[0037] The present utility model provides a kind of clamp tool 100.

[0038] The clamp tool 100 in the technical solutions of the present utility model is mainly used for clamping probe (not shown in the drawing), of course, clamp tool 100 can also clamp other smaller size articles, which is not limited here. The following will take clamping probe as an embodiment to introduce the present scheme in detail:

[0039] Referring to Figures 1 to 3In one embodiment of the utility model, the clamping tool 100 includes a clamp 10 and a locking component 30, the clamp 10 includes two clamping pieces 11, the two ends of the two clamping pieces 11 are hingedly connected through a hinge structure 50, to make the two ends of the clamp 10 form a clamping end 113 and a free end 115 respectively;

[0040] The locking component 30 is connected with the clamp 10 and is arranged between the hinge structure 50 and the free end 115, and the locking component 30 can make the clamping end 113 have a clamping state of clamping a probe and a release state of releasing the probe.

[0041] The utility model technical scheme can make the clamping end 113 of the clamp 10 have the clamping state of clamping the probe and the release state of releasing the probe by arranging the two clamping pieces 11 of the clamp 10 in a hingedly connected mode and arranging the locking component 30 on the clamp 10. When in use, the clamping end 113 of the clamp 10 can be released by unlocking the locking component 30, and at this time, the needle taking or releasing operation can be performed. By locking the locking component 30, the clamping end 113 of the clamp 10 has the clamping state, and at this time, the clamping state of the clamp 10 can be maintained without the operator applying external force to the clamping tool 100 all the time, which can effectively relieve the tension or fatigue of the operator and improve the convenience of installing the probe.

[0042] The two clamping pieces 11 in the embodiment can be clamping pieces or clamping rods, and the two clamping pieces 11 are hingedly connected through a hinge shaft. Of course, the two clamping pieces 11 can also be formed with a hinge shaft, as long as the hinge connection between the two clamping pieces 11 can be realized, and the specific form of the hinge structure 50 is not limited.

[0043] In one embodiment, the hinge structure 50 can be arranged at the middle position between the clamping end 113 and the free end 115 of the clamp 10, or can be arranged at any position between the clamping end 113 and the free end 115. The hinge structure 50 is arranged at the position close to the clamping end 113, so that the unlocking operation can be more labor-saving due to the principle of leverage.

[0044] The locking component 30 can make the clamping end 113 of the clamp 10 maintain the clamping state for a long time, and the operator does not need to apply external force to the clamp 10 with hands during this period, which can effectively release the holding pressure of the operator. When the needle taking or releasing operation is needed, the locking component 30 is unlocked to switch from the clamping state to the release state, that is, the operator only needs to exert force for a moment when taking or releasing the needle, which can save labor for the operator.

[0045] In an embodiment of the utility model, two clamping pieces 11 are further formed with profiling grooves 111 at the clamping end 113, and the profiling grooves 111 are oppositely arranged.

[0046] Please refer to Figures 1 to 3 By arranging profiling grooves 111 at the end of the two clamping pieces 11, the profiling grooves 111 are matched with the shape of the clamped article, thereby increasing the contact area between the clamping end 113 and the clamped article and improving the reliability of the clamp 10 in clamping the article. For example, when the clamped article is a probe, the profiling grooves 111 are arc-shaped grooves, so that the damage to the probe during the needle taking and placing operation can be avoided, and the flying needle condition can also be avoided.

[0047] Refer to Figure 1 In an embodiment of the utility model, the locking component 30 comprises:

[0048] The elastic member 31 is arranged between the free end 115 and the hinged structure 50, and the two ends of the elastic member 31 are elastically abutted against the two clamping pieces 11 respectively, so that the clamping end 113 maintains the clamping state;

[0049] The two clamping pieces 11 form an unlocking area (not marked in the figure) between the elastic member 31 and the free end 115, and when the unlocking area is subjected to an external force, the clamping end 113 can be switched from the clamping state to the release state.

[0050] In the technical scheme of an embodiment of the utility model, the elastic member 31 can be a spring or a piece with elasticity, and the elastic member 31 is normally in the elastic release state, so that the free end 115 of the two clamping pieces 11 can be driven to be in a state of moving away from each other, and at this time, the clamping end 113 of the two clamping pieces 11 can be made to be in a state of moving close to each other and being tightened. Generally, the elastic member 31 is arranged at a position close to the hinged structure 50, so that the operation of unlocking can be labor-saving.

[0051] In the technical scheme of an embodiment of the utility model, the area between the free end 115 and the elastic member 31 of the two clamping pieces 11 is formed as an unlocking area, and in the absence of the handle 60, the clamping piece 11 itself can be formed as an unlocking structure, at this time, the operator can make the free end 115 of the two clamping pieces 11 move close to each other by applying an inward force to the two clamping pieces 11 with two fingers, so that the clamping end 113 of the two clamping pieces 11 moves away from each other and is switched to the release state. The structure of this scheme without the handle 60 is relatively simple, but the two clamping pieces 11 need to be arranged in a sheet shape to increase the contact area and facilitate the operation of the operator.

[0052] Refer to Figures 2 to 3In an embodiment of the utility model, the clamping tool 100 further includes handle 60, the inside of handle 60 forms accommodating cavity 61, one end of handle 60 is further equipped with the through hole 63 that communicates accommodating cavity 61, the clamp 10 is located the inside of accommodating cavity 61, the clamping end 113 passes through the through hole 63 and extends the outside of accommodating cavity 61,

[0054] In the technical scheme of one embodiment of the utility model, the handle 60 is provided, and the clamp 10 and the locking component 30 are arranged in the accommodating cavity 61, so that the operator can conveniently hold the handle 60, and the locking component 30 can be protected. At this time, the operator's hand cannot directly apply external force to the unlocking area of the two clamping clamps, so the unlocking member 33 is connected with the clamp 10 to indirectly apply external force to the unlocking area to realize the unlocking operation. The surface of the handle 60 can also be provided with an anti-skid structure to increase the friction between the handle 60 and the operator's hand to improve the reliability of holding. The anti-skid structure can be an anti-skid protrusion, an anti-skid stripe, or an anti-skid sleeve.

[0055] In the technical scheme of one embodiment of the utility model, the unlocking member 33 has multiple forms, which can be connected with one of the two clamping members 11 or connected with both of the two clamping members 11, as long as the structure that can protrude from the surface of the handle 60 to facilitate force application. For example, when the unlocking member 33 is connected with one of the two clamping members 11, the structure can be an unlocking rod, a screw and a nut, or the like. When the unlocking member 33 is connected with both of the two clamping members 11, the structure of the unlocking member 33 is relatively complex at this time, but such a structure can make the force applied to the two clamping members 11 uniform, so that the release probe of the clamping end 113 can be uniform.
