Further, joint portion is equipped with a draw-in groove 22, draw-in groove 22 be used for with treat the 5 joints of fixed pin on the transport article 4, draw-in groove 22 entrance with 5 interference fit of fixed pin.

As shown in fig. 2, 4 and 5, in the present embodiment, the locking groove on the handle buckle is used for being clamped with the fixing pin on the object to be carried, so as to implement the locking and anti-loosening function of the handle; wherein draw-in groove entrance and fixed pin interference fit realize locking effect.

Further, draw-in groove 22 is including the relative first joint face and the second joint face that sets up, the second joint face is for keeping away from the face of connecting portion 21, the second joint face has guide part 23 to the outer extension, be equipped with on the guide part 23 with the guide surface that the second joint face is connected.

In fig. 5, a side view of the handle fastener is shown, wherein the locking groove comprises a first locking surface and a second locking surface, the second locking surface extends outwards to form a guide part, and the guide part is provided with a guide surface which mainly plays a role of guiding and locking the fixing pin with the locking groove; the innermost part of the clamping groove is an arc surface, the diameter of the optimized arc surface is the same as that of the fixing pin, and the fixing pin is buckled and attached to the handle at the position, so that the locking and anti-loosening functions are realized.

In this embodiment, the guide surface, the first clamping surface of the clamping groove and the bottom surface of the clamping groove are designed into an arc-shaped structure, wherein the guide surface, the first clamping surface and the bottom surface of the clamping groove can be decomposed into three sections of structures, as shown in fig. 5, the decomposition of each section of arc does not correspond to the guide surface, the first clamping surface and the like, and only is the function of the section of structure for convenience of explanation and the like, wherein in principle, the movement track of the fixing pin is set as shown by a line Q, an arc line of an AB section on the handle buckle mainly plays a guiding role, and the fixing pin in a matching section is not in contact with the handle buckle, so that errors existing in products, supporting bodies and the handle and assembling errors formed by assembling together cannot be eliminated, and the tail structure of the handle buckle is required to ensure that the fixing pin; the BC section arc line plays a role in locking and looseness prevention, wherein an inlet of the clamping groove is formed in the BC section arc line, a fixing pin and the handle buckle are assembled in a laminating-interference fit-laminating process on the BC arc line, the CD section is the locking position of the fixing pin and the clamping groove in the handle buckle, the fixing pin is laminated with the clamping groove in the arc line section, and the bottom surface of the fixing pin is laminated with the bottom surface of the arc line section to achieve the locking and looseness prevention functions in consideration of production errors and assembly errors; preferably, the arc of the AC segment in this embodiment is selected from an ellipse segment as shown in fig. 6, wherein the length of the AC segment can be extended or shortened as required.

Furthermore, the clamping position of the clamping groove 22 and the fixing pin 5 and the guide part 23 are located on two sides of the first mounting hole 24.

The position with fixed pin and draw-in groove joint sets up the both sides at first mounting hole with the guide part in this embodiment for this handle has the locking function of vibrations after installing, the back is good with the draw-in groove joint to the fixed pin, the bottom of fixed pin and draw-in groove contact cooperation can, figure 5 and figure 7 have given the locking principle of this handle, the handle is detained after the lock targets in place, if will break away from the fixed pin, then need produce the rotary motion around pivot hole centre of a circle O, to the visual angle that figure 7 shows, its direction of rotation is anticlockwise. If the handle buckle is to realize the anti-vibration and anti-loosening function, a reverse moment for preventing the handle buckle from rotating anticlockwise needs to exist, and the principle of generation and action of the reverse moment is as follows:

when the product is in a long-term vibration environment, the acting force of the fixing pin on the tail part of the handle buckle can be decomposed into F1 and F2. Wherein, F1 is the force when the product is shocked to generate the tendency of moving away, F2 is the force caused by the interference of the fixed pin and the handle buckle at the BC section. The torque of F1 to center O is M1 ═ F1 × L1, the torque of F2 to center O is M2 ═ F2 × L2, and the directions of M1 and M2 (in the view of the drawing) are clockwise. The sizes of M1 and M2 determine the strength of the shock-proof and anti-loosening capability of the handle, and L1 and L2 are fixed values, so that the sizes of F1 and F2 determine the sizes of M1 and M2, and further determine the shock-proof and anti-loosening capability of the handle. When the product is in a vibration environment, the sizes of the F1 and the F2 are positively correlated with the vibration intensity, namely the more intense the vibration is, the larger the values of the F1 and the F2 are, and the more favorable the looseness prevention of the handle is.

Further, an opening of the mounting groove 13 deviates from the grabbing part 11, a second mounting hole 14 is formed in the mounting groove 13, at least two positioning columns 15 are arranged beside the second mounting hole 14, and the positioning columns 15 are in positioning fit with the positioning holes 25.

In this embodiment, establish the mounting groove in the extension side of handle body, this mounting groove is installed with the connecting portion cooperation that the handle was buckled, is equipped with the second mounting hole corresponding with the connecting portion that the handle was buckled in the mounting groove, and the other locating column that sets up of second mounting hole cooperates with the locating hole on the connecting portion, guarantees the accurate installation of this handle body and handle knot.

Further, the mounting groove 13 is disposed at an end of the extension portion 12 away from the grasping portion 11.

The mounting groove setting in this embodiment is at the lateral surface of extension, realizes the installation with the handlebar grips for the mounting means is simple and convenient more.

Further, the second mounting hole 14 and the first mounting hole 24 are coaxially arranged and are used for penetrating through the screw 3.

The first mounting hole on the connecting portion and the second mounting hole in the mounting groove all are used for through the screw in this embodiment, ensure that the screw can pass handle buckle and handle main part smoothly, finally fix the handle buckle on handle main part completely.

Further, the extension portions 12 are symmetrically disposed with the grasping portion 11 as a center of symmetry. The handle is the axisymmetric structure in this embodiment, simple structure and convenient to use.

Further, the connection portion 21 of the handle buckle 2 is matched with the installation groove 13 of the extension portion 12. The connecting part and the mounting groove in the embodiment are completely matched and arranged, and the outer side surface of the connecting part is attached to the inner side surface of the mounting groove, so that the handle buckle only has one degree of freedom of translation along the screw as the axial direction after being mounted,

the handle in this embodiment is composed of a handle body and a handle buckle. The handle buckle and the fixed pin corresponding to the support body can form a cam rotating pair, and when the handle buckle is in place, the handle cannot be loosened under the condition of non-manual intervention even in a long-term vibration environment; the more severe the degree of vibration, the stronger the grip's anti-loosening ability.

Further, the screw 3 is a plug screw. In the embodiment, the plug screw is used as a screw for fixedly connecting the extension part and the handle buckle, and the product has high hardness, good toughness, excellent wear resistance and heat resistance, is suitable for a precision die, and can obviously prolong the service life of the precision die.
