Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of remote control processing, in particular to a clamp for a welding head. Background Art
[0002] After the electronic components on the control board inside the remote control are welded, the pins of the electronic components often extend for a distance. The longer the extended length, the more likely it is to cause a short circuit. Therefore, pliers are often used to cut off the extended part. However, since there are many electronic components on the control board, this undoubtedly affects the cutting of the pins and easily scratches the operator's hands. In order to facilitate cutting, operators often use pliers at an angle. When cutting, the pins are likely to have sharp tips, and the presence of the tips makes it easier to scratch the operator's hands. Utility Model Content
[0003] The utility model provides a welding head clamp to solve the above-mentioned shortcomings of the prior art, facilitates the flush trimming of the extended section of the pin, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:
[0005] A welding head clamp comprises a ring, wherein an upper plate is provided at the upper end of the ring, two pairs of guide holes are symmetrically opened on the upper plate, a middle hole is opened on the upper plate, and the extended section of the pin extends out of the middle hole, so as to facilitate the cutting operation of the pin with a predetermined length.
[0006] A movable rod is inserted into the guide hole, and a cutter is arranged on the movable rod on the same side. The inner end of the cutter is a blade-shaped structure. Connecting convex plates are arranged at both ends of the cutter. The outer wall of the connecting convex plate is provided with a convex portion. An action rod is arranged on the inner side of the connecting convex plate. The cutting operation of the pin is facilitated by the movement of the cutter. A pair of upper extension vertical plates are installed on the upper plate. A middle convex plate is arranged at the lower end of the upper extension vertical plate. A cross bar is arranged on the middle convex plate. The convex portion is sleeved on the cross bar. Springs are sleeved at both ends of the cross bar. The springs are arranged between the convex portion and the middle convex plate. The arrangement of the springs can automatically restore the cutter to its initial state after the cutting is completed, so as to facilitate the shearing operation again. A pair of inclined plates are rotatably arranged on the inner side of the upper end of the upper extension vertical plate. The inclined plates are arranged crosswise with each other. An outer support plate is arranged at the lower end of the inclined plate. A vertical support hole is opened on the outer support plate. The action rod passes through the vertical support hole. A folding connecting rod is arranged at the upper end of the inclined plate. By applying a force to the folded connecting rod, the angle between the inclined plates can be reduced, and then the vertical support hole acts on the action rod, so that the cutters are brought closer to each other, and the pins are cut off.
[0007] Furthermore, an elastic ring is provided on the outer periphery of the lower end of the ring, and the elastic ring acts on the outer wall of the control board, so as to prevent the ring from scratching the control board during the cutting operation.
[0008] Furthermore, a handle is provided at the upper end of the folding connecting rod to facilitate the rotation of the inclined plate, thereby facilitating the cutting operation.
[0009] Furthermore, a pair of bosses are symmetrically provided on the outer circumference of the ring, a concave plate is installed on the boss, a sleeve is provided on the upper end of the concave plate, a movable tube is movably provided in the sleeve, a conical shell is provided at the lower end of the movable tube, the outer wall of the conical shell is a conical structure, and the upper end of the outer wall of the conical shell is a small end, and a plurality of shrinkage grooves are provided on the conical shell. Through the set conical shell, when the movable tube is pulled upward, it is convenient to position and constrain the pin through the conical shell to avoid pin splashing during cutting.
[0010] Furthermore, a pull head is provided at the upper end of the moving tube to facilitate the operator to pull the moving tube.
[0011] The advantages of the above technical solution are:
[0012] The utility model facilitates the cutting operation of the extended section of the pin, can avoid damage to the control board during the cutting operation, and can ensure the flatness of the pin end during the cutting. BRIEF DESCRIPTION OF THE DRAWINGS
