Detailed Description

The following is further illustrated by the specific embodiments:

reference numerals in the drawings of the specification include:

the test device comprises a handheld portion 1, a connector 2, a first test probe 3 with a conical head, a first test probe 4 with a spherical head, a first spring 5, a second spring 6, a connector 7, a connecting sleeve 8, a second test probe 9, a sliding block 10, a first sliding groove 11, a second sliding groove 12, a protrusion 13, a reset spring 14 and a sawtooth-shaped sliding groove 15.

The first embodiment is as follows:

as shown in fig. 1 and 2, a double-ended probe device includes a testing portion and a handheld portion 1, where the handheld portion 1 is a cylinder having a through hole, the through hole of the cylinder is used to accommodate other components, the testing portion is a first testing portion and a second testing portion, the first testing portion is disposed at the left end of the handheld portion 1, the second testing portion is disposed at the right end of the handheld portion 1, the first testing portion includes a connector 2 and at least two first testing probes, and in this embodiment, the two second testing probes are specifically described. According to the difference of syringe needle shape, two first test probe are spherical first test probe 4 and conical head first test probe 3 respectively, and the syringe needle sets up to conical first test probe and is applicable to the more smooth and flat product of test surface, and the syringe needle sets up to spherical first test probe and is applicable to the product of test surface unevenness.

The first testing part further comprises two groups of sliding assemblies, each group of sliding assemblies comprises a sliding block 10 and a first sliding groove 11, the first sliding groove 11 is in an 'I' shape, the sliding block 10 can move in the first sliding groove 11, the first testing probe 4 of the spherical head and the first testing probe 3 of the conical head are fixedly connected with the sliding block 10 respectively, the first sliding groove 11 is in an 'I' shape and is divided into a longitudinal part and a transverse part, when the sliding block 10 connected with the first testing probe 3 of the conical head is located at the longitudinal part of the first sliding groove 11, the first testing probe is located at a free probe and can move along with the sliding block 10, and when the sliding block 10 connected with the first testing probe 3 of the conical head is located at the transverse part of the first sliding groove 11, the position of the first testing probe 3 of the conical head is fixed, and axial movement cannot occur.

Because first spout 11 has two horizontal portions, when slider 10 is in the horizontal portion of the first spout 11 that is close to handheld portion 1 tail end, at this moment, the syringe needle of the first test probe of cone 3 stretches out connector 2, can use the device to carry out the product test, when slider 10 is in the horizontal portion of the first spout 11 of keeping away from handheld portion 1 tail end, at this moment, the syringe needle of the first test probe of cone 3 is located inside connector 2, directly expose in the air not, the first test probe of cone 3 is in idle state, connector 2 can avoid the syringe needle of the first test probe of cone 3 to receive wearing and tearing.

The operation of the ball-head second test probe 9 is the same.

The second test portion includes adapter sleeve 8 and second test probe 9, the afterbody of second test probe 9 is fixed in adapter sleeve 8, adapter sleeve 8 sets up in handheld portion 1, it has second spout 12 to open in handheld portion 1 outside, second spout 12 is "worker" shape, be equipped with a arch 13 on the adapter sleeve 8, this arch 13 passes second spout 12, and can move in second spout 12, because adapter sleeve 8 is in the jack-through of handheld portion 1, arch 13 is when second spout 12 internal motion, adapter sleeve 8 drives second test probe 9 and moves together.

Because the second chute 12 has two transverse parts, when the protrusion 13 is at the transverse part of the second chute 12 close to the tail end of the handheld part 1, at this time, the needle head of the second test probe 9 extends out of the connector 2, a product test can be performed by using the device, when the slider 10 is at the transverse part of the second chute 12 far away from the tail end of the handheld part 1, at this time, the needle head connecting sleeve 8 of the second test probe 9 is inside, and is not directly exposed in the air, and the second test probe 9 is in an idle state, so that the needle head of the second test probe 9 can be protected from being worn.

As shown in fig. 3 and 4, the connector 2 and the handheld portion 1 are connected through threads, so that the connector 2 is convenient to detach, the first test probe is convenient to maintain or replace, a connecting body 7 is arranged in the middle of the handheld portion 1 and used for connecting the first test probe and the second test probe 9, the connecting body 7 is a conductor, the first test probe 3 with a conical head and the first test probe 4 with a spherical head are both connected with a first spring 5, the first spring 5 is connected with the left side of the connecting body 7, the tail of the second test probe 9 is connected with a second spring 6, and the second spring 6 is connected with the right side of the connecting body 7.

In addition, connector 2, handheld portion 1 and adapter sleeve 8 are the insulators, prevent to cause the injury to the human body.

Example two:

as shown in fig. 5 and 6, the present embodiment is different from the first embodiment in that the second sliding slot is configured as a sawtooth sliding slot 15, the protrusion 13 extends from the inside of the handheld portion to the outside of the handheld portion, while extending, the diameter of the protrusion 13 is gradually reduced, the maximum diameter of the protrusion 13 is larger than the maximum distance of the second sliding slot, and the protrusion 13 is connected with the connecting sleeve through a return spring 14.

The second sliding groove is arranged in a zigzag manner, the diameter of the protrusion 13 is reduced while the protrusion 13 extends outwards from the inside of the handheld part, the maximum diameter of the protrusion 13 is larger than the maximum distance between the zigzag sliding grooves 15, therefore, the protrusion 13 can be clamped in the zigzag sliding grooves 15, the protrusion 13 is connected with the connecting sleeve through the return spring 14, when acting force is not applied to the protrusion 13, the spring is in a natural state, the protrusion 13 is clamped in the zigzag sliding grooves 15, the protrusion 13 cannot move, the position of the second test probe is fixed, when acting force is applied to the protrusion 13, the return spring 14 is in a compressed state, the protrusion 13 is not clamped by the zigzag sliding grooves 15, at the moment, the protrusion 13 can be pushed to move in the zigzag sliding grooves 15, the needle head of the second test probe is pushed out of the connecting sleeve, when the extending length of the needle head meets the required requirement, the acting force, the position of the second test probe may be fixed.
