Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a parallel clamp comprises a clamp base 1, a clamp member 2, a clamp member 3 and a first elastic reset member 4; the clamp base 1 is provided with a limiting groove 10, the clamping piece 3 comprises a left clamping piece 31 and a right clamping piece 32, limiting bosses 30 are arranged on the left clamping piece 31 and the right clamping piece 32 respectively, the left clamping piece 31 and the right clamping piece 32 are arranged in parallel, and the limiting bosses 30 on the left clamping piece 31 and the right clamping piece 32 are arranged in the limiting groove 10 in a bilaterally symmetrical and slidable manner; the first elastic reset piece 4 is provided with two pieces, wherein one piece is arranged between the limiting boss 30 of the left clamping piece 31 and the left side end of the limiting groove 10, and the other piece is arranged between the limiting boss 30 of the right clamping piece 32 and the right side end of the limiting groove 10; the clamp 2 can drive the limiting bosses 30 on the left clamp piece 31 and the right clamp piece 32 to move away from each other.

Furthermore, the clamp 2 comprises a left clamp 21, a right clamp 22, a left handle 23 and a right handle 24, one end of the left clamp 21 is abutted against the limit boss 30 of the left clamp 31, the other end of the left clamp is hinged with the clamp base 1, and the left handle 23 is fixedly connected with the left clamp 21 at the hinged point of the left clamp 21; one end of the right clamp 22 is abutted to the limit boss 30 of the right clamp 32, the other end of the right clamp is hinged to the clamp base 1, the right handle 24 is fixedly connected with the right clamp 22 at the hinged point of the right clamp 22, and the left clamp 21 and the right clamp 22 are arranged in bilateral symmetry.

Furthermore, the hinge point of the left clamp 21 and the clamp base 1 is the same hinge point as the hinge point of the right clamp 22 and the clamp base 1.

Specifically, in current pliers, the overwhelming majority all directly adopts two pincers spare articulated structures to form, and articulated structure's swing mode is the arc swing, can know by lever principle, and this structure can lead to when the centre gripping article, and the article is kept silent and is close the earlier atress in the place of pin joint more, and the atress is bigger. In some special cases or situations, the existing pliers structure may cause damage to the object being gripped, so that parallel pliers are required to make the object being gripped in a uniform stress condition. The left clamping piece 31 and the right clamping piece 32 are arranged in parallel, so that the stress condition of an object is uniform when the object is clamped by the left clamping piece 31 and the right clamping piece 32, the left clamping piece 31 and the right clamping piece 32 move by the clamping piece 2 driving the limiting boss 30 to move, the moving position and the moving direction of the limiting boss 30 are controlled by the limiting groove 10, and the left clamping piece 31 and the right clamping piece 32 only do opposite linear motion. The left handle 23 and the right handle 24 are held by a human hand, and pressure is applied, so that the ends of the left handle 23 and the right handle 24 away from the hinge point swing and approach each other, and meanwhile, the ends of the left clamp 21 and the right clamp 22 away from the hinge point swing in the opposite direction and move away from each other, and the limiting bosses 30 on the left clamp 31 and the right clamp 32 are driven to slide in the opposite directions, so as to drive the left clamp 31 and the right clamp 32 to move away from each other. When the person evacuates from the room with pressure applied by hand, the left clamping piece 31 and the right clamping piece 32 can automatically approach each other and be restored by the elastic force of the two first elastic restoring pieces 4 installed at the side ends of the limiting boss 30 and the limiting groove 10. The parallel clamp can make the clamped object uniformly stressed.

Further, all be equipped with guide post 33 on left folder 31 and the right folder 32, the both sides of pincers seat 1 are equipped with guide sleeve 11 to the upper and lower both sides of spacing groove 10 all are equipped with guide sleeve 11, and guide post 33 slidable sets up in guide sleeve 11. The arrangement direction of the guide post 33 is perpendicular to that of the limiting boss 30, the direction of the guide sleeve 11 is parallel to that of the limiting groove 10, and the left clamping piece 31 and the right clamping piece 32 are ensured to be in a straight line to do linear motion all the time in a three-point positioning mode through the guide sleeve 11 arranged on the upper side and the lower side of the limiting groove 10 and the limiting groove 10.

Furthermore, the left handle 23 and the right handle 24 are provided with a second elastic reset piece 5 at the lower side of the hinge point to connect the two. The first elastic reset piece 4 can drive the left and

right nipper pieces

21 and 22 to reset by driving the limit boss 30 to reset, and the elastic force of the second elastic reset piece 5 can assist the process.

Furthermore, one end of the left clamp 21 far away from the hinge point and one end of the left handle 23 far away from the hinge point are arranged on the same side, and the right clamp 22 and the left clamp 21 are identical in structure. This arrangement allows the left clamp 21 and the left handle 23 to move in opposite directions away from the end of the hinge point.

Further, the first elastic resetting piece 4 and the second elastic resetting piece 5 are both compression springs.

Further, this parallel clamp still includes left splint 6 and right splint 7, the tip of left side folder 31 and right folder 32 colludes the form setting, the middle part of left splint 6 and right splint 7 respectively with the left folder 31 and the right folder 32 collude form tip fixed connection. The pressure applied by the left clamping piece 31 and the right clamping piece 32 to the left clamping plate 6 and the right clamping plate 7 is enabled to be in the middle part thereof, and the uniform stress is ensured.
