[0042] Example 2
[0043] Reference Figures 1 to 8 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.
[0044] Specifically, the protective member 203 includes a support column 203a and a support rod 203b. The support column 203a is fixed in the support platform 201a, and the support rod 203b is fixed to the top of the support column 203a.

[0050] Example 3
[0051] Reference Figures 1 to 8 , which is the third embodiment of the present utility model, and is based on the first two embodiments.
[0052] Specifically, the protective part 203 also includes an extrusion spring 203g, a limiting column 203h and a wire tube 203i. The extrusion spring 203g is sleeved on the surface of the sliding rod 203e, the limiting column 203h is fixed on the top of the support bar 203d, the wire tube 203i is arranged in the test bench 101, and a pressing groove U is opened on the top of the support bar 203d, and a slot V is opened on one side of the support platform 201a and the support shell 201b.
[0053] The extrusion spring 203g is in a compressed state. The return elastic force of the extrusion spring 203g can make the extrusion block 203f move toward the support bar 203d, thereby pressing the connecting wire into the pressing groove U. The limiting column 203h is used to limit the position of the connecting wire so that the connecting wire is always located in the pressing groove U. The wire tube 203i is used to lead out various connecting wires of the test bench 101, so that the connecting wire can be better set on the top of the support bar 203d. The setting of the notch V can prevent the support platform 201a and the support shell 201b from squeezing the connecting wire during the lifting process.
[0054] Specifically, the release member 204 includes a pull rod 204a and a driving column 204b. The pull rod 204a is fixed to the bottom of the support bar 203d, and the driving column 204b slides in the pull rod 204a.
[0055] The pull rod 204a is used to pull the support bar 203d downward so that the support bar 203d is away from the support rod 203b, and the driving column 204b is used to drive the pull rod 204a to move downward.
[0056] Specifically, the release member 204 also includes a lifting rod 204c, a limit block 204d and a positioning sleeve 204e. The lifting rod 204c is fixed to one side of the driving column 204b, the limit block 204d is fixed to the bottom of the lifting rod 204c, the positioning sleeve 204e is fixed in the test bench 101, and the limit block 204d slides in the positioning sleeve 204e.
[0057] The lifting rod 204c is used to drive the driving column 204b to move downward, the limit block 204d is used to limit the position of the lifting rod 204c, and the positioning sleeve 204e is used to limit the positions of the lifting rod 204c and the limit block 204d, so that the lifting rod 204c can be lifted and lowered stably. Before the support platform 201a rises to the top of its stroke, the limit block 204d first rises to the top of its stroke in the positioning sleeve 204e. At this time, the support platform 201a continues to rise, which will cause the limit block 204d to pull the driving column 204b through the lifting rod 204c, so that the driving column 204b pulls the pull rod 204a, so that the pull rod 204a moves downward relative to the support platform 201a. At this time, the support bar 203d is away from the support rod 203b, reducing the extrusion force of the extrusion block 203f on the connecting line, making it easier for the staff to operate the connecting line.
[0058] When in use, before testing the charger, first connect the connecting wire and the charger 202, and then start the cylinder 201d, so that the support platform 201a drives the charger 202 to move downward. At this time, under the action of the return elastic force of the support spring 203c, the support bar 203d can be moved toward the support rod 203b, thereby increasing the extrusion force of the extrusion spring 203g on the support rod 203b on the extrusion block 203f, making the extrusion block 203f clamp the connecting wire more powerful, preventing the connecting wire and the support bar 203d from moving relative to each other during the lifting and lowering of the support platform 201a, ensuring the stability of the connecting wire. When the support shell 201b falls above the support plate 201e, the output end of the cylinder 201d stops moving. At this time, the charger 202 is in the test bench 101, so that the staff will not touch the connecting wire. At this time, the test bench 101 can be started to test the charger 202.
[0059] When the inspection is completed, the output end of the cylinder 201d drives the support platform 201a to rise and reset. During this process, before the support platform 201a rises to the top of its stroke, the limit block 204d first rises to the top of its stroke in the positioning sleeve 204e. At this time, the support platform 201a continues to rise, which will cause the limit block 204d to pull the drive column 204b through the lifting rod 204c, so that the drive column 204b pulls the pull rod 204a, causing the pull rod 204a to move downward relative to the support platform 201a. At this time, the support bar 203d is away from the support rod 203b, reducing the extrusion force of the extrusion block 203f on the connecting line, making it easier for the staff to operate the connecting line.
[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
