In view of the above, the utility model provides tweezers, which aims to solve the problem that whether the probes are clamped or not completely depends on the force of loading staff in the process of transferring the probes by using the traditional tweezers, so that the operation is very inconvenient. Fig. 1 to 4 are schematic structural views of tweezers according to an embodiment of the present utility model.

Referring to fig. 1 to 2, the forceps 100 according to the present utility model includes a main body portion 1, a holding portion 2 and a locking member 3. The clamp portion 2 includes two clamp arms 21 extending in parallel in the first direction M, the two clamp arms 21 are connected to the main body portion 1, respectively, and the two clamp arms 21 have a clamped state in abutment with each other. The locking member 3 is rotatably mounted to the clamping portion 2 to retain the two clamp arms 21 in the clamped condition when the locking member 3 is rotated to the locked position.

In the solution of the present utility model, the forceps 100 comprises a main body portion 1 and a holding portion 2, the holding portion 2 comprises two clamping arms 21, and the two clamping arms 21 can be close to each other to abut against each other, so as to hold an object between the two clamping arms 21. In addition, the tweezers 100 further comprise a locking member 3, and the two clamping arms 21 can be limited in a clamping state by rotating the locking member 3, so that the tweezers 100 can stably clamp objects, a user does not need to pinch the tweezers 100 forcefully, and the operation is more convenient.

In some embodiments, each clip arm 21 includes a first portion 21a connected to the body portion 1 and a second portion 21b connected to the first portion 21 a. An arc groove 31 is arranged on one side of each first part 21a facing the second part 21b, and the two arc grooves 31 are communicated with each other and are enclosed to form an annular groove. The locking member 3 includes two arcuate rotating portions 32 which are in one-to-one correspondence with the clip arms 21 and extend in the first direction M, one end of each arcuate rotating portion 32 is connected to the second portion 21b of the corresponding clip arm 21, and the other end is inserted into the corresponding arcuate groove 31 in the first direction M. When the two clamping arms 21 are in the clamping state, a part of at least one arc-shaped rotating part 32 is inserted into one arc-shaped groove 31, and the other part of the arc-shaped rotating part 32 is inserted into the other arc-shaped groove 31.

In practical application, when the two clamping arms 21 are in a clamping state of abutting each other, the two arc-shaped grooves 31 can be mutually communicated and enclosed to form an annular groove. At this time, the two arc rotating parts 32 can rotate in the two arc grooves 31, when the two arc rotating parts 32 rotate by a certain angle, at least one of the two arc rotating parts 32 can be partially inserted into one arc groove 31, and the other part can be inserted into the other arc groove 31, and at this time, the side walls of the two arc grooves 31 limit the arc rotating parts 32. Therefore, the second portions 21b of the two clamping arms 21 cannot be separated from each other because the arc-shaped rotating portion 32 is limited, so that the two clamping arms 21 are limited in the clamping state.

In some embodiments, the arc-shaped rotating portion 32 is configured to cooperate with the corresponding arc-shaped slot 31 to limit the arc-shaped rotating portion 32 from moving along the first direction M in a direction away from the first portion 21a, so that the arc-shaped rotating portion 32 cannot be easily separated from the arc-shaped slot 31, and the connection between each first portion 21a and the corresponding second portion 21b is more stable.

In some embodiments, the two arc-shaped grooves 31 are symmetrically disposed along the interval of the two first portions 21a, and each arc-shaped groove 31 includes an arc-shaped section extending around the axis of the first direction M and a limiting section connected to the arc-shaped section, and the limiting section is disposed along the radial extension of the arc-shaped section. Each arc-shaped rotating portion 32 includes a first insertion section corresponding to the arc-shaped section and a second insertion section corresponding to the limiting section.

Specifically, the limiting section is disposed along the radial extension of the arc-shaped section, so that the extending directions of the limiting section and the arc-shaped section are different, so that the arc-shaped rotating portion 32 cannot be easily separated from the arc-shaped groove 31, and the connection between each first portion 21a and the corresponding second portion 21b is more stable. The arc-shaped rotating portion 32 is also difficult to directly insert into the arc-shaped groove 31 in the first direction M, but the arc-shaped rotating portion 32 can be screwed into the arc-shaped groove 31 from the opening of the arc-shaped groove 31, and the installation can be completed as well.

In some embodiments, the second portion 21b has a fully engaged use position with the first portion 21 a. The inner wall of the arc-shaped groove 31 is provided with a positioning side groove, and the arc-shaped rotating part 32 is provided with a positioning protrusion corresponding to the positioning side groove, so that the corresponding arc-shaped rotating part 32 is positioned to a use position when the positioning protrusion is matched and connected with the positioning side groove.

The two second portions 21b need only be rotated by a certain angle, and the two arc-shaped rotating portions 32 are limited by the side walls of the arc-shaped grooves 31, so that the two clamp arms 21 are maintained in a clamped state. When the second portion 21b is completely attached to the first portion 21a, the two arc-shaped rotating portions 32 are respectively inserted into one arc-shaped groove 31, so that the two arc-shaped rotating portions 32 are not limited, and the two clamping arms 21 can be separated from the clamping state.

When the two clamping arms 21 need to be separated from the clamping state, the two second portions 21b need to be rotated to a specific angle to enable the two arc-shaped rotating portions 32 to be respectively inserted into one arc-shaped groove 31, so that the two clamping arms 21 can be separated from the clamping state. Therefore, in some embodiments, the inner wall of the arc-shaped groove 31 is provided with a positioning side groove, and the arc-shaped rotating portion 32 is provided with a positioning protrusion corresponding to the positioning side groove, so that the two second portions 21b can be accurately rotated to the use position, and the two clamping arms 21 can be disengaged from the clamping state more quickly and smoothly. In addition, when the positioning protrusion is connected with the positioning side groove in a matching manner, the connection between each first portion 21a and the corresponding second portion 21b is more stable, so that the use is convenient for users.

In use, the forceps 100 of the present utility model requires relative rotation of the first portion 21a and the second portion 21b about an axis in the first direction M so that the two arms 21 remain in the clamped condition or are disengaged from the clamped condition. The user thus needs to frequently rotate the first portion 21a or the second portion 21b when using the forceps 100. Thus, in some embodiments of the utility model, the outside of either first portion 21a and either second portion 21b is provided with a booster. When the device is used, a user can rotate the first part 21a and the second part 21b through the boosting part, so that the operation is more convenient.

Furthermore, in another embodiment of the present utility model, a boosting part is provided on the outer side of either the first portion 21a or the second portion 21b, and the user can rotate the first portion 21a or the second portion 21b by the boosting part, which can also rotate the first portion 21a and the second portion 21b relatively. The specific structure of the boosting part may be a block structure or a rod structure, and is not particularly limited herein.

Referring to fig. 3 and 4, in some embodiments, two clamping arms 21 are respectively provided with a mounting hole 211 and a locking slot 212. The locking member 3 includes a rectangular lock sleeve 33, the rectangular lock sleeve 33 is disposed through the two mounting holes 211, and the rectangular lock sleeve 33 is configured to be turned into the two locking grooves 212 when the two clamp arms 21 are in the clamped state, so as to limit the two clamp arms 21 in the clamped state.

When the loop-shaped lock sleeve 33 is rotated into the two locking grooves 212, a partial region of the two clip arms 21 adjacent to the locking grooves 212 is limited by the loop-shaped lock sleeve 33. When the inner diameter of the lock sleeve 33 is smaller, the lock sleeve 33 can limit the two clamping arms 21 in the clamping state, thereby being convenient for users to use.

In some embodiments, two clamp arms 21 are oppositely disposed along the second direction N. In the first direction M, the dimensions of the loop-shaped lock sleeve 33 in the second direction N gradually decrease from the side of the loop-shaped lock sleeve 33 away from the locking groove 212 to the side of the loop-shaped lock sleeve 33 near the locking groove 212. The dimensions of the lock sleeve 33 in the second direction N are gradually reduced, so that the lock sleeve 33 can limit the two clamping arms 21 more tightly when rotating into the two locking grooves 212, thereby keeping the two clamping arms 21 in a clamped state.

The lock sleeve 33 can limit the two clamping arms 21 when being turned into the two locking grooves 212, but in use, the lock sleeve 33 can be separated from the two locking grooves 212, so that the probe can be accidentally dropped. Thus, in some embodiments, the locking groove 212 has a slot opening, and the slot wall of the locking groove 212 includes a bottom wall disposed opposite the slot opening, and a first arcuate sidewall 213 connected between the bottom wall and the slot opening. The first arc-shaped side wall 213 is provided on one side of the locking groove 212 near the mounting hole 211, and the first arc-shaped side wall 213 is recessed inward toward the mounting hole 211 in the radial direction of the notch so as to be limited to the outside of the loop-shaped lock sleeve 33 in the axial direction of the notch when the two clamp arms 21 are in the clamped state.

When the loop-shaped lock sleeve 33 is turned into the two locking grooves 212, the first arc-shaped side wall 213 can limit part of the loop-shaped lock sleeve 33 positioned in the locking groove 212, so that the loop-shaped lock sleeve 33 is prevented from being separated from the locking groove 212. When the clip is specifically applied, the loop-shaped lock sleeve 33 can bypass the first arc-shaped side wall 213 through elastic deformation and enter the locking groove 212, and when no external force exists, the loop-shaped lock sleeve 33 is difficult to separate from the locking groove 212 under the limit of the first arc-shaped side wall 213, so that the loop-shaped lock sleeve 33 is more stable in limit of the two clip arms 21, and the two clip arms 21 are more stable in clamping.

In some embodiments, friction lines are respectively disposed on one side of the two clamping arms 21, which are close to each other, and the two friction lines are disposed away from the main body portion 1 and are opposite to each other. In the present utility model, the probe held by the forceps 100 is very minute, and this makes it possible for the probe to fall off when the two clamp arms 21 hold the probe. Therefore, the two clamping arms 21 are respectively provided with friction lines, and the two friction lines are far away from the main body part 1 and are oppositely arranged, so that when the tweezers 100 clamp probes, the friction lines can increase the movable resistance between the probes and the clamping arms 21, and the probes are prevented from falling accidentally.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
