is vertically located on one side outside the mounting body 1. One end of the second current needle rod 6 penetrates through the mounting body 1 and is elastically movable inside the second insulating member 3. A second current needle head 20 is vertically arranged on one side of the second insulating member 3, and a second voltage needle head 4 is vertically arranged on one side of the second current needle head 20. A fifth insulating member 19 is arranged between the second current needle head 20 and the second voltage needle head 4. Thus, the second voltage needle head 4 is movably sleeved on the second current needle head 20 through the fifth insulating member 19, and the swinging angle of the second current needle head 20 is limited by the second insulating member 3. Thus, when the second current needle rod 6 is inside the second insulating member 3, the space between the second current needle rod 6 and the second current needle head 20 can be adjusted to have a gap or no gap according to the actual use situation.
[0031] The second current needle rod 6 is provided with a second voltage needle rod 12. The second voltage needle rod 12 is elastically disposed transversely inside the second current needle rod 6 and is welded to the voltage wire 11. The other end of the second voltage needle rod 12 is elastically located on one side outside the second current needle rod 6. The second voltage needle rod 12 is aligned with the second voltage needle head 4. The second voltage needle rod 12 and the second voltage needle head 4 are elastically abutted, and the second current needle rod 6 and the second current needle head 20 are buckled through the second insulating member 3. The second current needle head 20 and the second voltage needle head 4 are movably sleeved through the fifth insulating member 19. The second current needle rod 6 and the second current needle head 20 are inserted into each other in a concave-convex manner. Thus, the second current needle head 20 and the second voltage needle head 4 form a universal joint. Further, the second current needle rod 6, the second current needle head 20, the second insulating member 3, the second voltage needle rod 12, and the second voltage needle head 4 are combined to form a second probe. When the second voltage needle rod 12 elastically presses against the second voltage needle head 4 and the second probe together with the universal joint presses against the battery pole column, the second current needle head 20 will automatically swing the angle according to the surface of the pole column, so that its end surface completely fits the surface of the pole column and has the best conduction effect with the battery pole column. And through this mechanism, it can be applied to the composition of various probes.
[0032] The first current needle rod 2, the second current needle rod 6, and the connecting rod 5 are coaxial with each other. A voltage wire 11 is provided between the first current needle rod 2 and the second current needle rod 6. The voltage wire 11 is transversely located inside the connecting rod 5, and both ends of the voltage wire 11 are welded and communicated with the first voltage needle rod 18 and the second voltage needle rod 12 respectively.
[0033] A second compression spring 14 is elastically disposed between the second voltage needle rod 12 and the second current rod 6. The second compression spring 14 is sleeved outside the second voltage needle rod 12. One end of the second compression spring 14 is elastically connected to one side outside the second voltage needle rod 12. Further, the second compression spring 14 enables the second voltage needle rod 12 to perform axial elastic movement inside the second current needle rod 6, so that the second voltage needle rod 12 and the second voltage needle head 4 are elastically abutted.
[0034] A third insulating member 13 and a fourth insulating member 15 are provided between the second current needle rod 6 and the second voltage needle rod 12. The third insulating member 13 is located on one side outside the second current needle rod 6, and the second voltage needle rod 12 penetrates through the third insulating member 13. The fourth insulating member 15 is located on one side inside the second current needle rod 6, and the second voltage needle rod 12 penetrates through the fourth insulating member 15. The second voltage needle rod 12 elastically moves at the middle position of the fourth insulating member 15.
[0035] A probe swing limiting hole 8 is provided between the second insulating member 3 and the mounting body 1, and the probe swing limiting hole 8 is formed at one side outside the mounting body 1. The probe swing limiting hole 8 penetrates the side surface of the outside of the mounting body 1, and one side of the second insulating member 3 penetrates the probe swing limiting hole 8. Thus, through the cooperation between the probe swing limiting hole 8 and the second insulating member 3, the angular limit when the second current needle head 20 swings is achieved.
[0036] A first compression spring 7 is sleeved outside the second current needle rod 6. One end of the first compression spring 7 is connected to the second current needle rod 6, and the other end of the first compression spring 7 is connected to the inner side surface of the mounting body 1. Thus, through the first compression spring 7, the second current needle rod 6 can perform elastic movement at the other side of the mounting body 1. The connecting rod 5 locks the first current needle rod 2 and the second current needle rod 6 into one body. Thus, the connecting rod 5, the first probe, and the second probe can perform elastic movement together. When the mounting body 1 is clamped to one side inside the battery tray, the two sides of the mounting body 1 are abutted against the air bags inside the battery tray, and the surfaces of the two sides of the mounting body 1 withstand the pressure given by the air bags. At this time, the probe on the external device will push the first probe, and the first probe drives the connecting rod 5 to move into the mounting body 1, and one side of the connecting rod 5 drives the second probe to move. Thus, the second probe moves to the battery pole column of the battery on the other side of the battery tray and makes contact and conductive connection with the battery pole column, and thus the battery is subjected to charge and discharge testing. On the contrary, after the battery charge and discharge testing is completed, the probe on the external device moves away from the side of the first probe. At this time, the second probe rebounds and resets through the first compression spring 7, and the second probe is separated from the battery pole column, thereby driving the connecting rod 5 to move and reset and at the same time pushing the first probe to reset. When there is no air bag inside the battery tray, the two side box surfaces of the mounting body 1 can be removed to form a framework type probe adapter. Thus, when the size of the battery in the tray is shorter than the size set for the tray, there is no need to make a corresponding tray. With this probe adapter, the probe on the device can be connected to the battery in the tray to achieve the effect of transfer and conduction.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
